He had done his best.（否定意味）He need have gone and sent that letter in person.（實(shí)際上沒(méi)有做）四、NEED與推測(cè)NEEDN’T表示“不一定”。（本條可參照must/can的用法。）1)NEEDN’T+BEIt needn’t be hot in Florida ：It can’t be hot in Florida now.（一定不）It must be hot in Florida now.（一定）2)NEEDN’T+HAVE DONEHe need not have seen much of the world, though he is an old ：He can’t have seen much of the world, for he is just a little must have seen much of the world, for he has been traveling so 、NEED與問(wèn)句 1)反意疑問(wèn)句的構(gòu)成 You needn’t go, need you? 2)答句的構(gòu)成Need he go?Yes, he must/has to/needs , he needn’t.（本條可參照must的用法）六、情態(tài)動(dòng)詞NEED與實(shí)義動(dòng)詞NEED 1)使用范圍作為實(shí)義動(dòng)詞的NEED有人稱(chēng)、數(shù)和時(shí)態(tài)的變化，使用范圍更為廣泛，不受句子類(lèi)型和時(shí)態(tài)的限制。在肯定句、過(guò)去時(shí)和將來(lái)時(shí)的句子中，一般使用作為實(shí)義動(dòng)詞的NEED。He needs to see a doctor straightaway.（此處needs to不能換做need，因?yàn)楸揪涫强隙ň洌￤ill he need to start earlier? 注：NEED TO BE DONE與NEED DOING可以互換，后者更為常用（這里的NEED均為實(shí)義動(dòng)詞）。2)含義差別NEEDN’T HAVE DONE與DIDN’T NEED TO DO表示“不必要”的時(shí)候，在意義上有所差別，前者表示“本不必做??”，實(shí)際上已經(jīng)做了（NEED為情態(tài)動(dòng)詞）；后者單純地表示“不必做??”（NEED為實(shí)義動(dòng)詞）。第四篇：英語(yǔ)情態(tài)動(dòng)詞用法歸納情態(tài)動(dòng)詞有具體的詞義，但也同助動(dòng)詞一樣，需要與其他詞語(yǔ)一起構(gòu)成句子的謂語(yǔ)，另外情態(tài)動(dòng)詞沒(méi)有人稱(chēng)和數(shù)的變化，情態(tài)動(dòng)詞后必須跟動(dòng)詞原形。那么接下來(lái)給大家分享一些關(guān)于英語(yǔ)情態(tài)動(dòng)詞用法歸納，希望對(duì)大家有所幫助。英語(yǔ)情態(tài)動(dòng)詞用法歸納 的用法：(1).表示能力、許可、可能性。表示能力時(shí)一般譯為“能、會(huì)”，即有種能力，尤其是生來(lái)具備的能力，此時(shí)may 和must均不可代替它。如：She can swim fast, but I can’，但我不能。I can see with my 。(2).表示許可，常在口語(yǔ)中。如：You can use my 。(3).表示推測(cè)，意為“可能”，常用于否定句和疑問(wèn)句中，此時(shí)can’t 譯為“ 不可能”。如：Can the news be true? 這個(gè)消息會(huì)是真的嗎?—Can it be our teacher?那個(gè)人有可能是我們老師嗎?—No, it can’t be our is on a visit to the Great 。咱們老師正在游覽長(zhǎng)城呢?！纠}】—I think Miss Gao must be in the said she would go there.— __be there, I have just been ’t ’t ’t ’t【解析】根據(jù)下文“我剛?cè)ミ^(guò)那兒”可知，應(yīng)為“ 不可能”，can’t 表示推測(cè)[答案] A：(1).can的過(guò)去式，意為“ 能、會(huì)”，表示過(guò)去的能力。如：He could write poems when he was 。(2).could在疑問(wèn)句中，表示委婉的語(yǔ)氣，此時(shí) could 沒(méi)有過(guò)去式的意思。如:Could you do me a favour? 你能幫我個(gè)忙嗎?—Could I use your pen? 我能用一下你的鋼筆嗎? —Yes, you 。(注意回答)：(1).表示請(qǐng)求、許可，比can 正式，如：May I borrow your bike? 我可以借你的自行車(chē)嗎?You may go home ?！纠}】—_______ I borrow your MP3? — you 【解析】 在此處表示請(qǐng)求，意為“ 做……可以嗎”。答案：A(2).表示推測(cè)，談?wù)摽赡苄?，意為?可能，或許”，一般用于肯定句中。如：It may rain 。She may be at .(3).may的過(guò)去式為might，表示推測(cè)時(shí)?？赡苄缘陀趍ay。如：He is away from might be ，可能是他生病了。(4).表示希望、祈求、祝愿，?？勺g為“祝愿”。通常是用may +主+V 例如：May you have a good 。May you be happy!祝你幸福!May you succeed!祝你成功!：(1).must 表示主觀看法，意為“必須、一定”。如：You must stay here until I e 。Must I hand in my homework right now? 我必須現(xiàn)在交作業(yè)嗎?(2)其否定形式mustn’t表示“ 一定不要 ” “千萬(wàn)別” “禁止, 不許”.如：You mustn’t play with 。You mustn’t be 。(3)對(duì)must引導(dǎo)的疑問(wèn)句，肯定回答為must，否定回答為needn’t 或 don’t have ：—Must I finish my homework?我現(xiàn)在必須完成作業(yè)嗎?—No, you needn’，你不必。(4)must表示有把握的推測(cè)，用于肯定句。如: The light is on, so he must be at home ，他現(xiàn)在肯定在家。注意其反意問(wèn)句的構(gòu)成形式：當(dāng)must表示肯定的判斷、推測(cè)時(shí)，其反意疑問(wèn)句要用實(shí)際問(wèn)句的助動(dòng)詞來(lái)構(gòu)成。如：She must have seen the film before，hasn’t she?(注意反意疑問(wèn)句的后半部分)You must have met uncle Wang in the shop yesterday，didn’t you?(注意反意疑問(wèn)句的后半部分)：(1).need 表示需要、必須，主要用于否定句和疑問(wèn)句中，其否定形式為needn’t，意為“沒(méi)有必要，不必”。用need 提問(wèn)時(shí)，肯定回答為 must，否定回答為 needn’t或don’t have to。如：—Need I stay here any longer? 我還有必要留在這兒?jiǎn)?—Yes, you ?！?needn’t /don’t have ，你不必。(2).need 還可以作實(shí)義動(dòng)詞，此時(shí)有人稱(chēng)、數(shù)和時(shí)態(tài)的變化，如果是人作主語(yǔ)后邊多接動(dòng)詞不定式。如：I need to do it right 。He needs to learn more about the 。如果是物作主語(yǔ)，一般用need doing 與 need to be done這種情況下應(yīng)注意兩點(diǎn)：①.主動(dòng)形式的動(dòng)名詞doing具有被動(dòng)的
