【知识梳理3】现在完成时中的时间状语：
★already通常用于肯定句中，意为“已经”，位于行为动词之前, be动词、助动词之后。

有时可放在疑问句句尾，表示惊讶。

例如：
We have already cleaned the classroom.
Have you finished it already？
★yet用于疑问句中表示“已经”；用于否定句中，表示“还(没)”。

例如：
—Has he found his watch yet？他还没找到他的表吗？
—No, not yet. 是, 还没有。

★ever意为“曾经”，常用于疑问句或否定句中，位于助动词和过去分词之间，表示从过去到目前为止的时间。

例如：
Have you ever been there？你曾经去过那里吗？
Nothing has ever happened here. 这里未曾发生过什么事。

★never意为“（曾经）从未、没有”, 是否定副词，在句中位于助动词和过去分词之间。

ever与否定词not连用相当于never。

例如：
I haven’t ever spoken to her. = I have never spoken to her. 我从未跟她讲过话。

★just意为“刚刚”, 用于现在完成时, 表示行为刚刚过去, 位于助动词与过去分词之间。

e.g. He has just come back from school.他刚从学校回来。

★for 和since的用法及区别。

for 与一段时间连用，since 与时间点连用。

注意：since 后接过去时的时间状语或过去时的句子。

e.g. I have been to Shanghai twice since 1970.
I haven’t seen her since she left Shanghai.
I saw Pingping six years ago. Since I have never seen her.
★recently，in recent years ,in the past few/five years ,so far ,up to now ……
★区别：have been to, have gone to, have been in
have been to,表示去过某个地方，不过现在已经回来了
have gone to表示去了，但还没有回来，也许是在去的途中
【知识梳理4】持续性动词 VS. 短暂性动词
★注意：表示短暂时间动作的词，如:come ，go ，die ，marry ，buy 等的完成时不能与for ，since 等表示一段时间的词连用。

用来持续的动作或状态或表过去重复的动作，如live ，study ，be ，wait 等，常和since （自从）或for （经历）引导的词语连用。

如：I have lived here for more than thirty years.我已在此住了30多年。

【例题17】The old man________ last year. He________for a year. (die) 【例题18】This factory opened twenty years ago. (同义句转换)
