单选题Sino-Japan Animosity (敌意) Lessens Chinese and Japanese people view each other slightly more positively than last year, according to a survey released on Wednesday at a press conference in Beijing. The survey is jointly sponsored by China Daily and Genron NPO (非营利性的组织), a Japanese think tank similar to the American Council on Foreign Relations. It also found overwhelming; agreement in both countries that Sino-Japanese relations were important. The survey is a pan of the Beijing-Tokyo Forum, an annual gathering of senior government officials and representatives from Chinese and Japanese NGOs (非政府组织) designed to improve communication and understanding between the two countries. Conducted every year for five years now, the survey focused on two different groups of people: ordinary citizens, and intellectuals. In China, the intellectual group was comprised mainly of university students from well-known schools like Peking University. In Japan, the "intellectual" group was mainly made up of previous members of Genron NPO. Among ordinary Chinese polled, 35.7 percent said they have "very good" or "relatively good" impressions of Japan, a 5.5-percentage-point increase compared with last year. 45.2 percent of Chinese students had a positive impression of Japan, two percentage points more than last year. Only 26.6 percent of Japanese have a positive impression of China, however. Still, an overwhelming majority of the respondents from each country said Sino-Japanese relations were "important" and wanted their leaders to deepen talks and cooperation with each other. But 51.9 percent of ordinary people and 42.4 percent of students in China said they saw no change in relations between the two countries over the last year. In Japan, 64.8 percent of those ordinary people and 53.4 percent of intellectuals surveyed shared the view that there was no improvement in bilateral ties this year. Historical issues and territorial disputes remain two major obstacles to improving bilateral relations, the survey found. What concerns the Chinese most are historical issues, visits by Japanese officials to Yasukuni Shrine (靖国神社), and the Nanjing Massacre (大屠杀). Perceptions on economic and trade relations have improved, though. About 47 percent of ordinary Japanese said China had been "helpful" this year in fighting the global economic crisis, compared with just 30 percent last year. The percent of Japanese intellectuals who said Chinese economic growth was good for Japan increased from 65.8 percent to 81.4 percent this year. Cooperation in East Asian issues, trade and investment, energy, and the environment and climate change top the list of common concerns that people in China and Japan want their leaders to talk about in bilateral (双边的) meetings, the survey found. Civil exchanges were regarded by the most people from the both countries as an important way to improve relations. 90.7 percent of the students and 85.7 percent of the ordinary people in China and 95.8% of intellectuals and 74.8% of the ordinary people in Japan viewed civil exchanges as "important" or "relatively important". Chinese and Japanese both learn about each other's countries mostly through television news and newspapers, the survey found.

单选题 阅读下面这篇短文，短文后列出7个句子，请根据短文的内容对每个句子做出判断。如果该句提供的是正确信息，请选择A；如果该句提供的是错误信息，请选择B；如果该句的信息文章中没有提及，请选择C。 Suppose you make your parents so happy, they decide to have another baby just like you. It might be flattering(讨人喜欢的), but how would you feel about having a little brother or sister who is also your twin? A laboratory experiment conducted last fall suggests it may someday be possible. For the first time ever, scientists made exact copies, or clones(克隆), of a human embryo. Although the embryos grew for only six days, cloned embryos could theoretically be implanted in a woman's womb(子宫)and develop into normal babies. Or they could be frozen and implanted years later. The scientists developed their cloning technique to make it easier for childless couples to have babies by in vitro(在体外的)fertilization. In this procedure, sperm(精子) from the man fertilizes an egg from the woman in a laboratory dish. In most case, doctors must try implanting several embryos before one stays in the womb. Cloned embryos would give them many more embryos to implant. But the technique could also be used for other purposes. Parents might freeze embryos cloned from their children so that they could be replaced if any of them died. The clones would also be ideal donors if the children needed organ transplants. Another possibility: Childless couples could go to a bank of frozen embryos and choose a child just like one who's already living. Some people are concerned that these couples might pick only beautiful, successful children. The ethical dilemmas(困境)of cloning have not yet been discussed fully because the public assumed it was a long way off. Many people are calling for(要求，提倡)controls on cloning immediately before the practice is abused. What do you think?

单选题Fruit and Vegetable Juices as Beneficial to Health as Fruits and Veggies A. European study has revealed that 100 percent fruit and vegetable juices are as effective as their whole fruit/vegetable counterparts in reducing risk factors related to certain diseases. The conclusion is the result of the study designed to question traditional thinking that 100 percent juices play a less significant role in reducing risk for both cancer and cardiovascular disease than whole fruits and vegetables. Juices are comparable in their ability to reduce risk compared to their whole fruit/vegetable counterparts, according to several researchers in the United Kingdom who conducted the literature review. The researchers analyzed a variety of studies that looked at risk reduction attributed to the effects of both fiber and antioxidants. As a result, they determined that the positive impact fruits and vegetables offer come not from just the fiber but also from antioxidants which are present in both juice and the whole fruits and vegetables. "When considering cancer and coronary heart disease prevention, there is no evidence that pure fruit and vegetable juices are less beneficial than whole fruit and vegetables," the researchers said. The researchers added that the positioning of juices as being nutritionally inferior to whole fruits and vegetables in relationship to chronic disease development is "unjustified" and that policies, which suggest otherwise about fruit and vegetable juices, should be re-examined. The researchers who authored the paper suggest that more studies in certain area are needed to bolster their findings. "Although this independent review of the literature is not designed to focus on any particular 100 percent juice, it does go a long way in demonstrating that fruit and vegetable juices do play an important role in reducing the risk of various diseases, especially cancer and cardiovascular disease, " said Sue Taylor. Her opinion is in agreement with the Juice Products Association, a non-profit organization not associated with this research. She added that appropriate amounts of juices should be included in the diet of both children and adults, following guidelines established by leading health authorities. Taylor also points to a large epidemiological study, published in the September 2006 issue of the Journal of Medicine, which found that consumption of a variety of 100 percent fruit and vegetable juices was associated with a reduced risk for Alzheimer's disease. In fact, that study found that individuals who drank three or more servings of fruit and vegetable juices per week had a 76 percent lower risk of developing Alzheimer's disease than those who drank juice less than once per week. The study was published in the International Journal of Food Science and Nutrition (2006).

单选题{{B}}第三篇{{/B}} {{B}} Sunbath and Skin Cancer{{/B}} In the summer, millions of Americans will offer up their bodies to the sun rays. A tan indicates health and beauty, and most sun worshippers will sacrifice a lot to achieve it, including themselves. With each hour, the sun's ultraviolet (紫外线的) radiation produces irreversible (不可逆的) damage, hastening the development of unsightly wrinkles. And with each year on the beach or rooftop, the sunbather increases his risk of getting skin cancer. Skin cancer is by far the most common form of cancer. An estimated 400,000 new cases will be detected this year in the United States, and almost all of them can be blamed on over-exposure to the sun. Fortunately ,most of these cancers are highly curable. But they can be disfiguring and take time to treat. For that reason, sun worshippers should treat deity with a good deal of awe(敬畏). Sunburn, of course, is the initial hazard posed by UV radiation. Prolonged exposure to UV, however, interferes with the production of collagen fibers in the dermis (真皮层), causing the skin to lose elasticity (弹性) and creating premature wrinkles. Further deterioration (恶化) of the dermis deprives the epidermis (表皮层)of nutrition and causes it to become thin and dry. Cancer is UV's final result. Shortwave radiant energy, especially from the UV-B band, breaks the strands of DNA. Enzymes (酶) work constantly to rearrange the (变异的) DNA into proper sequence, but with repeated UV exposure, the repair process may eventually break down. Then the mutant DNA may produce a colony of cancer cells. But skin cancer may be avoided with a good dose of common sense. People with fair skin and blue eyes who burn easily stand the highest risk. Special danger spots are the parts of the body most constantly exposed to the sun, such as the cheeks, nose, lower lip and the ears. People who have already developed precancerous (癌变前的) lesions (伤害) or had one skin-cancer growth stand a greatly increased chance of developing others. Dermatologists (皮肤科医生) recommend avoiding the sun when it is most intense between 11 a.m. and 3 p. m. Anyone who insists on sunbathing should use a good sun screen. These lotions and salves contain chemicals that block out the burning UV-B radiation while permitting the tanning rays to reach the skin.

单选题 阅读下面这篇短文，短文后列出7个句子，请根据短文的内容对每个句子做出判断。 {{B}} The Ice Age{{/B}} Twenty thousand years ago, the earth was held in control by relentlessly (不宽容地) probing fingers of ice that drew power from frigid strongholds in the north and crept southwestward to bury forests, fields, and mountains. Landscapes that were violated by the slowly moving glaciers(冰川)would carry the scars of this advance far into the future. Temperatures dropped deeply, and land surfaces in many parts of the world were depressed by the unrelenting weight of the thrusting ice. At the same time, so much was drawn from the oceans to form these huge glaciers that sea levels around the world fell by three hundred and fifty feet, and large areas of the continental shelf became dry land. This period of the Earth's history had come to be called the Ice Age. In all, about eleven million square miles of land were covered with ice. The Ice Age terminated about fourteen thousand years ago when the ice sheets began to retreat. It took about seven thousand years for the ice to retreat to its present level.

单选题Heat and Health Extremely hot weather is common in many parts of the world. Although hot weather just makes most people hot, it can cause medical problems--and death. Health experts say that since the year 1900, extremely hot weather has killed more people in the United States than any other natural event. One year--the unusually hot summer of 1980--heat caused about 1,700 deaths in the United States. In 1995, more than 600 people died in a similar heat wave in one city--Chicago. To measure extreme heat, government weather experts have developed the Mean Heat Index. It measures the average of how hot it is felt all day on an extremely hot day. Experts say it is the total heat of a hot day or several hot days that can affect health. Several hot days are considered a heat wave. Experts say heat waves often become deadly when the nighttime temperature does not drop much from the highest daytime temperature. The most common medical problem caused by hot weather is heat stress. Usually, it also is the least severe. For most people, the only result of heat stress is muscle pain. The pain is a" warning that the body is becoming too hot. Doctors say drinking water will help the pain disappear after the body again has the right amounts of water and salt. For some people, however, the result is much more serious. For example, doctors say some people face a greatly increased danger from heat stress. These people have a weak or damaged heart, high blood pressure, or other problems of the blood system. Severe heat can help cause a heart attack or stroke. Health experts say this is the most common cause of death linked to hot weather.
