Sharks help keep our oceans healthy
Many people think of sharks as dangerous animals. But humans do more harm to these animals than they do to us. Although shark attacks do happen, they are quite uncommon. On the other hand, according to one survey, humans kill 100 million sharks every year. This survey is warning that many kinds of sharks may become extinct.
The killing of sharks is a problem for the whole planet. Sharks are killers, which means that they eat other species, but that few animals eat them. As sharks die off, the populations of the animals that sharks eat will increase. That includes some sea animals that humans eat, such as fish. Smaller shark population affects more than just the ocean. Ocean plants produce much of the oxygen on the planet. These plants can be harmed when changes in the shark population upset the ecosystem.
Don't use shark products. Shark liver oil is used in may popular cosmetics(化妆品).pet foods, vitamins, energy drinks and leather goods can also be made from shark parts. And shark meat is sold around the world, sometimes under misleading names such as rock salmon or whitefish. Most sharks killed worldwide are only killed for their fins, which are used to make shark fin soup. The process is terrible: Fishermen cut the shark's fins off and then throw the shark back into the water, still alive. Then the shark dies slowly, sometimes over several days. Sharks breathe by swimming, so a shark that can't swim will die.
Sharks often die because they become tangled(缠绕)in nets for catching other kinds of fish. If you eat seafood, make sure it comes from right fisheries that care for the oceans. Many organizations try to protect sharks. They can teach you about these animals and give more advice on how to keep them alive. These organizations also need your support to continue protecting these important animals.
( )1. What does the underlined word "extinct" mean in English
A.Left B.Reached C.Started D.Ended
( )2.Why should we save the sharks
A.To protect other sea fish.
B.Tow grow more sea plants.
C.To protect the ocean ecosystem.
D.To deal with climate change.
( )3. What's;the writing purpose of Paragraph 3
A.To show us how sharks die.
B.To ask us to catch more sharks.
C.To ask us to make shark products.
D.To ask us to stop using shark products.
( )4. What is TRUE about the passage
A.We can't eat any seafood at all.
B.We can't do anything to save sharks.
C.We can eat some seafood from right fisheries.
D.We can raise sharks with the help of scientists.
( )5.In which section of a magazine can you read the text
A.Health and sports.
B. History and culture.
