问题 What is the main idea of the passage?
Which of the following description about the size of sharks is TRUE?

选项 A、Sharks are big animals, most of them are about 50 feet long.
B、Sharks are the largest fish, most of them are bigger than buses.
C、Most sharks are much longer than human beings.
D、Most sharks are about the same size as human beings.

答案D

解析 本题问“关于鲨鱼的尺寸,下列哪项描述”正确。文中相关部分在第三段,其中提到“Most sharks are intermediate in size,and are about the same size as people,5- 7 feet long.(大多数鲨鱼都为中等尺寸,即5到7英尺,和人体的长度基本一致。)”故[D]“大多数鲨鱼与人真的尺寸大致相同”正确。[A]“鲨鱼是大型动物,大多数鲨鱼身长约50英尺”文中提到成年鲨鱼的长度从7英寸到50英尺不等,50英尺属于鲨鱼中最大的尺寸,而不是大多数鲨鱼的尺寸。[B]“鲨鱼是体型最大的鱼粪,大多数鲨鱼比公共汽车体积大”文中提到从人的手掌大小到比公共汽车还大的鲨鱼都存在,不能认为大多数鲨鱼的体积都比公共汽车大。[C]“大多数鲨鱼比人真的身长长很多”文中提到大多数鲨鱼的长度与人体的长度基本一致,本选项与文中的陈述相反。
