用最高级描写一个地方的英语作文70个单词

There are a lot of water playgrounds in my city.
To be honest, i rarely go to visit these places before.
The main reason is that i do really have a great concern about the cleanliness of playground.
We are not sure about if the water is recycled or it is being replaced everyday.
Day in day out, many people visit there and they may not take proper way to clean their body before moving into the pool. Some people may even pee in the pool. I don't think there is a good indicator of the cleanliness of the water. For this concern, I never go there.
