初中英语语法之状语从句类型及考点讲义状语从句概念解析状语从句指句子用作状语时，起副词作用的句子，可以修饰谓语、非谓语动词、定语、状语或整个句子，可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句，是英语复合句学习的一个重点，在各类考试中都会经常出现，这次就来给大家讲解一下什么是状语从句。
1. 时间状语从句：常用引导词：when, as, while, as soon as, before, after, since , till, until特殊引导词：the minute, the moment, the second, every time, the day，the instant, immediately , directly, no sooner … than, hardly …when, scarcely … when instantlyI ran into the classroom as soon as the bell rang.2. 地点状语从句:常用引导词：where特殊引导词：wherever, anywhere, everywhereWherever the sea is , you will find seamen.3. 原因状语从句:常用引导词：because=in that, since=now that, as, for特殊引导词：seeing that, now that, in that, considering that, given thatI 'm late because I didn't caught the bus.4. 目的状语从句：常用引导词：so that, in order that特殊引导词： for fear that（唯恐/生怕），in the hope that, for the purpose that, to the end thatYou should book the hotel in advance so that the travel will be more easy.5.结果状语从句：常用引导词：so … that, such … that特殊引导词：such that, to the degree that, to the extent that, to such a degree thatHe is so young that he can't have meal by himself.6. 条件状语从句：常用引导词：if, unless,特殊引导词：as/so long as（只要）, only if, providing/provided that（倘若）, supposing that（倘若）, in case that（以防）, on condition thatYou can go to London as long as you have passport.7.让步状语从句：常用引导词：though, although, even if, even though特殊引导词： as(用在让步状语从句中必须要倒装)，while，no matter …， in spite of the fact that, whatever, whoever, wherever, whenever, however, whichever, as if=as thoughThough we are old, we still can do these by ourselves.8. 比较状语从句：常用引导词：as(同级比较), than(不同程度的比较)特殊引导词：the more …the more …; just as …，so…,no … more than; not A so much as BShe is as pretty as her mother.9. 方式状语从句：常用引导词：as, as if, how特殊引导词：the wayHe didn't so it the way his brother did.辨析：while，when，as三者引导的时间状语从句时间状语从句算是状语从句中最简单的一类，也是我们日常生活交流中最常用的一类，虽然难度不大，但引导词也不少，仍然有不少同学会弄混那几个常见引导词的用法，这次就为大家带来as，when，while这几个词的辨析方法，一起看看吧。
中考英语常考状语从句1.时间状语从句When/while/as, since, as soon as, until/till, before, after，once, by the time, the minute/ the moment(一...就...), every/each time, whenever,...(1) When & while &as①When:表示“当...时”，后面跟时间点、时间段均可，因而从句的动词可以是非延续性动词(又叫短暂性动词)或延续性动词。
例如：He was watching TV when his mom came back.当他妈妈回来时，他正在看电视。
When his mom was cooking, he was watching TV.当他妈妈做饭的时候，他正在看电视。
②While:表示“当..时”，后面只能跟时间段，因而从句的动词也只能是延续性动词，且常为进行时态（现在进行时或过去进行时）。
例如：While his mom was cooking, he was watching TV.当他妈妈做饭的时候，他正在看电视。
③as:表示“一边...一边...”【注意】与while区分：当一个人同时进行两个动作时(即主从句的主语是同一个人时)，只能用as。
还可表示“随着...”。
例如：Tom sings as he works. Tom一边唱歌一边工作。
As time went by, I learned how to be strong.随着时间的流逝，我学会了如何变得坚强。
(2) until & till (介词/连词)until:表示“直到...”，表示某个动作或状态一直持续到...为止。
例如：They waited until/till their mom came back.他们一直等到妈妈回来。
（主句谓语动词为延续性动词）“not...until”表示“直到...才”。

九年级中考英语语法讲解目的状语从句一、用to do sth表目的用不定式表目的是最简单也是最常用的方法，它既可以用于句末，也可用于句首，但比较而言，用于句首时，其强调意味较浓。
如：After missing a term through illness he had to work hard to catch up with the others.他因病一学期未上课，得努力赶上其他同学。
To avoid any delay please phone your order direct.为免延误, 请直接才丁电话预订。
To keep themselves awake they sat on the floor and told each other stories. 为了不至于睡着，他们坐在地板上轮流着讲故事。
To avoid back problems, always bend your knees when you lift heavy objects.为了不使背部受伤，你在扛重东西时，一定要将膝盖弯曲着。
不定式的否定式为not to do sth,而不是to not do sth。
如：She had to struggle not to give in to a desire to laugh.她极力控制自己不要笑出来。
Then there was the mad rush not to be late for school.然后就是匆忙往学校赶，以免迟到。

2023年初中英语语法之状语从句类型及用法一、时间状语从句1、when的用法(1)when既可引导一个持续性动作，也可引导一个短暂性动作，可用于表示主句和从句动作同时发生或从句动作先于主句动作，有时还可表示从句动作后于主句，意为“当、时候”( 2 ) when在be about to do、 when、 , be doing、 when、 , had done、 when、 , be onone' s way、when、，be on the point of doing、when、等结构中，作“那时突然”讲(3) when “既然、鉴于;尽管，虽然(位于主之后) ;如果2、while的用法( 1)表示“当、时候”，引导的动作必须是延续性的。
(2)用作并列连词，表示相对关系“然而”(3)引导让步状语从句，相当于although,意为“虽然”，位于主句前(4)引导条件状语从句，相当于as/so long as，意为“只要”3、as 的用法(1)表示“当、时候”，强调同时发生，不指先后。
(2)说明两种正在发展或变化的情况，表示“随着”，表示时间的推移(3)表示“一边、一边、(4)强调两个动作紧接着发生(5)表示“虽然，尽管”( 6)其他含义“正如，正像”"作为”，“由于，因为”4、before的用法(1)一般意为“在、之前”就"“还没有、"免得”"不知不觉”"宁可，宁愿”(2)It + will be/was + 时间段+before+一般现在时/一般过去时。
在肯定句中，意为“多长时间之后才” ;在否定句中，意为“用不了多长时间就”5、until和till(1)与肯定句连用，必须是延续性动词(2)与否定句连用，必须是非延续性动词，表示“直到、才，在、之前不、注意:not until可用于强调句和倒装句强调句 :t is/was not until...that...倒装:not until 放句首时，主要部分倒装6、since的用法(1)since后是非延续性动词，时间起点从该动作发生算起，意为“做某事多久了”; since后是延续性动词，时间起点从该动作结束算起，意为“不做某事已有多长时间”( 2)It is/has been +时间段+since+一般过去时7、表示“一、就、”的句型( 1) as soon as, once,immediately,directly,instantly,themomentthe minute等引导的从句都表示从句的动作一发生，主句的动作随即发生，常译作“一、就、”，这类从句中，经常用一般现在时态代替将来时态。
中考英语考点之 目的状语从句考点三十九 目的状语从句英语里可以用to ，in order to ，so as to ，so that ，in order that 来表示目的。
1. to ，in order to ，so as to 引导目的状语短语，构成简单句。
He has to earn lots of money in order to/to/so as to raise his family. 他赚很多钱是为了养家糊口。
2. so that ，in order that 引导目的状语从句，构成复合句，并且从句中谓语动词常与can ，could ，may ，might 等情态动词连用。
Speak clearly so that/in order to everybody can understand you. 请说清楚一点，这样每个人都能听得懂。
目的状语从句 结果状语从句 3. so thatso that 既可以引导目的状语从句又可以引导结果状语从句。
引导目的状语从句时译为＂为了＂，引导结果状语从句时可译为＂以便＂。
He workedn hard at his lessons so that he could gain high grades in the exams. 他努力学习功课，争取考试能获得好的成绩。
He workedn hard at his lessons, so that he gained high grades in the exams. 他努力学习，结果考试取得了好成绩。
so that 引导目的状语从句时，表示＂以便，为了＂，从句中常使用can ，could ，may ，might ，will ，would ，should 等情态动词或助动词；引导结果状语从句时，从句中一般不用can 和may 等词。
He has to earn so lots of muney so that he can buy his children nice food and clothes. 他必须赚很多钱才能给他的孩子提供好的饮食和衣服。
4. such...that...so that such...that...so...that... 结果状语从句在such...that...句型中，such修饰名词，意思是＂如此……以至于……＂，such...that...引导四种不同的句子结构。
（1）such+a(n)+形容词+单数名词+that从句This is such a good book that all of us like it very much.这是一本很好的书，我们大家都喜欢读它。
学&科网（2）such+形容词+复数名词+that从句They are such good students that the teacher likes them.他们都是很好的学生，老师喜欢他们。
（3）such+（形容词）+不可数名词+that从句It was such fime weather yesterday that we went swimming.昨天天气很好，我们去游泳了。
（4）one（no，any，all，many，some，several等）+such+可数名词+that从句There are many such good books that I can’t decide which one to choose.有这么多的好书，我无法决定选择哪一本。
5. so...that...so...that...句型中的so是副词，常用来修饰形容词或副词，意思是＂如此/这么……以至于……＂。
（1）常用句型：主语+谓语+so+adj./adv.+that从句The boy ran so fast that I couldn’t catch him.这个男孩跑得太快了以至于我追不上他。
（2）so+形容词+ a(n)+单数名词+that从句She made so good a meal that we all ate far too much.她做的饭菜那么好吃，结果我们都吃得太多了。
（3）so+many/much few/little（少）+名词+that从句当名词前有many、much、few、little（少）等词修饰时，句子中要用so...that...而不能用such...that...。
There was so little water in the jar that it was not enough for all of us.缸里的水太少了，不够我们这些人用。
注意：当little的意思是＂小＂时，仍用such...that...。
6. 用in order that引导：in order that的意思是＂为了＂。
He is working hard in order to pass the examination.=He is working hard in order that he can pass the examination.7. 用in case引导：in case此时的意思是＂以防＂＂以备＂。
I always keep a bottle of wine by in case friends call round.我平时总存着一瓶酒以备朋友来时喝。
注意：in case引导目的状语从句与引导条件状语从句时的意思不一样。
8. 在目的状语从句中也有这样一个引导词——in order that，容易与它混淆的词组是in order to，后者并不能引导状语从句。
下面看一下两者有哪些具体差别。
首先要注意的是，in order that与in order to译文相同，都译作＂为了……＂，不同之处在于：in order that+从句；in order to+动词原形。
in order that+从句构成目的状语从句，表明主句行为目的；in order to+动词原形构成目的状语，不成从句。
I get up early in order that I can catch the early bus.I get up early in order to catch the early bus.为了能赶上早班车，我很早就起床了。
He works hard in order that he can obtain a higher position.He works hard in order to obtain a higher position.为了升职，他很努力地工作。
另外，目的状语从句还有一个特点：由于目的都是未来的行为，所以从句中一般用表示未来可能性时态，当然还可以用will，would，can等。
He studies English very hard in order that he will go abroad one day.为了将来有一天能够出国，他很努力地学习英语。
in order that与in order to只是结构相似，含义相同，但两者用法却有较大差异，不能够互换使用，因为后者不能引导目的状语从句，只能跟动词原形构成目的状语。
