Ответ:

There are twenty-five children in my class.

Are there any biscuits left? No, I'm sorry, I ate them all.

It is winter now. Are there any leaves on the trees?

Can we listen to some music? No, there is a radio in this room.

Can I have some sugar in my coffee? No, I'm afraid, there isn't any left.

Надеюсь что помог!
