The 1993 movie Jurassic Park wasn’t the first...

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?

It’s not the first movie to show the end of the world. But in the latest box office hit 2012 it is neither aliens nor a killer disease that threaten the human race, but climate change.

Some say the film lacks good dialogue and its science is questionable， others believe German director Roland Emmerich makes up for these flaws in special effects. An earthquake destroys the White House and Yellow stone  National Park ends up in flames．

Emmerich borrows from the old Mayan(玛雅人的) story which says, that the world will end in 2012．He is being criticized for fuelling Internet rumors(传闻) about doomsday(世界末日)

“There is no factual basis for these claims,’’ NASA said on its website. “Credible(可信赖的) scientists worldwide know of no threat connected with 2012,’’ it insisted. “After all, our planet has been getting along just fine for more than 4 billion years, ” they added．

According to the UK’s Daily Telegraph, it was first thought that the disaster would happen in May 2003. When the world continued, supporters picked the last day of the Mayan calendar．

“Every culture has a myth(传说) of destruction(毁灭), just as they have a myth of creation. These myths |of destruction tend to surface(重新出现) during times of crisis(危机), ” Michael A. Ryan, an assistant profess of history，speaking to Purdue University News. Ryan studies apocalyptic(像世界末日的) themes from the Middle Ages at the US university. “Today’s current economic climate is a state of crisis for many people who are worried whether they can afford to feed themselves,”he added.

1.What led to the end of the world according to the film 2012?

A. Aliens．  B. The human race．  C．Climate change． D．A killer disease．

2.What does the underlined word “fuelling’’ in the third paragraph refer to?

A. Making sth. stronger．．    B. Putting gas into a car．

C. Producing power or heat．  D．Burning

3.Which of the following statements about the film 2012 is TRUE according to the text?

A．A big fire destroys Yellow-stone National Park．

B．All scientists in the world know of no threat connected with 2012．

C.  The old Mayan story says that the world will end in

D．Every culture has a myth of destruction rather than creation

4.Why do the rumors about doomsday come about now and then?

A．Because during times of crisis, people tend to worry about their future．

B．Because aliens often threaten the human race．

C．Because killer diseases happen at times．

D.  Because the old Mayan story says that the world will

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

高二英语单项填空简单题查看答案及解析

The famous director of a big and expensive movie planned to film a beautiful sunset over the ocean, so that the audiences could see his hero and heroine in front of it at the end of the film as they said goodbye to each other for ever. He sent his camera crew out one evening to film the sunset for him.

The next morning he said to the men, “Have you provided me with that sunset?”

“No, sir,” the men answered.

The director was angry, “Why not?” he asked.

“Well, sir,” one of the men answered, “we are on the east coast here, and the sun sets in the west. We can get you a sunrise over the sea, if necessary, but not a sunset.”

“But I want a sunset!” the director shouted. “Go to the airport, take the next flight to the west coast, and get one”

But then a young secretary had an idea. “Why don’t you photograph a sunrise?” she suggested, “and then play it backwards? Then it’ll look like a sunset.”

“That’s a good idea!” the director said. Then he turned to the camera crew and said, “Tomorrow morning I want you to get me a beautiful sunrise over the sea.”

The camera crew went out early the next morning and filmed a bright sunrise over the beach in the middle of a beautiful bay. Then at nine o’clock they took it to the director. “Here it is, sir.” They said, and gave it to him. He was very pleased.

They all went into the studio. “All right,” the director explained, “now our hero and heroine are going to say goodbye. Run the film backwards so that we can see the ‘sunset’ behind them.”

The “sunset” began, but after a quarter of minute, the director suddenly put his face in the hands and shouted to the camera crew to stop.

The birds in the film were flying backwards, and the waves on the sea were going away from the beach.

1.One evening, the director sent his camera crew out ______________.
