文章結構
話題寫作講解
Dear mayor,
I want to talk to you about the river close to our school.
The river is very dirty now. Many people throw rubbish into the river. Also, some factories pour wastewater into it. As a result, it becomes very dirty. I know there were lots of fish in the river before. The dirty water killed most of the fish and there are few in it now. If there is no clean river, the fish will all die one day.
I think it is very important for us to protect our environment. We can't live without fresh air and water. Let's stop polluting the river. I hope that everyone will take some measures to protect our home.
Best wishes.
Yours,
Jack
