读写任务(满分25分) 

阅读下面的短文,然后按照要求写一篇150词左右的英语短文。

An earthquake happened in Bam(伊朗的巴姆市) on December 26, 2003. About 30,000 people were killed and more were injured. Many of those killed by the earthquake died only because of poor building methods and a lack of proper regulation.

In Iran, as in many developing countries, earthquake that ought to be survivable(不致命的)often bring human disaster because buildings collapse (倒塌) on top of people. Two days before Christmas, California was struck by an earthquake similar in magnitude (强度) to the one that hit Iran Saturday, but only three people died, thanks largely to safer construction methods. A quake measuring 8.0 caused just 500 injuries and no deaths in Japan in September 2003.

Bam, however, was a disaster waiting to happen. Efforts to bring industrial development to what was a backward agricultural area caused a population boom (激增)and a shortage of housing, which local builders tried to meet with cheap homes, or by adding extra floors to existing houses. Many buildings collapse [even] without earthquakes, because of the poor construction.
