    The inner connection for the entire area _____when there was a sudden power cut yesterday.
    A．lostB．was lostC．had lostD．had been lost
    B

    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。
