Do you go to school on foot? Does his father go to work by bus? 要将陈述句变成一般疑问句，可以遵循下列步骤： 1. 看句中有没有be动词（am、is、 are）、或情态动词（can、would、must等）， 如果有，将其提到句首，句末打上问号即可。 2.如果句中没有be动词、或情态动词，则根据谓语动词的形式借助助动词（do、does）放在句首。 具体方法是：如果谓语动词是原形，（即：主语是I, you, we, they, 及所有复数人称）则借do；如果谓语动词是第三人称单数形式，（即：主语是 she, he ,it 及所有单数人称）则借does； 需要注意的是，借does后，原句的谓语动词要变回原形。 注意：如果陈述句中有第一人称的，则变问句时要变为第二人称。 (即：I, we --you ; my, our– your) 归纳小结：如何将陈述句变成一般疑问句？ 二、特殊疑问句 I clean the window at home on Saturdays. 1、对主语提问： Who clean the window at home on Saturdays? 2、对谓宾提问： What do you do at home on Saturdays
