单选题The Intergovernmental Panel on Climate Change (IPCC) was set up in 1988 to assess information on climate change and its influence. Many hundreds of scientists from many countries participated in its preparation and review. Incorporating new results from the past five years of research on climate change, its third report in 2004 predicted global temperature rises by 2100 of between 1.4℃ and 5.8℃compared to a previous assessment of 1.0 to 3.5℃ for the same period. Although the issue of the changing climate is very complex and some changes are uncertain, temperature rises are expected to affect countries throughout the world and have a severe effect on sea- level rises. Scientists have argued about whether temperature rises are due to human activities or due to natural changes in our environment. Some have believed that the emission of industrial and life wastes turns to warm the surface, while the others have insisted that natural factors, such as changes in solar output or explosive volcanic activity can also be criminal in this case. The IPCC announced in 2001 that "most of the warming observed over the last 50 years is likely to be owing to human activities". This was a more forceful statement than in 1996 when the second report stated that there was a "definite human influence on the climate" which was the first time they had concluded such a link. Many experts believe the faster the climate changes, the greater the risk will be. Key points of the predictions for climate change globally include that by the second half of the 21st century, wintertime rainfall in the northern areas will rise, that at the same time Australia, Central America and southern Africa are likely to see decreases in autumn rainfall, that some land areas in the tropics will see more rainfall, and that there will generally be more hot days over land areas. The IPCC also warned that global surface temperature increases and rising sea level are predicted to continue for hundreds of years after stabilization of greenhouse gas concentrations, owing to the long timescales on which the deep ocean adjusts to climate change. Therefore, further research is required to improve the ability to detect, attribute and understand climate change, to reduce uncertainties and to project future climate changes.

单选题Questions 14-17 are based on the following passage about loneilness．

单选题On the occasion of his 80th birthday, Sir Winston Churchill was presented with his portrait by a well-known modem artist, Graham Sutherland. The painting had been ordered and paid for by the members of Parliament, Though moved by this mark of respect and affection, neither Sir Winston nor Lady Churchill liked it. "It makes me look stupid — which I am not!" protested Churchill in private. Publicly, he only remarked that it was "a fine example of modern art." The Churchills were so unhappy about the portrait that finally they had it destroyed. Churchill died at ninety in 1965. Lady Churchill followed him in 1977. Shortly after her death, the public learned what had happened to Sutherland's painting, and a heated argument broke out. The painter was understandably sad. The artistic community, shocked and angry, claimed that the destruction of the picture had been a crime. Historians said that they regretted the disappearance of a historical document. All agreed that the Churchills didn't have the right to do what they had done. Well — did they? A good part of the public felt that the subject (and owner) of a portrait had the right to get rid of it if it made him so unhappy. The question, however, has been raised many times before: who has the right to a work of art — the sitter, the owner, the donor, or the artist who created it? And when the painting is the portrait of a historical figure, should the right of descendants be considered, as the historians claimed? Another question comes to mind: who is qualified to judge a portrait? Graham Sutherland had told Sir Winston that he would paint him "as he saw him." Churchill never had a chance to see the work in progress since the painter refused to show it to him. He found out only when he received his present that Sutherland had seen him as a heavy, sick, tired old man. None of these questions have been answered yet to everybody's satisfaction.

单选题There was one thing I found rather strange on my first day at Monk''s House. The bathroom was directly above the kitchen and when Mrs. Crane was bathing before breakfast. I could, through the thin floor, hear her whispering to herself, asking questions and giving herself the answers. When Mr. Crane saw that I looked so surprised he told me that Mrs. Crane always said the sentences out loud that she had written at night. She wanted to know if they sounded right and the bath was a good place for trying them out. 　　Every morning, when we carried the breakfast trays to Mrs. Crane''s room I noticed that she had always been working during the night. There were pencils and paper beside her bed so that when she woke up she could work, and sometimes it seemed as if she had got very little sleep. 　　Mrs. Crane''s bedroom was outside the house in the garden; I used to think how inconvenient it must be to have to go out in the rain to go to bed. Her bedroom had been added on to the back of the house; the door faced the garden and a window at the side opened out to a field. I remember that cow came one night and put its head in through the window. It amused Mrs. Crane very much, but in case it happened again Mr. Crane bought the field adding part of it to the garden. Because the writing room was small, he had a larger one built for her at the end of the garden against the church wall. 　　She was tall and thin and very graceful. She had large, deep-set eyes and a wide curving mouth I think perhaps it was this that made her face seem particularly beautiful. Mrs. Crane wore clothes that suited her well. She was not capable of sewing, although sometimes she liked to try. There was one thing in the kitchen that Mrs. Crane carried it out. She returned two or three times a morning, work at it. At last she made it into the shape of a cottage loaf and baked it at just the right temperature

单选题After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day. There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other. Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for Rapid Eye Movement. If you have trouble falling asleep, some people recommend breathing very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep!

单选题Believe it or not, optical illusion (错觉) can cut highway crashes. Japan is a case in point. It has reduced automobile crashes on some roads by nearly 75 percent using a simple optical illusion. Bent stripes, called chevrons (人字形) painted on the roads make drivers think that they are driving faster than they really are, and thus drivers slow down. Now the American Automobile Association Foundation for Traffic Safety in Washington D.C. is planning to repeat Japan's success. Starting next year, the foundation will paint chevrons and other patterns of stripes on selected roads around the country to test how well the patterns reduce highway crashes. Excessive speed plays a major role in as much as one fifth of all fatal traffic accidents, according to the foundation. To help reduce those accidents, the foundation will conduct its tests in areas where speed related hazards are the greatest curves, exit slopes, traffic circles, and bridges. Some studies suggest that straight, horizontal bars painted across roads can initially cut the average speed of drivers in half. However, traffic often returns to full speed within months as drivers become used to seeing the painted bars. Chevrons, scientists say, not only give drivers the impression that they are driving faster than they really are but also make a lane appear to be narrower. The result is a longer lasting reduction in highway speed and the number of traffic accidents.

单选题Centuries ago, man discovered that removing moisture from food helps to preserve it, and that the easiest way to do this is to expose the food to sun and wind. All foods contain water--cabbage and other leaf vegetables contain as much as 93% water, potatoes and other root vegetables 80% , lean meat 75% and fish anything from 80% to 60% depending on how fatty it is. If this water is removed, the activity of the bacteria(细菌) which cause food to go bad is checked. Nowadays most foods are dried mechanically. The conventional method of such dehydration(脱水) is to put food in chambers through which hoi air is blown at temperatures of about 110°C at entry to about 43°C at exit. This is the usual method for drying such things as vegetables, minced meat, and fish. Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them over a heated horizontal steel cylinder or by spraying them into a chamber through which a current of hot air passes. In the first case, the dried material is scraped off the roller as a thin film which is then broken up into small, though still relatively coarse flakes. In the second process it falls to the bottom of the chamber as a fine powder. Dried foods 'take up less room and weigh less than the same food packed in cans or frozen, and they do not need to be stored in special conditions. For these reasons they are invaluable to climbers, explorers and soldiers in battle, who have little storage space. They are also popular with housewives because it takes so little time to cook them.
