He bought a new dictionary last week.A. may lend you one B. might lend oneC. may lend this D. might be lending youStep2.“情态动词 + have + 过去分词”的用法：一、must + have + 过去分词 表示对过去发生的事情的肯定性推测，常用于肯定句中，意思为“一定是，肯定是”。如： She hasnt come yet. She must have missed her train. 她还没有来。她一定是没赶上火车。二、can/ could + have +过去分词1、表示对过去发生的事情的可能性推测，常用于否定句或疑问句中。如： He cant have been there. 她不可能去过那里。 The money has disappeared! Who could have taken it? 钱不见了，是谁拿了呢？表示“本来可以，差点就”，常用于肯定句中。如： I could have lent you the money.Why didnt you ask me? 我本来可以借这笔钱给你的，你怎么没向我借？ I could have died laughing. 我差点笑死了。三、may/might + have +过去分词 表示对过去发生的事情的可能性推测，常用于肯定句中，意为“也许已经，可能已经”。用might语气更为委婉或实现的可能性更小。如： Its five oclock now. She might have got home. 现在五点了，她或许已经到家了。 有时也可以表示轻微的埋怨或批评。如： They might at least have phoned if theyre not coming. 要是他们不来了，至少可以打个电话来嘛。四、ought to/should + have + 过去分词 肯定式表示“本该做某事而未做”；否定式表示“不该做却做了”，常含有责备的意味。如： You ought to have told me about it earlier. 你应该早点把这件事情告诉我。 You ought not to have taken away my dictionary without asking me. 你不该不问一下就把我的字典拿走了。 Its already nine oclock. You should have been here an hour ago. 已经9点了，你一小时以前就应该到这儿的。 They asy the movie was very good. We shouldnt have missed it. 他们说那部电影很不错，我们本不该错过的。五、neednt + have + 过去分词 表示过去不必做但实际上已经做了的事。如： The play didnt begin until 8 p.m. We neednt have hurried. 话剧晚上8点钟才开始。我们本来用不着那么匆匆忙忙的。Step 3.小露锋芒1、They _ the plane, or perhaps they have been prevented from coming for some reasons.A. can have lost B. may have lost C. can have missed D. may have missed2、Sorry，I am late.
