考研英语语法： 学会辨认六类从句
考研英语语法：学会辨认六类从句说起英语，怎能忽视语法，单词背的再熟练，看完文章还是不懂含义，根源在于语法知识的匮乏。
中英文的语言思维模式并不相同，要想深入的学习考研英语，语法必不可少。
可是语法书那么厚，该怎么学呢?今天我们就来解读考研英语从句。
我们在阅读中，经常能够看到从句的身影，然而种类繁多的从句经常困扰着考生，使考生傻傻分不清眼中的从句究竟属于是哪一类从句，下面就对从句进行简单的剖析，希望对学生们的考研英语复习有所帮助。
►从句类型在英语中，经常使用的从句有以下六类：1.主语从句：一个句子在整个句子中充当主语的成分，该句子被称为主语从句。
2.宾语从句：一个句子在整个句子中充当宾语的成分，该句子被称为宾语从句。
3.表语从句：一个句子在整个句子中充当表语的成分，该句子被称为表语从句。

5.状语从句：一个句子在整个句子中充当状语的成分，该句子被称为状语从句。
6.同位语从句：一个句子在整个句子中充当同位语的成分，该句子被称为同位语从句。
►从句的辨认如果想辨认从句类型，学生们应该对从句的基本形式有所认识。
无论是哪种从句类型，在句子中充当成分的"句子"应该都具备以下特征：从句=从属连词+句子了解了从句的基本结构，那么应该如何辨别从句类型呢?学生可以在句子中通过简单的公式进行辨认。
常见的从句出现形式有四类：1.名词+从属连词+句子=定语从句/同位语从句2.动词+从属连词+句子=宾语从句/表语从句3.[从属连词+句子=状语从句]+句子4.从属连词+句子+动词=主语从句对于以上四类从句出现形式有了一定的了解，那么今天就首先看看第一类从句出现形式的辨认方法和注意事项吧!1.名词+从属连词+句子=定语从句/同位语从句文都教育教学研究院11例子1： Yet, being friendly is a virtue that many Americans value highly and expect from both neighbors and strangers.

初中英语语法——状语从句
状语从句一、考点解读今天我们复习状语从句，英语中状语与中文的状语大致相同，分为时间状语、地点状语、原因状语、目的状语、结果状语、条件状语、方式状语等等。
如果一个主从复合句中的从句是用来表示时间，原因等等时，那就称为状语从句。
在主从复合句中修饰主句中的动词、形容词、副词等的从句叫做状语从句，又由于其功能与副词非常相近，又称做副词性从句。
状语从句一般可分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、让步状语从句、比较状语从句和方式状语从句九种。
这节课我们主要复习如下的内容：1．时间状语从句2．地点状语从句3．原因状语从句4．目的状语从句5．结果状语从句6．条件状语从句7．让步状语从句8．比较状语从句9．方式状语从句二、专题梳理（一）时间状语从句在句子中起时间状语作用的句子称为时间状语从句。
时间状语从句可以放在句首、句中和句尾。
常用来引导时间状语从句的引导词有：when 当……时候while 当……时候as 当……时候、一边after 在……之后before 在……之前since 自从ever since 自从once 一……就……whenever 不管什么时候by the time 到……as long as 长达……as soon as 一……就……till/until 直到……1．when，while，as的用法从属连词when，while，as都可用来引导时间状语从句，意为“在……时候”。
但在具体用法上又不尽相同。
（1）这三个连词中，when用得最广，常可代替while与as。
与while相比，when引导的从句动词既可是延续性的，也可是终止性的。
as在这一点上与when相同，while所引导的从句中，动词只能是延续性的。
在初中阶段，我们几乎很少讲as引导时间状语从句。
是因为as在初中阶段是一种供了解性的内容。
e.g.When the fire broke out, all the studentswere sleeping soundly.（终止性的）当火灾发生时，所有的学生正在熟睡中。

高中英语2025届高考语法复习状语从句知识讲解
高考英语语法复习状语从句知识讲解一、概述常见的有although/though/even though引导的让步状语从句。
if/unless引导的条件状语从句。
until/when/while/as soon as引导的时间状语从句。
because引导的原因状语从句，so that引导的目的状语从句等。
if引导的条件状语从句和when引导的时间状语从句一般都会和时态相结合，即主要考查“主将从现”原则。
对于状语从句的学习可与专题六从属连词相结合。
在时间状语从句和条件状语从句中，主句和从句的时态一致问题一般有两种情况：（1）“主将从现”：主句用一般将来时，而从句用一般现在时。
常见的使用“主将从现”原则的连词有：表示时间的when, while, after, before, until, till, whenever, as soon as, as long as, once 等；表示条件的if, unless, so long as, in case等。
（2）“主祈从现”：若主句是祈使句，或主句中有情态动词时，那么从句用一般现在时表示将来。
（3）“主情从现”：若主句有情态动词, 那么从句用一般现在时表示将来。
如：You can get good grades if you study hard.如果你努力学习，你将取得好成绩。
状语从句由从属连词引导,与主句连接,位于句首时,常用逗号与主句分开,位于句末时,其前一般不用逗号。
状语从句根据其用途可分为时间状语从句、条件状语从句、原因状语从句、目的状语从句、结果状语从句、让步状语从句、比较状语从句、地点状语从句等。
二、时间状语从句(1)当主句是一般将来时态或祈使句,表示将来的意义时,从句通常用一般现在时,简称“主将从现”。
I’ll ring you up as soon as I get to Beijing.我一到北京就给你打电话。
(2) when引导的时间状语从句,通常表示主句和从句的动作同时发生;before表示主句的动作发生在从句的动作之前;after则表示主句的动作发生在从句的动作之后;as引导时间状语从句时,往往表示主句和从句的动作同时发生,不分先后。

e.g. Speak clearly, so that they may understand you.She has bought the book in order that she could follow the TV lessons.He left early in case he should miss the train.（五）结果状语从句结果状语从句是表示事态结果的从句，通常主句是原因，从句是结果。
由so that （从句谓语一般没有情态动词）, so … that, such … that等引导。
e.g. She was ill, so that she didn’t attend the meeting.He was so excited that he could not say a word.She is such a good teacher that everyone admires her.（六）条件状语从句条件状语从句分真实性（有可能实现的事情）与非真实性（条件与事实相反或者在说话者看来不大可能实现的事情）条件句。
引导条件状语从句的词（组）主要有if, unless, so (as) long as, on condition that, so (as) far as, if only ( = if )。
注意：条件从句中的if 不能用whether替换。
e.g. If he is not in the office, he must be out for lunch.You may borrow the book so long as you keep it clean.So far as I know（据我所知）, he will be away for three months.You can go swimming on condition that ( = if ) you don’t go too far away from the river bank.If he had come a few minutes earlier, he could have seen her.（七）让步状语从句让步状语从句可由although, though, as, even if (though), however, whatever, whether … or, no matter who (when, what, …)等引导。
注意：as引导的让步状语从句一般是倒装的。
e.g. Though he is a child, he knows a lot.Child as he is, he knows a lot.Whatever ( = No matter what ) you say, I’ll never change my mind.（八）方式状语从句方式状语从句常由as, as if (though), the way, rather than等引导。
e.g. You must do the exercise as I show you.He acted as if nothing had happened.（九）比较状语从句比较状语从句常用than, so (as) … as, the more … the more等引导。
e.g. I have made a lot more mistakes than you have.He smokes cigarettes as expensive as he can afford.The busier he is, the happier he feels.（十）使用状语从句时要注意的几个问题1、在时间和条件（有时也在方式、让步等）从句中，主句是一般将来时，从句通常用一般现在时表示将来。
e.g. We’ll go outing if it doesn’t rain tomorrow.I’ll write to you as soon as I get to Shangh ai.2、有些时间、地点、条件、方式或让步从句，如果从句的主语与主句主语一致（或虽不一致，是it），从句的谓语又包含动词be ，就可省略从句中的“主语+ be”部分。
e.g. When (he was) still a boy of ten, he had to work day and night.If (you are) asked you may come in.If (it is) necessary I’ll explain to you again.3、注意区分不同从句：引导的是什么从句，不仅要根据连词，还要根据句子结构和句意来判别。
以where为例，能引导多种从句。
e.g. You are to find it where you left it.（地点状语从句）Tell me the address where he lives.（定语从句，句中有先行词）I don’t know where he came from.（宾语从句）Where he has gone is not known yet.（主语从句）This place is where they once hid.（表语从句）练习、状语从句一、用横线划出下列句子中的状语从句，并指出是哪种状语从句：1.
