Great white sharks! Just hearing that name makes many people’s hair stand on end. In reality, these big fish have more to fear from us than we do from them. For many years, people killed countless great white sharks in the waters around the United States.

But thanks to conservation (保護) efforts, great whites are making a comeback in the U.S. Two recent studies show that the population of these sharks is rising along the east and west coast.

Why is the growing population of a killer fish something to celebrate? “When you fish too many of them, you start to lose balance in the environment,” says shark researcher Tobey Curtis. As the biggest killer, sharks help keep the populations of fish, seals, and other creatures they eat from growing too large.

In spite of their importance, great white sharks had long been hunted for their meat and their fins (鰭). Then, in 1997, the U.S. government passed a law that didn’t allow the hunting of great whites.

Afterwards, the numbers of these sharks in the U.S. waters started to increase.

The law wasn’t the only thing that has helped great whites. Conservationists have also played a part

in the sharks’ comeback. The research group OCEARCH is using a method called tagging (加標(biāo)簽) to help change people’s attitudes about great white. They let the public follow each shark as it travels the world’s oceans. OCEARCH also gives each tagged shark a name to help people form a closer connection with the big fish.

The group’s most well-known shark is named Katharine. She was tagged last year near Cape Cod, Massachusetts. Since then, thousands of people have tracked Katharine’s movements on Twitter and the

OCEARCH website.

This helps people see sharks in a new way. Chris Fischer, the founder of OCEARCH believes

learning to appreciate great whites will encourage people to do more to protect them.

1.The underlined part “makes many people’s hair stand on end” in Paragraph 1 can best be replaced by______.

A. worries many people B. bores many people

C. frightens many people D. interests many people

2.The law passed in 1997 ______.

A. seemed very helpful B. let scientists down

C. needed to be changed D. made people like great whites

3.Katharine’s example is used to show that ______.

A. great whites are in fact lovely animals

B. the OCEARCH website has a lot of visitors

C. the number of great whites is growing quickly

D. OCEARCH help people get closer to great whites

4.The main purpose of the passage is to ______.

Some people think that success is only for those with talent or those who grow up in the right family, and others believe that success mostly comes down to luck. I’m not going to say luck, talent, and circumstances don’t come into play because they do. Some people are born into the right family while others are born with great intelligence, and that’s just the reality of how life is.

However, to succeed in life, one first needs to set a goal and then gradually make it more practical. And, in addition to that, in order to get really good at something, one needs to spend at least 10,000 hours studying and practicing. To become great at certain things, it’ll require even more time, time that most people won’t put in.

This is a big reason why many successful people advise you to do something you love. If you don’t enjoy what you do, it is going to feel like unbearable pain and will likely make you quit well before you ever become good at it.

When you see people exhibiting some great skills or having achieved great success, you know that they have put in a huge part of their life to get there at a huge cost. It’s sometimes easy to think they got lucky or they were born with some rare talent, but thinking that way does you no good, and there’s a huge chance that you’re wrong anyway.

Whatever you do, if you want to become great at it, you need to work day in and day out, almost to the point of addiction, and over a long period of time. If you’re not willing to put in the time and work, don’t expect to receive any rewards. Consistent, hard work won’t guarantee you the level of success you may want, but it will guarantee that you will become really good at whatever it is you put all that work into.

1.Paragraph 1 mainly talks about ______.

A. the meaning of success B. the reasons for success

C. the standards of success D. the importance of success

2.Successful people suggest doing what one loves because ______.

A. work makes one feel pain B. one tends to enjoy his work

C. it takes a lot of time to succeed D. one gives up his work easily

3.What can we infer from Paragraph 4?

A. People sometimes succeed without luck or talent.

B. Successful people like to show their great skills.

C. People need to achieve success at the cost of life.

D. It helps to think that luck or talent leads to success.

4.What is the main theme of the passage?

A. Having a goal is vital to success.

B. Being good is different from being great.

C. Luck, talent and family help to achieve success.

D. One cannot succeed without time and practice.

A 15-year-old boy planned to put a ball covered with petrol into his mouth and set it on fire. He would film the dangerous action and put it on YouTube. And, lie hoped to become famous on the Internet. But things didn’t go the way he imagined. His clothing caught fire, and he was rushed to the hospital with serious bums on his body.

YouTube hosts millions of videos of people attempting dangerous actions. Many of them are by kids and young adults. Some experts say that by hosting these videos, YouTube encourages young viewers to take deadly risks. Research by the Centers for Disease Control and Prevention shows that more than 180,000 Americans die from accidental injuries each year. That’s one person every three minutes. More than 14,000 of those killed are kids under the age of 19. Is YouTube to blame?

People have always found it interesting to watch others try risky things. Audiences love these kinds of things. Some of the earliest Greek comedies had characters followed by wild animals and knocking into walls. Now, in the age of the Internet, anyone with a camera and a YouTube account can create this kind of “fun”. Many viewers, especially teenagers, are influenced by what they see and want to try it themselves. “YouTube has taken the playing in the neighborhood to a worldwide level,” says Clair Mellenthin, a researcher from the Centers.

Supporters of YouTube argue that it isn’t YouTube’s responsibility to examine its content. “Parents should be the ones to make sure that kids are behaving safely,” they say. In fact, YouTube has a rule on content. For example, dangerous activities that have a risk of serious physical harm or death are not allowed. Staff of YouTube, carefully watch the website 24 hours a day, looking for videos that are against their rules. But is this enough?
