I’ve just made a mdel spaceship. Has it arrived yet? Astrnauts have already been t the mn. We have nt fund life n any ther planets yet.
现在完成时：某人曾经做过某事 某人已经做了某事
★ just, already, yet 可用于现在完成时,加以强调或说明。★ just用来表示“刚刚”，already用来表示“已经”，两者都用于肯定句中，一般置于have /has之后，already 也可放在句末。在否定句及疑问句中用yet, 表示“还未”。
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对 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 t Lndn. I went there last mnth.我刚去过伦敦，是上个月去的。I have already finished my hmewrk. I finished it an hur ag.我已经写完作业了，一个小时之前完成的。
A: Where have yu put my bk? I can’t find it.B: I put it n yur 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。
有明确过去时间状语时，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。
