题目内容
10.昨天这个时候你在干什么?What were you doing at this time yesterday?
分析 What were you doing
解答 答案:What were you doing.结合at this time yesterday可知表达的是过去正在进行的动作,故用过去进行时was/were+doing,这里是特殊疑问句,特殊疑问词what,主语you,故were,故答案是What were you doing.
点评 过去进行时(Past continuous tense或Past Progressive tense)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.
