3. 现在完成时、过去完成时与将来完成的区别
(1) 现在完成时以现在时间为参照点，表示在“现在”以前完成的动作或持续到“现在”的状态；过去完成时则以过去时间为参照点，表示在“过去”某一时间以前发生的动作或持续到“过去”某一时间的状态；将来完成时则以将来时间为参照点，表示在“将来”某一时间为止已经完成的动作或持续到“将来”某一时间的状态。如：

18．D
【详解】考查动词时态。句意：到Mike从军队退役的时候，他的儿子将已经从大学毕业了。根据句意可知，本句是在说一件将来的事情，而从句谓语retires是一般现在时态，根据状语从句表将来时，主将从现的原则，所以主句要用一般将来时。而当有by the time…这样的时间状语时，句子一般用完成时态，所以本句应该使用将来完成时态：will have done。故选D。
19．D
【详解】考查时态。句意：——你的报告做得怎么样了？——差不多准备好了，我将做完所有我该做的。分析句意可知，我还没有完全准备好，所以后一句应用将来完成时，表示在将来会完成所有应该做的，主语为第一人称则由shall引导。故选D项。
20．D
【详解】考查时态。句意：每当我想到有一天我将实现我的目标，我是如此的幸福，我开始哭了。根据句意可知，我的目标还没有实现，而且是我想象实现了的那一天，由此可知，此处用将来完成时。故选D。
【点睛】将来完成时的考查要求考生非常细心，首先要判定发生在将来，而且将来的某个时间已经完成，考生需通过一定的时间状语和语境来判定使用该种时态。题根据句意可知，我的目标还没有实现，而且是我想象实现了的那一天，由此可知，此处用将来完成时。
21．C
【详解】考查时态和语态。句意：你们彼此之间最好真诚地沟通，我希望明天你们的冲突能得到解决。由时间状语tomorrow可知，此处应用将来时，conflict和solve之间为被动关系。因此C项的将来完成时符合语境，表示在将来某一时间以前（明天结束之前）已经完成的动作。故选C项。
22．A
【详解】考查动词时态。句意：当你养成管理时间的习惯时，你就会对如何在未来的职业生涯中利用时间做出更好的决定。在by the time引导的从句中，如果从句中的谓语动词为一般现在时/或现在完成时（表示将来），那么主句中的谓语动词常为将来完成时，表示“截止到将来某一时间为止，主句动作将已经完成”。故选A。
【点睛】by the time用法辨析
1、 如果从句中的谓语动词是一般过去时，那么主句中的谓语动词通常用过去完成时，表示“截止到从句动作发生时，主句动作已经完成，即过去的过去”。
2、如果从句中的谓语动词为一般现在时/或现在完成时（表示将来），那么主句中的谓语动词常为将来完成时，表示“截止到将来某一时间为止，主句动作将已经完成”。
3、如果主句动作不强调已经完成，只是说明某个时候的状况，（主句是be的系表形式或者是表示像know, find, believe等表示认知的持续性动词，则往往用一般时态，不用完成时态。）此时主句不用完成时，而应根据实际需要选用适当的时态，此时by the time相当于when。

1、 如果从句中的谓语动词是一般过去时，那么主句中的谓语动词通常用过去完成时，表示“截止到从句动作发生时，主句动作已经完成，即过去的过去”。
2、如果从句中的谓语动词为一般现在时/或现在完成时（表示将来），那么主句中的谓语动词常为将来完成时，表示“截止到将来某一时间为止，主句动作将已经完成”。
3、如果主句动作不强调已经完成，只是说明某个时候的状况，（主句是be的系表形式或者是表示像know, find, believe等表示认知的持续性动词，则往往用一般时态，不用完成时态。）此时主句不用完成时，而应根据实际需要选用适当的时态，此时by the time相当于when。
