  【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。

5.高二年级必修五英语知识点总结

  表示时间的介词

  (1) in表示“在某一时间段”或“在某一时候”,如用在月、季、年份、时代、世纪等时间名词的前面,或用来泛指一天的某一段时间。in也可以指“在……之后”,表示从说话起的若干时间内。

  如: in July/summer/20xx/ancient times

  The bus will be here in ten minutes.

  (2) on表示“在特定的某一天”,也可用于带有修饰语的.一天的某个时间段之前。如:on Saturday, on Saturday morning, on the morning of August 1st

  (3) at表示“在某一时间点”,或用来表示不确定的时间和短期的假日、时节等。

  如:at six o'clock, at Easter

  (4) over, through (out)两者均指“经过的全部时间”。

  如:Stay over the Christmas.

  (5) for与since:for表示动作或状态延续的全部时间长度,为“长达……”之意;since用于指从过去特定的某个时刻到说话时为止的一段时间;含有since时间短语的句子要用完成时,但含有for时间短语的句子不一定要用完成时。
