I’m sure many of you have seen Star Wars, Jurassic Park, Multiplicity, or many of the other movies that describe cloning. Most of what you see in these movies is false. What you don’t know is that cloning could be dangerous, to the clone and to our society as a whole. I think human cloning is wrong mainly for four reasons.

What about identity? Humans are promised the right to their own personalities. What would happen if we ignore those rights by giving them someone else’s genetic identity? True, Cloning may prevent people from possessing their identities.

Also, these is a large power struggle here. Cloning means a degree of power and controls over another person’s physical identity and that ignores their rights and their only personalities. The person doing the cloning would have more power than any parent would have.

Cloning would also deal with killing embryos (胚胎). You might not have known, but Dolly, the sheep that was cloned in 1996, was one of over 200 sheep embryos and hers was the only embryo that survived. The rest died or were thrown away. Imagine if the failure rate was that high when we started to clone humans. cloning means running the risk of wasting too much effort

Cloning someone, at this present time, would be extremely dangerous to the birth mother and the clone. In studies done on cows, 4 out of 12 birth mothers died. There is a very high failure rate, which is shown in the cloning of Dolly. Even if you had a few good embryos, failures have been noticeable in animal tests.

So, should we work ahead in the world of cloning? I say no. the risks are greater than the benefits. It’s dangerous to the clone and to the birth mother. We would be killing human lives in the process. It would also be a violation(侵害) of the clone’s right to its own genetic identity and personality.

1.The author thinks human cloning is wrong mainly for ______ reasons.

2.According to the article, what is the author’s opinion about identity?

3.According to Paragraph 4 ,which is right ?      ____.

4.Why does the author mention some movies in the first paragraph?

5. What is the best title of the passage?

高二英语阅读理解中等难度题查看答案及解析

Have you seen Jurassic Park? In this film, scientists use DNA kept for tens of millions of years to clone dinosaurs. They find trouble, however, when they realize that the cloned creatures are smarter and more dangerous than expected. That’s nothing more than a fiction.

But could we really clone endangered animals?

To date, the most successful attempt to do so was the cloning of a gaur, a rare ox-like animal from southeast Asia. Scientists used a cow to bring the cloned baby gaur, named Noah. Two days after birth, however, Noah died from a common bacterial infection. Other endangered species that may be cloned include the African bongo antelope (羚羊), the Sumatran tiger, the cheetah (猎豹), and the giant panda.

Next, could we really clone extinct animals?

In theory? Yes. To do this, you need a well-kept source of DNA from the extinct animals such as wool mammoth (毛象), Tasmanian tiger, or even dinosaur, and a closely related species, still living, which could serve as a surrogate mother.

In reality? Probably not. On the one hand, it’s not likely that extinct animals’ DNA could survive undamaged for such a long time. Cloning such extinct animals as wool mammoth, Tasmanian tiger, or dinosaur is much more difficult due to the lack of properly well-preserved DNA. On the other hand, for example, a gaur can have a cow as a surrogate mother, definitely not a monkey. But what about an extinct animal as unique as the panda? What species could possibly serve as a surrogate mother?

Cloning presents many exciting possibilities. However, even if extinct animals were brought back, they could not survive in today’s world. Not only do most extinct animals have no habitat to love in, but the other plants and animals they depended on for food may also be gone as well.

1. It can be learned from the text that ________.

A. the gaur is an extinct species

B. the gaur lives in Asia and is endangered

C. scientists have cloned the African bongo antelope

D. both the cheetah and the giant panda live in Asia

2.The underlined words “a surrogate mother” probably refer to a female who ______.

A. gives birth to a baby of its own                 B. cannot give birth to a baby

C. gives birth to a baby for another female             D. provides DNA

3.The difficulty in cloning an extinct species is the lack of ______.

A. both the well-preserved DNA and a surrogate mother

B. both the habitat to live in and the well-preserved DNA

C. both the well-preserved DNA and plants to live on

D. both the habitat to live in and plants to live on

4.In the author’s opinion, it is possible that ______.

A. all the extinct species may be cloned

B. extinct species may be cloned and easily survive

C. a gaur can have a monkey as a surrogate mother

D. some extinct species may be cloned, but not survive
