1、首先还是讲一下句子结构吧,了解了这个对分析长难句很有帮助,以前高考前老师也是这么教我们的,还有熟悉了这个你写作文会比较好用从句,检查的时候也比较容易发现错误英语句子结构其实跟中文的有点像,主要有主语 谓语 宾语 定语 状语 补语 表语一个最简单的句子至少有主语 谓语这两部分 例如 I believe. (I 是主语 believe 是谓语)还有主系表（主语+系动词+ 表语，系动词是特殊的谓语啦，就是 be 的各种形态 am are is was were 那些再加上感官动词 smells looks sounds 这类的）例如 It sounds good.这类的 还有 It is nice.
2、 这里的 nice 跟 good 都是表语 表语都是跟在系动词后面的 不过我个人认为表语这个理解了就行 没有多大用处 纯粹是科普下百度了一下五个基本句型:.主语+动词(SV) Everybody laughed. 大家都笑了。 .主语+动词+补语 (SVC) His eyes are blue. 他的眼睛是蓝色的。 .主语+动词+宾语 (SVO) I love apples. 我喜欢苹果。 .主语+动词+宾语+宾语(SVOO) I gave him my address. 我告诉他我的地址。 .主语+动词+宾语+补语(SVOC) I found the box empty. 我发现盒子是空的。
3、然后句子复杂点的话 就多了定、状、补（不一定三个都有的，可以根据情况加一个两个或者三个都加）定语通常都是修饰名词的,所以主要是形容词,但也不一定,还可以是名词,代词,数词,动词不定式等例如: She is a student in No.7 Middle School. 黄底部分就是定语,修饰 student状语,顾名思义就是表示一个状态, 说明地点、时间、原因、目的、结果、条件、方向、程度、方式和伴随状况等,一般是由副词、介词短语、分词和分词短语、不定式或相当于副词的词或短语例如: She speaks English very well. very 是程度副词，用来修饰 well。very
4、 well 是修饰 speak的程度状语。She left ten minutes ago. Ten minutes ago 就是时间状语补语主要是宾语补足语 就是常说的宾补 这个全靠个人领会,我不会解释例如 She helps me to learn English.She made me angry.所谓的从句就是在这部分上用一个句子来表达的,我是这么理解的,对不对我就不知道了下面那些主要百度,部分手打补充1.主语从句 1）主语从句可直接位于主语的位置，如果从句较长，谓语又较短，可用 it 作形式主语，而将从句放在句末。常见的句型有： *It is a facta pitya questi
5、ongood news that. *It seemsappearshappenedhas turned out that. *It is clearimportantlikelypossible that. *It is saidreportedestimatedhas been proved that. It is said that comic books create a connection between people of the same generation. It seems that the performance is very useful. 2)what 引导的主语
6、从句表示“.的东西时” ，一般不用 it 作形式主语。 What we lack is experience. 3)what, who, when, why, whether 等词含有各自的疑问意义，但它们引导的主语从句，都用陈述语序。 How the plan is to be carried out should be discussed again. I did know why I felt like crying.(黄底那部分就是从句的部分,就是把主语那部分用一个句子表示)2.宾语从句 1）宾语从句可位于及物动词、介词和某些形容词后。连词 that 常可省略。介词后一般接疑问词引导的
7、宾语从句。in that(因为),except that(除了),but that(只是）已构成固定搭配，其他介词后一般不接 that 引导的宾语从句。 *I promised that I would change the situation. *All this is different from what American young people would say about friendship. *He is certain that watching so much television is not good for children. *This article is we
8、ll-written except that it is a bit too long. 2)宾语从句后如有宾补，要用形式宾语 it 来代替，而把宾语从句移至宾补之后。 He has made it clear that he would not change his mind. 3)在 think, believe, suppose, expect 等动词后的宾语从句中，如果谓语是否定的，一般将否定词移至主句谓语上，宾语从句则变成肯定形式。 He didnt think that the money was well spent.(其实我觉得这个原理跟主语从句差不多,就是一个是主语用句子来说
9、一个是宾语用句子来表达)3.表语从句 表语从句出现在结构为“主语+系动词+表语从句”的句子中。表语从句除可用 that, what, when, why, whether, how 等引导外，还可由 because, as if(though/although)等引导。that 常可省略。如主句主语为 reason,只能用 that 引导表语从句，不可用 because. Perhaps the most important thing to remember is that there is no one common type of life in America. The reason
10、why so many people died there is that there were not enough food supplies. It looks as if successful international cultural communication will make the world smaller.4.同位语从句 同位语从句用于对前面出现的名词作进一步说明，一般用连词 that 引导，由于先行名词的意义不同，也可用 whether, who, when, where, what, why, how 等引导。常见的先行名词有fact,idea,belief,new
11、s,hope,conclusion,evidence,suggestion,order,problem,report,decision.有时由于谓语较短，将同位语从句位于谓语之后。 She finally made the decision that she would join the fashion show. The fact that the earth is round is true. (that the earth is round 解释说明 the fact)5.定语从句 定语从句所修饰的先行词可以是名词或代词，也可以是一个句子。定语从句通常位于先行词之后，由关系代词或关系副词
12、引导。 *限制性定语从句 限制性定语从句修饰先行词，对先行词起修饰作用，紧接先行词之后，无逗号，若省去，原句意思不完整。引导定语从句的关系代词有 who, whom, whose, which, that 等。who, whom, whose 用于指人，whose 有时也可指物，相当于 of which；which 用于指物；that 既可指人也可指物，但只用于限制性定语从句中。关系代词除了引导定语从句，替代先行词外，还在从句中担任主语、宾语、定语等。 The computers and cables which make up the Internet are owned by people
13、 and organizations. Those who live alone or who are sick may have trouble in getting close to other people. (两个都是修饰 those)The girl whose parents died in an accident is living with her grandmother. 1)当先行词是 all ,anything ,everything, something, nothing 等不定代词或先行词前有 first ,last, any, few, much, some, no
14、, only 以及形容词最高级修饰时，只能用关系代词 that 引导从句。 That is all that Ive heard from him. Hes the first person that Im going to interview this afternoon. 2)关系代词的省略 在从句中作宾语的关系代词常可省略。关系代词紧跟介词，作介词宾语时不可用 that，只可用 which 或 whom 引导从句，并且不可省略，但当介词位于宾语从句句末时，作为介词宾语的关系代词仍可用 that，也可省略。 This is one of those things with which we
15、 have to put up. This is one of those things (whichthat) we have to put up with. 3)引导定语从句的关系副词有 when, where, why 等。关系副词在从句中作状语，意义上相当于一个“介词+which”的结构。 Even in comic books where (=in which) there are no words; the stories are fully expressed through the drawings. No one knows the reason why (=for whic
16、h) he was so angry that day.*非限制性定语从句 非限制性定语从句既可修饰先行词，也可修饰整个主句，起补充说明作用，与主句之间有逗号隔开，若省去，原句意思不受影响。不可用 that 引导非限制性定语从句。关系词不可省略。 Every object has a gravitational pull, which is rather like magnetism. *“介词+whichwhomwhose”引导的定语从句 “介词+whichwhomwhose”可引导限制性定语从句，也可引导非限制性定语从句，该结构中介词的选择取决于从句谓语动词的固定搭配，或先行词的习惯搭配。
17、 This is the computer on which he spent all his savings It is written by a person with whom we are all familiar. *as 引导的定语从句 as 引导的定语从句主要用于“ such.as”及“the same.as”的结构中，代替先行词是人或物的名词。as 引导非限制性定语从句时，代替整个主句，从句可位于主句之前、之后或中间。 These are not such problems as can be easily solved. (as 代替先行词 problems) As is m
18、entioned above, no single company or group can control what happens on the Internet.(as代替主语) 6.状语从句 *时间状语从句 引导时间状语从句的从属连词和词组有： 1）when, whenever, while, as, after, before, since, till, until, once 等。 We have learnt quite a lot about it since we came here. 2)as soon as, hardly(scarcely).when, no soone
19、r.than, each(every) time, the moment, immediately(that)等。 As soon as I sent an e-mail message, I received positive responses. The moment he heard the good news, he jumped with joy. *地点状语从句 引导地点状语从句的连词是 where, wherever. Wherever she went, she took her little daughter with her. *原因、结果和目的状语从句 1）引导原因状语从
20、句的从属连词有：because, as, since, now(that), seeing that, considering that ,in that 等。 Considering that he is a freshman, we must say he is doing well. 2)引导结果状语从句的连词有：so.that, such.that, so that, that,so 等。 Mickey Mouse is so attractive that the children are reluctant to leave. 3)引导目的状语从句的连词有：so that, in
21、order that, for fear that, lest 等，从句常使用 may, might, can, could, would 等情态动词。 We got up early this morning so that we could catch the first bus to the railway station. *条件和让步状语从句 1）引导条件状语从句的连词和词组有 if, unless, as(so) long as, on condition that, in case, provided(providing) that, supposing 等。 As long a
22、s you have the right equipment, you can use a telephone line to transmit computer data. 2)引导让步状语从句的连词和词组有 though, although, whether, even though, even if, no matter what (when, how.),whatever (whenever, wherever, however.)等。though, even if 等引导状语从句可转换成含有 as 的部分倒装结构，具有强调意义。其结构为“形容词（副词、动词、名词）+as+主语+ 谓语
23、” 。 No matter what you may say, I would not change my mind. Young as he is, he is quite experienced in this work.(=though he is young) (这个是倒装句,如果展开说又是长篇大论,你要学再慢慢说哈,不过写作文用个倒装句一下子又升 level 了 倒装句还有虚拟语气好加分的)Child as he is, he can speak English fluently.(=though he is a child) *方式状语从句 引导方式状语从句的连词有 as, just as, as if, as though 等。as if, as though 引导的状语从句中，谓语动词常用虚拟语气，表示与事实相反。 The young man made the experiment just as the teacher had taught him. Everything went on as usual as if nothing had happened.
