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

如题所述

  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?
