题目内容
16.---Hello,Lisa.What's the matter?I _________ find my mobile phone._________ you seen it?( )
| A. | couldn't; Did | B. | can't; Have | C. | need; Had | D. | must; Are |
分析 --嗨,丽莎.你怎么了?
--我找不到我的手机了.你见到过吗?
解答 答案:B.根据you seen it,可以推测前面句子的意思应该是我找不到手机,这个句子应该是否定的意思.这里询问的应该是现在的情况,所以答语所使用的时态应该是一般现在时,而couldn't是过去时形式,所以选项A不对,排除掉,选项CD这里是肯定句,不符合题意.seen在这里是过去分词形式,所以前面只能是have或had,你见到过吗,询问的是现在的情况,用现在完成时.故选B.
点评 本题考查了情态动词的用法.熟知句意是解答本题的关键.
