I’d like to go to a beautiful place. I think it would be Beijing. Beijing is not only our capital city, but also a famous city with long history and wonderful culture. Beijing is also China’s political and cultural center. There’re many old places of great interest, such as the Great Wall, the Summer Palace, the Forbidden City, the Temple of Heaven, and Square. Once you see Square, you will think of Beijing. It has been the symbol of Beijing since 1949.
我想去一个美丽的地方。我觉得那应该是北京。北京不仅仅是我们的首都,也是有着悠久的历史和精彩地文化的著名城市。北京也是中国的政治和文化中心。有很多古迹,比如,长城,颐和园,紫禁城,天坛,天安门广场。只要你看到天安门广场,你就会想起北京。自从1949年起它就是北京的象征了。

On summer holiday my parents took me to Beijing. We stayed at Huabei Hotel. On the first day, we went to the Great Wall. The Great Wall is very long and old. It has millions of bricks. Each brick is very big and heavy. Lots of people from different countries like climbing the Great Wall. We felt very tired when we climbed to the top of the Great Wall.
We also went to the Palace Museum. The Palace Museum has 9999 palaces. It has a very long history. I bought a lot of souvenirs of the Palace Museum. What nice palaces these are! I visited the Palace Museum and felt excited. If you want to know more about the Palace Museum, you can go to Beijing and have a look. The following days, we went to the Summer Palace, Tian Tan, North Lake and Xiang Hill. I now know more about the history of China. I also like modern Beijing. The 2008 Olympic Games will be held in Beijing.
Later, I went back with my parents by train. I really enjoyed the trip to Beijing. I like this trip!
