假如你是李华,你的笔友mary说要来中国学习汉语,请你给她写封信,简单陈述你的建议；

Dear Mary,
I’m very glad that you’ll come to China .I know it isn’t easy to learn a foreign language, but I have some ideas that may help. Firstly, it’s very important to listen to the teacher carefully in class and make some notes so that you can go over your lessons later. Secondly, try to catch every chance to practice speaking, both in and out of class. Don’t be afraid of making mistakes. Then try to listen and read more in Chinese. What’s more, you’d better plan your time well and study it regularly every day.
encounter difficulties to the teacher and classmates for help
Above all, you should be confident in yourself and don’t give up whenever you meet with difficulty. I’m sure you will succeed through your hard work. Best wishes and looking forward to meeting you in China.
Yours,
liHua
