Dear Linda，

　　I'm very glad that you'll come to China to watch the Olympic Games. 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。

　　Above all，you should be confident in yourself and don't give up whenever you meet with difficulties. I'm sure you will succeed through your hard work。

　　Best wishes and look forward to meeting you in China.
