题目内容
14.We were enjoying watching the football match on TV the electricity went out.( )A. | then | B. | as | C. | while | D. | when |
分析 我们正在享受观看电视足球比赛,正在这时忽然电停了.
解答 答案:D.根据选项 when当…时,正在这时,while当…时,尽管,然而(前后对比),as 表示"一边.一边,再结合句意:正在这时忽然电停了.可知此处缺少了一个引导时间状语从句的连接词,故D正确,be doing…when为固定结构"正在做某事,忽然…",be about to do…when…正要做某事,忽然;when=at that time
点评 本题考查时间状语从句的连接词,连词的辨析要根据上下文的语境进行,要特别注意一些连词的一词多义现象.如本题的when=at that time
