C. READING COMPREHENSION
We know that every year less than 100 people are attacked by sharks and about 5 to 10 of these people die. But, let’s look at the other side of the story – How many sharks do people kill? Well I think you already know this: People kill many more sharks. Every year, people hunt and kill thousands of sharks. One reason people kill sharks is for sport; they hunt them just for fun. Some people started to have contests to see who kill the most sharks or he bigger sharks. Another reason that people kill sharks is for food. In some countries, such as the United States and Great Britain, shark meat is a popular food. In other countries, such as China, people use shark fins to make soup. Because so many people like to eat shark, fishing boats catch a lot of sharks to sell for food.
So, for both of these reasons, people are killing many sharks. Some biologists are getting worried that the number of sharks is getting too small. That’s why many biologists think we should stop killing so many sharks, and instead try to protect them – or else some day they may all be gone. Some countries have already passed some laws to help protect sharks. The United States, for example, has passed laws that limit the number of sharks that people can kill or food or for sport. So even though some people like to hunt sharks, we do need to protect them.
