Dear Mr. Wang,
I am very happy to hear from you.I am getting on well with my English now. As you know, my English is not so good before, but I changed my way of study and have made some progress.
I tried to read the text before class, listening to the teacher carefully and do my homework in time. Asking questions is a very effective way to study.
But I still have some problems to solve. Grammar, for example, is one of them. Sometimes I am just confused with some kinds of clauses. therefore I hope you can explain some grammar rules more clearly and give me some specific suggestions on clauses.
Becoming a tourist guider is my ideal job in the future, so I will try my best to do more practise whenever I have got the chance to improve my spoken and written English.
All the best!
yours .
