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：Presentperfectwithalready,justandyet1.Ihave

just

heardthenews.我刚听到消息。2.Astronautshavealready

beentothemoon.宇航员已经去过月球了。3.Wehavejuststartedtoexploreotherplanets.我们才刚刚开始探索其他行星。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4.Thescientistshavenotheardfromit

yet.科学家还没有收到它发出的信息。5.Manhasnotdiscoveredanylifeinspaceyet.人类尚未在太空中发现任何生命。6.Have

thechildrencomehomeyet?孩子们已经回家了吗？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IhavejustbeentoLondon.Iwent

therelastmonth.我刚去过伦敦，上个月去的。Ihavealreadyfinished

myhomework.Ifinisheditanhourago.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:Wherehaveyouputmybook?Ican’tfindit.B:Iputitonyourdeskyesterday.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:Wouldyouliketogoandseethefilmwithmetonight?

你今晚想和我去看电影吗？B:Sorry,Ihaveseenitalready.

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”。Astronautshave(1)_______beentothemoonbuttheyhavenotbeentoanyotherplanets.However,aspaceshiphas(2)_____arrivedonMarsandithas(3)______sentbackphotosoftheredplanet.IstherelifeonMars?Wedonotknow(4)______.alreadyjustalreadyyetP21Completethenewswithalready,just
