人教部编版初中英语最重要的3大从句考点总结
中考英语三大从句(宾语从句、状语从句、定语从句)
【中考英语专项复习——宾语从句】(一)宾语从句的种类宾语从句在句中作及物动词的宾语,或介词的宾语,或形容词的宾语。
根据引导宾语从句的不同连词,宾语从句可分为三类。
1. 由that引导的宾语从句。
that只有语法作用,没有实在的意义,在口语和非正式文体中可以省略。
例如:He said (that) he wanted to stay at home.She doesn’t know (that) she is seriously ill.I am sure (that) he will succeed.2. 由连接代词who, whom, whose, what, which和连接副词when, where, why, how引导的宾语从句。
这些连接代词和连接副词在宾语从句中充当某个成分。
例如:Do you know who (whom) they are waiting for?He asked whose handwriting was the best.Can you tell me where the No.3 bus stop is?I don’t know why the t rain is late.3. 由if或whether引导的宾语从句。
if和whether在句中的意思是“是否”。
例如:I want to know if (whether) he lives there.He asked me whether (if) I could help him.(二)宾语从句的语序宾语从句的语序应为陈述句的语序。
例如:I hear (that) physics isn’t easy.I think (that) you will like this school soon.Can you tell me how I can get to zoo?Please tell me when we’ll have the meeting.(三)宾语从句的时态1. 如果主句的时态是一般现在时,宾语从句该用什麽时态就用什麽时态。
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。

初中重要知识点归纳从句的种类与用法总结
初中重要知识点归纳从句的种类与用法总结从句是语句中的一个部分,由一个主语和一个谓语组成,无法独立存在,必须依附于一个主句才能完整表达意思。
根据它在句中的功能和结构,从句可以分为主语从句、宾语从句、表语从句、定语从句和状语从句等几种类型。
本文将对初中阶段重要的从句种类与用法进行总结。
一、主语从句主语从句在句中充当主语的角色,用来引出句子的主题或说明主句的内容。
例如:1. What he said is true.2. Whether she will come is still uncertain.二、宾语从句宾语从句在句中作为主句的宾语,具体说明主句的动作或状态。
例如:1. They asked me if I could help them.2. I know that he is a good student.三、表语从句表语从句在句中作为主语或宾语的补充,用来补充说明主语或宾语的特点、性质、状态等。
例如:1. The problem is whether we can solve it.2. His dream is to become a doctor.四、定语从句定语从句在句中作为主句中的名词的修饰语,用来对主句中的名词进行限定或修饰。
例如:1. The book that you lent me is very interesting.2. I like the girl whose hair is long and curly.五、状语从句状语从句在句中作为主句的一个状语成分,用来说明主句的时间、原因、目的、条件、方式等情况。
例如:1. I will go to the park if it doesn't rain tomorrow.2. Because I was sick, I couldn't attend the party.需要注意的是,从句的引导词会根据从句的类型和引导的具体内容而有所不同。
初中英语从句语法总结
初中英语从句汇总在英语中,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定语从句: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.1.先行词与关系词先行词就是被定语从句修饰的名词、代词等,它总是出现在定语从句的前面。
关系词指用来引导定语从句的词,分为关系代词和关系副词,关系代词在定语从句中作主语、宾语、表语、定语等,关系副词在定语从句中作状语。
1)关系代词2)关系副词1)判断哪一部分是先行词,先行词指人、物、时间还是原因The book which/that I left here just now is gone. 我刚才放在这里的书不见了。
(the book 是先行词,指物)I'll forever treasure the days which/that we spent on the seashore. 我将永远珍惜咱们在海滨一起度过的那些日子。
(the days, 指时间)2)确定关系词。
既要考虑先行词,又要考虑关系词在从句中充当的成分。
比较: I'll forever treasure the days which/that we spent on the seashore.我将永远珍惜咱们在海滨度过的那些日子。
(先行词是the days,指时间,在定语从句中作spent的宾语,因此选择关系代词which或that)I'll forever treasure the days when we played on the seashore.我将永远珍惜我们在海滨玩耍的那些日子。
初中从句知识点总结讲解
初中从句知识点总结讲解从句是指在一个复合句中,除了主句之外的句子,包括状语从句、名词性从句和定语从句。
在写作中,从句的运用可以使句子更加丰富多样,增加表达的灵活性。
在初中阶段,学生需要掌握从句的种类、引导词和用法,以便在写作和阅读中能够正确地理解和应用。
一、状语从句1. 引导词状语从句的引导词有很多,包括关系副词(when, where, while, before, after, since, until 等),以及连词(because, although, if, unless等)。
这些引导词可以帮助我们理解从句与主句之间的逻辑关系。
2. 用法状语从句用来修饰主句,表示时间、地点、条件、原因等。
例如:When I was young, I used to play in the park.(我小的时候,我常常在公园里玩。
)3. 注意事项状语从句的位置可以灵活变化,可以放在主句之前、之后或中间。
当状语从句放在主句之前时,从句后面要加逗号;而当状语从句放在主句之后时,则不需要逗号。
二、名词性从句1. 引导词名词性从句有三种类型:主语从句(that, whether, who, what)、宾语从句(that, whether, who, what)、表语从句(that, whether, who, what)。
这些引导词在句子中充当名词的角色,可以帮助我们扩展句子的意思。
2. 用法名词性从句可以充当主语、宾语和表语,用来代替一个名词或名词短语。
例如:What he said is true.(他说的是真的。
)3. 注意事项名词性从句通常由连接词that引导,但在口语中也可以省略that。
需要注意的是,在表语从句中,代词what在从句中充当表语而非名词。
三、定语从句1. 引导词定语从句的引导词包括关系代词(who, whom, whose, which, that)和关系副词(when, where, why)。
初中重点语法三大从句总结
初中重点语法三大从句总结初中的语法学习,很多同学觉得头疼得要命,不过别担心,今天我们来聊聊三大从句——宾语从句、定语从句和状语从句。
搞明白这几个小家伙,语法就没那么可怕了!1. 宾语从句1.1 什么是宾语从句?你有没有过这种体验:别人问你问题,而你又想用句子里的句子来回答?这种句子里嵌套了一个句子,这就是宾语从句。
简单来说,宾语从句就是充当动词宾语的句子。
它通常跟在动词后面,好像是“动词+宾语”这种结构的延伸。
1.2 例子和用法比如你听到有人问,“你知道她什么时候回来吗?”这句话中的“她什么时候回来”就是宾语从句。
再比如:“我不知道他什么时候到。
”这里的“他什么时候到”就是宾语从句,作为动词“知道”的宾语。
在实际使用中,宾语从句常见的引导词有“that”(虽然这个词在口语中常常省略)、“whether”(或“if”)以及各种疑问词(如“what”,“where”,“when”,“why”,“how”等)。
注意:在口语中,“that”通常可以省略,但在书面语中还是要用哦。
2. 定语从句2.1 什么是定语从句?定语从句是用来修饰名词或代词的,从而给它们添加更多信息。
你可以把它想象成一个超级详细的名片,它告诉你更多关于那个人或物的信息。
定语从句一般紧跟在它所修饰的名词或代词之后,就像给名词穿上了一个“定制的衣服”。
2.2 例子和用法比如说,“我认识那个会弹吉他的女孩。
”这里的“会弹吉他的”就是定语从句,它修饰了名词“女孩”。
常见的引导词有“who”(用于人)、“which”(用于物)、“whose”(表示所属关系)、“that”(可以指人或物)。
例如:“The book that I borrowed is very interesting.” 这句话中的“that I borrowed”就是定语从句,它修饰了名词“book”。
注意:“that”在定语从句中可以替代“who”或“which”,尤其是在非正式的语境中。
初中英语必会三大从句讲解
初中英语必会三大从句讲解1. 名词性从句(Noun Clauses)名词性从句用来在主句中充当名词的作用,有以下三种类型:a. 主语从句(Subject Clauses):主语从句用来作为主句中的主语,通常以连接词从属连词"that"引导,也可以用连接代词"what"、"whatever"、"whoever"、"which"等引导。
例如:-What you said at the meeting is very important.(你在会议上说的话很重要。
)b. 宾语从句(Object Clauses):宾语从句用来作为主句中的宾语,通常以连接词从属连词"that"引导,也可以用连接代词"what"、"whatever"、"whoever"、"which"等引导。
例如:-I believe that he will succeed.(我相信他会成功。
)-She doesn't know what she should do.(她不知道她应该做什么。
)c. 表语从句(Predicate Clauses):表语从句用来作为主句中的表语,通常以连接词从属连词"that"引导,也可以用连接代词"what"、"whatever"、"whoever"、"which"等引导。
例如:-Her dream is that she can travel around the world.(她的梦想是能够周游世界。
)2. 定语从句(Adjective Clauses)定语从句用来修饰或限制名词或代词,通常以关系代词"who"、"whom"、"which"、"whose"、"that"等引导。
人教部编版初中英语中考定语从句考点汇总
人教部编版初中英语中考定语从句考点汇总一、英语中的定语从句与汉语中的定语位置不同。
在复合句中,修饰某一名词或代词的从句叫做定语从句。
英语中的定语从句始终要放在被修饰的词之后,而汉语中的定语则放在被修饰词之前。
如:The man(先行词)who / that I saw at the school gate yesterday(定语从句)is my English teacher.昨天我在校门口看见的那个人是我的英语老师。
二、英语从句中的句型结构比较复杂,有先行词、关系代词或关系副词。
被定语从句修饰的词叫先行词,引导定语从句的关联词有关系代词或关系副词。
限制性关系分句和它的先行项的所指意义有着不可分割的联系。
关系代词或关系副词放在先行词和定语从句之间起纽带作用,关系代词或关系副词在定语从句中要充当一个成分。
关系代词在句中可作主语、宾语或定语,关系副词在句中作状语。
如:I am waiting for the boy (先行词)who /that (关系代词)is wearing a red coat. (主语)我正在等穿着红色外套的那个男孩。
The dictionary (先行词)that / which(关系代词)my sister gave me last Sunday is very expensive.(宾语)我姐姐上周星期天给我的那本字典很贵。
The woman is his mother (先行词)whose (关系代词)name is Linda Brown. (定语)那个是他的母亲,名叫琳达·布朗。
That is the house (先行词)where (关系副词)my father used to live.(状语)那是我父亲曾经居住过的房子。
三、初中英语中定语从句关系代词或关系副词的具体用法。
1. who指人(也可用that),在定语从句中作主语,也可作宾语。
如:Yesterday I helped an old man who / that lost his way. (主语)昨天我帮助了一位迷路的老人。
三大从句知识点总结
三大从句知识点总结一、名词性从句名词性从句是在句子中充当名词的作用,可以位于主句中的主语、宾语、表语或者介词宾语的位置,起着名词的作用,因此也被称为从句名词。
名词性从句主要包括宾语从句、主语从句、表语从句和同位语从句等几种。
1. 宾语从句宾语从句用来充当主句中的及物动词(transitive verb)或介词后面的宾语,例如:I know (that) he is coming.(我知道他要来了。
)He said (that) he would come tomorrow.(他说他明天会来。
)在上面的两个例句中,that引导的从句分别充当了know和said后面的宾语。
2. 主语从句主语从句用来作为整个主句的主语,例如:That he is so successful surprises everyone.(他这么成功让每个人都感到惊讶。
)What he is saying is true.(他所说的是真的。
)在上面的两个例句中,从句that he is so successful和what he is saying分别作为整个主句的主语。
3. 表语从句表语从句用来作为及物动词后的表语,例如:The problem is that we don't have enough time.(问题就在于我们没有足够的时间。
)在这个例句中,从句that we don't have enough time充当了动词is后的表语。
4. 同位语从句同位语从句用来解释或者说明名词的内容,例如:The news that he won the prize is exciting.(他获奖的消息令人兴奋。
)在这个例句中,从句that he won the prize充当了news这个名词的同位语。
名词性从句在句子中起着非常重要的作用,能够充分地承担名词的功能,并且丰富了句子的表达方式。
二、定语从句定语从句用来修饰名词或代词,对其进行进一步的说明或者限定,增加句子的信息量。

二、连接词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.三、时态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。
