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 “How many hours does it take to make a friend?” (2018), Jeffrey A. Hall describes the types of encounters that build a friendship.
       His study found that hours of time spent together was linked with closer friendships, as was time spent enjoying leisure activities together. Specifically, he found that the chance of making a “casual friend,” as opposed to a mere acquaintance, was greater than 50 percent when people spent approximately 43 hours together within three weeks of meeting. He further found that casual friends evolve into friends at some point between 57 hours after three weeks, and 164 hours over three months. Hall's research also demonstrated, however, that when it comes to time spent developing friendships, quality is more important than quantity. And when it comes to conversation, topics matter. When it comes to building quality relationships, the duration of conversation is not as important as the content. Meaningful conversation is the key to bonding with others. 
       Hall found that when it comes to developing friendships, sharing daily life through catching up and joking around promotes closeness; small talk does not. Consider the inane topics that often come up when you are trapped in an elevator with an acquaintance. Discussing the weather or speculating on how many stops you will make before finally reaching the lobby does not facilitate bonding. Nor does mere proximity. Hall found that obligatory time spent together, such as in a classroom or workplace, does not promote closeness. Friendships require an efficient use of time together. Someone who remembers the details of your life and asks questions about your family, your job, your latest vacation, etc., is much more likely on his or her way to becoming someone you consider a friend, as opposed to an acquaintance.

According to paragraph 2, what conclusion can be drawn from the finding of Jeffrey A. Hall?

During my last couple of years as a student here at Union High, I have noticed that there is nothing to do during our occasional free periods. Hanging around in the hallways or in the library with friends isn't productive or relaxing. The student body council noticed this as well and brought it to the attention of Mr. Swanson and the rest of the faculty. A meeting to discuss the issue occurred last Friday, February 10th, in the all - school meeting room.

The faculty not only agreed that there wasn't much to do during these free periods, but also seemed determined to find a solution. The student body council and the faculty talked about different ideas for a long time. The faculty had noticed that some students don't like using their free periods for studying. Instead, they spend their time disrupting the students who want to study by being noisy in the library. By the end of the meeting, the faculty had decided to put a pool table and a ping pong table in our student lobby at the start of next semester.

I know some people will be concerned about getting their work done with these potential distractions, but I believe this will help us all in enjoying our time at school. I agree that it's important to complete our work but it is just as important to enjoy ourselves and to relax with our friends. School is already such a stressful place. It makes many students feel worried and anxious. We want our school to be a friendly place so that students want to come every day. Students should remember that this change will make the library a lot quieter. Because of this, the students who want to study will be able to do so in peace.

To all the students at Union High, I sincerely hope that you enjoy the new additions to our lobby. Hopefully, they will make our free periods a lot more relaxing. If you happen to have one of the same free periods as I do, then please challenge me to a game of pool!

In paragraph 2, the word disrupting is closest in meaning to ____.

Read the passage and choose the best answer to compete each of the statements that follow
The hippopotamus is the third largest land animal, smaller only than the elephant and the rhinoceros. Its name comes from two Greek words which mean "river horse". The long name of this animal is often shortened to the easier to handle term "hippo."
The hippo has a natural affinity for the water. It does not float on top of the water; instead, it can easily walk along the bottom of a body of water. The hippo commonly remains underwater for three to five minutes and has been known to stay under for up to half an hour before coming up for air.
In spite of its name, the hippo has relatively little in common with the horse and instead has a number of interesting similarities in common with the whale. When a hippo comes up after a stay at the bottom of a lake or river, it releases air through a blowhole, just like a whale. In addition, the hippo resembles the whale in that they both have thick layers of blubber for protection and they are almost completely hairless.

According to the passage, what is the maximum time that hippos have been known to stay underwater_______________

In the West, cartoons are used chiefly to make people laugh. The important feature of all these cartoons is the joke and the element of surprise which is contained. Even though it is very funny, a good cartoon is always based on close observation of a particular feature of life and usually has a serious purpose.
Cartoons in the West have been associated with political and social matters for many years. In wartime, for example, they proved to be an excellent way of spreading propaganda. Nowadays cartoons are often used to make short, sharp comments on politics and governments as well as on a variety of social matters. In this way, the modern cartoon has become a very powerful force in influencing people in Europe and tlie United States.
Unlike most American and European cartoons, however, many Chinese cartoon drawings in the past have also attempted to educate people, especially those who could not read and write. Such cartoons about the lives and sayings of great men in China have proved extremely useful in bringing education to illiterate and semi-literate people throughout China.
Confucius, Mencius and Laozi have all appeared in very interesting Stories presented in the form of cartoons. The cartoons themselves have thus served to illustrate the teachings of the Chinese sages in a very attractive way.
In this sense many Chinese cartoons are different from Western cartoons in so far as they do not depend chiefly on telling jokes. Often, there is nothing to laugh at when you see Chinese cartoons. This is not their primary aim. In addition to commenting on serious political and social matters, Chinese cartoons have aimed at spreading the traditional Chinese thoughts and culture as widely as possible among the people.
Today, however, Chinese cartoons have an added part to play in spreading knowledge.
They offer a very attractive and useful way of reaching people throughout the world, regardless of the particular country in which they live. Thus, through cartoons, the thoughts and teachings of the old Chinese philosophers and sages can now reach people who live in such countries as Britain, France, America, Japan, Malaysia or Australia and who are unfamiliar with the Chinese culture.
Until recently, the transfer of knowledge and culture has been overwhelmingly from the West to the East and not vice versa. By means of cartoons, however, publishing companies in Taiwan, Hong Kong and Singapore are now having success in correcting this imbalance between the East and the West.
Cartoons can overcome language barriers in all foreign countries. The vast increase in the popularity of these cartoons serves to illustrate the truth of Confucius's famous saying "One picture is worth a thousand words.”

Species that belong to an area are said to be native species. Typically, they have been part of a given biological landscape for a long period, and they are well adapted to the local environment and to the presence of other native species in the same general habitat. Exotic species are interlopers, foreign elements introduced intentionally or accidentally into new settings through human activities. In one context an introduced species may cause no obvious problems and may, over time, be regarded as being just as "natural" as any native species in the same habitat. In another context, exotics may seriously disrupt delicate ecological balances and create a cascade of unintended consequences. The worst of these unintended consequences arise when introduced species put native species in destruction by preying on them, altering their habitats, or out-competing them in the struggle for food resources. Although biological introductions have affected environments the world over, the most destructive, effects have occurred on islands, where introduced insects, cats, pigs, rats, mongooses, and other nonnative species have caused the grave endangerment or outright extinction of literally hundreds of species during the past 500 years. One of other reason to cause species extinction is overexploitation. This word refers to the utilization of a species at a rate that is likely to cause its extreme endangerment or outright extinction. Among many examples of severe overexploitation, the case of the great whales stands out in special relief. By the middle of the 20th century, unrestricted whaling had brought many species of whales to incredibly low population sizes. In response to public pressure, in 1982 a number of nations, including the USA, agreed to an international moratorium on whaling. As a direct result, some whale species which are thought to have been on extinction's doorstep 25 years ago have made amazing comebacks, such as grey whales in the western Pacific.  Others remain at great risk. Many other species, however, continue to suffer high rates of exploitation because of the trade in animal parts. Currently, the demand for animal parts is centered in several parts of Asia where there is a strong market for traditional medicines made from items like tiger bone and rhino horn.

Exotic species _______.

Reading to oneself is a modern activity which was almost unknown to the scholars of the classical and medieval worlds, while during the fifteenth century the term "reading" undoubtedly meant reading aloud. Only during thenineleenthcenturydid silent reading become commonplace.
One should be wary, however, of assuming that silent reading came about simply because reading aloud was a distraction to others. Examinations of factors related to the historical development of silent reading have revealed that it became the usual mode  of reading for most adults mainly because the tasks themselves changed in character.
The last century saw a steady gradual increase in literacy and thus in the number of readers. As the number of readers increased, the number of potential listeners declined and thus there was some reduction in the need to read aloud. As reading for the benefit of listeners grew less common, so came the flourishing of reading as a private activity in such public places as libraries, railway carriages and offices, where reading aloud would cause distraction to other readers.
Towards the end of the century, there was still considerable argument over whether books should be used for information or treated respectfully and over whether the reading of  materials such as newspapers was in some way mentally weakening. Indeed, this argument remains with us still in education. However, whatever its virtues, the old shared literacy  culture had gone and was replaced by the printed mass media on the one hand and by books and periodicals for a specialised readership on the other.
By the end of the twentieth century, students were being recommended to adopt attitudes to books and to use reading skills which were inappropriate, if not impossible, for the oral reader. The social, cultural and technological changes in the century had greatly altered what the term "reading" implied.

The phrase"oral reader" in the last paragraph mostly means a person who:

It's often said that we learn things at the wrong time. University students frequently do the minimum of work because they're crazy about a good social life instead. Children often scream before their piano practice because it’s so boring. They have to be given gold stars and medals to be persuaded to swim, or have to be bribed to take exams. But the story is different when you’re older.
Over the years, I've done my share of adult learning. At 30, I went to a college and did courses in History and English. It was an amazing experience. For starters, I was paying, so there was no reason to be late - I was the one frowning and drumming my fingers if the tutor was late, not the other way round. Indeed, if I could persuade him to linger for an extra five minutes, it was a bonus, not a nuisance. I wasn't frightened to ask questions, and homework was a pleasure not a pain. When I passed an exam, I had passed it for me and me alone, not for my parents or my teachers. The satisfaction I got was entirely personal
Some people fear going back to school because they worry that their brains have got rusty. But the joy is that, although some parts have rusted up, your brain has learnt all kinds of other things since you were young. It has learnt to think independently and flexibly and is much better at relating one thing to another. What you lose in the rusty department, you gain in the maturity department.
In some ways, age is a positive plus. For instance, when you're older, you get less frustrated. Experience has told you that, if you're calm and simply do something carefully again and again, eventually you'll get the hang of it. The confidence you have in other areas - from being able to drive a car, perhaps - means that if you can’t, say, build a chair instantly, you don't, like a child, want to destroy your first pathetic attempts. Maturity tells you that you will, with application, eventually get there.
I hated piano lessons at school, but I was good at music. And coming back to it, with a teacher who could explain why certain exercises were useful and with musical concepts that, at the age of ten, I could never grasp, was magical. Initially, I did feel a bit strange, thumping out a piece that I'd played for my school exams, with just as little comprehension of what the composer intended as I'd had all those years before. But soon, complex emotions that I never knew poured out from my fingers, and suddenly I could understand why practice makes perfect.

The phrase "get there" in paragraph 4 is closest in meaning to "     ".

The poaching crisis wiping out Africa's elephants is costing the continent's economies millions in lost tourism revenue, according to a new study. Researchers looked at visitor and elephant data across 25 countries, and modeled financial losses from fewer visitors in protected areas due to the illegal wildlife trade, which has caused elephant numbers to plummet by more than 100,000 in the last decade. (A)
The study team combined visitor numbers across 164 protected areas in 25 countries in forest and savannah elephants, and elephant population data from 2009 to 2013, to reach a “per elephant" value in terms of tourism income.
They concluded that Africa was most likely losing $26m in tourism revenue a year. (B) Around $9m of that is lost from tourists' direct spending, such as staying at hotels and buying crafts, with the rest through indirect value in the economy such as farmers and other suppliers supporting the tourist industry. 
The study, published in the journal Nature Communications, found that in most cases the revenue losses were higher than paying for stronger anti-poaching measures to keep elephant populations stable. (C) Dr. Robin Naidoo, the paper's lead author and , senior conservation wildlife scientist at WWF and his team found. In the case of central Africa's forest elephants, which are harder for tourists to see and therefore attract fewer visitors, the costs of protecting them exceed the benefits from tourism. Demand from south-east Asia has seen the price of ivory triple since 2009 and it is estimated that one elephant is killed every 15 minutes. (D) Corruption, a lack of resources, and, most importantly, increasingly sophisticated poachers have hamstrung African countries' efforts to stem the trade.
Naidoo said that the research was not suggesting economic issues should be the only consideration when protecting elephants, but framing the poaching crisis as a financial one could motivate African governments and communities.
“It gives an additional reason for some groups of people, who may not necessarily be motivated by intrinsic reasons for conversation, to engage with biodiversity conservation. It makes it clear to them that it's not just in the best interests of the world to conserve this stuff, but tangible reasons for a whole different group," he said.

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. 
Times are tough. The nightly news is filled with stories of people who have lost their jobs due to the economic crisis, or lost their homes in a fire or natural disaster. Have you ever seen people who have just endured an awful situation? Some focus on what they have lost, and this is easy to understand. But other people focus on what they did not lose, and they start thinking about a better future.
One good piece of advice to remember is that you cannot always control situations or other people. The only thing you can control is your own personal reaction to bad situations. Sometimes a situation may really be overwhelming. However, in many cases, you really can influence our own moods by the way you think about negative situations.
Imagine two families: Both have lost their homes and all their belongings in a devastating storm. One family cannot mask their grief. They feel that everything they hold dear has been destroyed. They cannot imagine how they will ever be able to replace things and start over again. Their normal life seems to have been completely lost. In contrast, a second family is crying with joy. All of the people in their family are unharmed and safe. This family is just happy that everyone has survived. This family is already trying to figure out how they can recover. You can’t really blame the first family for experiencing a very normal reaction to a terrible situation. However, the second family certainly seems to be better off. They are thinking about making progress rather than focusing on the tragic events. 
Though this scenario is extreme, everyone experiences setbacks that seem just awful at the time. This could be a job loss, illness, or problems with family members. Nobody gets through life without having some bad things happen. In these situations, try to focus on the steps you can take to remedy the situation, instead of how awful the setback is. By doing this, you will be laying the foundation for a better tomorrow. And you will not suffer as much pain today.
Actually, controlling how you feel and trying to maintain a positive attitude can help you through many tough situations. The bottom line is, no matter what the problem is, you are more likely to fix it if you can stay positive and work out a plan. Also, never be afraid to seek help when you need it. The advice of a friend, family member, or even a professional may be all it takes to get back on track. 
It may sound like a cliché. While a positive attitude may not be the answer to every problem, it can certainly give you an advantage in surviving most of life’s minor setbacks.

Which of the following could be the main idea of the passage?
A. Being optimistic is an effective way to get over bad situations.
B. Keeping positive or negative thoughts is the own choice of each person.
C. Positive thoughts are necessary conditions to be successful.
D. There seems to have more pessimists than optimists.

   Dinosaurs were reptiles that lived during a period of earth’s history called the Mesozoic Era, which is also known as the Age of Reptiles. The first dinosaurs appeared more than 200 million years ago. For many millions of years, they dominated the land with their huge size and strength. Then about 65 million years ago, they died out rather suddenly, never to re-emerge. The word “dinosauras” comes from two Greek words meaning “terrible lizard”. Dinosaurs were not lizards, but their appearance could be truly terrifying. The biggest ones weighed more than ten times as much as a mature elephant and nearly equalled the size of most modern-day whales. The famous kinds of dinosaurs, including the brontosaur and tyrannosaurus rex, reached 80 to 90 feet in length. Not all dinosaurs were giant, however, some were actually not larger than a chicken. Scientists still do not know what caused dinosaurs to disappear. One theory involves a change of the earth’s climate. It is believed that temperatures dropped significantly towards the end of the Cretaceous protection, it is possible that the climate became too chilly for dinosaurs. In contrast, other species having protection, such as the mammals and birds, were able to survive.

According to the passage, what is true about the size of dinosaurs?

Probably the most famous film commenting on the twentieth-century technology is Modem Times, made in 1936. Charlie Chaplin was motivated to make the film by a reporter who, while interviewing him, happened to describe the working conditions in industrial Detroit. Chaplin was told that healthy young farm boys were lured to the city to work on automotive assembly lines. Within four or five years, these young men's health was destroyed by the stress of work in the factories.
The film opens with a shot of a mass of sheep making their way down a crowded ramp. Abruptly, the film shifts to a scene of factory workers jostling one another on their way to a factory. However, the rather bitter note of criticism in the implied comparison is not sustained. It is replaced by a gentle note of satire. Chaplin prefers to entertain rather than lecture.
Scenes of factory interiors account for only about one-third of Modern Times, but they contain some of the most pointed social commentary as well as the most comic situations. No one who has seen the film can ever forget Chaplin vainly trying to keep pace with the fast-moving conveyor belt, almost losing his mind in the process. Another popular scene involves an automatic feeding machine brought to the assembly line so that workers need not interrupt their labor to eat. The feeding machine malfunctions, hurling food at Chaplin, who is strapped in his position on the assembly line and cannot escape. This serves to illustrate people's utter helplessness in the face of machines that are meant to serve their basic needs.
Clearly, Modern Times has its faults, but it remains the best film treating technology within  a social context. It does not offer a radical social message, but it does accurately reflect the sentiment of many who feel they are victims of an over - mechanized world

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: 
We are descendents of the ice age. Periods of glaciation have spanned the whole of human existence for the past 2 million years. The rapid melting of the continental glaciers at the end of the last ice age spurred one of the most dramatic climate changes in the history of the planet. During this interglacial time, people were caught up in a cataclysm of human accomplishment, including the development of agriculture and animal husbandry. Over the past few thousand years, the Earth’s climate has been extraordinarily beneficial, and humans have prospered exceedingly well under a benign atmosphere. Ice ages have dramatically affected life on Earth almost from the very beginning. It is even possible that life itself significantly changed the climate. All living organisms pull carbon dioxide out of the atmosphere and eventually store it in sedimentary rocks within the Earth’s crust. If too much carbon dioxide is lost, too much heat escapes out into the atmosphere. This can cause the Earth to cool enough for glacial ice to spread across the land. In general the reduction of the level of carbon dioxide in the atmosphere has been equalized by the input of carbon dioxide from such events as volcanic eruptions. Man, however, is upsetting the equation by burning fossil fuels and destroying tropical rain forests, both of which release stored carbon dioxide. This energizes the greenhouse effect and causes the Earth to warm. If the warming is significant enough, the polar ice caps eventually melt. The polar ice caps drive the atmospheric and oceanic circulation systems. Should the ice caps melt, warm tropical waters could circle the globe and make this a very warm, inhospitable planet. Over the past century, the global sea level has apparently risen upwards of 6 inches, mainly because of the melting of glacial ice. If present warming trends continue, the seas could rise as much as 6 feet by the next century. This could flood coastal cities and fertile river deltas, where half the human population lives. Delicate wetlands, where many marine species breed, also would be reclaimed by the sea. In addition, more frequent and severe storms would batter coastal areas, adding to the disaster of the higher seas. The continued melting of the great ice sheets in polar regions could cause massive amounts of ice to crash into the ocean. This would further raise the sea level and release more ice, which could more than double the area of sea ice and increase correspondingly the amount of sunlight reflected back into space. The cycle would then be complete as this could cause global temperatures to drop enough to initiate another ice age.

Which of the following does the author NOT mention as a consequence of a large rise in global sea level?

Choose the item among A, B, C or D that best answers the question about the passage: 

"Since the world has become industrialized, there has been an increase in the number of animal species that have either become extinct or have been near extinction. Bengal tigers, for instance, which once roamed the jungles in vast numbers, now number only about 2,300, and by the year 2025 their population is estimated to be down to zero. What is alarming about the case of the Bengal tiger is that this. extinction will have been caused almost entirely by poachers who, according to some sources, are not interested in material gain but in personal gratification. This is an example of the callousness that is part of what is causing the problem of extinction. Animals like the Bengal tiger, as well as other endangered species, are a valuable part of the world’s ecosystem. international laws protecting these animals must be enacted to ensure their survival, and the survival of our planet.
 Countries around the world have begun to deal with the problem in various ways. Some countries, in order to circumvent the problem, have allocated large amounts of land to animal reserves. They then change admission to help defray the costs of maintaining the parks, and they often must also depend on world organizations for support. With the money they get, they can invest in equipment and patrols to protect the animals. Another solution that is an attempt to stem the tide of animal extinction is an international boycott of Products made from endangered species. This seems fairly effective, but it will not, by itself, prevent animals from being hunted and killed."

Findings show that losing plants and animals is not only reducing our quality of life but actually endangering our very existence. We cut down rich rain-forests and replace them with one species plantations, such as pine and eucalyptus. We plough up meadows rich in different grasses and herbs and replace them with one grass, for instance, rye or wheat.

When a natural ecosystem is simplified the basic processes in the ecosystem are altered arid even damaged. Without their biodiversity, they are not able to serve as the natural cleaners of our planet. No longer are they able to absorb the carbon dioxide that is being produced in excess. The result is global warming, caused by the increase in the "greenhouse effect", and ultimately, or even sooner, there will be a change in the world's climate.
