The mad man was put in the soft-padded cell lest he ____________ himself.
A、injure
B、had injured
C、injured
D、would injure
【正确答案】：A
【题目解析】：lest的意思是唯恐，以免，免得。它是连词。 它所连接的状语从句里常用should或原形动词，意思:以免; 生怕; 唯恐 ，这是虚拟语气例如:Be careful lest you fall from that tree. 要当心, 以免从树上摔下来。 I obeyed her lest she should be angry. 我得顺着她，免得她生气。 跟这个词同样用法的还有:in case(以防)和 for fear that(生怕，唯恐)
