The Polluted Moat-污染的护城河
我们城市周围的护城河最近被严重污染了。以前曾经在水里自由自在地游来游去的鱼儿都不见了，脏水直接从造纸厂倒人护城河。日复一日，漂亮的护城河已经变成一个恶臭的垃圾箱。
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.
