连词和并列句

并列句一、概念由两个或两个以上的简单句并列连接起来的句子称为并列句(compound sentence)。

并列句中的各个简单句彼此独立，互不依从，但它们表达的意思之间有一定的关系。

并列句中的各个简单句通常用并列连词连接起来。

并列连词之前可用逗号，也可不用逗号（但however、therefore、otherwise等并列连词前后都常有逗号）。

常见的并列句结构是：简单句+并列连词+简单句。

这种简单句常被叫做分句。

PS. 并列句是连词连接前后两个“互不依存的主谓结构”，两者是并列的关系；而状语从句中前后的两个句子一个是主句，一个是从句，从句是用来修饰主句的。

I help him and he helps me.This is our first lesson, so I don't know all your names.She likes bread and milk, but she doesn't like eggs at all.You can draw a good horse in five minutes, yet you kept me waiting for a year.Hurry up, or you'll be late.One was filled with kerosene（煤油）, one with castor oil（蓖麻油）and one with vinegar（醋）.二、并列连词并列连词可表示多种意义，但主要有四种，即表示并列、转折、选择、因果等。

1、表示并列关系的并列连词（1）并列连词and的用法①可以连接两个的词，多用于肯定句中。

Go and fetch something to eat.He started to shout and sing.Read it slowly and clearly.Proper diet and exercise are important to health.②连接两个句子，表示因果、对比、条件、假设、目的等。

They didn't catch the bus, and had to stay in a hotel for the night.（因果）Mary likes music and Lily is fond of sports.（对比）Work hard and you will succeed.（条件）（2）并列连词both…and, not only…but also, as well as的用法①both…and意为：“不但…而且…；既…又…”，并列主语时谓语动词用复数形式。

Both New York and London have traffic problems.The secretary both speaks and writes Spanish.Both teaching and research work are making great strides.She both plays the piano and sings.Both she and the headmaster were pleased with the boy.②not only…but also意为：“不但...而且”，是并列连词，可以连接两个词，也可连接两个句子。

其中，but also 中的also可以省略。

a.连接两个成分not only…but also可以连接句中所有的成分，连接并列主语时，其谓语动词根据就近原则，与所靠近的成分保持数的一致。

Not only the students but (also) their teacher is enjoying the movie.He can speak not only French but (also) English.He not only had seen the film but also remembered what he had seen.b.并列两个句子not only…but also可以连接两个句子，not only位于句首时，not only后的句子要倒装。

Not only is he a scientist, but he is also a fighter.Not only was evrything he had taken away, but his citizenship.③as well as,表示“同、和、也”等。

The editors as well as the proofreaders are working overtime.I have read his novels as well as his plays.我读过他的小说和剧本。

④neither…nor…，意为“既不……也不……”2、表示转折关系的并列连词这类连词连接两个含义不同的甚至是反义的词、短语或分句。

常见的还有yet(然而)，while(而)，however(可是)等。

其中while与but的区别在于:while表示对比，而but表示意义正好相反。

The changes in the city will cost quite a lot, but they will save us money in the long run.Excuse me for breaking in, but I have some news for you.He was in deep trouble , yet he didn't lose heart.Rick was very successful, however, the last few years of his life were not happy ones.You like sports, while I'd rather read.注意：not…but在连接主语时，谓语动词要按就近原则，与靠近的主语在人称和数上保持一致。

Not the manager but the workers are hoping to do that.Not you but I am a teacher.3、表示选择关系的并列连词此类并列连词主要有or, or else, either…or, otherwise，neither…nor, not nor等。

（1）or的用法①可以连接两个的词，多用于否定或者疑问句中。

主语的人称、数不一致时, 动词随着接近的主语而变化。

He never smokes or drinks.Will you have tea or coffee?Are you leavening for Beijing by train or by plane?She will be back either today or tomorrow.②连接两个句子，常和else连用。

Would you like a cup of coffee or shall we get down to business right away?Put on your overcoat, or you will catch cold.He must pay the debt or else go to prison.Hurry up, or/or else we'll be late for the meeting.注意：or, or else, otherwise三者相比，or else语气较or强，而otherwise语气则最强。

Make haste, or (else) you'll be late.Let's begin, otherwise, we will fall behind.I would like you to change this blouse, or else give me my money back.练习1. Tom______Mary cannot speak Chinese. They did not speak Japanese clearly_______correctly, either.2. The clock has no eyes____ears. And it has no mouth____ no legs, either.3.Man can’t live without air______water.

The situation at home abroad is in our favor.（2）either…or, neither…nor, not …nor的用法①可以连接两个的词either…or, neither…nor, not …nor等连接主语时，谓语动词也依据就近原则。

Either my father or my brothers are coming.Neither you nor I am wrong.Either the coach or the players are responsible for the defeat.He does not ride, nor shoot, nor fish .②连接两个句子，当neither, nor放句首时，该句倒装。

Either we go now or we remain here forever.Neither could theory do without practice, nor could practice do without theory.4、表示因果关系的并列连词这类连词常见的有so(因此)，for(因为)，therefore(因此)等。

并列连词for表示原因，用以附加说明。

这个词引导的分句必须放在第一个分句之后。

（1）for的用法for可以表示原因，但引起的不是从句，而是分句，对前面的情况加以解释，有逗号把它和前面的分句分开，在书面语中用的较多。
