Grammar
现在完成时（2）
当表示动作已经完成并对现在有一定影响时，我们一般用现在完成时来表达。此时，可以分别用just，already或yet加以强调或说明。 如：
Present perfect with already, just and yet
Present perfect with already, just and yet
1. I have just heard the news.
我刚听到消息。
2. Astronauts have already been to the moon.
宇航员已经去过月球了。
3. We have just started to explore other planets.
我们才刚刚开始探索其他行星。
4. The scientists have not heard from it yet.
科学家还没有收到它发出的信息。
5. Man has not discovered any life in space yet.
人类尚未在太空中发现任何生命。
6. Have the children come home yet
孩子们已经回家了吗？
just “刚刚” 两者都用于肯定句中
already “已经” 一般置于have/has
之后, V-ed 之前
yet 用于 否定句: “还未”、“以后可能会”
疑问句: “已经”
置于句末
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，
重点在于强调已完成动作对
现在的影响
一般过去时表示在过去某一具体时
间发生的事情
现在完成时与一般过去时
I have just been to London.
I went there last month.
我刚去过伦敦，上个月去的。
I have already finished my homework.
I finished it an hour ago.
我已经完成家庭作业了，一小时前完成的。
试比较
当 A 问对方把自己的书放在何处时，他强调的是现在找不到了，故用现在完成时。但B的回答只是说明当时放的位置，故用一般过去时。
A: Where have you put my book I can’t find it.
B: I put it on your desk yesterday.
当没有明确的过去时间状语时，判断该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，即该句所强调的是什么。如：
A: Would you like to go and see the film with me tonight
你今晚想和我去看电影吗？
B: Sorry, I have seen it already.
不好意思，我已经看过那部电影了。
此时的现在完成时表示对结果的强调：“电影看过了，所以不想再看了”。
