阅读理解 Attitudes to AIDS Now Most people say that the USA is making progress in fighting AIDS, but they don"t know there"s no cure and strongly disagree that "the AIDS epidemic(流行病)is over," a new survey finds. The findings, released Thursday by the Kaiser Family Foundation, reassure activists who have worried that public concern about AIDS might disappear in light of recent news about advances in treatment and declines in deaths. "While people are very optimistic about the advances, they"re still realistic about the fact that there is no cure" says Sophia Chang, director of HIV programs at the foundation. The Kaiser survey, like a recent USA TODAY Gallup Poll, does find that the number of people ranking AIDS as the country"s top health problem has fallen. In the Kaiser Poll, 38% say it"s the top concern, down from 44% in a 1996 poll; in the Gallup Poll, 29% say AIDS in No.1, down from 41% in 1992 and 67% in 1987. Other findings from Kaiser, which polled more than 1,200 adults in September and October and asked additional questions of another 1,000 adults in November: 52% say the country is making progress against AIDS, up from 32% in 1995. 52% say the government spends too little on AIDS. 86% correctly say AIDS drugs can now lengthen lives; an equal number correctly say that the drugs are not cures. 67% incorrectly say that AIDS deaths increased or stayed the same in the past year; 24% know deaths fell. Daniel Zingale, director of AIDS Action Council, says, "I"m encouraged that the American people are getting the message that the AIDS epidemic isn"t over. I hope the decision-makers in Washington are getting the same message… We have seen signs of complacency(自鸣得意). 1. According to the Kaiser Poll, which of the following is NOT correct? A. The country is making progress against AIDS. B. AIDS drugs still cannot save people"s lives. C. AIDS drugs can now make people live longer. D. More and more people die of AIDS now. 2. The word "message" in the last paragraph means . A. printed new B. contact C. meaning D. central idea 3. What do activists worry about? A. Recent news about AIDS is not true. B. People may stop worrying about AIDS. C. Deaths caused by AIDS may not decline. D. Advances in AIDS treatment are too slow. 4. According to the passage, people"s attitude toward the cure of AIDS is . A. optimistic. B. hopeless. C. pessimistic D. realistic. 5. The Gallup Poll shows that the number of people . A. who suffer from the worst disease--- AIDS has fallen. B. who think AIDS threatens the countryside has fallen. C. who worry about AIDS and health problems has fallen. D. who think AIDS is the country"s top health killer has fallen. |

阅读理解 What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today"s leading killers, such as heart disease, cancer, and aging itself, will become distant memories. In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells(细胞) are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond l20 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs. The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on-in much the same way our bodies make new skin cells to take the place of old ones. It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future. 1. The author thinks the question how people die in the future __________. A. is simple B. is funny C. has something to do with bio-technology D. has something to do with environment 2. According to the passage, human death IS now mainly caused by . A. diseases and aging B. accidents and war C. accidents and aging D. heart disease and war 3.In the author" s opinion, today"s most important advance in technology lies in . A. medicine B. the Internet C. brain cells D. human organ 4.Humans may live longer in the future because . A. heart disease will be far away from us B. human brains can decide the final death C. the basic materials of cells will last forever D. human organs can be repaired by new medicine 5.We can learn from the passage that . A. human life will not last more than 120 years in the future B. humans have to take medicine to build new skin cells now C. much needs to be done before humans can have a longer life D. we have already solved the technical problems in building new cells |

阅读理解 Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface(BCI) technology could help people with disabilities send commands to machines. Recently, two researchers, Jose Milan and Michele Tavella from the Federal Polytechnic school in Lausanne, Switzerland, demonstrated(展示)a small robotic wheelchair directed by a person"s thoughts. In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts. "Our brain has billions of nerve ceils. These send signals through the spinal cord(脊髓)to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles," Tavella says. "Our system allows disabled people to communicate with external world and also to control devices." The researchers designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain. Prof. Milan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. "The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair." He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time. 1. BCI is a technology that can ________. A. help to update computer systems B. help the disabled to recover C. link the human brain with computers D. control a person"s thoughts 2. How did Tavella operate the wheelchair in the laboratory? A. By controlling his muscles. B. By talking to the machine. C. By using his mind D. .By moving his hand. 3. Which of the following shows the path of the signals described in Paragraph 5? A. scalp→computer→cap→wheelchair B. computer→cap→scalp→wheelchair C. cap→computer→scalp→wheelchair D. scalp→cap→computer→wheelchair 4. Which of the following would be the best title for the text? A. Switzerland, the BCI Research Center B. New Findings About How the Human Brain Works C. Robotic Vehicles Could Help to Cure Brain Injuries D. BCI Could Mean More Freedom for the Disabled |
