Translation of arenero

I try to learn English as much as possible so that I can travel next year to the United States. I would agree to your proposal but I also need to find good teachers. My goal is quality and speed.
Yes, but on the other hand, using full, simple sentences also helps people who are learning the language more than just the short clauses. It is probably a mix of both, but I have not decided yet which ratio is the best for us.
Do not worry, please, all is well here. I find it fascinating how fast you can write texts in foreign languages. I know how hard it is, and I congratulate you. Waiting to your next email.
