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.

Yes， 主语+情态动词can/
No，主语+情态动词can+ not

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.
