题目内容
18．-Marry，it seems you don't quite understand what we are talking about？-Sorry，I____ of something else just now．（ ）
| A． | have thought | B． | had thought | C． | thought | D． | was thinking |
分析 --Mary，好像你不是很理解我们正在谈论的事情．
--抱歉，我刚才在考虑别的事情．
解答 答案：D．
结合上句的意思""Mary，好像你不是很理解我们正在谈论的事情．，判断答语中设空处的意思是"我刚才在考虑别的事情．"，动作在过去某个时刻正在进行着，且动作在一段时间内持续进行，所以用过去进行时，过去进行时的构成是：主语+was/were+动词的现在分词，故选D．
点评 本题考查了动词的时态．做题时，一定要特别关注有关的时间短语，这是判断句子时态的标志．在没有时间状语的情况下可以联系上下文根据状语从句的类型来做出正确判断．
