用法
表示一个持续到现在的动作
现在完成进行时表示“动作从过去某一时间开始一直延续到现在,并且有可能继续下去”。
用于现在完成进行时的动词,一般为延续性动词,并常和all the time,this month/week,all night,all morning等状语以及since和for引导的时间状语连用。
I ( learn) English since I was 8 years old and I still love it.
2. I ( write) this novel since last year.
表示动作刚刚结束
表示不久前刚刚结束的动作。这种意义通常根据上下文来判断。
1. Her eyes are red. It's obvious(显然的) that she ( cry) for a long time.
2. — I am sorry I have kept you waiting so long.
— It is all right. I ( read) the newspapers.
表示动作重复发生
现在完成进行时可以用来叙述从过去某时持续到现在断断续续重复的动作,并不是一直不停的进行。这时,谓语动词可以是非延续性动词。常与表示“最近”意义的副词lately、recently等连用。
1. We ( practice) Kung Fu recently.
2. I ( visit) some cities of China this month.
表示某种感彩
现在完成进行时有时带有浓厚的感彩,表示愿望或感慨或强烈的表扬或厌恶的情绪。
I have been wanting to see you for a long time.
Recently Mary has been doing sports regularly.
最近玛丽一直定期做运动。(有表扬意味)
常用的时间状语
我们使用现在完成进行时来谈论从过去开始并且现在仍在继续的动作,或者刚刚完成但仍以某种方式与现在联系在一起的动作。该时态多用于延续性动词,如live,learn,lie,stay,sit,wait,stand,rest,study等,并常和all this time,this week,this month,all night,all the morning,recently 等状语以及由since和for构成的时间状语(从句)连用,与since和for连用时,常表示动作会继续下去。
现在完成进行时和现在完成时的区别
1.Translate:
① I've been designing cars.
② I've designed five or six different cars.
现在完成时常表示过去发生的动作对现在的影响,强调动作 ;而现在完成进行时强调动作仍然
2.Translate:
① Have you been meeting him recently
② Have you met him recently
现在完成进行时往往表示动作 ,而现在完成时不表示动作 。
Translate:
① I have waited for you for two hours.
② I have been waiting for you for two hours.
现在完成进行时比较生动,有时含有明显的 (喜悦、愤怒、不满、厌恶等),而现在完成时往往只说明 。
四.注意状态动词、知觉动词和情感动词see/feel/know/love等,某些不具延续性含义的动词,如come, go, marry, die, finish,leave等,不可用于现在完成进行时,但可用于现在完成时。
I have known her for a long time.
(该句中的状态动词know是一个非延续的动词,所不能用现在完成进行时,只能用现在完成时。)
