Many of us remember being in awe(敬畏) when we saw cloned dinosaurs running wild in the film Jurassic Park. And the idea of using technology to revive(恢复) extinct species has long fascinated not only writers and directors, but scientists as well.

According to The Telegraph, woolly mammoths(长毛猛犸象), which featured in the popular Ice Age animated movie series, “may walk the earth once more” now that scientists have taken another step toward realizing a long-held dream—recreating their DNA.

Mammoths became extinct around 10,000 years ago. However, since the discovery of near-perfect preserved remains in Arctic permafrost(北极冻土带) in May 2013, a variety of research studies have been carried out since.

Geneticists from Harvard University analyzed DNA from the remains, looking for genes which separated mammoths from elephants, such as hairiness and ear size. They then used the results to reproduce exact copies of 14 mammoth genes. “It is the first time that mammoth genes have been alive—although so far it has only been done in the lab,” George Church, lead researcher of the project, told the Sunday Times.

Church then used a new technique which allows scientists to edit DNA carefully, replacing sections of elephant DNA with the mammoth genes. So “we now have functioning elephant cells with mammoth DNA in them,” he said.

However, Church ruled out the possibility of bringing the mammoths back to life via cloning from frozen remains. He said he “preferred to focus on rebuilding the full mammoth genome(基因组) by analyzing DNA from preserved remains and putting it into the cells of its closest living relative – the Asian elephant,” reported The Telegraph.

Church argued that the return of the woolly mammoth—or rather, the return of something very similar—could help bring back fragile(脆弱的) ecosystems. However, some scientists believe that bringing back the mammoth would be unethical.

Professor Alex Greenwood, an expert on ancient DNA, said: “We may face the extinction of African and Asian elephants. Why bring back another elephant from extinction when we cannot even keep the ones that are not extinct around?” he told the Sunday Times. “What is the message? We can be as irresponsible with the environment as we want. Then we’ll just clone things back?”

“Money would be better spent focusing on conserving what we do have than spending it on an animal that has been extinct for thousands of years,” he said.

1.We can learn from the article that ______.

A. cloned mammoths followed cloned dinosaurs to get revived

B. the technology to revive mammoth genes is already mature

C. George Church and his colleagues tried to reproduce mammoth DNA

D. Church and his team managed to list all the genes that separate mammoths from elephants

2.According to Church, what is the significance of his study?

A. It could help prevent the extinction of the Asian elephant.

B. It could help people better tell elephant DNA from mammoth genes.

C. It could help bring back some extinct species and save fragile ecosystems.

D. It could help bring mammoths back to life via cloning from frozen remains.

3.The underlined word “unethical” in Paragraph 7 is closest in meaning to ______.

A. unacceptable B. misled

C. impractical D. illegal

4.According to the article, Professor Alex Greenwood believes that _______.

A. there is no need to worry about the extinction of African and Asian elephants at present

B. it’s necessary to bring back species that are beneficial to human beings from extinction

C. the return of the woolly mammoth would help to balance ecosystems

D. it’s more important to protect present species than to bring back extinct ones

Sometimes life trips you up，but knowing how to approach failure can be the first step to success. When author J. K. Bowling addressed the graduating class at Harvard last June，she didn't focus on success. Instead，she spoke about failure. She related a story about a young woman who gave up her dream of writing novels to study something more practical. However，she ended up as an unemployed single mom. But during this hard time，she realized she still had a wonderful daughter，an old typewriter，and an idea that would become the foundation for rebuilding her life.“Perhaps you've heard of Harry Pottery You might never fail on the scale I did，” Bowling told the audience.“But it is impossible to live without failing at something，unless you live so cautiously that you might as well not have lived at all. You will never truly know yourself , or the strength of your relationships，until both have been tested by hardships. Such knowledge is a true gift， for it is painfully won，and it has been worth more to me than any qualification I ever earned.”

Lots of Americans are tasting failure for the first time now and immediately trying to spit it out. Whether it's unemployment, or the evaporation(消失)of hard-earned savings, the have-it- all generation suddenly lose everything they own. But in the bitterness that accompanies hardships are lessons worth savoring-and，if you look hard enough，sweet opportunity.

Next，you'll learn how the brain responds to failure and how it can be reprogrammed for success using some simple tricks. You'll also find advice from a successful entrepreneur(企业家)who claims that times like these are actually among the best for launching dreams. But most valuable，you'll meet some ordinary people who were in some tough situations. A few cheered up; others got depressed. But even though their stories are quite different，the outcomes are the same. They all bounced back. And you can too.

As Bowling herself would admit, it doesn't take a wizard(奇才)to do it.

In many parts of the world，cars play an important role in daily life and many societies would not exist without them.So the idea that in 20 years’ time, no one will own cars may be hard to believe.But this is the prediction made by a team of transport researchers who are taken seriously, not only by government but also by ear manufacturers.

The Human Science and Advanced Technology Institute at Loughborough in the UK is part of an international research program.The team there believes that by 2020 all cars will be computerized，which will mean much saving，no accidents and better use of roads.The superintelligent car of the 21st century will drive itself, and it will not be owned by one individual.Instead，we will have a choice of cars and change them as frequently as we change our clothing.

According to Dr.David Davis，who leads the research team，these predictions are based on the rising cost of the car culture，which had blocked up our cities，polluted our air, and caused more deaths than both world wars put together.

Davis says，cars will be fitted with some intelligent devices to regulate the distance between one car and another.The car will automatically speed up，or slow down，to match the speed of the car in front.Computers are much safer drivers than people，so cars in a road train will be able to drive much closer together than cars driven by people.

By 2010，Dr.David Davis believes，car technology will give motorists a clear view of the road，whatever the weather conditions，by projecting an image of the road ahead on to the car’s windscreen.And by 2020，cars will travel in_convoy,_linked to each other electronically.Cars will be connected by an electronic tow bar to the car in front to form “roadtrains”．“The front vehicle in such a train burns the normal amount.”says Davis.“But all the others in the train would burn about ten percent of the normal amount，and so produce about ten percent of the pollution.”

1.Which of the following will be the characteristic of the cars of 2020?

A. The car will speed up out of control.

B. We will own as many cars as we want.

C. All cars will be driven by computers.

D. Cars will produce more pollution than present ones.

2.The leader of the research team believes that the present car culture will change because________.

A. cars play a very important role in daily life

B. many societies would stop functioning without cars

C. cars should not be owned by one individual

D. it causes many deaths to human society

3.The expression closest in meaning to the phrase “in convoy” in the last paragraph is________.

A. in line B. sidelong

C. side by side D. shoulder to shoulder

4.What will happen if cars are joined to each other electro- nically in 2020?

A. Motorists will get a clear view of the road.

B. There will be less pollution caused by car.

C. The weather condition will not have effect on motorists.

D. All trains will bum less fuel than present.
