Modals of probability

I ... watch a programme about animals tonight.

That ... be the longest snake I`ve ever seen!

Phil ... be ill because he isn`t at school today/

It ... be a parrot. It`s the wrong colour!

I know you`ve lost your book. ... this be it?

You ... be really excited - you have tickets for your favourite band!

Taylor ... call me later but she`s not sure.

I`m tired. It ... be time for bed.

It ... be Alli playing the piano. She plays better than that.

I think it ... rain today - look at the sky.

My little sister is in a bad mood but she ... be hungry.

This ... be for me - I don`t like this kind of magazine.
