此刻达成时（ 1）组成：在达成由助have +去分组成，助 have 有人称和数的化。

第三人称数用has，其他用 have.not、疑式是把助提到主以前。

以 study 例，其否认式、在达成的否认式直接在助后边加上疑式和回答形式以下：否认式疑式I have not (haven’ t) studied⋯.Have I studied⋯?You have not (haven’ t) studied⋯.Have you studied⋯?He has not (hasn’ t) studied⋯.Has he studied⋯?否认疑式回答（一定 /否认）Have I not (Haven’ t I) studied⋯?Yes, you have.

结合语境可知上文描述的是现在已经完成的动作，故用现在完成时态。

选C。

【点评】英语中的时态主要是借助于时间状语与上下文语境来进行判断。

解答此类题型，首先要注意句子中的时间状语，如果没有则要通过分析上下文，结合语境来判断句子的时态。

英语疑问句中一般具有时态上的对应关系，注意结合这一特点进行区分。

由since可知but后的主句用现在完成时，瞬间动词fall不能和since引导的时间状语从句连用，故用延续性动词be。

故选D。
