Early peoples had no need of engineering works to supply their water. Hunters and nomads camped near natural sources of fresh water, and populations were so sparse that pollution of the water supply was not a serious problem. After community life developed and agricultural villages became urban centres, the problem of supplying water became important for inhabitants of a city, as well as for irrigation of the farms surrounding the city. Irrigation works were known in prehistoric times, and before 2000 BC the rulers of Babylonia and Egypt constructed systems of dams and canals to impound the flood waters of the Euphrates and Nile rivers, controlling floods and providing irrigation water throughout the dry season. Such irrigation canals also supplied water for domestic purposes. The first people to consider the sanitation of their water supply were the ancient Romans, who constructed a vast system of aqueducts to bring the clean waters of the Apennine Mountains into the city and built basins and filters along these mains to ensure the
clarity of the water. The construction of such extensive water-supply systems declined when the Roman Empire disintegrated, and for several centuries local springs and wells formed the main source of domestic and industrial water. The invention of the force pump in England in the middle of the 16th century greatly extended the possibilities of development of water-supply systems. In London, the first pumping waterworks was completed in 1562; it pumped river water to a reservoir about 37 m above the level of the River Thames and from the reservoir the water was distributed by gravity, through lead pipes, to buildings in the vicinity. Increased per-capita demand has coincided with water shortages in many countries. Southeast England, for example, receives only 14 per cent of Britain's rainfall, has 30 per cent of its population, and has experienced declining winter rainfall since the 1980s.
In recent years a great deal of interest has been shown in the conversion of seawater to fresh water to provide drinking water for very dry areas, such as the Middle East. Several different processes, including distillation, electrodialysis, reverse osmosis, and direct-freeze evaporation, have been developed for this purpose. Some of these processes have been used in large facilities in the United States. Although these processes are successful, the cost of treating seawater is much higher than that for treating fresh water.

Which of the following is NOT mentioned as a process of conversing seawater to freshwater?

Wolfgang Amadeus Mozart

Wolfgang Amadeus Mozart’s was the only surviving son of Leopold and Maria Pertl Mozart. Leopold was a successful composer, violinist, and assistant concertmaster at the Salzburg court. Wolfgang's mother, a constantly ill housewife, was born to a middle-class family of local community leaders. His only sister was Maria Anna. With their father’s encouragement and guidance, they both were introduced to music at an early age. Leopold started Anna on the keyboard when she was seven, as three-year-old Wolfgang looked on. Mimicking her playing, Wolfgang quickly began to show a strong understanding of chords, tonality, and tempo. Soon, he too was being tutored by his father.

Leopold was a devoted and task-oriented teacher to both his children. He made the lessons fun, but also insisted on a strong work ethic and perfection. Fortunately, both children excelled well in these areas. Recognizing their special talents, Leopold contributed much of his time to their education in music as well as other subjects. Wolfgang soon showed signs of excelling beyond his father's teachings with an early composition at age five and demonstrating outstanding ability on harpsichord and the violin. He would soon go onto play the piano, organ and viola.

The word outstanding is closest in meaning to ______.

Lady Liberty
New York City is undoubtedly one of the most famous cities in the world. There are several landmarks such as the Empire State Building, Broadway, and Times Square which have come to symbolize the Big Apple. Although these landmarks are all impressive, nothing captures the true spirit of the city like a gigantic, greenish sculpture that stands proudly in New York Harbour: the famed Statue of Liberty. The Statue of Liberty was created as a special gift to the US by French sculptor Frédéric Auguste Bartholdi. It was designed to represent the friendship between the French and American people, two close allies that fought against the British during the American Revolutionary War. Initially, Bartholdi anticipated that he would be able to finish the statue by 1876. The project was conceived as a joint venture. The French would fund and create the statue and send it to the US, while Americans would provide a location and build a pedestal to display it on. The initial completion date would eventually be delayed, however, due to financial issues with both nations. Bartholdi had some technical issues to deal with as well. He had never designed an enormous copper structure of this size and he required some expert assistance. Therefore, Bartholdi recruited Alexandre Gustave Eiffel the designer of the Eiffel Tower to help him. After nine years of hard work, the 151-foot, 22-ton statue was eventually completed and presented to the American Ambassador in France. It then had to he taken apart and separated into crates before being delivered to the US. It took another two years before Americans were able to raise enough public funds to build the pedestal that she would stand on. But the task was finally completed and the Statue of Liberty was assembled and dedicated on October 28, 1886. Over the years, the symbolism of the Statue of Liberty continued to glow more and more important until it became a key symbol of the entire nation. During the late 19th and early 20th century, it was the first landmark that waves of immigrants saw as they sailed into Ellis island. The sight of this symbol of freedom gave them hope and inspiration that their life would be better in their new country. Even today, people from all around the world see it as a powerful symbol of the American democracy.
1. What reasons does the passage give for why the Statue of Liberty is special?

Read the following passage and choose the best answer (A, B, C, D):
One of the major problems in the art world is how to distinguish and promote an artist. In effect, a market must be created for an artist to be successful. The practice of signing and numbering individual prints was introduced by James Abbott McNeill Whistler, the nineteenth-century artist best known for the painting of his mother, called "Arrangement in Grey and Black", but known to most of US as "Whistler's Mother". Whistler's brother-in- law, Sir Francis Seymour Haden, a less well-known artist, had speculated that collectors might find prints more attractive if they knew that they were only a limited number of copies produced. By signing the work in pencil, an artist could guarantee and personalize each print. As soon as Whistler and Haden began the practice of signing and numbering their prints, their work began to increase in value. When other artists noticed that the signed prints commanded higher prices, they began copying the procedure. Although most prints are signed on the right-hand side in the margin below the image, the placement of the signature is a matter of personal choice. Indeed, prints have been signed within the image, in any of the margins, or even on the reverse side of the print. Wherever the artist elects to sign it, a signed print is still valued above an unsigned one, even in the same edition.

Mark the letter A, B, C, or D on your answer sheet to indicate the undelined part that needs correction in each of the following questions:
The cause of tooth decay is acid, which is produced by bacteria in the mouth. The acid removes minerals from tooth enamel, allowing tooth decay to begin; the saliva in your mouth encourages remineralization and neutralizes the acid. The rate at which bacteria in the mouth produce acid depends on the amount of plaque on the teeth, the composition of the microbial flora, and whether the bacteria of the plaque have been "primed" by frequent exposure to sugar. To keep your teeth healthy, a regular dental hygiene program should be followed.
Removing plaque with a toothbrush and dental floss temporarily reduces the numbers of bacteria in the mouth and thus reduces tooth decay. It also makes the surfaces of the teeth more accessible, enabling saliva to neutralize acid and remineralize lesions. If fluoride is present in drinking water when teeth are forming, some fluoride is incorporated into the enamel of the teeth, making them more resistant to attack by acid. Fluoride toothpaste seems to act in another way, by promoting the remineralization of early carious lesions.
In addition to a regular dental hygiene program, a good way to keep your teeth healthy is to reduce your intake of sweet food. The least cavity-causing way to eat sweets is to have them with meals and not between. The number of times you eat sweets rather than the total amount determines how much harmful acid the bacteria in your saliva produce. But the amount of sweets influences the quality of your saliva. Avoid, if you can, sticky sweets that stay in your mouth a long time. Also try to brush and floss your teeth after eating sugary foods. Even rinsing your mouth with water is effective. Whenever possible, eat foods with fiber, such as raw carrot sticks, apples, celery sticks, etc., that scrape off plaque, acting as a toothbrush. Cavities can be greatly reduced if these rules are followed when eating sweets.

According to the passage, all of the following statements about plaque are true EXCEPT     .

Frozen Fitness
A man stands over a bathtub that is filled with ice. Although it is the middle of winter, he slowly slides into the tub and submerges his body underneath the water. Within seconds, he begins to shiver, but after a few minutes he is able to settle down. Despite the temperature, he will remain in the tub for the next 30 minutes. He is taking advantage of cold thermogenesis, a growing trend that could improve people’s health. Thermogenesis is an internal process that mammals undergo to generate heat when they are subjected to cold temperatures. In modern society, humans rarely requires this ability because we have heated homes and offices during the winter season. Recent studies, however, indicate that by doing so we could be missing out on some wonderful health benefits. Being subjected to cold temperatures regularly has been shown to boost men’s testosterone levels. It also boosts metabolism, which allows people to burn fat more efficiently. Some people have reported that cold thermogenesis also provides a mental lift once you have overcome the initial shock of the cold water. The positive effects of thermogenesis were known before, but it only started to become popular after the 2008 Olympics. One man who helped spark this craze was Ray Cronise, a NASA scientist and entrepreneur. He was reading an article that reported Michael Phelps ate 12,000 calories per day while training. The calories were so high that led him to believe that something else besides exercise was helping Phelps to stay thin and muscular: the icy water in the swimming pool. So he conducted his own experiment by drinking several glasses of ice water and exposing himself to cold water. After six weeks of this regiment, he had lost 30 pounds. There are several routines that a person can adopt if they are interested in starting their own thermogenesis routine. One method is ice baths. This method may be a bit too drastic for average people though. Instead, people may want to begin by dunking their face in cold water for a few seconds, and then gradually increase the time. Next, they can progress to cold showers and baths before moving on ice baths. An even more convenient way is to place an ice packet on the back of your neck for 15 to 20 minutes every evening. Although these methods may be extreme, many are willing to give them a go to improve their health

Twitter: 140 Characters to Express Yourself
At the start of the social media revolution, Facebook quickly became the most popular site for sharing information with others. However, it is not the only service that people can use to express themselves. Those who believe in the old saying that “more is less” may want to check out Twitter. Part of Twitter’s appeal is that it limits users to 140 characters whenever they update their status. This forces people to quickly “get to the point” when they are communicating. Twitter is a microblogging service that was created by four American programmers in 2006. The founders chose the name Twitter because the word has two definitions: “a short burst of information” and “the sound that little birds make”, both of which fit the description of what their service provides. In fact, some people have even labeled Twitter the “SMS of the Internet”. Twitter is not just about words though. Users can also share videos and pictures. Another thing which truly sets Twitter apart from its competition is the hashtag. Hashtags are a special way of labeling and classifying information. They help people interested in a subject to find related posts and content. For example, some interested in sports could simply search for hashtag sports and they would find all messages tagged in this manner. Twitter has also allowed people to easily connect with others who they would have never had access to in the past. This has enabled fans to interact with their favourite celebrities by following their Twitter updates and sending them direct messages. Of course, there is no guarantee that the famous person will respond, as the celebrities may receive thousands of messages each day. However, there have been some pretty stunning interactions. In 2011, singer Justin Timberlake made headlines when he accepted an invitation from a female soldier to attend a Marine Corps ball. In return, many celebrities find it gratifying to know some of their supporters more closely. However, there is a dark side to Twitter conversations: Some people who don’t think before sending out tweets that can cause outrage by making inappropriate or insensitive remarks. In November 2013, Twitter went public on the New York Stock Exchange. The added investments should allow the company to do some incredible things in the near future

Durable Ceramic Beauty
Inside an art and craft workshop, a young woman sits in front of a pottery wheel. The machine contains a large lump of clay which she molds into the shape of an elaborate bowl. Later, when she is satisfied with its appearance, it will be baked in an oven until it solidifies. Then she adds decorative paints to add some style. In the end, this ceramic pot will be both a handy utility for eating as well as a work of art. Humans have been working with ceramics for about 30,000 years, making it one of the oldest industries on the planet. In ancient times, ceramics enabled humans to make containers to store food and drinks, as well as bricks for buildings, but as time went on, people found other uses for this prehistoric technology. Techniques were added to give these products more eye-catching designs. Objects were often coated with glaze, so they would be smoother and more pleasant to touch. This helped to transform these practical items into works of art. People would pay large amounts of money for pieces of ceramic art and use them to decorate their homes. In modern times, architects and inventors discovered that ceramic offered the perfect balance between beauty and durability, and started using it in their products as well. Ceramics have found a home in the world of automobiles as they are used to produce several products. They are often used to make brake discs, engines, and other parts because ceramics are able to withstand extremely hot temperatures. Ceramics also play a part in the world of medicine, as their flexibility and strength are perfect for creating sturdy dental implants. Other doctors are using them to replace damaged bones because they are able to bond with tissues in the body without causing adverse reactions. In many kitchens today, you will also find ceramic knives. Once they are produced, the hard edges of these blades rarely need to be sharpened. Unlike metal knives, they won’t rust when exposed to difficult conditions. Ceramics also help to make it possible for humans to travel into space. Space shuttles are designed with ceramic tiles because they are one of the few materials that can stand the extreme heat when reentering the Earth’s atmosphere, plus they don’t wear out easily. With so many useful applications, it is hard to deny that ceramic technology is out of this world.

The Advancing Development of Artificial Limbs
It wasn’t very long ago that losing a limb automatically meant a drastic drop in the quality of a person’s life. Thanks to the wonders of modern science, people now are recovering from all sorts of horrendous injuries that let them disabled. The reason they are able to do so is remarkable advances made in the field of artificial limbs. Doctors have been creating prosthetic limbs for their patients dating back to ancient Greece. For most of history, however, these replacements were mainly for cosmetic purposes. Pirates, knights, loot soldiers that lost their limbs in battle would get them, so they wouldn’t lose face when returning to society. It wasn’t until the mid-19th century that doctors were able to perform surgeries to reliably attach limbs to people’s bodies and amputate limbs without causing serious infection. Modern artificial limbs represent a tremendous leap forward in terms of form and function. Today’s limbs are far more durable and can withstand a lot more wear and tear. An amazing example of how far artificial limbs have progressed is the Flex-Foot Cheetah. Made from carbon fiber, it is able to store energy as the person moves, which enables the wearer to run and jump. The technology is so good that approximately 90 percent of all Special Olympic amputees use them in competition. Meanwhile, the Bebionic3 has emerged as the most advanced prosthetic arm available. It has been nicknamed “The Terminator” because it is similar to Arnold Schwarzenegger’s mechanical limbs in the famous blockbuster film. The Bebionic3 can perform a multitude of tasks including writing, tying a shoelace, lifting heavy objects, and even pouring a beer. Wearers simply push a button on the base of the arm and the Bebionic3 will work its magic. In September 2013, scientists took another giant leap forward when they successfully fitted a patient with an artificial leg that can be controlled by thought. Two of the patient’s nerves were attached to his hamstring muscle. These nerves then interact with sensors inside the artificial leg. Sensors will then transmit these messages to a computer which will follow through on his instructions. Therefore, if the patient wants to stretch out his leg, the computer will understand this command and send a message to the limb and instruct it to do so. If artificial limb technology keeps advancing like this, losing a limb may not be such a big deal.
4. Which of the following best matches the meaning of the word “multitude” in paragraph 4?

Though called by sweet-sounding names like Firinga or Katrina, tropical cyclones are huge rotating storms 200 to 2,000 kilometers wide with winds that blow at speeds of more than 100 kilometers per hour (kph). Weather professionals know them as tropical cyclones, but they are called hurricanes in the Caribbean Sea, typhoons in the Pacific Ocean, and cyclones in the Indian Ocean. They occur in both the northern and southern hemispheres. Large ones have destroyed cities and killed hundreds of thousands of people.

Tropical cyclones begin over water that is warmer than 27 degrees Celsius (80 degrees Fahrenheit) slightly north or south of the earth’s equator. Warm, humid air full of water vapor moves upward. The earth's rotation causes the growing storm to start to rotate around its center (called the eye). At the certain height, the water vapor condenses, changing to liquid and releasing heat. The heat draws more air and water vapor upward, creating a cycle as air and water vapor rise and liquid water falls. If the cycle speeds up until winds reach 118 kilometers per hour, the storm qualifies as a tropical cyclone.

Most deaths in tropical cyclones are caused by storm surge. This is a rise in sea level, sometimes seven meters or more, caused by the storm pushing against the ocean's surface. Storm surge was to blame for the flooding of New Orleans in 2005. The storm surge of Cyclone Nargis in 2008 in Myanmar pushed seawater nearly four meters deep some 40 kilometers inland, resulting in many deaths.

 According to the passage, a storm surge is________.

Clean, Convenient, and Cheap
Big cities like New York and London have a lot of great things. They have museums, parks, shopping centres, and a huge variety of restaurants. However, there are a lot of annoying things in big cities. The most common problems are air pollution and noise. Traffic is the main cause of air pollution and noise. For example, drivers in New York are famous for honking their horns and shouting. That noise drives many visitors crazy – it even drives a lot of the locals crazy, too. Other big cities have similar problems with their traffic. City governments have a lot of pressure to solve these problems. The most common solution is public transportation. Public transportation is a form of travel provided by the government. For example, New York’s biggest form of public transportation is the subway. Public transportation helps reduce these problems, but it is not enough. Another solution is bicycle sharing. This is a system that provides cheap bicycles. In cities that have bicycle sharing programmes, there are spots that have parked public bikes. People borrow the bikes and use them. They can _drop off_ the bike at the same spot where they borrowed it, or they can drop it off at another spot. Bicycle sharing programmes are different in each city. In some cities, the bikes are completely free. They are not even locked. In other cities, you have to pay a small deposit. You get the deposit back when you return the bike. In still other cities, you need to have a membership with the bicycle sharing programme. Once you have a membership with the bicycle sharing programme, you can use a bike at any time you want. Bicycle sharing is hugely popular all over the world. People love this system because it is cheap, clean, and easy to use. There are bicycle sharing systems in dozens of countries and hundreds of cities. In total, there are more than 530 bicycle sharing systems around the world, and that number is going up all the time.

Read an article about Elizabeth Taylor and choose the best answer.

Elizabeth Rosemond Taylor was born on February 27, 1932, in London, England. One of film's most celebrated stars, Elizabeth Taylor has fashioned a career that's covered more than six decades, accepting roles that have not only showcased her beauty, but her ability to take on emotionally charged characters.

Taylor's American parents, both art dealers, were residing in London when she was born. Soon after the outbreak of World War II, the Taylors returned to the United States and settled into their new life in Los Angeles.

Performance was in Taylor's blood. Her mother had worked as an actress until she married. At the age of 3, the young Taylor started dancing, and eventually gave a recital for Princesses Elizabeth and Margaret. Not long after relocating to California a family friend suggested the Taylors' daughter take a screen test.

She soon signed a contract with Universal Studios, and made her screen debut at the age of 10 in There's One Born Every Minute (1942). She followed that up with a bigger role in Lassie Come Home (1943) and later The White Cliffs of Dover (1944).

Her breakout role, however, came in 1944 with National Velvet, in a role Elizabeth Taylor spent four months working to get. The film subsequently turned out to be a huge hit that pulled in more than $4 million and made the 12-year-old actress a huge star.

Her role in National Velvet ____________________.
