June 26, 2000 — the Human Genome(基因组) Project, a great $3 billion, 15-year task aimed at drawing the genetic(遗传的) map of humans, is now more than 90 percent completed. The scientific and medical communities(团体) are very excited about the chances genetic research provides for getting rid of diseases and prolonging(延长) human life. But those communities and policy(政策) makers also are careful about the scientific door they are opening as the project uncovers the mysteries of life. For the last few years, the genetic advances in the developing field of biotechnology(生物技术) have provides material for all kinds of work, but the developments of modern science in unlocking the secrets of the human genetic code(密码) have opened a world of possibilities for human health, as well as for the popular imagination.

While European and Japanese researchers are making rapid progress in decoding(解码) human DNA, the leading organization for genetic research is in the United States, which began in 1990, is “unlocking the code” of the human body to learn how to defeat fatal(致命的)diseases. Already, the Human Genome Project has become widely known and praised for finding the genes(基因) connected with terrible diseases as yet(迄今), and making progress toward separating the genes that show a sign of breast cancer or AIDS.

Once these genes are found and studied, researchers can develop new ways to attack infections(传染), and genetic diseases. Medical companies are very interested in

mapping the human genome, as they expect to develop a lot of new drugs for these illnesses.

1. Why did the scientists work hard at mapping the human genome? A. Because the human genome can destroy many illnesses.

B. Because the human genome's completion can help them get rid of many diseases. C. Because they wanted to be better known than others.

D. Because the human genome can provide a lot of chances of work.

答案解析：答案为B。本题为细节推理题。由第一段第二句话 “the chances genetic research provides for getting rid of diseases and prolonging human life.” 和最后一段首句 “Once these genes are found and studied, researchers can develop new ways to attack infections, and genetic diseases.” 可知，科学家绘制人类基因组图是为了驱除疾病，故答案为B。A选项表述不正确；C、D在文中均未提到。

2. Which country studied the genes most rapidly in the world? A. Japan.

B. Germany.

C. The United States.

D. China.

答案解析：答案为C。本题为细节题。由第三段首句提到的 “…the leading organization for genetic research is in the United States, …”可知，答案为C。.

3. Which of the following is NOT true?

A. If the genes can be found, scientists can study many new ways to cure illnesses. B. The scientists have made great progress in connecting the genes with the cancers. C. Many medical companies show great interest in drawing the human genome map. D. The United States began the Genes Study early in the 19th century.

答案解析：答案为D。本题为细节判断题。由第三段首句提到的 “which began in 1990” 可知，美国是在20 世纪末开始绘制人类基因组图的，故D选项表达错误。

由最后一段首句 “Once these genes are found and studied, researchers can develop new ways to attack infections, and genetic diseases.”可知，A选项与文意符合；由第三段最后一句 “…and making progress toward separating the genes that show a sign of breast cancer or AIDS.” 可知，B选项与文意符合；由最后一段最后一句话 “Medical

companies are very interested in mapping the human genome, …”可知，C选项与文意符合，均不选。

4. The author suggests that the Human Genome Project can cause _______. A. the policy makers to feel very worried and careful B. the scientists to work harder C. many people to find work easily

D. a lot of companies to produce many new drugs

答案解析：答案为B。本题为推理题。由第一段最后一句话 “But those communities and policy makers also are careful about the scientific door they are opening as the project uncovers the mysteries of life.” 可知，A选项表述与文意不符。C选项未提及。由最后一段最后一句话 “Medical companies are very interested in mapping the human genome, as they expect to develop a lot of new drugs for these illnesses.”可知，D选项是文中的一个事实，不需要推理，故不选。

结合全文内容和第一段提到的 “June 26, 2000 — the Human Genome Project, a great $3 billion, 15-year task aimed at drawing the genetic map of humans, is now more than 90 percent completed.” 可以推断，绘制人类基因组图是一个长期的项目，现在虽然完成了百分之九十多，但是作者在文中也暗示了这个项目需要科学家更努力地工作，故B选项正确。

5. The main idea of this article is about _______. A. unlocking genetic code B. the genes' discovery C. the great human genome D. the genes and the scientists

答案解析：答案为A。本题考查文章的主旨大意。结合第二段提到的 “…but the developments of modern science in unlocking the secrets of the human genetic code…”和第三段提到的 “… is ‘unlocking the code’ of the human body to learn how to defeat fatal diseases.” 可知，解读基因密码可以知道如何打败疾病。故答案为A。B、C、D都不是文章的中心。

【2015高考复习】阅读理解

With more and more cars on the road，traffic jams are inevitable.Traffic jams can lead to increased accidents as there are more cars，with more people trying to get to their destination，all the while getting worse.Although it's impossible to avoid traffic jams altogether，there are some tips you can follow to reduce the amount of time on the road.

Check for traffic jams before you leave.You can listen to the radio for traffic news，or check on the Internet to get up-to-minute information on traffic.If the route you want to take is heavy with traffic，you can choose another.

Look for a different route permanently.Most traffic jams occur on busy roads.Using country roads could see you avoiding a lot of traffic.Although the distance you may have to travel is further，it can work out quicker.

Set your car radio to receive traffic bulletins.Many new car stereo systems(汽车音响系统)are equipped with a radio system by which you can hear the traffic channel.This way you can get the latest traffic information and change your journey if necessary. ________.Most traffic jams usually occur during rush hour，so try to avoid this time period if possible.Some jobs offer flexible working hours so that you can travel to work outside of rush hour.Some jobs even allow you to work from home so as to avoid commuting altogether.Ask your manager to see what you can do if traffic is a problem for you.

Use public transport alternatives where available.The easiest way to avoid traffic jams is to take buses or the underground instead of driving your own car.Not only will you avoid traffic jams but you will most likely be saving money as the cost of motoring rises.

【语篇解读】 随着汽车数量的增加，城市的堵车现象日益严重，因此如何减少自己在路上花费的时间就显得非常重要。本文给我们提出了五条可行的建议。

16．The underlined word“inevitable”in Paragraph 1 probably means________. A．hard to accept

B．impossible to avoid D．seen everywhere

C．getting less serious

答案 B [词义猜测题。根据第一段的内容可知，路上的汽车越来越多，交通堵塞是不可避免的。inevitable意为“不可避免的，必然发生的。”] 17．The author wrote the text in order to________. A．explain why there are traffic jams
