高二英语单项填空简单题查看答案及解析

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

The 1993 movie Jurassic Park wasn’t the first film to show dinosaurs in the modern world. But it did a good job of bringing the idea of cloning dinosaurs into popular culture. It represented dinosaur cloning in a way that made sense to a lot of people, and it was a successful film, making more than $900 million worldwide.

Jurassic Park built on the idea of getting DNA from mosquitoes kept in amber. While this might seem possible at first sight, it’s highly unlikely that scientists could find usable dinosaur DNA in mosquito fossils. Scientists would need a very specific sample-a female mosquito that had taken lots of dinosaur blood immediately before being trapped in amber. Since fossilization in amber is a relatively rare event, the chances of this happening are pretty small.

The lack of possible samples isn’t the only problem. Most insect fossils found in amber are also too young to contain dinosaur blood-dinosaurs were gone by the time the insects became trapped. Many insects went bad from the inside out after they were trapped, leaving nothing inside for scientists to try to find. Finally, the sample would have to be very dry, since DNA can break down quickly in the presence of water.

But if researchers did find a perfectly kept mosquito with a body full of dinosaur blood, bringing back its DNA would still be difficult. The blood with the dinosaur DNA would be surrounded by the body of an insect, which has its own DNA. There could also be DNA from the other cells trapped in the amber. Then, of course, there’s the DNA in the laboratory itself-and in the body of the scientist.

1.Why is the film Jurassic Park mentioned at the beginning?

A.To introduce the topic of cloning dinosaurs.

B.To encourage scientists to clone dinosaurs.

C.To give a simple introduction to dinosaurs.

D.To stress the possibility of cloning dinosaurs.

2.The key to cloning dinosaurs is to gain ________.

A.insect fossils.

B.dinosaur DNA.

C.dinosaur blood.

D.mosquitoes in amber.

3.What is the author’s opinion on cloning dinosaurs?

A.It’s a step away from success.

B.It will be a fruitless attempt.

C.It requires further research.

D.It lacks creative work.

4.What can be a suitable title for the text?

A.Why was Jurassic Park successful?

B.Reasons for dinosaurs’ dying out

C.Can scientists clone dinosaurs?

D.Ways of cloning dinosaurs

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?

As the international demand for narrative(叙事的) film/TV content continues to increase with popular streaming services like Netflix and others the two questions then come: will the coming generations receive most of their entertainment through visual means rather than through the written word and will such an increase of narrative film/ TV reduce the importance of reading?

Growing examples of this trend include the diminishment(减少) of fiction in the common core (核心的)curriculum, the ever－rising culture of computer games, the wave of streaming services of wide international reach, and movies filled with special effects made for children and teenagers. Nor must we ignore the economic dangers that lie ahead for the written word. The narrative film industry is a moneymaker that dwarfs(使相形见绌) the publishing industry.

The other underlying question, of course, is “does it really matter if the written word bows to the world of film/TV?” From my point of view, any diminishment of fiction delivered by words is a loss for mankind.

There is no greater human feature than the imagination. It lies at the very soul of the human species. It is the brain’s most powerful engine. It is the essential muscle of life and like all muscles it must be exercised and strengthened.

Writing and reading are the principal tools that inspire, create and empower our imagination. Anything that diminishes that power is the enemy of mankind.

It should be known that I am not opposed to new media and technological advances. Instead, I have always felt it necessary to adapt to advancing technology. In fact, a number of my novels are in various stages of development for film, TV, and live stage productions. My hope is that the written word will only stand to be complemented(补充)by its visual counterparts(对应物), not pushed to the edge of extinction.

Of course, there are those who will present arguments for the superiority of the moving image over the written word. Each has its place. My argument is for finding the right balance between it and the moving image.

1.In what way does narrative film/TV embarrass the written word?

A.Economic benefits B.International reach

C.Cultural influence D.Educational importance

2.Why does the author value the role of the written word?

A.It strengthens our muscles. B.It helps sharpen imagination.

C.It distinguishes man from each other. D.It paves the way for narrative film/TV.

3.What is the author’s attitude towards technology?

A.Cautious B.Skeptical

C.Positive D.Critical

4.What’s the author concerned about?

A.The fate of reading. B.The extinction of fiction.

C.The impact of the written word. D.The future of the moving image.
