1、连词 连词是一种虚词，用于连接词与词或句与句，不单独用作句子成分。连词按其性质可分为并列连词和从属连词。一、并列连词1、表示并列关系的并列连词有：and, neithernor, not onlybut (also), bothand, as well as Eg:Neither you nor I am right. 你和我都不正确。 Not only my father but also I am interested in football. 不仅我爸爸而且我也对足球感兴趣。 Both she and Sophia were pleased with the girl. 她和索菲娅都对这

2、女孩满意。 Tom as well as I walks to school every day. 除了我，汤姆也每天步行去上学。2、并列连词的作用（1）表转折关系表示转折关系的并列连词有：but, yet, while, howeverEg：I failed again, but I wont give up. 我又失败了，但我不会放弃的。 I was born in Dalian while I grew up in Canada. 我在大连出生而在加拿大长大。（2）表因果关系表示因果关系的并列连词有so, therefore, forEg：I got up late, so I didn

3、t catch the early bus. 我起床晚了，所以没赶上早班车。 The days get longer, for it is already July. 天变长了，因为已经是七月了。（3）表选择关系表示选择关系的并列连词有or, eitheror，otherwiseEg：Work hard, or you will fall behind. 努力学习，否则你会落后的。Either you or he is going to do some shopping this afternoon. 今天下午或者你或者他去购物。注意：(1)bothand意为“和”，连接两个成分作主语时，谓语

4、动词要用复数。(2)neithernor意为“既不也不”；not onlybut (also)意为 “不但而且”；eitheror意为“或者或者”。它们连接两个成分作主语时，谓语的数通常与靠近其的主语的数保持一致，即遵循“就近原则”。(3)as well as意为“而且，还，又”，它连接并列主语时，谓语动词应与它前面的主语一致and : 表对等 “和、并且” but: 表转折 “但是”so: 表因果 “所以”3. 练一练A、1. I failed again, _ I wont give up. A. and B. but C. so2. This is my first lesson, _

5、I dont know your names. A. and B. but C. soor: 1. 用于疑问句, 表选择 2. 用于否定句, 表并列（肯定句用and）B、1. Which do you like better, apples, _ pears? A. and B. but C. or2. Now we have no time _ money. A. so B. and C. or3.Christine, Aileen _ (和) I are good friends. Study hard, _ (否则)youll fall behind. 4. Are you coming

6、 by bus _(或者) on foot? and 和 or 都可以在祈使句中使用. and 通常是比较好的结果;or 则表示不愉快或不理想的结果. C、1. Try your best _ youll make more progress. A. and B. but C. or2. Dont lose heart, _ youll lose all. A. and B. so C. oradj.比 + and + adj.比 表示越来越D、1. Its getting warmer _ warmer. A. and B. but C. orA or B 和 not A but B 结构作

7、主语时，谓语动词要使用就近原则。2. He or the twins _ the USA. A. comes from B. come from C. is from3. Not Tom but I _ going to give the talk.although 和but 不能同时出现。 A. am B. is C. areE、1. Although I have passed the exam, _ I am not pleased with the result. A. and B. but C. /F、So的特殊用法1、“so+情态动词/助动词/be动词+主语”句型为倒装结构，意思为

8、“也是如此”，系动词、情态动词或助动词必须与上句中的谓语动词保持时态的一致。Eg：-I like reading novels when I am free.有空闲时我喜欢读小说。-So do I.我也是。2、“so+主语+情态动词/助动词/be动词” 表示对上文所说的情况加以肯定。意思为“确实如此”。Eg：-He works hard.他工作努力。-So he does, and so does his brother.他确实是这样，他兄弟也是如此。G、eitheror；neithernor；not onlybut also就近原则1.

18、 want to.2) 如果原因已被人们所知，或不如句子的其它部分重要，就用as或since。since比as稍微正式一点。as和since 引导的从句一般放在句子的开头。例如：As he wasnt ready, we left without him.Since I have no money, I cant buy any food.3) for用来补充说明一种理由，因此，for引导的从句几乎可以放在括号里。for引导的句子不放在句子的开头。例如：I decided to stop and have lunch，for I was feeling quite hungry.三、引导宾语从

19、句的从属连词1that引导陈述句作宾语从句Eg：He told me that he would move to Japan the next year. 他告诉我第二年他将搬到日本。2if/whether引导一般疑问句作宾语从句。 Eg：I dont know if/whether there will be a bus any more. 我不知道是否还会有公交车。3wh疑问词引导特殊疑问句作宾语从句。如：Eg：He didnt tell me when we should meet again. 他没有告诉我我们什么时候会再见面。注意：(1)that无实际意义，可省略。(2)if/whe

20、ther 意为“是否”。(3)if/whether以及wh疑问词引导的宾语从句需要用陈述句语序。4、练一练A、when，while，as用法比较三者均可译为“在时候”。when引导的从句，动词既可以是延续性的，也可以是终止性的。一般来说，当主句的动作正在进行时，when引导的从句的动作才发生；while引导的从句中，动词只能是延续性的，一般来说，当while引导的从句的动作正在进行时，主句的动作才发生；若主从句动作同时发生，且强调“一边一边”这样的意思，一般用 as。 When I came into the room, I found him lying there asleep. She

21、sang as she walked. 她一边走一边唱歌。注意：while 可以表示对比关系“然而”。He is short while his brother is tall.B、if, whetherif和whether都可作“是否”讲，在引导宾语从句是一般可互换。例如：I wonder whether (if) you still study in that school.在下列情况下，只能用whether,不能用if：.在不定式前。例如：I havent made up my mind whether to go there or not.用or并列两项以上时。例如：I dont no

22、w whether he comes or not.从句作介词宾语时只用whether不用if。It depends on whether it will be fine.那得看是不是晴天。.作discuss等动词的宾语时，用whether不用if。We discussed whether we should close the shop.我们讨论是不是该关掉商店C、sothat, such.that1) sothat中的so是个副词，其后只能跟形容词或副词，而such.that中的such是个形容词，后接名词或名词短语。例如：Im so tired that I cant walk any farther.It was such a warm day that he went swimming.2) 如果在名词之前有many, much, little, few时，用so,不用such。例如：He has so little education that he is unable to get a job.
