4、have（has）been to和have（has）gone to的区别
have（has）been to：去过某地（表示某人的一种经历），可以和once，twice，often，never，ever连用。
have（has）gone to：去某地了（表示某人已经离开此地，在去某地的路途上或已在某地，所以一般来说此句型只用于第三人称），此句型不能与上述时间状语连用。
（1）He has gone to America.（意思为他已经去了美国，现在不在此地）
（2）He has been to America twice.他去过美国两次。
1、表示在过去的某一时间或动作之前已经完成了的动作（即过去的过去）。这个过去的某一时间可用by, before等介词或连词引导的短语或一个从句来表示。
例：About the sixth century A.D. when few Europeans could read, the Chinese _____ paper.
A. invented B. had invented C. have invented D. had been invented（答案：B）
2、表示从过去某一时间开始，一直持续到另一个过去的时间的动作。
例：The chemistry class _____ for five minutes when we hurried there.
A. had been on B. was on C. has been on D. would be on（答案：A）
3、在含有before, after, as soon as等连词引导的状语从句的复合句中，由于连词本身可以明确表示动作发生的先后顺序，因此，主句和从句都可以用一般过去时表示，而不用过去完成时。
例：I called him as soon as I arrived.我刚一到就给他打 *** 。
4、过去完成时常用在no sooner…than…, hardly/scarcely/barely…when…，一…就…。句型之中，句子到装。
（1）No sooner had we sat down _____ we found it was time to go.
A. than B. when C. as D. while（答案为A）
（2）Scarcely had he opened the door when a gust of wind blew the candle out.他刚打开门，蜡烛就被一阵风吹灭了。
表示在将来某一时间以前完成的动作。
1、By the time John gets home, his aunt _____.
A. will have B. leaves C. will have left D. is leaving（答案：C）
2、I _____ writing the article by the time you get back.
A. shall finish B. must have finished C. have finished D. shall have finished（答案：D）
表示从过去某时一直延续到现在的一个动作，这个动作一般会继续延续下去，或是到说话时结束，但是强调到说话时为止一直在做的动作。
例：I _____ on the door for ten minutes now without an answer.
A. was knocking B. am knocking C. knocking D. have been knocking（答案：D）
