1.今天，我們談論了嚴重的污染問題。
2.第一個問題是河流非常臟。主要原因是人們往河里扔垃圾，工廠也往河里排放廢物。
3.另一個嚴重的問題是空氣污染很嚴重。我認為一個原因是如今路上的汽車越來越多了。而且燃燒煤炭的工廠也會排放大量黑煙，污染空氣。
4.最大的問題是垃圾和廢棄物太多了。這是因為人們每天都在扔掉像木筷、塑料碗和塑料袋之類的東西。而且他們還在公共場所亂扔垃圾。
5.那么，我們能做些什么來保護環境呢？首先，對于水污染問題，我們應該給政府寫信，要求他們關閉那些工廠。每個人都應該幫忙清理河流。
6.其次，為了減少空氣污染，我們應該乘坐公共汽車或地鐵，而不是開車，我們也可以騎自行車。
7.第三，對于垃圾污染問題，我認為像自帶購物袋去購物這樣的小事就會有所幫助。并且最好把垃圾扔進垃圾桶里，保持公共場所干凈整潔、美觀。

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.
