   Sharks(鲨鱼) are not as dangerous to humans as humans are to sharks. Even though millions of people swim in the seas each year, fewer than fifty serious shark attacks appear usually, and only ten of these are fatal (致命的). The reason for this low accident rate is that most sharks are afraid of living things as large as humans. Of the350 known kinds of sharks, only one — the great white shark — is totally unafraid of humans. At the same time, humans kill sharks in greater numbers than in the past. Thousands are hunted and killed each year for foodThousands more are killed by the nets under the water, which are put off the beaches to protect swimmers in Australia and South AfricaEven the great white shark is reducing as humans hunt it for its teeth, which are sold to collectors. Maybe it is time we began worrying less about protecting people from sharks and more about protecting sharks from people.

1. The passage mainly tells us that ________.

Ait doesn’t matter if a person is attacked by a shark

Bsharks are not as dangerous as people think

Csharks are afraid of things the size of a human

Dthere are fewer shark attacks than before

2. Nets are put off the beaches in some countries so that ________.

Aswimmers will be safe on the beaches

Bpeople can kill more dangerous sharks

Cpeople can catch sharks easily

Dsharks will not be attacked

3. By writing this passage, the writer wants to give us a warning that ________.

Athe nets off the beaches are killing too many sharks

Btoo many people want to collect shark teeth

Csharks are in danger

Dsharks are still dangerous

  Sydney-A shark savaged a schoolboy's leg while he was surfing with his father at a beach in Sydney on February 23.It was the third shark attack along the coast of Australia's largest city in a month.

  The 15-year-old boy and his father were in the water off Avalon, on Sydney's northern beaches, around dawn when he was attacked.The city's beaches are packed with locals and tourists during the summer months.

  “The father heard a scream and turned to see his son trashing(扭动)about in the water,”police said.“Fortunately, the shark swam away and the boy was helped to shore by his father.”

  Lifesaving Club spokesman Nick Miller said,“It got him around the top of his left leg and the father came and dragged his out of water.”He said the boy was bleeding heavily when he was brought to the shore.“There was a lot of pain, as you can imagine.”The teenager was airlifted to hospital for treatment for leg injuries.

  Police said the bites“cut through to the bone”, but the boy did not appear to have sustained any fractures(骨折).He was in a stable condition now.

  Several beaches were closed after the attack.Water police and lifeguards were searching for the shark, while police hoped to identify its species by the shape of the bite marks.But they said it was too early to say what type of shark attacked the boy.“I don't even know if he saw it,”Miller said.

  Many shark species live in the waters off Sydney's beaches, but attacks on humans are still relatively rare.However, there were two attacks on successive days earlier this month, one on a navy diver in Sydney harbor, not far from the famous Opera House, and the other on a surfer at the city's world-famous Bondi beach.

  Fishermen say shark numbers are on the rise.There is a ban on commercial fishing in the harbor, which has increased fish stocks.Marine experts also claim environmental protection has created a cleaner environment, attracting sharks closer to the shore as they chase fish.Many shark species, including the Great White-the man-eaters made famous in Steven Spielberg's Jaws-are protected in Australian waters.

  The NBA’s version of the Ming Dynasty is done.After helping basketball gain a foothold in the world’s most populous market, Chinese star Yao Ming has retired.

  Yao made it official Wednesday, telling a news conference that a series of foot and leg injuries forced him to end his playing career at the age of 30.

  “I will formally end my career,” said Yao, who became a household name in China before starting his NBA career with the Houston Rockets in 2002.Yao played eight seasons in the NBA.

  “Today is an important day for me and holds a special meaning for both my basketball career and my future,” Yao said.“I had to leave the court since I suffered a stress fracture(断裂) in my left foot for the third time at the end of last year.My past six months were a painful wait.I have been thinking about my future over and over.Today I am announcing a personal decision, ending my career as a basketball player and officially retire.But one door is closing and another one is opening.”

  Yao said he would return to work with his former Chinese team, the Shanghai Sharks, with the possibility of becoming general manager.He already owns the club and wants to contribute more.

  “My playing career started with the club.I hope I can do something for it,” Yao said.

  Rockets general manager Daryl Morey was among those attending the farewell(告别) conference Wednesday.Morey made the long trip from Houston.Morey said 20 hours on planes was tiring but he would be sorry if he wasn’t here.“It’s a big moment,” Morey added.“Yao had a sense of humor, a great attitude and sense of responsibility.I hope we can continue his culture in the NBA.”

  Yao had played six years with the Chinese national team before joining the Rockets, and was already a star in his home country.He carried the Olympic torch through Tiananmen Square and his country’s flag during the opening ceremonies at the Beijing Olympics in 2008.He also donated $ 2 million and set up a foundation to rebuild schools in the wake of the 2008 earthquake in Sichuan.

To support the recent Earth Day, a small group of HELP University College students from the

Greens Club, a nature society, did their bit for the hard situation of an unlikely mistreated group: sharks (鲨鱼). 

Nearly 100 million sharks are killed every year for their fins (鳍),which are made into shark fin soup that is referred to as the delicacy.

Some members of the club spent one month gathering research materials for a show. “I thought I already knew how sharks were treated—I never thought it could be so cruel,” admitted Hui zhi, who helped set up the “shark murder” TV corner for the club and was one of the first to watch the video materials. “It’s very beneficial to anyone who watches it”, said Clarence meanwhile. “And watching it probably does a lot to get people to stop eating shark fin soup and stop the demand for it.” He is right. Watching the poor sharks killed at the hands of human is not different from watching one’s beloved household pet killed unmercifully(无情地) just for something God gives them, like fins, or fur.

“Young people can influence their parents’ thinking. We wanted to screen Shark Tale to show the human side of sharks, the human side that every animal has.” added Ee Ling, who founded the Greens Club three years ago.

Fortunately, there is the good sense of young hearts and minds like Ee Ling and friends who are able to see and value the soul in natural things before they become exploited (不正当地利用) for our own pleasure.                                                                            

1. Why are so many sharks killed every year?

  A. People hunted them for their fins.      

B. Because they are dangerous to fishermen.

  C. Because people want to screen “Shark Tale”.

  D. Because they are not like our beloved pets.

2. Form the passage we can infer that______.

  A. shark fin soup is the best delicacy in the world

  B. people who watched the video materials about sharks would stop eating shark soup at once

  C. people don’t like sharks

  D. many people aren’t able to see and value the soul in natural things

3. How does the writer feel about the present situation?

  A. depressed   B. angry     C. sad but hopeful    D. disappointed
