Unit 13同步训练写作训练第2题详细解答过程和答案
Water pollution，air pollution，noise pollution and light pollution are four of the main kinds of pollution in the modem world.Water pollution not only kills plants and animals but can also cause people have cancer.We must stop littering in the rivers，and we should tell farmers to use chemicals less in the fields.Air pollution makes plants die and pollutes our food and water.To fight global warming，we should walk or ride bikes instead of driving，and the government should require factories to stop polluting the air.Planting more trees can help make air clean.Noise pollution can damage hearing and make people lose sleep.Reducing noise at home and reducing city noise are good ways to cut down on noise pollution.Light pollution is bad for eyes and makes people uncomfor[table]，so the lighting systems in the cities should be adjusted，and people could put up heavy curtains at home to reduce their discomfort from too much light at night.
