句子基本是:简单陈述句,由简单陈述句转变成肯定句,否定句,疑问句。疑问句是用来提出问题。英语中有四种疑问句: 一般疑问句、特殊疑问句、选择疑问句和反意疑问句。我们现在已经接触到了前两种疑问句。后两种疑问句以后我们还会学到.
一.一般疑问句:
英语中要用 yes和no 来回答的疑问句叫一般疑问句。如:
1)Is it hot ?Yes, it is .No, it isn’t.—— be动词引导
2)Is it a car ?Yes, it is .No, it isn’t .—— be动词引导
3)Is this your ruler ?Yes, it is .No, it isn’t .—— be动词引导
4)Do you like bananas ?——含实义动词
Yes, I like bananas. No, I don’t like bananas.
5)Can Ming hear a drill ?——含情态动词
Yes , Ming can hear a drill.No,Ming can’t hear a drill.

二. 祈使句:表示请求、命令、建议或劝告等的句子叫祈使句,主语you常省略。
1、肯定形式:一般以动词原形开头。 Open the door, please.
2、否定形式:在句首谓语动词前加Don‘t。 Don‘t be late for class.
三特殊疑问句(又叫wh-question)
用特殊疑问词来提出问题的疑问句叫作特殊疑问句。特殊疑问词一般要放在句首。常用的疑问词有what who ,which how 等这些词都以wh开头(包括how)所以也叫作wh-question。特殊疑问句要求回答具体内容。不能用yes或no回答。结构:疑问词+一般疑问句。回答不能用yes / no(或相当于yes / no)回答的问句。答句的句式同肯定句句式:如:
What can you see ? I can see a cat.
What can you hear ? I can hear a bus.
What can you do ? I can sing and dance.
What is it ? It’s a panda.
What do you like ? I like playing football
How old are you ? I’m ten.
