Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
All living cells in an animal's body require energy to power the various chemical processes going in inside them. This energy is ultimately supplied by the food that animals eat. These chemical processes are collectively referred to as metabolism, and one of the byproducts of metabolism is heat. Metabolic rates vary significantly between species. Warm-blooded animals (birds and mammals) have metabolic rates about five to ten times higher than those of similarly sized cold-blooded ones (reptiles, amphibians, and fishes). And it is precisely because birds and mammals have such high metabolic rates that they are able to keep their bodies warm.
The terms warm-blooded and cold-blooded are still in everyday use, but they are not entirely precise. Anyone who has handled a snake knows this because a snake’s body actually feels quite warm. But very little of the snake’s body heat originates internally, from its cells, most of it having been supplied from the outside, either by the sun or by a heat lamp. Instead of referring to reptiles as cold- blooded, they are best described as ectothermic, meaning “outside heat”. Similarly, birds and mammals are said to be endothermic, meaning “inside heat”.
There are advantages and disadvantages to each thermal strategy. Reptiles are usually sluggish first thing in the morning, their body temperatures having dropped during the cool of the night. Accordingly, they have to bask in the sun to raise their body temperatures, but once they have warmed up sufficiently, they can go about their business. By altering between the sun when they are too cool, and the shade when they are too warm, many reptiles are able to maintain their body temperatures at optimum levels of about 95°F or more. Endotherms, on the other hand, maintain temperatures of about 98°F all the time, so they are always ready for action.
I used to keep a crocodile. He had very sharp teeth, and I had to be careful how I handled him during the daytime, when he was warm. But I could do whatever I wanted at night, when he was cold, without any fear of being bitten. The obvious disadvantage of being ectothermic is that the animal’s activity levels are dependent upon the environment. But its low metabolic rates mean that it requires far less food, which is an advantage. I used to feed the crocodile a tiny piece of liver once a week, while the family cat demanded three meals every day. We should therefore not think that reptiles are inferior to mammals and birds; they are just different.

What can be inferred from the passage?

The culture of Vietnam is one of the oldest in Southeast Asia, with the ancient Bronze age Đông Sơn culture being widely considered one of its most important progenitors. In spite of geographically Southeast Asian, Vietnamese culture was heavily influenced by Chinese culture in terms of politics, government, social and moral ethics, and art due to 1000 years of Chinese rule. Thus, Vietnam is considered to be part of the East Asian cultural sphere together with China, Japan, Korea and Taiwan.

Following independence from China in the 10th century, Vietnam began a southward expansion that saw the annexation of territories formerly belonging to the Champa Civilization (now Central Vietnam) and parts of the Khmer Empire (now Southern Vietnam). Gradually, there are minor regional variances in Vietnam's culture due to exposure to these different groups.

During the French colonial period, Vietnamese culture absorbed various influences from the Europeans, including the spread of Catholicism and the adoption of the Latin alphabet. Prior to this, Vietnamese had used both Chinese characters and a script called Chữ Nôm which was based on Chinese but included newly invented characters to represent native Vietnamese words.

In the socialist era, the cultural life of Vietnam has been deeply influenced by government-controlled media and the cultural influences of socialist programs. For many decades, foreign cultural influences from the Western World were shunned, and emphasis was placed on sharing the culture of communist nations such as those in the Soviet Union, Cuba, China, and others.

Some elements generally considered to be characteristic of Vietnamese culture include ancestor veneration, respect for community and family values, handicrafts and manual labour, and devotion to study. Important symbols present in Vietnamese culture include dragons, turtles, lotuses, and bamboo.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Social parasitism involves one species relying on another to raise its young. Among vertebrates, the best known social parasites are such birds as cuckoos and cowbirds; the female lays egg in a nest belonging to another species and leaves it for the host to rear
The dulotic species of ants, however, are the supreme social parasites. Consider, for example, the unusual behavior of ants belonging to the genus Polyergus. All species of this ant have lost the ability to care for themselves. The workers do not forage for food, feed their brood or queen, or even clean their own nest. To compensate for these deficits, Polyergus has become specialized at obtaining workers from the related genus Formica to do these chores
In a raid, several thousand Polyergus workers will travel up to 500 feet in search of a Formica nest, penetrate it, drive off the queen and her workers, capture the pupal brood, and transport it back to their nest. The captured brood is then reared by the resident Formica workers until the developing pupae emerge to add to the Formica population, which maintains the mixed- species nest. The Formica workers forage for food and give it to colony members of both species. They also remove wastes and excavate new chambers as the population increases
The true extent of the Polyergus and dependence on the Formica becomes apparent when the worker population grows too large for existing nest. Formica scouts locate a new nesting site, return to the mixed-species colony, and recruit additional Formica nest mates. During a period that may last seven days, the Formica workers carry to the new nest all the Polyergus eggs, larvae, and pupae, every Polyergus adult, and even the Polyergus queen
Of the approximately 8000 species of ants in the world, all 5 species of Polyergus and some 200 species in other genera have evolved some degree of parasitic relationship with other ants

Which of the following statements best represents the main idea of the passage?

Read the passage carefully and choose the correct answer.

University Entrance Examination is very important in Vietnamese students. High school graduates have to take it and get high results to be admitted to universities. The pressure on the candidates remains very high despite the measures that have been taken to reduce the heat around these exams, since securing a place in a state university is considered a major step towards a successful career for young people, especially those from rural areas or disadvantaged families. In the year 2004, it was estimated that nearly 1 million Vietnamese students took the University Entrance Examination, but on average only 1 out of 5 candidates succeeded. Normally, candidates take 3 exam subjects, and each lasts; 180 minutes for the fixed group of subjects they choose. There are 4 fixed groups of subjects: Group A: Mathematics, Physics, and Chemistry; Group B: Mathematics, Biology, and Chemistry; Group C: Literature, History, and Geography; Group D: Literature, Foreign Language, and Mathematics.

In addition to universities, there are community colleges, art and technology institutes; professional secondary schools, and vocational schools which offer degrees or certificates from a-few-month to 2-year courses.

According to Vietnam's Ministry of Education and Training, there are currently 23 non-public universities, accounting for 11% of the total number of universities. These non-public universities are currently training 119,464 students, or 11.7% of the total number of students. The government is planning to increase the number of non-public universities to 30% by 2007.

University Entrance Examination in Vietnamese is very _______.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions:
If you could travel back in time five centuries, you'd encounter a thriving Aztec empire in Central Mexico, a freshly painted "Mona Lisa" in Renaissance Europe and cooler temperatures across the Northern Hemisphere. This was a world in the midst of the Little Ice Age (A.D. 1300 to   1850) and a period of vast European exploration now known as  the Age of  Discovery. But what if  we could look 500 years into the future and glimpse the Earth of the 26th century? Would the  world seem as different to us as the 21st century would have seemed to residents of the 16th century? For starters, what will the weather be like?
Depending on whom you ask, the 26th century will either be a little chilly or infernally hot.
Some solar output models suggest that by the 2500s, Earth's climate will have cooled back down to near Little Ice Age  conditions. Other studies predict that ongoing climate change and fossil fuel use will render much of the planet too hot for human life by 2300.
Some experts date the beginning of human climate change back to the Industrial Revolution  in the 1800s, others to slash-and-burn agricultural practices in prehistoric times. Either way, tool- wielding humans alter their environment -- and our 26th century tools might be quite impressive indeed.
Theoretical physicist and futurist Michio Kaku predicts that in a mere 100 years, humanity will make the leap from a type zero civilization to a type I civilization on the Kardashev Scale. In  other words, we'll become a species that can harness the entire sum of a planet's energy. Wielding such power, 26th-century humans will be masters of clean energy technologies such as fusion and solar power. Furthermore, they'll be able to manipulate planetary energy in order to control global climate. Physicist Freeman Dyson, on the other hand, estimates the leap to a type I civilization would occur within roughly 200 years.
Technology has improved exponentially since the 1500s, and this pace will likely continue in   the centuries to come. Physicist Stephen Hawking proposes that by the  year 2600, this growth  would see 10 new theoretical physics papers published every 10  seconds. If  Moore's Law holds  true and both computer speed and complexity double every 18 months, then some of  these  studies may be the work of highly intelligent machines.
What other technologies will shape the world of the 26th century? Futurist and author Adrian Berry believes the average human life span will reach 140 years and that the digital  storage of human personalities will enable a kind of computerized immortality. Humans will farm the oceans, travel in starships and reside in both lunar and Martian colonies while robots explore the outer cosmos.

Martin Luther King, Jf, is well- known for his work in civil rights and for his many famous speeches, among which is his moving “I have a dream” speech. But fewer people know much about King’s childhooD. M.L., as he was called, was bom in 1929 in Atlanta, Georgia, at the home of his maternal grandfather. M.L.’s grandfather purchased their home on Auburn Avenue in 1909, twenty years before M.L was bom. His grandfather allowed the house to be used as a meeting place for a number of organizations dedicated to the education and social advancement of blacks. M.L. grew up in the atmosphere, with his home being used as a community gathering place, and was no doubt influenced by it.
M.L.’s childhood was not especially eventfully. His father was a minister and his mother was a musician. He was the second of three children, and he attended all black schools in a black neighborhood. The neighborhood was not poor, however. Auburn Avenue was an area of banks, insurance companies, builders, jewelers, tailors, doctors, lawyers, and other businesses and services. Even in the face of Atlanta’s segregation, the district thrived. Dr. King never forgot the community spirit he had known as a child, nor did he forget the racial prejudice that was a huge barrier keeping black Atlantans from mingling with whites.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions:
One of the most interesting parts of the earth for many people was and continues to be the beautiful world of the sea. People were always attracted to the mysteries of the deep waters when they saw a little part of the under water world on television or in photographs. Due to this intense attraction caused by the mystery of the waters, more and more people choose to practice scuba diving, which became in time one of the most popular sports around the world. Scuba diving is a complex sport that requires some research before being understood at its real value. In order for someone to practice it, it is required for them to take some courses so accidents can be avoided.
Scuba diving is not only about diving and observing the amazing environment that exists under the waters. This sport can be transformed into a successful career by those who are truly passionate about it. At the moment, scuba diving has four main areas of interest: recreation purposes, commercial purposes, scientific research and military activity as well. The most frequent reason why people go for scuba diving is because they want to relax in a special way, by having contact with a less known world.
A great thing about this sport is that it can be practiced anytime around the year; however, you should choose the summer if you have problems with low temperatures. Once you take the lessons, you get the basic knowledge before diving, you should talk to a specialist and obtain quality equipment for this activity. For the beginning, you can  only rent scuba diving equipment,  but if you get attached to this sport, then you will have to purchase one of your own at some moment. Some of the most important parts of the scuba gear are the mask, the snorkel, the diving suit, the gloves, the boots and the diving regulator.
If you finally decided to try scuba diving and you already took some scuba courses then you must be thinking about what location to choose. This is one of  the most difficult decisions to  make  as our world is filled with numerous destinations, equally beautiful and interesting. If this passion catches you then you will surely get to visit more and more amazing locations each year. There is    no such thing as the most beautiful waters to scuba diving in as each part has something to offer    and shelters special creatures that should be observed.

According to the passage, which of the interest of scuba diving is NOT mentioned?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Henry is the undisputed star of Dronfield School near Sheffield. Whatever the achievements of other members of the comprehensive school, it is Henry, with his soulful eyes and glossy hair, who has hogged the limelight, appearing on television in Britain and abroad. Yet despite all the public adulation, Henry stirs up no envy or resentment among the 2000 students – in fact, they all adore him. The dog, who first arrived six months ago, is a super dog, who has improved students’ behaviour and encouraged more students to focus on their academic achievement.
Andrew Wainwright, a student at Dronfield School, says there is something magical and calming about being able to interact with Henry during his time at the school’s catch-up classes, and that if he falls behind, that opportunity will be denied. Even doubting staff have finally been won round. Perhaps that is because Henry, who lies on the floor during staff meetings, has also had a calming effect on them.
It was Andrew’s teacher, Wendy Brown and the school counsellor, Julie Smart, who first proposed buying a school dog. “Julie and I were talking one day about how looking after dogs can positively affect children’s conduct,” says Brown. “We did some research and discovered that the presence of pets has been shown to be therapeutic. A number of studies have shown that animals improve recovery after surgery or illness and have a calming influence on people in a lot of settings. Some of my kids can be a handful and some of the children Julie counsels have terrible problems.”
Could the school dog become a craze? Other schools such as the Mulberry Bush, a primary school for children with behavioural problems, have stepped forward to point out they already have one. Rosie Johnston, a Mulberry staff member has been bringing her golden retriever, Muskoka, into school for three years. Apart from being a calming influence, Muskoka even plays his part in literacy lessons. Children at the school can be too shy to read to adults so they read to Muskoka. “Their anxiety about mispronouncing something or getting the words in the wrong order is reduced when they read to him,” says Johnston.
Psychologist Dr Deborah Wells from Queen's University Belfast specialises in animal-human interaction. She believes that the underlying key to the Henry effect is that dogs offer unconditional love and that cheers up adults and children and helps with self-esteem. But traditionalist Chris Woodhead, the former chief inspector of schools says, “I don’t see why a teacher cannot create a positive learning environment through the subject they teach and their personality. Dogs strike me as a bit of a publicity stunt. It’s the kind of sentimental story journalists love.” Despite this sentiment, Henry remains as popular as ever.

Which of the following best summarises Chris Woodhead's viewpoint in paragraph 5?

Education is another area of social life in which information technology is changing the way we communicate. Today's college students may not simply sit in a lecture or a library to  learn about their field. Through their computers and the wonders of virtual reality they can participate
in lifelike simulated experiences. Consider the following scenario of the future of education made possible through developments in information technology.
For children over the age of 10, daily attendance at schools is not compulsory. Some of the older children attend school only once or twice weekly to get tutorial support or instruction from a teacher. For the most part, pupils are encouraged to work online from home. Students must complete a minimum number of study hours per year; however, they may make up these hours by studying at home at times that suit their family schedule. They can log on early or late in the day and even join live classes in other countries. In order to ensure that each student is learning adequately, computer software will automatically monitor the number of hours a week each student studies online as well as that students' learning materials and assessment activities. Reports will be available for parents and teachers. The software can then identify the best learning activities and condition for each individual student and generate similar activities. It can also identify areas of weak achievement and produce special programs adjusted to the students' needs.

Recreational diving or sport diving is a type of diving that uses scuba equipment for the purpose of leisure and enjoyment. In some diving circles, the term "recreational diving" is used in contradistinction to "technical diving", a more demanding aspect of the sport  which  requires greater levels of training, experience and equipment.
Recreational scuba diving grew out of related activities such as snorkeling and underwater hunting. For a long time, recreational underwater excursions were limited by the  amount of  breath that could be held. However, the invention of the aqualung in 1943 by Jacques-Yves Cousteau and its development over subsequent years led to a revolution in recreational diving. However, for much of the 1950s and early1960s, recreational scuba diving was a  sport limited to  those who were able to afford or make their own kit, and prepared to undergo intensive training to use it. As the sport became more popular, manufacturers became aware of the potential market, and equipment began to appear that was easy to use, affordable and reliable. Continued advances in' SCUBA technology, such as buoyancy compensators, modern diving regulators, wet or dry suits,  and dive computers, increased the safety, comfort and convenience of the gear encouraging more people to train and use it.
Until the early 1950s, navies and other organizations performing professional diving were   the only providers of diver training, but only for their own personnel and only using their own    types of equipment. There were no training courses available to civilians who bought the  first  scuba equipment. Professional instruction started in 1959 when the non-profit National Association of Underwater Instructors was formed.
Further developments in technology have reduced the cost of training and diving. Scuba- diving has become a popular leisure activity, and many diving locations have some form of  dive  shop presence that can offer air fills, equipment and training. In tropical and sub-tropical parts of the world, there is a large market in holiday divers, who train and dive while on holiday, but rarely dive  close to home. Generally, recreational diving depths are limited to a maximum of between 30 and 40 meters (100 and 130 feet), beyond which a variety of safety issues make it unsafe to dive using recreation diving equipment and practices, and specialized training and equipment for technical diving are needed.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions. 
      Urbanization degrades the environment, according to conventional wisdom. This view has led many developing countries to limit rural - urban migration and curb urban expansion. But this view is incorrect. There are a number of reasons urbanization can be good for the environment, if managed properly.
      First, urbanization brings higher productivity because of its positive externalities and economies of scale. Asian urban productivity is more than 5.5 times that of rural areas. The same output can be produced using fewer resources with urban agglomeration than without. In this sense, urbanization reduces the ecological footprint. The service sector requires urbanization because it needs a concentration of clients. As services generally pollute less than manufacturing, this aspect of urbanization is also beneficial to the environment.
      Second, for any given population, the high urban density is benign for the environment. The urban economics literature shows that compactness is a key determinant of energy use. High density can make public transport more viable and reduce the length of trips. Urban living encourages walking and cycling rather than driving. Third, environment-friendly infrastructure and public services such as piped water, sanitation, and waste management are much easier and more economical to construct, maintain, and operate in an urban setting. Urbanization allows more people to have access to environment-friendly facilities and services at affordable prices.
     Fourth, urbanization drives innovation, including green technologies. In the long term, environment-friendly equipment, machines, vehicles, and utilities will determine the future of the green economy. Green innovations in Asia's cities will be supported by the region's vast market as the billions of people who will be buying energy-efficient products will create opportunities and incentives for entrepreneurs to invest in developing such products. Finally, the higher standard of living associated with urbanization provides people with better food, education, housing, and health care. Urban growth generates revenues that fund infrastructure projects, reducing congestion and improving public health. Urbanization fosters a pro-environment stance among property owners and the middle class, which is crucial for the introduction and enforcement of environmental laws and regulations.
      Of course, urbanization also comes with costs. Millions of people are migrating to Asian cities and companies are locating there to employ them. Urban sprawl and industrial activities, such as power generation, transportation, construction, garbage and waste disposal, harm the environment. An assessment of the impact of urbanization on the environment must balance its benign and adverse effects.

According to paragraph 4, why is the promotion of an environmentally friendly attitude necessary?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
The green building movement, started in the 1970s as a way to reduce environmental destruction, is changing the way buildings are constructed. In the early years, green builders were a small minority, and their goals of reducing the environmental impact of buildings were considered unrealistic. Now, however, the movement is growing, as builders have been able to take advantage of new technology.
Green builders try to make use of recycled materials, which means less waste in dumps. Also, they reduce environmental impact by reducing the energy requirements of a building. One way is to provide an alternative, non-polluting source of energy. First, with solar panels, it is possible to produce electricity from the rays of the sun. Once installed, they provide energy at no cost and with no pollution.
Another solution is to reduce the amount of energy required in a building. It is possible to cut electricity use noticeably by improving natural lighting and installing low-energy light bulbs. To reduce the amount of fuel needed for heating or cooling, builders also add insulation to the walls so that the building stays warmer in winter and cooler in summer.
One example of this advanced design is the Genzyme Center of Cambridge, the most environmentally responsible office building in America. Every aspect of the design and building had to consider two things: the need for a safe and pleasant workplace for employees and the need to lessen the negative environmental impact. 75 percent of the building materials were recycled materials, and the energy use has been reduced by 43 percent and water use by 32 percent, compared with other buildings of the same size.
In other parts of the world, several large-scale projects have recently been developed according to green building principles. One of these is in Vauban, Germany, in an area that was once the site of army housing. The site has been completely rebuilt with houses requiring 30 percent less energy than conventional ones. These houses, heated by special non-polluting systems, are also equipped with solar panels.
A larger project is under way in China. The first phase of this project will include houses for 400 families built with solar power, non-polluting bricks, and recycled wall insulation. In a second phase, entire neighborhoods in six cities will be built. If all goes well, the Chinese government plans to copy these ideas in new neighborhoods across China.
Green building ideas, on a small or large scale, are spreading. Individuals, companies, and governments are beginning to see their benefits. Not only are they environmentally friendly, green buildings improve living and working conditions and also save money in the long run.A

According to the passage, which of the following statements about green buildings is TRUE?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions. 
      Though the conservation movement had European roots, many observers maintain that the United States has emerged as the world's leader in environmentalism.
       The transcendentalism of the early 1800s and its celebration of the natural world arrived just in time to be trampled underfoot by the ravages of the Industrial Revolution. As forests disappeared under the ax of reckless timber barons, coal became a popular source of energy. Unfettered use of coal in homes and factories resulted in horrific air pollution in cities like London, Philadelphia, and Paris.
      In the 1850s, a carnival huckster named George Gale heard about an immense California redwood that was over 600 years old when Jesus was born. Upon seeing the magnificent tree, nicknamed The Mother of the Forest, Gale hired men to cut the tree down so that its bark could be displayed in his sideshow. The reaction to Gale's stunt, however, was swift and ugly: "To our mind, it seems a cruel idea, a perfect desecration, to cut down such a splendid tree ... what in the world could have possessed any mortal to embark in such a speculation with this mountain of wood?," wrote one editor.
       The growing realization that human industry was obliterating irreplaceable wilderness -- and endangering human health -- resulted in the earliest efforts at managing natural resources. In 1872, Yellowstone National Park was created, the first of what became one of America's best ideas: a network of national parks that were strictly off-limits to exploitation.

Is there life on Mars? Many people have (1) ______ about this question. Some writers    of science-fiction think of people from Mars as little green creatures. Others imagine 'Martians' as monsters with many eyes.
In studying this planet, astronomers have found that life may be possible on Mars. The first (2) _____ of this is that Mars has seasons, just like Earth. In other words, Earth's seasons, such as spring or summer, occur on Mars too. Because these seasons exist, it may be possible for (3) ____and other higher life forms to be found on Mars.
Astronomers also think that perhaps a small (4) ______ of  water vapor could be  found  on Mars. In 1887, an Italian astronomer, Giovanni Schiaparelli, discovered markings on Mars' surface. These markings looked like canals. This finding led astronomers to believe that since water exists on Mars, life forms could exist as well.
 However, there are others who feel that life on Mars is not possible. This is because there is little or no trace of oxygen on the planet. In 1965, the Mariner IV capsule managed to take photographs of the planet. It discovered that the only forms of  life found are vegetation like fungi and mosses. (5) ______ people remain fascinated by the idea that there could one day be life on Mars.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
In the United States, it is important to be on time, or punctual, for an appointment, a class, a meeting, ect... This may not be true in some other countries, however. An American professor discovered this difference while teaching a class in a Brazilian university. The two-hour class was scheduled to begin at 10 A.m., and end at 12 A.m. On the first day, when the professor arrived on time, no one was in the classroom. Many students came after 11 A.m. Although all of the students greeted the professor as they arrived, few apologised for their lateness. Were these students being rude? He decided to study the students’ behavior.
In American university, students are expected to arrive at the appointed hour. On the other hand, in Brazil, neither the teacher nor the students always arrive at the appointed hour. Classes not only begin at the scheduled time in the United States, but they also end at the scheduled time. In the Brazilian class, only a few students left the class at noon, many remained past 12:30 to discuss the class and ask more questions. While arriving late may not be important in Brazil, neither is staying late.
The explanation for these differences is complicated. People from Brazilian and North American cultures have different feelings about lateness. In Brazil, the students believe that a person who usually arrives late is probably more successful than a person who is always on time. In fact, Brazilians expect a person with status or prestige to arrive late, while in the United States, lateness is usually considered to be disrespectful and unacceptable. Consequently, if a Brazilian is late for an appointment with a North America, the American may misinterpret the reason for the lateness and become angry.
As a result for his study, the professor learned that the Brazilian students were not being disrespectful to him. Instead, they were simply behaving the appropriate way for a Brazilian student in Brazil. Eventually, the professor was able to adapt his own behavior to feel comfortable in the new culture.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Rachel Carson was bom in 1907 in Springsdale, Pennsylvania. She studied biology in college and zoology at Johns Hopkins University, where she received her master’s degree in 1933. In 1936, she was hired by the US Fish and Wildlife Service, where she worked most of her life.
Carson’s first book, Under the Sea Wind, was published in 1941. It received excellent reviews, but sales were poor until it was reissued in 1952. In that year, she published The Sea Around Us, which provided a fascinating look beneath the ocean’s surface, emphasizing human history as well as geology and marine biology. Her imagery and language had a poetic quality. Carson consulted no less than 1, 000 printed sources. She had voluminous correspondence and frequent discussions with experts in the field. However, she always realized the limitations of her non-technical readers.
In 1962, Carson published Silence Spring, a book that sparked considerable controversy. It proved how much harm was done by the uncontrolled, reckless use of insecticides. She detailed how they poison the food supply of animals, kill birds, and contaminate human food. At that time, spokesmen for the chemical industry mounted personal attacks against Carson and issued propaganda to indicate that her findings were flawed. However, her work was vindicated by a 1963 report of the President’s Science Advisory Committee.

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the question. 
Nowadays, most people realize that it’s risky to use credit card numbers online. However, from time to time, we all use passwords and government ID numbers on the Internet. We think we are safe, but that may not be true! A new kind of attack is being used by dishonest people to steal IDs and credit card numbers from innocent websurfers. This new kind of attack is called “phishing.”
Phishing sounds the same as the word “fishing,” and it implies that a thief is trying to lure people into giving away valuable information. Like real fishermen, phishers use bait in the form of great online deals or services. For example, phishers might use fake emails and false websites to con people into revealing credit card numbers, account usernames, and passwords. They imitate well-known banks, online sellers, and credit card companies. Successful phishers may convince as many as five percent of the people they contact to respond and give away their personal financial information. 
Is this really a big problem? Actually, tricking five percent of the online population is huge! Currently, more than 350 million people have access to the Internet, and seventy-five percent of those Internet users live in the wealthiest countries on Earth. It has been estimated that phishers send more than three billion scam messages each year. Even by tricking only five percent of the people, phishers can make a lot of money. 
Since there is so much money to make through this kind of scam, it has caught the interest of more than just small-time crooks. Recently, police tracked down members of an organized phishing group in Eastern Europe, who had stolen hundreds of thousands of dollars from people online. The group created official-looking email messages requesting people to update their personal information at an international bank’s website. However, the link to the bank in the message actually sent people to the phishers’ fake website. To make matters worse, further investigation revealed that this group had connections to a major crime gang in Russia. 
How can innocent people protect themselves? Above all, they have to learn to recognize email that has been sent by a phisher. Always be wary of any email with urgent requests for personal financial information. Phishers typically write upsetting or exciting, but fake, statements in their emails so that people will reply right away. Also, messages from phishers will not address recipients by name because they really don’t know who the recipients are yet. On the other hand, valid messages from your bank or other companies you normally deal with will typically include your name.

What suggestion is TRUE according to the last paragraph?

Covering more than 70 percent of our planet, oceans are among the earth’s most valuable natural resources. They govern the weather, clean the air, help feed the world, and provide a living for millions. They also are home to most of the life on earth, from microscopic algae to the blue whale, the largest animal on the planet. Yet we’re bombarding them with pollution. By their very nature—with all streams flowing to rivers, all rivers leading to the sea—the oceans are the end point for so much of the pollution we produce on land, however far from the coasts we may be. And from dangerous carbon emissions to choking plastic to leaking oil to constant noise, the types of ocean pollution humans generate are vast. As a result, collectively, our impact on the seas is degrading their health at an alarming rate. Here are some ocean pollution facts that everyone on our blue planet ought to know.
When we burn fossil fuels, we don’t pollute just the air but the oceans, too. Indeed, today’s seas absorb as much as a quarter of all man-made carbon emissions, which changes the pH of surface waters and leads to acidification. This problem is rapidly worsening—oceans are now acidifying faster than they have in some 300 million years. It’s estimated that by the end of this century, if we keep pace with our current emissions practices, the surface waters of the ocean could be nearly 150 percent more acidic than they are now.
The majority of the garbage that enters the ocean each year is plastic—and here to stay. That’s because unlike other trash, the single-use grocery bags, water bottles, drinking straws, and yogurt containers, among eight million metric tons of the plastic items we toss (instead of recycle), won’t biodegrade. Instead, they can persist in the environment for a millennium, polluting our beaches, entangling marine life, and getting ingested by fish and seabirds.
Where does all this debris originate? While some is dumped directly into the seas, an estimated 80 percent of marine litter makes its way there gradually from land-based sources―including those far inland―via storm drains, sewers, and other routes. Oil from boats, airplanes, cars, trucks, and even lawn mowers is also swimming in ocean waters. Chemical discharges from factories, raw sewage overflow from water treatment systems, and storm water and agricultural runoff add other forms of marine-poisoning pollutants to the toxic brew.
The ocean is far from a “silent world.” Sound waves travel farther and faster in the sea’s dark depths than they do in the air, and many marine mammals like whales and dolphins, in addition to fish and other sea creatures, rely on communication by sound to find food, mate, and navigate. But an increasing barrage of human-generated ocean noise pollution is altering the underwater acoustic landscape, harming—and even killing—marine species worldwide.

As mentioned in paragraph 2, acidification ______________.
