單元語法小專題(Grammar Focus),一、情態(tài)動詞的用法復(fù)習(xí) 情態(tài)動詞有can (could),may (might),must,have to,shall (should),will (would),dare (dared),need,ought to等。 情態(tài)動詞無人稱和數(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。,語法精講,1. 情態(tài)動詞的一般用法 (1)can,could ①表示能力(體力、知識、技能)。 此時可用be able to代替。can只有一般現(xiàn)在時和一般過去時;而be able to則有更多的時態(tài)。當(dāng)表示“經(jīng)過努力才得以做成功某事”時應(yīng)用be able to,不能用can。 ②表示請求和允許。 此時可與may互換。在疑問句中還可用could,might代替,不是過去式,只是語氣更委婉,不能用于肯定句和答語中。如: —Could I come to see you tomorrow?我明天可以來看你嗎? —Yes,you can./No,I'm afraid not.是的,可以。/不,恐怕不行。 ③表示客觀可能性(客觀原因形成的能力)。,(2)may,might ①表示請求和允許。 might比 may語氣更委婉,而不是過去式。否定回答時可用can't或mustn't,表示“不可以,禁止”。 用“May I…?”征詢對方許可時比較正式和客氣,而用“Can I…?”在口語中更常見。 ②用于祈使句,表示祝愿。如: May you succeed!愿你成功!,(3)must,have to ①表示必須、必要。 在回答由must引出的問句時,如果是否定的,不能用mustn't(禁止,不準(zhǔn)),而用needn't或don't have to(不必)。如: —Must we hand in our exercise books today?我們今天必須交練習(xí)本嗎? —Yes,you must.(No,you don't have to/you needn't.)是的,你們必須今天交。(不,你們不一定要今天交。) ②must是說話人的主觀看法,而have to則強(qiáng)調(diào)客觀需要。must只有一般現(xiàn)在時,而have to 有更多的時態(tài)形式。如: I had to work when I was your age.我像你這么大時,就必須工作了。,(4)dare,need ①dare作情態(tài)動詞用時,常用于疑問句、否定句和條件從句中,其過去式為dared。如: He daren't speak English before such a crowd,dare he?他不敢在人群前說英語,是嗎? ②need 作情態(tài)動詞用時,常用于疑問句、否定句。在肯定句中一般用must,have to,ought to,should代替。如: —Need I finish the work today?我需要今天完成這個工作嗎? —Yes,you must./No,you needn't.是的,必須今天完成。/不,不一定要今天完成。,③dare和 need作實義動詞用時,有人稱、時態(tài)和數(shù)的變化。在肯定句中,dare后面常接帶to的不定式。在疑問句和否定句中,dare后面可接帶to或不帶to的不定式。而need后面只能接帶to的不定式。如: He doesn't dare (to) answer.他不敢回答。 He needs to finish his homework today.他今天要完成家庭作業(yè)。,(5)shall,should ①shall 用于第一人稱,征求對方的意見。 What shall we do this evening?今天晚上我們做什么? ②shall 用于第二、三人稱,表示說話人給對方的命令、警告、允諾或威脅。如: You shall fail if you don't work hard.如果你不努力就會失敗。(警告),(6)will,would ①表示請求、建議等,would更委婉。 Will/Would you pass me the ball,please?你能把那個球遞給我嗎? ②表示意志、愿望和決心。如: I will never do that again.我再不會那樣做了。 ③would表示過去反復(fù)發(fā)生的動作或某種傾向。would表示過去的習(xí)慣時比used to正式,且沒有“現(xiàn)已無此習(xí)慣”的含義。如: During the vacation,he would visit me every other day.假期里,他每隔一天看我一次。,(7)should,ought to ①should,ought to表示“應(yīng)該”,ought to表示義務(wù)或責(zé)任,比should語氣重。如: I should help her because she is in trouble.我應(yīng)該幫她,因為她陷入麻煩了。 You ought to take care of the baby.你應(yīng)該照顧這個寶寶。 ②表示勸告、建議和命令時should,ought to可通用,但在疑問句中常用should。如: You should/ought to go to class right away.你應(yīng)該馬上去上課。 Should I open the window?我應(yīng)該打開門嗎?,2.情態(tài)動詞表推測 (1)can表示推測(驚訝、懷疑、不相信的態(tài)度),用于疑問句、否定句和感嘆句中。如: Can this be true?這可能是真的嗎? This can't be done by him.這不可能是他做的。 How can this be true?這怎么可能是真的? (2)may/might表示推測、可能性(不用于疑問句)。might不是過去式,它所表示的可能性比may小。如: Your mother may/might not know the truth.你媽媽可能不知道真相。,(3)must表示推測、可能性(只用于肯定的陳述句)。如: You're Tom's good friend,so you must know what he likes best.你是湯姆的好朋友,你一定知道他最喜歡什么。 (4)should,ought to (客觀推測),must(主觀推測)。如: He must be home by now.他現(xiàn)在一定回家了。(斷定他已到家) He ought to/should be home by now.他現(xiàn)在應(yīng)該到家了。(按理應(yīng)當(dāng),不太肯定),二、used to “闖三關(guān)” 1. 用法關(guān) used to后接動詞原形,表示過去經(jīng)常性或持續(xù)性的動作或狀態(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.我小的時候,冬天經(jīng)常很冷。 2. 句式關(guān) 其否定形式為“didn't use to do sth.”或“usedn't to do sth.”;一般疑問形式為“Used sb.to do sth.?”或“Did sb.use to do sth.?”;附加疑問句式為“use(d)n't sb.”或“didn't sb.”。,3. 辨異關(guān) be/get used to后面接名詞或動詞-ing形式時,表示“習(xí)慣于做某事”,其中to為介詞;be used to后面接動詞原形時,表示“被用來做某事”。其中to是不定式符號。如: I'm 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.這臺電腦被用來儲存信息。語法精練,Ⅰ. 用can,may,must,need,have to的適當(dāng)形式填空。 1.
