高中英語(yǔ)語(yǔ)法要點(diǎn)易錯(cuò)點(diǎn)整理

1、 高考語(yǔ)法要點(diǎn)和易錯(cuò)點(diǎn) 語(yǔ)法一 =從句從句的做題思路=判定是什么從句一、關(guān)于定語(yǔ)從句（前提：懂得判斷是哪一種從句）1 修飾某一名詞或代詞的句子叫定語(yǔ)從句。2 連接詞that/which/who/whom/whose/when/where/why/as What/how>< 既起連接作用/有充當(dāng)句子成分3 先行詞 n./pron -被定語(yǔ)從句修飾的根據(jù)先行詞選擇連接詞物：which/that/whose人：who/whom/that/whose時(shí)間：when/which/that地點(diǎn)：where/which /thatReason: 從句完整why/for which；從句不完整wh

2、ich/that/-Way: 從句完整 in which/that/-; 從句不完整which/that/-I dont like the way you speak to your parents.He found the way was reasonable to solve the problem. 答案：in which/that；which/that 當(dāng)先行詞與連接詞后面的名詞n存在所屬關(guān)系時(shí)（的） 物：whose+n.=of which +the +n.=the +n.+of which 人：whose +n.=of whom +the +n.= the +n.+ of whom

3、The room, of which the window faces south is mine. The girl, whose father died is our monitor.4 只能用that 不能用which(重點(diǎn)前5種情況)（1）當(dāng)先行詞是不定代詞，如all，everything，anything，nothing，much，few，little，none，the one等。All that can be done has been done.（2）先行詞被all, few，little，no，every 等詞修飾時(shí)。There is no difficulty that we

4、 cant overcome.（3）先行詞被序數(shù)詞或形容詞的最高級(jí)修飾時(shí)。This is the first letter that Ive written in Japanese.（4）先行詞被the only, the very, the last 等修飾時(shí) This is the very book that I am looking for.（5）當(dāng)先行詞既有人又有物時(shí)。They talked about the teachers and schools that they had visited.（6）當(dāng)先行詞是系動(dòng)詞be后面的表語(yǔ)或連接詞本身是從句的表語(yǔ)時(shí)。China isnt t

5、he country that she used to be 50 years ago.（7）當(dāng)主句是以who，which或what開(kāi)頭的特殊疑問(wèn)句時(shí)。Who is the man that is waiting at the bus stop？5 永遠(yuǎn)不用that =介詞/逗號(hào)之后6 當(dāng)先行詞是時(shí)間/地點(diǎn)時(shí) when /where /that/which/-When=介詞+which=介詞+時(shí)間Where=介詞+which = 介詞+地點(diǎn)Which/that= 時(shí)間/地點(diǎn)當(dāng)從句完整時(shí)，用When/ Where/介詞+which當(dāng)從句不完整時(shí)，用which/that/-e.g. I still

6、 remember the days that/which/- we spent at the seaside last summer.This is the factory in which/ where his parents used to work.1.The library _ students often study was on fire last night.2.The library, _ was built in the 1930s, needs repairing.3.The library _ you visited yesterday was built in 199

7、0.4.Ill never forget the day _ we first met in the park.5.Ill never forget the time _ I spent on campus.6.Ill never forget the time _ was spent with you.答案：where/in which；which/that；which/that；when/on which；that/which；_that/which7. as與which的比較：（1）在非限制性定語(yǔ)從句中，均可替代整個(gè)主句. 如從句在主句之后，兩者皆可用；如從句在主句之前，用as。They

8、 failed in the exam，as/which is natural.As is known to all，the earth moves around the sun.（2）as“正如，就像” Which “這一點(diǎn)/這個(gè)/這件事” He is careless, which caused the accident. He is late again, as/which we expected.8. 當(dāng)先行詞被the same，such，so修飾時(shí)， This is the same book as you bought yesterday. 同一類(lèi) .that 同一個(gè)This wa

9、s so difficult a problem as we couldnt work out.（后面句子不完整）This was so difficult a problem that we couldnt work it out.（后面句子完整）This was such a difficult problem 9.另外，定語(yǔ)從句中謂語(yǔ)動(dòng)詞的數(shù)應(yīng)與先行詞的數(shù)相一致。如：Mr. Jackson is the only foreigner that is present at the party.0He is one of the students who were praised by th

10、e teacher.解析：在句中，先行詞foreigner被only修飾，強(qiáng)調(diào)只有一個(gè)，所以從句中謂語(yǔ)動(dòng)詞用單數(shù)形式，而在句中，who引導(dǎo)的定語(yǔ)從句修飾先行詞the students為復(fù)數(shù)，所以從句謂語(yǔ)動(dòng)詞應(yīng)為復(fù)數(shù)。感悟：學(xué)生之所以在這一點(diǎn)上經(jīng)常出錯(cuò)，主要是對(duì)定語(yǔ)從句的理解不夠深刻，分辨不出主句和從句，對(duì)句子成分的把握也不到位，搞不清關(guān)系代詞或關(guān)系副詞在從句中充當(dāng)何種句子成分。所以要做好這一類(lèi)題，要首先弄清關(guān)系代詞和關(guān)系副詞的用法，而且應(yīng)善于分辨和分析句子結(jié)構(gòu)及其相應(yīng)成分，這樣才能對(duì)癥下藥，快速準(zhǔn)確地找到瓿之所在。二、名詞性從句 主語(yǔ)從句What I say is true賓語(yǔ)從句He won

11、t believe what I say.表語(yǔ)從句That is what I said.同位語(yǔ)從句I told them the news that Rockets won the game today.區(qū)別什么從句應(yīng)看主句，主句不完整時(shí)從句肯定是名詞性從句。主句完整時(shí)，從句可能是定語(yǔ)從句，狀語(yǔ)從句，或者同位語(yǔ)從句。I have forgotten where we went yesterday.Where we went yesterday is covered with all kinds of flowers.Oh! This is where we came yesterday. T

12、his is the place where we came yesterday.Here, he made the promise that he would come here 10 years later.I will make a mark where he made the promise.需要用什么引導(dǎo)詞看從句。名詞性從句中缺什么意思用什么意思的引導(dǎo)詞; 缺名詞性成份時(shí)，指人用who/whom，指物用what; 不缺意思和成份時(shí)用that。That 只有在賓語(yǔ)從句中可以省略。1. _ the Olympic Games will be held in Beijing is know

13、n.A.不填 B. Whenever C. What D. When2. There is a common belief among them _ rubbish can and should be put to good use.A. which B. if C. whether D. that3. Hes bought a cottage for _ he retires, with the money he saved.A. When B. where C. what D. which (哪一個(gè)、哪一些)答案DDA-It is known to all that Taiwan belo

14、ngs to China.-Do you think it possible that we take over Taiwan?-Of course. It 經(jīng)常在句中當(dāng)形式主語(yǔ)、賓語(yǔ)，代替真正的主語(yǔ)、賓語(yǔ)，以避免頭重腳輕。It is pretty well understood _ controls the flow of carbon dioxide in and out of the atmosphere today.A. That B. when C. what D. howWhy dont you bring _ to his attention that you are too b

15、usy to do it?A. This B. what C. thatD. it答案CD表“是否”時(shí)只用whether不用if:1. Whether the president will come is not known yet. (主從)2. The problem is whether we need it.（表從）3. The problem whether we will build another school hasnt been settled.（同位語(yǔ)從句）4. He was worried about whether he passed the English exami

16、nation. （介詞之后）5. It doesnt matter whether she will come or not. （whether or /or not）6. I dont know whether to go.（動(dòng)詞不定式之前）區(qū)別：that引導(dǎo)的定語(yǔ)從句與同位語(yǔ)從句定語(yǔ)從句與前面的的名詞是修飾與被修飾的關(guān)系，“的名詞”，而同位語(yǔ)從句是用來(lái)說(shuō)明前面名詞的內(nèi)容。與that從句同位的名詞必須是一些表示事實(shí)或概念的抽象名詞，如fact,news,belief,truth,reply等。That在定語(yǔ)從句中必須作成分，可用which或who/whom代替，而that在同位語(yǔ)從句中不充當(dāng)

17、任何句子成分，只起連接作用。如：Along with the letter was his promise that he would visit me this coming Christmas. Do you still remember the chicken farm that we visited three months ago.解析：在句中，that引導(dǎo)同位語(yǔ)從句解釋說(shuō)明promise的內(nèi)容，that不充當(dāng)任何句子成分，只起連接作用，而在句中，that在其引導(dǎo)的定語(yǔ)從句中作動(dòng)詞visited的賓語(yǔ)，對(duì)先行詞the chicken farm起修飾作用。感悟：學(xué)生之所以在這一點(diǎn)上容易

18、出錯(cuò)，主要還是因?yàn)閷?duì)定語(yǔ)從句的理解不夠深刻，分辨不出that在從句中是否充當(dāng)了句子成分，因此，還需在句子分析上下功夫，并且搞清何謂同位語(yǔ)從句。三、 狀語(yǔ)從句（主句完整，從句和主句之間不存在修飾關(guān)系的，一般就是狀從）1. 關(guān)于when/while/as 都有“當(dāng)時(shí)” When I arrived, he had already left.Mary asked me to care for her pet while she was away. （當(dāng)時(shí)） As the sun set in the west, it became darker and darker. As time goes by

19、/as the economy developsWhen (正在這時(shí))Be about to do. When Be doing whenHad just done whenBe on the point of doing when whileHe likes pop music while I am fond of classical music. (而)Mary asked me to care for her pet while she was away. （當(dāng)時(shí)）While I understand what you say, I cant agree with you. （雖然） a

20、sA. 隨著+句子 as time went by as the economy develops B. 像 + 句子 It looks a little ugly as it is .C. 作為 +短語(yǔ) treat / regard / consider / think of / look on as （把 作為來(lái)對(duì)待）D. 因?yàn)?句子 because /since/forAs you are Senior 3 students, you should spare no effort / pains to study. E. 正如 / 就像 As is known to all/we all

21、 know, Taiwan belongs to China. As an old saying goes, its not until the Dragon Boat Festival that we can put away warm clothes.2. 關(guān)于since/before/untilIt is/has been several months since we last spent the holiday in the country together.It was ten years since we had had such a wonderful time.Before

22、He left before I could say “thank you” to him. 來(lái)不及Three years passed before I knew it. 才It wont be long before we have a monthly exam.It will be ten years before we meet again. It was ten years before they met again.Until/till (主句謂語(yǔ)持續(xù)性)Not until(主句謂語(yǔ)短暫性)George worked for IBM until/till 2000. 直到靠近，我才

23、認(rèn)出他。Until he came up to me, I recognized him. （此句錯(cuò)誤）=I didnt recognize him until he came up to me.3. 關(guān)于“一就” Hardly when No sooner than As soon as The moment/time/minute/second +句子 Immediately/instantly/directly +句子 On doing/名詞Hardly (No sooner) had I got home when (than) the rain poured down.The mom

24、ent she saw the robber, she screamed.Instantly he saw the drowning girl, he jumped into the river.Upon arrival/ On arrival / On arriving, I will pay a visit to you first.4. It is/was +時(shí)間點(diǎn)+when 與強(qiáng)調(diào)句型的區(qū)別 It was midnight I fell asleep. A. when B. that C. while D. becauseIt was at noon we arrived in the

25、 village. A. before B. while C. when D. that答案AD5.Unless 如果不（除非）/if 如果 _you go all out to do the work, I don't think you can achieve your goal as planned.A. UnlessB. Even C. SinceD. TillHe never speaks _ he is spoken to, for he is not much of a speaker.A.when B.if C.unless D.until答案AC6. as if(th

26、ough) 似乎/仿佛/好像 +真實(shí)/虛擬7. even if /though 即使8. in case/for fear that 以防/惟恐9. What/whatever/no matter what; how/however/no matter howWhat(ever) +名詞 How(ever) +形容詞/副詞 Whatever difficulties we meet with, it is best to face them and try to solve them.However late it is, Ill wait for you.No matter how busy

27、 he is, he is ready to help others.No matter +疑問(wèn)詞=引導(dǎo)狀從 疑問(wèn)詞 +ever=引導(dǎo)名從/狀從Whatever you say, I wont believe you. = No matter what（狀語(yǔ)從句）I wont believe whatever you say. = anything that（賓語(yǔ)從句） Whoever / No matter who comes, dont let him in. （狀語(yǔ)從句） Whoever / Anyone who leaves last should turn off the light

28、s. （主語(yǔ)從句） 10. Where +句子 （特別是引導(dǎo)地點(diǎn)狀從和定從的區(qū)別） I have forgotten where we went yesterday.Where we went yesterday is covered with all kinds of flowers.Oh! This is where we came yesterday. This is the place where/in which we came yesterday.I will make a mark where the teacher emphasizes.語(yǔ)法二 =非謂語(yǔ)非謂語(yǔ)做題思路1判斷主被

29、動(dòng)2判斷時(shí)間（要發(fā)生/正在進(jìn)行/已完成）非謂語(yǔ)與其邏輯主語(yǔ)（即動(dòng)作的執(zhí)行者或承受者）之間有三種關(guān)系，如為主謂關(guān)系，則用現(xiàn)在分詞或不定式的主動(dòng)式；如為被動(dòng)關(guān)系則用過(guò)去分詞、現(xiàn)在分詞的被動(dòng)（強(qiáng)調(diào)動(dòng)作正在進(jìn)行）或不定式的被動(dòng)式（動(dòng)作將進(jìn)行）；如既無(wú)主動(dòng)也無(wú)被動(dòng)關(guān)系則只能用狀語(yǔ)從句或獨(dú)立主格結(jié)構(gòu)（即非謂語(yǔ)加上自己的邏輯主語(yǔ)）。Judging/considering/genrally speaking/supposing指說(shuō)話者的動(dòng)作，故只用主動(dòng)式。如：Having been ill in bed for nearly a month , he had a hard time passing the e

30、xam.解析：從這個(gè)句子可以看出，句詞的邏輯主語(yǔ)與句子的主語(yǔ)he一致，并且是主謂關(guān)系，所以用了現(xiàn)在的分詞作狀語(yǔ)，同時(shí)，分詞的動(dòng)作明顯地發(fā)生在句子的謂語(yǔ)動(dòng)詞動(dòng)作之前，故采用了現(xiàn)代分詞的完成式。In order to improve English , _.A. Jennys father bought her a lot of tapes.B. Jennys father bought a lot of tapes for herself.C. A lot of tapes were bought by Jenny.D. A lot of tapes were bought by Jenny f

31、ather.解析：根據(jù)不定式短語(yǔ)我們可以推知，句子的邏輯主語(yǔ)應(yīng)該是人而不是物，所以，應(yīng)該排除CD，再就是應(yīng)該是Jenny提高自己的英語(yǔ)，而不是她爸爸，故答案先B.，we decided to go out for a walk.A. It is fine B. It fine C. Being fine D.It being fine解析：主句主語(yǔ)we與動(dòng)詞短語(yǔ)be fine之間既無(wú)主動(dòng)關(guān)系與無(wú)被動(dòng)關(guān)系，所以要加上自己的邏輯主語(yǔ)It，由于不存在主、被動(dòng)關(guān)系，故不能選C項(xiàng)，而應(yīng)該選D項(xiàng)。more attention, the trees could have grown better.A. Gi

32、ven B.To give C.Giving D. Having giving解析：give與主句的主語(yǔ)之間是被動(dòng)關(guān)系，故選A.如為主動(dòng)關(guān)系則選C.易出錯(cuò)的問(wèn)題一般都是學(xué)生在學(xué)習(xí)中對(duì)知識(shí)理解不深刻或能力欠缺的地方，應(yīng)及時(shí)糾錯(cuò)和建立“錯(cuò)題檔案”，還應(yīng)“借題發(fā)揮”，有意地把一些易錯(cuò)題予以歸類(lèi)，找出錯(cuò)誤根源，總結(jié)規(guī)律。非謂語(yǔ) =不能做謂語(yǔ)的動(dòng)詞形式 1 Doing 主動(dòng) 正在進(jìn)行 eg. The man standing there is my teacher.2 being done被動(dòng) 正在進(jìn)行 eg.I think the book being written by him will sell

33、 well.3 having done主動(dòng) 已經(jīng)完成 只能做狀語(yǔ) eg. Having finished his homework, he went out to play.4 having been done被動(dòng) 已經(jīng)完成 只能做狀語(yǔ) eg Having been taken care of well, the old man recovered soon.5 done 被動(dòng) 已經(jīng)完成 fallen leaves( 這里表完成，不表被動(dòng))6 （onlyjust）to do主動(dòng) 將來(lái)7 to be doing主動(dòng) 正在進(jìn)行8 to be done 被動(dòng) 將來(lái)9 to have done主動(dòng) 完

34、成10 （to have been） done被動(dòng) 完成非謂語(yǔ)Having done所表達(dá)的動(dòng)作在謂語(yǔ)動(dòng)作之前完成，一般放句首做狀語(yǔ)。非謂語(yǔ)doing所表達(dá)的動(dòng)作發(fā)生和謂語(yǔ)動(dòng)作幾乎同時(shí)進(jìn)行。Having worked hard all day, I went to bed early.Having experienced quite a few earthquakes in Hawaii already, I didnt take much notice.Having studied volcanoes now for many years, I am still amazed at thei

35、r beauty as well as their potential to cause great damage. Walking in the way of back home, suddenly I saw a store covered with smoke.、不定式表意料之外的結(jié)果，現(xiàn)在分詞表自然而然的結(jié)果。 I hurried home, only to find nobody in. His parents died early, leaving him alone. * only to do 與doing 作結(jié)果狀語(yǔ)的用法“ only to do” 做結(jié)果狀語(yǔ)表意料之外的結(jié)果，

36、尤指不愉快的結(jié)果。 “doing” 做結(jié)果狀語(yǔ)表示必然結(jié)果與主句之間含有邏輯上的因果關(guān)系。語(yǔ)法三 =虛擬語(yǔ)氣（一）if 虛擬從句主句與現(xiàn)在相反beweredodid Would/should/could/might+V原與過(guò)去相反Behad beendohad doneWould/should/could/might+have done/been與將來(lái)相反1.Bewere; dodid2.were to +V原3.should do Would/should/could/might+V原注：1、if I were you Were I you if I had finished it Had

38、ld have gone to Italy.Ive discovered I possess a large number of different talents and skills that I never would have thought were within me had it not been for my being open to trying new opportunities. 3、Without/but for=(要不是)Without you, I wouldnt have got full mark.（二）、If only/Wish+現(xiàn)在：bewere do d

39、id If only/Wish+過(guò)去：behad been dohad doneIf only/Wish+將來(lái)：could/should/would +doAs if/though 也適用It seems as if it is going to rain.It seems as if it were to rain.注：may you +V原(三)動(dòng)詞：Insist/suggest/advise/recommend/propose/order/command/demand/require/request /desire +(should)do 注：動(dòng)詞對(duì)應(yīng)的名詞和句型也用（should）do

40、表虛擬suggestion /order/adviceIts suggested/ordered that+（四）Its necessary/important/vital that(should) do (五) Its (high/about) time thatshould do/did (六) would rather +句子1、對(duì)現(xiàn)在/將來(lái)虛擬用did 2、對(duì)過(guò)去虛擬用had done 虛擬語(yǔ)氣在if 引導(dǎo)的條件句中的易錯(cuò)點(diǎn)。 if my lawyer had been here last Saturday, he would have prevented me from going.

41、 if you had studied hard at school, you would be a college student now.句子都是虛擬語(yǔ)氣在條件句中的使用，從句中都是假設(shè)過(guò)去的情況，所以用過(guò)去完成時(shí)，但在主句中，句依然指代過(guò)去的情況，謂語(yǔ)動(dòng)詞是would have done，而中含有一個(gè)表示現(xiàn)在的時(shí)間狀語(yǔ)now,這樣就必須將其理解為假設(shè)現(xiàn)在的情況，所以謂語(yǔ)動(dòng)詞必須為would/should/might+動(dòng)詞原形，學(xué)生在這一點(diǎn)上經(jīng)常會(huì)忽略now的存在，從而按句的形式填寫(xiě)答案。語(yǔ)法四 =情態(tài)動(dòng)詞表猜測(cè)must只用于肯定句/表示很有把握的猜測(cè)/翻譯成“肯定/一定”；can/cou

42、ld用于疑問(wèn)句和否定句；may/might用于肯定句/表示沒(méi)有把握的猜測(cè)/翻譯成“可能也許”mustnt have done 絕對(duì)錯(cuò)/是無(wú)效選項(xiàng)must必須，“不必”用neednt/dont have tomustnt 禁止/不準(zhǔn)一、情態(tài)動(dòng)詞+ do/be表示對(duì)現(xiàn)在行為或動(dòng)作進(jìn)行猜測(cè)Youve been working all day.

43、e/have been表示對(duì)過(guò)去行為或動(dòng)作進(jìn)行猜測(cè)a. must have done表示對(duì)過(guò)去某事的肯定猜測(cè)。其否定或疑問(wèn)形式都用can(could) 來(lái)表示.Since the road is wet, it must have rained last night.He cant have missed the way. I drew him a map.“The dictionary has disappeared. Who could/can have taken it?”b. may / might have donemay / might have done 表示推測(cè)過(guò)去某事“也許”

44、發(fā)生了.I cant find my keys. I may / might have left them at the school yesterday.c. could have done 在肯定句型中, 往往用作委婉的批評(píng).本可以做什么,而沒(méi)做; 有時(shí)也用作猜測(cè).You could have done it better.Tom could have taken the dictionary.d. ought to / should have done和 ought not to / shouldnt have done本該做而事實(shí)上沒(méi)做 本不該做而事實(shí)上做了e. neednt have
