问题 选择题

The inner connection for the entire area _____when there was a sudden power cut yesterday.

A.lost

B.was lost

C.had lost

D.had been lost

答案

答案:B

题目分析:考查时态:句意:昨天突然停电,我们失去了网络连接。lost 在这里做形容词用,丢失了,那么前边要有be动词来构成主系表的结构,when引导的时间状语从句是一般过去式,和主句的动作同时发生,所有前面要有was

点评:考查时态要抓住时间,这题有明显的时间状语:when there was a sudden power cut yesterday.所以很简单,再就是结合上下文。
