将陈述句变为一般疑问句时,如句中有be 动词（am is are …）时,可直接将它们提至主语前.如主语为第一人称,应将其改为第二人称.如：
I'm in Class 2Grade 1． →
Are you in Class 2Grade
We're watching TV． →
Are you watching TV?
陈述句中只有一个实义动词作谓语且其时态为一般现在时,变为一般疑问句时要在句首加do或does 主语后的实义动词用原形.如：
I like these animals． →
Do you like these animals?
She wants to go to the movies． →
Does she want to go to the movies?
