Unit 3Language in use
Present perfect (2)
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. Astrnauts have already been t the mn. 宇航员已经去过月球了。3. We have just started t explre ther planets. 我们才刚刚开始探索其他行星。
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
现在完成时与 just 和 already
1. The scientists have nt heard frm it yet. 科学家还没有收到它发出的信息。2. Man has nt discvered any life in space yet. 人类尚未在太空中发现任何生命。3. Have the children cme hme yet? 孩子们已经回家了吗？
否定句:表示“还未（以后可能会）”
现在完成时：have/has + been/V-ed 一般过去时：主语 + 动词过去式
① We have lived here fr three years. 我们已经在这里住了3年了。② They lived here in 2011. 他们2011年住在这里。
现在完成时与一般过去时
① I have just been t Lndn. I went there last mnth. 我刚去过伦敦，上个月去的。② I have already finished my hmewrk. I finished it an hur ag. 我已经完成家庭作业了，一小时前完成的。
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。
现在完成时是一个与过去和现在都有关系的时态，因此，具有这样时间特点的状语都可以与现在完成时连用。一般过去时常与表过去的具体的时间状语连用。
① His father has been a teacher since 1968.② - Have yu ever been t Lndn? - N, I have never been there.③ Did yu watch that film last week? ④ She came back yesterday.
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 yu put my bk? I can't find it. B: I put it n yur 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: Wuld yu like t g and see the film with me tnight?B: Srry, 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”。
