As the world is getting more densely populated, pollution presents a severe problem. More people make more waste. All this waste is polluting our surroundings. It is high time we did something about pollution. I suggest more trees be planted to keep the air fresh. We should purify the water and make use of the wastes and turn harm into good. By cur common efforts, we will make a clean and purified environment for life and work.

A: How could that be? I thought bacteria just caused illness.B: That's not true. Bacteriologists have identified certain strains（种族，种类） of bacteria that “eat” petroleum products, such as oil and gasoline.A: That sounds strange. How does it work? B: They ingest（摄取，吸收） the petroleum and excrete（排出，排泄） hydrogen and oxygen, leaving a clean environment behind them.希望能有所帮助。
