2020届中考英语语法专练连词及状语从句讲解及真题专练
状语从句一、状语从句的定义：状语从句是主从复合句中修饰主句中动词，形容词，副词等的从句，也叫做副词性从句。
状语从句一般分为时间、地点、条件、让步、比较、方式、目的、结果、原因九种状语从句附：各类状语从句连接词（短语）一览表：二. 时间状语从句：时间状语从句在主句中表示时间，常用连接词有：when（当……时），while（当……时），as（当……时），before（在……之前），after（在……之后），since（自从），not…until （直到……才）， as soon as（一……就），once（一旦……就）等。
1. 连词：(1) when引导时间状语从句，表示主句的动作和从句的动作同时或先后发生，从句的谓语可以是延续性动词，也可以是瞬间动词。
He was working when I went in. 我进去时他正在工作。
When she heard the news, she began to cry. 她听到这个消息，她哭了起来。
(3) while引导的状语从句中常用延续性动词或表示状态的动词，意思是“在……期间”。
while还可以表示两者之间的对比关系。
They rushed in while we were singing. 我们唱歌时，他们冲进来。
I like playing football, while Tom likes listening to music.我喜欢踢足球，而汤姆喜欢听音乐。
(4) as引导状语从句，强调同时发生，不分先后。
可以译成“随着”或“一边……一边”。
John sings as he walks home. 约翰一边往家走一边唱歌。
(5) since引导状语从句，主句常用现在完成时，从句常用一般过去时。
We have been friends since we met in Beijing.自从我们在北京遇到就一直是朋友。
It has been six years since she left school.自从她毕业已经有六年了。
译林版 中考复习 让步状语从句讲解+专练
译林版中考复习让步状语从句讲解+真题练习让步状语从句表示即便出现从句中的情况，主句动作仍然会发生。
引导让步状语从句的常用although /ɔːlˈðəʊ/、though/ðəʊ/、even though和even if。
although /ɔːlˈðəʊ/和though/ðəʊ/,意为“尽管……, 虽然...”，就是我们日常生活中用的“退一步说……”的感觉。
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，都可与yet, still或never 连用，但不能与but连用。
although常位于主句前，though位于主句前后均可。
I will try it although I may fail.Though he didn’t have much money, he was still happy.Although /Though it was only eight o’ clock, there were few people in the streets. Although/Though he was tired, (still) he kept on working.even though，意为“即使……”，是以从句的内容为先决条件的，即说话人肯定了从句的事实，表示已经发生了的事。
（一般过去时）Even though it was raining yesterday, we didn’t cancel our meeting.The famers still worked even though it was raining at that moment.even if，意为“哪怕…/就算…”，含有强烈的假定性，可用来表示与事实相反的假设，但不能用来描述已经发生的事实。
(一般将来时)Even if it rains tomorrow, we won’t cancel our meeting.因为含有强烈的假定性，所以有时还可以虚拟语气。

中考专项复习之连词讲解及练习
教师：杨立平学生：时间年月日中考英语语法连词语法讲解及练习（一）连词概述连词是连接单词、短语或句子的一种虚词。
在句中不单独作句子成分。
历年中考中常考并列连词and，but，neither…nor；从属连词now that，though，when。
所以了解状语从句和宾语从句的真正意义有助于正确使用从属连词。
（二）基础知识梳理1．并列连词用来连接彼此并列的词、短语或句子。
并列连词有and，or，but，so，for，nor等。
2．关联连词有both…and，either…or，neither…nor，not only…but also，as well as，as much as等。
3．连接性副词有however，therefore，besides，yet，anyway，still，all the same等。
4．并列连词和连接性副词存在以下的区别：1)连接两个独立的分句时，并列连词的位置只能放在它所引导的分句的句首，前面通常有逗号。
如：I must work hard, for I still have a long way to go.They all went, but I didn't go.2)连接性副词的位置比较灵活，句中、句首、句末都可以。
但是放在句首较为普遍。
如：Mother was ill, therefore, she stayed at home yesterday.= Mother was ill, she therefore, stayed at home yesterday.= Mother was ill, she stayed at home yesterday, therefore.3)两个并列连词不可以连用。
如：He tried hard．and but he failed to get the job.此句中的but应改为yet。
因为and和but 都是连词。

2.注意事项：(1) 时间状语从句中，一般要用一般现在时代替一般将来时，一般过去时代替过去将来时。
例如：I will telephone you when he comes. 他来时，我会给你打电话。
I’ll stay here until you come back. 我会呆在这里，直到你回来。
（2）引导词while, when, as的区别：1）when既可以指“时间点”,与瞬间动词连用，也可以指“时间段”，与延续性动词连用（=while）。
如：When he came in, his mother was cooking.When (While) we were at school, we went to the library every day.While表示时间段,因此，while 从句的谓语动词要用延续性动词。
如：Please don’t talk so loud while others are working.2）As与when用法相似，但着重强调主句动作与从句动作同时发生，有“随着……”或“一边……一边……”之意。
如：As you get older, you get more knowledge.随着年龄的增长，你获得的知识就越多。
三．地点状语从句：地点状语从句在主句中表示地点。
其连接词有where（哪里），wherever（无论哪里）等。
例如：Put it where you find it. 把它放在原来的地方。
You can sit wherever you like. 你喜欢坐在哪里就坐在哪里。
四. 原因状语从句：原因状语从句在主句中表示原因或者理由。
其连接词有：because（因为），as （因为），since （既然）等。
1.连词(1) because表示因果关系语气最强，常用来回答why提出的问题。
I didn’t tell them because they were too young.我没有告诉他们，因为他们太小。
（2）since 引导的原因状语从句，表示众所周知的原因，翻译为：既然，由于Since you come, wait for more time please.2.注意事项：（1.） because、since,as 语气强弱比较：because >since>as(2) because和so不能同在一个句子里。
Because the book was expensive, I didn’t buy it. (I 前不用so)五. 结果状语从句：结果状语从句在主句中表示结果。
其连接词有：so…that…（如此……以至于……），su ch… that…（如此……以至于……）等。
注意：(1) such... thatsuch＋a(an)＋形容词＋单数可数名词＋that从句such＋形容词＋复数名词/不可数名词＋that从句(2) so ... thatso＋形容词／副词.＋that从句so＋形容词＋a(an)＋单数可数名词＋that从句so+many/much/little/few +名词+that +从句He runs so fast that nobody can catch up with him.This was such a good film that I went to see it several times.It was such good books that they sell well.It was such bad weather that I had to stay at home.He spoke so fast that I couldn’t follow him.He is such a lovely boy that we all like him.=He is so lovely a boy that we all like him.六、. 目的状语从句：目的状语从句在主句中表示目的。
其连接词有：so（以便），so that（为了），in order that （为了）等，从句中多用情态动词can, will, may, should 等。
例如：He got up very early so that he could catch the first train.他起床很早以便于赶第一班火车。
I will run slowly so that you can catch up with me.我慢慢跑以便你能赶上我。
七. 条件状语从句：条件状语从句在主句中表示条件。
其连接词有：if（如果），unless （如果不，除非），as long as（只要）等。
例如：If it is fine tomorrow, we will go swimming.如果明天天气好的话我们去游泳。
注意：在条件状语从句中，一般要用一般现在时代替一般将来时，一般过去时代替过去将来时。
例如：Unless it rains, the game will be played.（= If it doesn’t rain, the game will be played.）如果不下雨，比赛就将进行。
As long as you tell truth , I’ll try to help you.只要你说出真相，我就尽力帮助你。
八让步状语从句：常由though/although (虽然)，even if/ though (即使)等引导，但though/although不能和but同时出现在一个句子里。
例如：Though it’s hard work, I enjoy it.（= It’s hard work, but I enjoy it.）尽管这是一件艰苦的工作，但我乐意做。
Though/Although it was raining，we went there.虽然下着雨，但我们还是去了那儿。
She won’t leave the TV set even though /even if supper’s on the table.即使晚饭已摆在桌上，她也不愿意离开电视机。
