Merhaba,

i want to know how ican i mprove my writing skills and how ican write an right sentence

Have you tried www.livemocha.com ? There is a practice section where you can write or record your answer for someone to correct you.
hope this helps

 You can do that from here. Read and try to write without look. It will improve your skill.

Why not do what a lot of other TC´ers do:

start a new thread. Say you are practicing (that way we feel free to correct you, knowing you want help, and that it won´t hurt your feelings). Write your sentence(s). Then we can all put corrections and comments, and try to explain why we changed it.

I found the best way to learn was this. My secretary would change what I wrote when she typed it, and I learned from my mistakes.

Best of luck

 thanks for you help
