Well done, Fatma. 

I can see that you are struggling, perhaps because you don't understand your teacher, and my advice to you is:

1- ask your teacher to speak slowly and more clearly

2- practice writing on italki and ask for corrections so that you can see your mistakes.

My English Teacher

I am taking an English course, and I'm so happy to be learning new language but l can't communicate with my teacher. He is American and he speaks so too fast.
When he asks me a question [or "When he speaks to me"], I asked him to repeat what he said again and again.
Don't you think that we should learn with someone that we can communicate with each other??

Whenever he asks me something, I asked him to repeat what he said again and again. (Again doesn´t have a space)

I think if you try hard enough, you can succeed! The harder the challenge, the more satisfying the victory :) You're doing so well already!
