Hi Miss (her surname)

How are you? I'm now in Qatar, and work in a big company here.
I'd like to thank you for everything you did for us. Everytime I speak English here, I remember you and your help in English.
I'm improving my English a lot here because I have to use it every day and I'm also thinking of doing the TOEFL exam again, maybe in 2 months.

Please send my regards to all the secretaries, students and teachers in the Institute, especially Mr.Selim, because I don't have his e-mail.

Yours truly

I have corrected it only to a certain standard - a native speaker would express/write some parts differently. But we don't want to deceive your teacher!
