用法
just，already和yet在现在完成时中的用法；
现在完成时与一般过去时的区别。
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。
Present perfect with already and just
两者都用于肯定句中，一般置于have/has之后, V-ed 之前
just “刚刚”
already “已经”
1. The scientists have not heard from it yet.
科学家还没有收到它发出的信息。
2. Man has not discovered any life in space yet.
人类尚未在太空中发现任何生命。
3. Have the children come home yet
孩子们已经回家了吗？
置于句末
Present perfect with yet
yet
用于
否定句: “还未（以后可能会）”
疑问句:“已经”
一、构成不同
一般过去时：主语 + 动词过去式
现在完成时：have/has + been/V-ed
1) They lived here in 2011.
他们2011年住在这里。
2) We have lived here for three years.
我们已经在这里住了3年了。
1. I have just been to London. I went there last month.
我刚去过伦敦，上个月去的。
2. 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。
二、用法不同
三、时间状语不同
1. Did you watch that film last week
你上周看那部电影了吗？
2. She came back yesterday.
她是昨天回来的。
3. His father has been a teacher since 1968.
他父亲从1968年以来一直当老师。
4. — Have you ever been to London
— No, I have never been there.
— 你曾经去过伦敦吗？
— 没有，以前从没去过。
现在完成时常与表不确切的时间副词连用。
一般过去时常与表过去的具体的时间状语连用；
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。
A: Would you like to go and see the film with me tonight
B: Sorry, I have seen it already.
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”。
Astronauts have (1)_______ been to the moon but they have not been to any other planets. However, a spaceship has (2) _____ arrived on Mars and it has (3) ______ sent back photos of the red planet. Is there life on Mars We do not know (4)______.
