七年级上册英语让步状语从句知识点：期末考试复习学好知识就需要平时的积累。

知识积累越多，掌握越熟练，编辑了七年级上册英语让步状语从句知识点：期末考试复习，欢迎参考! 所谓让步，就是我们日常生活中“退一步说……”的意思，有一种转折关系在里面。

引导让步状语从句的连词主要有以下这些：though, although,while, as; even if, even though; whether...or...; no matter+疑问词，疑问词-ever，一般翻译为“尽管……”或“即使……”，“无论……”。

用法如下： 1、though, although表示“虽然，纵然”之意。

这两个连词意思大致相同，在一般情况下可以互换使用。

在口语中，though较常使用，although比though 正式，二者都可与yet，still或never，the less连用，但不能与but连用。

例如： Although/Though he is very old, (yet) he is quite strong. 他虽然年纪大了，身体还很健壮。

 值得注意的是，although引导的让步状语从句位于主句之前的情况较多，though引导的让步状语从句可位于主句之前或主句之后。

 2、as，though表示“虽然……但是”，“纵使……”之意。

as引导的让步状语从句必须以部分倒装的形式出现，被倒装的部分可以是表语、状语或动词原形，though也可用于这样的结构中，但although不可以这样用。

例如： Hard as/ though he works, he makes little progress. (=Though he works hard, he makes little progress.)尽管他学习很努力，但几乎没取得什幺进步。

 3、even if, even though 表示“即使……”，“纵使……”之意，含有一种假设。

初一七年级英语语法定语从句用法总结含练习及答案定语从句是一种形容词的关系从句，由关系代词或关系副词引导。

初一英语中的定语从句仅限于限制性定语从句。

一、英语中的定语从句的位置。

英语中的定语从句始终要放在被修饰的词之后。

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。
