题目内容

A. didn’t hear from B. don’t hear from
C. won’t hear from D. haven’t heard from
D
【解析】
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自从史密斯先生来到上海我从来没有受到他的来信。因主语是I,故用助动词have not+过去分词,故选D.
考点：现在完成时的基本构成和用法.
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。
