Passage 1
Questions 1 to 5 are based on the following passage:
Spending 50 minutes with a cell phone close to your ear is enough to change brain cell activity in the part of the brain closest to the antenna (天线). But whether that causes any harm is not clear, scientists at the National Institute of Health said at a conference last month, adding that the study will not likely settle concerns of a link between cell phones and brain cancer. "What we showed is glucose (葡萄糖) metabolism (代谢) (a sign of brain activity) increases in the brain in people who were exposed to a cell phone in the area closest to the antenna," said Dr. Nora Volkow of the NIH, whose study was published in the Journal of the American Medical Association. (76) The study was meant to examine how the brain reacts to electromagnetic fields caused by wireless phone signals.
Volkow said she was surprised that the weak electromagnetic radiation (电磁辐射) from cell phones could affect brain activity, but she said the findings do not shed any light on whether cell phones cause Cancer. "This study does not in any way indicate that.What the study does is to show the human brain is sensitive to electromagnetic radiation from cell phone exposures." Use of the devices has increased dramatically since they were introduced in the early 1980s, with about 5 billion cell phones now in use worldwide.
Some studies have linked cell phone exposure to an increased risk of brain cancers, but a large study by the World Health Organization did not offer a clear answer to this. Volkow's team studied 47 people who had their brain examined while a cell phone was turned on for 50 minutes and another while the phone was turned off. While there was no complete change in brain metabolism, they found a 7 percent increase in brain metabolism in the region closest to the cell phone antenna when the phone was on.
(77) Experts said the results were interesting, but urged that they be understood with great care. “Although the biological significance, if any, of increased glucose metabolism from too much cell phone exposure is unknown, the results require further investigation,” Henry Lai of the Unive

Passage 2
Questions 6 to 10 are based on the following passage:
Human beings have always had an ability to attend to several things at once. (78) Nor is electronic multitasking entirely new: We've been driving while listening to car radios since they became popular in the 1930s. But there is no doubt that multitasking has reached a kind of warp speed in the era of Web-enabled computers, when it has become routine to conduct several IM (即时通讯) conversations, watch TV and use the computer all at once.
But what's the impact of this. media consumption? And how are these multitasking devices changing how kids learn, reason and communicate with one another? Social scientists and educators are just beginning to deal with these questions, but the researchers already have some strong opinions.
(79) Although multitasking kids may be better prepared in some ways for today's fast-paced workplace, many scientists are positively alarmed by the trend. Kids that are instant messaging while doing homework, playing games online and watching TV, aren't going to do well in the long run.
On the positive side, multitasking students tend to be extraordinarily good at finding and using information. And probably because modem childhood centers around visual (视觉的) rather than print media, they are especially skilled at analyzing visual data and images.
Many educators and psychologists say parents need to actively ensure that their teenagers break free of uncontrollable engagement with screens and spend time in the physical company of human beings--a growing challenge not just because technology offers’ such a handy option but because so many kids lead highly scheduled lives that leave little time for old-fashioned socializing and family meals. Indeed, many teenagers and college students say overcommitted (任务过重的) schedules drive much of their multitasking.

Passage 3
Questions 11 to 15 are based on the following passage:
The nuclear power emergency at a Japanese atomic power plant last March could lead to a major re-examination in European countries that are already building such plants or are considering a shift from fossil (化石) fuels to nuclear energy to fight climate change. With the terrible accident 25 years ago in Chemobyl (切尔偌贝利) beginning to fade in European memories, governments across Europe have grown more open to using more nuclear power. Enthusiasm for nuclear power is particularly strong in Eastern Europe, which wants to move away from dependence on Russian oil and natural gas, and on heavily polluting coal-fired power plants. Eastern governments have begun improving existing nuclear plants or are building or planning new ones. But as Japan struggled to deal with her nuclear crisis, discussion about the good and the bad of nuclear power became heated.
(80) In Germany, nuclear power has been a repeatedly argued and widely felt issue for decades. Up to 70 percent of Germans oppose nuclear power. Recently, about 40,000 people turned out to form a human chain near a nuclear plant to protest government policies on nuclear power. "The accident in Japan could lead to a major rethink in Europe," said Henrik Paulitz of the International Doctors for the Prevention of Nuclear War. "Governments have not been quite open about the safety levels of the nuclear power plants."
Chancellor (总理) Angela Merkel heads a center-right unity government that supports the use of nuclear power. Her government recently made a disputed decision to extend the life of the country's 17 nuclear power plants by an average of 12 years. She will now face more pressure to change that policy. She called an emergency meeting with her senior ministers, “We know how safe our plants are and that we do not face a threat from such a serious earthquake or violent tidal wave," Mrs. Merkel said after the meeting. "We will learn what we can from the events in Japan.”
