To most of us sharks are the most dangerous fish in the sea and they attack humans. However according to Dr. Clark who has studied the behavior of sharks for 12 years, humans are not normally on a shark’s menu. What do sharks feed on? Mainly fish and other small sea animals. Dr. Clark also found that sharks don’t eat as much as people think. For instance, a 9-foot shark only needs 2 pounds of food a day to keep healthy. But she says sometime sharks starve and the other times they feed themselves with what they have killed.
Around the world there are only about 100 shark attacks on humans each year ten of which prove fatal. But consider this, in the U.S. alone, about 3 million people are bitten by dogs each other. Of these, thirteen people died. "If shark bites you", says Dr. Clark, "The reason is usually because it mistakes you for its natural food." For example, say you when underwater fishing and saw a shark, you could be in trouble. The shark might go for the injured fish you had attacked and take a big bite at you at the same time. If you go into a sharks’ territory and threaten it ,it might try to bite you. because sharks are territorial and tend to guard their territory. Like dogs, they protect the area the think is their own.
选项
A、They are not as dangerous as people think.
B、They can be as friendly to humans as dogs.
C、They attack human beings by nature.
D、They are really tame sea animals.
答案
A
解析
细节明示题。文章提到了狗,但不是作为朋友提到的,可以排除B;从文章所叙述的鲨鱼在什么情况下才会攻击人来看,鲨鱼攻击人类并非出于本性,C可以排除:文章开始提到人们一般都认为鲨鱼很危险,而正文又介绍鲨鱼在很多情况下对人并无威胁,所以答案为A,即本文试图说明鲨色并不是如人们所想象的那么可怕。
