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.
每個城市都有很多主題公園，本地人喜歡去公園散步或者鍛煉。在中國，大部分公園免費，人們無需給錢就可以進入公園，但是仍然有一些公園需要付費。人們要求所有的公園應(yīng)該免費，然而我覺得這樣會對公園有害。

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，免費開放公園鼓勵著人們?nèi)ス珗@娛樂。很多人有飯后散步的習(xí)慣，這樣有助于讓他們保持身體的健康。孩子們也可以和他們的朋友找樂子。公園給人們提供了很多的樂趣，因此免費開放公園對人們是有好處的。

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，過多的人去公園會對環(huán)境造成傷害。一些人會隨處扔垃圾環(huán)境會被污染。而且，成群的人會讓人們享有很少的空間來娛樂。

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.
對于我來說，我覺得免費開放公園是不好的，要控制人群的數(shù)量，這樣我們才能保護環(huán)境。
