Grammar
现在完成时（2）
现在完成时如何使用呢？
当我们要表达“某人曾经做过某事”，“某人已经做了某事”等意思时，英语要用“现在完成时”来表达。
现在完成时的结构：
has/have+done(动词过去分词)
肯定句    否定句    疑问句
I/We/You/They have done...   I/We/You/They have not(haven't)done..Have you/they done..?
He/She has done...   He/She has not(hasn't)done... Has he/she done...?
表达“刚刚做完某事”。“已经做完某事”时，使用现在完成时。如：
1.I have just heard the news. 我刚刚听到消息。
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。
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.科学家还没收到他发出的信息。
Man has discovered any life in space yet.人类尚未在太空中发现生命。
常与现在完成时连用的副词：
already，just，ever，yet，never
肯定句：already，just
疑问句和否定句：never，yet，never，yet常置于句末。
already，just，ever，never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,never,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事件里发生的，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个具体实践发生的事情
I have just been to London.I went there last month.
我刚刚去过伦敦，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。
