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！
