例句:Do you like red ? Yes, I do ./ No I don’t .

Does your mother have a car ? Yes, she does./ No, she doesn’t.

(问句里面的划线部分用的是助动词does, 所以答句里面需要用does. 问句里面斜体部分your mother 相当于人称代词里面的she, 所以答句要用she )

Are there any grapes on the table ? Yes, there are ./ No, there aren’t.

(问句里面用的是be 动词 are , 所以答句里面用的也是are )

has/ have 所属有表示什么东西属于谁

We have five English books. 我们有五本英语书。(书属于我们的,所以用have )

He has a schoolbag. 他有一个书包。(书包属于他的,所以用has)

5.Any 和some 在句子里面的运用。

在一般疑问句中,表现一些的单词需要用any

在陈述句的肯定句里面表示一些的单词any 需要改为some。

在否定句里面,表示一些的单词,还是需要变为any 。

否定句指的是句子里面含有否定词的句子。

经常出现的否定词有以下这些:

aren’t = are not isn’t = is not don’t = do not

沪教N版三年级下册英语语法总结

3B 语法总结之一——CAN Hello, everyone! 我是can.我是一个情态动词,表示说话人的语气和情态,我没有人称和数的变化,在句子中不能单独作谓语,只能和紧挨着我的动词原形一起构成复合谓语。我的基本意思是“能;会”。OK,现在欢迎大家走进我的世界。 一、can的基本用法 1. 表示能力(如体力和脑力方面),意为“能;会”等。例如: Can you speak English? 你会讲英语吗? Can you play the piano? 你会弹钢琴吗? 2. 表示请求或允许,多用在口语中,意为"可以;能"等。用于疑问句中用来提出要求,用于否定句表示不允许。例如: Can I help you? 我能帮助你吗? You can’t play basketball. 你不能玩篮球。 Can you...?“请你……好吗?”表示说话人的请求;Can I...?“我可以……吗?”用来征求对方是否允许自己做某事。如在句末加上please一词就显得更有礼貌了。例如: Can you help me, please? 请你帮助我好吗? 二、can的句式变化如下: 1. 在变否定句时,直接在can后加上“not”,可缩写成can’t或cannot, 但不能写成cann’t.例如: He can swim. → He can’t swim. Emma can see the pen on the desk.→ Emma cannot see the pen on the desk. 2. 在变一般疑问句时,把can直接移到主语前(原主语的首字母改成小写,第一人称应变为第二人称)即可。例如: I can see an orange on the table. → Can you see an orange on the table? 其回答可用Yes, OK或Certainly等作肯定回答;用No或Sorry等作否定回答。例如: —Can you look after my books, please? 你能照看一下我的书吗? —OK. 可以。 用Certainly回答。此时语气更为肯定。例如: —Can I see your guitar? 我能看看你的吉它吗? —Certainly. 当然可以。 ----------------------
