外研版通過本課的學(xué)習(xí)，學(xué)生能夠：①總結(jié)歸納含有already、just和yet的現(xiàn)在完成時的用法。②能夠理解關(guān)于太空飛行的聽力和閱讀材料。LearningGoalsLet’sfirstenjoyavideoandthentellwhichtenseyoucanhearmostoften.Todaywe’regoingtolearnmoreaboutthepresentperfect.WarmingUpLanguagepracticeCanyoutranslatethefollowingsentencesintoEnglish?1.我剛做了一架宇宙飛船模型。2.宇航員已經(jīng)到過月球了。3.它已經(jīng)到了嗎？4.我們沒有在其他任何星球上發(fā)現(xiàn)生命。I’vejustmadeamodelspaceship.Astronautshavealreadybeentothemoon.Hasitarrivedyet?Wehavenotfoundlifeonanyotherplanetsyet.I’vejustmadeamodelspaceship.Astronautshavealreadybeentothemoon.Hasitarrivedyet?Wehavenotfoundlifeonanyotherplanetsyet.Lookatthesethreewords.Howmuchdoyouknowaboutthem?（1）當(dāng)表示動作已經(jīng)完成，并對現(xiàn)在有一定影響時，我們一般用現(xiàn)在完成時。同時，可分用just,already或yet加以強調(diào)或說明。Ihavejustheardthenews.我剛聽到消息。astronautshavealreadybeentothemoon.宇航員已經(jīng)去過月球了。Hehasjuststartedtoexploreotherplanets.我們才剛剛開始探索其他行星?？梢钥闯觯琷ust用來表示“剛剛”，already用來表示“已經(jīng)”，兩者都用于肯定句中，一般是置于have/has之后。在否定句中則可用yet,表示“還未”，有“以后可以會”的含義。（2）另外，在使用現(xiàn)在完成時的時候，要注意與一般過去時的區(qū)別?，F(xiàn)在完成時在表達(dá)經(jīng)歷時只表示該事件是在現(xiàn)在之前的某一個時間里發(fā)生的，重點在于已完成動作對現(xiàn)在的影響。而一般過去時則表示在過去某一具體時間發(fā)生的事情。IhavejustbeentoLondon.Iwenttherelastmonth.我剛?cè)ミ^倫敦，上個月去的。Ihavealreadyfinishedmyhomework.Ifinisheditanhourago.我已經(jīng)完成家庭作業(yè)了，一小時前完成的。（3）在沒有明確的過去時間狀語時，如何判斷該用現(xiàn)在完成時還是該用過去時呢？判斷的標(biāo)準(zhǔn)是看該行為是否對現(xiàn)在有影響，也就是說該句強調(diào)的是什么。試看以下對話：A:Wherehaveyouputmybook?Ican’tfindit.你把我的書放哪兒去了？我找不到。B:Iputitonyourdeskyesterday.我昨天放你桌子上了。該對話中，當(dāng)A問對方把自己的書放在何處時，A感興趣的是現(xiàn)在的狀態(tài)，因此用現(xiàn)在完成時。但是B回答時只是說明當(dāng)時放的位置，所以用一般過去時。SpaceshiponMars!Astronautshave(1)________beentothemoonbuttheyhavenotbeentoanyotherplanets.However,aspaceshiphas(2)________arrivedonMarsandithas(3)________sentbackphotosoftheredplanet.IstherelifeonMars?Wedonotknow(4)________.1Completethenewswithalready,justandyet.alreadyjustalreadyyet·ThespaceshiphasgonetoMars.
