The Global Environmental Facility, through the United :Nations Development Program, has decided to fund ＄ 9.3 million of the ＄40 million program to help the government of China transform. its market for refrigerators. The refrigerator project began in 1989 when the EPA signed an agreement with the government of China to assist in the elimination of CFCs from refrigerators. Berkeley Lab has been involved in the project since 1995 through the U.S. Environmental Protection Agency, developing the market transformation program based on the success of the first phase of the project, which involved designing and testing CFC (chlorofluorocabon) free, energy-efficient refrigerators. Fridley says that beyond his technical supervisory role, the Laboratory will be involved in training and working with the State Bureau of Technical Supervision as the new efficiency standards are developed. "Market transformation," Fridley explains, "is the process of shifting consumer demand for a product, in this case to a more energy-efficient, environmentally favorable product through voluntary, market based means such as technical assistance and training for manufacturers, consumer education, and financial incentives to manufacture and sell the more efficient products." "Collectively, we developed a technical training program for Chinese refrigerator manufacturers interested in developing CFC free, efficient refrigerators; a financial incentive program to motivate manufacturers to build the most efficient refrigerator possible; and a mass purchasing program for Chinese government agencies that acquire refrigerators in bulk," Fridley says. In 1998, the refrigerator project was awarded an International Climate Protection Award by the EPA. "It is not widely known in the United States, but China has had an energy efficiency policy in place since the early 1980s, says Mark Levine, Environmental Energy Technologies Division director and an advisor to the Chinese government on energy efficiency." The government of China is committed to using energy more efficiently, and this has allowed the economy to grow at nearly twice the rate of energy consumption. "The Energy-Efficient Refrigerator Project will have a significant, direct effect on reducing greenhouse gas and pollutant emissions. We Berkeley Lab are grateful to have the chance to work with the people and government of China on this project, as well as on our other refrigerator production projects in energy data analysis, appliance efficiency standards, and technical advice on cogeneration plants ," adds Levine. The main idea of this passage is ______. A．about refrigerator production in China B．about the energy-efficient refrigerator project in China aided by the UN C．about the American aid to the Chinese government in environmental protection D．about the tremendous increase of China's refrigerator production 此题为多项选择题。

The radiation comes as a result of the 500 atomic bomb tests carried out in the atmosphere by the nuclear nations in the 1950s and 1960s. Long-lived isotopes in the fall-out have built up in Arctic lichens which are the reindeer's staple diet. The reindeer have been found to concentrate the isotopes in their bodies. Animals are affected all over the Arctic, with the most radioactive reindeer in Canada, Alaska and Siberia's Taimyr Peninsula. Enormous amounts of reindeer meat — some 14,000 tonnes — are eaten in the Arctic each year. Research at the Danish Riso National Laboratory has found that reindeer herders, who consume a lot of the meat, take in 300 times more radiation each year than is the average anywhere in northern Europe. Norway's Radiation Protection Authority estimates that many hundreds of herders have died of cancer as a result. Meanwhile reindeer are emerging as one of the greatest environmental threats to the Norwegian Arctic. Over-grazing and trampling is causing more damage to the fragile tundra than pollutants from the world's worst-offending factories. Over the last 40 years the number of reindeer in the Norwegian Arctic have doubled, reaching 20 animals per square kilometre, a very high density. Research by the Norwegian and Danish geological surveys and Russia's Kola Science Centre have found that 75 percent of the moss in the Norwegian Arctic and 85 percent of lichen have been "severely damaged" by reindeer. Three-quarters of the area is suffering from soil erosion. By contrast, two of the world's most polluting factories---nickel smelters in Russia's Kola peninsula — have about 10 percent of the moss and 14 percent of the lichen in the area. Even the Saami people, who own most of the reindeer, admit that the animals may be causing problems. Lars-Ander Baer, vice-president of their council, admitted to a conference on the Arctic environment recently: "We simply don't know how many reindeer the northern part of Norway can take." Which of the following is NOT a cause of the problem under discussion？ A．Over-grazing. B．Radioactive contamination. C．Poaching. D．Trampling.

We don't know what the effects would be on healthy human cells, Marinelli told New Scientist magazine. In the Italian study, after 24 hours 20 percent more leukemia cells died than healthy cells but longer exposure to the radio waves triggered genes in the surviving cancer cells to divide aggressively. The results of the study do not show any direct threat to human health but they support the belief of some scientists who say radiation can damage DNA and destroy the cell repair system, thus making tumors more deadly. But animal studies, including recent research by Australian scientists at the Institute of Medical and Veterinary Science in Adelaide, have shown that radiation from mobile phones does not trigger the growth of tumors. The WHO (i.e., The World Health Organization) has called for more research into the potential health hazards of mobile phones and has urged people to limit their use of them. A British government inquiry, which concluded that there was no evidence that mobile phones are a danger to health, has advised parents to discourage their children, whose brains are still developing, from using them excessively. What is the speaker's main topic？ A．Effects of using mobile phones on healthy human cells. B．Risks of developing cancer involved in the use of mobile phones. C．Damage to healthy cells caused by the use of mobile phones. D．The potential health hazards of mobile phones on humans.

You can make your planning more effective by appreciating the direction in which professional careers are shifting within that larger picture.【66】But more than half the students who receive PhDs in science and engineering obtain work outside academe—a proportion that has increased steadily for 2 decades. And full-time academic positions in general are more difficult to find than they were during the 1960s and 1970s, when the research enterprise was expanding more rapidly. 【67】The end of the Cold War has removed some incentive for the federal government to fund defense-oriented basic research. Increased national and global competition has forced many industries to reduce expenses and staff. That means that there are fewer research and development positions in universities, industries, and government laboratories than there are qualified scientists and engineers looking for them. 【68】For example, there are strong public pressures for universities to shift their emphasis toward teaching and toward undergraduate education; the number of positions for permanent faculty has decreased; professors are no longer required to retire at a particular age; and more part-time and temporary faculty are being employed.【69】In engineering, careers are being transformed by several intersecting trends.【70】Companies value multilingual workers with a breadth of competencies—managerial as well as technical—and the ability to access and apply new scientific and technologic knowledge. The more flexible and mobile you can be, the more opportunities you will have and the greater will be your control over the shape of your career. A. Powerful changes have swept through the universities. B. All those trends 'affect the universities' ability to hire scientists and engineers. C. For example, increasing numbers of physicists, mathematicians, and engineers find their skills valued in the financial arena. D. International companies now draw employees from many nations, seeking out valued experts from a global pool of labor to work project by project. E. For example, for many students, a PhD will mean a career as an academic researcher. F. As our society changes, so too do the opportunities for careers in science and engineering. (66)

A．become more stable B．report increased earnings C．do less well in the stock market D．perform. worse in lawsuits

Researchers had a group of non-diabetic men and a group of men with type II diabetes, all more than 60 years of age, exercise on bicycles six times a week for three months. After the three months the doctors measured how much sugar the test subjects’ muscles could make use of as a measure for how well their insulin worked. Associate Professor Dr Flemming Dela of the Muscle Research Center said the tests demonstrated that the exercising diabetics had made as good use of insulin as the healthy non-diabetic persons. “This means that the insulin works just as well for both group. Physical exercise cannot cure people of diabetes, but it can eliminate almost all their symptoms. At the same time it can put off the point at which they have to begin taking insulin,” Dela said. Insulin is a hormone produced by the pancreas(胰腺) , controlling sugar in the body and is used against diabetes. Dela said that to achieve the desired effect diabetics need only exercise to the point where they begin to sweat, but that the activity has to be maintained since it wears off after five days without sufficient exercise. Most diabetics realize that they have to watch their diet while remaining unaware of the importance of exercise, Dela added. 第6题：What is the effect of exercise on elderly people with type II diabetes？ A．It can worsen their symptoms. B．It can help the body make better use of insulin. C．It can help them to eat more. D．It can cure them of the disease.

"It says that the chimpanzee group that gave rise to HIV… this chimp community resides in Cameroon," said Beatrice Hahn of the University of Alabama, who led the study. "But that doesn’t mean the epidemic originated there because it didn’t," Hahn, who has been studying the genetic origin of HIV for years, said in a telephone interview. "We actually know where the epidemic took off. The epidemic took off in Kinshasa, in Brazzaville." Kinshasa is in the Democratic Republic Congo, formerly Zaire, and faces Brazzaville, in Congo, across the Congo River. Studies have traced HIV to a man who gave a blood sample in 1959 in Kinshasa, then called Leopoldville. Later analysis found the AIDS viros. In people, HIV leads to AIDS but chimps have a version called simian immune deficiency virus (SIV) that causes them no harm. Humans are the only animals naturally susceptible to HIV. AIDS was only identified 25 years ago. The virus now infects 40 million people around the world and has killed 25 million. Spread in blood, sexual contact and from mother to child during birth or breastfeeding, HIV has no cure and there is no vaccine, although drug cocktails can control it. And like so many new infections, AIDS appears to have been passed to humans from animals they slaughtered. SIV has been found in captive chimps but Hahn wanted to show it could be found in the wild too. Her international team got the cooperation of the government in Cameroon and they hired skilled trackers. "The chimps in that area are hunted. It’s certainly impossible to see them. It is hard to track them and find these materials," she said. But the trackers managed to collect 599 samples of droppings. Hahn’s lab found DNA, identified each individual chimp and then found evidence of the virus. "We went to 10 field sites and we found evidence of infection in five. We were able to identify a total of 16 infected chimps and, we were able to get viral sequences from all of them," Hahn said. Up to 35 percent of the apes in some communities were infected. Not only that, they could find different varieties, called clades, of the virus. "We found some of the clades were really, really very closely related to the human virus and others were not," she said. Chimps separated by a fiver were infected with different clades, Hahn said. And a river may have carded the virus into the human population. "So how do you get from southern Cameroon to the Democratic Republic of Congo？" Hahn asked. "Some human must have done so. There is a river that goes from that southeastern comer of Cameroon down to the Congo River." Ivory and hardwood traders used the Sangha River in the 1930s, when the original to-human transmission is believed to have happened. Haha’s study suggests the virus passed from chimpanzees to people more than once. "We don’t really know how these transmissions occurred," Hahn said. "We know that you don’t get it potting a chimp, or from a toilet seat, just like you can’t get HIV from a toilet seat. It requires exposure to infected blood and infected body fluids. So if you get bitten by an angry chimp while you are hunting it, which could do it." Hahn’s study only applies the H1V group M, which is the main strain of the virus responsible for the AIDS pandemic. "It’s quite possible that still other (chimpanzee SIV) lineages exist that could pose risks for human infection and prove problematic for HIV diagnostic and vaccines," her team wrote. According to Hahn, the H A．Cameroon. B．Kinshasa and Brazzaville. C．Congo River. D．Nile River.
