　　答案与详解 ：

　　1.(D) 根据时态一致的原则，间接引语(或宾语从句)的时态应与主句的时态一致。该句中said是过去时所以that引导的宾语从句中也要用过去的某一种时态，而从句中since引导的时间状语从句表明其应为完 成时态，故应用过去完成时态。

　　2.(C) 通过上下文可以判定Ali看起来很难受很伤心，是因为刚才在进行的事情所导致的，所以用过去进行时较好，故(C)是正确答案。

　　3，(C) 根据句意和时间状语for twenty minutes，可以判断这里应填入现在完成时态，现在完成进行时是现在完成时态的强调形式，并且选项中没有现在完成时态，所以(C)是正确答案。

　　4.(A) 句意表明委员会是在调查事件之后才会做出决定，调查应发生在决定之前，所以应用将来完成时态，但是在英语中，时间条件状语从句中的将来完成时态是由现在完成时来表示的，所以正确答案是(A)。

　　5.(C) 从上下文的逻辑意义看，(C)项是唯一的正确答案。Carey没有参加晚会，原因是给她姐姐照看小孩子。而(A)和(D)表示对过去发生的事情根据客观情况作出主观推断：(A)作“准是看孩子了”讲;(D)作 “本应该看孩子”讲，都不对，而(B)表示动作发生在过去的将来，也不对，所以只有(C)正确。
