英语中从句的连接词辨析
简单地说，英语复合句所涉及的三大从句为：名词性从句（包括主语从句、宾语从句、表语从句、同位语从句），形容词性从句（即定语从句），副词性从句（即状语从句）。
1. 引导名词性从句通常有三类词：一类是连接词that, whether, if；另一类是连接代词who, whom, whose, what, which 以及whoever, whomever, whoseever, whatever,whichever；还有一类是连接副词how, when, where, why。
2. 引导形容词性从句（即定语从句）通常有两类词：一类是关系代词that, which, who, whom, as, whose等；另一类是关系副词where, when, why。
3. 引导副词性从句（即状语从句）的叫从属连词。
不同作用的状语从句通常由不同的从属连词来引导。
如：(1) 引导时间状语从句的从属连词主要有when, while, as, whenever, before, after, since, until, till, as soon as, the moment, the minute, the second, the instant, immediately, directly, instantly, once等。
(2) 引导条件状语从句的从属连词主要有if, unless, as [so] long as, in case 等。
(3) 引导目的状语从句的从属连词主要有in order that, so that, in case, for fear等。
(4) 引导结果状语从句的从属连词主要有so that, so…that, such…that等。

高考英语语法专项-连词(详解与真题)
干近5年高考全国卷真题语法专项-连词（详解与真题）本考点是历年高考中经常考查的要点，主要考查并列连词如：and，but，or等，以及状语从句中的连词when，while，as，if，though等。

状语从句易错易混点剖析
状语从句易错易混点剖析在英语学习中，状语从句是一个非常重要的语法结构。
状语从句是指用来修饰主句中谓语动词的从句，通过对动词时态、语态、语气等方面的语法要求，来对主句的意思进行进一步的限定和说明。
但是在使用状语从句时，常常会存在易错易混的情况。
下面就来具体剖析一下容易错的点和混淆点。
易错点一、时态的误用在状语从句中，往往需要考虑时态的使用。
如果时态使用不恰当，就会影响到句子的意思。
比如，以下这句话：When he will come back to China, he will visit his parents.这句话的意思想必是想表达“他回到中国时，会去拜访他的父母。
”但是在语法上是不正确的。
因为在状语从句中，不应该使用将来时，而应该使用一般现在时态，所以这样写才是正确的：When he comes back to China, he will visit his parents.二、主句时态和从句时态的不一致在使用状语从句时，还需要考虑主句时态和从句时态的一致性问题。
如果主从句时态不一致，就会影响到句子的意思。
比如，以下这句话：After I finish my homework, I will go to sleep because I was very tired.这句话的意思想必是想表达“因为我很累，所以我会在完成作业后睡觉。
”但是在语法上是不正确的。
因为在状语从句中，应该使用现在完成时，而在主句中应该使用一般过去时，所以这样写才是正确的：After I have finished my homework, I will go to sleep because I am very tired.三、条件状语从句的使用错误条件状语从句是指用来表示情况、条件的从句，其中包括了真实条件和虚拟条件。
虚拟条件又分为与现在事实相反、与过去事实相反和与将来事实相反。
在使用条件状语从句时，还需要考虑虚拟语气的使用问题。

1．时间状语从句常见的从属连词有：(注意其汉语意义)2．when, while, as, before, after, since, until (till) once as soon as, the moment, the minute, immediately, directly, each/every time, the first time, the last time, next time, by the time, whenever等。
例如：3．Every/Each time I was in trouble, he would come to my help.4．I thought her nice and honest the first time I met her.注意：（1）when, while, as的区别：5．1)when引导从句时，主从句的动作有先有后，也可以同时进行,从句的动作可以是持续性的，也可以是短暂的。
如：6．When I got to the airport, the plane had already taken off. （主先从后）（短暂性）7．When I lived there, I used to go to the seaside on Sundays. (同时) （持续性）8．When the movie ended, the people went back. （从先主后）9．2)while侧重主从句动作的对比，且从句的动词必须是持续性的。
如：10．While we were chatting she was looking at the time table on the wall．11．3)as引导从句时侧重主从句动作同时或几乎同时进行，从句的动作可以是持续性的，也可以是短暂的。
如：12．Sometimes I watch TV as I am having breakfast．13．4）when和while还可以是并列连词，意思分别是“就在这时”，“然而”。
如：14．I was having a rest on the sofa when the telephone rang．15．They were surprised that a child should work out the problem while they couldn’t .注：并列连词when常用与以下句型中：①…was/were doing…when…（正在做…突然）②…was/were about to do…when…（刚要做…突然）③…was/were on the point of doing…when…(刚要做…突然)④…had just done…when….(刚一…就)⑤Hardly/Scarcely had…done…when…(刚一…就)(2)before引导从句时,词义非常灵活，注意下列句子中的before的词义：1.Before I could get in a word, the tailor had measured me.(还没来得及…就)2.We hadn’t run a mile before he felt tired.(还没…就)3.We had sailed 4 days before we saw land.(…才…)4.Please write it down before you forget it.(趁还…没就)(3)till (until) 和not…till (until)1） till (until):主句谓语动词必须是持续性的，意思是“到…为止“如：He remained there till/until she arrived.2）not…till (until)…: 主句谓语动词必须是短暂性的，意思是“直到…才”如：She won’t go to bed till/until he returns home.3）not…until还有强调式和倒装式：强调句：It is not until he returns home that she will go to bed.倒装句：Not until he returns home will she go to bed.(4)几个极易混淆的时间状语从句：1） It was +时间点+when…（当的时候时间是）It was 5 am when we arrived at the village.2） It was/will be+时间段+before…(没过…就／过了…才)It was/will be two weeks before we met/meet again.3） It is /has been +时间段+since…（自从…以来有…）It is/has been 3 years since we last met.突破点：一看be动词的时态，二看时间段还是时间点。
注意：在“It is /has been +时间段+since…”句型中，从句的动词必须是短暂性的，如果是延续性的动词，时间要从从句的动作结束时算起。
如：It is 3 years since I smoked.( 我戒烟有三年了)2．条件状语从句常见的从属连词有：if, unless, as/so long as , as/so far as, on condition that , in case(万一) , the more…, the more…等。
如：As/So far as I can see ( am concerned), it will be impossible for them to finish the task.The more books you read, the happier you will feel．(前面为从句)3．原因状语从句常见的从属连词有：because, since, now that , as等。
注意because, since, as的区别：１）why的语气最强，它引导的从句比主句更重要，从句的位置可前可后；例外回答why的问句必须使用because。
如：-Why were you absent from the meeting yesterday?-Because I was ill.2)since和now that意思是“既然”，语气仅次于because,从句的位置一般在前。
如：Since everybody is here, let’s begin our meeting．3)as的语气比since更弱，意思是“由于”，从句的位置可前可后。
如：As you didn’t turn up at yesterday’s get-together, we missed you very much．４）*for也有“因为”之意，但for是并列连词常用来来补充说明原因或用来表示推断的依据，前面常带逗号。
如：It must have rained last night, for the ground is wet．4．让步状语从句常见的从属连词有：though, although, as, even if / though, no matter wh-， wh-ever, whether…or…等。
如：However late/No matter how late he is, his family will wait for him to have dinner together.Child as he is, he knows a lot. (as引导的让步状语从句必须倒装)Whether it is fine or not, I will go boating．5．地点状语从句常见的从属连词有：*where, wherever等。
如：Put the book where it is．6．比较状语从句常见的从属连词有：*as…as, *not so (as)…as, *than等。
注意：(1)在表达倍数时，可用三种句型：1)A…＋倍数＋比较级＋than B 如：This building is twice taller than that one．2)A…＋倍数＋as原级as＋B 如：This building is three times as tall as that one．3)A…＋倍数＋the size(height, weight, length etc．) ＋of B 如：This building is three times the size of that one．(2) 三种句型变式：１）倍数＋more＋名词＋than２）*倍数＋as many/much ＋名词＋asAmericans eat more than twice as many vegetables per person today as they did in 1910.It is reported that the United States uses twice as much energy as the whole of Europe.7．方式状语从句常见的从属连词有：as , as if / though 等．注意：as if / though引导的从句常用虚拟语气，表示非真实情况．He talks about the moon as if he had been there．(从句动作先发生)She treated the boy as if he were/was her own child．(主从句动作同时发生) 8．目的状语从句常见的从属连词有：so that, that, in order that，in case (以免), for fear that等。
如：Most students go to college (so) that they can be engineers, teachers or chemists．注意：从句中的情态动词can, could, may, might等提示为目的状语从句．9．结果状语从句常见的从属连词有：so…that, such…that , so that等。
如：He earned so little money that he couldn’t support his family.It is such fine weather that we all want to go to the park.Tom studied very hard so that he passed the exam.三、用法灵活的as, when, while 引导的状语从句1. as可以引导时间、原因、让步、比较和方式等5种状语从句。
