简单句、并列句、复合句

1、简单句、并列句、复合句根据语法形式，即句子的结构，英语的句子可分为简单句、并列句和复合句。1 简单句句型 : 主语+谓语只包含一个主谓结构，而句子的各个结构都只由单词或短语表示They are playing baseball in the garden.他们正在公园里打棒球。Her brother and sister both are teachers.她的哥哥和姐姐都是老师。2 并列句句型 : 简单句 +并列连词+简单句(常见的并列连词有and， but， or)并列句是由两个或两个以上的简单句连接而成。并列句中的各简单句意义同等重要，相互之间没有从属关系，是平行并列的关系。它们之间用连

2、词连结。Her father is a doctor and her mother is a teacher.Iliked the story very much but Li Ming wasn''t interested in it.Hurry up ， or you''ll be late.3 复合句句型 :主句+连词+从句;或连词+从句+主句(包含一个主句、一个或一个以上的从句，或只包含一个从句，但有两个或两个以上的主句的句子叫复合句。)复合句 (The Complex Sentence): 句子中有一个或一个以上的从句，叫做复合句。复合句可分为:1)

3、.定语从句(The Attributive Clause);2) .状语从句(The Adverbial Clause);3) .名词性从句(The Noun Clause):一、 定语从句定语从句的定义定语从句在句子中作定语，用来修饰一个名词、名词词组或者代词。先行词和引导词被修饰的名词、名词词组或代词叫做先行词;在先行词和定语从句之间起连接作用的词叫做引导词。引导词分为“关系代词”和“关系副词”。关系代词和关系副词关系代词有:who, whom, whose, that, which, as 。关系副词有:when, where, why 。 注意 :关系副词里面没有how。如果要修饰方式

4、，用that 或 in which 引导，或者不用引导词。I don t like the way (that, in which) he eyed me.我不喜欢他看我的那个样子。关系代词:who关系动词who 在从句中主要作主语，在非正式语体里who 还可以作从句中的宾语。He is the man who wants to see you.He is the man who I saw in the park yesterday.关系代词:whomHe is the man (whom) I saw in the park yesterday.(whom 在从句中作宾语)关系代词:who

5、sewhose 用来指人或物，(只能用作定语, 若指物，它还可以同of which 互换 )。They rushed over to help the man whose car had broken down.Please pass me the book whose cover is green. (of which the cover/the cover of which)关系代词:which(1)which 指物，在从句中作主语或宾语，作宾语时在非正式语体中可以省略。They needed a plant which didn't need as much water as r

6、ice.The farm (which) we visited yesterday is located in the suburb of Beijing.关系代词:which(2)当在 which 和 that 面前进行选择的情况下，一下情况要选which:1. 在非限制性定语从句中通常用which 作引导词，而不能用that 做非限制性定语从句的引导词。2. 修饰整个主句。Inever met Julia again after that, which was a pity.3. 修饰谓语部分。He can swim in the river, which I cannot.4. 介词 +

7、 whichThey are all questions to which there are no answers.关系代词:that(1)that多用来指物，有时也可以用来指人；在从句中作主语或宾语。指物的时候多用 that,也可用which 。Its a question that (which) needs careful consideration.( 指物，作主语。)Who is the man that is reading a magazine under the tree?( 指人，作主语。)The girl (that) we saw yesterday is Tom s

8、sister.( 指人，作宾语，可省略。)关系代词:that(2)在以下的情况中，只能用that 作引导词，而不能用which 作引导词。1. 先行词为all , everything, anything, nothing, little 等不定代词时。All (that) she lacked was training.2. 先行词被形容词最高级修饰时This is the best film that I have ever seen.3. 先行词被序数词和the last 修饰时4. 先行词中既有人又有物时They talked about the teachers and the sc

9、hools that they had visited.5. 主句是含有who 或 which 的特殊疑问句，为了避免重复时二、 状语从句1 地点状语从句地点状语从句通常由where, wherever 引导。Where I live there are plenty of trees.Wherever I am I will be thinking of you.2 方式状语从句方式状语从句通常由as, (just) as - so- -, as if, as though引导。1) as, (just) asso引导的方式状语从句通常位于主句后，但在 (just) asso结构中位于句首，

10、 这时as从句带有比喻的含义，意思是"正如"，"就像"，多用于正式文体，例如 ：Always do to the others as you would be done by.你希望人家怎样待你，你就要怎样待人。As water is to fish, so air is to man.我们离不开空气，犹如鱼儿离不开水。Just as we sweep our rooms, so we should sweep backward ideas from our minds.正如打扫房屋一样，我们也要扫除我们头脑中落后的东西。2) as if, as tho

11、ugh两者的意义和用法相同，引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，表示所说情况是事实或实现的可能性较大。汉译常作"仿佛似的"，"好像似的"，例如:They completely ignore these facts as if (as though) they never existed.他们完全忽略了这些事实，就仿佛它不存在似的。(与事实相反，谓语用虚拟语气。)He looks as if (as though) he had been hit by lighting.他那样子就像被雷击了似的。(与事实相反，谓语用虚拟语气。

12、)It looks as if the weather may pick up very soon.看来天气很快就会好起来。(实现的可能性较大，谓语用陈述语气。)说明 :as if / as though 也可以引导一个分词短语、不定式短语或无动词短语，例如:He stared at me as if seeing me for first time.他目不转睛地看着我，就像第一次看见我似的。He cleared his throat as if to say something.他清了清嗓子，像要说什么似的。3) 原因状语从句比较 :because, since, as 和 for1) be

13、cause语势最强，用来说明人所不知的原因，回答 why提出的问题。当原因是显而易见的或已为人们所知，就用as 或since。Ididn't go, because I was afraid.Since /As the weather is so bad, we have to delay our journey.2) 由 because 引导的从句如果放在句末，且前面有逗号，则可以用for 来代替。但如果不是说明直接原因，而是多种情况加以推断，就只能用for 。He is absent today, because / for he is ill.He must be ill, fo

14、r he is absent today.4 目的状语从句表示目的状语的从句可以由that, so that, in order that, in case 等词引导，例如:You must speak louder so that /in order that you can be heard by all.Better take more clothes in case the weather is cold.5 结果状语从句结果状语从句常由sothat或suchthat引导，掌握这两个句型，首先要了解so和such与其后的词的搭配规律。比较 :so 和 such其规律由so 与 such

15、 的不同词性决定。such 是形容词，修饰名词或名词词组，so 是副词，只能修饰形容词或副词。so 还可与表示数量的形容词many, few, much, little 连用，形成固定搭配。so foolish such a foolso nice a flower such a nice flowerso many / few flowers such nice flowersso much / little money. such rapid progressso many people such a lot of people（so many已成固定搭配，a lot of虽相当于 man

16、y,但a lot of为名词性的，只能用 such搭配。） sothat与suchthat之间的转换既为so与such之间的转换。The boy is so young that he can't go to school.He is such a young boy that he can't go to school6 条件状语从句连接词主要有if, unless, as/so long as, on condition that 等。 .if 引导的条件句有真实条件句和非真实条件句两种。非真实条件句已在虚拟语气中阐述。unless = if not.Let's g

17、o out for a walk unless you are too tired.If you are not too tied, let's go out for a walk.7 让步状语从句though, although注意：当有though, although时，后面的从句不能有but,但是though和yet可连用Although it's raining, they are still working in the field.3） ever if, even though. 即使We'll make a trip even though the wea

18、ther is bad.4） whether or-不管都Whether you believe it or not, it is true.5） "no matter + 疑问词 " 或 "疑问词+后缀ever"No matter what happened, he would not mind.Whatever happened, he would not mind.替换 :no matter what = whateverno matter who = whoeverno matter when = wheneverno matter where

19、= whereverno matter which = whicheverno matter how = however注意 :no matter 不能引导主语从句和宾语从句。（错 ）No matter what you say is of no use now.（对 ）Whatever you say is of no use now.你现在说什么也没用了。（Whatever you say 是主语从句）（ 错 ）Prisoners have to eat no matter what they're given,（ 对 ）Prisoners have to eat whatever

20、 they're given. 囚犯们只能给什么吃什么。8 比较 while, when, as1）as, when 引导短暂性动作的动词。Just as / Just when / When I stopped my car, a man came up to me.2）当从句的动作发生于主句动作之前，只能用when 引导这个从句，不可用as 或 while 。When you have finished your work, you may have a rest.3）从句表示"随时间推移"连词能用as,不用when或while。As the day went

21、on, the weather got worse.日子一天天过去，天气越变越坏。9 比较 until 和 till此两个连词意义相同。肯定形式表示的意思是"做某事直至某时"，动词必须是延续性的。否定形式表达的意思是"直至某时才做某事"。 动词为延续性或非延续性都可以。 正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。肯定句 :Islept until midnight. 我一直睡到半夜时醒了。Wait till I call you. 等着我叫你。(在肯定句中可用before 代替 Let's get in the whe

22、at before the sun sets.)否定句 :She didn't arrive until 6 o'clock.Don't get off the bus until it has stopped.1)Until 可用于句首，而till 通常不用于句首。Until you told me, I had heard nothing of what happened.直到你告诉我以前，出了什么事我一点也不知道。2)Until when 疑问句中，until 要放在句首。注意 : 否定句可用另外两种句式表示。(1)Not until在句首，主句用倒装。Not u

23、ntil the early years of the 19th century did man know what heat is.直到 19 世纪初，人类才知道热能是什么。Not until I began to work did I realize how much time I had wasted.直到我开始工作，我才认识到了我已蹉跎了几多岁月。(2) It is not until that 10表示"一就"的结构hardly/scarcely when/before, no sooner than 和 as soon as者B可以表示 "就"

24、;的意思，例 : Ihad hardly / scarcely got home when it began to rain.Ihad no sooner got home than it began to rain.As soon as I got home, it began to rain.注意 :如果 hardly, scarcely 或 no sooner 置于句首，句子必须用倒装结构:Hardly / Scarcely had I got home when it began to rain.No sooner had I got home than it began to rai

25、n.三、 名词性从句1） .宾语从句(The Object Clause);宾语从句在句子中起宾语作用的从句叫做宾语从句。宾语从句的引导词和主语从句的引导词相同。宾语从句可以作及物动词的宾语，作短语动词的宾语，介词的宾语。宾语从句:及物动词Everybody knows that money doesn't grow on trees.宾语从句:短语动词Please go and find out when the train will arrive.宾语从句:介词的宾语Iam interested in what she is doing.宾语从句:否定的转移Idon't s

26、uppose you're used to this diet.我想你不习惯这种饮食。Idon't believe she'll arrive before 8.我相信她8 点之前不会到。2） .表语从句（The Predicative Clause）;表语从句在句子中起表语作用的从句叫做宾语从句。表语从句的引导词和主语从句的引导词相同。What the police want to know is when you entered the room.This is what we should do.That's why I want you to work there.as if, as though, because 也可用来引导表语从句。She seems as if she had done a great thing.It is because you eat too much.虚拟语气:表语从句主语是 idea, notion, proposal, suggestion, request 等名词时, 作表语从句的动词为原形动词或should+原形动词。My suggestion is that we （should） go and help him.Our o
