三、阅读理解
Hello, Dolly!
British scientists have done something that many people thought was impossible: they created the first clone of an adult mammal (哺乳动物). The clone, named Dolly, is a seven-month-old sheep, grown from a cell of an adult female sheep.
What is a clone? A clone is a copy — a genetic copy. Genes are the instructions for life. They tell a cell what to do and how to do it. Genes make each individual plant or animal different and unique. But a clone has the same genes as the original organism (有机体；生物体).
Cloning is not new. Plants have been cloned for centuries. New plants are often grown from cuttings from another plant. Also, plants like pineapples, strawberries and carnations (康乃馨) are sometimes cloned. One benefit of cloning is that we can make many copies of the best and healthiest plants.
It has been much more difficult to clone animals. Frogs have been cloned, but they died as tadpoles, never living long enough to become adult frogs. Mice, sheep and cattle have been cloned from embryos (胚胎). But Dolly is the first healthy clone of an adult mammal. How did they do it?
(1)An unfertilized egg (未受精卵) was taken from a sheep.
(2)The egg nucleus (细胞核) was removed.
(3)A cell was taken from the udder (动物乳房) of a pregnant (怀孕的) sheep. It was “starved”, so that it stopped growing.
(4) The two cells were combined into one and then implanted in a third sheep, where it grew normally.
(5) The clone was born. It was genetically identical to the pregnant sheep in step(3).
This sounds much easier than it actually was. To end up with one clone, the scientists started with 277 udder cells. And they needed in a way to make the egg cell accept a new nucleus. They did that by starving the cell in step (3).
It may soon be possible to clone many types of animals. Will we also be able to clone human organs, or even whole human beings? We have only begun to think about the morality of cloning technology. Maybe the question to ask is not whether we can clone humans, but instead, should we clone humans?
Choose the best answers according to the text.
1. Dolly is a sheep _____ because she is grown from a cell of an adult female sheep.
A. that has not her father B. that has not her mother
C. that has no parents D. that has not any tail
2. Tell which of the following statements is TRUE.
A. Only plants can be cloned.
B. Only strawberries and carnations can sometimes be cloned.
C. Animals and plants have quite a long history of cloning.
D. Genes can tell a cell what to do and how to do it during cloning.
3. From the fourth paragraph we can know that _____.
A. a tadpole is the early stage of a grown-up frog
B. a tadpole is a frog without a tail
C. a tadpole is a pool where frogs can live
D. a tadpole is a clone of an adult mammal
4. What is the right order in the process of the clone of Dolly?
A. Taking an unfertilized egg from an adult female sheep.
B. Removing the egg’s nucleus.
C. Combining the two cells into one and then implanting it in a third sheep.
D. Taking a cell from the udder of a pregnant sheep.
高二英语译林牛津版必修5 Unit 3 Science versus nature 同步练习参考答案
一、1. benefit 2. immoral 3. consequences 4. superhuman
5. for sale 6. using up 7. comment on 8. advances
9. morality 10. on a personal note 11. be put in place
二、1-5 CBDDB 6-10 BCAAA 11-15 ABCAB
三、1-4 CDAC
解析：本文是篇科普时文。全文讲述了克隆羊多莉的出生过程。
1. 根据文章第一段最后一句话知多莉是从一只成年羊的细胞中克隆出来的，所以它根本没父母。
2. D D项句意为“基因在克隆过程中可以告诉细胞做什么及如何去做”，文中第二段正是说的这个意思。第三段指植物可以克隆，第四段指动物也可以克隆，所以A项不正确。从文中第三段可知菠萝也是可以克隆的，所以B项不正确。第三段中指植物已有几个世纪的克隆历史，而没有提到动物的克隆历史，所以C项与题意不符。
3. A 文中第四段第二句中说：人们曾经克隆过青蛙，但它在蝌蚪阶段就死了，并没有活到成年青蛙阶段，所以我们可以判断，蝌蚪是青蛙的早期形态，故A项“蝌蚪是成年青蛙的早期形态”正确。B、C、D项内容与实际不符。
4. C 题干问的是“克隆多莉的正确顺序是什么”，从文中第四段后半部分的内容可知，正确顺序应是C项中所说的。
