【正文】 t you/we...?”的簡(jiǎn)略形式。t we stay here another day?(4).用“Would you like...?”來(lái)提出建議,意思是“你想要……嗎?”Would you like后可接名詞或不定式。s go for a swim,shall we? What about/How about going swimming? Why not go for a swim? Would you like to go for a swim? What do you think of going for a swim?8. should的用法:(1).should 意為“應(yīng)該” ,可表示勸告、建議、義務(wù)、責(zé)任等。(2)Should have done 表示對(duì)過(guò)去動(dòng)作的責(zé)備、批評(píng)。(事實(shí)上你沒(méi)有完成。如:I will help you if I’m free this ,我就會(huì)幫你。 由于“一般將來(lái)時(shí)”的結(jié)構(gòu)可以用“will+動(dòng)詞原形”來(lái)表示,所以there be句型的一般將來(lái)時(shí)的形式就是there will be。He is seriously ill. He is going to die. He will be twenty years old. ③. be going to 含有“計(jì)劃,準(zhǔn)備”的意思,而 will 則沒(méi)有這個(gè)意思,如: She is going to lend us her book. He will be here in half an hour. ④.在有條件從句的主句中,一般不用 be going to, 而多用will, 如: If any beasts es at you, I39。如:We had better go now. 我們最好現(xiàn)在就走??键c(diǎn)二:含有情態(tài)動(dòng)詞的疑問(wèn)句的回 may 引出的問(wèn)句,可以有下列回答方式:肯定回答:Yes, you may. Yes, of course. Yes, certainly. Sure . 否定回答:No, you mustn’t. No, you can’t.,回答方式為:Yes, …must. No,… needn’t/ don’t have to.,表示委婉的語(yǔ)氣,此時(shí) could 沒(méi)有過(guò)去式的意思。(注意回答)4. shall引出的疑問(wèn)句用于第一人稱(chēng), 表示征求對(duì)方意見(jiàn)或客氣的請(qǐng)求。答案:B考點(diǎn)三: 不同情態(tài)動(dòng)詞的否定意義也不同:1.(1).can’t可譯為“不會(huì)”, 如:I can’t play basketball. 我不會(huì)打籃球。(3)can’t 還可用來(lái)回答“ May I …? ” 這樣的問(wèn)句。(4)can’t 還可用于固定習(xí)語(yǔ)中。The children can’t wait to open the box. 孩子們迫不及待地想打開(kāi)盒子。3.(1)mustn’t 表示不許,不可。You mustn’t talk in class. 你們不可以在課上說(shuō)話(huà)。 如:—May I stand here? 我可以站在這里嗎?—No, you mustn’t (can’t). 不,不行。如:You needn’t meet him unless you’d like ,除非你愿意。 如: You needn’t have bought it. 你沒(méi)必要買(mǎi)它(但你卻買(mǎi)了)。 如:You shouldn’t feel so unhappy over such little things. 對(duì)于這種小事,你不應(yīng)該感到這么不高興。做題時(shí)要兼顧情態(tài)動(dòng)詞和被動(dòng)語(yǔ)態(tài)這兩個(gè)方面。She shouldn’t speak to her mother in that 。Many of the stars can not be seen because they are far away from ,因?yàn)樗鼈冸x 我們太遠(yuǎn)了。can表示推測(cè)時(shí)一般用于否定句或疑問(wèn)句。 如:He must be in his office Li must be working now, for the lights in his office are still on.might 表示推測(cè)時(shí)不一定是may的過(guò)去時(shí),只是表示其可能性較小。如:—Could it be an animal?—It could not be, because it is not moving.Should表示推測(cè)的可能性比較大,僅比must的可能性 小一點(diǎn)?!癿ust +have done/been”表示“過(guò)去一定發(fā)生過(guò)某事或存在過(guò)某種狀態(tài)”,不用于“musn’t+have”形式。以上結(jié)構(gòu)常帶有說(shuō)話(huà)者的責(zé)備的感情色彩。如:There was plenty of time. She needn't have hurried .“can’t /couldn’t+have done /been”表示“過(guò)去不可能發(fā)生了某事或存在過(guò)某種狀態(tài)”?!癱ould sb. have done /been?”是它的問(wèn)句形式。 如:He may have finished reading the book. She might have given you some help,however bus she was.【情態(tài)動(dòng)詞易混點(diǎn)歸納】易混點(diǎn)一: can和be able to:兩者表示能力時(shí)用法相同,但can只有原形“can”和過(guò)去式“could”兩種形式,在其他時(shí)態(tài)中 要用be able to 來(lái)表示。如:Jim can’t speak 。We’ll be able to see him next 。I’m sure you’ll be able to finish it 。易混點(diǎn)二:can和may1. can 和 may 均可用來(lái)征求意見(jiàn)或許可,意為“可以”, 一般可互換使用。 如:She may be in the classroom . 她可能在教室里。易混點(diǎn)三: may be 和maybe   用法區(qū)別 常用位置may be may為情態(tài)動(dòng)詞, be為動(dòng)詞原形 句中,作謂語(yǔ)maybe 副詞,大概、也許,相當(dāng)于perhaps 句首,作狀語(yǔ)例如:He may be wrong , but I’m not sure. 也許他錯(cuò)了,但我也不確定。如:I can’t speak English . 我不會(huì)說(shuō)英語(yǔ)。如:We can’t do it now because it’s too ,我們現(xiàn)在干不了?!安豢赡堋?,如:The man can’t be our teacher because he is much younger than our teacher.. 那個(gè)人不可能是咱們老師,他年輕得多。 如:You mustn’t play football in the street.

It’s nothing serious. A. can’t B. mustn’t C. needn’t D. won’t【解析】 由題干 It’s nothing serious 可推斷,第一句意為“你不必為我擔(dān)心”, 故選C。答案:C—Excuse me. Is this the right way to the Summer Please? —Sorry, I’m not sure . But it _______ be.A. might ’t ’t 【解析】考查情態(tài)動(dòng)詞might 表推測(cè)的用法。答案:AThe man in the office___be Mr. Black, because he went home just now.’t not ’t ’t【解析】 由下文 he went
