1、 河北省唐山市开滦第二中学高中英语 Unit5 Meeting your ancestors 第5课时导学案 新人教版选修8【学习目标】现在完成进行时【重点难点】现在完成进行时和现在完成时区别 【学习内容】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

2、/ 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 ha

3、s 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

4、for many years. 我在这儿住了多年了。(4）现在完成进行时往往表示动作在重复，现在完成时则常常不带重复性。如： Have you been meeting her lately？（a） Have you met her lately？（b） （a）句有“经常相会”之意，（b）句则没有。（b）句如与often，every day等时间状语连用，当然也表示动作在重复。 （5）现在完成进行时比较生动，有时含有明显的感情色彩，而现在完成时往往只说明一个事实，一种影响或结果，平铺直叙，没有什么感情色彩可言。如： Whos been eating my apples？（a） Whos eat

5、en my apples？（b） （a）句有强烈的感情色彩，表示愤怒不满，（b）句只是希望回答的一个问题。又，（a）句兼有进行时态，所以有“苹果未被全部吃光”的意思，（b）句是完成时态，说明“苹果一个不剩了”。【课后作业与练习】 完成句子1.
