Dear Dennis,
I'm very happy when Iget your letter.
Don't be dismayed.Here are some advices.
First you said your new school is very beautiful.I think a nice environment is good for you to make friend.You can make a self-introduction so that other people can know you well.You also actively and say "hello to others.
Then don't worry about your grades.Your teachers are kind for you.You can ask the teacher for help when you had problems.Don't be shy.That's nothing.Why don't you ask your classmate for help?It can not only improve your grades but also let you get on well with your classmate.
In the end,I hope you can make many friends.And scores more and more good

Keep healthy and happy,you'll have a good time.
Please write to me soon.
