状语从句和定语从句的用法区别

状语从句和定语从句的用法区别状语从句和定语从句是英语语法中常见的两种从句类型。
它们在句子中起到修饰作用,但使用方式和修饰对象有所不同。
在下文中,将详细介绍状语从句和定语从句的用法区别,并举例说明。
状语从句是一种修饰主句中动词、形容词或副词的从句。
状语从句在句子中作状语,用来说明动作发生的时间、原因、条件、方式等。
状语从句通常由连词引导,如when, while, after, before, as, since, if, unless等。
举个例子:- When I was young, I used to play soccer.(当我年轻的时候,我经常踢足球。
)这个例子中,状语从句"When I was young"修饰了主句中的动词"used to play",说明了动作发生的时间。
定语从句是一种修饰主句中名词或代词的从句。
定语从句在句子中作定语,用来对名词或代词进行进一步的描述、限制或说明。
定语从句通常由关系代词(that, which, who, whom, whose)或关系副词(when, where, why)引导。
举个例子:- The book that I borrowed from the library was very interesting.(我从图书馆借的那本书非常有趣。
)这个例子中,定语从句"that I borrowed from the library"修饰了主句中的名词"book",对其进行了进一步的说明。
状语从句和定语从句的区别主要体现在以下几个方面:1. 功能不同:- 状语从句用来表示动作发生的时间、原因、条件、方式等,对主句中的动词、形容词或副词进行修饰;- 定语从句用来对主句中的名词或代词进行描述、限制或说明。
2. 引导词不同:- 状语从句由连词引导,如when, while, after, before, as, since, if, unless等;- 定语从句由关系代词或关系副词引导,如that, which, who, whom, whose, when, where, why等。

初中英语重点语法三大从句总结

初中英语重点语法三大从句总结初中英语中,主要有三大从句,即宾语从句、定语从句、状语从句(包括时间、条件、结果、目的、原因、让步、地点、方式等)。
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。
1)She said that she was a student.2)She said that she would fly to Japan in a week. 3)She said that she had finished her homework already.3. 如果宾语从句说的是客观真理、自然现象或事实时,这时宾语从句要用一般现在时态。
The teacher said that the earth goes round the sun.2定语从句在复合句中修饰名词、代词的从句叫定语从句。
先行词指人 who /that先行词指物 which/ that定语从句一般紧跟被修饰的名词或代词(即先行词)后关系代词代替先行词在句子中担当成分,所以从句中不可再出现其他代替先行词的代词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词则必须用whom1. This is the teacher whomwho we like best.2. I don’t like the boy to whom you are talking.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:This is the first gift that my parents bought me.2.先行词前有形容词最高级修饰时:This is the most exciting film that I have ever seen.3. 先行词是不定代词something, anything等时.e.g. Is there anything that you want i n this shop4. 先行词是人和物时, 用that.e.g.He talked about some writers and books 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thate.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. 1. This is the train by which we went to Beijing.2. This is the teacher to whom my mother is talking.3状语从句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。
