标题：The Pros and Cons of Entrance Fees for Parks

引言：

Many of my schoolmates have strong opinions on the issue of entrance fees for parks. Some believe that it is unreasonable to charge an entrance fee, while others think it is acceptable if the fee is not too high.

正文：

Arguments for Entrance Fees：

An entrance fee can be used to maintain and improve the park facilities, such as paying gardeners and purchasing plants and trees.

It helps to limit the number of visitors, ensuring a better experience for everyone.

Arguments Against Entrance Fees：

Parks are meant to be public spaces where people can enjoy themselves without having to pay.

An entrance fee may deter some visitors, especially those from lower income brackets.

结论：

While I can understand the need to maintain and improve park facilities, I believe that an entrance fee should be charged only if it is affordable and not a barrier to access for everyone.

建议：

The city could consider offering discounts or free entry days to ensure that parks remain accessible to all members of the community.
