英语动词时态：【将来完成进行时】，这一语言点在最近的考试中也有所考查。将来完成进行时的典型句型结构为人称+ will/shall + have + been + doing再加其他时间状语成分，用来表示在将来某个时间点前一直持续的动作，首先让我们来看一个例题：

例：By the time you arrive this evening, ____ for two hours.

　A.I will study B.I will have been studied C.I had studied D.I will have been studying

　　【答案】D。本句的意思是：到今晚你来的时候，我就已经学习了两个小时了。将来完成进行时强调的是在某个时间点之前一直进行或持续的动作，在本题中，应该选D。

接下来，就趁着这个劲头来做几个选择题吧！

1. By Friday midday, they __________________ on it for seven days.

本句意为：到星期五中午，他们就在这个工程上干了7天了。

A.will have been working B.will work

C.have been studied D.will have been studied

2. Tom and Karen ___________________ by March 2017.

本句意为：汤姆和凯伦在2017年3月之前都在度假。

3. By this summer, __________________ here for five years.

检查一下看看，大家都做对了吗？
