1、句型结构按照句子结构可以分为:简单句、并列句和复合句。一、简单句:基本句型结构:主系表结构:本结构是由主语+系动词+表语组成,主要用以说明主语的特征,类属,状态,身份等。系动词有:1.表示特征和存在状态的 be, seem, feel, appear, look, smell, taste, sound;2.表示状态延续的 remain, stay, keep, continue, stand;3.表示状态变化的become, get, turn, go, run, fall, come, grow;例如:Our English teacher is thirty years old. The
2、 cake tastes delicious. The potatoes went bad in the fields. Deep water stays still.He was at work. She is in good health.It is beyond my ability. I was at a loss. You are under arrest。主谓结构:本结构是由主语加不及物的谓语动词构成, 常用来表示主语的动作。如:The sun rises. Tom has already left. 主语可有修饰语-定语,谓语可有修饰语-状语。如: 1. The red sun
3、rises in the east.2. They had to travel by air or boat.3. She sat there alone.4. He came back when we were eating.5. Weak buildings will fall down in an earthquake。主谓宾结构:本结构是由主语+及物的谓语动词+宾语构成。1. Tom made a hole in the wall. 2. I dont know if he can come tomorrow. 3. They havent decided where to go ne
4、xt. 4. She stopped teaching English two years ago 双宾语结构 主语+及物谓语动词+间接宾语(人)+直接宾语(事物)”组成He brings me cookies every day.但若要先说出直接宾语(事物),后说间接宾语(人),则要借助于介词to或for。如: He brings cookies to me every day.She made a beautiful dress for me.用to侧重指动作的方向,表示朝着,向着,对着某人。用for 侧重指动作的受益者,表示为了某人,替某人。常跟双宾语的动词有:(需借助to的)bring
5、, give, lend, hand, offer, pass, pay, promise, return, send, show, teach, tell, write, ask等;(需借助for 的) buy, call, cook, choose, draw, find, get, make, order, sing, save, spare等。复合宾语结构: 此结构由“主语+及物的谓语动词+宾语+宾语补足语”构成。宾语补足语用来补充和说明宾语的性质和特点,若无宾语补足语,则句意不够完整。可以用做宾补的有:名词,形容词,副词,介词短语,动词不定式,分词等。如: The sun keeps
6、 us warm. I heard him singing.They made Tom monitor.He used to do his homework with his radio on.My mother asked me to clean my room.The teacher made all students finish their homework on time.用 it 做形式宾语,而将真正的宾语放到宾语补足语的后面,以使句子结构平衡,是英语常用的句型结构方式。即:主语+谓语+it+宾补+真正宾语。如:I found it very pleasant to be with
7、 your family.I found it was pleasant to be with your family. 它们的区别在于第一个是简单句第二个是复合句,意思都是一样的。There be 句型:此句型是由“there+be+主语+状语”构成,用以表达存在关系可以称“有存在着”。它其实是全倒装的一种情况,主语位于谓语动词 be 之后,there 仅为引导词,并无实际语意。此句型有时不用be动词,而用 live, stand, come, go, lie, remain, exist, arrive等,但一般不用have。如:There stands a hill in the mid
8、dle of the park. Once upon a time there lived an old king in the town. Be 与其后的主语在人称和数量上一致,有时态和情态变化。如: 现在有 there is/are 过去有 there was/were 将来有 there will be;there is /are going to be. 现在已经有 there has/have been 可能有 there might be. 肯定有 there must be /there must have been. 过去曾经有 there used to be 似乎有 the
9、re seems/seem/seemed to be 碰巧有 there happen/happens/happened to be Once, there lived an old fisherman in a village by the sea. The weatherman says therell be a strong wind in the afternoon. There used to be a cinema here before the war. 二、并列句结构:1.由分号连接。eg. Some people cry; others laugh.Lets start ea
10、rly; we have a long way to go.2.由并列连词及词组连接-and/ but /or/ so / however / still/ therefore /yet /while /otherwise /for /bothand/not onlybut also/as well as/or else/ eitheror/neithernor/notbut等。eg: Id like to, but I have lots of homework to do.Ive got a cold, so Im going to bed.Both my father and mothe
11、r are teachers.Its very good, yet I dont like it.三、复合句构成:由一个主句和一个或一个以上的从句构成。主句和从句都有完整的主谓结构,但主句是全局的主体,从句只是全句中的一个成分,不能独立存在。从句通常是用引导词来引导的,引导词起连接主句和从句的作用。分类:名词性从句(主语从句、表语从句、宾语从句和同位语从句),形容词性从句(定语从句),副词性从句(状语从句)。名词性从句:性质相当于名词的从句.注意:1.名词性从句的一般引导词1. 连接词 that 引导名词性从句时,只起连接作用,没有任何意思,也不充当句子成分,在宾语从句中可省略,但引导其他名词
12、性从句时通常不省略。如:I hope (that) you enjoy your holiday. 希望你假期过得好。he likes you is very obvious. 很显然他喜欢你。2. 连接词 whether 引导名词性从句也不充当句子成分,但有自己的意思,表示“是否”;引导宾语从句时,可换成 if,但引导其他名词性从句时不能换成 if。如(from ):He asked whether if I would show him the way. 他问我是否可以给他带路。Whether it will do us harm remains to be seen. 是否对我们有害还要
13、看一看。(引导主语从句,不能用 if 代替 whether)3. 连接代词 who(m), whose, which, what 等引导名词性从句时,均有各自的意义,在从句中作主语、宾语、定语等。如:Thats why she wanted to leave. 这就是她想离开的原因。When we arrive doesnt matter. 什么时候到没有关系。Tell me which one you like best. 告诉我你最喜欢哪一个。4. 连接副词 when, where, why, how 等引导名词性从句,也各自有自己的意义,在从句中作状语。如:The question is
14、 how we should carry out the plan. 问题是怎样执行这个计划。When shell be back depends much on the weather. 她什么时候回来在很大程度上要看天气。Why he did it will remain a puzzle forever. 他为什么这样做将永远是一个谜。2.名词性从句的重要引导词1. what 用于引导名词性从句是一个十分重要的引导词,它可引导主语从句、宾语从句和表语从句,但不用于引导同位语从句。它引导的名词性从句有两个意思是:一是表示“什么”,带有疑问意味;二是表示“所的”,相当于一个先行词后接一个关系
15、代词。如:I dont know what you want. 我不知道你想要什么。I dont know what you want is this. 我不知道你所想要的是这个。2. what 引导名词性从句时可用作限定词,其后修饰名词。如:I gave him what books I had. 我把我所有的书都给他了。He gave me what money he had about him. 他把身边带有的钱全给了我。注:what 后的名词可以是复数名词或不可数名词,但通常不能是单数可数名词,并且后接不可数名词时,有时可有little修饰,两者的区别是:what+不可数名词=所有的都
16、,what little+不可数名词=虽少但全部。如:What friends she has are out of the country. 她有的那些朋友全在国外。We gave him what (little) help we could. 我们给了他我们力所能及的帮助。3. whoever, whatever, whichever 等也可引导名词性从句,其意分别为“所的一切事或东西”、“任何的人”、“的任可人或物”等。如:Whoever wants the book may have it. 任何人要这书都可拿去。Ill do whatever I can to help him.
17、我们将尽我们所能来挽救他。Buy whichever is cheapest. 买最便宜的。注意以下受汉语意思影响而弄错的句子:任何人来都欢迎(from )。误:Who comes will be welcome. / Anyone comes will be welcome.正:Whoever comes will be welcome. / Anyone who comes will be welcome.另外,它们也可引导让步状语从句,其意为“无论”、“不管”,其意相当于 no matter who what, which。如:Whatever happens, you must be
18、calm. 不管发生什么情况,你都必须镇静。(whatever = no matter what)He wont eat you, whoever he is. 不管他是谁,他也不能把你吃掉。(whoever = no matter who)注:whoever 引导名词性从句时既用作主格也用作宾语;作宾语时不宜用 whomever,因为在现代英语中 whomever 这个已几乎废弃不用。4. why与because 的用法区别。两者均可引导表语从句,但前者强调结果,后者强调的原因。如:I had a cold. Thats why I didnt come. 我感冒了,因此我没来。I didn
19、t come. Thats because I had a cold. 我没有来,那是因为我感冒了3名词性从句的语序名词性从句的词序与陈述句语序相同,尤其注意那些由连接代词who(m), whose, which, what 和连接副词 when, where, why 等引导的名词性从句,不要受它们在特殊疑问句中用法的影响而误用疑问句词序。如:Why was she crying? 她为什么在哭?I dont know why he was crying. 我不知道她为什么哭。4名词性从句的时态问题1. 当主句的谓语动词是过去式时,宾语从句若不是一个客观事实或真理,其谓语动词也必须用某种过去
20、时态。如:She said that she didnt want to know. 她说她不想知道。I asked her whether she would agree. 我问她是否会同意(from )。2. when, if 这两个词既可引导名词性从句,也可引导状语从句。当它们引导名词性从句且表示将来意义时,要直接使用将来时态;但当它们引导状语从句且表示将来意义时,则必须用一般现在时表示将来意义。如:I dont know when he will come, but when he comes, Ill call you. 我不知道他什么时候,但当他来的时候,我会打电话给你。句中第一个
21、when 引导的是宾语从句,故用将来时态表示将来意义;第二个when 引导的是时间状语从句,故用一般现在时表示将来意义。主语从句(Subject Clause):一个句子在复合句中充当一个主语,那么这个句子就是主语从句。句子在复合句中充当主语That he finished writing the composition in such a short time surprised us all. Whether we will go for an outing tomorrow remains unknown. Who will be our monitor hasnt been decid
22、ed yet. Whom we must study for is a question of great importanceWhat caused the accident remains unknown. Whatever you did is right. Whose watch was lost is unknown. What we need is time.小结:(1)引导主语从句连词有that,whether,who,what,whatever等(2)连词位于句首不能省略(3)主语从句大多数情况下视为三人称单数。注意:为了防止句子头重脚轻,通常把形式主语it放在主语位置,真正主
23、语搁置于句末It is certain that he will win the match.It is true that he has made a very important discovery in chemistry.It is strange that he should do that.It is said that he has gone to shanghai.(=He is said to have gone to shanghai) It is known to all that the gun powder was first invented by the Chin
