★语法部分

学习目标：1. 学会正确使用and, but, or和so连词。

2. 学会正确使用both… and …, not only… but (also) …, either… or…和neither… nor… 关联词语。

在我们过去的英语学习过程中，我们经常碰到and, but, or和so连词，我们能够了解它们在句中的意思，今天我们在此想归纳它们的具体用法。

1. and

◇“和”，连接两个名词，代词或两个形容词等语法作用相同的词语。例如：The air was so warm and bright.

It has no eyes and no ears.

I have no sister or brother.

特别提醒：

①and如果用在否定句中，必须把and改成or。例如：

She can’t play badminton or table tennis.

He didn’t come or go to see a film with us.

②如果前后名词都用no修饰，则可以用and连接。例如：

I have no sister and no brother.

◇表示目的，意图。常用于go, come, stop, run, stay等动词后。例如：

Come and have a rest with us.

Stop and see what they’re doing.

◇“只要……就会……”“如果……那么……”，用于祈使句后，表示条件与结果的关系。例如：

Knock on the door, and it will be opened.

Come l ate again, and you’ll be fired.

2. but

◇ "但是"，“可是”，“而”，“却”的意思，常用作转折连词，表示前后两个内容不一样、不一致。例如：

The old lady can speak, but she can’t write.

He is in poor English, but he still keeps working hard on it.

特别提醒：

①but不与although/though (“虽然，尽管”)连用。

Though he is old, he works hard.

He is old, but he works hard.

②还可以用作介词，常有nothing but结构，表示“除了……之外”。

She did nothing but watch TV.

3. or

◇ or “或者”的意思，表示选择关系，常用来介绍一件事情的另一种可能性。例如：

She can be a doctor or a teacher in the future.

I will go swimming or go fishing this afternoon.

◇选择疑问句中用or, “还是”的意思。例如：

Do you like apples or pears?

Would you like tea or coffee?

◇“祈使句+or +陈述句”，“……，否则……”的意思。例如：

Hurry up, or you will be late.

Work hard, or you cannot pass this exam.

4. so

◇so用作连词时，主要用于表结果，意为“所以”，“因此”。例如：

It’s very cold, so you’d better wear a heavy coat.

Th e door was locked, so we couldn’t get in.

The class began at seven, so we should hurry up.

特别提醒：

“因为…所以…”不可以用because…so…结构，so不可以和because连用。例如：

错误：Because he was ill, so he couldn't come.

正确：Because he was ill, he couldn't come.

正确：He was ill, so he couldn't come.

参考答案：1—5 CDCAB

1. both … and …

◇“两者都”、“…和…都”的意思，用以说明或强调某一件事情、某一个人或某一状况与另一件事情、另一个人或另一状况相同。例如：

Both Li Ming and Wei Hua are good at English.

Our English teacher both speaks and writes French.

The food was both bad and tasted badly.

特别提醒：

b oth… and …, 连接两个成分作主语时，谓语总是用复数。例如：

Both she and I are good at English.

Both teaching and research teaching are not easy work.

2. not only… but (also) …

◇“不但…而且…”、“不仅…而且…”的意思，在句中用以连接两个主语、连接两个不同的谓语动词、连接两个不同的宾语、连接两个表语。例如：

Not only I but also my parents are fond of watching the film.

Not only Lucy but also Lily is good students in our school.

He not only has a car but also drives on his own

I not only know English but (also) Russian.

Shakespeare was not only a writer but (also) an actor

特别提醒：

①由于not only A but also B句式的重点在B上，在汉语的意思上等同于both…and …，但要与both… and …区别开来。例如：

Not only she but (also) her brother likes playing the piano.

Both he and she are going to see English teacher.

Not only our school but also his school attends the sports meeting.

=Both our school and his school attend the sports meeting.

②n ot only…but also…连接的两个谓语动词一般不重复，这与汉语不同。例如：正确：I know not only English but also Russian.

错误：I not only know English but also know Russian。

3. either… or …

◇e ither…or…, 意为“不是…就是…”、“或者…或者…”、“要么…要么…”，指either或or后连接的其中一个，常用以连接连两个名词或两个动词。例如：Either your teacher or your classmates were there.

You either come in or go out.

4. neither… nor ….

◇“既不也不”、“…和…都没有（不）…”的意思。在句中可用作主语、谓语、宾语或表语。例如：

Neither you nor he is able to finish the work in an hour.

She neither stayed at home nor went shopping.

We could choose to eat neither noodles nor rice.

She is neither clever nor hardworking.

※综上所述，除both…and…关联词语外，其他的三个关联词语的谓语动词都遵循就近原则，即谓语与nor… 、or… 、but also…后的名词词保持一致，这是考试中经常遇到的关键点所在。例如：

1.[2009甘肃兰州]______ Tom ______ Mary speaks good Chinese, so they can communicate with these Chinese students very well.

A. Neither; nor

B. Not only; but also

C. Both; and

D. Either; or
