题目内容
12.Some villagers said that theyhad seen(see )UFOs many times before.分析 一些村民说他们以前看见过飞碟很多次.
解答 答案是had seen.本题考查语境中选用恰当的动词时态.过去完成时表示"过去的过去",表示某一动作或状态发生在过去某一动作或时间之前;本句中强调"see"发生在过去的动作"said"之前,故用过去完成时,答案是had seen.
点评 本题是要求用所给动词的适当形式填空,解题时首先考虑句中需要的是谓语动词还是非谓语动词;其次,如果是谓语动词关注时态、语态和数的变化;如果是非谓语动词要联系非谓语的基本用法判断非谓语的形式.
