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?

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(hù)) 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 ______.

A. introduce an experiment result

B. make an advertisement for OCEARCH

C. remind us that big killers are dying out

D. inform us that great whites are making a comeback
