Without gravity, we _____ walk on the ground as freely as we do now.

A．couldn’t

B．mustn’t

C．shan’t

D．needn’t

答案

解析

试题分析：考查情态动词：A. couldn’t 不能B. mustn’t 禁止C. shan’t 不该D. needn’t不必，句意：没有重力我们就不能象现在这样自由地在地面上行走。选A。
点评：这题主要是情态动词的用法，情态动词主要从词义和语气判断，所以在具体的语境中要注意选用恰当的词语。这里考查的是情态动词的否定的用法：注意肯定和否定含义的差别，如：must是必须，mustn’t是禁止。
