Urban swans might be born with a daredevil gene that makes them less fearful of humans, compared with their rural colleagues.

A study has found swans living in cities tend to be bolder and it is at least partly determined by a gene called DRD4. Birds with this gene could therefore be better adapted to settling in more populated areas, while more timid(胆怯的)swans would escape to less inhabited regions.

It could help to explain why swans in public parks and on urban rivers have a reputation for being so aggressive towards humans - they are simply not afraid of us.

Biologists from some universities in Australia, tracked and collected blood samples from black swans living in two wetlands near cities. One group of swans lived in a recreational urban park, while the other occupied a waste-water processing site out of town. The two areas were less than 20 miles apart. Later, from 2011 through 2013, the researchers started systematically scaring the swans at both sites. The researchers approached the birds and calculated how close they could get before they flew away. As expected, they noticed that while rural swans started flying away if a human was closer than 119 meters, the scientists could come as close to urban swans as 39 meters before taking off.

Analyses of the blood samples, in fact, showed that 83 per cent of the less cautious swans presented the same genetic DRD4 variation(变异)while rural swans have different genetic makeups resulting in more wariness(谨慎,小心).

The researchers conclude that swans with the bold variation of the gene might choose to live in urban environments, as they tend to be less bothered by human presence.

1.The underlined word in paragraph 1 means__________.

A. timid B. cautious

C. bold D. stubborn

2.What’s the difference between rural swans and urban ones?

A. The rural swans carry more DRD4.

B. The urban swans are more friendly.

C. The urban swans are less scared of people.

D. The rural swans are aggressive towards humans.

3.What does DRD4 refer to ?

A. a kind of blood. B. a kind of food.

C. a kind of genetic variation. D. a kind of swan.

4.What does the 4th paragraph mainly talk about?

A. The living habit of swans.

B. The living environment of swans.

C. The contribution of the biologists.

D. The process and result of the research.

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.
