No, he cant be there, for I saw him in the library just now.(語(yǔ)氣很強(qiáng)，常用于疑問(wèn)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(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/dared) to do, dont(doesnt/didnt) need/dare to do八非謂語(yǔ)動(dòng)詞I.非謂語(yǔ)動(dòng)詞的分類、意義及構(gòu)成：非謂語(yǔ)形式構(gòu)成特征和作用時(shí)態(tài)和語(yǔ)態(tài)否定式復(fù)合結(jié)構(gòu)不定式to doto be doing to have doneto be doneto have been done在非謂語(yǔ)前加notfor 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(yǔ)分詞現(xiàn)在分詞doinghaving donebeing donehaving 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(yǔ)過(guò)去分詞done動(dòng)名詞doinghaving donebeing donehaving been donesbs doing具有名詞的作用在句中做主、賓、定和表語(yǔ)II. 做賓語(yǔ)的非謂語(yǔ)動(dòng)詞比較：情況常用動(dòng)詞只接不定式做賓語(yǔ)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(yǔ)的動(dòng)詞或短語(yǔ)mind, miss, enjoy, imagine, practise, suggest, finish, escape, excuse, appreciate, admit, prevent, keep, dislike, avoid, risk, resist, considercant 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/forget/regret to do（指動(dòng)作尚未發(fā)生）remember/forget/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)果）mean to do（打算做，企圖做）mean doing （意識(shí)是，意味著）cant help to do（不能幫忙做） cant help doing（忍不住要做）III.非謂語(yǔ)動(dòng)詞做賓語(yǔ)補(bǔ)足語(yǔ)的區(qū)別：常見動(dòng)詞與賓語(yǔ)的邏輯關(guān)系及時(shí)間概念例句不定式ask, beg, expect, get, order, tell, want, wish, encourage主謂關(guān)系。強(qiáng)調(diào)動(dòng)作將發(fā)生或已經(jīng)完成I heard him call me several times.have, notice, see, watch, hear, feel, let, make現(xiàn)在分詞notice, see, watch, hear, find, keep, have, feel主謂關(guān)系。強(qiáng)調(diào)動(dòng)作正在進(jìn)行，尚未完成I found her listening to the radio.過(guò)去分詞動(dòng)賓關(guān)系。動(dòng)作已經(jīng)完成，多強(qiáng)調(diào)狀態(tài)We found the village greatly changed.IV. 非謂語(yǔ)動(dòng)詞做定語(yǔ)的區(qū)別：區(qū)別舉例不定式與被修飾詞往往有動(dòng)賓關(guān)系，一般式表示將來(lái)，進(jìn)行式表示與謂語(yǔ)動(dòng)作同時(shí)發(fā)生，完成式表示在謂語(yǔ)動(dòng)詞之前發(fā)生I have a lot of papers to type.I have a lot of papers to be typed.動(dòng)名詞通常指被修飾詞的用途，無(wú)邏輯上的任何關(guān)系Shall we go to the swimming pool?現(xiàn)在分詞與被修飾詞之間是主謂關(guān)系，表示動(dòng)作與謂語(yǔ)動(dòng)作同時(shí)發(fā)生the boiling water / the boiled waterthe developing country/the developed countrythe falling leaves / the fallen leaves過(guò)去分詞與被修飾詞之間是被動(dòng)關(guān)系，表示動(dòng)作發(fā)生在謂語(yǔ)動(dòng)作之前，現(xiàn)已經(jīng)完成V. 非謂語(yǔ)動(dòng)詞做主語(yǔ)和表語(yǔ)的區(qū)別：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. (dream, business, wish, idea, plan, duty, task做主語(yǔ)時(shí)常用)動(dòng)名詞與不定式的功能區(qū)別不大，然而它更接近于名詞，表示的動(dòng)作比較抽象，或者泛指習(xí)慣性的動(dòng)作，有時(shí)也可以用it做形式主語(yǔ)，做表語(yǔ)時(shí)可以和主語(yǔ)互換位置。It is no use saying that again and again.Teaching is my job.分詞無(wú)名詞的性質(zhì)，不能做主語(yǔ)。但是有形容詞的性質(zhì)，可以做表語(yǔ)，多表明主語(yǔ)的特征性質(zhì)或者狀態(tài)等，可被very, quite, rather等副詞修飾?，F(xiàn)在分詞多含有“令人”之意，說(shuō)明主語(yǔ)的性質(zhì)特征，多表示主動(dòng)，主語(yǔ)多為物。過(guò)去分詞一般表示被動(dòng)或主語(yǔ)所處的狀態(tài)，含有“感到”之意，主語(yǔ)多是人。The situation is encouraging.The book is well written.(常見分詞有astonishing, moving, tiring, disappointing, puzzling, shocking, boring, amusing及其-ed形式)九定語(yǔ)從句I.定語(yǔ)從句起了形容詞的作用，在句中修飾一個(gè)名詞或代詞。被修飾的詞叫做先行詞，引導(dǎo)定語(yǔ)從句的詞叫關(guān)系詞，他的作用一是放在先行詞與定語(yǔ)從句中間起了連接作用，二是在從句中擔(dān)當(dāng)一個(gè)成分，并與先行詞保持?jǐn)?shù)的一致。關(guān)系詞先行詞從句成分例句備注關(guān)系代詞who人主語(yǔ)Do
