答案：
Dear Lily,
In the letter, you asked me something about CCTV International. Now I will give you some information about it. CCTV International, which was launched on September 25, 2000, is the English-language channel of China Central Television. I like the channel and there are three reasons.
To begin with, it focuses on reporting about Chinese politics, economy, culture, tourism, customs, and society to its audience at home and abroad. Meanwhile, it covers the international events. I can keep up with what has happened and what is going on around the world through it. Last but not least, we can practice our listening while learning what is happening in and out of China.
In my opinion, CCTV International is a very useful channel. I spent most of my time watching its programs and I wish you will be interested in it, too.
Yours,
LiHua.
