初中英语综合库阅读还原练习题及答案

In sunny California, Craig Rogers was sitting on his surfboard, scanning the distance for his next wave.     1     He looked down and was scared to see a great white shark biting the front of his board. “I could have touched its eye with my hand,” says Rogers. The shark had surfaced so quietly that he didn’t hear a thing. In his horror and confusion(慌乱), he waved his arms and accidentally cut two of his fingers on the shark’s teeth.     2     Then, although Rogers being in the water with blood flowing from his fingers, the five-meter-long shark simply swam away.

    3     Of these, one-third are said to be great white attacks. Great whites are often described as “man-eaters”—creatures that hunt and kill humans—but this is factually incorrect.     4     In fact, a person has a greater chance of being killed by lightning than by a great white.

One of the most common explanations for great white attacks is that great whites don’t see well. It is thought that they often mistake a person for a seal or a sea lion—a very attractive snack. Some other shark researchers believe that great whites “attack” because they are actually curious animals that like to study things. They believe that it’s possible great whites use their bite not just to kill and eat, but also to gather information.     5     Even though such experiences are unlucky for people like Craig Rogers, perhaps when sharks bite surfboards, other objects, or even people, they are just trying to learn what they are.
