The inner connection for the entire area _____when there was a sudden power cut
题型：不详难度：来源：
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
| B |
解析
试题分析：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。 |
