英语句子用法问题

你的意思是不懂一般疑问句和特殊疑问句的结构.
变一般疑问句：
有be动词的：Be+主语+其它?
没be动词的：Do/Does/Did+主语+动词原形+其它?
有情态动词的: 情态动词+主语+动词原形+其它?
1.I watched TV last night.--------Did you watch TV last night?（一般过去时）
2.I watch TV every day.----------Do you watch TV every day?（一般现在时）
3.He watches TV every day.----Does he watch TV every day?（一般现在时）
4.I am watching TV now. -------Are you watching TV now? （现在进行时）
5.He is watching TV now.-------Is he watching TV now?（现在进行时）
6.He is going to watch TV tomorrow.-----Is he going to watch TV tomorrow?(一般将来时）
7.He will watch TV tomorrow.-----Will he watch TV tomorrow? (一般将来时）
8. They can fly in the sky. ------ Can they fly in the sky?
a.句中有be动词的,直接把be动词放到句首就行了.如第5,6句.
b.句中没有be动词就看动词的形式.动词是原型就放Do 到前面.动词加了s/es就放Does到前面.动词是过去式就放Did到前面.注意放了do,does,did 到前面后,后面的动词要用原型.如1,2,3句
c.如果句中有情态动词(如：can, must,may,will, would, should,shall等等）就把情态动词放到前
面.如第7,8句.
编成几句话就是： 要变一般疑问句,be动词到前面去, 没有情态be动词,我们求助
do,does,did,前面用了do,does,did,后面动词用原形.
特殊疑问句： 疑问词+一般疑问句
1. 有be动词的： 疑问词+be+主语+其它如：What is he doing now?
Where are the children?
2. 没有be动词的：疑问词+do/does/did+主语+动词原形+其它?
如：When do you watch TV every day?
Where does she dance every day?
What did you eat yesterday?
3. 有情态动词的：疑问词+情态动词+主语+动词原形+其它?
如：What can you see?
When will he come back?
What must I do for you?
