陈述句变成一般疑问句:
陈述句变为一般疑问句，首先看句中有没有系动词be或情态动词，如果有，把be或情态动词直接提到句首就可以了；如果没有，要用助动词do 或does 来帮助。基本句式如下：
若划线部分为Tom，Tom 是个人，且作主语，则疑问词应选Who， 此句应该为 Who bought a new computer from the store yesterday?
若划线部分为a new computer， 划线部分为物，则疑问词为what，此句应为 What did Tom buy from the store yesterday?
若划线部分为from the store,则疑问词应为Where，表示地点，此句应为 Where did Tom buy a new computer yesterday?
若划线部分为yesterday,则疑问词为When，表示时间，此句应为 When did Tom buy a new computer from the store?
