现在完成时和现在完成进行时的区别
行时关注动作本身,特别是解释动作可见的结果时。 He’s run three miles. (the result: He’s covered the distance of three miles.) He’s been running for an hour. (the activity and its consequences: this is what he’s been doing for the last hour and why he is exhausted now.) 3、现在完成进行时表示重复的动作时,不能同表示具体数字的词并用。 I’ve posted a dozen postcards, but received none. I’ve read this book several times. I’ve been posting postcards since early December. 4、现在完成进行时带有较为强烈的感情色彩。 You have been disturbing me. 5、许多状态动词不能用完成进现在完成时 1、表示过去开始并持续到现在的动作。(动词必须是持续动词) China has changed a great deal in the past 20 years. 2、强调过去动作对现在行时。 I’ve known that for a long time. The strike has lasted six months. 6、有少数动词用两种时态都可以,但若强调时间长度时用完成进行时较好。 They have been working this term. They have worked very well this term.
