现在完成时:

1. 过去发生或完成的动作对现在造成了一定的影响和后果;

2. 结构:由助动词h**e/has +动词的过去分词构成;

肯定句。现在完成时的肯定句式是“h**e(has)+过去分词”。

注意:该句式中的h**e或has是助动词,has用于第三人称单数,其它人称一律用h**e。

疑问句。现在完成时的一般疑问句式是把助动词h**e或has提到主语之前。

回答:yes, …h**e(has).

no, …h**en’t(hasn’t).

否定句:现在完成时的否定句式是“h**en't(hasn't)+过去分词”。

3. 现在完成时的时间状语:already, just, yet, since, ever, never;

4. 与一般过去时的区别:一般过去时是强调动作在过去发生,而现在完成时是强调过去发生的动作对现在造成了影响和后果。

5.一般过去时的时间状语:yesterday, just now, …ago, last week, 2 years ago,in 1980等。

例:we planted (plant) some flowers in the garden last week.

与现在完成时连用的几个副词:already, just, ever, yet, never

肯定句: already, just

疑问句和否定句: ever, yet, never

yet 常置于句末。

already, never, ever just一般置于助动词h**e/has之后,过去分词之前.

例:用 already, just或never, yet完成句子。

1) i h**e been to many big cities, but i h**e never been to shanghai.

2) most of us h**e already finished our compositions.

1)for + 一段时间(用how long提问)

2)since + 句子/

具体时间。since 引导的短语或从句用how long提问。

since+过去一个时间点(具体的年、月、日、钟点等)。

tom has eaten nothing since yesterday.

since + 一段时间+ago

we h**e been friends since five months ago. 从5个月前起,我们就成了朋友。

since+从句,表示“自过去某个时间、某件事情以来”,从句时态:一般过去时。
