“某人已经做了某事”等意思时, 英语要用“现在完成时”来表达。现在完成时(2)Grammar现在完成时的结构：
has/have + done (动词过去分词)表达“刚刚做完某事”、“已经做完某事”时，使用现在完成时。如:
I have just heard the news.
我刚听到消息。
Astronauts have already been to the moon.
宇航员已经去过月球了。
We have just started to explore other planets.
我们才刚刚开始探索其他行星。just “刚刚”，already “已经”，两者都用于肯定句中，一般置于have/has之后。
否定句中则用yet, 表示“还（未）”。如：
The scientists have not heard from it yet.
科学家还没有收到它发出的信息。
Man has not discovered any life in space yet.
人类尚未在太空中发现生命。already, just, ever, yet, never already, just ever, yet, never常与现在完成时连用的副词：
肯定句:
疑问句和否定句:
yet 常置于句末。
already, never, ever, just 一般置于助动词have/has之后，过去分词之前。A: Have you… ?
B: Yes, …/ No, …
(using already, just, ever, yet, never)现在完成时与一般过去时现在完成时表示该事件是在现在之前
的某一个时间里发生的，
重点在于强调这一动作与
现在的影响
一般过去时只表示过去的某一具体时
间发生的事情I have just been to London. I went there last month.
我刚去过伦敦，是上个月去的。
I have already finished my homework. I finished it an hour ago.
我已经写完作业了，一个小时之前完成的。A: Where have you put my book? I can’t find it.
B: I put it on your desk yesterday.
当 A 问对方把自己的书放在何处时，他在意的是书目前在哪儿，故用现在完成时。
B的回答着重的是当时的动作，故用一般过去时。无明确过去时间状语时，判断使用现在完成时还是一般过去时的标准是：
看该行为是否对现在有影响，即该句强调或在意什么，着重点就在那里。A: Would you like to go and see the film with me tonight?
B: Sorry, I ________ it already. (see)have seen注: word 文档
