II. 情態(tài)動(dòng)詞 must, may, might, could, can表示推測(cè): 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)生過的事情。 1. must“肯定,一定”語氣強(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”,后者語氣弱,更沒有把握??捎糜诳隙ň浜头穸ň洹? He may not be at home. / They might have finished their task. 3. can和 could“可能”, could 表示可疑的可能性,不及 can’t語氣強(qiáng),用于肯定、否定、疑問句中。 The weather in that city could be cold now. We could have walked there。 it was so near.(推測(cè)某事本來可能發(fā)生,但實(shí)際上沒有發(fā)生) Can he be in the office now? No, he can’t be there, for I saw him in the library just now.(語氣很強(qiáng),常用于疑問句和否定句中 ) III. 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表示過去常常做現(xiàn)在已經(jīng)不再有的習(xí)慣,而 would只表示過去的習(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句。其形式為: needn’t/daren’t do; Need/dare…do…? 做實(shí)義動(dòng)詞時(shí)可用于肯定句,否定句和疑問句。其形式為: need(needs/needed)/dare(dares/dared) to do, don’t(doesn’t/didn’t) need/dare to do 八.非謂語動(dòng)詞 I. 非謂語動(dòng)詞的分類、意義及構(gòu)成: 非謂語形式 構(gòu)成 特征和作用 時(shí)態(tài)和語態(tài) 否定式 復(fù)合結(jié)構(gòu) 不定式 to do to be doing to have done to be done to have been done 在非謂語前加not for sb. to do sth. 具有名詞,副詞和形容詞的作用 在句中做主、賓、定、表和狀語 分詞 現(xiàn)在分詞 doing having done being done having been done 具有副詞和形容詞的作用 在句中做定、表、賓補(bǔ)和狀語 過去分詞 done 動(dòng)名詞 doing having done being done having been done sb’s doing 具有名詞的作用 在句中做主、賓、定和表語 II. 做 賓語的非謂語動(dòng)詞比較: 情況 常用動(dòng)詞 只接不定式做賓語的動(dòng)詞 hope, want, offer, long, fail, expect, wish, ask, decide, pretend, manage, agree, afford, determine, promise, happen 只接動(dòng)名詞做賓語的動(dòng)詞或短語 mind, miss, enjoy, imagine, practise, suggest, finish, escape, excuse, appreciate, admit, prevent, keep, dislike, avoid, risk, resist, consider can’t help, feel like, succeed in, be fond of, object to, get down to, be engaged in, insist on, think of, be proud of, take pride in, set about, be afraid of, be tired of, look forward to, devote oneself to, be worth, be busy, pay attention to, stick to 兩者都可以 意義基本相同 begin, start, like, love, hate, prefer, continue(接不定式多指具體的動(dòng)作,接動(dòng)名詞多指一般或習(xí)慣行為) need, want, require(接動(dòng)名詞主動(dòng)形式表示被動(dòng)意義,若接不定式則應(yīng)用被動(dòng)形式) 意義相反 stop to do 停止手中事,去做另一件事 stop doing 停止正在做的事 意義不同 remember/fet/regret to do(指動(dòng)作尚未發(fā)生) remember/fet/regret doing(指動(dòng)作已經(jīng)發(fā)生) go on to do(接著做另外一件事) go on doing(接著做同一件事) try to do(設(shè)法,努力去做,盡力) try doing(試試去做,看有何結(jié)
