将来完成时用来表示在将来某一时间以前已经完成或一直持续的动作.经常与before+将来时间或by+将来时间连用,也可与before或by the time引导的现在时的从句连用
如：I will have finished my task by 2 o'clock.
You will have reached Shanghai by this time tomorrow.
一般将来时 特殊用法一：某些表示位置移动的动词如arrive, come, go, leave, start等，用现在进行时形式表示将来。
I am leaving for London next month.. 特殊用法二：“祈使句 + and/or +
句子”，这种结构中and后面的句子谓语用一般将来时。 Work hard and you will succeed in time.
特殊用法三：“am (is, are) going to + 动词原形”，表示打算要做的事或可能要发生的事。 “am (is,
are) about to + 动词原形”表示按照预定计划或打算准备着手进行的动作。 “am (is, are) to +
动词原形”表示必须、必然或计划将要做的事。 Se is to get married next month. Lucy was
able to tell me the news when someone called her.
特殊用法四：在条件状语从句和时间状语从句中用一般现在时代替一般将来时（主将从现） 如：He will come as soon as he
receive my letter.(类似的词还有if.once) She is going to sleep when her
parents come back. 将来完成时 表在将来某时刻之前已完成的事情，时间状语非常明显。
特殊用法一：在时间、条件和让步状语从句中，表示在将来某个时间前先要做完的动作 将来完成时则由现在完成时表示。 I’ll return
the book to you as soon as I have finished reading it.. The children
will help their parents do some housework the moment they have arrived
back from school.
