九年级上册英语Unit1 grammar知识讲解和练习-译林版(含答案)
9A Unit1 Know yourself★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。
