外研版通过本课的学习，学生能够：①总结归纳含有already、just和yet的现在完成时的用法。②能够理解关于太空飞行的听力和阅读材料。LearningGoalsLet’sfirstenjoyavideoandthentellwhichtenseyoucanhearmostoften.Todaywe’regoingtolearnmoreaboutthepresentperfect.WarmingUpLanguagepracticeCanyoutranslatethefollowingsentencesintoEnglish?1.我刚做了一架宇宙飞船模型。2.宇航员已经到过月球了。3.它已经到了吗？4.我们没有在其他任何星球上发现生命。I’vejustmadeamodelspaceship.Astronautshavealreadybeentothemoon.Hasitarrivedyet?Wehavenotfoundlifeonanyotherplanetsyet.I’vejustmadeamodelspaceship.Astronautshavealreadybeentothemoon.Hasitarrivedyet?Wehavenotfoundlifeonanyotherplanetsyet.Lookatthesethreewords.Howmuchdoyouknowaboutthem?（1）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。同时，可分用just,already或yet加以强调或说明。Ihavejustheardthenews.我刚听到消息。astronautshavealreadybeentothemoon.宇航员已经去过月球了。Hehasjuststartedtoexploreotherplanets.我们才刚刚开始探索其他行星。可以看出，just用来表示“刚刚”，already用来表示“已经”，两者都用于肯定句中，一般是置于have/has之后。在否定句中则可用yet,表示“还未”，有“以后可以会”的含义。（2）另外，在使用现在完成时的时候，要注意与一般过去时的区别。现在完成时在表达经历时只表示该事件是在现在之前的某一个时间里发生的，重点在于已完成动作对现在的影响。而一般过去时则表示在过去某一具体时间发生的事情。IhavejustbeentoLondon.Iwenttherelastmonth.我刚去过伦敦，上个月去的。Ihavealreadyfinishedmyhomework.Ifinisheditanhourago.我已经完成家庭作业了，一小时前完成的。（3）在没有明确的过去时间状语时，如何判断该用现在完成时还是该用过去时呢？判断的标准是看该行为是否对现在有影响，也就是说该句强调的是什么。试看以下对话：A:Wherehaveyouputmybook?Ican’tfindit.你把我的书放哪儿去了？我找不到。B:Iputitonyourdeskyesterday.我昨天放你桌子上了。该对话中，当A问对方把自己的书放在何处时，A感兴趣的是现在的状态，因此用现在完成时。但是B回答时只是说明当时放的位置，所以用一般过去时。SpaceshiponMars!Astronautshave(1)________beentothemoonbuttheyhavenotbeentoanyotherplanets.However,aspaceshiphas(2)________arrivedonMarsandithas(3)________sentbackphotosoftheredplanet.IstherelifeonMars?Wedonotknow(4)________.1Completethenewswithalready,justandyet.alreadyjustalreadyyet·ThespaceshiphasgonetoMars.
