一般就根据语意选择适当的疑问词,有where、when、what、why、who、how、how long、how ofen等,将疑问词放在最前面,然后是助动词,其它成分还按照原来顺序就好了；有的不需要疑问词,那就将助动词提前,其它的还按原来顺序.例如：She is the girl I have ever refered to you.改为疑问句Is she the girl you have ever refered to you?
The girl always goes shopping once a week.改为疑问句How ofen does the girl go shopping?
其实如果抓住它的规律,你就会发现挺容易的.希望能到帮你一点
