It also ordered the makers of the sleeping pills to provide information for patients explaining how to safely use the drugs. Last Wednesday, the FDA announced that some of these drugs can have unexpected and dangerous effects. These include the risk of life-threatening allergic (过敏性的) reactions. They also include rare incidents of strange behavior. These include people cooking food, eating and even driving while asleep. The patients later had no memory of doing these activities while asleep. Last year, a member of the United States Congress said he had a sleep-driving incident. Patrick Kennedy, a representative from Rhode Island, crashed his car into a security barrier near the building where lawmakers meet. The accident happened in the middle of the night and no one was hurt. Mr. Kennedy said he had earlier taken a sleep medicine. He said he was also being treated with a stomach sickness drug that can cause sleepiness. The Food and Drug Administration did not say in its announcement how many cases of sleep driving it has documented. However, the New York Times reported last year about people who said they had strange sleep events after taking the drug Ambien. Some reported sleep-driving and sleepwalking. Others said they found evidence after waking in the morning that they had cooked food or eaten in their sleep. But they had no memory of carrying out the activities. A Food and Drug Administration official says that these serious side effects of sleep disorder drugs appear to be rare. But, he also said there are probably more cases than are reported. He said the agency believes the risk of such behaviors could be reduced if people take the drugs as directed and do not drink alcohol while taking the drugs. The Food and Drug Administration has advised drug companies to carry out studies to investigate the problem.

单选题While NICE's decisions have angered some doctors and patient groups -particularly some oncologists (肿瘤科医生) who say they are unable to prescribe expensive, life- extending cancer drugs- mainstream politicians, the media and most Britons accept NICE's rare rejections as a necessary compromise to keep universal coverage affordable in the face of rising health -care costs. As NICE chairman Sir Michael Rawlins recently told TIME, "All health -care systems have implicitly, if not explicitly, adopted some form of cost control. In the U. S. , you do it by not providing health care to some people. That's a rather brutal way of doing it. " NICE's decisions hear the loudest voice of disapproval fromA. some oncologists.B. mainstream politicians.C. the media.D. most Britons.

单选题 The Smog For over a month, Indonesia was in crisis. Forest fires raged out of control as the country suffered its worst drought for 50 years. Smoke from the fires mixed with sunlight and hot dry air to form a cloud of smog. This pollution quickly spread and within days it was hanging over neighbouring countries including Malaysia, Singapore and Thailand. When the smoke combined with pollution from factories and cars, it soon became poisonous (有毒的). Dangerous amounts of CO became trapped under the smog and pollution levels rose. People wheezed (喘息) and coughed as they left the house and their eyes watered immediately. The smog made it impossible to see across streets and whole cities disappeared as grey soot (烟灰) covered everything. In some areas, water was hosed (用胶管浇) from high-rise city buildings to try to break up the smog. Finally, heavy rains, which came in November, put out the fires and cleared the air. But the environmental costs and health problems will remain. Many people from South-Eastern Asian cities already suffer from breathing huge amounts of car exhaust fumes (汽车排放的废气) and factory pollution. Breathing problems could well increase and many nonsufferers may have difficulties for the first time. Wildlife has suffered too. In lowland forests, elephants, deer, and tigers have been driven out of their homes by smog. But smog is not just an Asian problem. In fact, the word "smog" was first used in London in 1905 to describe the mixture of smoke and thick fog. Fog often hung over the capital. Sometimes the smog was so thick and poisonous that people were killed by breathing problems or in accidents. About 4000 Londoners died within five days as a result of thick smog in 1952.

单选题A new international study shows that six people die every minute from smoking. That equals 3 million deaths around the world every year. If the present rate (率)of smoking continues, the number of deaths each year from smoking could rise to 10 million by the year 2020. The study describes smoking as the biggest cause to deadly diseases among grown-ups in industrial countries. So far most of the smoking deaths have happened on men, especially in developing countries. A researcher at the World Health Organization says 70% of Chinese men smoke more than 15 cigarettes each day. In Latin America about 50% of the men are smokers. There also is a very large number of smokers in the former Soviet Union(苏联)and in the east Europe. And 25% of all smoking deaths worldwide are in those areas of the world. Scientists say smoking will kill 50% of the countries. Smoking is known to cause lung cancer. It also can lead to cancer of the mouth and other parts of bodies. Smokers are more likely than non-smokers to suffer from heart disease. Experts say that people reduce their chance of dying from smoking if they stop smoking completely. They say smokers who give up smoking can improve their health.
