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。
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。
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。

7，(C) until引导的时间状语从句用了一般现在时表示将来的意思，主句因此必须用一般将来时与之呼应，口语中常用将来进行时代替一般将来时表示预料即将发生或肯定发生的事，也可表示某件事已经决定了。本句完全可以用will go 因此，正确答案是(C)。 ·
8．(C) by the time引导的时间状语从句中若谓语动词用现在时，则主句要用将来完成时；若谓语动词用过去时，则主句要用过去完成时，有时也可以用过去将来完成时。这样，本道题目的正确答案是(C)。
