(十一) 将来完成时
表示在将来某一时间之前完成的动作，并往往对将来某一时间产生影响。
将来完成时的谓语形式: will (shall) have+ 过去分词

Before long, he will have forgotten all about the matter.(before long 不久)
How many words will you have learnt by the end of the term?

主要复习了动词的十一个时态。重点记忆主句将来时，时间状语从句、条件状语从句用一般现在时。现在完成时中for和since的区别，for接一段连续的时间状语，since接过去时句子或过去的时间状语。有for或since的现在完成时句子中，动词只可以是表延续的动词。现在完成进行时可以接所有的动词。
进行时态的运用往往根据上下文来决定。
Be quiet, everybody. The students of Class One are having a listening test.
When I was cooking these potatoes, I forgot to put any salt in it.
在运用完成时态时，应特别注意表示瞬息间动作的动词不能与for 引导的一段时间状语连用。
瞬息间动词往往须换成"be+副词/介词结构"的形式，或选用句式"It is / has been + 时间状语 + since ……"来表态。
1."Have the visitors arrived?"
"Yes, they have been here for an hour."
2.By the time we got to the cinema, the film _______ for half an hour.
A. has begun B. had begun C. has been on D. had been on
(begun不表延续，答案 D)
3.It has been less than three months since she joined the army. / she has been in the army for less than three months.(不能说 She has joined the army for less than three months.)
过去完成时也是一个相对的时态，是在过去的某个时间或动作之前发生的事。
1.He has already gone home. But before he left, he _________ all the mistakes in his translation.
A. had corrected B. has corrected C. would correct D. will correct
(答案 A)
2.He showed me the pictures he had taken of the animals the day before.
过去将来时也是一个相对的时态，是在过去的某个时间看将要发生的事。
