英语变一般疑问句有什么技巧.

1．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 1﹖ 　　
We're watching TV． → 　　Are you watching TV﹖ 　　
2．陈述句中有情态动词（can may must …）时,也可直接将它们提至主语前,即可成为一般疑问句.
如：He can swim now． → 　　Can he swim now﹖ 　　
The children may come with us． → May the children come with us﹖ 　　
3．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﹖
