1.今天，我们谈论了严重的污染问题。
2.第一个问题是河流非常脏。主要原因是人们往河里扔垃圾，工厂也往河里排放废物。
3.另一个严重的问题是空气污染很严重。我认为一个原因是如今路上的汽车越来越多了。而且燃烧煤炭的工厂也会排放大量黑烟，污染空气。
4.最大的问题是垃圾和废弃物太多了。这是因为人们每天都在扔掉像木筷、塑料碗和塑料袋之类的东西。而且他们还在公共场所乱扔垃圾。
5.那么，我们能做些什么来保护环境呢？首先，对于水污染问题，我们应该给政府写信，要求他们关闭那些工厂。每个人都应该帮忙清理河流。
6.其次，为了减少空气污染，我们应该乘坐公共汽车或地铁，而不是开车，我们也可以骑自行车。
7.第三，对于垃圾污染问题，我认为像自带购物袋去购物这样的小事就会有所帮助。并且最好把垃圾扔进垃圾桶里，保持公共场所干净整洁、美观。

Today we talked about serious pollution problems.
The first problem is that the river is very dirty.The main reason is that people are throwing litter into the river and factories are putting waste into the river.
Another serious problem is that the air is badly polluted. I think one reason is that there are more cars on the road these days. And factories that burn coal also pollute the air with a lot of black smoke.
The biggest problem is that there is too much rubbish and waste. That’s because people are throwing away things like wooden chopsticks, plastic bowls and plastic bags every day . And they are also littering in public places.
So what can we do to protect our environment First, as for water pollution,We should write to the government and ask them to close down the factories. Everyone should help to clean up the river.
Second,to cut down air pollution, we should take the bus or subway instead of driving, we can also ride a bike.
Third, for the waste pollution, I think simple things like bringing a bag to go shopping can help. And it is best to throw rubbish in the bins and keep public places clean and beautiful.
