3、d after by her sister.這嬰兒由她的姐姐照顧。used to do sth.語法精講1用法used to后接動(dòng)詞原形，表示過去經(jīng)常性或持續(xù)性的動(dòng)作或狀態(tài)，意為“過去常?！?。如：I used to get up very early.我過去常常很早起床。When I was young，it used to be very cold in winter.在我小的時(shí)候，冬天經(jīng)常很冷。2句式其否定形式為didnt use to do sth.或usednt to do sth.；一般疑問形式為Used sb.to do sth.？或Did sb.use to do sth.？；附

4、加疑問句式為usednt sb.或didnt sb.。3辨異be/get used to后面接名詞或動(dòng)詞ing形式時(shí)，表示“習(xí)慣于(做)某事”，其中to為介詞；be used to后面接動(dòng)詞原形時(shí)，表示“被用來做某事”。其中to是不定式符號(hào)。如：Im used to walking to school now.我現(xiàn)在習(xí)慣步行去學(xué)校。The computer is used to store information.這臺(tái)電腦被用來儲(chǔ)存信息。情態(tài)動(dòng)詞有一定的詞義，但不能獨(dú)立作謂語，須與動(dòng)詞原形一起構(gòu)成謂語，表示說話人的情緒、態(tài)度和語氣。情態(tài)動(dòng)詞沒有人稱和數(shù)的變化。can(could)表能力，cou

5、ld表過去的能力。can與be able to的意義基本相同。但can只有一般現(xiàn)在時(shí)和一般過去時(shí)，而be able to能用于各種時(shí)態(tài)。表可能性。表許可。口語中可代替may。cant表有把握的否定判斷，意為“不可能”。could在口語中，常代替can來向?qū)Ψ奖容^委婉客氣地提出請(qǐng)求或表示看法。此時(shí)could不表示過去時(shí)。may(might)用來征求對(duì)方意見，意為“可以”。口語性較強(qiáng)。might可以指過去的時(shí)間；也可指現(xiàn)在的時(shí)間，語氣更委婉。表猜測(cè)和對(duì)可能性的判斷，意為“可能；也許”。might可以指過去的時(shí)間；也可指現(xiàn)在的時(shí)間，但語氣更加不肯定。must表說話人的主觀意愿，意為“必須，應(yīng)該”。無

6、時(shí)態(tài)變化。其否定答語常用neednt或dont have to，意為“不必”。注：have to意為“不得不；必須”，主要強(qiáng)調(diào)受到外界客觀因素的迫使。它可用于多種時(shí)態(tài)，且有人稱和數(shù)的變化。must本身的否定形式mustnt意為“不許；一定不要”，表示禁止和告誡。表示對(duì)事物的推測(cè)，意為“想必；一定”，只用于肯定句。且比may的語氣要肯定得多。would作情態(tài)動(dòng)詞時(shí)，無人稱限制，表意愿，常與like，love連用。should表義務(wù)，意為“應(yīng)該”(某件事宜于做)，用于各種人稱。表推測(cè)，意為“想必一定；照說應(yīng)該、估計(jì)”等。一、根據(jù)句意，用括號(hào)內(nèi)所給單詞的適當(dāng)形式填空。1Some students a
