答案
D 试题分析:现在完成时用来表示之前已发生或完成的动作或状态,其结果的确和现在有联系。动作或状态发生在过去 但它的影响现在还存在;也可表示持续到现在的动作或 状态。其构成: have (has) +过去分词。根据语境可知此句的含义是楼下有很多的人,你认为发生什么事情了,因主语是what, do you think是插入语,故用助动词has not+过去分词,故选D. |
解析
点评: 注意现在完成时和一般过去时两种时态的区分 (1)一般过去时的谓语动词用过去式,而现在完成时的谓语基本构成是"助动词have /has +过去分词"。 (2)一般过去时通常与表示过去的时间状语连用。如:yesterday, last week, two years ago, just now, in 2002等; 而现在完成时则常与just, already, ever, never等副词和these days, this week, since..., for...等表示一段时间的状语连用。 |
