高中英語(yǔ)語(yǔ)法知識(shí)點(diǎn)歸納
高中英語(yǔ)語(yǔ)法知識(shí)點(diǎn)梳理
高中英語(yǔ)語(yǔ)法知識(shí)點(diǎn)匯總
高中英語(yǔ)語(yǔ)法知識(shí)點(diǎn)總結(jié)
高中英語(yǔ)語(yǔ)法知識(shí)點(diǎn)
簡(jiǎn)單句、并列句、復(fù)合句
1. 簡(jiǎn)單句
句型：主語(yǔ)+謂語(yǔ)
只包含一個(gè)主謂結(jié)構(gòu)，而句子的各個(gè)結(jié)構(gòu)都只由單詞或短語(yǔ)表示。
2. 并列句
句型： 簡(jiǎn)單句+并列連詞(或連接副詞)+簡(jiǎn)單句
由兩個(gè)或兩個(gè)以上的簡(jiǎn)單句并列連接起來(lái)的句子叫并列句。并列句中的各簡(jiǎn)單句意義同等重要，相互之間沒(méi)有從屬關(guān)系，是平行并列的關(guān)系。它們之間用連詞連結(jié)。
1、聯(lián)合關(guān)系：
常用的連詞有and, not only…but(also), neither…nor等。
Eg. Tom doesn’t smoke, nor does his brother.
2、轉(zhuǎn)折關(guān)系
常用的連詞有but, yet, still, however, while(而，然而)，when(那時(shí)，然后)等。
Eg. He got up very early, (and) yet he failed to catch the morning train.
We played outside till sunset, when it began to rain.
She is tired, (but) still she will make another test.
yet 和still是連接副詞，又叫半連接句。
however(然而，不過(guò)，但是)意義接近yet,可放在句首、句末或插入句子中間。
3、選擇關(guān)系：
常用的連詞有or(或者，還是，否則)，otherwise, or else, either…or等。
Eg. Hurry up, or we’ll be late for school.
4、因果關(guān)系
連詞有：for, so, thus, therefore, and so 等。
Eg. He studied hard, thus he succeeded in passing the exam.
The Frenchman coughed loudly, so he decided to go and get some medicine for it.
for 表示附加或推斷的理由、原因。 Therefore較so更正式，and so 較口語(yǔ)化。
3. 復(fù)合句
句型：主句+連詞+從句;或連詞+從句+主句(包含一個(gè)主句、一個(gè)或一個(gè)以上的從句，或只包含一個(gè)從句，但有兩個(gè)或兩個(gè)以上的主句的句子叫復(fù)合句。)
高中英語(yǔ)語(yǔ)法知識(shí)點(diǎn)歸納
動(dòng)詞時(shí)態(tài)，被動(dòng)語(yǔ)態(tài)
一、一般現(xiàn)在時(shí)
1.一般現(xiàn)在時(shí)表示經(jīng)常發(fā)生、習(xí)慣性動(dòng)作、客觀真理、科學(xué)事實(shí)、格言，目前的特征、狀態(tài)、能力等。
2.主句是一般將來(lái)時(shí),時(shí)間、條件狀語(yǔ)從句中用一般現(xiàn)在時(shí)表示將來(lái)。如：
I’ll go there after I finish my work./ If it rains tomorrow, I won’t go there.
3.在以here, there開(kāi)頭的句子里，go, come等少數(shù)動(dòng)詞的一般在時(shí)表示正在發(fā)生的動(dòng)作。
例如：There goes the bell.鈴響了。There comes the bus.汽車來(lái)了。Here she comes.她來(lái)了。
二、現(xiàn)在進(jìn)行時(shí)
1.表示正在進(jìn)行的動(dòng)作。
2.表示按計(jì)劃安排即將發(fā)生的動(dòng)作。
例如：She is leaving for Beijing.她要去北京。
He is working as a teacher tomorrow.從明天起他要做老師。
My father is coming to see me this Saturday.這個(gè)星期六我爸爸要來(lái)看我。
3.代替一般現(xiàn)在時(shí)，描繪更加生動(dòng)。
例如:The Changjiang River is flowing into the east.江水滾滾向東流。The sun is rising in the east.太陽(yáng)從東方冉冉升起。
4.大多數(shù)動(dòng)詞可用于進(jìn)行時(shí)，但也有些動(dòng)詞不用于進(jìn)行時(shí)。常見(jiàn)的有：exist, live, understand, mean, owe, belong to, know, doubt, suppose, remember, forget,
believe,trust,want,wish,refuse,like,hate,dislike,prefer,mind,hope等。
三、現(xiàn)在完成時(shí)

例如：I have finished the report./ She has cleaned the room.
2.表示從過(guò)去開(kāi)始，待續(xù)到現(xiàn)在的動(dòng)作或狀態(tài)，往往和“for…”, “since…”表述的一段時(shí)間狀語(yǔ)連用。例如：He has learned English for six years./ They have worked here since they left college.
3.現(xiàn)在完成時(shí)與一般過(guò)去時(shí)的區(qū)別：
1)用兩種時(shí)態(tài)來(lái)表述發(fā)生在過(guò)去的某一動(dòng)作，現(xiàn)在完成時(shí)強(qiáng)調(diào)這一過(guò)去動(dòng)作對(duì)現(xiàn)在產(chǎn)生的影響或結(jié)果，而一般過(guò)去時(shí)只表達(dá)過(guò)去的動(dòng)作或狀態(tài)，和現(xiàn)在關(guān)系不大。例如：She has cleaned the room. It’s very clean now.(此句has cleaned就不能改為cleaned.一是因?yàn)閏leaned與現(xiàn)狀無(wú)關(guān)，二是因?yàn)橐话氵^(guò)去時(shí)不可突然跳到It’s…這樣的一般現(xiàn)在時(shí)。)
2)漢語(yǔ)中的“了”、“過(guò)”、“曾”等詞常用完成表達(dá)，如：I have seen that film.(我看過(guò)那部電影了。)但是如果是在特定的過(guò)去時(shí)間“看了”、“做過(guò)”，就不可用完成時(shí)而必須用一般過(guò)去進(jìn)來(lái)表達(dá)。例如：When did you see that film?

5.短暫動(dòng)詞(即瞬間動(dòng)詞)，join, lose, buy, borrow, leave, go, come, arrive, die, marry, finish, complete, begin, start, break out等，在完成時(shí)態(tài)中，其肯定式不能和表示一段時(shí)間的狀語(yǔ)連用。例如不能說(shuō)：He has finished the work for three hours.要翻譯“他已完成工作三小時(shí)了?！笨刹捎?)“ago法”：He finished the work three hours ago.2)“延續(xù)法”：He has been through(with)the work for three hours.3)“since法”：It is/has been three hours since he finished the work.
四、現(xiàn)在完成進(jìn)行時(shí)
1.用來(lái)表示從過(guò)去某一時(shí)刻開(kāi)始一直持續(xù)到現(xiàn)在(或今后還要繼續(xù)一去)的動(dòng)作。例如：He has been doing the maths problems since 8:00./ It has been raining for two days.
2.凡是不能用于現(xiàn)在進(jìn)行時(shí)的動(dòng)詞均不能用于現(xiàn)成完成進(jìn)行時(shí)。

六、過(guò)去進(jìn)行時(shí)
1.表示過(guò)去某一時(shí)刻或某一段時(shí)間內(nèi)正在進(jìn)行的動(dòng)作(這一過(guò)去時(shí)間須用時(shí)間狀語(yǔ)表示)。例如：He was preparing his lecture all day yesterday.
2.表示動(dòng)作在另一過(guò)去動(dòng)作發(fā)生時(shí)進(jìn)行。例如：They were still working when I left.

高中英語(yǔ)語(yǔ)法知識(shí)點(diǎn)梳理
被動(dòng)語(yǔ)態(tài)
一、被動(dòng)語(yǔ)態(tài)的句型
1.常見(jiàn)句式是：主語(yǔ)(受動(dòng)者)+be+過(guò)去分詞+(by+施動(dòng)者)
例如：He was scolded by the English teacher.
2.主語(yǔ)+get+過(guò)去分詞+其它成分
例如：The boy got drowned last summer./ She got fired because of her faults.
注意：使用這種結(jié)構(gòu)不能帶有“by+施動(dòng)者”
3.帶有雙賓語(yǔ)(直接賓語(yǔ)和間接賓語(yǔ))的主動(dòng)句變?yōu)閯?dòng)句，其主語(yǔ)可以是直接賓語(yǔ)，也可以是間接賓語(yǔ)。
例如：?She lent me a bike.
被動(dòng)：1)I was lent a bike(by her). 2)A bike was lent to me(by her).
4.情態(tài)動(dòng)詞+be+過(guò)去分詞
例如：This problem must be worked out in half an hour.
5.雙重被動(dòng)式：主語(yǔ)+被動(dòng)式謂語(yǔ)+不定式的被動(dòng)式+其它成分
例如;These magazines are not allowed to be taken out of the reading-room./The murderer was ordered to be shot.
二、主動(dòng)表示被動(dòng)的幾種情況
1.不及物動(dòng)詞與狀語(yǔ)連用，用以表示主語(yǔ)的品質(zhì)和狀態(tài)。常見(jiàn)動(dòng)詞是：cut, sell, read, write, fill, cook, lock, wash, drive, keep等。例如：This knife cuts well.這把刀好切。These books sell well.這些書(shū)好賣。The pen writes smoothly.這支筆寫(xiě)起來(lái)流暢。Meat won’t keep long in such hot weather.肉在這樣熱的天氣里放不長(zhǎng)久。The cloth washes well.這種布好洗。
2.一些連系動(dòng)詞的主動(dòng)式+形容詞。常見(jiàn)動(dòng)look, smell, taste, sound, feel, prove, turn out等。
例如：The apples taste good./The flower smells wonderful./The news proved/turned out true./Cotton feels soft.
注：prove也可用于被動(dòng)式，如：His answer(was) proved right.
3.不定式在某些形容詞之后，且與主語(yǔ)有動(dòng)賓關(guān)系。常見(jiàn)形容詞有：hard, difficult, easy, heavy, fit, good, comfortable, convenient, impossible等。例如：The problem is easy to do./The question is difficult to answer./The box is heavy to carry./The project is impossible to complete in a year.比較：The problem is to be done./The question is to be answered.沒(méi)有形容詞時(shí)，雖然不定式與主語(yǔ)是動(dòng)賓關(guān)系，但必須用被動(dòng)式。
三、容易誤用被動(dòng)語(yǔ)態(tài)的幾種情況：
1.I teach myself French.不可變?yōu)镸yself is taught French.因?yàn)榉瓷泶~不可作主語(yǔ)。
2.We help each other/one another.不可變?yōu)镋ach other/One another is helped by us.因?yàn)橄嗷ゴ~不可作主語(yǔ)。
3.He lost heart.不可變?yōu)镠eart was lost by him.因?yàn)橄髄ose heart, make a face, keep silence, lose in thought這類動(dòng)賓結(jié)構(gòu)的固定短語(yǔ)只能用于主動(dòng)式，不能用被動(dòng)式。
4.She took part in the sports meet.不能變?yōu)門he sports meet was taken part in by her.因?yàn)橄髏ake part in, belong to ,own, have, hate, fail, contain等表狀態(tài)動(dòng)詞沒(méi)有被動(dòng)語(yǔ)態(tài)。
高中英語(yǔ)語(yǔ)法知識(shí)點(diǎn)匯總
主謂一致Agreement
在英語(yǔ)的句子中，謂語(yǔ)動(dòng)詞的形式應(yīng)與主語(yǔ)的人稱和數(shù)保持一致。如何判定，則要看句子的意思。多數(shù)情況下，根據(jù)句子的主語(yǔ)形式就能判定，但有的則要看整句的意思，及強(qiáng)調(diào)的內(nèi)容。下面我們就常用的、易混的幾種情況作一下解釋。
1、以單數(shù)名詞或代詞、不定式、動(dòng)名詞短語(yǔ)或從句作主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞要用單數(shù)形式。如：

1)Jane, Mary and I are good friends.
2)He and my father work in the same factory.
3)His sister, no less than you, is wrong.
4)The father, rather than the brothers, is responsible for the accident.

9、關(guān)系代詞who, that, which等在定語(yǔ)從句中作主語(yǔ)時(shí)，其謂語(yǔ)動(dòng)詞的數(shù)應(yīng)與句中先行詞的數(shù)一致。如：
1)Those who want to go please sign their names here.
2)Anyone who is against this opinion may speak out.
3)He is one of the students who were praised at the meeting.
10、表示時(shí)間、距離、價(jià)格、度量衡等的復(fù)數(shù)名詞或短語(yǔ)作為一個(gè)整體看待時(shí)，其謂語(yǔ)動(dòng)詞常用單數(shù)形式。
11、復(fù)數(shù)形式的專有名詞作為整體看待(如人名、地點(diǎn)、國(guó)家、組織、書(shū)籍、報(bào)刊等)，動(dòng)詞用單數(shù)形式。如：

1)All of the apple is rotten. 整個(gè)蘋(píng)果都爛了。
2)All of the apples are rotten. 所有的蘋(píng)果都爛了。

高中英語(yǔ)語(yǔ)法知識(shí)點(diǎn)總結(jié)
復(fù)合句
( 1 ) 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。
II. That與which, who, whom的用法區(qū)別
III. As與which的區(qū)別
IV. 限制性定語(yǔ)從句與非限制性定語(yǔ)從句的區(qū)別
( 2 )狀語(yǔ)從句
狀語(yǔ)從句在主從復(fù)合句中修飾主句中的動(dòng)詞、形容詞或副詞等，按意義可分為地點(diǎn)、原因、目的、結(jié)果、條件、方式、比較等。
1、時(shí)間狀語(yǔ)從句
由從屬連詞when, whenever, as, while, before, since, once, till. Eg. I waited till he had finished his work.
A. when, as, while 作時(shí)間從屬連詞的區(qū)別。
When可引導(dǎo)持續(xù)性動(dòng)作，又可引導(dǎo)短暫性動(dòng)作。它可表示主從句的動(dòng)作同時(shí)發(fā)生，或從句的動(dòng)作發(fā)生在主句動(dòng)作之前。 Eg. When I was a boy, I used to go to the seashore on Sundays. (同時(shí))
B. as 引導(dǎo)持續(xù)性動(dòng)作，側(cè)重表示主句和從句動(dòng)作同時(shí)發(fā)生。 Eg. He hurried home, looking behind as he went.
C. while “在某一段時(shí)間里”、“在……期間”
While引導(dǎo)的動(dòng)作必須是持續(xù)性的，它也強(qiáng)調(diào)主句和從句動(dòng)作的同時(shí)發(fā)生，往往側(cè)重主句和從句動(dòng)作的對(duì)比。
Eg. Please don’t talk so loud while others are working.
當(dāng)when, as, while(正當(dāng)……的時(shí)候)表示主句和從句的動(dòng)作同時(shí)發(fā)生時(shí)，可以換用。
當(dāng)when引導(dǎo)的狀語(yǔ)從句是系表結(jié)構(gòu)(名詞作表語(yǔ))，其主語(yǔ)又和主句主語(yǔ)一致時(shí)，往往可用as引導(dǎo)的省略從句代替，應(yīng)注意as在這里是連詞，不是介詞，后邊名詞與年齡有關(guān)。
Eg. As a young man(=when he was a young man)he was a postmaster.
D. before 如果when和before引導(dǎo)的句子位于主句之后，有時(shí)要譯為“才”、“這時(shí)”等。
Eg. He almost knocked me down before he saw me. I was having lunch when someone knocked at the door.
E. by the time, each time, every time, immediately, the moment, soon after, shortly after等也可以作為連詞，引導(dǎo)時(shí)間狀語(yǔ)從句。Eg. Each time he came to Beijing on business, he would call on me. I recognized you the moment I saw you.
F. 時(shí)間狀語(yǔ)從句中的謂語(yǔ)動(dòng)詞一般不能用任何一種將來(lái)時(shí),只能用現(xiàn)在時(shí)或過(guò)去時(shí)態(tài)表示將來(lái)時(shí)。
E. hardly…when; no sooner ...than=as soon as
這兩個(gè)句組只能用于過(guò)去時(shí)，即從句謂語(yǔ)動(dòng)詞用一般過(guò)去時(shí)，主句謂語(yǔ)動(dòng)詞用過(guò)去完成時(shí)。Hardly、no nooner放在句首時(shí)，主句主謂倒裝。
Eg. He had hardly fallen asleep when he felt a soft touch on his shoulder.
Hardly had he fallen asleep when he felt a soft touch on his shoulder.
Eg. I had no sooner come home than it began to rain. No sooner had I come home than it began to rain.
2、 地點(diǎn)狀語(yǔ)從句：where, wherever引導(dǎo)
Eg. Go back where you came from. Where there is water, there is life.
3、原因狀語(yǔ)從句
由連詞because, as, since, now than (既然，由于)
because引導(dǎo)的從句是全句意思的重心所在。在有上下文的情況下，可以不要主句而單獨(dú)成句。as與since則不能。
在回答why開(kāi)始的問(wèn)句時(shí)只能用because。
在強(qiáng)調(diào)句式中強(qiáng)調(diào)原因狀語(yǔ)從句，只能用because引導(dǎo)從句，不能用as或since.
Eg. It was because he was ill that he didn’t go with us.
as (由于)所引導(dǎo)的從句一般放在主句之前，說(shuō)明原因;后邊的主句說(shuō)明結(jié)果。主句和從句表達(dá)的內(nèi)容同等重要。 Eg. As there was no answer, I wrote again.
以as引導(dǎo)的從句位于主句之后時(shí)，它的力量更弱一些，類似一種附帶的說(shuō)明。As在口語(yǔ)中使用較多。
since(既然，因?yàn)?：用以表示顯然的或已知的理由、原因。從句的意思是次要的，主句是全句意思的重心所在。
Eg. Since he can not answer the question, you’d better ask someone else.
now that與since, as 同義。其區(qū)別是now that用來(lái)說(shuō)明一種新情況，然后再加以推論，從句與主句的因果關(guān)系很小，而since和as連接的句子因果關(guān)系比較明顯。
Eg. Now that you have finished the work, you are free to do what you like.
注意：用了以上表示原因的從屬連詞，主句不可再用并列連詞so.
并列連詞for有時(shí)表示因果關(guān)系，有時(shí)是對(duì)前面分句的內(nèi)容加以解釋或推斷。
當(dāng)for表示因果關(guān)系時(shí)，可和從屬連詞because同樣使用，但語(yǔ)氣較弱。
Eg. He could not have seen me, for (or: because) I was not there.
4、目的狀語(yǔ)從句
that, so that, in order that, for fear that(以免，唯恐)，lest(唯恐，免得)：lest從句中謂語(yǔ)(should)+v, in case (萬(wàn)一)等。
Eg. We remained at home lest(=for fear that) they should come in our absence.
目的狀語(yǔ)從句的消語(yǔ)常含有may(might),can, could, should, will等情態(tài)動(dòng)詞。通常主句在前，從句在后，主句與從句之間沒(méi)有逗號(hào)。
lest 只用于正式文體，在現(xiàn)代英語(yǔ)中多以for fear that, so that…not等代替。
5、結(jié)果狀語(yǔ)從句
由連詞that, so that, so…that , such…that etc.
注意區(qū)別that, so that引導(dǎo)的目的狀語(yǔ)從句和結(jié)果狀語(yǔ)從句。根據(jù)上下文來(lái)判斷，從句之前有逗號(hào)的常是結(jié)果狀語(yǔ)從句;從句中有情態(tài)動(dòng)詞的多半是目的狀語(yǔ)從句。
Eg. She hurried, so that she caught the bus. (結(jié)果) She hurried so that she might catch the bus.(目的)
6、條件狀語(yǔ)從句
通常由if, unless(除非)，as long as, so long as只要，in case (that)萬(wàn)一
unless 從句的謂語(yǔ)只能用肯定式
主將從現(xiàn)
7、方式狀語(yǔ)從句
連詞as, as if(as though)等引導(dǎo)從句多用虛擬語(yǔ)氣。 Eg. He walked as if he were drunk.
8、比較狀語(yǔ)從句
as…as, not so (as)…as, than等引導(dǎo) eg. Peter swims as well as Tom does.
the +比較級(jí)(從句)，the+比較級(jí)(主句) eg. The harder we work, the happier we feel.
9、讓步狀語(yǔ)從句
though, although, as(雖然)，even if, even though, whoever, whatever, whichever, whenever, however, no matter who (what, which, etc)
eg. Wherever you work, you can always find time to study.
Whether he comes or not, we’ll discuss the problem this afternoon.
讓步狀語(yǔ)從句可放在句首、句中、句尾
though與although同義。Although 較為正式，多置于句首，as引導(dǎo)的讓步狀語(yǔ)從句多用于書(shū)面語(yǔ)。它比用though(although)引導(dǎo)的讓步狀語(yǔ)從句更有表現(xiàn)力，語(yǔ)氣更強(qiáng)。As引導(dǎo)的讓步狀語(yǔ)從句要使語(yǔ)序部分倒裝。
Eg. Child as he was, he had to help support the family.
even if (though)從句所說(shuō)的不一定是事實(shí)。 Though從句一般說(shuō)的是事實(shí)。
whether一般引導(dǎo)名詞性從句。當(dāng)引導(dǎo)讓步狀語(yǔ)從句時(shí)，必須有逗號(hào)和主句分開(kāi)，而且其前邊可加no matter.
Eg. You’ll have to do it, (no matter) whether you like it or not.
讓步狀語(yǔ)從句和主句之間不可再用but等純并列連詞，但可用yet, still, nevertheless等副詞來(lái)加強(qiáng)語(yǔ)氣。
Eg. Though he was tired, yet (still, nevertheless) he went on working.
不可將no matter與“疑問(wèn)詞+ever”連用。
Eg. Whatever (no matter what )you say, I won’t agree you .
No matter whatever you say, I won’t agree with you .(錯(cuò))
