Question

【題目】Drugs（藥物）come in different ways. However, can you imagine that drugs come in chicken eggs? A team of scientists from England say that it can come true. They have developed special chickens that lay eggs with drugs inside. These special drugs can help with some kinds of illnesses. Until now, they have made two kinds of drugs. One drug can deal with skin problems and the other can deal with a nerve disease(神經性疾病).

Certain drugs are produced by the special chickens inside their egg whites. These drugs are made of proteins which can be found in animals’ skin, hair, milk and meat. The scientists also use DNA technology to make sure that the drugs are only inside the egg whites. In this way, the chickens can stay healthy.

Besides egg whites, drugs made of proteins come in milk of cows and sheep. Compared with cows and sheep, the special chickens have ascendancy over them. First, they are cheaper to raise. Second, they need less room and grow faster.

These special chickens can pass on their drug-producing ability. So far, five generations of the special chickens have appeared. But scientists may need more time to make the drugs perfect. It’s said that scientists will realize their dream in five to ten years.

【1】What is the passage mainly about?

A. It’s mainly about a serious illness.

B. It’s mainly about a natural ability of chickens.

C. It’s mainly about the special drugs.

D. It’s mainly about the DNA technology.

【2】According to the passage, the special chickens _________.

A. don’t need much room and it grows very slowly

B. were developed by scientists from France

C. produce certain drugs outside the eggs

D. can pass on this drug-producing ability to their children.

【3】The underlined word “ascendancy” in the passage means “________” .

A. problemsB. advantagesC. disadvantagesD. situations

Answer 1

【答案】

【1】C

【2】D

【3】B

【解析】

文章大意：文章主要講述的是一種來源于雞蛋的藥物。英國科學家研制出了一種雞，這種雞產的雞蛋的蛋清中含有一種蛋白藥物，可以用來治病。雖然目前實現(xiàn)了藥物來源于雞蛋，但是科學家還需要很多年來優(yōu)化這種藥物，使其發(fā)揮更好的作用。

【1】推理判斷題。文中首句提到"Drugs come in different forms．However，can you imagine that drugs come in chicken eggs？A team of scientists from England prove that it can come true"藥物來源于各種方式，但是還沒有藥物來源于雞蛋，近來科學家將其成為現(xiàn)實，下文也主要介紹的是藥是如何來源于雞蛋的，可知，故選C。

【2】細節(jié)理解題。根據(jù)These special chickens can pass on their drug-producing ability. 這些特殊的雞可以傳遞它們的產毒能力�？芍�，故選D。

【3】詞義猜測題。文中提到"First，they are cheaper to raise．Second，they need less room and grow faster"第一，養(yǎng)雞比較便宜，第二，養(yǎng)雞不會占用太多空間，這兩點是相對于養(yǎng)牛和羊的優(yōu)點，可知，由此推測詞意為優(yōu)勢，選擇B。
