Some people say dolphins(海豚) are smart like humans. They can think, understand and learn things quickly. Scientists say dolphins are like humans in some ways. How?
Like humans, every dolphin has its own “name”. The name is a special sound. Each dolphin chooses a special sound for itself at birth (出生时). Dolphins are like people in other ways too. They “talk” to each other about a lot of things—such as their ages and finding food. They also use sounds and body language to talk. Knowing dolphin words is not easy for humans. No one speaks dolphin words, but some scientists are trying to learn.
Dolphins are also social animals. They live in groups, and often join others from different groups to play games and have fun—just like humans. Scientists believe playing together is something that only smart animals do.
Both humans and dolphins make plans for getting the things they want. For example, when there are fish near a boat, dolphins jump high to ask the fishermen to put their nets, and then the fishermen can catch a lot of fish. Why do dolphins help the fishermen? Because they can get some fish that run away from the net.

答案

1. B

3. D
4. C
5. D

解析

1. 第一题题目询问为什么人们说海豚聪明。根据第一段第二句“They can think, understand and learn things quickly.”可直接确定B选项正确,其他选项未提及。
2. 第二题题目要求找出海豚和人类相似的方式。根据第二段“every dolphin has its own ‘name’”,第三段“They live in groups, and often join others...just like humans.”和第四段“Both humans and dolphins make plans...”可知①③④正确,选A。
3. 第三题题目要求确定“others”指代对象。根据第三段“They live in groups, and often join others from different groups...”的语境,主语是海豚,所以“others”指其他海豚,选D。
4. 第四题题目询问海豚帮助渔民的原因。根据最后一句“Because they can get some fish that run away from the net.”可知海豚通过这种方式获取食物,选C。
5. 第五题题目要求选择最佳标题。全文围绕海豚与人类的相似性展开,D选项“Dolphins Are Like Humans”最全面概括主题,其他选项片面。
