Hey, Mark, maybe we could go swimming in the river later this afternoon.
嗨，马克，或许今天下午晚些时候我们可以去河里游泳。
I don't think I want to go, Tony.
托尼，我觉得我不想去。
Why not?
为什么不想去？
I was there last weekend and the river was really dirty. Even the bottom of the river was full of rubbish, and there were no more fish for fishermen to catch.
我上周末去过了，那条河非常的脏。甚至河底都满是垃圾，渔民也再也抓不到鱼了。
No way! It used to be so clean. In fact, it has always been the nicest river in this town.
不可能！这条河过去很干净。事实上，它一直是镇上最美的河。
Not anymore. I think people are throwing litter into the river. Factories are also putting waste into the river.
不再是了。我认为是人们在往里边扔垃圾。工厂也往河里排污。
That's terrible! We should write to the government. They should close down the factories.
太糟糕了！我们应该给政府写信。他们应该关闭这些工厂。
Good idea! But I think everyone in this town should help to clean up the river, too. Everyone should play a part, not just the government.
好主意！但是我认为镇上的每个人也都应该帮助清理河流。每个人都应该参与，而不是仅靠政府。
