1、一、变一般疑问句移：把be动词、情态动词、助动词移到主语之前，加问号即可。

2、如:He is a student----Is he a student?(含be动词)I can speak English----Can you speak English?(含情态动词)I have learnt English for 5 years.---Have you learnt English for 5 years?(含助动词)2、加：加助动词。

3、看原句的时态判断加哪个助动词。

4、如：I like it.---Do you like it?（一般现在时加Do ）He likes dogs.---Does he like dogs?（一般现在时单三加Does）She went to the park yesterday.---Did she go to the park yesterday?（一般过去时加Did，然后要把原来的过去式went变为原形go）二、特殊疑问句 一变：把原来的陈述句变成一般疑问句。

5、 二加：加特殊疑问词（what,where,how,等） 三去：去掉划线部分。

6、There is (a book) on the desk.----what is on the desk?疑问词怎么选要看就什么提问，就时间提问用when ,what time，就地点提问用where，就物提问用what，等等。
