The Polluted Moat-汙染的護城河
我們城市周圍的護城河最近被嚴重汙染了。以前曾經在水裡自由自在地游來游去的魚兒都不見了，髒水直接從造紙廠倒人護城河。日復一日，漂亮的護城河已經變成一個惡臭的垃圾箱。
The Polluted Moat
The moat around our city has been seriously polluted recently. There used to be many fishes swimming freely in it. But now none y water from the paper factory pours into the moat day after day, the once beautiful moat has turned into a smelly dustbin.
