用be动词造一句话改为否定句、疑问句，做否定回答，做肯定回答

Question

如题所述

Answer 1

　　例句：Tom is in the classroom.

否定句：Tom isn't in the classroom.

含be动词的肯定句做否定句时，是在be动词的具体形式后加not。又如：

We are students.---- We aren't students.

一般疑问句：Is Tom in the classroom?

肯定回答：Yes，he is.

否定回答：No, he isn't.

含be动词的陈述句改一般疑问句时，是将be动词的具体形式提前到句首。又如：

They're very happy. ---- Are they very happy?

Answer 2

i am a boy
i am not a boy
are you a boy
yes,i am
no,i am not
