1、英语从句类型总结(共9篇) ：从句 英语 类型 英语从句的类型与用法 英语从句的类型总结 英语八大从句类型总结 篇一：英语从句的分类 名词性从句是由if, whether, that 和各种疑问词充当连接词所引导的从句，其功同名词一样。 一主语从句 主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。 1. It 作形式主语和it引导强调句的比较 It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人是也可用who/w

2、hom。例如： It is a pity that you didnt go to see the film. It doesnt interest me whether you succeed or not. It is in the morning that the murder took place. It is John that broke the window. 2. 用it 作形式主语的结构 (1) It is 名词从句 It is a fact that 事实是 It is an honor that 非常荣幸 It is common knowledge that 是常识 (

3、2) it is 形容词从句 It is natural that 很自然 It is strange that 奇怪的是 (3) it is 不及物动词从句 It seems that 似乎 It happened that 碰巧 (4) it 过去分词从句 It is reported that 据报道 It has been proved that 已证实 3. 主语从句不可位于句首的五种情况 (1) if 引导的主语从句不可居于复合句句首。 (2) It is said , (reported) 结构中的主语从句不可提前。例如： It is said that President Ji

4、ngo will visit our school next week. (right) That President Jiang will visit our school next week is said. (wrong) (3) It happens, It occurs 结构中的主语从句不可提前。例如： It occurred to him that he failed in the examination. (right) That he failed in the examination occurred to him. (wrong) (4) It doesnt matter

5、how/whether 结构中的主语从句不可提前。例如： It doesnt matter whether he is wrong or not. (right) Whether he is wrong or not doesnt matter. (wrong) (5) 含主语从句的复合句是疑问句时，主语从句不可提前。例如： Is it likely that it will rain in the evening? (right) Is that will rain in the evening likely? (wrong) 4. What 与that 在引导主语从句时的区别 What 引

6、导主语从句时在句时在从句中充当句子成分，如主语宾语表语，而that 则不然。例如： 1) What you said yesterday is right. 2) That she is still alive is a consolation. 二宾语从句 宾语从句就是在复合句中作宾语的名词性从句，通常放在主句谓语动词（及物动词）或介词之后。 1. 作动词的宾语 (1) 由that引导的宾语从句（that 通常可以省略）,例如： I heard that be joined the army. (2) 由what, whether (if) 引导的宾语从句，例如： 1) She did no

7、t know what had happened. 2) I wonder whether you can change this note for me. (3) 动词间接宾语宾语从句。例如： She told me that she would accept my invitation. 2. 作介词的宾语 例如：Our success depends upon how well we can cooperate with one another. 3. 作形容词的宾语 例如：I am afraid (that) Ive made a mistake. That 引导的从句常跟在下列形容词

8、后作宾语： Anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content 等。也可以将此类词后的that 从句的看作原因状语从句。 4. It 可以作为形式宾语 It 不仅可以作为形式主语，还可以作为形式宾语而真正的宾语that 从句则放在句尾，特别是在带复合宾语的句子中。 例如： We heard it th

9、at she would get married next month. 5. 后边不能直接跟that 从句的动词 这类动词有Allow, refuse, let, like, cause, force, admire, condemn, celebrate, dislike, love, help, take, forgive等。这类词后可以用不定式或动名词作宾语，但不可以用that引导的宾语从句。例如： I admire their winning the match. (right) I admire that they won the match. (wrong) 6. 不可用that

10、从句作直接宾语的动词 有些动词不可用于“动词间接宾语that从句“结构中，常见的有Envy, order, accuse, refuse, impress, forgive, blame, denounce, advise, congratulate等。例如： He impressed the manager as an honest man. (right) He impressed the manager that he was an honest man. (wrong) 7. 否定的转移 若主句谓语动词为Think, consider, wuppose, believe, expect

11、, fancy, guess, imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式。例如： I dont think this dress fits you well.（我认为这件衣服不适合你穿。） 三表语从句 表语从句在复合句中作表语的名词性从句，放在系动词之后，一般结构是“主语连系动词表语从句”。可以接表语从句的连系动词有be, look, remain, seem等。引导表语从句的that常可省略。另外，常用的还有the reason is that 和It is because 等结构。例如： 1) The question is whet

12、her we can make good preparation in such a short time. 2) This is why we cant get the support of the people 3) But the fact remains that we are behind the other classes. 4) The reason he is late for school is that he missed the early bus. 四同位语从句 同位语从句就是在复合句中作名词的同位语的名词性从句。 1. 同位语从句的功能 同位语从句对于名词进一步解释，

13、说明名词的具体内容，一般由that引导，例如： 1) The kings decision that the prisoner would be set free surprised all the people. 2) The order that all the soldiers should stay still is given by the general. 2. 同位语在句子中的位置 同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。例如： He got the news from Mary that the sports meeting was put off. 3

14、. 同位语从句与定语从句的区别 (1) 定语从句中的that既代替先行词，同时以在从句中作某个成分（主语或宾语），而同位语从句中的that是连词，只起连接主句与从句的作用，不充当句中任何成分。 (2) 定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述定的性质或特征；同位语从句是名词性的，其功能是对名词进行补充说明。例如： 1) The news that he told me is that Tom would go abroad next year.（他告诉我的消息是汤姆明年将出国。）（第一个that引导的从句是定语从句，that在从句中作宾语） 2)The news tha

15、t Tom would go abroad is told by him.（汤姆将出国的消息是他讲的。）（同位语从句，that在句中不作任何成分）篇二：各种英语从句类型 各种从句类型 一、名词性从句 1、 主语从句： 定义：从句充当复合句的主语。 位置：从句位于句首；it（无意义）作形式主语放在句首，从句放在主句之后。 引导词：that，whether（连词） who，what，which，-ever（疑问代词/连接代词） when，where，how，why，-ever（疑问副词/连接副词） 练习：（1）从句位于句首 1.物价要上涨是明显的(go up) _ 2.派谁去还没有决定 _ 3.不

16、清楚她为什么那样做(clear) _ 4.你对我说的话很有用 _ (2)it作形式主语 5.很奇怪他对此一无所知 _ 6.碰巧那天她不在家（happen） _ *与强调句句型比较 1. It is clear that he loves singing. 2. It is in Shanghai that I saw the film. 二、宾语从句 定义：从句充当复合句中的宾语。 位置：在及物动词后（动宾结构）；在介词后（介宾结构）；it作形式宾语，从句放在主句后； 主语+be+表语（adj.）+宾从 引导词：that、whether、if（连词）；who，whose，what，which，

17、-ever（疑问代词/连接 代词）；when,where,how,why（疑问副词/连接副词） 练习： （1） 动宾、介宾结构 7.我们认为这是圈套。（圈套trick） _ 8.我会留意我是否能帮助你 _ 9.请跟我谈谈任何使你烦心的事（trouble） _ (2)it作形式宾语 10.我想当然地认为你会来(take it for granted) _ 11.我会很感激如果你把电视的音量调低（would appreciate it） _ (3)主语+be+表语（adj.）+宾从 12.我确信他会赢（be sure） _ 13.我肯定她看见我了(be certain) _三、表语从句 定义：从句

18、在复合句中充当表语。 位置：放在系动词之后 主语+系动词+表语从句 引导词：that、whether（在表从中不可用if表是否）、because、as if, as though（连词）who，what，which，-ever（疑问代词/连接代词） when，where，how，why，-ever（疑问副词/连接副词） 练习： 1.困难是我们缺乏资金(be short of) _ 2.问题是他是否能够我 _ 3.他缺课是因为他帮助老人（absent） _ 4.它看上去像是断了（broken） _ 5.这就是为什么你会成功 _ 四、同位语从句 定义：从句在复合句中充当同位语 位置：放在名词后，具

19、体说明名词的内容。这类名词为抽象性名词，含有内涵，如：fact,news, idea, truth, hope等。同位语与所修饰名词在内容为同一关系。 引导词：that、whether（连词） who，what，which，-ever（疑问代词/连接代词） when，where，how，why，-ever（疑问副词/连接副词） 练习： 1.他们获胜的消息传遍校园(spread) _ 2.他成功的事实证明了他的能力（prove） _ 3.我们将讨论会议能否举行（hold） _篇三：初中英语从句知识点总结归纳 宾语从句 一 定义：宾语从句是指在一个句子中充当宾语的句子 如：He said that

20、 he wanted to be a teacher when he grew up. 二 宾语从句有三种类型： 1由从属连词that引导的宾语从句表示陈述意义，连词that常可被省略。例如：I hope (that) they will have fun. Mary said that she felt sleepy. Cant you see (that) Im a bird? 注意：（1）当主句的谓语动词是think,believe等时，宾语从句尽管要表示否定意义，却不用否定形式，而将think等动词变为否定形式。如：I don“是否（有，能，已经?）”等一般疑问句的含义。 例如：I w

21、onder whether (if) he lives here. 3.由连接代词who,whom,whose,what,which和连接副词when,where,how,why等引导的宾语从句表示“谁，谁的，什么，哪（个，些），何时，何地，怎样，为什么”等等特殊疑问句的意义。除了连接词及被修饰的词提前以外，宾语从句用陈述句语序。 例如：To masked who could give the message to her mother. Do you know what he said just now? I wondered how old his brother was. 三.宾语从句的

22、时态呼应：“主现则从任，主过则从过，客观真理一般现” 1当主句是现在时或将来时的时候，宾语从句可以用所需要的任何时态。 2主句是过去时，宾语从句一般只能用过去时的某种形式；当从句叙述的是客观事实或一般真理时，宾语从句仍然用现在时态。 3情态动词must一般不用于过去时，但却可以用于主句是过去时的宾语从句中。 四.宾语从句的语序 1 宾语从句的连接词后加陈述语序（主语在前，谓语在后） 如：I want to know if he can come tomorrow 2 当连接词本身又是宾语从句的主语时，后面直接加谓语动词 如：She asked me who had helped him 状语从

23、句 英语中,修饰动词、形容词、副词等的句子成分叫状语。 状语的功用：状语说明地点、时间、原因、目的、结果、条件、方向、程度、方式和伴随状况等，根据状语的功能状语从句可分为：时间状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句。 一 时间状语从句：在一个句子中作时间状语的句子。 时间状语的连接词：when（当?时候） while（当?时候） as（当?时候） after（在?以后） before（在?以前） as soon as（一?就） since（自从?到现在） till /until（直到?才） by the time（到?为止）依旧是连接词后加陈述语序。 1. when

24、当?的时候（一般情况下：主将从现） I will become a teacher when I grow up 2. while 当?时 He visited a lot of places while he was traveling. 3. as 在?的同时；一边?一边? He smiled as he stood up. 4. after在?之后 He left the classroom after he had finished his homework the other day. 5. before 在?之前 Mr. Brown had worked in a bank for

25、 a year before he came here. 6. as soon as一?就?(一般情况下：主将从现) We began to work as soon as we got there. I will write to you as soon as I get home. 7. since 自?以来 到现在 表示自过去的一个起点时间到目前(说话时间)为止的一段持续时间。主句一般用现在完成时，从句用一般过去时。 Mr Green has taught in that school since he came to China three years ago. (还可以用作介词，本句

26、从句还可以用短语：since three years ago(自三年前以来)表示。) 8till /until直到 都可以作连词，连接时间状语，也可以作介词，与其它词构成介词短语，在句中作状语。 They walked till /until it was dark. Xiao Ming didnt leave home till / until his father came back. 9. by the time 到?为止 (所在句子的主句应用现在或过去完成时) By the time he gets there , his father has already gone. By the

27、 time I got to school, the class had already began. 用法辨析：1.when, while和as的区别 When 引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词。并且when有时表示“就在那时”。 例如： When she came in, I stopped eating. 她进来时，我在吃饭。(瞬时动词) When I lived in the countryside, I used to carry some water for him. 当的住在农村时，我常常为他担水。（延续性的动词） We were about to lea

28、ve when he came in.我们就要离开，就在那时他进来了。 While 引导的从句的谓语动作必须是延续性的，并强调主句和从句的动作同时发生（或者相对应）。并且while有时还可以表示对比。例如： While my wife was reading the newspaper, I was watching TV. I like playing football while you like playing basketball.我喜欢踢足球，而你喜欢打篮球。（对比） As 表示“一边?一边”，as引导的动作是延续性的动作，一般用于主句和从句动作同时发生；as也可以强调“一先一后。

29、例如： We always sing as we walk. 我们总是边走边唱。（as表示“一边?一边”） As we was going out, it began to snow. 当我们出门时，开始下雪了。（as强调句中两个动作紧接着先后发生，而不强调开始下雪的特定时间） as when while都表示主、从句动作同时发生，三者差异如下： as 表示“一边。一边的意思 when 1、还可以表示从句动词的动作在主几句动词的动作之前 或之后发生。 2、whenand then; at that moment (正在那个时候) 3.常用于常见搭配中 while 1、 用于时间较长时 2、 强

30、调两个动作同时进行，并表示对比时 有时这三个连词可以互换，有时不可以。 lt was raining hard when (as) I got there. 我到那里时，正在下大雨。 ( 动作同时发生，when可换为as, 但不能换为while，因为get是点动词.) When I had read the article, he called me. 我看完这篇文章之后，她给我打了 。( 从句动作发生在主句之前，注意时态表达，只能用when ) When I got to the cinema, the film had begun. (当)我到了电影院时，电影已经开演了。(从句的动作发生在

31、主句之后，只能用when,并要注意时态) He was about to leave, when the telephone rang. 他正要离开，忽然 响了。( 此时不能放在句首。主句动词一般表达 “正在” “即将”. while, as不能代替 She thought I was talking about her daughter, while, in fact, I was talking about my daughter. 他以为我在谈她女儿，然而，实际上在谈论我女儿。(表转折，对比，when, as都不能代替它) While the alien was buying a sou

32、venir, the girl called the police. 外星人买纪念品时，那女孩给警察打了 。(表示主句，从句的动作同时发生，while后引导的状语从句的动词必须是延续动词不能是点动词，因为它表示较长时间) Mother was worried because little Alice was ill, especially as (when/ while) father was away. 妈妈担心，因为小爱丽丝病了，特别是他父亲不在家的时候。(此时as ,when, while可通用) 2. 由till或until引导的时间状语从句。 till和until一般情况下两者可以互

33、换，但是在强调句型中多用until。并且要注意的是：如果主句中的谓语动词是瞬时动词时，必须用否定形式；如果主句中的谓语动词是延续性动词时，用肯定或否定形式都可以，但表达的意思不同。例如： I worked until he came back.我工作到他回来为止。 I didn't work until he came back.他回来我这才开始工作。 3. 由since引导的时间状语从句。 since引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词。一般情况下，从句谓语动词用一般过去时，而主句的谓语动词用现在完成时，表述为：现在完成时+since+一般过去时。但在It

34、 is 时间since从句的句型中，主句多用一般现在时。例如： It is five months since our boss was in Beijing.我们老板离开北京有五个月了。 知识扩展 1. It is since从.以来多长时间了 It is five years since we met last time. 2. It is +before?(。才。) It was a long time before I went to sleep again. It was an hour before(until) the police arrived. 二. 原因状语从句：在一个句

35、子中作时间状语的句子。 连接词：由连词because, since, as引导, 也可由for, now that 等词引导 1.I didnt go to school yesterday because I was ill. 2. Since everybody is here, lets begin our meeting. 既然。 3. As you are in poor health, you should not stay up late.既然。 4.I asked her to stay to tea, for I had something to tell her. .用法辨

36、析：because , since , as , for辨析 1）because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。 I didnt 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

37、 he is ill. He must be ill, for he is absent today. 三、 条件状语从句 连接词：if如果, unless (=if not)如果不、除非(让步) 1.If it doesnt rain tomorrow, we will go hiking. 2.I will go to the party unless he goes there too. 3.You will be late unless you leave immediately. =If you dont leave immediately, you will be late. 条件

38、状语从句：主将从现. He will not leave if it isnt fine tomorrow.四、 目的、结果状语从句 目的状语从句是指在一个句子中充当目的状语的句子。 结果状语从句是指在一个句子中充当结果状语的句子 目的状语从句连接词so that, so?that , in order that 引导。 结果状语从句连接词 so?that, such?that, so much/many?that引导。 1. so?that如此?以至于 He always studied so hard that he made great progress. 2. so that 以至于,

39、 以便于 Ill run slowly so that you can catch up with me. (目的) I opened the window so that fresh air might come in. (目的) 3. such?that如此?以至 Its such nice weather that all of us want to go to the park. 4. in order that=so that 为了 We shall let you know the details soon in order that you can/may make your a

40、rrangements. 5.比较：so和 such 其规律由so与such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 nice a flower such a nice flower so many / few flowers such nice flowers so many people such a lot of people （ so many 已成固定搭配，a lot of 虽相当于 many，但 a lot of 为名词性的，只能

41、用such搭配。） 难点 so+形容词或副词 so+形+a(an)+单数可数名词 so +many /few+复数可数名词 so +much/ little+不可数名词 so?that与such?that皆可引导目的地状语从句和结果状语从句。 The boy is so young that he cant go to school. He is such a young boy that he cant go to school so +adj/adv.+ that， such +n.+ that 以上两种句型都表示结果 so为副词,后接形容词，副词原型，可数名词前有many, few；不可

42、数名词前有much, little修饰时，应采用句型：so many (few, much, little )+n. such为形容词, 后只能接名词。这名词既可以地可数的，也可以是不可数的。如果这名词是可数的,则必须在名词前加不定冠词a(an). 常见的形式是:such a (beautiful)garden, such(nice)people. 五、 让步状语从句 让步状语从句是指在句子中作让步的状语的句子 连接词： though, although.，whether?or not 难点：though, although当“虽然”讲, 都不能和but连用. Although/though?

43、but的格式是不对的.但是他们都可以同yet (still) 连用. 所以thought (although)?篇四：初中英语三大从句 总结 一. 宾语从句object clause： 一. 定义definition： 在句子中起宾语作用的从句叫做宾语从句。 二. 连接词connections： that: I think that you can pass the exam. Whether/if: I dont know what the word means. “Wh”: I dont know what the word means. I dont know where he foun

44、d the book. 只用whether的情况： 1. 与or not连用： I dont know whether its raining or not. 2. 与动词不定式连用： He doesn“. 的” Eg. 1. Yesterday we bought a book which is really hard to understand. 2. The students who are from Maple Leaf School like learning English. Whom: 先行词指人，则代替先行词在定语从句中充当宾语（包括介词的宾语）, 与who的区别是如果前面带介

45、词则必须用whom 1. 2. I don Whose : 指人或物，作定语，表示 “的” eg: Harry is the boy whose mother is our math teacher.关系代词只能 that 的特殊情况: 1.先行词前有序数词修饰时： 2.先行词前有形容词最高级修饰时： 3. 先行词是不定代词something, anything等时. e.g. Is there anything that you want in this shop 4. 先行词是人和物时, 用that. e.g. He talked about some writers and books

46、that were unknown to us all. 5. 先行词被all , little , the only , the very(就是，正是), the last 等词修饰时,只 能用that e.g. This is the last place that I want to visit. 6. 特殊疑问句以who 或which 开头，只能用that引导. Who is the girl that is making a speech on the platform? 当关系代词前使用介词时： 物+介词+which ;人+ 介词 + whom 当关系代词前使用介词时： e.g.

47、1. This is the train by which we went to Beijing. 2. This is the teacher to whom my mother is talking. 三. 状语从句：Adverbial clauses 定义： 在复合句中由从句表示的状语称作状语从句，它可以用来修饰谓语（包括非谓 语动词）、定语或状语，或是整个句子。 状语从句一般分为八大类 时间状语从句地点状语从句 原因状语从句目的状语从句 结果状语从句条件状语从句 方式状语从句让步状语从句 1. 时间状语从句 When -当时候, 通常指某一特定的时间点，主句与从句的动作同时发 生。 W

48、hen - 正在的时候，突然。通常主句是进行时或 be about to 时， 在翻译的时候，when 可以译成没想到或突然。 When 当从句是进行时，主句是一般时，往往表示不满。 When=after While -在期间，往往指一段时间。While -表示一种不满情绪，意思是这边在干某种重要的事，而另一边在享受 等。 As - 一边一边, 随着 As - 当时，指一个动作紧接着一个动作发生，从句通常用进行时。 The moment - 一就 =as soon as , immediately, -Did you remember to give Mary the money you ow

Wherever - 无论哪里 4.原因状语从句 because, as, since, now that, 和considering that, seeing that 这六个连词都用于表示表示原因, 但在语气上一个比一个弱. Because - 因为,通常从句放在主句后.
