答案是:
One possible version: September 16,2012,Sunday I went to the small city far away from villages to buy some books this morning.What Isaw there surprised me very much.There is a river in the city.The water in it is dark and smells terrible.It is polluted with chemical waste fron factories.There are many small factories along the river.Their waste is poured directly into the river.The worst one is the paper factory.It pours waste water into the river day and night.Fish can't live in such a polluted river and neither can people swim in it.I wonder why people don't care about our environment.We should do something to reduce pollution.
