Dear Lin,
I am glad to talk to you.I know that you are learning Enlgish now and confronting some problems. Yes? Learing English is not so easy for any person whose mother tongue is not English. But I want to say that if you can be persist in learing it, you can make it at last. Finaly, learnig English is not just remembering word, as you think. It's a complicated and difficult course.
