помогите по английскому. Нужно письмо Вену. Спасите, помогите

Hello Ben ! How are you ? What do you think is the most important school subject?

I think that English is the most important subject in school. Because I want to become a teacher of the English language, and for this profession I need to know English. Also, this foreign language can be used in any country, since in every country children learn this language. What is the most important subject for you? Who do you want to become ? I hope you read this letter and write me an answer.                             Your girlfriend ....... .
