is和does在疑问句中的用法是>?

过来看看，

is ,does 开头的都是疑问句，如果不知道怎么写，

先还原句子为陈述句。

比如：
Do you like the book?
I like the book .

用do 或者does 句子中一定要有 一个实义动词,比如“like”等等。

Is he a teacher?
he is a teacher

你的作业：Tony's father is reading a magazine.
___Is___Tony's father __reading__a magazine?
They come from New York.
____Do___they _____come__from New York?

问的详细点好不，不太明白
