Scientists say sharks have lived in the world’s oceans for millions of years. Scientists say there are more than 350 different kinds of sharks.
Sharks do not have bones, and a shark has an extremely good sense of smell. It can find small amounts of substances in the water, such as blood, body liquids and chemicals produced by animals. Sharks also sense electrical and magnetic power linked to nerves and muscles of living animals. These powerful senses help them find their food. Some sharks will eat just about anything. Many unusual things have been found in the stomachs of some tiger sharks. They include shoes, dogs, a cow’s foot and metal protective clothing.
About forty percent of the different kinds of sharks lay eggs. The others give birth to live young. Some sharks carry their young inside their bodies like humans do.
Scientists are beginning to understand the importance of sharks to humans. Medical researchers want to learn more about the shark’s body defense system against disease. They know that sharks recover quickly from injuries. Sharks appear never to suffer infections, cancer or heart diseases.
Questions:
29. What is this passage mainly about?
30. How can sharks find their quarries?
31. In which point some sharks are similar with humans?
32. Why are sharks useful for humans?
选项

B、Smell ability.
C、Birth mode.
D、Recover ability against disease.
答案
C
解析
细节题。该题问“鲨鱼的哪方面和人类相似?”出现“与人类相似”的原文的句子是:Some sharks carry their young inside their bodies like humans do.(一些鲨鱼就像人类一样在体内孕育后代.)所以答案是C。
