2009年高考英语阅读理解和任务型阅读课堂综合练习六一阅读理解阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。A Technology is the application(应用) of knowledge to production. Thanks to modern technology, we have been able to increase greatly the efficiency of our work force. New machines and new methods have helped cut down time and expense while increasing overall output. This has meant more production and a higher standard of living. For most of us in America, modern technology is thought of as the reason why we can have cars and television sets. However, technology has also increased the amount of food available to us, by means of modern farming machinery and animal breeding techniques, and has extended our life span via(通过) medical technology. Will mankind continue to live longer and have a higher quality of life? In large measure the answer depends on technology and our ability to use it widely. If we keep making progress as we have over the past fifty years, the answer is definitely yes. The advancement of technology depends upon research and development, and the latest statistics(统计) show that the United States is continuing to pump billions of dollars annually(每年) into such efforts. So while we are running out of some scarce resources(少的资源) we may well find technological substitutes(代用品)for many of them through our research programs. Therefore, in the final analysis the three major factors of production(land, labor and capital) are all influenced by technology. When we need new skills, on techniques in medicine, people will start developing new technology to meet those needs. As equipment proves to be slow or inefficient, new machines will be invented. Technology responds to our needs in helping us maintain our standard of living. 1. What is the best title for the passage? A. The definition of technologyB. Modern technologyC. The application of technologyD. The development of technology2. Which is the main idea of the passage?A. Modern technology is the key to the improvement of standard of living. B. The three major factors of production (land, labor and capital) are all influenced by technology. C. Technology is the response to our needs. D. The United States is making great efforts to advance its technology. 3. According to the passage, people can live a long life with the help of _.A. higher quality of life B. medical technologyC. modern farming machineryD. technological substituteBSpace travel is definitely bad for astronauts bones, reducing their bone density(密度) after only a month of weightlessness, according to French research published on Friday.Laurence Vico and his fellow workers at St Etienne University called for more research into the effects of microgravity, after their study of 15 astronauts from the Russian MIR station showed bone loss continued throughout space flights.“Bone loss was especially striking in four astronauts, ” the scientists reported in the Lancet Medical Journal.They measured the bone mineral density (BMD) of bones in the forearm(前臂) and lower leg of the astronauts who had spent one to six months in space.The BMD loss was significant in the tibia(胫骨) of the lower leg, a weight-bearing bone, but barely changed in the radius(桡骨) of the forearm. “Our results indicate the need to investigate not only different bones, but also different areas of the same bone since not all sites of the skeleton (骨架) are similarly affected by space conditions, ” they added.Without gravity the body isnt bearing any weight so there is no need for calcium (钙) which makes bones strong, and it becomes empty into the bloodstream.The research team suggested in future scientists should try to determine if the loss of bone density was only on weight-bearing bones on longer flights, also the possible recovery after returning to Earth.4. French scientists did their research on Russian astronauts, because _.A. they only cared for the Russian astronautsB. they were not interested in their own astronautsC. the Russian government invited them to do their researchD. the Russian astronauts worked in space for a long time5. Scientists have found that _.A. the BMD loss may cause serious illness to astronautsB. the BMD loss may cause some change in astronauts bodiesC. astronauts shouldnt care about the BMD lossD. astronauts should take some calcium before space travel6. What cause the BMD loss to astronauts, according to this passage?A. The food they eat in space.B. The drinks they take in space.C. The temperature in space.D. The gravity in space.7. In the third paragraph, the word “striking” means _.A. unusualB. simpleC. weakD. slowCSome spiders hunt on the ground, others build webs to trap their food, but the grass water spider catches its prey by running along the surface of the water.This special water spider lives on the grassy banks of streams where mosquitoes, damsel flies and other insects come to feed and b
