题目内容
11.While Helen _______ the piano,her mother came in.( )| A. | was playing | B. | is playing | C. | played | D. | plays |
分析 当海伦弹钢琴的时候,她的妈妈进来了.
解答 答案:A.结合while引导的时间状语从句,主句her mother came in可知是表达的是过去正在进行的动作,故用过去进行时was/were+doing,主语Helen,故was,故答案是A.
点评 表示过去在某一时间段或某一段时间内正在发生或进行的动作或状态.其形式为 主语+was/were+V-ing.常与表示过去的时间状语连用,如:last night,last Saturday等;或者与when,while,as引导的过去时间状语连用.例如:We were watching TV from seven to nine last night.昨天晚上七点到九点的时候我们在看电视.What was he researching all day last Sunday?上周日他一整天都在研究什么?
