　　英語語法知識難點(diǎn)（一）

　�。ㄒ唬� 形容詞和副詞

　　I． 要點(diǎn)

　　A． 形容詞

　　1、 形容詞的用法

　　形容詞是用來修飾、描繪名詞的，通常在句中作定語、表語或賓補(bǔ)，有時(shí)還可作狀語。如：

　　He is honest and hardworking.

　　I found the book interesting.

　　某些形容詞與定冠詞連用表示一類人作主語時(shí)，謂語通常用復(fù)數(shù)形式。如：

　　The rich and the poor live in different parts of the city.

　　The English like to be with their families.

　　多個(gè)形容詞作定語修飾名詞的順序：

　　冠詞+序數(shù)詞+基數(shù)詞+性質(zhì)狀態(tài)（描述性）+形狀大小+新舊老少+顏色+國籍+材料+名詞。如：

　　the second five interesting big new red Chinese wall papers.

　　2、 形容詞比較等級的形式

　�。�1） 規(guī)則形式

　　一般說來，單音節(jié)詞及少數(shù)雙音節(jié)詞在后加-er; --est 來構(gòu)成比較級和更高級；其他雙音節(jié)詞及多音節(jié)詞在前加more, most.如：

　　great-greater-greatest

　　busy-busier-busiest

　　important-more important-(the)most important

　�。�2） 不規(guī)則形式

　　good (well)-better-best

　　bad (ill)-worse-worst

　　many (much)-more-most

　　little-less-least

　　（3） 形容詞比較等級的用法

　�、俦硎緝烧叩谋容^，用形容詞的比較級+than. 如：

　　He is cleverer than the other boys.

　　This one is more beautiful than that one.

　　②表示兩者以上的比較，用"the +形容詞更高級（+名詞）+of(in) …"如：

　　He is the cleverest boy in his class.

　�、郾硎緝烧呤峭�等程度，用"as +形容詞原級+as". 如：

　　He is as tall as I.

　　I have as many books as you.

　�、� 越… 越…

　　例如：The more I learn, the happier I am.

　　⑤ You can never be too careful. 越小心越好

　　又如：You can never praise the teacher too highly.

　　你怎么贊揚(yáng)這個(gè)老師也不過分。

　�、� I have never spent a more worrying day.

　　那一天是較令我擔(dān)心的一天。

　　I have never had a better dinner.

　　這是我吃過的較好的一頓飯。

　�、� My English is no better than yours.

　　我的英語和你的英語都不怎么樣。

　　B．副詞

　　1、 副詞的種類

　�。�1） 時(shí)間副詞 如：ago, before, already, just, now, early, late, finally, tomorrow等

　�。�2） 地點(diǎn)副詞 如：here, there, near, around, in, out, up, down, back, away, outside等。

　�。�3） 方式副詞 如：carefully, angrily, badly, calmly, loudly, quickly, politely, nervously等。

　　（4） 程度副詞 如：almost, nearly, much, greatly, a bit, a little, hardly, so, very等。

　　2、 副詞比較等級的用法

　　其用法與形容詞相似，只是副詞更高級前可省略定冠詞。如：

　　Of all the boys he sings (the) most beautifully.

　　We must work harder.

　　3、 某些副詞在用法上的區(qū)別

　　（1） already, yet, still

　　already表示某事物已經(jīng)發(fā)生，主要用于肯定句；yet表示期待某事發(fā)生，主要用于否定句和疑問句；still表示某事還在進(jìn)行，主要用于肯定句和疑問句，有時(shí)也可用于否定句。如：

　　We've already watched that film.

　　I haven't finished my homework yet.

　　He still works until late every night.

　�。�2） too, as well, also, either

　　too, as well和 also用于肯定句和疑問句，too和as well多用于口語，一般放在句末，而also多用于書面語，一般放在句中與動(dòng)詞連用。either用于否定句和否定的疑問句，往往放在句末。如：

　　He went there too.

　　He didn't go there either.

　　I like you as well.

　　I also went there.

　　(3) hard, hardly

　　hardly意為"幾乎"與hard在詞義上完全不同。如：

　　I work hard every day.

　　I can hardly remember that.

　　(4) late, lately

　　lately意為"較近、近來"，late意為"晚、遲"。如：

　　He never comes late.

　　Have you been to the museum lately?

　　II． 例題

　　例1 Tom's father thinks he is already ____

　　A high enough B tall enough

　　C enough high C enough tall

　　解析：該題正確答案是B。修飾人高用tall, 而建筑物的高用high,并且enough修飾形容詞要放在形容詞后面。因此該題選B。

　　例2 ____ the worse I seem to be.

　　A When I take more medicine

　　B The more medicine I take

　　C Taking more of the medicine

　　D More medicine taken

　　解析：該題正確答案為B。"the+形容詞比較級+… , the +形容詞比較級+…"意為越…，越…。該句意為：吃的藥越多，我的病越是加重。

　　例3"I haven't been to London yet".

　　A too B also C either D neither

　　解析：該題正確答案為C。A和B都用于肯定句中。D-neither本身意為否定"兩者都不"，而C-either則用于否定句中，意為"也"。

　　例4 Mr Smith was ____ moved at the news.

　　A deep B deeply C very deep D quite deeply

　　解析：該題正確答案為B。A. deep用于副詞時(shí)，修飾具體的深，如dig deep,而B-deeply則修飾表示感情色彩的詞，如該題為deeply moved.另如deeply regret等。而D-quite和deeply均為副詞，不能互相修飾。

　　（二） 介詞

　　I． 要點(diǎn)

　　1、介詞和種類

　�。�1） 簡單介詞，常用的有at, in, on, about, across, before, beside, for , to, without等。

　�。�2） 復(fù)合介詞，如by means of, along with, because of, in front of, instead of等。

　　2、介詞和其他詞類的習(xí)慣搭配關(guān)系

　�。�1） 和動(dòng)詞的搭配，如agree with, ask for, belong to, break away from, care about等。

　�。�2） 和形容詞的搭配，如afraid of, angry with, different from, good at

　�。�3） 和名詞的搭配，如answer to , key to, reason for, cause of, visit to等.

　　3、介詞短語可以有自己的修飾語，這種修飾語通常有right, just, badly, all, well, directly, completely等少數(shù)幾個(gè)副詞。如：

　　He came right after dinner.

　　He lives directly opposite the school.

　　4、 某些介詞的意義與用法舉例

　�。�1） at, on, in（表時(shí)間）

　　表示時(shí)間點(diǎn)用at,如at four o'clock, at midnight等；表示不確定的時(shí)間或短期假日也用at,如at that time, at Christmas等。

　　指長于或短于一天的時(shí)段用in,如in the afternoon, in February, in Summer, in 1999等。

　　（2） between, among（表位置）

　　between僅用于二者之間，但說三者或三者以上中的每兩個(gè)之間的相互關(guān)系時(shí)，也用between, 如

　　I'm sitting between Tom and Alice.

　　The village lies between three hills.

　　among用于三者或三者以上之間。如：

　　He is the best among the students.

　　（3） beside, besides

　　beside意為"在…旁邊"，而besides意為"除…之外"。如：

　　He sat beside me.

　　What do you want besides this?

　�。�4）in the tree, on the tree

　　in the tree 指動(dòng)物或人在樹上，而on the tree 指果實(shí)、樹葉長在樹上

　　II． 例題

　　例1 Do you know any other foreign language____ English?

　　A except B but C beside D besides

　　解析：A、B兩項(xiàng)except等于but，意為"除了…"，C-beside意為"在…旁邊"，不符合題意。而D-besides, 意為"除了…之外，還有"。所以該題正確答案為D。該題意為：除了英語外，你還知道別的語言嗎？

　　例2 He suddenly returned ____ a rainy night.

　　A on B at C in D during

　　解析：我們均知道，at night這一短語，但如果night前有修飾詞，表具體的夜晚，則要用介詞on來修飾，故該題正確答案為A。

　　例3 I'm looking forward ____your letter.

　　A to B in C at D on

　　解析：該題正確答案為A。look forward to 為固定搭配，意為"期望、盼望"。

　�。ㄈ�） 連詞

　　I． 要點(diǎn)

　　1、 連詞的種類

　�。�1） 并列連詞用來連接并列關(guān)系的詞、短語或分句，如and, for, or, both…and, either…or, neither…nor等。

　�。�2） 從屬連詞用來引導(dǎo)從句，如that, if, whether, when, after, as soon as等。

　　除了從屬連詞（引導(dǎo)狀語從句）外，還有其它可以用來引導(dǎo)從句的詞類。它們是連接代詞和連接副詞（引導(dǎo)名詞性從句），關(guān)系代詞和關(guān)系副詞（引導(dǎo)定語從句）。

　�。ㄋ模﹦�(dòng)詞時(shí)態(tài)、語態(tài)

　�。�1） 表示經(jīng)常發(fā)生的動(dòng)作或現(xiàn)在存在的狀態(tài)，常與sometimes, always, often, every day等時(shí)間狀語連用。如：

　　Sometimes, we go swimming after school.

　�。�2） 表示客觀真理、科學(xué)事實(shí)等。如：

　　The earth goes round the sun.

　　2、 現(xiàn)在進(jìn)行時(shí)

　　(1) 表示說話時(shí)或現(xiàn)階段正在進(jìn)行的動(dòng)作，常與now, at present等時(shí)間狀語連用。如：

　　What are you doing now?

　　(2) 和always, continually等連用，表一種經(jīng)常反復(fù)的動(dòng)作，常含有某種情感。如：

　　He is always doing good deeds.

　　3、 現(xiàn)在完成時(shí)

　　主要表示動(dòng)作發(fā)生在過去，對現(xiàn)在仍有影響，或動(dòng)作一直延續(xù)到現(xiàn)在，或可能還要繼續(xù)下去，常與just, already, so far, once, never 等詞連用。如:

　　Have you ever been to Beijing?

　　4、一般將來時(shí)

　　表示將來某一時(shí)間要發(fā)生的動(dòng)作或存在的狀態(tài)，常與tomorrow, next year等連用。如：

　　I'll meet you at the school gate tomorrow morning.

　　We're going to see a film next Monday.

　　5、一般過去時(shí)

　　表示在過去某一時(shí)間或某一階段內(nèi)發(fā)生的動(dòng)作或存在的狀態(tài)，常與yesterday, last year, in 1998, a moment ago等詞連用。如：

　　II．例題

　　例１ I learned that her father ____ in 1950.

　　A had died B died C dead D is dead

　　解析：該題正確答案為Ｂ。從句中的謂語動(dòng)詞動(dòng)作雖然發(fā)生在主句謂語動(dòng)詞的動(dòng)作之前，但因從句中有明確的過去時(shí)間狀語in 1950, 所以不用過去完成時(shí)態(tài)，而用一般過去時(shí)態(tài)。

　　例２ The five-year-old girl ____ by her parents.

　　A is looked B has looked for

　　C is being looked for D has been looked

　　解析：該題正確答案為Ｃ。在帶有介詞的動(dòng)詞短語用于被動(dòng)語態(tài)句中，介詞不能省，否則就變成了不及物動(dòng)詞短語，而不能用于被動(dòng)語態(tài)的句子中。

　　（五）動(dòng)詞虛擬語氣

　　與現(xiàn)在事實(shí)相反

　　動(dòng)詞過去式 （be要用were）

　　should

　　+動(dòng)詞原形

　　would

　　與過去事實(shí)相反

　　３、were to +動(dòng)詞原形

　　should

　　＋動(dòng)詞原形

　　would

　　注：如果條件從句謂語動(dòng)詞包含有were或had, should, could有時(shí)可將if省去, 但要倒裝。如：

　　Had you (If you had) invited us, we would have come to your party.

　　２、 虛擬語氣在各種從句的應(yīng)用

　�。ǎ保� 在主語從句中用來表示驚奇、惋惜、理應(yīng)如此等，其謂語形式是"should(可省) ＋動(dòng)詞原形"，常用于以下三種句型中。

　　句型一：It is necessary (important, natural, strange, etc) that…

　　I suggest that we (should) go swimming.

　�。ǎ常� 在表語從句中，表示間接的命令，要求、請求、建議、決定等，主句中的主語通常是suggestion, proposal, request, orders, idea等。從句謂語形式是"(should)＋動(dòng)詞原形"。如：

　　His suggestion is that we (should) leave at once.

　　（４） 在同位語從句中，謂語形式是"(should)＋動(dòng)詞原形"。如：

　　We received order that the work be done at once.

　�。ǎ担� 在It is time that…句型中，其謂語動(dòng)詞形式是"動(dòng)詞的過去式"或

　　"should ＋動(dòng)詞原形",should不可省。如：

　　It's time (that) we went ( should go) to school.

　　II． 例題

　　例１ We had hoped that he ____ longer.

　　A stays B have stayed C stayed D would stay

　　解析：該題正確答案為Ｄ。had hoped表示"本希望"，同樣用法的動(dòng)詞還有think, expect等，后面的句子需用虛擬語氣

　　例２ "Mary wants to see you today".

　　"I would rather she ____ tomorrow than today."

　　A comes B came C should come D will come

　　解析：該題正確答案為Ｂ。would rather后面的從句需用虛擬語氣，用動(dòng)詞過去時(shí)表示。

　　例３ Had she been older, she ____ it better.

　　A had done B might have done

　　C might do D would do

　　解析：Had she been older = If she had been old. 故該題正確答案為Ｂ。

　�。�六）短語動(dòng)詞

　　（２） 動(dòng)詞＋副詞

　�。ㄆ撸﹦�(dòng)詞不定式

　　I． 要點(diǎn)

　�。�、 不定式的形式。以動(dòng)詞write為例。

　�。病� 不定式的句法功能

　�。ǎ保� 作主語

　　To hear from you is nice.

　　To be a good teacher is not easy.

　　不定式作主語時(shí)，為了保持句子的平衡，往往以it作形式主語，而不定式置于謂語動(dòng)詞后。如：

　　It's nice to hear from you.

　　It's not easy to be a good teacher.

　�。ǎ玻� 作賓語

　　通常用于want, hope, wish, like, need, hate, begin, start, remember, agree, learn, pretend, refuse, manage, help等詞后。如：

　　I forgot to lock the door.

　　Please remember to write to me.

　�。ǎ常� 作表語

　　My job is to pick up letters.

　　He seemed to have heard nothing.

　　（４） 作定語

　　不定式作定語時(shí)，須放在它所修飾的名詞或代詞后。如：

　　I have two letters to write.

　　I have a lot of work to do.

　�。ǎ担� 作賓補(bǔ)

　　通常用于want, wish, ask, order, tell, know, help, advise, allow, cause, force等詞后。如：

　　He ordered her to leave at once.

　　He was forced to obey his order.

　　He got up early to catch the first bus.

　　He worked hard to catch up with the other students.

　�。ǎ罚� 作獨(dú)立成分

　　I cannot decide where to go.

　　（9）不定式的否定式。如：

　　I decided not to go.

　�。�10）不定式的完成式。如：

　　He seemed to have cleaned the room before I came in.

　　The boy is said to have been sent to the hospital last week.

　�。�11）too…to 結(jié)構(gòu)。如：

　　He was too excited to go to sleep.

　　He was only too glad to go. (他太高興了，樂意去)

　�。�12）主動(dòng)表被動(dòng)。如：

　　The book is easy to read.

　　I have a book to read.

　　II．例題

　　例１ I haven't got a chair ____.

　　A to sit B for to sit on C to sit on D for sitting

　　解析：該題選C。不定式to sit on在句中作定語，修飾名詞chair. 因?yàn)椴欢ㄊ胶退�所修飾的名詞間是"動(dòng)賓關(guān)系"，所以不定式必須是及物動(dòng)詞，故此處on不能省略。

　　例2 He was made ____.

　　A go B gone C going D to go

　　解析：該題選D。make sb. do sth. 如果是被動(dòng)形式，不定式do前的to不能省略。

　　例3 A new factory is ____ very soon.

　　A to be built B built

　　C to build D to building

　　解析：該題選A。is to be built意為"將要被建"。

　�。ò耍﹦�(dòng)名詞

　　I． 要點(diǎn)

　　動(dòng)名詞既具有動(dòng)詞的一些特征，又具有名詞的句法功能。

　　I． 要點(diǎn)

　　分詞既具有動(dòng)詞的一些特征，又具有形容和副詞的句法功能。它分為現(xiàn)在分詞和過去分詞兩類�，F(xiàn)在分詞和過去分詞的主要差別在于現(xiàn)在分詞有一般式和完成式，過去分詞則只有一般式�，F(xiàn)在分詞表動(dòng)作正在進(jìn)行，表主動(dòng)。過去分詞及物動(dòng)詞表動(dòng)作已經(jīng)完成，表被動(dòng)。過去分詞不及物動(dòng)詞表動(dòng)作已經(jīng)完成，表主動(dòng)。

　　過去分詞的句法功能：

　　１、 作定語

　　I like to read the novel written by Lu Xun.

　　The woman sitting beside the broken window was a friend of mine.

　　２、 作表語

　　When I came into the room, I found the window was broken.

　　I'm interested in this book.

　�。场� 作賓語補(bǔ)足語

　　I'm going to have my bike repaired.

　　When I walked home, I saw the thief caught by the police.

　　4、作狀語

　　Seen from the top of the mountain, the city looks small.

　　The teacher came into the classroom, followed by his students.

　　現(xiàn)在分詞的句法功能。

　　1、作狀語

　　Seeing from the top of the mountain, I found the city was beautiful.

　　Walking along the street, they suddenly saw him.

　　2、作賓語

　　I hate being spoken ill of.

　　3、作表語

　　Seeing is believing.

　　4、作賓語補(bǔ)足語

　　I noticed him crossing the street.

　　Mother caught him smoking in the kitchen.

　　5、作定語

　　Do you know the man writing a letter?

　　The worker running a machine is my brother.

　　分詞使用中的幾個(gè)問題

　　1、現(xiàn)在分詞的完成式

　　Having cleaned the room, I went out.

　　2、現(xiàn)在分詞的否定式

　　Not having received any letter, he felt a little worried.

　　3、現(xiàn)在分詞與過去分詞的不同

　　現(xiàn)在分詞表示主動(dòng)、正在，過去分詞表示被動(dòng)、完成

　　I found the man killed there.

　　I found the man standing there.

　　4、have結(jié)構(gòu)

　　We have the car repaired.

　　We have repaired the car.

　　We have Tom repair the car.

　　We have Tom repairing the car the whole morning.

　　5、分詞作表語

　　We were excited at the news.

　　The football game is exciting.

　　6、獨(dú)立主格結(jié)構(gòu)

　　初中英語語法重難點(diǎn)集匯

　�。ㄒ唬┲髦^一致

　　主謂一致是指一個(gè)句子的主語和謂語動(dòng)詞保持?jǐn)?shù)的一致關(guān)系。一個(gè)句子中主謂一致，通常指三個(gè)基本原則：語法一致，即形式上一致；概念一致，即概念或意念上的一致；毗鄰一致，即謂語動(dòng)詞的形式與鄰近的名詞一致。

　　一、 語法一致原則

　　1、 在通常情況下，一個(gè)句子的主語和謂語在語法形式上保持一致。即主語為單數(shù)形式，謂語也為單數(shù)形式；主語為復(fù)數(shù)形式，謂語也為復(fù)數(shù)形式。如：

　　This exercise on English idioms is not easy.這個(gè)英語短語訓(xùn)練不容易。

　　2、 在“there be”結(jié)構(gòu)中， “be”的單復(fù)數(shù)取決與后面主語的數(shù).如：

　　There has been little change in this city.這個(gè)城市沒有多少變化。

　　3、“one of”結(jié)構(gòu)，位于用單數(shù)，“two of”結(jié)構(gòu)位于用復(fù)數(shù)

　　One of the things I want to do is traveling.我想做的一件事是去旅行。

　　Two of the boys have lost their way home.有兩個(gè)男孩回家迷路了。

　　3、 倒裝句的主語在謂語之后，避免誤用。

　　Never before has she been to Paris!她以前從未去過巴黎。

　　二、 概念一致

　　1、 主語是抽象概念、短語或從句，謂語用單數(shù)形式。如：

　　To tell lies is wrong.說謊是不正確的。（不定式做主語）

　　Keeping the house is a tiring job.管理家務(wù)是一件很勞累的事。（動(dòng)名詞做主語）

　　How this happened is not clear to anyone.(從句做主語)

　　注意：

　�。�1） 用what或which引導(dǎo)的主語從句或簡單句中的數(shù)的概念取決于后面的表語，因?yàn)樗鼈冊谶壿嬌系囊饬x是相同的。如：

　　Which is your seat?你的座位是哪一個(gè)？

　　Which are your seats?你們的座位是哪些？

　�。�2） 單個(gè)的分詞作主語，不定式作主語，以及主語從句，謂語都用單數(shù)，若用連接上述的相同兩個(gè)成分，謂語才用復(fù)數(shù)。

　　2、 兩個(gè)或兩個(gè)以上的主語用and和both連接時(shí)，謂語用復(fù)數(shù)形式。

　　3、 and連接的并列主語指同一人或同一樣?xùn)|西，and后的名詞前沒有冠詞，謂語用單數(shù)；若有，則用復(fù)數(shù)。如：

　　My best friend and adviser has changed his mind again.我的密友兼顧問又改變他的想法了。

　　My friend and the student Sue are in the classroom.我的朋友和那位叫蘇的同學(xué)在教室里。

　　a. 若and后面加not,謂語用單數(shù)。如：

　　Lilei,and not I, has won the game.是 Lilei贏了比賽，而不是我。

　　b. 用and 連接的單數(shù)主語，前面有each,every,many a,no等詞修飾時(shí)，謂語用單數(shù)。

　　c. 復(fù)數(shù)主語前加each,謂語仍用復(fù)數(shù)。

　　d. no后面名詞為單數(shù)，謂語用單數(shù)；后為復(fù)數(shù)，謂語用復(fù)數(shù)。

　　三、 毗鄰一致

　　由not only…but also,neither…nor…,either…or…,or 連接的并列主語，在肯定句中謂語變化取決于后面的餓主語，在疑問句中取決于前面的主語。如；

　　Either he or I am mistaken.他和我都沒錯(cuò)。

　　Either he or you are to go there.不是他就是你要到那兒去。

　�。ǘ�） 虛擬語氣

　　虛擬語氣表示說話人的愿望、假設(shè)、猜測或建議，而不是事實(shí)。虛擬語氣是通過句中的謂語動(dòng)詞的特殊形式來表現(xiàn)的，因此，掌握虛擬語氣中的各種謂語動(dòng)詞的形式變化，是掌握虛擬語氣的關(guān)鍵。

　　一、 虛擬語氣在簡單句中的用法

　　虛擬語氣用于簡單句中，一般表示祝愿、命令等。謂語動(dòng)詞要用原形。

　　二、 虛擬語氣在主從復(fù)合句中的用法

　�。�1） 在狀語從句中的用法

　　1、 條件句中的用法

　　虛擬語氣的條件句是用謂語動(dòng)詞的特殊形式來表現(xiàn)與現(xiàn)在、過去事實(shí)相反的情況或?qū)�將來發(fā)生的情況表示懷疑，和直陳語氣條件句中的謂語動(dòng)詞形式以及表達(dá)的含義完全不同。虛擬語氣條件句中所用的謂語動(dòng)詞的過去時(shí)、過去完成時(shí)、過去將來時(shí)等，只表示不同的虛擬語氣，和直陳語氣的過去時(shí)、過去完成時(shí)、過去將來時(shí)等毫無關(guān)系。

　　現(xiàn)將虛擬語氣的各種具體形式和用法分述如下；

　　a. 表示與現(xiàn)在事實(shí)相反的情況

　　c. 混合時(shí)間條件句的用法：

　　有時(shí)條件從句的動(dòng)作和主句動(dòng)作發(fā)生的 時(shí)間不一致。這時(shí)動(dòng)詞的形式，應(yīng)根據(jù)它所要表達(dá)的具體時(shí)間來決定用什么形式。

　　1） If she hadn’t trained so hard, she wouldn’t be run so fast.（從句敘述過去，主句敘述現(xiàn)在。）

　　2、 在其他狀語從句中的用法

　　主要用于由as if (as though) 引導(dǎo)的比較狀語從句，從句中謂語動(dòng)詞一般用“動(dòng)詞的過去式（be 變were ）或had +過去分詞。”
