Tony: Hey, Mark, maybe we could go swimming in the river later this afternoon.
托尼:嗨,馬克,或許今天下午晚些時候我們可以去河里游泳。
Mark: I don't think I want to go, Tony.
馬克:我認為我不想去,托尼。
Tony: Why not?
托尼:為什么不想去?
Mark: 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.
馬克:上周末我去那兒了,河里真的很臟。甚至河底充滿了垃圾,不再有魚讓漁民去捕。
Tony: No way! It used to be so clean. In fact, it has always been the nicest river in this town.
托尼:不可能!過去它是那么干凈。事實上,它一直是這個鎮上最美麗的河流。
Mark: Not anymore. I think people are throwing litter into the river. Factories are also putting waste into the river.
馬克:不再是了。我認為人們正在把垃圾扔進河里。工廠也正在把廢物倒進河里。
Tony: That's terrible! We should write to the government. They should close down the factories.
托尼:那太可怕了!我們應該給政府寫信。他們應該關閉那些工廠。
Mark: 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.
馬克:好主意!但我認為鎮上的每個人也都應該幫助清理河流!人人都應該參與,不僅僅是政府。
