初中英语语法从句

初中英语语法从句English:A subordinate clause, also known as a dependent clause, is a groupof words that has both a subject and a verb but cannot stand aloneas a complete sentence. It needs to be attached to an independent clause in order to make sense. Subordinate clauses can function as adverbs, adjectives, or nouns in a sentence. For example, in the sentence "When I finish my homework, I will go outside," the subordinate clause "When I finish my homework" acts as an adverb, providing information about when the main action will take place. There are different types of subordinate clauses, including adverbial clauses, relative clauses, and noun clauses, each serving different functions in a sentence. Understanding how to use subordinate clauses correctly can greatly improve the complexity and fluency of your English writing and speaking.中文翻译:一个从句,也被称为依存从句,是一个有主语和动词但不能独立成句的词组。

(精华版)初中英语语法基本从句汇总

(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 tomorrowB.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。

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。

初中英语语法:宾语从句

初中英语语法:宾语从句

初中英语语法:宾语从句宾语从句是一个从属从句,起到宾语的作用。

它通常紧跟在及物动词、介词、形容词或名词后面,承担宾语的功能。

宾语从句可以由连接词引导,如that, if, whether等等。

一、连接词that引导的宾语从句连接词that引导的宾语从句主要有以下几种用法:1. 在动词后面的宾语从句例如:I think that he is a good person.我认为他是个好人。

2. 在介词后面的宾语从句例如:I'm worried about whether I can pass the exam.我担心我是否能够通过考试。

3. 在名词后面的宾语从句例如:I have no idea where he is.我不知道他在哪里。

需要注意的是,连接词that在宾语从句中可以省略,特别是在口语中更常见。

例如:I hope (that) you can come to my birthday party.我希望你能来参加我的生日派对。

二、连接词if或whether引导的宾语从句连接词if或whether引导的宾语从句通常用于表示选择、疑问或不确定的情况。

1. 表示选择的宾语从句例如:He asked if/whether I wanted tea or coffee.他问我是要茶还是咖啡。

2. 表示疑问的宾语从句例如:I don't know if/whether she will come to the party.我不知道她是否会来参加派对。

3. 表示不确定的宾语从句例如:Do you know if/whether it will rain tomorrow?你知道明天会下雨吗?需要注意的是,在宾语从句中,if和whether可以互换使用。

但是在某些情况下,只能使用whether。

例如:I wonder whether you have finished your homework.我想知道你是否完成了作业。

初中英语语法讲解--名词性从句、形容词性从句、副词性从句三大从句讲解

初中英语语法讲解:名词性从句、形容词性从句、副词性从句一、名词性从句1. 概念名词性从句是指在句子中起名词作用的从句,包括主语从句、宾语从句、表语从句和同位语从句。

2. 搭配与用法主语从句:作为句子的主语,通常使用连接词that(无实际意义,不可省略)或whether/if(表示选择,不可省略)引导。

例句:That he will come to the party remains uncertain.(他是否会来参加聚会还不确定。

)宾语从句:作为动词或介词的宾语,可以由that、if/whether、特殊疑问词等引导。

例句:I don't know if he will come.(我不知道他是否会来。

)表语从句:作为连系动词的表语,通常由that引导,但that通常可以省略。

例句:The fact is that he didn't come.(事实是,他没来。

)同位语从句:用于解释说明前面的名词,通常由that引导,但that不可省略。

例句:The news that he resigned was a surprise.(他辞职的消息是个惊喜。

)3. 注意事项宾语从句中,当主句的谓语动词是think、believe、expect、suppose等表示心理活动的动词时,如果宾语从句表示的是事实,则宾语从句的否定通常要转移到主句上来表达。

例句:I don't think he will come.(我认为他不会来。

)在名词性从句中,一般不使用疑问句语序,而是使用陈述句语序。

例句:Can you tell me how I can get to the park?(请告诉我如何去公园?)而不是Can you tell me how can I get to the park?二、形容词性从句(定语从句)1. 概念形容词性从句,也称为定语从句,用于修饰或限定一个名词或代词,描述这个名词或代词的性质或特征。

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。

关系词常有3个作用:1,引导定语从句。

2,代替先行词。

3,在定语从句中担当一个成分。

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:格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1)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 first year 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。

2)whom代替人,是宾格,在定语从句作宾语,在非正式英语常可省略。

例如:Do you know the gentleman whom we met in the school library yesterday? 昨天我们在学校图书馆里遇到的那位先生你认识吗?This is the student whom my father taught ten years ago. 这是我爸爸十年前教的学生。

The girl who I saw is called Mary. 我见到的那个女孩名叫玛丽。

(在非正式英语中,主格who代替了宾格whom,亦可省略)3)whose一般代替人,有时亦可代替物,是所有格,在定语从句作定语。

例如:The girl student whose father is a senior engineer used to study abroad.其父是一位高级工程师的那个女学生过去在国外留学。

Do you know the name of the hotel whose window we can see here? 我们这儿能看到窗户的那个宾馆叫什么名字,你知道吗?(关系代词whose指代先行词hotel,正式用法应该用of which。

whose window=the window of which,意思是:the window of the hotel。

)(二)关系代词which的用法which代替物,在定语从句作主语或宾语,作宾语时还可省略。

例如:I do not like stories which have unhappy endings.我不喜欢有不幸结局的小说。

(which可以换成that)Tom works for a factory which makes watches.汤姆在一个制表厂工作。

(which可以换成that)(三)关系代词that的用法that既可指人又可指物,在当代英语中大多指物,在定语从句作主语或宾语,作宾语时还可省略。

例如:Is she the girl that sells newspapers?她是卖报纸的那个女孩吗?(that可以换成who)Where is the ice-cream that was in the fridge?放在冰箱的冰激凌哪儿去了?(that可以换成which)Is this the book that you want to buy?这是你要买的那本书吗?(that可以换成which,在定语从句作宾语,还可以省略)三.介词+关系代词引导的定语从句关系代词在定语从句中做介词宾语时,从句常由介词+关系代词引导(1) the school (that/which) he once studied in is very famous.(2) the school in which he once studied is very famous.(3) tomorrow i will bring here a magazine (that/which) you asked for.(4) tomorrow i will bring here a magazine for which you asked.(5) we'll go to hear the famous singer (whom/that/who) we have often talked about.(6) we'll go to hear the famous singer about whom we have often talked.注意:1. 含有介词的动词短语一般不拆开使用,如:look for, look after, take care of等(1) this is the watch which/that i am looking for. (t)(2) this is the watch for which i am looking. (f)2. 若介词放在关系代词前,关系代词指人时用whom,不可用who或者that;指物时用which,不能用that;关系代词是所有格时用whose(1) the man with whom you talked is my friend. (t)(2) the man who/that you talked with is my friend. (f)(3) the plane in which we flew to canada is very comfortable. (t)(4) the plane in that we flew in to canada is very comfortable. (f)3.“介词+关系代词”前可有some, any, none, both, all, neither, most, each, few等代词或者数词(1) he loved his parents deeply, both of whom are very kind to him.(2) in the basket there are quite many apples, some of which have gonebad.(3) there are forty students in our class in all, most of whom are from big cities.解答"介词+关系代词"类型的定语从句题时,关键在于分析定语从句中的谓语动词(该动词是不及物动词)习惯上常与什么介词搭配使用。

这就需要同学们在平时学习时要注重某些不及物动词和介词惯用的情形,并要灵活运用。

例如:in the dark street, there wasn't a single person ________ she could turn for help.a. thatb. whoc. from whomd. to whom简析:本题定语从句中的turn 与介词to 构成固定短语"turn to sb. for help (向某人求助)"。

所以,d是正确选项。

四、关系副词引导的定语从句常用的关系副词只有三个:when, where, why,在定语从句中充当时间、地点和原因状语。

它们的用法大家不妨记住一个口诀:the time whenthe place wherethe reason why(一)关系副词when的用法关系副词when代替的先行词表示的是时间,when在定语从句作时间状语。

例如:In Beijing July and August are the months when it rains very often.北京的七月和八月是常下雨的月份。

(when先行词是months)Do you remember the day when we first went to the Summer Palace?你还记得我们第一次去颐和园的那一天吗?(when先行词是day,当代英语里when可以用that替代,这时关系代词that就变成了表示时间的关系副词)I haven’t seen her since the year when I left Tokyo.自从我离开东京的那一年我就一直没见到过她。

(when先行词是year,同样when可以用that代替)(二)关系副词where的用法关系副词where代替的先行词表示的是地点,where在定语从句作地点状语。

例如:During the Spring Festival I went back to the town where I was brought up. 春节期间,我回到了生我养我的家乡。

(where的先行词是town)This is the place where Li Bai once lived.这是李白曾经生活过的地方。

(where先行词是place)上面这个句子不可以将where改为that,因为that不能作为表示地点的关系副词。

试比较下句:This is the place that Li Bai once visited.这是李白曾经游览过的地方。
