环保问题日益严重，人们不断污染水和空气，请围绕这一话题展开讨论并给出建议，写一篇80词左右的文章，内容应包括以下要点。

The environmental problem is becoming more and more serious. People are polluting water and the air. One third of the world’s people don’t have enough clean water. More and more people get sick because of the air and water pollution. Human beings can not live without air and water. We must stop people from polluting the air and water. Don’t throw rubbish. Stop factories from pouring waste water into the river and waste gas into the air. We should also plant more trees and flowers .I hope everyone will care about our environment.

首先将所给提示译成英文。环保问题environmental problem，日益严重more and more serious，人们不断污染水和空气，表示没有停止，应用进行时表示动作的持续，People are polluting water and the air. 干净的水clean water，三分之一One third，这一句可像上文一样表达，也可写为One third of people don’t have clean water in the world. 越来越多的人More and more people，患病get sick，空气污染，水污染air and water pollution，“由于”可用because 或because of, because后跟句子，because of后跟短语，所以这里应用because of。人类Human beings，没有水和空气without air and water，无法生存can not live，阻止某人做某事stop sb from doing sth. 不要乱扔垃圾。Don’t throw rubbish.倾倒pour in to,废水，废气waste water，waste gas，植树种花plant trees and flowers。关键的短语理出来之后，调整句子结构就可以了。最后一句要尽可能号召人们保护环境可写为If we try our best our enviroment will become more and more beautiful.
