名師提醒情態(tài)動詞(may/might，can/could，must等)無人稱和數(shù)的變化；不能單獨(dú)使用，必須與其后的動詞原形構(gòu)成謂語。名師提醒can和beableto都表示能力，意思上沒多大區(qū)別。但can只有現(xiàn)在和過去時，而beableto則有更多的形式。但當(dāng)成功地完成某一具體動作時，通常不用could而用was/wereableto來表示。這時was/wereableto相當(dāng)于managedto，表示經(jīng)過一番努力，終于能夠完成某事。HermothercanspeakFrench.他媽媽會講法語。Thewoundedmanwasstillabletogettothevillageandwassavedbythevillagersintheend.那個受傷的人仍然能夠到達(dá)那個村莊，最后被村民們救了。名師提醒can的特殊用法。canbut只好；can’tbut不得不；can’t...too再……也不為過，越……越好Icanbutwait.我只好等了。Ican’tbutwait.我不得不等。Youcan’tbetoopatienttothecustomers.你對顧客再耐心也不過分。名師提醒表示祝愿(不用might)Mayyousucceed！祝你成功！即學(xué)即練補(bǔ)全句子1.___________________________what’shappeningoverthere?

你能告訴我那邊發(fā)生了什么事嗎？2.________________________withthemanager，sir?

先生，我可以和經(jīng)理談?wù)剢幔?/p>

Could/CanyoutellmeMayIhaveaword3.Man_______________oranyotherstarintheuniversenow，butwe_______________yearsago.

人類現(xiàn)在可以到達(dá)月球或宇宙中的任何其他恒星，但多年前我們無法到達(dá)那里。4.Johnny，you____________________________，you_____________________.

約翰尼，你不能玩刀子，你會傷著自己的。5.You__________________________thisproblem，thoughitwasalittledifficult.

你可能已經(jīng)解決了這個問題，雖然它有點(diǎn)困難。
