一般疑问句怎么变?
系动词be/助动词/情态动词+主语+其他成分?  如:  Is this your pen?  Yes it is./No it isn't.  注意:  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﹖  4.一般疑问句一般读升调(↑)  5.一般疑问句有时不用yes或 no 回答.
