Thank you for your help, it helps me to grow!
Well, actually I don't have problems to understand the verb to be.
The great problem is that here, in my country, some of the teachers in the highschool teaching the verb to be like bore thing. So I want to teach it using a better way, with reason for my students.
Do you believe that study English can be something much pleasant?
I think so!
If you can give me some tip of how I can do it, thanks, ok!!!
