要特别注意人称的转换!
一般疑问句是疑问句的一种.它是指用yes（是）或no（否）来回答的句子.
其结构是：
系动词be/助动词/情态动词+主语+其他成分
　　通常回答为：
　　肯定：Yes,+主语+提问的助动词.
　　否定：No,+主语+提问的助动词+not.
　　如:
Are you from Japan﹖
　　Yes I am． / No I'm not．
Is her sister doing her homework now﹖
　　Yes she is． / No she isn't．
Does he work in a bank﹖
　　Yes he does． / No he doesn't．
Do you live near your school﹖
　　Yes I do． / No I don't．
Can you speak French﹖
　　Yes I can． / No I can't．
May I go home now﹖
　　Yes you may． / No you mustn't．
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﹖
