Dear Mr. Smith,

I want to speak to you about the state of the playground.     1    People are throwing their garbage everywhere. They leave garbage on the ground instead of using the garbage cans.       2    这对孩子们来说是一件危险的事情. Yesterday, a six-year-old kid fell and cut his hand on a broken bottle. Immediately,     3    the boy was taken to hospital. Also, the garbage makes the playground dirty and     4    没有人想去那儿

I would like you to handle this problem right away. For example,     5    you should buy more garbage cans and stop people from littering.

Please take my suggestions into serious consideration. I am waiting for your answer.

Best regards!

Jerry Broker
