What a beautiful hat it is!
Don't open your eyes.
Whose are new?
Which girl is his sister?
Which class are you in?
比如：he does't like you.改为 he hates you 否定句里面一般都有否定词.包括 no not never seldom hardly 等.把它改成肯定句 你可以找动词的反义词.
Where is she?
What does your mother do?
My mother is not a teacher.
Does your father work in a hospital?
在be动词后加not如：
肯定句：He is a teacher.
否定句：He is not a teacher.
这是一否定句.这不是一个我们可以掉以轻心的问题.
