Hi Teachers,
Please help correct my letter if there are any mistakes, thank you.

Dear Mark,

How have you been recently?

I am writing to thank you for your family’s kindness and hospitality during my stay in your home.

I really learned a lot about western traditional customs and culture from you and your nice parents.

There is a final exam in the coming month, so I have to spend most of my time preparing for it.

I practice English writing and listening and do masses of science homework every day. Besides, I have to go to dance studio to practice Ballet after class. My mom registered a ballet competition for me. To be honest, I am a little nervous because the competition is held on next Friday night. I don’t have enough time to practice.

However, I found a good way to master my emotions. Every time I feel tired, I will go downstairs and run in the nearby stadium; running is really helpful to energize my body and relax my mind.

I will recommend you to run when you lost your flight and faith, it really works.

How are you getting along with your studies? You said there was a funny French teacher in your last letter; will you tell me something funny about her and teach me some French words?

I am looking forward to hearing from you and please give my best regard to your parents.

Sara
