(错)Although he was weak, but he tried his best to do the work..(对)Although he was weak, yet he tried his best to do the work.从属连词

从属连词只能用来引导从句，而不能引导词或者词组。从属连词一般可以引导名词性从句和状语从句。

第一类引导名词性从句的从属连词

1）that 引导宾语从句或间接引语时，可省略。引导主语从句时不可以省略。

He said(that)he would come.宾语从句

His mother told me(that)he is a good boy.间接引语

That she is still alive is true.主语从句

2）if/whether 是否

I wonder if he is at home.I ask him whether he would come.注意：只可以用whether的情况

1.介词后面It will depend on whether it rains tomorrow.2.whether···or not 固定搭配Let me know whether you come or not.3.动词不定式前I don’t know whether to accept his advice.第二类引导状语从句的从属连词

词是延续性的动词）

as 当···I saw her as I was getting on the bus.till/until 直到I didn’t go to sleep until/till I finished my homework.as soon as 一···就··· As soon as he saw the policeman, the thief run away.2）连接地点状语从句的从属连词

where 在哪里There were lots of parks where I lived.3）连接原因状语从句的从属连词

because 原因,用于解释某事的原因，动机，强调直接原因和因果关系I do it because I like it.for 表因为，表间接的原因，用于说明，解释I soon went to sleep, for I was tired

since 表原因，比because弱，比as强，表一种已知的，显然的理由，常译为“既然as 表原因时，意义最弱 As you are in poor health, you should do more exercises

4）连接结果状语从句的从属连词

so···that···如此···以至于···He is so kind that everybody likes him.such···that···He is such a kind man that everybody likes him

5）连接目的状语从句的从属连词

1.D.考查“祈使句/名词+and+陈述句”句型。句意为：“再努力点，你就会成功的”。2.B.so(因此)是并列连词，引出一个表示结果的分句，前面应是一个表示原因的分句，而无需再用连词，排除A；C和D又不是句子，也错了。

3.D.因为rather than是对称连词，意为“而不”(from www.xiexiebang.com)。

4.A.因为but是并列连词，后面是个句子，前面也一定是个句子，而不是一个分词短语或不定式短语，更不能再用连词though，所以排除B、C和D。

5.C.考查“祈使句+and+陈述句”句型，意为“如果„就„”。虽然or也可用于此句型，但or是“否则、要不然”之意，如：Work hard, or you’ll fail.(努力学习，否则就会不及格。)6.D.因为not only„but(also)„是固定搭配(from www.xiexiebang.com)。

7.D.因为句中的并列连词for表示原因，是对前面分句所述内容的解释或补充说明。8.A.因为句中的并列连词while表示“对比或相反”。9.B.因为句中的并列连词when = just at that time, 意为“这时(突然)”。10.D.因为只有or才能表示选择，意为“(是„)还是”。

11.C。本题考查what引导主语从句，并在主语从句中作主语。句意为“在许多国家，所谓的“公立学校”并非公众拥有。

12.B。本题考查引导主语从句的连接词。that引导主语从句只起连接作用，在从句中不作任何成分，无意义，但不能省略。what除引导主语从句外, 还在从句中作成分。which指一定范围内的“哪一个”；whether意为“是否”。根据句意“世上的事喜忧交替”可知答案为B(from www.xiexiebang.com)。

13.D。该题考查宾语从句。可以看作是does it matter which book it was的省略。一定注意此题受母语干扰，很容易错选答案为A。只要抓住题干前一句I read about this story in some book or other的提示，就可知道是指一定范围内的“哪一个”，故答案为D。14.D。that引导同位语从句；what the book said是同位语从句中的主语。

15.A。本题考查以after引导的时间状语从句，意为“在„之后”。句意为“步行了六小时后，我累坏了”。

16.C。even if=even though,引导的让步状语从句，意为“即使, 尽管”，符合题意。17.D。本题考查before引导的时间状语从句，意为“在„„之前”。句意为“他来不及冲进去救他的孩子，屋顶就塌了”。18.C。When it comes to...是一固定句型，意为“当谈到„„时，涉及”。句意为“做作业是提高考分的一个可靠方法，这在涉及到课堂测验时尤其正确”(from www.xiexiebang.com)。19.B。该题考查where引导的地点状语从句，表示“在„地方”。句意为“我一直把照片放在我每天都能看到的地方，因为它总使我回想起大学里的日子”。20.B。so long as=so long as, 意为“只要”，表示条件。句意为“只要你答应归还，你就可以把这书借走”。

21.D。本题考查as引导的时间状语从句，表示事物的进展，意为“随着”。句意为“那人年纪越来越大，除了园艺外其他都不感兴趣”。22.A。once引导的让步状语从句，意为“一旦”。句意为“一旦明白了这条规则，就再也没有困难了”。

23.B。no sooner„than意为“刚„就”，相当于as soon as.句意为“我刚走回厨房,门铃又响了,响得足以把死人吵醒”。类似用法还有hardly / scarcely„when.。

24.A。本题考查because引导的原因状语从句及与for的区别。for不能跟not...but这一结构连用，句意为“我批评他不是因为我恨他而是因为我爱他”。

25.C。unless引导的条件状语从句。句意为“他如果不努力学习, 就永远不能考及格”。26.B。so that引导目的状语从句。句意为“她拼命干一边能在他回来时把一切都准备好”。27.D。until引导的时间状语从句。句意为“他一直等到火山平息下来,两天后他才得以重回火山上”。28.C。此题很容易错选B。误认为是not„until句型。实际上只要抓住your work is being done.这一提示就找到了答题的关键。

29.D。本题考查until引导的时间状语从句，意为“到...为止, 在...以前”。30.A。名词短语the moment用作连词，相当于as soon as,引导时间状语从句。意为“一„„就”。类似的短语或词还有the minute, the instance, directly, immediately等

第三篇：初中英语并列连词总结

并列连词

连词是一种虚词，它不能独立担任句子成分而只起连接词与词、短语与短语或句子与句子作用。连词主要分为两类：并列连词和从属连词。

并列连词表示单词、短语、从句或句子间有并列关系。分为：表平行或对等关系的连词、表转折关系的连词、表选择关系的连词、表因关系的连词

一、并列连词：

1.and “和” ；both…and…“……和……两个都” ；as well as“也”

not only…but also…“不但……而且……”;neither…nor…“既不……也不……” 例My mother bought me a present,and I like it very much.我妈妈买了一件礼物给我，我很喜欢He can speak not only English but also French.他会说英语还会说法语。

2.but“但是”；yet“然而”；while“而”；however“然而”

例： Lucy likes red while Lily likes white。露西喜欢红的，然而莉莉喜欢白的。

3.or“或者”；either…or…“要么……要么……”

注：由or 连接的句子可以转换为有否定条件构成的主从复合句。

Eg：Study hard，or you’ll fail the exam.=If you don’t study hard,you’ll fail the exam.努力学习，否则你考试会失败的。

Either you or he goes.“要么你去，要么他去”。

4.表因果关系的并列连词so “所以，因此”;for “因为”

Eg：Kate was ill so she didn’t go to school.凯特病了所以没去学校。

I have to stay up，for I have lots of homework to do。我必须熬夜，因为我有很多作业。

二、不能同时出现在一个句子中的连词。

1.because（因为),so（所以)不能同时出现在一个句子里，只能用其一.eg：Because he was tired,he couldn’t walk here.=He was tired,so he couldn’t walk there.因为他很累，所以走不到这里。

2.although/though（虽然），but（但是）不能同时出现在一个句子里，只能用其一。但although/though和 yet 可以同时出现在一个句子里（yet 用作副词）

Eg:Though he was tired,he still worked hard.=He was tired,but he still worked hard.：虽然他很累，但是她仍然坚持工作

三、and 和or 用于否定句中的区别

1)当列举成分是主语，又在否定词之前时用and连接；而当列举成分在否定词之后时，用“or”构成完全否定.Eg：I can’t sing or dance.我不会唱歌，也不会跳舞。

Lucy and lily can’t speak Chinese.露西和莉莉都不会说汉语。

在否定句中，如果所连接的两部分都有否定词那么用“and”而不用“or”

Eg：There is no water and no air on the moon.月球上没有水也没有空气。

2)在否定句中，without +and；而在肯定句中，without+or,构成完全否定。

Eg：Man can’t live without air and water=Man will die without air or water.五、由 either……or….., neither……nor……,not only……but also……连接两个并列主语时，谓语动词与较近的主语保持一致。（就近原则）

Not only my parents but also I am looking forward to meeting you.不止我父母，连我很也很想见到你。
