The Human Genome(基因組) Project, a great $3 billion, 15-year task aimed at drawing the genetic map of humans, is now more than 90 percent completed. The scientific and medical communities are very excited about the chances genetic research provides for getting rid of diseases and prolonging(延長)human life. But those communities and policy makers are also 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 fast developing field of biotechnology have provided material for all kinds of work, but the developments of modern science in unlocking the secrets of human genetic code have opened a world of possibilities for human health, as well as for the population imagination.

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

Once these genes are found and studied, researchers can develop new ways to attack infections, 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.

67. Why did the scientists work so hard at mapping the human genome?

A. Because the human genome can destroy many illnesses.

B. Because the human genome’s completion can help to get rid of many diseases.

C. Because they wanted to be better known than others.

D. Because the Human Genome Project can provided a lot of chances of work.

68. According to the passage, which of the following countries is the most advanced in genetic research?

A. Japan           B. Germany         C. The United States          D. China

69. According to the passage, 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 United States began genetic research early in the 19th century.

C. Many medical companies show great interest in drawing the human genome map.

D. The scientists have made great progress in connecting some genes with the cancers.

70. What is mainly talked about in this passage?

A. The great human genome.                     B. The discovery of genes.

C. Unlocking the genetic code.                     D. Genes and scientists.

Although the United States covers so much land and the land produces far more food than the present population needs，its people are by now almost entirely an urban society. Less than a tenth of the people are engaged in agriculture and forestry(林業(yè)), and most of the rest live in or around towns，small and large．Here the traditional picture is changing: every small town may still be very like other small towns，and the typical small town may represent a widely accepted view of the country，but most Americans do not live in small towns any more. Half the population now lives in some thirty metropolitan areas(1arge cities with their suburbs, of more than a million people each—a larger proportion than in Germany or England，let alone France). The statistics(統(tǒng)計)of urban and rural population should be treated with caution because so many people who live in areas classified as rural travel by car to work in a nearby town each day. As the rush to live out of town continues，rural areas within reach of towns are gradually filled with houses, so that it is hard to say at what moment a piece of country becomes a suburb. But more and more the typical American lives in a metropolitan rather than a small town environment．

64. If now America has 250 million people．how many of them are engaged in agriculture and forestry? 

A. About 25 million                    B. More than 25 million 

C. Less than 25 million                 D. Less than 225 million

65. Which of the following four countries has the smallest proportion of people living in metropolitan areas?

A. United States       B. Germany        C. France       D. England

66. What’s the meaning of the word“metropolitan”in the middle of the passage?

A .Of a large city with its suburbs        B. Of small and large towns 

C. Of urban areas                     D. Of rural areas

    Why don’t birds get lost on their long migratory (遷居的) flights? Scientists have puzzled over this question for many years. Now they’re beginning to fill in the blanks.

    Not long ago, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly mainly by night? Tests with artificial stars have proved conclusively that certain night-flying birds are able to follow the stars in their long-distance flights.

    One such bird, a warbler(鳴禽) , had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird’s cage was placed under an artificial star-filled sky at migration time. The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the direction of the make-be-live stars caused a change in the direction of his flight. Scientists think that warblers, when flying in daylight, use the sun for guidance. But the stars are apparently their main means of navigation (導(dǎo)航). What do they do when the stars are hidden by clouds? Apparently, they find their way by such landmarks as mountain ranges, coast lines, and river courses. But when it’s too dark to see these, the warblers circle helplessly, unable to get their direction.

  A. have been known to scientists for many years

  B. are known by everyone

  C. have only recently been discovered

  D. will probably remain a mystery

61. Warblers migrate__________.

  A. from North America to South America

  B. using what is apparently an inborn navigational ability

62. When the stars are hidden by clouds, warblers find their way by__________ .

  A. an artificial star             B. some landmarks

  C. their inborn ability           D. A and B

63. This article is a good example of the way scientists__________ .

  A. discover workable answers to universal questions by studying particular cases(特別案例)

  B. jump to conclusions

  C. find a law and then investigate（調(diào)查）

  D. are disappointed by the habits of animals
