答案：
1.A
译文：等他到北京的时候，我们已经在这呆了两天了。
本句是将来完成时用法。将来完成时表示在将来某个时间之内业已完成的动作。通常由by (the time)连接的短语或句子引导。
2.A
译文：她应该停止工作，因为看书的时间太长，所以她头痛。
本句是现在完成进行时的用法。现在完成进行时可用来表示一个动作从过去某时开始，一直延续到说话时刻还在继续或刚刚结束。常与表示一段时间的状语连用，如：for two years, these few weeks, since early morning 等。从句中可以推断，看书是从过去某个时间开始一直延续到现在。
3.D
译文：“今晚5点我能和你的经理威廉先生通话吗？” “对不起，到时威廉先生早就开会去了。”
本句是将来完成时的用法。将来完成时表示将来某时刻之前或某一行为发生之前所完成的动作，常和by或by the time等结构连用。从本句来判断，到5点之前(将来某时刻之前)威廉已经去开会了(动作已经完成)。
- We're having a conference and we'd like you to sit in.我们将举行一次会议，希望你来旁听。
- The conference will come to a close this afternoon.今天下午会议闭幕。
