Question

【題目】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. The scientific and medical communities are very excited about the chances genetic research provides for getting rid of diseases and prolonging 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 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.

【1】Why did the scientists work so hard at mapping the human genome?

A. Because the human genome can destroy many illnesses.

B. Because the genetic map’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.

【2】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

【3】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.

【4】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.

Answer 1

【答案】

【1】B

【2】C

【3】B

【4】C

【解析】

試題分析：本文講的是耗資巨大的人類基因組計劃，目的是描繪人類的遺傳圖譜。科學(xué)界和醫(yī)學(xué)界對于遺傳學(xué)研究結(jié)果為擺脫疾病和延長人類壽命帶來的機(jī)會都非常雀躍。一旦發(fā)現(xiàn)并研究了這些基因，研究者就可以針對攻擊免疫系統(tǒng)的疾病和遺傳性疾病研發(fā)新的療法。醫(yī)藥公司對于人類基因圖譜的測定也有很高的興趣，期望針對這些疾病開發(fā)新藥。

【1】B細(xì)節(jié)理解題。根據(jù)第一段第二句The scientific and medical communities are very excited about the chances genetic research provides for getting rid of diseases and prolonging human life. 科學(xué)界和醫(yī)學(xué)界對于遺傳學(xué)研究結(jié)果為擺脫疾病和延長人類壽命帶來的機(jī)會都非常雀躍。從這里可知選B。

【2】C細(xì)節(jié)理解題。根據(jù)第三段中的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. 而美國在遺傳學(xué)研究方面的領(lǐng)先機(jī)構(gòu)自1990年來就致力于解開人體密碼，研究擊敗致命疾病的方法，因此可知選C。

【3】B推理判斷題。根據(jù)第三段中的which began in 1990,可知這個機(jī)構(gòu)在美國創(chuàng)辦于二十世紀(jì)九十年代，而不是十九世紀(jì)，故選B。

【4】C主旨大意題。縱觀全文，再根據(jù)第三段中的“unlocking the code” of the human body to learn how to defeat fatal diseases. 解開人體密碼，研究擊敗致命疾病的方法，因此可知答案為C。
