八年级上册英语各单元知识点大归纳
Unit 1 Where did you go on vacation
一、语法通关
、不定代词：不指名代替任何特定名词或形容词的代词叫做不定代词。常见的不定代词有all , both ,each , some ; any ; many ; much ; few ; little ; one ; ones ; someone ; anyone ; something ; anything ; nothing...本单元我们主要区别some和any以及由它们组成的复合不定代词。
1、some 和any +可数名/不可数名.
some 多用于肯定句，any多用于否定句、疑问句和条件从句。当问话者希望得到对方肯定回答的时候，疑问句中也可以用some，不用any。例如：Hello , I’m a reporter. Can I ask you some questions 你好，我是一名记者，我可以问你一些问题吗？
由some ; any ; no ; every构成的复合不定代词作主语时，其谓语动词用第三人称单数。例如：No one wants to be fat.没有人想要长胖。
3、不定代词若有定语修饰，该定语要置于其后，例如：something interesting。又如：There is nothing interesting in today’s film. 今天的电影没有什么有趣之处。
、关于一般过去时。
肯定句：主语+was \ were +其它，例如：It was great.
主语+动词过去式+其它，例如：We went to the beach yesterday. 我们昨天去了沙滩。

主语+didn’t动词原形+其它，例如：We didn’t go to the beach yesterday. 我们昨天没去沙滩。
