34、過去發生的動作或存在的狀況，但和現在有聯系，強調的是對現在造成的影響或結果，它不能同表示過去的時間狀語連用，漢譯英時可加“已經”等詞。簡言之，利用過去，說明現在。如：I have already read the novel written by the world-famous writer.

35、Beijing for ten years.（只說明在北京住過十年，與現在無關）3. 現在完成時與現在完成進行時的區別：兩者都可以表示“從過去開始一直持續到現在”，在含義上如著重表示動作的結果時，多用現在完成時，如著重表示動作一直在進行，即動作的延續性時，則多用現在完成進行時。一般不能用于進行時的動詞也不能用于現在完成進行時。I have read that book.我讀過那本書了。I have been reading that book all the morning. 我早上一直在讀那本書。4. 一般將來時的表達方式：將來時用法例句1will/shall+動詞原形表示將來發生的動作或存

36、在的狀態My sister will be ten next year.2be going to+動詞原形含有“打算，計劃，即將”做某事，或表示很有可能要發生某事Its going to clear up.Were going to have a party tonight.3be + doing 進行時表示將來go, come, start, move, leave, arrive等詞可用進行時表示按計劃即將發生的動作He is moving to the south.Are they leaving for Europe? 4be about to + 動詞原形表示安排或計劃中的馬上就要發

38、s/are asked6過去進行時was/were being asked2一般過去時was/were asked7現在完成時have/has been asked3一般將來時shall/will be asked8過去完成時had been asked4過去將來時should/would be asked9將來完成時will/would have been asked5現在進行時am/is/are being asked10含有情態動詞的can/must/may be asked注意事項被動語態的否定式是在第一個助動詞或情態動詞后加not，短語動詞的被動態不可漏掉其中介副詞。固定結構bego

39、ing to, used to, have to, had better變為被動態時，只需將其后的動詞變為被動態。 如：Trees should not be planted in summer. / The boy was made fun of by his classmates.Newspapers used to be sent here by the little girl.漢語有一類句子不出現主語，在英語中一般可用被動結構表示。如：It is believed that It is generally considered that It is said thatIt is wel

40、l known that It must be pointed out that It is supposed thatIt is reported that It must be admitted that It is hoped that下面主動形式常表示被動意義：如：The window wants/needs/requires repairing. The book is worth reading twice.The door wont shut. / The play wont act. The clothes washes well. / The book sells well.

41、The dish tastes delicious. / Water feels very cold.下面詞或短語沒有被動態：leave, enter, reach, become, benefit, cost, equal, contain, last, lack, fit, fail, have, appear, happen, occur, belong to, take place, break out, come about, agree with, keep up with, consist of, have on, lose heart等等七情態動詞I. 情態動詞基本用法：情態動

42、詞用法否定式疑問式與簡答can能力（體力，智力，技能）允許或許可（口語中常用）可能性（表猜測，用于否定句或疑問句中）can not / cannot /cant doCando?Yes,can.No,cant.couldcouldnt domay可以（問句中表示請求）可能，或許（表推測）祝愿（用于倒裝句中）may not do Maydo? Yes,may.No,mustnt/cant.mightmight not doMightdo? Yes,mightNo,might not.must必須，應該（表主觀要求）肯定，想必（肯定句中表推測）must not/mustnt doMustdo? Y

43、es,must.No,neednt/dont have to.have to只好，不得不（客觀的必須，有時態人稱變化）dont have to doDohave to do?Yes,do. No,dont.ought to應當（表示義務責任，口語中多用shouldought not to/oughtnt to doOughtto do?Yes,ought.

45、 to dodidnt use to doUsedto do?Yes,used. No,use(d)nt.Diduse to do?Yes,did. No,didnt.II. 情態動詞must, may, might, could, can表示推測：以must為例。must + do(be)是推測現在存在的一般狀態進行；must + be doing 推測可能正在進行的事情；must +have done是推測可能已經發生過的事情。1. must“肯定，一定”語氣強，只用于肯定句中。He must be a man from America. / He must be talking with

46、 his friend. / He must have already arrived there.2. may和might“也許”，后者語氣弱，更沒有把握。可用于肯定句和否定句。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cant語氣強，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.（推測某事本來可

47、能發生，但實際上沒有發生）Can he be in the office now? No, he cant be there, for I saw him in the library just now.(語氣很強，常用于疑問句和否定句中)III. 情態動詞注意點：1. can和be able to: 都可以表示能力。但be able to可以表達“某事終于成功”，而can無法表達此意。Be able to有更多的時態。另外，兩者不能重疊使用。2. used to和would: used to表示過去常常做現在已經不再有的習慣，而would只表示過去的習慣或喜好，不涉及現在。3. need和d

48、are作情態動詞和實義動詞的區別：兩者作情態動詞時常用于否定句和疑問句。其形式為：neednt/darent do；Need/daredo?做實義動詞時可用于肯定句，否定句和疑問句。其形式為：need(needs/needed)/dare(dares/dared) to do, dont(doesnt/didnt) need/dare to do八非謂語動詞I. 非謂語動詞的分類、意義及構成：非謂語形式構成特征和作用時態和語態否定式復合結構不定式to doto be doing to have doneto be doneto have been done在非謂語前加notfor sb. to

49、 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、賓補和狀語過去分詞done動名詞doinghaving donebeing donehaving been donesbs doing具有名詞的作用在句中做主、賓、定和表語II. 做賓語的非謂語動詞比較：情況常用動詞只接不定式做賓語的動詞hope, want, offer, long, fail, expect, wish, ask, decide, pretend, manage, agr

50、ee, afford, determine, promise, happen只接動名詞做賓語的動詞或短語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,

51、 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作，接動名詞多指一般或習慣行為）need, want, require（接動名詞主動形式表示被動意義，若接不定式則應用被動形式）意義相反stop to do 停止手

52、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（指動作尚未發生）remember/forget/regret doing（指動作已經發生）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（設法，努力去做，盡力）try doing（試試去做，看有何結果）mean to do（打算做，企圖做）mean doing （意識是，意味著）cant help to do（不能幫忙做） cant help doing（忍不住要做）III.非謂語動詞做賓語補足語的區別：常見動詞與賓語的邏

53、輯關系及時間概念例句不定式ask, beg, expect, get, order, tell, want, wish, encourage主謂關系。強調動作將發生或已經完成I heard him call me several times.have, notice, see, watch, hear, feel, let, make現在分詞notice, see, watch, hear, find, keep, have, feel主謂關系。強調動作正在進行，尚未完成I found her listening to the radio.過去分詞動賓關系。動作已經完成，多強調狀態We fou

54、nd the village greatly changed.IV. 非謂語動詞做定語的區別：區別舉例不定式與被修飾詞往往有動賓關系，一般式表示將來，進行式表示與謂語動作同時發生，完成式表示在謂語動詞之前發生I have a lot of papers to type.I have a lot of papers to be typed.動名詞通常指被修飾詞的用途，無邏輯上的任何關系Shall we go to the swimming pool?現在分詞與被修飾詞之間是主謂關系，表示動作與謂語動作同時發生the boiling water / the boiled waterthe deve

55、loping country/the developed countrythe falling leaves / the fallen leaves過去分詞與被修飾詞之間是被動關系，表示動作發生在謂語動作之前，現已經完成V. 非謂語動詞做主語和表語的區別：區別舉例不定式多表示一個特定的具體的將來的動作，做主語時可以借助于it把不定式移到句子后面。做表語有時可和主語交換位置，而且意義不變，并且還能用what來提問主語或表語。My dream is to become a teacher.To obey the law is important. (dream, business, wish, i

56、dea, plan, duty, task做主語時常用)動名詞與不定式的功能區別不大，然而它更接近于名詞，表示的動作比較抽象，或者泛指習慣性的動作，有時也可以用it做形式主語，做表語時可以和主語互換位置。It is no use saying that again and again.Teaching is my job.分詞無名詞的性質，不能做主語。但是有形容詞的性質，可以做表語，多表明主語的特征性質或者狀態等，可被very, quite, rather等副詞修飾。現在分詞多含有“令人”之意，說明主語的性質特征，多表示主動，主語多為物。過去分詞一般表示被動或主語所處的狀態，含有“感到”之意，

57、主語多是人。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)九定語從句I. 定語從句起了形容詞的作用，在句中修飾一個名詞或代詞。被修飾的詞叫做先行詞，引導定語從句的詞叫關系詞，他的作用一是放在先行詞與定語從句中間起了連接作用，二是在從句中擔當一個成分，并與先行詞保持數的一致。關系詞先行詞從句成分例句備注關系副詞when時間時間狀語I will neve

58、r forget the day when we met there.可用on whichwhere地點地點狀語This is the house where I was born.可用in whichwhy原因原因狀語I cant imagine the reason why he turned down my offer.可用for which關系詞先行詞從句成分例句備注關系代詞who人主語Do you know the man who is talking with your mother?whom, which和that在從句中做賓語時，常可以省略，但介詞提前時后面關系代詞不能省略，也

59、不可以用thatwhom人賓語Mr. Smith is the person with whom I am workingwhose人，物定語I like those books whose topics are about history.The boy whose father works abroad is my deskmate. that人，物主語，賓語A plane is a machine that can fly.She is the pop star (that) I want to see very much.which物主語，賓語The book (which) I ga

60、ve you was worth $10.as人，物主語，賓語He is such a person as is respected by all of us.This is the same pen as I lost yesterday. as做賓語一般不省略II. that與which, who, whom的用法區別：情況用法說明例句只用that的情況先行詞為all, everything, anything, nothing, little, much,等不定代詞時。先行詞被all, any, every, each, much, little, no, some, few等修飾時先行
