高考英语复习连词

1、高考英语复习连词连词分为并列连词和从属连词两大类。并列连词是连接主语与主语，谓语与谓语， 句子与句子，分词与分词的词，它要求前后两部分有相同的形式和语法作用；而从属连词一般连接主句与从句，从句形式有名词性从句，定语从句和状语从句等。（一）并列连词：并列连词可用来连接词与词，词组与词组，分句与分句。常用的并列连词有：and（和），aswell as（既 又），bothand（不但 而且） ，not onlybut also（不但 而且） ，notbut（不是 而是），neithernor（既不 也不） ，eitheror（不是 就是） ，or（或者），but （但是），yet（然而），for（因

2、为），so（所以），while （而），when（这时）等。如： Both my brother and my sister are teachers./ His room is bright but mine is gloomy （暗沉沉的） ./ He can not only repair radios but also fix them./ It is a glorious （光荣的） yet difficult task./ Strike while iron is hot.（二）从属连词从属连词是指在复合句中引导从句的连结词。常见的从属连词有：引导时间状语从句的：after, be

3、fore, when, as, while, since, until, till, as soon as引导原因状语从句的：because, since, as引导让步状语从句的：although, though, no matter （无论） , even if (though)引导条件状语从句的： if, unless, once, so (as) long as引导结果状语从句的：sothat, suchthat引导目的状语从句的：so that, in order that引导比较状语从句的：asas, not so (as)as,than引导方式状语从句的：as if引导主语，宾语

4、或表语从句的连词主要有：that, whether, if 三个。其中that 和 whether 间或还可以引起同位从句和状语从句。（三）某些用法比较特殊的从属连词用法区别1、当 while, when, as引导时间状语从句时的区别： while 引导的状语从句中动词必须是持续性。谓语动词多为进行时，或状态动词的一般时。while的这些用法可用when 代替，等于“atthe time that” ,“ during the time。例that如： Please” keep quiet while (when) others are studying ；when除可指一段时间外，还可用来

5、指一点时间，等于“ at the time，也就”是说when引出的时间状语从句中的谓语动词可以是终止性的，也可以延续性的。 因此主句和从句的谓语可以是一般时，进行时，或完成时。例如： When I went into the lab, the teacher was doing an experiment. （ when 不能换成 while ） He often makes mistakes when he is speaking English. （ when 可换成 while ） as 常可与 when，while 通用，但强调“一边、一边”。例如：As (when, while)

6、I was walking down the street,I noticed a police car in front of number 37. when 引导的状语从句中的主语与主句主语一致，主、谓是“主语 +系动词” 结构时，这时主语和系动词可以省略。例如：When (he was) young, he workedfor a rich man./ She ll be here to give you help when (if it is) necessarywhen.件句，意为“如果” 、“假如”，例如： I ll come when (if) Im free.有时代替if ，引

7、导条2、 before作连词一般表示时间，意为“在 之前”，但有些句子中这样译就显得别扭。试看以下句子的翻译：He almost knocked me down before he saw me.他几乎把我撞倒才看见我；Before I could get in a word he had measured me. 我还 没来得及 插话，他已经给我量好了尺寸。3、 till,until作为介词式从属连词引导时间状语短语或状语从句，用于否定句时，结构为notuntil (till)，主句谓语动词延续与非延续皆可，意为“直到 才 ”。用于肯定句时，只与延续性动词连用，表示“到 为止”。例如：The

8、y played volleyball until (till) it got dark./ They didntalk（延续性动词） until (till) the interpreter （译员） came./ He didn t go to（bed非延续性动词）until(till) the his father came back. ；until 可以放在句首，till 则不行，例如：Until the last minute of thematch we kept on playing./ Not until he finished his work did he go home.

9、（倒装）；till, until只用于时间，以下句子是错误的：We walked till the edge of the forest. （要用 as far as或 to）。4、 because, since, as 引导原因状语时注意使用上的区别：如果原因构成句子的最主要部分 ,一般用because ,因此 because引导的从句往往放在句末。用why提问的句子，一定用because回答。 例如： He had to stay at home yesterday because he was ill.；如原因已为人们所知，或不如句子的其他部分重要，就用as，或since。since 比

10、as 更正式些。as 和since 引导的从句一般放在句子的开头。例如：As you are tired, you had better rest./ Si nce everyone is here, now lets begin.5、although和though引导让步状语从句往往用法一样，但注意以下区别： although用于各种文体， 而though则多用于非正式的口语或书面语中。注意由although, though引导的从句后，主句不能用but，但可用副词yet, still 。例如： Although/ Though it rained all the morning, they

11、 stillwent on working. （或 yet they went on working ） though 常与 even 连用， even though 表示强调，意为“即使”，但不能说 even although ，例如：Even though I didn t understand a word, I dept smiling. though 可用作副词，意为“然而” ，常用逗号与句子分开。 although 则不能这样使用，它只作连词。例如： It was a quiet party, I had a good time, though.6、once 作副词译 “曾经”，作

12、为连词译“一旦” ，引导条件状语从句。相当于if 的加强形式。例如：I don t believe he was once a thief. (once这里是副词 )/ Once Aristotle had made up his mind thatheavy objects always fell faster than light objects, he taught it as a truth to his students. (once连词 )7、unless 引导条件状语从句等于ifnot 。 例如：H e ll accept the job unless the salary is

13、 toolow. ( = He ll accept the job if the salary is not too low.)8、在用 as if 引导的方式状语从句及表语从句中，根据情况要使用虚拟语气。例如：He talksas if he knew all about it.但有时也可用直陈语气。例如：It looks as if it is going to rain.9、whether, if 引导从句的用法区别：引导主语从句、 表语从句或同位语从句时，用 whether ，不用 if 。例如： Whether they will go to the Great Wall is no

14、t known./ The question is whether we can finish the task on time./ The question whether we will take part in the physics contest has not been另外， as 做为关系代词还可以引导定语从句，如：decided. whether 可接不定式，而if 则不可。例如：I haven t decided whether to leave or not.whether 可作介词的宾语或置于句首表示强调，而 if 则不可。 例如： Everything depends

15、on whetherwe have enough money./ Whether he will come, I am not sure. whether 和 if 均可引导宾语从句，whether 引导的宾语从句一般都是肯定句， if 引导的宾语从句可以是肯定的， 也可以是否定的 （此时不能用 whether），例如： Could you tell us whether/ if it rains in winter in Australia?/ I wonder if itdoesn t rain.引导宾语从句的whether 和 if 常可与 or not 连用。连用时要注意or not

16、的位置， 它一般与whether、if分开使用，有时它可与whether合起来使用，但不能与if合起来使用。例如：I don t know whether/ if they will come or not./ I donher or not knowtheywillwhetcome. if可用来引导条件状语从句，译“如果”，whether 则不行。例如：If you work hard, you are sure to succeed.10、 as 作从属连词可引导多种状语从句。as 引导时间状语从句，意为“当 时”。例如：As (he was) a young man, he was a

17、storekeeper and later a postmaster./ He sang as he worked. as 引导方式状语从句，意为“象 一样” 。例如： We must do as the Party teaches us. as 引导原因状语从句。意为“由于”，例如： As you are tired, you had better rest. as 引导让步状语从句。意为“虽然” 、“尽管” Child as he is, he can do it well. ( = Although he is a child, he can do it well.)I have the
