题目内容
【题目】A lot of people are interested in sea animals, especially the ones that are beautiful and smart. Although some are wild, and can be deadly, each is also unique in its own way.

There are about 32 types of dolphins that live in salt water, each unique in its color and body shape. Five other types live in fresh water.

Seasons in which fish are abundant are like party time for dolphins. Dolphins decide how much they are going to eat based on the fat content of the fish available. They’ve a good sense of understanding about their hunger.

【解析】试题分析:文章主要讨论海洋动物——海豚。讲述了海豚的进化,饮食习惯以及海豚的社交技能和智慧。
【1】推理判断题。根据第一段“Whales, sharks and dolphins are the main subjects of sea-animal research, with dolphins standing out from whales and sharks for their friendly behavior with humans.”可知,海豚因为其不同于其它海洋动物的对人们的友好行为,而成为海洋研究的主要话题。故选A。
【2】词句猜测题。根据上文The debate on the origin of the dolphin is an unending one, however.可知,对于海豚的起源的辩论一直是一个没完没了的话题,下文讲述一些人认为他们是从有蹄的哺乳动物的进化来的,其他人认为它是数百万前从其它的哺乳动物进化来的。因此推断they指海豚。故选B。
【3】细节理解题。根据第二段You may be surprised to learn that they are close relatives of camels and cows.可知,海豚与骆驼有密切联系。故选C。
【4】段落大意题。通读第三段可知,成年海豚每天吃差不多20到22公斤鱼,海豚的饮食习惯取决于他们生活在哪里以及季节,海豚根据可食用的鱼的脂肪含量来决定它们要吃多少,他们对饥饿有很好的感觉。因此推断本段主要讲述海豚的饮食习惯。故选D。
