Sample 4：A letter on  lending money  英文书信(借钱)
　　Hi ！ Alice ,
　　I'm glad to hear from you. Yes, just like you, sometimes I have the same problem. I think if she really needs the money. You had better lend it to her. You don't need to worry too much about it. Maybe she will pay you back when she has money. You just think, If you don't lend her the money ，I'm afraid(that)you may lose this friend．
　　I believe everyone may have trouble in life and we should help each other. So when my friends need money, we should try to help them. Maybe we will get it back, or maybe we won't. Sometimes making friends means you may get more on one hand and less on the other hand.
　　I hope it can help you．
　　Yours，
　　Liu Ming

　　Sample 5：A letter on talking bus service in Beijing     英文书信(北京公共交通)
　　Dear Tony,
　　I am glad to know your grandpa is coming to Beijing.
　　Yes, your grandpa is right. The bus service in Beijing is really good now. there are more than 900 bus lines all over Beijing and bus can  even take you to some small villages. Besides, special(yellow) seats are provided on buses. People do not have to spend a long time waiting for a bus and the tickets are very cheap.
　　I like taking a bus because I think it is comfortable and also good for our environment. So it is a good choice for your grandpa to travel by bus in Beijing.
　　If you have more questions, please ask me.
　　Yours
　　Liu Jing
