亲爱的同学们，你们肯定跟室友卧谈吧？是不是也跟同伴这样说，十年后的今天我都已经成为了boss，开着BMW 了？你的卧谈不经意间与你的室友温习了有关英语的一个时态呢。Yes！那就是将来完成时。下面让我们一起来学习一下吧！
12.1将来完成时概述
1.定义
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，或是发生在某个将来时间，但对其后的另一个将来时间有影响的动作或状态。
将来完成时就如同把现在完成时平移到时间轴的将来时时段一样，其用法从与过去及现在有关，变成了与将来及将来的将来有关。
2.构成
将来完成时的基本构成形式如下：
(shall) will+have+ 动词的过去分词
例如：
We will have studied English for 10 years by the end of this year.
将来完成时经常与“before+将来时间”或“by+将来时间”连用，也可与before 或者by the time 或by the end of 引导的现在时的从句连用。

M： Go ahead and go for a walk.Don"t worry about this housework.By the time you get back I shall have finished it.（将来完成时表示在将来某时刻前已完成的动作，常与by，before 引导的表示将来的时间副词短语连用。）
W： But I really worry about my dishes.If you break one more plate， you will have broken twenty dishes.（将来完成时表示将来的经历或对其后的影响。）By the end of this month you will have broken all our dishes.You"re not to stop until all of them have been broken.（在时间状语从句中，可用现在完成时代替将来完成时，表示将来某一时刻以前已完成的动作。）
M： Darling， we can buy new ones.
W： No， unless all these old dishes have been broken.I shall not buy those new ones.
M： Darling， I will be more careful from now on.
注意：will 是情态助动词，有“大概”或“我想”的含义。例如：
You will have been wondering all the time how my invention works.
