Read the following passage and choose the best answer (A, B, C, D):
Exobiology is the study of life that originates from outside of Earth. As yet, of course, no such life forms have been found. Exobiologists, however, have done important work in the theoretical study of where life is most likely to evolve, and what those extrateưestrial life forms might be like. What sorts of planets are most likely to develop life? Most scientists agree that a habitable planet must be terrestrial, or rock-based, with liquid surface water and biogeochemical cycles that somewhat resemble Earth’s. Water is an important solvent involved in many biological processes. Biogeochemical cycles are the continuous movement and transformation of materials in the environment. These cycles include the circulation of elements and nutrients upon which life and the Earth’s climate depend. Since (as far as we know) all life is carbon-based, a stable carbon cycle is especially important. The habitable zone is the region around a star in which planets can develop life. Assuming the need for liquid surface water, it follows that most stars around the size of our sun will be able to sustain habitable zones for billions of years. Stars that are larger than the sun are much hotter and bum out more quickly; life there may not have enough time to evolve. Stars that are smaller than the sun have different problem. First of all, planets in their habitable zones will be so close to the star that they will be “tidally locked” – that is one side of the planet will always face the star in perpetual daylight with the other side in the perpetual night. Another possible obstacle to life on smaller stars is that they tend to vary in their luminosity, or brightness, due to flares and “star spots”. The variation can be large enough to have harmful effects on the ecosystem. Of course, not all stars of the right size will give rise to life; they also must have terrestrial planets with the right kind of orbits. Most solar systems have more than one planet, which influence each other’s orbits with their own gravity. Therefore, in order to have a stable system with no planets flying out into space, the orbits must be a good distance from one another. Interestingly, the amount of space needed is roughly the width of a star’s habitable zone. This means that for life to evolve, the largest possible number of life-supporting planets in any star’s habitable zone is two. Finally, not all planets meeting the above conditions will necessarily develop life. One major threat is large, frequent asteroid and comet impacts, which will wipe out life each time it tries to evolve. The case of Earth teaches that having large gas giants, such as Saturn and Jupiter,.in the outer part of the solar system can help keep a planet safe for life. Due to their strong gravitation, they tend to catch or deflect large objects before they can reach Earth.

Saving the Rainforests
One of the hottest topics related to the environment is rainforests. Despite always being mentioned in the news, many people don’t know very much about these areas or understand why they are so important. The name “rainforest” actually does a pretty good job of describing what they are – tall forests that receive high amounts of precipitation. In a year, rainforests get between 250 to 450 centimetres of precipitation. There are two types of rainforests: tropical rainforests and temperate rainforests. Tropical rainforests are more plentiful and are located in warmer climates, while temperate rainforests are found in places where the weather is a bit milder. In terms of location, rainforests can be found on every continent with the exception of Antarctica. Although they only cover 6 percent of the Earth, over 50 percent of the Earth’s animal and plant species can be found there. Many biologists estimate that there are possibly millions of additional species present there that have yet to be discovered and classified. Over the years, rainforests have gained the nickname “the world’s pharmacy” because more than 25 percent of natural medicines were found there. Many herbs that are used to make medicines can only be found in rainforests. Rainforests are also home to several tribes that have lived off the land for thousands of years. During this time, they have survived by hunting animals and gathering fruits and vegetables. They also possess tremendous knowledge when it comes to crafting and applying medicines made from herbs and plants. Over time, their unique way of life has declined as they have come in contact with modern civilization. Despite their numerous benefits, rainforests have been disappearing at a rapid speed. As the Earth’s population continues to expand, developers have been cutting down their trees to create new lands for farming or urban projects. This could have unfortunate long-term effects on our planet. If deforestation continues at this rate, it is possible that a quarter of all species on the Earth may become extinct in the next 50 years. As it stands, plenty of damage has already occurred. West Africa has had 90 percent of its rainforests destroyed, while the island nation of Madagascar has eliminated 66 percent of its original rainforests as well. As a result, many charities have sprung up with the goal of purchasing and protecting the remaining rainforests. With their help, hopefully we can stop the destruction of one of the planet’s most vital assets.

Movies for the Blind
When you think of the cinema, the phrase ‘watching a movie’ probably comes to mind, and, indeed, moviemakers work very hard to make their films interesting visually. They may use elaborate costumes, beautiful locations, or amazing special effects to tell a story. An actor’s expression or movements can also sometimes say more than words. But what about people who are blind or have trouble seeing? Movies also I contain dialogue, music, and sound effects – things that people don’t need to see in order to enjoy. Movie reviewer Marty Klein, who is blind, created a website called Blindspots to help people choose movies that they can follow without the help of someone explaining what is happening on the screen. He gave a rating, from 1 to 10, based on several things. A movie received a high rating if it has only a few main characters whose voices are easy to recognize. Klein also liked interesting stories without many changes in time and place. A large amount of dialogue between the characters was better than long silences or noisy action scenes. His reviews are still online, but the site is no longer updated. Another blind movie reviewer, Jay Forry, maintains the website Blindsite Reviews. He also writes for newspapers and is a guest on radio shows. Forry gives movies one of five ratings, including, “So good, blind people like it” and “I’m glad I couldn’t see it.” Forry became a writer after going blind at the age of 28, and his writing skills and sense of humour are what keep people reading his reviews or listening to him on the radio. After “watching” the animated movie Up, Forry commented that he wished he, too, could have a talking dog to tell him to watch out for cars and not to “go into the ladies’ restroom again.” Sometimes, though, it’s nice to go to the movie without reading reviews and knowing what to expect. Some movie theaters have begun to offer recorded audio descriptions of the movements, scenery, and special effects so that blind moviegoers can follow what other audience members see on the screen. They usually receive a wireless headset to wear during the movie. This allows them to listen to the narration while still hearing the hearing’s music and other sounds that surround them in the theater. Jay Forry also notes that modern theaters now have excellent sound systems, something he appreciates more than the average moviegoer. In the end, going to the movies should be a fun and exciting experience – for both the sighted and the blind.

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     .

Glenbrook South (GBS) High School is in a suburb of Chicago, lllinois, in the United States. It is an award-winning school with a highly competent teaching staff. It has over 400 Asian Pacific American students-over 17 percent of the students in the school. Of these, the majority are Korean American. This is very unusual in a state where Korean Americans are less than 1 percent of the population. The interactions of the Korean American students at GBS were the subject of an article in Asian Week magazine. Different Korean American students react differently to being in a high school where most students are white. Professor Pyong Gap Min, an expert on Korean life in America, believes that Korean Americans in this situation can sometimes feel inhibited or ashamed of their Korean identity. Asian Week interviewed a number of GBS students, and each had a different attitude. Eighteen-year-old Alice said that she used to spend time only with Korean American friends. Although she felt secure with those friends, she found herself motivated to form closer relationships with non-Koreans, too. She said that she felt she was missing out on new experiences and challenges. Seventeen-year-old John moved in the opposite direction. In junior high school, most of John's friends were white. After coming to GBS, his sense of his Korean American identity was restored, and he decided to have mainly Korean American friends. He feels that he and his Korean American friends understand each other better. For example, they understand about severe parental pressures to succeed at school; John felt his white friends couldn't really understand. Sixteen-year-old Paul has some Korean American friends, but he says he spends most of his time with his white friends. He is often the only Asian American in the group, but he doesn't mind. What Paul likes about the white culture is that he can be more radical - he can be as loud and funny as he wants to be. He says he doesn't see as much of that among the Asian students. Without belittling the importance of what these students had to say, it's important to remember that their opinions at this phase of their lives are bound to change as they grow into adulthood. But these honest opinions can help US better understand issues of cultural relations, and their honesty might help Americans from different cultural groups to get along better in the future.

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
