单选题Problems of the Elderly Gerontologists (老年人问题学者) study how old people are treated within a society and how the elderly deal with the inevitable problems of aging, particularly those involving health and income. Health problems include normal losses in hearing, eyesight, and memory, and the increased possibility of chronic(慢性的)diseases. These losses are gradual and proceed at different rates for each individual. In general, the health of old people today is better than that of earlier generation-a condition that is likely to improve still further as more people receive better medical care throught their lives. Because most old people are no longer in the labor force, a steady source of income is necessary. Systems of pensions and benefits are characteristic of industrial societies. One example is Social Security in the U. S. , which is now increased automatically as the cost of living rises, thus reducing somewhat the effect of inflation. Although the income of retired people is about half that of working people, most manage to remain financially independent. Income needs and health are what people consider most when they decide whether to re-tire or not. Putting an end to the limit on the retirement age is not expected to cause many workers to stay on the job if they can afford to retire. The need to relieve strains on the Social Security System, however, has led to legislation that gradually raises the age at which people can get full benefits. This might force them to work longer in the future. Elderly people themselves often display high spirits, satisfaction with life, and feelings of self-worth. The important factors are health and income. The task of modern societies is to ensure that the aged have their basic needs met and that they can continue to function in the community.

单选题Obtaining Drinking Water from Air Humidity Not a plant to be seen, the desert ground is too dry. But the air contains water, and research scientists have found a (51) of obtaining drinking water from air humidity. The system is based completely on renewable energy and is therefore autonomous. Cracks permeate the dried-out desert ground and the landscape bears testimony to the lack of water. But even here, where there are no lakes, rivers or groundwater, considerable quantities of water are stored in the air. In the Negev desert in Israel, for example; annual average relative air humidity is 64 percent-in every cubic meter of air there aye 11.5 milliliters of water. German research scientists have found a way of converting this air humidity autonomously into drinkable water. "The process we have developed is based exclusively on renewable energy sources (52) thermal solar collectors and photovoltaic ceils, (53) makes this method completely energy-autonomous. It (54) will function in regions where there is no electrical infrastructure." says Siegfried Egner, head of the research team. The principle of the (55) is as follows: hygroscopic brine-saline solution which absorbs moisture runs down a tower-shaped unit and absorbs water from the air. It is then sucked (56) a tank a few meters off the ground in which a vacuum prevails. Energy from solar collector (57) up the brine, which is diluted by the water it has (58) . Because of the vacuum, the boiling point of the liquid is lower than it would be under (59) . atmospheric pressure. This effect is known from the mountains: as the atmospheric pressure there is lower than in the valley, water boils at temperatures distinctly below 100℃. The evaporated, non-saline water is condensed and runs down through a completely filled tube in a controlled manner. The gravity of this water column (60) produces the vacuum and so a vacuum pump is not needed. The reconcentrated brine (61) down the tower surface again to absorb moisture from the air. "The concept is suitable for various water (62) . Single-person units and plants supplying water to entire hotels are conceivable, "says Egner. Prototypes have been built for (63) system components-air moisture absorption and vacuum evaporation-and the research scientists have already (64) their interplay on a laboratory scale. In a further (65) the researchers intend to develop a demonstration facility.

单选题Earth's Inner Core Scientists have long struggled to understand what lies at the planet's center. Direct observation of its center is impossible, so researchers must (1) to other evidence. In 1889, a German scientist detected a severe earthquake in Japan. Geophysicists concluded that shock waves (2) jolts (晃动) from one side of Earth through the center to the other side. Then in 1936, Danish geophysicist Inge Lehmann studied the waves' (3) to determine that within Earth's core of molten (溶化了的) iron lies a solid inner core—but (4) that core was made of eluded (难倒) her. Other geophysicists quickly determined that Lehmann's inner core was composed mostly (5) iron. Since then, Lehmann's discovery has (6) conventional Earth science. But now scientists are challenging traditional theory with new and radical (7) . For example, Earth's center could actually contain an "inner core within the inner core. " claim Ishii and colleague Adam Dziewonski. Analyzing hundreds of thousands of earthquake wave (8) , they maintain that the inner core has at its heart a tiny, even more solid sphere (球体). This sphere "may be the oldest fossil (9) from the formation of Earth," says Dziewonski. Dziewonski and Ishii speculate that shortly (10) Earth formed around 4. 8 billion years ago, a giant asteroid (小行星) smashed into the young planet and nearly melted it. But Earth's center didn't quite melt; it (11) mass as the planet cooled. The core within a core may be the kernel (核心) that endured. "Its presence could change our basic ideas about the (12) of the planet," Dziewonski says. Dziewonski's idea is tame (温和的) compared to the (13) theories of independent geophysicist J. Marvin Herndon. Earth's inner core is made not of iron, he claims, but a (14) of nickel and silicon. Herndon has a truly revolutionary notion. Within the nickel silicide (硅化物) inner core is also an "inner" inner core—an 8km-wide ball of the element uranium. Uranium is radioactive. Herndon thinks the uranium releases heat energy as its atoms (15) fission-split and crash into one another in a chain reaction. In other words, we may live on top of a gigantic, "natural" nuclear power plant.

单选题 下面有3篇短文，每篇短文后有5道题，每题后面有4个选项。请仔细阅读短文并根据短文回答其后面的问题，从4个选项中选择1个最佳答案。{{B}}第一篇{{/B}} {{B}} SQ3R{{/B}} A Proven method for effective textbook reading is the SQ3R method developed by Francis Robinson. The first step is to survey (the S step) the chapter by reading the title, introduction, section headings, summary, and by studying any graphs, tables, illustrations or charts. The purpose of this step is to get an overview of the chapter so that you will know before you read what it will be about. In the second step (the Q step), for each section you ask yourself questions such as “What do I already know about this topic?” and “What do 1 want to know?” In this step you also take the section heading and turn it into a question. This step gives you a purpose for reading the section. The third step (the first of the 3R’s) is to read to find the answer to your questions. Then at the end of each section, before going on to the next section, you recite (the second of the 3R’s) the answers to the questions that you formed in the question step. When you recite you should say the information you want to learn out loud in your own words. The fifth step is done after you have completed step 2, 3, and 4 for each section. You review (the last of the 3R’s) the entire chapter. The review is done much as the survey was in the first step. As you review, hold a mental conversation with yourself as you recite the information you selected as important to learn. The mental conversation could take the form of asking and answering the questions formed from the headings or reading the summary, which lists the main ideas in the chapter, and trying to fill in the details for each main idea.

单选题{{B}}第三篇{{/B}} {{B}} Is the Tie a Necessity?{{/B}} Ties, or neckties, have been a symbol of politeness and elegance in Britain for centuries. But the casual Prime Minister Tony Blair has problems with them. Reports suggest that even the civil servants may stop wearing ties. So, are the famously formal British really going to abandon the neckties? Maybe. Last week, the UK's Cabinet Secretary Andrew Turnbull openly welcomed a tieless era. He hinted that civil servants would soon be free of the costliest 12 inches of fabric that most men ever buy in their lives. In fact, Blair showed this attitude when he had his first guests to a cocktail party. Many of them were celebrities (知名人士) without ties, which would have been unimaginable even in the recent past. For some more conservative British, the tie is a must for proper appearance. Earlier, Labor leader Jim Callaghan said he would have died rather than have his children seen in public without a tie. For people like Callaghan, the tie was a sign of being complete, of showing respect. Men were supposed to wear a tie when going to church, to work in the office, to a party - almost every social occasion. But today, people have begun to accept a casual style even for formal occasions. The origin of the tie is tricky. It started as something called simply a "band". The term could mean anything around a man's neck. It appeared in finer ways in the 1630s. Frenchmen showed a love of this particular fashion statement. Their neckwear (颈饰) impressed Charles Ⅱ, the king of England who was exiled (流放) to France at that time. When he returned to England in 1660, he brought this new fashion item along with him. It wasn't, however, until the late 18th century that fancy young men introduced a more colorful, flowing piece of cloth that eventually became known as the tie. Then, clubs, military institutions and schools began to use colored and patterned ties to indicate the wearer's membership in the late 19th century. After that, the tie became a necessary item of clothing for British gentlemen. But now, even gentlemen are getting tired of ties. Anyway, the day feels a bit easier when you wake up without having to decide which tie suits you and your mood.

单选题Charlie Chaplin Charlie Chaplin was born on April 16, 1889 in London. His father was an entertainer and although not one of the big names, he was doing very well. His mother Hannah was also an entertainer. While they were by no means rich, the music hall provided the Chaplins with a comfortable living. Unfortunately happy life didn't last long. Father's alcoholism was slowly, but surely destroying his marriage. Finally it ended in divorce. But Hannah was indomitable (不屈不挠的). Without her, Charlie Chaplin would have become just one more child lost in the poverty of Victorian London. Somehow she not only managed to keep Charlie and his brother Sydney clean and warm, clothed and fed, but she conjured (变戏法)little treats for them. She would sit at the window watching the passers-by and guess at their characters from the way they looked and behaved, spinning tales to delight Charlie and Syney. Charlie took in her skills and went on using them all his life. Charlie had always believed, even in the worst time, that he had some special potential inside him. He took his courage and went to see one of the top theatrical agents. With no experience at all,he was being offered the part of Billy, the pageboy (小听差) in a new production of "Sherlock Holmes". "Sherlock Holmes" opened on July 27, 1903 at the enormous "Pavilion Theatre". Charlie seemed to change overnight. It was as if he had found the thing he was meant to do. In 1910, when Kamo set off on its yearly American tour, Charlie was regarded as "one of the best pantomime (哑剧)artists ever seen here. " They had reached Philadelphia when a telegram arrived and he was being offered the chance to replace a star in the Keystone film company. Cinema was born in the same year as Charlie, though people still believed it was a passing fad (一时的狂热，时尚), and would never replace live shows. He was kept hanging about for several weeks and he used the time to watch and learn. He was determined to master this new medium. It offered him the chance of money and success and it would set him free from the unpredictability of live audience. Charlie's first film, released in February 1914, was called "Making a living". Though it didn't satisfy Charlie, the public liked it. After that he made ten films and he learned a lot. The public loved him and distributors were demanding more and more Chaplin films. In an incredibly short time, Charlie had become a very important man in motion picture.
