Elephants have their own way to tell the shape of an object and _______ it is rough or smooth.A./ B.whether C.how D.what选A可以吗?

问题描述:

Elephants have their own way to tell the shape of an object and _______ it is rough or smooth.
A./ B.whether C.how D.what
选A可以吗?

选whether,选A不行.
选了A表示A and B结构,即“Elephants have their own way to tell the shape of an object”和“ it is rough or smooth”并列.翻译为:大象用它们自己的方式来分辨物体的形状和它是粗糙的或平滑的.就像两个不相关的句子联合在一起,而且it也指代不明.
正确句意是:大象用它们自己的方式来分辨物体的形状与是否粗糙或平滑.
whether.or.固定搭配
