初中英語(yǔ)常見情態(tài)動(dòng)詞的用法(存儲(chǔ)版)

  

【正文】 動(dòng)詞要跟帶to的不定式,而在否定句和疑問(wèn)句中的不定式符號(hào)to可要可不要。 * If you dare speak to me like that, you will be sorry. 要是你再敢這樣對(duì)我說(shuō)話,你就會(huì)后悔的。 No, she doesn’,她不需要。 ②need作實(shí)義動(dòng)詞時(shí),有人稱和數(shù)的變化,可用于肯定句、否定句及疑問(wèn)句。 四、need 的用法 ①need作情態(tài)動(dòng)詞時(shí),只用于否定句、疑問(wèn)句和條件句中。例如:* The road can be very crowded at this time.(本句的意思只是說(shuō)道路此時(shí)有擁擠的可能,但實(shí)際上也有可能不擁擠)* The road may be very crowded at this time.(本句隱含的意思是道路此時(shí)可能真的擁擠)* Mr Reed is in poor health .He can be ill at any time.(表示有患病的可能,但實(shí)際上這個(gè)人此時(shí)也許仍然很健康。 * 在否定結(jié)構(gòu)中:don39。 例如: * He looks very happy. He might not have known the result.③ may 還可用來(lái)表示祝愿。二、may / might 的用法 ① 表示“許可”,意思是“可以”。 * He can’t be a millionaire. 他不可能是個(gè)百萬(wàn)富翁。例如:*I could walk when I was eight months old. * I was able to walk 50 meters in a minute when I was eight months old. * He was able to swim halfway before he collapsed(動(dòng)詞:衰退) . * He was able to translate the article without a dictionary. * I couldn’t /wasn’t able to play the piano when I was at school. * She could play the piano when she was only six. * At that time I could still read without spectacles. * He got so drunk that he couldn’t /wasn’t able to find the front door . ○ 另外,can 可用于人或其它事物作主語(yǔ)的句子中,be able to 只用于人和動(dòng)物作主語(yǔ)的句子中。can 表示現(xiàn)在的能力時(shí),既可表示做某樁具體事情的“能力”,也可泛指一般的能力(《新編英語(yǔ)語(yǔ)法教程》,可用于肯定句,否定句,疑問(wèn)句等句中。can常用于否定句,疑問(wèn)句中,用于肯定句時(shí)表示理論上的可能性(即從理論或邏輯上分析是可能的,但實(shí)際未必會(huì)發(fā)生)。* What can [could] they be doing? 他們會(huì)在干什么呢?* We could go there this summer. 今年夏天我們可能要去那兒。例如: * You may keep the books for ten days . * Students may not stay out after midnight .(注意:讀may not 時(shí)重音要放在not上) * May /Might I have a few words with you ? (注意:表示征求許可時(shí)的回答,肯定可用:* Yes, you can /may.*Yes, please .否定可用:* No, you mustn’t. * Please don’t.* No, you may not.) (注意:may not = mayn’t might not = mightn’t ) (注意:may not 也可表示一般的不許可,即表示根據(jù)一般規(guī)定的不許可,而不是說(shuō)話人不許可。 注意:must開頭的一般疑問(wèn)句的回答: * Must I live here ? Yes ,you must .(肯定) No , you don’t have to .或 No ,you needn’t .(否定) 注意:must主要表示現(xiàn)在或?qū)?lái)的必須,但有時(shí)(如在間接引語(yǔ)中)也可表過(guò)去(=had to),。其否定形式是 can’t (不可能)。如:* She can’t be in the office now. 她現(xiàn)在不可能在辦公室。 No, you needn’t. 不,你不需要。(注:如need作實(shí)義動(dòng)詞,句子主語(yǔ)
