【考點】其他應用文寫作；環境保護．

【答案】Dear editors，
   I'm Li Ming.I am a student of Yangshan No.1 Middle School.Yangshan has changed a lot over the years.The streets in this city are very clean.The mountains have turned greener，the rivers have become cleaner and the sky has been bluer.There are trees，flowers and grass everywhere.
   However，there are also many problems of environmental protection in Yangshan.People catch a lot of fish every day and pour wastewater into the sea，causing ecological changes in the ocean.What's worse，people throw garbage everywhere and burn things to make energy.All of these have led to our environmental problems becoming increasingly serious.
   To solve these problems，we should try our best to plant more trees.Secondly，we can cycle and walk instead of going to school by bus.Only by changing the way we treat the environment can we get along well with it.
Yours，
Li Ming
