高中英語語法重點(diǎn)難點(diǎn)

1、高中英語語法重點(diǎn)難點(diǎn)回顧主謂一致?？茧y題：1. Five minutes is enough to do this exerciseEach boy and each girl wants to serve the people in futureMore than one student has seen the film. Many a ship has been damaged in the storm.More members than one are against your plan.一些有兩個部分構(gòu)成的名詞表示衣物或工具作主語時, 謂語通常用復(fù)數(shù)形式：glasses, cloth

2、es, trousers, shoes, compasses, chopsticks, scissors等。但如果主語用a kind of , a pair of , a series of等加名詞構(gòu)成時, 謂語動詞一般用單數(shù)形式。A pair of shoes was on the desk并列主語如果指的是同一個人、同一事物或同一概念時, 謂語動詞用單數(shù)形式, 這時and后面的名詞沒有冠詞。例如:Truth and honesty is the best policyThe girls teacher and friend is a young doctorTo love and to b

3、e loved is the great happiness.Going to bed early and getting up early is a good habit.A knife and fork is on the table.當(dāng)主語后面跟有as well as, as much as , no less than, along with, with, like, rather than, together with, but, except, besides, including, in addition to等引導(dǎo)的詞組時, 其謂語動詞的單、復(fù)數(shù)按主語的單、復(fù)數(shù)而定。例如:Th

4、e teacher as well as the students was excitedThe room with its furniture was rented2. A (great) number of修飾可數(shù)復(fù)數(shù)名詞, 謂語動詞用復(fù)數(shù); a great deal of,a large amount of 修飾不可數(shù)名詞, 其短語作主語時, 謂語動詞用單數(shù)。3. 關(guān)系代詞who, that, which等在定語從句中作主語時, 其謂語動詞的數(shù)應(yīng)與句中先行詞的數(shù)一致。例如:Those who want to go please sign your names hereSome of th

6、square old brown wood table6. 某些以a-開首的形容詞例如：afraid，alike，alone，asleep，awake, alive 等只能作表語,不能作定語。某些以-ly結(jié)尾的詞是形容詞而不是副詞：friendly，lively， lovely，lonely，likely，deadly，silly，orderly, timely等。7.bad/ill,badly worse worst little less least表示一方不及另一方時，用“l(fā)ess原級than”的結(jié)構(gòu)表示：This room is less beautiful than that one

7、表示一方超過另一方的程度或數(shù)量時，可在比較級前加表示程度的狀語，如：even，a lot，a bit，a little，still，much，far, yet, by far等修飾：He works even harder than before注意:by far 通常用于強(qiáng)調(diào)最高級。用于比較級時,一般放在比較級的后面, 如放在前面,應(yīng)在二者中間加“the”。He is taller by far than his brother. He is by far the taller of the two brothers.某些以-or結(jié)尾的形容詞進(jìn)行比較時，用to代替than。superior，

8、junior，senior等。He is superior to Mr Wang in mathematics在比較從句中為了避免重復(fù)通常用that(those)，one(ones)代替前面出現(xiàn)的名詞。that指物，one既可指人，也可指物。that可代替可數(shù)名詞單數(shù)和不可數(shù)名詞，而one只能代替可數(shù)名詞。例如：The book on the table is more interesting than that on the deskA box made of iron is stronger than one made of wood8. 表示倍數(shù)的比較級有如下幾種句型:A is thre

10、er (higher, longer, wider) than B.例如:Your school is three times bigger than ours.你們的學(xué)校比我們的學(xué)校大三倍。表示兩倍可以用 twice 或 double。9. 表示“最高程度”的形容詞，如excellent，extreme，perfect等，沒有最高級，也不能用比較級。如果復(fù)數(shù)名詞前有many、few，不可數(shù)名詞前有much、little等表示量的形容詞時，該用so而不用such。如：Ive had so many falls that Im black and blue all over.Mr White g

11、ot so little money a month that he could hardly keep body andsoul together.但little不表示數(shù)量而表示“小”的意思時,仍用such。如:They are such little children that the they cannot clean the house by themselves.10. almost與nearly在very, pretty, not后用nearly, 不用almost。例如：Im not nearly ready.在any, no, none, never前用almost, 不用ne

Yes, you must.注意：neednt have done“表示本來不必做某事而實(shí)際上做了某事”。例如：You neednt have waited for me.“should have done”表示應(yīng)該做到而實(shí)際上沒有做到。You shoul

13、d have started earlier.“ought to have done”表示過去應(yīng)做某事而實(shí)際未做。You ought to have helped him (but you didnt)書報的標(biāo)題,小說等情節(jié)介紹常用一般現(xiàn)在時。表示感覺,愿望和狀態(tài)的某些動詞如have, be, hear, see, like等詞一般不用進(jìn)行時。有些動詞形式上是主動結(jié)構(gòu),但表示被動的意思。常見的有可和 well, easily 等副詞連用的不及物動詞sell,wash,write,read,clean,cook等。例如：The cloth washes well.這布很經(jīng)洗。The new pr

14、oduct sells well.這新產(chǎn)品很暢銷。The pen writes well.這支筆很好寫。在動詞 arrange,command, demand, desire,insist, order,propose, request, require, suggest等后面的賓語從句中用“(should) 動詞原形”(虛擬語氣)例如：We suggested that we (should) have a meeting.We insisted that they (should) go with us.The doctor ordered that she (should) stay i

15、n bed for a few days.He demanded that we (should) start right away.作advice,idea,order,demand,plan,proposal,suggestion,request等名詞的表語從句和同位語從句,其謂語動詞要用虛擬語氣的結(jié)構(gòu)“(should)動詞原形”。例如：We all agreed to his suggestion that we(should) go to Beijing for sightseeing.My idea is that we (should) do exercises first.在fe

16、el, hear, notice, observe, see, watch, have, let, make等詞后的補(bǔ)足語中,不定式不帶to。但是這些句子如果變成被動結(jié)構(gòu)時,就必須帶to。例如：I often hear him sing the song. He is often heard to sing the song.注意：不定式動詞在介詞but, except, besides后面時,如果這些介詞之前有行為動詞do的各種形式,那么,這些介詞后的不定式不帶to,否則要帶to.如：She could do nothing but cry. What do you like to do b

17、esides swim?I have no choice but to go.作定語的不定式如果是不及物動詞,或者不定式所修飾的名詞或代詞是不定式動作的地點(diǎn)、工具等,不定式后面須有相應(yīng)的介詞。例如：He is looking for a room to live in. There is nothing to worry about.Please give me a knife to cut with.There / It is no use/ good/ not any use/ good/ useless doing sth.動詞后可以用動名詞作賓語,但不能用不定式:admit,appre

18、ciate, avoid, consider, delay, enjoy, escape, excuse, feel like, finish, forgive, give up, imagine, include, keep, mention,mind,miss,practise, put off, resist, risk, suggest, cant help, cant stand(無法忍受)等。I tried not to go there.(我設(shè)法不去那里。) I tried doing it again.(我試著又干了一次。)mean to do 有意. mean doing意味

19、著.I mean to come early today.(我打算今天早些來。)Missing the train means waiting for another hour.(誤了這趟火車意味著再等一個小時。)allow, advise, forbid, permitWe dont allow smoking here. We dont allow students to smoke.動詞need,require,want作“需要”解,其后跟動詞作它的賓語時,若表示的含義是被動的,必須用動名詞,或不定式的被動式。例如：The window needs(requires, wants)cle

20、aning(to be cleaned).在短語devote to, look forward to, pay attention to, stick to, be used to, object to,thank you for, excuse me for 等后的動詞也必須用動名詞形式：I look forward to hearing from you soon.Badly polluted, the water cannot be drunk.(原因)Being written in haste, the composition is full of mistakes.(原因,強(qiáng)調(diào)寫的

21、過程,故應(yīng)用現(xiàn)在分詞一般被動式)Having been deserted by his guide, he couldnt find his way through the jungle.(為了強(qiáng)調(diào)已完成的動作)Asked to stay, I couldnt very well refuse.這里 asked 可能意味著 having been asked, 也可能意味著when/since I was asked, 但用了 having been asked 就不會有歧義。下面句中過去分詞表示的時間與謂語動詞所表示的時間相同，所以不能代之以強(qiáng)調(diào)先于謂語動詞的現(xiàn)在分詞完成被動式。例如：Cov

22、ered with confusion, I left the room.我很窘地離開了房間。United, we stand; divided, we fall. 團(tuán)結(jié)則存，分裂則亡。He used to live in London, use(d)nt he /didnt he?There used to be a cinema here before the war, use(d)nt there /didnt there?Such things ought not to be allowed, ought they?He ought to be punished, oughtnt he

23、?但在正式文體中,用ought we not形式。例如:We ought to go, ought we not?或We ought to go ,should we not?含有情態(tài)動詞must的句子表示推則,作“想必”解時,疑問部分不可用mustnt。若前句強(qiáng)調(diào)對現(xiàn)在情況的推測,疑問部分用arent(isnt)十主語,例如：You must be tired,arent you?若陳述部分的must表示“有必要”時,附加疑問句部分則用neednt。例如：You must go home right now, neednt you?當(dāng)mustnt 表示禁止時,附加疑問部分一般用must。如：

24、You mustnt walk on grass, must you?前句謂語動詞是must have過去分詞時,若前句強(qiáng)調(diào)對過去情況的推測(一般有過去時間狀語),疑問部分的謂語動詞用didnt主語;若前句強(qiáng)調(diào)動作的完成,疑問部分的謂語動詞用havent(hasnt)主語, 例如：He must have met her yesterday, didnt he?You must have seen the film, havent you?陳述句謂語部分出現(xiàn)否定詞綴時(前綴或后綴),疑問部分仍用否定結(jié)構(gòu)。例如:He is unfit for his office, isnt he?如果陳述部分

25、包含有no, never, hardly, seldom, few, little,nowhere, nothing等否定或半否定詞時,疑問部分用肯定形式。例如：He is hardly 14 years old,is he?如果陳述部分的主語為everyone,someone,no one等不定代詞,其疑問部分的主語可用he,也可用they。Everyone knows his job, doesnt he? Everyone knows their job,dont they?No one was hurt,were they?Im late, arent I?One cant be to

26、o careful,can one(you)?Have a cup of tea, will you? Lets go there,shall we? Let us go there,will you?同位語從句跟在名詞后面,進(jìn)一步說明該名詞的具體內(nèi)容。引導(dǎo)同位語從句的名詞主要有fact, news, promise, idea, truth等。連接詞用that (不用which)及連接副詞how, when, where, why等。例如：His delay is due to the fact that the car went wrong halfway.The news that ou

27、r team has won the match is true.She asked the reason why there was a delay.關(guān)聯(lián)詞只能用whether不能用if表示“是否”的情況如下:A)在表語從句和同位語從句中。例如：The question is whether the film is worth seeing.The news whether our team has won the match is unknown. B)在主語從句中,只有用it作形式主語時,whether和if都能引導(dǎo)主語從句,否則,也只能用whether。例如：Whether we sh

28、all attend the meeting hasnt been decided yet.It hasnt been decided whether(if)we shall attend the meeting.C)在介詞之后。(介詞往往可以省略)例如：It all depends (on) whether they will support us.D)后面直接跟動詞不定式時。He doesnt know whether to stay or not.E)后面緊接or not 時。We didnt know whether or not she was ready.F)引導(dǎo)讓步狀語從句,只能

29、用whether。Whether you like it or not, you must do it well.G)用if會引起歧義時。例如：Please let me know if you like it.該句有兩個意思：“請告訴我你是否喜歡”?；颉叭绻阆矚g,請告訴我。”用了whether就可以避免。在下面幾種情況下必須用“that”引導(dǎo)定語從句：1)先行詞是不定代詞：all,few,little, much,something,nothing,anything等。All that we have to do is to practise every day.2)先行詞被序數(shù)詞或形容詞

30、最高級所修飾。The first lesson that I learned will never be forgotten.3)先行詞被all,any,every, each, few,little,no,some, 等修飾。I have read all the book (that) you gave me.4)先行詞被 the only, the very, the same, the last 修飾時。He is the only person that I want to talk to.5)先行詞既有人又有物時。They talked of things and persons

31、that they remembered in the school.先行詞是表示地點(diǎn)時,要根據(jù)從句的謂語動詞是及物的還是不及物的。如果是及物的就用that(which),否則用where。This is the house where he lived last year.This is the house that (which) he visited last year.用no soonerthan和hardlywhen引導(dǎo)的從句表示“剛就”。主句中的動詞一般用過去完成時,從句用過去時;而且主句一般倒裝,把助動詞had提到前面。例如：Hardly had I entered the ro

32、om when I heard a loud noise.代詞作主語時,主謂語序不變。Here it is. Here he comes.當(dāng)句首狀語為表示地點(diǎn)的介詞詞組時也常常引起全部倒裝。South of the city lies a big steel factory.From the valley came a frightening sound.表語置于句首時,倒裝結(jié)構(gòu)為“表語+連系動詞+主語”。Present at the meeting were Professor White,Professor Smith and many other guests.Gone are the

33、days when they could do what they liked to the Chinese people.Among the goods are Christmas trees, flowers, candles and toys.He has been to Beijing. So have I.Li Wei cant answer the question. Neither can I.部分倒裝用于省略if的虛擬條件狀語從句。Had you reviewed your lessons,you might have passed the examination.3.用于“形

34、容詞(或名詞、動詞)+as(though)引導(dǎo)的讓步狀語從句中。例如：Pretty as she is ,she is not clever. Try as he would, he might fail again.如果從句的表語是名詞,其名詞前不加任何冠詞。Child as he was, he had to make a living.用于no soonerthan,hardlywhen和not until的句型中。Not until the teacher came did he finish his homework.用于never,hardly,seldom,scarcely, b

35、arely, little,often,at no time,not only,not once等詞開頭的句子。Never shall I do this again. Little did he know who the woman was.6.用于以only開頭的句子(only修飾副詞,介詞短語或狀語從句時)。Only in this way can you master English.Only when he told me did I realize what trouble he was in.如果only后面的詞組不是狀語,則不用倒裝。Only Wang Ling knows t

36、his.定語從句用來說明主句中某一名詞或代詞（有時也可說明整個主句或主句中一部分）而起定語作用的句子叫作定語從句。 一詞引導(dǎo)的定語從句1. 關(guān)系代詞用來指代先行詞是人或物的名詞或代詞 句子成分 用于限制從句或非限制性從句 只用于限制性從句 代替人 代替物 代替人或物主語 Who which that主語 Whom which that賓語 Whose(=of whom) whose(=of which) 例：This is the detective who came from London. 例：The book which I am reading is written by Tomas

37、Hardy. 例：The desk whose leg is broken is very old. 例：This is the room that Shakespeare was born in.關(guān)系代詞的用法 (1) 如果先行詞是all, much, anything, something, nothing, everything, little, none等不定代詞，關(guān)系代詞一般只用that，不用which。例如： All the people that are present burst into tears. (2) 如果先等詞被形容詞最高級以及first, last, any, o

38、nly, few, mush, no, some, very等詞修飾，關(guān)系代詞常用that,不用which, who，或whom。例如： (3) 非限制性定語從句中，不能用關(guān)系代詞that,作賓語用的關(guān)系代詞也不能省略。例如： There are about seven million people taking part in the election, most of whom、are well educated. (4) which還有一種特殊用法，它可以引導(dǎo)從句修飾前面的整個主句，代替主句所表示的整體概念或部分概念。在這種從句中，which可以作主語，也可以作賓語或表語，多數(shù)情況下意思

39、是與and this 相似，并可以指人。例如： He succeeded in the competition, which made his parents very happy. (5) that可指人或物，在從句中作表語，（指人作主語時多用who）僅用于限制性定語從句中。 (6) which可作表語，既可指人，以可指物。指人時，一般指從事某種職業(yè)或是有種特征品性或才能的人。Which引導(dǎo)的定語從句可以限制性的，也可以是非限制性的。 (7) 如果作先作詞的集體名詞著眼于集體的整體，關(guān)系代詞用which;若是指集體中的各個成員，則用who。 (8) 先行詞有兩個，一個指人，一個指物，關(guān)系代詞

40、應(yīng)該用that。例如： The boy and the dog that are in the picture are very lovely. (9) 如果先行詞是anyone, anybody, everyone, everybody, someone, somebody,關(guān)系代詞應(yīng)該用 who 或whom，不用 which。例如： Is there anyone here who will go with you?“介詞關(guān)系代詞“是一個普遍使用的結(jié)構(gòu) (1) “介詞關(guān)系代詞“可以引導(dǎo)限制性定語從句，也可以引導(dǎo)非限制性定語從句?！敖樵~關(guān)系代詞“結(jié)構(gòu)中的介詞可以是 in, on, about

41、, from, for, with, to at, of, without 等，關(guān)系代詞只可用whom或 which,不可用 that 。 (2) from where為“介詞關(guān)系副詞“結(jié)構(gòu)，但也可以引導(dǎo)定語從句。例如： We stood at the top of the hill, from where we can see the town. (3) 像listen to, look at, depend on, pay attention to, take care of等固定短語動詞，在定語從句中一般不宜將介詞與動詞分開。例如： This is the boy whom she ha

42、s taken care of.二關(guān)系副詞引導(dǎo)的定語從句 1關(guān)系副詞也可以引導(dǎo)定語從句 關(guān)系副詞在從句中分別表示時間地點(diǎn)或原因。關(guān)系副詞when在從句中充當(dāng)時間狀語，where 充當(dāng)?shù)攸c(diǎn)狀語，why充當(dāng)原因狀語。 2. that可引導(dǎo)定語從句表示時間地點(diǎn)或原因 That有時可以代替關(guān)系副詞 when, where 或者why引導(dǎo)定語從句表示時間地點(diǎn)或原因，在 that引導(dǎo)的這種定語從句中，that也可以省去。三限制性定語從句與非限制性定語從句 1二者差異比較 限制定語從句緊跟先行詞，同先行詞這間一般不加逗號，僅修飾先行詞，可以由關(guān)系代詞關(guān)系副詞或that來引導(dǎo)。非限制性定語從句僅作補(bǔ)充或說明，

43、用逗號與主句隔開，既可修飾先行詞，又可修飾整個主句，不可用that引導(dǎo)。 2關(guān)系代詞和關(guān)系副詞的選擇依據(jù) (1) 弄清代替先行詞的關(guān)系詞在從句中作什么成分,作狀語的應(yīng)選用關(guān)系副詞，作主語賓語或表語的可選用關(guān)系代詞。 3. 先行詞與定語從句隔離 定語從句一般緊跟在先行詞之后，但定語從句與先行詞之間有時也會插入別的成分，構(gòu)成先行詞與定語從句的隔離。例如： 1) This is the article written by him that Is poke to you about. 2) He was the only person in this country who was invited四

44、As在定語從句中的用法 1. 引導(dǎo)限制性定語從句和非限制性定語從句 （）as多與such 或the same連用，可以代替先行詞是人或物的名詞。 （）as 也可單獨(dú)使用，引導(dǎo)非限制性定語從句，作用相當(dāng)于which。例如：The elephants nose is like a snake, as anybody can see. ）the same that與 the same as在意思上是不同的。 2As引導(dǎo)的非限制性定語從句的位置 as引導(dǎo)的非限制性定語從句位置較靈活，可以位于主句前面中間或后面，一般用逗號與主句隔開，但which所引導(dǎo)的非限制性定語從句只能放在主句之后。例如： (1)

45、As is expected, the England team won the football match. (2) The earth runs around the sun, as is known by everyone.冠詞用法不用愁，巧記兩段順口溜 有些同學(xué)總感到冠詞難用，尤其是不知或拿不準(zhǔn)什么時候要“加冠”，什么時候“免冠”。這里著重介紹一下有關(guān)“定冠詞的用法”和“不定冠詞的幾種情況”的兩段口訣：一、定冠詞的用法。特指雙熟悉，上文已提及；世上獨(dú)無二，序數(shù)最高級；某些專有名，習(xí)語及樂器。以上口訣歸納了用定冠詞的一般情況，即：特指某些人或物談話雙方都熟悉的人或事上文已經(jīng)提到的人或事

46、世界上獨(dú)一無二的事物前序數(shù)詞回形容詞最高級前某些專有名詞前一些習(xí)慣短語（如：in the day等）中和樂器前（如：play the violin / piano）。二、不用冠詞的集中情況。 下列情況應(yīng)免冠，代詞限定名詞前； 專有名詞不可數(shù)，學(xué)科球類三餐飯； 復(fù)數(shù)名詞表泛指，兩節(jié)星期月份前； 顏色語種和國名，稱呼習(xí)語及頭銜。 以上口訣主要概括了一般應(yīng)“免冠”的幾種情況，即： 名詞前已有作定語用的this、that、some、any、my等限定詞。 專有名詞和不可數(shù)名詞前。 表示學(xué)科的（如：maths、Chinese、physics）名詞前。 球類活動的名詞前及三餐總稱前。 復(fù)數(shù)名詞表示泛指（一

47、類人或事）時。 節(jié)日、季節(jié)、星期、月份前。 表示顏色（如：Its red / yellow.）、語種（如：speak English/Japanese）和國家的非全稱名詞（如：We live in China. They come from America.）。 在稱呼或表示頭銜的名詞前。 某些習(xí)慣短語中（如：in bed、go to school等）。情態(tài)動詞的推測性用法 1.Possibility(may/might/can/could) a.在疑問句中表示“可能”，須用can而不用may. b.在肯定陳述句中，用can表示“可能”與用may往往產(chǎn)生含義上的微妙差別：用表示“可能”往往指邏

48、輯上的；用表事實(shí)上的。 Mr Reed is in poor health. He can be ill at any time. Mr Reed looks pale.He may be ill. c.用can表“可能”，較多地用于否定句和疑問句，could不受此限。 If you dont have a guide, you could lose your way. It cnat/couldnt be true. Can/Could the news be true? d.表過去的“可能”可用“may/might+不定式完成體或不定完成進(jìn)行體”，也可用“can/could+不定式完成體”

49、。 She may/might have been expressing her true feelings at that moment. She cant/couldnt have missed the train. e.用“might/could+不定式完成體”有式可以表本來可能發(fā)生但沒有發(fā)生，或本來可能完成卻沒有完成的動作。 You might have killed yourself. I could have reported you.使用半倒裝的幾種情況 1 當(dāng)句首狀語為否定詞或帶有否定意義的詞語時 Never have I found him in such a good mo

50、od. No longer these days is it necessaryfor women to wear veils. Visit our stores. Nowhere else will you find such manificent bargains. 2 當(dāng)句首狀語由only+副詞/介詞詞組/狀語分句時 Only yesterday did he find out that his watch was missing. Only through sheer luck did he manage to get some tickets. Only because there

51、were some cancelled bookings did he get some tickets in the end. 以關(guān)聯(lián)詞not only(but also)開頭的句子或成分 Not only did he complain about the food, he also refused to pay for it. 3 以關(guān)聯(lián)連詞so(that)開頭的句子，在這種結(jié)構(gòu)中，so+a是主語補(bǔ)語的前置；so+ad.是狀語的前置 So small was the mark that I could hardly see it. So quickly did theworkmen fi

52、nish their work that they were given a bonus. 4 當(dāng)方式狀語、頻度狀語移至句首 Gladly would I pay more if I couild get better servece by doing so. Many a time has Mike given me good advice.定語從句學(xué)習(xí)容易出錯的幾方面 1、在定語從句中加了多余的或缺少賓語成分。 Some of the boys I invited the didnt come. She told the wrongs had been done to her by the

53、 boss. 2、 把定語從句的主謂一致問題。 Those who has finished may go now. 3、 當(dāng)先行詞為表示時間、地點(diǎn)的名詞時，分不清關(guān)系詞在定語從句中所作的句子成分。 Is this the school where Mr.White visited last month? 4、 分不清限制性定語從句和非限制性定語從句。 The naughty boy often knocked at the Wangs door, that made the family unhappy. 5、與強(qiáng)調(diào)句混淆。 It was in the afternoon when I saw him in the park. 應(yīng)該為： It was in that afternoon that I saw him in the park. 6、 忽視只能用that，不能用which的情況。 We should do all which is useful to the
