【现在完成进行时】
1. 现在完成进行时的定义
现在完成进行时表示某动作从过去某个时间开始,一直延续到现在,并且还有可能持续下去。如:
We have been waiting for him for two hours. 我们等他等了两个小时。
2. 现在完成进行时的结构
现在完成进行时由“have /has been + 现在分词”构成。
3. 现在完成进行时的应用
现在完成进行时所用的时间状语:this month / week / year, these days, recently / lately, in the past few + 时间段, since +时间点, for + 时间段。如:
They have been building the bridge for two month. 两个月来他们一直在修桥。
They have been planting trees this month. 这个月来他们一直在植树。
4. 现在完成进行时与现在完成时的区别
(1) 现在完成时强调动作的完成,而现在完成进行时强调动作的延续,因此,表示动作的完成,只能用现在完成时,而不能用现在完成进行时。如:
He has changed his idea. 他改变了想法。
(2) 在表示动作的延续时,虽然既可用现在完成时,也可用现在完成进行时,但现在完成进行时强调动作的进行。因此在需要明确表示动作还要持续下去时,应用现在完成进行时。如:
We have been studying here for two years. 我们在这儿已经学习了两年了。
(3) 有些延续性动词(如 keep, learn, live, stay, study, work等),用于现在完成时或现在完成进行时的区别不大。如:
I have lived here for many years.=I have been living here for many years. 我在这儿住了多年了。
