Bonsoir, j'aurais énormément besoin de votre aide pour corriger ce dialogue ci-dessous.

Hum, Okay. I'm your teacher in English and my name is... what is my name ? Oh, whatever, my name is not important. So, in my class you are here to work quietly and they are many rules ; yes, you did hear right "they are many rules".

Let's see, about your obligations :
You have to speak English in class.
You must participate in class.
You have to raise your hand before you speak.
You have to do your homework.
You must be on time.
You must respect each other.

Hum, concerning your interdictions,
You mustn't chat in class.
Don't forget your material.
You are not allowed to use your cellphone.
It's forbidden to speak French.

And finally, about your possibilities :
You can help your classmates.
You can watch English movies/series at home to improve your English.
You can ask questions to your teacher, me, when you don't understand.
Well, I think that's all, goodbye.
