㈠ 高中英语语法大全
高中英语语法
组成句子的各个部分叫句子成分。英语句子成分有主语,谓语,表语,宾语,宾语补足语,定语,状语等。
顺序一般是主语,谓语,宾语,宾语补足语,而表语,定语,状语的位置要根据情况而定。
1、主语
主语表示句子主要说明的人或事物,一般由名词,代词,数词,不定式等充当。
Helikeswatch'ingTV.他喜欢看电视。
2、谓语
谓语说明主语的动作,状态或特征。
1),简单谓语
由动词(或短语动词)构成。
可以有不同的时态,语态和语气。
Westud'yforthepeo'ple.我们为人民学习。
2),复合谓语:情态动词+不定式
Icanspeakalit'tleEng'lish.我可以说一点英语。
3、表语
表语是谓语的一部分,它位于系动词如be之后,说明主语身份,特征,属性或状态。一般由名词,代词,形容词,副词,不定式,介词短语等充当。
Mysis'terisanurse.我姐姐是护士。
4、宾语
宾语表示动作行为的对象,跟在及物动词之后,能作宾语的有名词,代词,数词,动词不定式等。
WelikeEng'lish.我们喜欢英语。
有些及物动词可以带两个宾语,往往一个指人,一个指物,指人的叫间接宾语,指物的叫直接宾语。
Hegavemesom'eink.他给了我一点墨水。
有些及物动词的宾语后面还需要有一个补足语,意思才完整,宾语和它的补足语构成复合宾语。如:
Wemakehimourmon'itor.我们选他当班长。
5、定语
在句中修饰名词或代词的成分叫定语。
用作定语的主要是形容词,代词,数词,名词,副词,动词不定式,介词短语等。形容词,代词,数词,名词等作定语时,通常放在被修饰的词前面。
Heisanewstu'dent.他是个新生。
但副词,动词不定式,介词短语等作定语时,则放在被修饰的词之后。
Thebikeintheroomismine.房间里的自行车是我的。
6、状语
修饰动词,形容词,副词以及全句的句子成分,叫做状语。用作状语的通常是副词,介词短语,不定式和从句等。状语一般放在被修饰的词之后或放在句尾。副词作状语时可放在被修饰的词前或句首。
HelivesinLon'don.他住在伦敦。
7.补语用来说明宾语或主语所处的状态或正在进行的动作,因为英语中有些动词加宾语后意思仍然不完整,如:make(使...),ask(请)等等。如果我们说:我们使我们的祖国。这不是一句完整的话。应该说:我们使我们的祖国更美丽。这是的“美丽的(beautiful)”为形容词做补语,说明祖国的状态。英语句子为:We will make our country more beautiful.作补语的词或词组为:形容词,副词,名词,不定式,ing形式,数词等。
句子的类型:
1.主语+谓语
2.主语+谓语+状语
3.主语+谓语+宾语
4.主语+系动词+表语
5.主语+谓语+间接宾语+直接宾语
6.主语+谓语+直接宾语+间接宾语
7.主语+谓语+宾语+宾语补足语

4. -ing分词的语法作用
-ing分词一方面具有动词的性质,另一方面也相当于一个名词或形容词、副词,在句中可以作主语、表语、宾语、定语、状语和补语等。
1)–ing分词(短语)作主语:
Laying eggs is the ant queen''s full-time job. 产卵是蚁后的专职工作。
Saying is easier than doing. 说比做容易。
在下面两种结构中,-ing分词也作主语。
①为了保持句子平衡,通常用作形式主语,而把真实主语放在句末。如:

注:-ing分词作状语时,它的逻辑主语就是整个句子的主语。

5. -ing分词的复合结构:
-ing分词的复合结构通常由物主代词、 人称代词宾格、 名词所有格或者名词的普通格+-ing分词构成, 在句子开头时必须用物主代词和名词所有格,通常在句中作主语和宾语。如:
His coming made us very happy. 他的到来使我们大家都很高。
He was awakened by someone’s knocking at the door. 他被某人的敲门声吵醒了。
1. –ing分词作主语和表语时与不定式的区别:
-ing分词和动词不定式作主语和表语的主要区别在于:在表示比较抽象的一般的多次性行为时多用 -ing分词;在表示具体的或一次性的动作,特别是将来的动作时,多用不定式。如:
Smoking is forbidden here. (泛指吸烟)这里禁止吸烟。
It’s not good for you to smoke so much. (指你吸烟)吸这么多烟对你的身体不好。
My job is teaching. 我的工作是教书。

3. 有些动词既能接不定式,又能接-ing分词,含义有所不同。如:
①forget, remember, regret等词后面接不定式表示不定式动作后于谓语动作,而后接-ing分词作 宾语表示分词动作先于谓语动作。如:
Do you remember seeing me before? 你记得以前见过我吗?
Remember to lock the door when you leave. 离开时要记得锁门。
②动词mean, stop, try, go on等动词后面接分词和接不定式作宾语,意思也有所不同。如:
I try not to think about that. 我尽量不去想那件事。
Would you please try doing that again? 请你再试一次好吗?
I mean to change it for another one. 我想换成另外一个。
Missing the train means waiting for another hour. 误了这班车就意味着再等一个小时。

注意:有时人们把stop后的动词不定式理解为目的状语。
③动词allow, advise, forbid, permit等可直接跟-ing分词作宾语,不可以接动词不定式作宾语, 但可接不定式作宾语补语。如:
Please permit me to say a few words. 请允许我说几句话。
We don’t permit smoking here. 我们这儿不允许吸烟。
④动词need, require, want作“需要”解时,后面接-ing分词或不定式的被动式。如:
The room wants cleaning/to be cleaned. 这个房间需要打扫。
These little children require looking after carefully/to be looked after carefully.
这些小孩需要细心地照料。
⑤动词like, hate, prefer等后面,如表示一般性动作,多用-ing分词;如指特定的具体的某次动作,多用不定式。如:
I like swimming, but I don’t like to swim with you. 我喜欢游泳,但我不喜欢和你一起游泳。
I prefer walking to school every day. 我情愿每天步行去学校。
I prefer to stay at home today. 今天我情愿呆在家里。

We began to do that job last year. 我们去年开始做那工作的。
They started talking about the film at once. 他们立刻开始谈论那部电影。
注:下面几种情况多用不定式作宾语:
a. 当start, begin本身用于进行时态时。
When the teacher came into the room, he was starting to write to his parents.
老师走进教室的时候,他正开始写信给他的父母亲。
b. 当start, begin后接表示心理活动的动词时。
Hearing the news, he started to think of a good way to solve the problem.
一听到消息,他就开始考虑一个好办法来解决这个问题。
c. 当句子的主语是无生命的东西时。
We were about to leave when it began to rain. 我们正准备离开,天开始下雨了。
4. -ing分词作表语的两种不同含义:
①-ing分词作表语可以表示主语的内容是什么。如:
Their job is building houses. 他们的工作是盖房子。
The real question is getting to know the needs of the people. 真正的问题是了解人民的需要。
②-ing分词作表语还可以表示主语所具有的特征。如:
This story is very interesting. 这故事很有趣。
The problem is quite puzzling. 这个问题很令人困惑。
①–ing分词作定语可用来说明被修饰的名词的用途和性能。如:
reading material 阅读材料 walking stick 手杖 fishing pole 鱼杆
flying suit 飞行服 writing table 写字台 listening practice 听力训练
②-ing分词作定语还可以表示所修饰的人或物的动作或状态,在意思上接近一个定语从句,可以表示正在进行的动作,也可表示经常性动作或当时的状态。如:
developing countries = countries that are developing 发展中国家
a growing city = a city that is growing 发展着的城市
an ordinary-looking house = a house that looks ordinary 看起来很普通的房子
a touching story = a story that is touching 一个动人的故事
working people= people who are working 劳动人民
6. 不定式和-ing分词作宾语补语的区别:
在see, hear, feel, watch, notice等感官动词后,既可用-ing分词构成复合宾语,也可用不定式构成复合宾语,两者之间有一定的区别。用-ing分词时,表示动作正在进行;用不定式时,表示动作发生了,即动作的全过程结束了。如:
Do you hear someone knocking at the door? (Someone is knocking at the door.) 有人在敲门你听见了吗?
Do you hear someone knock at the door? (Someone knocked at the door just now.) 你听见有

㈥ 高中英语语法句型(全一点哦)
非谓语动词
在句子中充当除谓语以外的句子成分的动词形式叫做非谓语动词。非谓语动词分为三种形式:不定式,动名词,和分词(分词包括现在分词和过去分词)。
1)不定式
时态\语态 主动 被动
一般式 to do to be done
完成式 to have done to have been done
2)动名词
时态\语态 主动 被动
一般式 doing being done

3)分词
时态\语态 主动 被动
一般式 doing being done
完成式 having done having been done
否定形式: not +不定式, not + 动名词, not + 现在分词
倒装句之全部倒装
全部倒装是只将句子中的谓语动词全部置于主语之前。此结构通常只用与一般现在时和 一般过去时。常见的结构有:
1) here, there, now, then, thus等副词置于句首, 谓语动词常用be, come, go, lie, run。
There goes the bell.
Then came the chairman.
Here is your letter.
2) 表示运动方向的副词或地点状语置于句首,谓语表示运动的动词。
Out rushed a missile from under the bomber.
Ahead sat an old woman.
注意:上述全部倒装的句型结构的主语必须是名词,如果主语是人称代词则不能完全倒装。
Here he comes. Away they went.
倒装句之部分倒装
部分倒装是指将谓语的一部分如助动词或情态倒装至主语之前。如果句中的谓语没有助动词或情态动词,则需添加助动词do, does或did,并将其置于主语之前。
1) 句首为否定或半否定的词语,如no, not, never, seldom, little, hardly, at no time, in no way, not until… 等。
Never have I seen such a performance.
Nowhere will you find the answer to this question.
Not until the child fell asleep did the mother leave the room.
当Not until引出主从复合句,主句倒装,从句不倒装。
注意: 如否定词不在句首不倒装。
I have never seen such a performance.
The mother didn't leave the room until the child fell asleep.
典型例题
1) Why can't I smoke here?
At no time___ in the meeting-room
A. is smoking permitted B. smoking is permitted
C. smoking is it permitted D. does smoking permit
答案A. 这是一个倒装问题。当否定词语置于句首以表示强调时,其句中的主谓须用倒装结构。 这些否定词包括no, little, hardly, seldom, never, not only, not until等。本题的正常语序是 Smoking is permitted in the meeting-room at no time.
2) Not until the early years of the 19th century ___ what heat is.
A. man did know B. man know C. didn't man know D. did man know
答案D. 看到Not until…的句型,我们知道为一倒装句,答案在C,D 中选一个。
改写为正常语序为,Man did not know what heat is until the early years of the 19th. 现在将not提前,后面就不能再用否定了,否则意思就变了。
以否定词开头作部分倒装
如 Not only…but also, Hardly/Scarcely…when, No sooner… than
Not only did he refuse the gift, he also severely criticized the sender.
Hardly had she gone out when a student came to visit her.
No sooner had she gone out than a student came to visit her.
典型例题
No sooner___ than it began to rain heavily.
A. the game began B. has the game begun
C. did the game begin D. had the game begun
答案D. 以具有否定意义的副词放在句首时,一般采用倒装句(谓语前置)。这类表示否定意义的词有never, seldom, scarcely, little, few, not, hardly, 以及not only…but (also), no sooner…than, hardly… when scarcely… when 等等。
注意:只有当Not only… but also连接两个分句时,才在第一个分句用倒装结构。如果置于句首的Not only… but also仅连接两个并列词语,不可用倒装结构。
Not only you but also I am fond of music.
so, neither, nor作部分倒装
表示"也"、"也不" 的句子要部分倒装。
Tom can speak French. So can Jack.
If you won't go, neither will I.
典型例题
---Do you know Jim quarrelled with his brother?
---I don't know, _____.
A. nor don't I care B. nor do I care C. I don't care neither D. I don't care also
答案:B. nor为增补意思"也不关心",因此句子应倒装。A错在用 don't 再次否定, C neither 用法不对且缺乏连词。 D缺乏连词。
注意: 当so引出的句子用以对上文内容加以证实或肯定时,不可用倒装结构。意为"的确如此"。
Tom asked me to go to play football and so I did.
---It's raining hard. ---So it is.
only在句首要倒装的情况
Only in this way, can you learn English well.
Only after being asked three times did he come to the meeting.
如果句子为主从复合句,则主句倒装,从句不倒装
Only when he is seriously ill, does he ever stay in bed.
as, though 引导的倒装句
as / though引导的让步从句必须将表语或状语提前 (形容词, 副词, 分词, 实义动词提前)。
注意:
1) 句首名词不能带任何冠词。
2) 句首是实义动词, 其他助动词放在主语后。如果实义动词有宾语和状语, 随实义动词一起放在主语之前。
Try hard as he will, he never seems able to do the work satisfactorily.
注意:
让步状语从句中,有though,although时,后面的主句不能有but,但是 though 和yet可连用。
其他部分倒装
1) so… that 句型中的so 位于句首时,需倒装。
So frightened was he that he did not dare to move an inch.
2) 在某些表示祝愿的句型中:
May you all be happy.
3) 在虚拟语气条件句中从句谓语动词有were, had, should等词,可将if 省略,把 were, had, should 移到主语之前,采取部分倒装。
Were I you, I would try it again.
典型例题:
1) Not until the early years of the 19th century___ what heat is
A. man did know B. man knew C. didn't man know D. did man know
答案为D. 否定词Not在句首,要求用部分倒装的句子结构。
2) Not until I began to work ___ how much time I had wasted.
A. didn't I realize B. did I realize C. I didn't realize D. I realize
答案为B。
3) Do you know Tom bought a new car?
I don't know, ___.
A. nor don't I care B. nor do I care
C. I don't care neither D. I don't care also
解析:答案为B. 句中的nor引出部分倒装结构,表示"也不"。由 so, neither, nor引导的倒装句,表示前一情况的重复出现。其中, so用于肯定句, 而 neither, nor 用在否定句中。
名词性从句
在句子中起名词作用的句子叫名词从句 (Noun Clauses)。 名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等,因此根据它在句中不同的语法功能,名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
引导名词性从句的连接词
引导名词性从句的连接词可分为三类:
连接词:that,whether,if 不充当从句的任何成分)
连接代词:what, whatever, who, whoever, whom,
whose, which.
连接副词:when, where, how, why
不可省略的连词:
1. 介词后的连词
2. 引导主语从句和同位语从句的连词不可省略。
That she was chosen made us very happy.
We heard the news that our team had won.
比较:whether与if 均为"是否"的意思。 但在下列情况下,whether 不能被if 取代:
1. whether引导主语从句并在句首
2. 引导表语从句
3. whether从句作介词宾语
4. 从句后有"or not"
Whether he will come is not clear.
大部分连接词引导的主语从句都可以置于句末,用 it充当形式主语。
It is not important who will go.
It is still unknown which team will win the match.
名词性that-从句
1)由从属连词that引导的从句叫做名词性that-从句。 That只起连接主句和从句的作用,在从句中不担任任何成分,本身也没有词义。名词性that-从句在句中能充当主 语、宾语、表语、同位语和形容词宾语,例如:
主语:That he is still alive is sheer luck. 他还活着全靠运气。
宾语:John said that he was leaving for London on Wednesday. 约翰说他星期三要到伦敦去。
表语:The fact is that he has not been seen recently. 事实是近来谁也没有见过他。
同位语:The fact that he has not been seen recently disturbs everyone in his office.
近来谁也没有见过他,这一事实令办公室所有的人不安。
形容词宾语:I am glad that you are satisfied with your job.
你对工作满意我感到很高兴。
2)That-从句作主语通常用it作先行词,而将that-从句置于句末,例如:
It is quite clear that the whole project is doomed to failure. 很清楚,整个计划注定要失败。
It's a pity that you should have to leave. 你非走不可真是件憾事。
用it作形式主语的that-从句有以下四种不同的搭配关系:
a. It + be +形容词+ that-从句
It is necessary that… 有必要……

名词性wh-从句
1)由wh-词引导的名词从句叫做名词性wh-从句。Wh-词包括who, whom,. whose, whoever, what, whatever, which, whichever等连接代词和where, when, how, why等连接副词。Wh-从句的语法功能除了和that-从句一样外,还可充当介词宾语、宾语补语和间接宾语等,例如:
主语: How the book will sell depends on its author. 书销售如何取决于作者本人。
直接宾语:In one's own home one can do what one likes. 在自己家里可以随心所欲。
间接宾语:The club will give whoever wins a prize.
俱乐部将给得胜者设奖。
表语: My question is who will take over president of the Foundation. 我的问题是谁将接任该基金会主席职位。
宾语补足语:She will name him whatever she wants to. 她高兴给他起什么名字就取什么名字。
同位语: I have no idea when he will return.
我不知道他什么时候回来。
形容词宾语:I'm not sure why she refused their invitation. 我尚不能肯定她为什么拒绝他们的邀请。
介词宾语: That depends on where we shall go.
那取决于我们去哪儿。
2)Wh-从句作主语也常用先行词it做形式主语,而将wh-从句置于句末,例如:
It is not yet decided who will do that job.
还没决定谁做这项工作。
It remains unknown when they are going to get married. 他们何时结婚依然不明。
if, whether引导的名词从句
1)yes-no型疑问从句
从属连词if, whether引导的名词从句是由一般疑问句或选择疑问转化而来的,因此也分别被称为yes-no型疑问句从句和选择型疑问从句,其功能和wh-从句的功能相同, 例如:
主语:Whether the plan is feasible remains to be proved. 这一计划是否可行还有等证实。
宾语:Let us know whether / if you can finish the article before Friday. 请让我们知道你是否能在星期五以前把文章写完。
表语:The point is whether we should lend him the money. 问题在于我们是否应该借钱给他。
同位语:They are investigating the question whether the man is trustworthy. 他们调查他是否值得信赖。
形容词宾语: She's doubtful whether we shall be able to come. 她怀疑我们是否能够前来。
介词宾语: I worry about whether he can pass through the crisis of his illness. 我担心他是否能度过疾病的危险期。
2)选择性疑问从句
选择性疑问从句由关联词if/whether…or或whethe…or not构成,例如:
Please tell me whether / if they are Swedish or Danish. 请告诉我他们是瑞典人还是丹麦人。
I don't care whether you like the plan or not.我不在乎你是否喜欢该计划。
㈦ 英语语法及例句
语言要遵循一定的规则,这种规则即被我们称之为“语法”。许多学生在英语学习中一听“语法”头就大,产生恐惧、厌学的心理。教师要遵循“精讲多练,讲练结合,以练为主”的教学方法,同时还要注意提高学习效率,减轻学生的作业负担,实现语言为交流工具的目的。笔者在多年的教学实践中总结:语法教学要重视例句的选择。
一、代表性
例句的选择在结构上要有代表性,起到掌握这个句型就能够举一反三的作用。历年的高考试题、学生比较熟悉的经典习题等,我们不妨拿来一试。
如,讲动词不定式的主动式和被动式:
She went to the ball not only to see,but also to be seen.(她去参加舞会不仅为了见见世面。也为了出出风头。)
如with复合结构,即with+宾语+宾语补足语:
With two exams to worry about,I have to work really hard this weekend.(2004,北京)
关于情态动词must have done 表对过去情况肯定的猜测:
I have lost one of my gloves. I must have dropped it somewhere. (2005,北京)
二、简洁性
有些教师认为,例句越难越好,难的会了容易的就更会了;还有教师因为学生上课不好好听课,主张选难懂的句子来镇镇他们。其实不然。正如人的认知规律“由易到难”,对于语法学习有困难的学生而言,复杂的例句只会让他们更头痛,对语法更畏惧,对英语学习更没兴趣。选择结构简洁的例句,语言上通俗易懂,读来朗朗上口,学生容易记,也记得牢。
如讲动词不定式的语法功能时:
1.
He is always the first to come and the last to leave.(to do 不定式作定语,修饰序数词)
2.
To see is to believe.(to do 不定式坐主语和表语)
对比学习Seeing is believing.(动名词作主语和表语)
3.
It is easier to say something than to do something. (to do 不定式作句子的真正主语,It为形式主语)
对比学习It is easier said than done.
三、趣味性
兴趣是产生学习激情的巨大动力。选择内容生动有趣的例句,如谚语、成语、俚语等,这样学生有了兴趣,就愿意多念,念熟了就能由次及彼。
如: 倒装结构“so+助动词+主语+谓语+------”:
As a man lives,so shall he dies.(有生就有死)
As a man sows, so shall he reap.(种瓜得瓜。种豆得豆)
下边还有一个比较级的句子:
The old man was not any more fond of being read to than the old woman.
此句的翻译为“那个老头和老太太一样,都喜欢别人读书给他们听”。有学生将它译为“那个老头不喜欢别人给他念书,就喜欢哪个老太太”,这就要闹笑话了。
四、积极性
选择一些内容积极向上的语法例句,如名言警句等。这不仅能让学生掌握相应的语法知识,同时也起到教育的情感目的,起到教育人的作用。
One half of knowing what you want is knowing what you must give up before you get it.
知道想要什么,一半在于知道得到它之前必须放弃什么。 (表语从句)
Victory will not come to me unless I go to it. 胜利是不会向我走来的,我必须自己走向胜利。 (条件状语从句)
All that litters is not gold. 闪光的并非都是金子。 (定语从句)
五、综合性
在实际的语法教学中,很少有独立的语法项目,很多时候许多的语法知识汇集在一个句中。选择综合性较强的例句来讲解,让学生背诵,能起到事半功倍的效果。如:
It was playing computer games that cost the boy much time he ought to have spent in doing his lessons.
这个例句综合了:
强调句型:It was---that---
定语从句:---time (that) he ought to have---lessons
情态动词:ought to have spent---
动名词作主语:---playing computer games cost the boy much more time---
总之,适当的例句选择不仅能够让学生理解语法,掌握重点,还能在茫茫题海中减轻学生大量背诵和大量习题的课业负担,有效提高教学质量。教师要注意多研究,多积累,找出更多的语法教学方法。

9、被修饰成分为表语,或者关系代词本身是定语从句的表语时,该关系代词宜用that。
10、先行词为what,关系代词用that。
11、有时为了避免重复而使用that引导定语从句。

(2)含有介词的短语动词一般不拆开,介词仍放在动词的后面。
(3)关系代词that在从句中作介词宾语时,介词不能放在它的前面,只能放在从句中有关动词的后面。
(4)关系代词whose也可以在从句中与它所修饰的名词一起作介词宾语。

注意:关系词在从句中必须作状语。如果关系词在从句中作主语或宾语,按正常的定语从句分析。
2、当先行词是time时,若time作“次数”讲,应用that引导定语从句,that可省略;若time作“一段时间”讲,应用关系副词when或介词at/ring+which引导定语从句。
㈨ 高中英语语法
你提了一个很抄好的问题袭。图片例句里,have failed是完成时,表示已经完成的动作。这个例句没有上下文,我个人认为不加have也是可以的,例如:She was ashamed of failing the examination.
