Grammar B:The present perfect tense and the simple past tense
Work out the rule
We use (the present perfect tense/ the simple past tense) to talk about a past experience which has a connection to the present.
We use (the present perfect tense/ the simple past tense) to talk about a completed action in the past.
B 现在完成时与一般过去时
一般过去时和现在完成时所表示的动作都发生在过去,但要注
意以下区别:
现在完成时强调过去发生的动作对现在的影响或过去开始发生
一直持续到现在的动作。与特征词since, for, already, yet, ever, never, so far, up to now等连用。如:
— Would you like to see the film with me
你想和我一起去看这部电影吗?
— No. I’ve seen it twice.
不了,我已看了两遍了。(过去已看过,所以现在不想看了)
2 一般过去时强调动作在过去发生,与现在无关。与具体的表示过去时间的状语(如:yesterday, last night)连用。如:
I saw the film last night. 我昨晚看了那部电影。(仅是对过去事情的陈述)
区别 结构 常见连用词
现在完成时 (表示过去发生的动作对现在造成的影响或结果) have / has +过去分词 haven’t / hasn’t + 过去分词 Have / Has + 主语 + 过去分词 this day, these days,now,already,ever, yet, just, before, recently, up to now, in the last few years ...
一般过去时 (表示单纯的过去的事实或状态) 主语+动词过去式+其他 主语+didn‘t+ 动词原形 Did+主语+动词原形 yesterday, last X, just now, then, X ago, in 1994 ...
注意:在用when提问的句子中,一般都使用一般过去时。
