一般疑问句和特殊疑问句
1、 一般疑问句的定义：对于只用Yes 或No来回答的疑问句我们叫一般疑问句.
2、 特殊疑问句的定义：对句子当中某一部分内容的提问我们要用特殊疑问句，比如问时间用
When或者what time 问地点用where...
这里我们主要学习特殊疑问句的用法.
3、 特殊问句的用法：特殊问句是由 疑问词 + 一般疑问句组成 ，那么在我们使用特殊问句时， 要先选好疑问词，特殊疑问词有很多，需要长期积累。
例如：I want to go to sleep now. 如果对go to sleep 提问 ，那么我们应该问你想要做什 么，首先应选择疑问词what ,再将剩下的句子变为一般问句即可.
What do you want to do ?
