Dear Mr. Du,
I'm sorry to tell you that I can't go to school today. I've caught a cold because I went swimming yesterday.
This morning I had a headache and had a fever. The doctor advised me to stay in bed for two days.
Now I'm writing to you to ask for two days' sick leave.
乾隆年间：the reign of Qianlong
Now let me say something about Beijing Opera. Beijing Opera is very popular in China. It has a history of more than 200 years. During the reign of the Qianlong emperor in the Qing dynasty, Qianlong had a interest in the local opera. In 1790, to celebrate his eightieth birthday, he summoned opera troupes from different places to perform for him in Beijing. Four famous troupes from Anhui province remained in Beijing after the celebration. In 1828, A Hubei troupe came to Beijing and often performed together with the Anhui troupes. The two types of singing mixed together and gradually a new type came into being known as Beijing Opera. Now is the performance. I hope you will like it.
Well, the first place I suggest that you visit is the Great Wall, the longest wall in the world, which is said to be one of the wonders in the world. It has a history of more than twenty centuries. It is amazing to see such a huge wall was made entirely by hand.
The other place worth visiting is the Palace Museum, which was built in 1406. Twenty-four emperors once lived there. from there the ruling emperors issued orders. You can learn a lot about Chinese history by visiting this Palace.
What a pity that you can't stay longer, otherwise, you could visit many other historic places and beautiful scenes such as Summer Palace, Bei Hai park.. and so on.文章来自爱文笔_www.aiwenbi.com
