It seems that no one can live a happy life without friendship. While a great number of people expect others to be their friends, they don’t give friendship back. That is why some friendships don’t last long. To have a friend, you must learn to be one. You must learn to treat your friend the way you want your friend to treat you. Learning to be a good friend means learning three rules: be honest; be generous; be understanding.

Honesty is where a good friendship starts. Friends must be able to trust one another. If you do not tell the truth, people usually find out. If a friend finds out that you haven’t been honest, you may lose your friend’s trust. Good friends always depend on one another to speak and act honestly.

Generosity means sharing and sharing makes a friendship grow. You do not have to give your lunch money or your clothes. Naturally you will want to share your ideas and feelings. These can be very valuable to a friend. They tell your friend what is important to you. By sharing them, you help your friend know better.

Sooner or later everyone needs understanding and help with each other. Something may go wrong at school. Talking about the problem can make it easier to solve. Turning to a friend can be a first step in solving the problem. So to be a friend you must listen and understand. You must try to put yourself in your friend’s place so that you can understand the problem better.

No two friendships are exactly alike. But all true friendships have three things in common. If you plan to keep your friends, you must practice honesty, generosity and understanding.

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.
