I am a teacher, indeed a fresh teacher. Once i want to teach my students the Be verbs, I feel that I do have a problem. The problem is that how to make the idea of having the pronoun YOU athe plural be verb in both past and present times. Once I told them that it is to be treated as a plural pronoun permanently, but my leader told me that it is not a nice way to make it easier. So what is to do ,now?
