(完整版)初中英语从句语法讲解

从句从句按其在复合句中的作用,分为主语从句、表语从句、宾语从句、定语从句和状语从句等。

(参见以下各条)3、各从句在句子中的位置以及用法:(1) 表语从句:在句子中作连系动词的表语的从句,它位于主句中的系动词之后。

例如:That is why he did not come to school yesterday. / It is because you are so clever.(2) 宾语从句:在句子中作及物动词或介词的宾语。

①基本形式:(主句+)连词+从句主语+从句谓语+...②关于宾语从句连词的选择:若从句来源于一个陈述句,那么,连词用that,在口语中that可以省略;若从句来源于一个一般疑问句,连词则用if 或whether;若从句来源于一个特殊疑问句,则连词就是疑问词(如what,who,where,when等)例如:They believe that the computer will finally take the place of human beings.(他们相信计算机终将代替人类。

) (从句本来就是陈述句)/ I wonder whether I should saysomething for him to the headmaster. (我不知道是不是该为他在校长跟前说点什么。

) (从句来源于一般问句Shall I say something for him to the headmaster?)/ He asked mewhere he could get such medicine. (他问我在哪儿能搞到那样的药。

) (从句来源于特殊问句Where can he get such medicine? )③宾语从句的时态问题:如果主句是现在时,从句则用现在某一时态,甚至可以用过去时;如主句是过去时,从句则相应地使用过去某一时态,遇到客观真理时仍然用现在时。

如:I think Iwill do better in English this term. (我想本学期我的英语会学得好点。

初中从句知识点归纳

初中从句知识点归纳

初中从句知识点归纳一、宾语从句。

1. 定义。

- 在复合句中用作宾语的从句叫宾语从句。

例如:I think (that) he is a good student.(“he is a good student”就是宾语从句,作think的宾语)2. 引导词。

- that:无意义,在句中不作成分,可省略。

例如:He said (that) he would come.- if/whether:表示“是否”,在句中不作成分。

例如:I don't knowif/whether he will come.(注意:一般情况下,if和whether可以互换,但在句首、介词后、与or not连用时,常用whether)- 特殊疑问词(what, who, when, where, why, how等):在从句中作一定的成分。

例如:I don't know what he is doing.(what在从句中作宾语)3. 语序。

- 宾语从句要用陈述句语序,即“引导词+主语+谓语+其他成分”。

例如:Can you tell me where he lives?(而不是where does he live)4. 时态。

- 当主句是一般现在时,宾语从句可以根据实际情况使用任何时态。

例如:I know he is here now.(一般现在时);I know he was here yesterday.(一般过去时);I know he will be here tomorrow.(一般将来时)- 当主句是一般过去时,宾语从句要用相应的过去时态(一般过去时、过去进行时、过去将来时、过去完成时)。

例如:He said he was a student.(一般过去时);He said he was reading a book at that time.(过去进行时);He said he would come.(过去将来时);He said he had finished his homework.(过去完成时)- 当宾语从句表示客观事实或真理时,无论主句是什么时态,宾语从句都用一般现在时。

初中英语语法——三大从句汇总(重点笔记)

初中英语语法——三大从句汇总(重点笔记)

初中英语语法——三大从句汇总在英语中,主要有三大从句,即名词性从句(包括主语从句,宾语从句,表语从句,同位语从句)、形容词性从句(即定语从句)、副词性从句(即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等)。

以下是一些基本的从句的语法知识点A、定语从句专项讲解与训练一、定语从句概念定语从句(attributive clause),顾名思义,就是一个句子作定语从属于主句。

定语一般是由形容词充当,所以定语从句又称作形容词从句。

另外,定语从句是由关系代词或关系副词引导的,故又称作关系从句。

定语从句一般放在它所修饰的名词或代词之后,这种名词或代词被称作先行词。

请看示例:The woman who lives next door is a teacher.先行词定语从句在所有的从句中,算定语从句最难掌握,因为汉语里没有定语从句,汉语里只有定语,而且总是放在名词之前来修饰名词。

二、关系代词引导的定语从句关系代词代替前面的先行词,并且在定语从句中充当句子成分,可以作主语、宾语、定语等。

常见的关系代词有:who, that, which。

它们的主格、宾格和所有格如下表所示:先行词主格宾格所有格人 who whom whose物 which which whose of which人、物 that that —(一)关系代词who, whom和 whose的用法who代替人,是主格,在定语从句中作主语。

例如:An architect is a person who designs buildings. 建筑师是设计房屋的人。

I will never forget the teacher who taught us chemistry in the firstyear of my senior middle school.我将永远不会忘记在高一时教我们化学的那位老师。

Anyone who wants to apply for this job must send us the resume by email first. 想应聘这个职位的任何人都必须先通过电子邮件向我们发送简历。

1宾语从句在句子中起宾语作用的从句叫做宾语从句。

that: I think that you can pass the exam. Whether/if: I don’t know what the word means. “Wh”: I don’t know what the word means.I don’t know where he found the book.只用whether的情况:1. 与or not连用:I don’t know whether it’s raining or not.2. 与动词不定式连用:He doesn’t know whether to accept the invitation.3. 连接词前有介词时:It depends on whether he is coming.1. 主句是一般现在时态,从句根据实际情况而定(各种时态均可)She wants to know what he has done for the exam.2.主句是一般过去时态,从句用相应的过去的时态。

(精华版)初中英语语法基本从句汇总从句的共同特点
从句是指在一个句子中充当一个成分的句子,充当什么成分就叫什么从句,如:充当宾语就叫宾语从句,充当定语成分就叫定语从句。

从以上定义中我们可以得出关于从句的一个最大特点:从句是句子。

从句的共同特点:1.从句都有自己的连接词2.从句都是陈述语序(陈述语序就是主语在前,谓语在后,如:He is a teacher主语He在谓语is之前,因此是陈述语序,而Is he a teacher?主语He在谓语is之后,因此不是陈述语序。

)
1宾语从句
宾语从句是指在一个句子中充当宾语的句子,如:He said that he wanted to be a teacher when he grew up.
宾语从句的特点:
①宾语从句有自己的连接词
②宾语从句用陈述语序
③宾语从句的时态
①宾语从句的连接词:宾语从句的连接词包括that、if/whether(是否)、特殊疑问词。

②宾语从句的语序;
A.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
B.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.
③宾语从句的时态,只要记住以下口诀就可以了“主现则从任,主过则从过,客观真理一般现”
A.主现则从任:主句如果是一般现在时,则从句根据时间状语需要从八种时态中任选一种,如:1.He tells me he likes English very much(一般现在时)
B.主过则从过:主句如果是一般过去时,则从句根据时间状语需要从四种带“过”字的时态中任选一种,带“过”字的时态分别是如:一般过去时,过去进行时,过去将来时,过去完成时。

如:He told me that he liked playing football(一般过去时)
C.客观真理一般现:客观真理永远用一般现在时。

如:1.He says the moon goes around the earth.
2状语从句
2.1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。

举例:when当…的时候(一般情况下主句是将来时的时候,从句要用一般现在时。

)
Mozart started writing music when he was four years old.
2.2原因状语从句:在一个句子中作原因语的句子。

连接词:由连词because,since,as引导,也可由for,now that 等词引导。

2.5让步状语从句

定语是指在句子中用来修饰名词、代词的成分
如:I will give my teacher a bunch of beautiful flower.(中beautiful就是定语)
定语从句是指在一个句子中作定语的句子,定语从句要放在所修饰的词后
如:I have met the doctor who is in the No.1hospital.
定语从句的连接词:
连接代词:who、which、whom、whose、that
连接副词:when、where、why
5名词性从句
在句子中起名词作用的句子叫名词从句。

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
如:That she was chosen made us very happy.。
