　　都江堰中兴镇发生山体滑坡(landslide)——这是2008年四川地 震时受灾最严重的地方。山体滑坡覆盖了大约两平方公里，摧毁了 至少11所房子。到目前为止，已有200多名居民被疏散。山体滑 坡几个小时后，巡逻队员到达现场时，一切都已经是一片汪洋。目 击者描述石头和残骸(debris)从山上滚下来，不到三分钟就把八座 房屋吞没了。

　　参考翻译：

　　The landslide occurred in the town of Zhongxing is Dujiangyan —one of the places badly hit by the 2008 Sichuan earthquake. The landslide, which covered about 2 sq km, damaged at least 11 homes. So far more than 200 residents have been evacuated. By the time patrol members arrived at the scene, a few hours after the landslide，everything was already a vast expanse of water. Eyewitnesses described stones and debris running down the hill and covering around eight homes in less than three minutes.
