In full computer animation, complex mathematical formulas are used to produce the final sequences of pictures. These formulas operate on extensive databases of numbers that defines the objects in the pictures as they exist in mathematical space. The database consists of endpoints, and color and intensity information. Highly trained professionals are needed to produce such effects because animation that obtains high degrees of realism involves computer techniques from three-dimensional transformation, shading, and curvatures.

   High-tech computer animation for film involves very expensive computer systems along with special color terminals or frame buffers. The frame buffer is nothing more than a giant image memory for viewing a single frame. It temporarily holds the image for display on the screen.

According to the passage, the positions and colors of the figures in high-tech animation are determined by

The major problem is that the planet appears to be warming up. According to some experts, this warming process, known as global warming, is occurring at a rate unprecedented in the last 10,000 years. The implications for the planet are very serious. Rising global temperatures could give rise to such ecological disasters as extremely high increases in the incidence of flooding and of droughts. These in turn could have a harmful effect on agriculture.

   It is thought that this unusual warming of the Earth has been caused by so-called greenhouse gases, such as carbon dioxide, being emitted into the atmosphere by car engines and modern industrial processes, for example. Such gases not only add to the pollution of the atmosphere, but also create a greenhouse effect, by which the heat of the sun is trapped. This leads to the warming up of the planet.

   Politicians are also concerned about climate change and there are now regular summits on the subject, attended by representatives from around 180 of the world’s industrialized countries. Of these summits, the most important took place in Kyotoin Japanin 1997. There it was agreed that the most industrialized countries would try to reduce the volume of greenhouse gas emissions and were given targets for this reduction of emissions.

According to the passage, agriculture could ____.

The invention of the mobile phone has undoubtedly revolutionized the way people communicate and influenced every aspect of our lives. The issue is whether this technological innovation has done more harm than good. In order to (1)______ the question, we must first turn to the type of consumer. Presumably, most parents buy mobile phones for their teenagers to track their whereabouts and ensure their safety. We can also assume that most teenagers want mobile phones to avoid missing out (2)______ social contact. In this context, the advantages are clear. However, we cannot deny the fact that text messages have been used by bullies to intimidate fellow students. There is also (3)______ evidence that texting has affected literacy skills. The ubiquitous use of the mobile phone has, (4)______ question, affected adult consumers, too. What employee, on the way home from work, would be reluctant to answer a call from their boss? Apparently, only 18% of us, according to a recent survey, are willing to switch off our mobile phones once we’ve left the office. Admittedly, mobile phones can be intrusive but there are obvious benefits to possessing one. Personally speaking, they are invaluable when it comes to making social or business arrangements at short (5)______. According to a recent survey, they also provide their owners with a sense of security in emergency situations. In conclusion, mobile phones do have their drawbacks, but these are outweighed by the benefits. I would argue that it is not the tool that chooses its purpose, but the user.

The search for alternative sources of energy has led in various directions. Many communities are burning garbage and other biological waste products to produce electricity- Converting waste products to gases or oil is also an efficient way to dispose of wastes. Experimental work is being done to derive synthetic fuels from coal, oil shale, and coal tars. But to date, that process has proven expensive. Other experiments are underway to harness power with giant windmills. Geothermal power is also being tested. Some experts expect utility companies to revive hydroelectric power derived from streams and rivers. Fifty years ago hydroelectric power provided one third of the electricity used in the United States, but to day it supplies only 4 percent. The oceans are another potential source of energy. Scientists are studying ways to convert the energy of ocean currents, tides, and waves to electricity. Experiments are also underway to make use of temperature differences in ocean water to produce energy.

In the second paragraph, the phrase “synthetic fuels” could best be replaced by which of the following

 The American type of football was developed in the 19th century from soccer and rugby football. Played by professionals, amateurs, college and high school students, or young children, football in American is one of the most popular sports besides basketball and baseball. It attracts millions of fans each fall and people are very supportive of their favourite teams. The football playing field of today is rectangular in shape and measures 100 yards long and 53.5 yards wide. White lines are painted on the playing field to mark off the distances to the end zone. The games is divided into four quarters, each fifteen minutes long. The first two quarters are known as the first half. There is a rest period between two halves which usually last about fifteen minutes. Each team has eleven players. Each team has offensive players who play when the team has possession of the ball and defensive players who play when the other team has the possession of the ball. Because of the body contact players have during the game, helmets are worn to protect their head and face area, whereas pads are worn to protect the shoulders, arms, and legs.

 Playing American football is the most similar to playing

Question 43....................

   The countryside of Britain is well known for its beauty and many contrasts: its bare mountains and moorland, its lakes, rivers and woods, and its long, often wild coastline. Many of the most beautiful areas are national parks and are protected from development. When British people think of the countryside they think of farmland, as well as open spaces. They imagine cows or sheep in green fields enclosed by hedges or stone walls, and fields of wheat and barley. Most farmland is privately owned but is crossed by a network of public footpaths.

   Many people associate the countryside with peace and relaxation. They spend their free time walking or cycling there, or go to the country for a picnic or a pub lunch. In summer people go to fruit farms and pick strawberries and other fruit. Only a few people who live in the country work on farms. Many commute to work in towns. Many others dream of living in the country, where they believe they would have a better and healthier lifestyle

We can see from the passage that in the countryside of Britain ______.

 London was strange and disappointing. There was no gold on the pavements, as the stories in Jaimaica had indicated. The roads were busy, the buildings were grey and dull, with many tall, high-rise blocks. It was totally unlike Jamaica, the houses all small and packed close together. In my grandmother's house I had a big bedroom, here I had to share.

   Then came the biggest shock: snow. While flakes came out of the sky and Dad smiled, pointed and said: "That's snow!" I rushed outside, looked up and opened my mouth to let the flakes drop in. The snow settled on my tongue and it was so cold that I cried. My toes lost all feeling. As my shoes and socks got wet and frozen, there came an excruciating pain and I cried with the intensity of it. I didn't know what was happening to me.

The word "excruciating" in the last paragraph means ________

Thanksgiving is celebrated in the US on the fourth Thursday in November. For many Americans it is the most important holiday apart from Christmas. Schools, offices and most businesses close for Thanksgiving, and many people make the whole weekend a vacation.

   Thanksgiving is associated with the time when Europeans first came to North America. In 1620 the ship the Mayflowers arrived, bringing about 150 people who today are usually called Pilgrims. They arrived at the beginning of a very hard winter and could not find enough to eat, so many of them died. But in the following summer Native Americans showed them what foods were safe to eat, so that they could save food for the next winter. They held a big celebration to thank God and the Native Americans for the fact that they had survived.

   Today people celebrate Thanksgiving to remember these early days. The most important part of the celebration is a traditional dinner with foods that come from North America. The meal includes turkey, sweet potatoes (also called yams) and cranberries, which are made into a kind of sauce or jelly. The turkey is filled with stuffing or dressing, and many families have their own special recipe. Dessert is pumpkin made into a pie.

All of the following statements are mentioned EXCEPT ______.

 In the 1960s, The Beatles were probably the most famous pop group in the whole world. Since then, there have been a great many groups that have achieved enormous fame, so it is perhaps difficult now to imagine how sensational The Beatles were at that time. They were four boys from the north of England and none of them had any training in music. They started by performing and recording songs by black Americans and they had some success with these songs. Then they started writing their own songs and that was when they became really popular. The Beatles changed pop music. They were the first pop group to achieve great success from songs they had written themselves. After that it became common for groups and singers to write their own songs. The Beatles did not have a long career. Their first hit record was in 1963 and they split up in 1970. They stopped doing live performances in 1966 because it had become too dangerous for them - their fans were so excited that they surrounded them and tried to take their clothes as souvenirs! However, today some of their songs remain as famous as they were when they first came out. Throughout the world, many people can sing part of a Beatles song if you ask them.

The passage is mainly about __________

 In addition to its biological consequences, extinction poses a moral dilemma for humans, the only species capable of saving the others. The presence of humans on the planet has affected all other life forms, particularly plants and animals. Human lifestyles have proven to be incompatible with the survival of some other species. Purposeful efforts have been made to eliminate animals that prey on people, livestock, crops, or pose any threat to human livelihoods. Some wild animals have been decimated by human desire for meat, hides, fur, or other body parts with commercial value. Likewise, demand for land, water, and other natural resources has left many wild plants and animals with little to no suitable habitat. Humans have also affected nature by introducing non-native species to local areas and producing pollutants having a negative impact on the environment. The combination of these human-related effects and natural obstacles such as disease or low birthrates has proven to be too much for some species to overcome. They have no chance of survival without human help.

   As a result, societies have difficult choices to make about the amount of effort and money they are willing to spend to save imperiled species. Will people accept limits on their property rights, recreational activities, and means of livelihood to save a plant or an animal? Should saving such popular species as whales and dolphins take priority over saving obscure, annoying, or fearful species? Is it the responsibility of humans to save every kind of life form from disappearing, or is extinction an inevitable part of nature, in which the strong survive and the weak perish? These are some difficult questions that people face as they ponder the fate of other species living on this planet.

 In paragraph 2, non-native species are mentioned as ______.

  A rather surprising geographical feature of Antarctica is that a huge freshwater lake, one of the world’s largest and deepest, lies hidden there under four kilometers of ice. Now known as Lake Vostok, this huge body of water is located under the ice block that comprises Antarctica. The lake is able to exist in its unfrozen state beneath this block of ice because its waters are warmed by geothermal heat from the earth’s core. The thick glacier above Lake Vostok actually insulates it from the frigid temperatures on the surface.

   The lake was first discovered in the 1970s while a research team was conducting an aerial survey of the area. Radio waves from the survey equipment penetrated the ice and revealed a body of water of indeterminate size. It was not until much more recently that data collected by satellite made scientists aware of the tremendous size of the lake; the satellite-borne radar detected an extremely flat region where the ice remains level because it is floating on the water of the lake.

   The discovery of such a huge freshwater lake trapped under Antarctica is of interest to the scientific community because of the potential that the lake contains ancient microbes that have survived for thousands of years, unaffected by factors such as nuclear fallout and elevated ultraviolet light that have affected organisms in more exposed areas.

Perhaps it was because he was a handsome, red-haired country boy, the son of a poor miner from Oklahoma. His career, from the lead mines of the West to the heights of success and fame, was a fairy-tale version of the American dream. Or perhaps it was because America always loves a “natural”: a person who wins without seeming to try, whose talent appears to come from an inner grace. That was Mickey Mantle.

   But like many celebrities, Mickey Mantle had a private life that was full of problems. He played without complaint despite constant pain from injuries. He lived to fulfill his father’s dreams and drank to forget his father’s early death.

   It was a terrible addiction that finally destroyed his body. It gave him cirrhosis of the liver and accelerated the advance of liver cancer. Even when Mickey Mantle had turned away from his old life and warned young people not to follow his example, the destructive process could not be stopped. Despite a liver transplant operation that had all those who loved and admired him hoping for a recovery, Mickey Mantle died of cancer at the age of 63.

Which of the following is mentioned as the main cause of the destruction of Mantle’s body?

In American, although most men still do less housework than their wives, that gap has been halved since the 1960s. Today, 41 per cent of couples say they share childcare equally, compared with 25 percent in 1985. Men's greater involvement at home is good for their relationships with their spouses, and also good for their children. Hands-on fathers make better parents than men who let their wives do all the nurturing and childcare. They raise sons who are more expressive and daughters who are more likely to do well in school - especially in math and science.

In 1900, life expectancy in the United States was 47 years, and only four per cent of the population was 65 or older. Today, life expectancy is 76 years, and by 2025, it is estimated about 20 per cent of the U.S. population will be 65 or older. For the first time, a generation of adults must plan for the needs of both their parents and their children. Most Americans are responding with remarkable grace. One in four households gives the equivalent of a full day a week or more in unpaid care to an aging relative, and more than half say they expect to do so in the next 10 years. Older people are less likely to be impoverished or incapacitated by illness than in the past, and have more opportunity to develop a relationship with their grandchildren.

Even some of the choices that worry people the most are turning out to be manageable. Divorce rates are likely to remain high, and in many cases marital breakdown causes serious problems for both adults and kids. Yet when parents minimize conflict, family bonds can be maintained. And many families are doing this. More non-custodial parents are staying in touch with their children. Child-support receipts are rising. A lower proportion of children from divorced families are exhibiting problems than in earlier decades. And stepfamilies are learning to maximize children's access to supportive adults rather than cutting them off from one side of the famil

Nowadays, ____ of men help take care of children.

Gardening also takes place in non-residential green areas, such as parks, public or semi-public gardens amusement and theme parks, along transportation corridors, and around tourist attractions and hotels. In these situations, a staff of gardeners or groundskeepers maintains the gardens.

Indoor gardening is concerned with the growing of houseplants within a residence or building, in a conservatory, or in a greenhouse. Indoor gardens are sometimes incorporated as part of air conditioning or heating systems.

Water gardening is concerned with growing plants adapted to pools and ponds. Bog gardens are also considered a type of water garden. These all require special conditions and considerations. A simple water garden may consist solely of a tub containing the water and plant.

Who maintains the public gardens ?
