4. 句中范围限定是"of her life"，且有定冠词the，需要使用形容词big的最高级biggest，表达“最大的”含义。
5. 句中有范围限定"in the world"，且出现定冠词the，lovely的最高级形式为loveliest，表达“最可爱的”含义。

3. 本题考查固定短语，对应“在世界上”的常用短语是in the world，填入后符合句子语法和语义要求。

阅读理解
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.

1. 第1题：根据原文第一段第二句"They can think, understand and learn things quickly."可知人们认为海豚聪明的原因是它们可以思考、理解并且快速学习事物，其余选项内容原文均未提及，因此选B。
2. 第2题：逐一判断内容：①海豚和人类一样有专属的“名字”，第二段有对应表述，正确；②原文只提到海豚彼此交流，并没有提到它们可以和其他种类的动物交流，表述错误；③海豚和人类一样会在群体里玩耍，第三段有对应表述，正确；④海豚和人类一样会制定计划来获取自己想要的东西，最后一段有对应表述，正确。因此符合的是①③④，选A。
3. 第3题：第三段这句话的主语是海豚，句意为“它们群居，还经常加入来自不同群体的其他同类一起玩游戏、玩乐，就像人类一样”，这里的others指代的是其他的海豚，选D。
