Every city has many theme parks, the local people like to go to the park for a walk or take some exercise. In China, most parks are free, people can go there without charge, but still some other parks need to charge. People urge that all the parks should be free, while I think it will do harm to the park.

每个城市都有很多主题公园，本地人喜欢去公园散步或者锻炼。在中国，大部分公园免费，人们无需给钱就可以进入公园，但是仍然有一些公园需要付费。人们要求所有的公园应该免费，然而我觉得这样会对公园有害。

One the one hand, opening the parks for free encourages people to go to the park for entertainment. Most people have the habit to take a walk after dinner, so it can help them to keep their bodies healthy. The children can have fun with their friends, too. The parks provide people so much fun, so it is good for people to go to there for free.

一方面，免费开放公园鼓励着人们去公园娱乐。很多人有饭后散步的习惯，这样有助于让他们保持身体的健康。孩子们也可以和他们的朋友找乐子。公园给人们提供了很多的乐趣，因此免费开放公园对人们是有好处的。

On the other hand, too many people go to the parks will do harm to the environment. Some people will throw away their trash away, the environment will be polluted. What’s more, the crowed people will make people have less space for them to have fun.

另一方面，过多的人去公园会对环境造成伤害。一些人会随处扔垃圾环境会被污染。而且，成群的人会让人们享有很少的空间来娱乐。

For me, I think it is not good to open the parks for free, it needs to control the number of people, so we can protect the environment.

对于我来说，我觉得免费开放公园是不好的，要控制人群的数量，这样我们才能保护环境。
