It______about seven o’clock when Tom returned home for it was already dark outside.
选项
A、must be
B、must have been
C、was to be
D、had to be
答案
B
解析
本题考查情态动词。must在表示对现在的状态或现在正在发生的事情进行推测时,后面通常接系动词be;表示对已经发生的事情进行推测时,must后面要接完成式。本题中,由原因状语从句it was already dark outside可推知,事情发生在过去的时间,因此谓语需要使用“must+完成式”的结构,故确定本题的答案为B)。
