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。
