用英语描述一个北京著名景点

下面一篇是写北海公园的：
I usually go to the Beihai Park when I have time and opportunity. And there are a couple of reasons to name.
First because it is among the most beautiful parks in China. If you go there, you will see lines of trees with history of more than 500 hundred years. In the sunny days, you can see many pigeons walk on the lawn.
Secondly, it is a large park and therefore I can get a sense of freedom there. Each spring, I will go to that park to fly a kite with my friends. I like to lie on the green grass and see the kite fly in the blue sky, as you can imagine, it is such a wonderful thing to do!
Finally, there is a big lake at the center of this park. In summer, I often go boating on it and in winter I can even skate on it when the lake was frozen over.
These are the reasons why I appreciate this park so much.
