4、some 改成any。

如有I、you将其该成you、I。

二、肯定句改一般疑问句的方法——三步法

(注Does/Did后面的动词变回原形）
三、肯定句改特殊疑问句的方法——四步法
1、在一般疑问句的基础上，句首添加一个疑问词即可，可根据划线部分确定是什么疑问词。

2、接着找be动词或can，shall，will等放在疑问词后面，若没有则请助动词do/does/did帮忙，写在疑问词后面，how many除外，必须先写物品，再写be动词等。

3、划线部分去掉后剩下的内容照抄，（some 改成any，my改成your等）
4、句点改成问号。

如：what （什么）\how(怎样)\ who（谁）\ which（哪一个）\why（为什么）where（哪里）how many（多少）\how much （多少钱）\what colour（什么颜色）\ how old（多大）\……等等……
