45、：以must為例。must + do(be)是推測(cè)現(xiàn)在存在的一般狀態(tài)進(jìn)行；must + be doing 推測(cè)可能正在進(jìn)行的事情；must +have done是推測(cè)可能已經(jīng)發(fā)生過(guò)的事情。1. must“肯定，一定”語(yǔ)氣強(qiáng)，只用于肯定句中。He must be a man from America. / He must be talking with his friend. / He must have already arrived there.2. may和might“也許”，后者語(yǔ)氣弱，更沒(méi)有把握。可用于肯定句和否定句。He may not be at home. / They migh

47、情態(tài)動(dòng)詞注意點(diǎn)：1. can和be able to: 都可以表示能力。但be able to可以表達(dá)“某事終于成功”，而can無(wú)法表達(dá)此意。Be able to有更多的時(shí)態(tài)。另外，兩者不能重疊使用。2. used to和would: used to表示過(guò)去常常做現(xiàn)在已經(jīng)不再有的習(xí)慣，而would只表示過(guò)去的習(xí)慣或喜好，不涉及現(xiàn)在。3. need和dare作情態(tài)動(dòng)詞和實(shí)義動(dòng)詞的區(qū)別：兩者作情態(tài)動(dòng)詞時(shí)常用于否定句和疑問(wèn)句。其形式為：neednt/darent do；Need/daredo做實(shí)義動(dòng)詞時(shí)可用于肯定句，否定句和疑問(wèn)句。其形式為：need(needs/needed)/dare(dares/

55、：區(qū)別舉例不定式多表示一個(gè)特定的具體的將來(lái)的動(dòng)作，做主語(yǔ)時(shí)可以借助于it把不定式移到句子后面。做表語(yǔ)有時(shí)可和主語(yǔ)交換位置，而且意義不變，并且還能用what來(lái)提問(wèn)主語(yǔ)或表語(yǔ)。My dream is to become a teacher.To obey the law is important.
