Clean and Popular
Wind power is a very clean source of energy. This is how wind power works. Wind makes windmills spin. When the windmills spin, they make electricity. Then we can use the electricity. Many people think that wind power is new, but that is not true. For thousands of years, people have used wind to sail boats and move water. We still do those things today, but these days we mostly use wind power to make electricity. Wind power is a very popular source of energy. Most people think that should use it more and more. First of all, it is clean. Windmills don’t pollute the environment at all. Second, we can use wind power forever. After all, we will always have wind. In addition, wind power is cheap, and it is getting even cheaper. A lot of people don’t understand wind power very well. They believe that there are problems with wind power, but many of those problems are not real. For example, some people say that windmills are dangerous for birds. That used to be true, but it isn’t true anymore. Old windmills killed birds because they spun very fast. New windmills spin slowly, and they aren’t dangerous for birds. However, there are real problems with windmills. One problem is that many people think windmills are very ugly. This is a problem for some people, because windmills are often in very pretty areas. Besides, wind doesn’t blow all the time, so we can’t use wind power all year round. Finally, windmills are noisy. Wind power is becoming more and more common. Right now, more than 80 countries use wind power. About 2.5 percent of the world’s power comes from the wind. For some countries, that number is a lot higher. Wind power gives Denmark more than 25 percent of its electricity.

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:
Animals have an intuitive awareness of quantities. They know without analysis the difference between a number of objects and a smaller number. In his book "The Natural History of Selboure" (1786), the naturalist Gilbert White tells how he surreptitiously removed one egg a day from a plover's nest, and how the mother laid another egg each day to make up for the missing one. He noted that other species of birds ignore the absence of a single egg but abandon their nest if more than one egg has been removed. It has also been noted by naturalists that a certain type of wasp always provides five - never four, never six - caterpillars for each of their eggs so that their young have something to eat when the eggs hatch. Research has also shown that both mice and pigeons can be taught to distinguish between odd and even numbers of food pieces.
These and similar accounts have led some people to infer that creatures other than humans can actually count. They also point to dogs that have been taught to respond to numerical questions with the correct number of banks, or to horses that seem to solve arithmetic problems by stomping their hooves the proper number of times.
Animals respond to quantities only when they are connected to survival as a species - as in the case of the eggs - or survival as individuals - as in the case of food. There is no transfer to other situations of from concrete reality to the abstract notion of numbers. Animals can "count" only when the objects are present and only when the numbers involved are small - not more than seven or eight. In lab experiments, animals trained to "count" one kind of object were unable to count any other type. The object, not the numbers, are what interest them. Animals' admittedly remarkable achievements simply do not amount to evidence of counting, nor do they reveal more than innate instincts, refined by the genes of successive generations, or the results of clever, careful conditioning by trainers.

According to information in the passage, which of the following is LEAST likely to occur as a result of animals' intuitive awareness of quantities?

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.

One of the causes of water shortages in South-east England is     .

Incredible Shrinking Microchips
There is a popular old saying that “bigger is better”. Although this may be true in some regards, the exact opposite often applies in technology. As electronic components get smaller, it allows companies to manufacture tinier devices with more features. Thus began the never-ending quest to create the smallest microchips on the planet. Yet as these vital electronic components get smaller, they are also getting stronger and clever inventors are finding new ways in which to use them to do incredible things. Currently, the biggest limitation microchip producers face when trying to reduce chips’ size is the copper wires that provide electrical current throughout the chip. Although they can be made smaller, this can cause a whole host of problems such as melting and overheating. Thanks to the work of a few scientists from the UK though, this problem may soon be a thing of the past. Their solution is getting rid of the copper wiring altogether and using carbon nanotubes instead. Not only would this allow for smaller sizes but it would also increase the power that microchips can generate. In the end, this would translate into smaller and more powerful devices much to the delight of consumers all over the world. Corporate powerhouse Intel® has announced plans to create a line of tiny, low power chips that can be used in bracelets, smart watches, and other tiny devices. The chips will be called Intel® Quark, and they are being designed primarily to fit in biomedical devices. A key selling point to biomedical technology is that the devices have to be nonintrusive because people don’t want to carry around heavy equipment to monitor their health. If they can do this, Intel® will likely find several tablet and smartphone manufacturers who are willing to corporate Quark microchips into their devices. In a somewhat unusual project, researchers are working on a special microchip that will serve as miniature human organs in experiments. These “organ” chips could be used to test different medicines and study diseases. If realized, the technology could put an end to the use of lab mice and other animals for testing. Everyone from the largest pharmaceutical companies to the US military has shown interest in the project. Currently, the research team in charge of the project believes that within five years the organ chips will be used in practical research. It goes to show that thinking small often produces the biggest results.
7. What will “organ” chips help to do when they are completed?

My family consists of four people. There’s my father whose name is Jan, my mother whose name is Marie, my brother Peter and of course me. I have quite a large extended family as well but only the four of us live together in our apartment in a block of flats. My father is fifty-two years old, he works as an accountant in an insurance company. He is tall and slim, has got short brown and grey hair and blue eyes. My father likes gardening very much as well as listening to music and reading books about political science. His special hobbies are bird watching and travelling.

Now I’ll describe my mother and my brother. My mother is forty-seven and she works as a nurse in a hospital. She is small and slim, has got short brown hair and green eyes. She likes bird watching and travelling too, so whenever my parents are able to them go to some places interesting for nature watching. Since we have a cottage with a garden they both spend a lot of time there. My brother is sixteen. He is slim and has short brown hair and blue eyes. He also attends high school. He is interested in computers and sports like football and hockey. He also spends a lot of time with his friends.

I have only one grandmother left still living. She is in pretty good health even at the age of seventy- eight so she still lives in her own flat. I enjoy spending time with her when I can. Both my grandfathers died from cancer because they are smokers, which was really a great tragedy because I didn’t get a chance to know them. My other grandmother died just a few years ago. I also have a lot of aunts, uncles, and cousines. The cousine I’m closest to is my uncle’s daughter Pauline. We have a lot in common because we are both eighteen and so we are good friends.

My parents have assigned me certain duties around the house. I don’t mind helping out because everyone in a family should contribute in some way. I help with the washing up, the vacuuming and the shopping. Of course, I also have to help keep my room tidy as well. My brother is responsible for the dusting and the mopping. He also has to clean his own room. Even though my brother and I sometimes fight about who has to do what job, we are still very close. I am also very close to my parents and I can rely on them to help me. My parents work together to keep our home well maintained and it seems they always have some projects or another that they are working on. They respect each other’s opinions and even if they disagree they can always come to a compromise. I hope in the future that I have a family like ours.

Which of the following statements is NOT 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:
Butterflies are among the most extensively studied insects - an estimated 90 percent of the world's species have scientific names. As a consequence, they are perhaps the best group of insects for examining patterns of terrestrial biotic diversity and distribution. Butterflies also have a favorable image with the general public. Hence, they are an excellent group for communicating information on science and conservation issues such as diversity.
Perhaps the aspect of butterfly diversity that has received the most attention over the past century is the striking difference in species richness between tropical and temperate regions.
For example, in 1875 one biologist pointed out the diversity of butterflies in the Amazon when he mentioned that about 700 species were found within an hour's walk, whereas the total number found on the British islands did not exceed 66, and the whole of Europe supported only 321. This early comparison of tropical and temperate butterfly richness has been well confirmed. A general theory of diversity would have to predict not only this difference between temperate and tropical zones, but also patterns within each region, and how these patterns vary among different animal and plant groups. However, for butterflies, variation of species richness within temperate or tropical regions, rather man between them, is poorly understood. Indeed, comparisons of numbers of species among the Amazon basin, tropical Asia, and Africa are still mostly "personal communication" citations, even for vertebrates, In other words, unlike comparison between temperate and tropical areas, these patterns are still in the documentation phase.
In documenting geographical variation in butterfly diversity, some arbitrary, practical decisions are made. Diversity, number of species, and species richness are used synonymously; little is known about the evenness of butterfly distribution. The New World butterflies make up the preponderance of examples because they are the most familiar species. It is hoped that by focusing on them, the errors generated by imperfect and incomplete taxonomy will be minimized.

It's only 36 centimeters tall, but to fans throughout the world, it represents the highest achievement in football. Every four years, teams from all over the globe compete to take home the FIFA World Cup Trophy, yet nobody ever does. Do you know why? Nobody ever takes it home because the 18-carat gold trophy is kept under lock and key by FIFA (Federation Internationale de Football Association). The champions of each World Cup tournament receive only a replica. This is to protect the valuable prize from thieves, who have stolen the World Cup trophy twice in its 75-year history. The little trophy has certainly had a troubled existence. The original trophy was made by a French sculptor, Abel LaFleur, and was called the "Jules Rimet Cup," in honor of the founder of the World Cup tournament. Sometime during the first three World Cup events (1930, '34 and '38), the name changed to simply the "World Cup." Then during World War II, not much was seen or heard of the trophy. It was being kept hidden in a shoe box under the bed of Dr. Ottorino Barassi, the Italian vice-president of FIFA, to prevent it from falling into the hands of the Nazi army. Although the trophy made it safely through the war, it didn't fare so well during the turbulent 1960s. In 1966, the Cup was stolen during a public showing of the trophy prior to the World Cup tournament in England. Luckily, it was found a short time later none the worse for wear in a trash container, by a little dog named Pickles. Four years later, Brazil earned permanent possession of the original trophy by winning its third World Cup title. Unfortunately, the trophy was stolen a second time, in 1983, and was never recovered. The Brazilian Football Association had to have a duplicate trophy made. After the first trophy became the possession of Brazil's football association, a new World Cup Trophy for FIFA was designed by an Italian artist, Silvio Gazazniga, in 1974. This trophy cannot be won outright, but remains in the possession of FIFA, and rest assured they are keeping a close eye on it. Today, World Cup winners are awarded a replica of the trophy that is gold-plated, rather than solid gold like the real one. Gazazniga's World Cup trophy weighs almost five kilograms. Its base contains two layers of a semi-precious stone called malachite, and has room for 17 small plaques bearing the names of the winning teams -enough space to honor all the World Cup champions up to the year 2038. After that, a new trophy will have to be made.
