big floods 大洪水

　　Last summer, big floods occurred in both the south and north of China. They were the most serious ones in this century. They caused great loses.Fields were ruined, houses were washed away and many people became homeless.
　　There are three reasons for the floods. First, it had kept raining for months. Secondly, many forests had been cut down and the soil was washed away. Finally, some lakes had been turned into fields, which seriously blocked the waterways.
　　Now, some measures have been taken to prevent floods from happening again. The trees along the rivers have been protected; old dams have been rebuilt and some fields have been turned back into lakes again.

去年夏天，大洪水发生在中国的南部和北部。它们都是这个世纪以来最严重的。它们造成了很大的损失。土地被毁坏，房屋被冲走，许多人无家可归。 爆发大洪水有三个原因，首先，几个月以来一直下雨。第二，许多森林被砍伐，土壤都被冲走了。最后，一些湖泊已经变成了土地，这严重阻碍了水的流通。 现在，已经采取措施防止洪涝灾害再次发生。沿着河流的树木得到了保护；老坝已经重建，有些土地已经变回湖了。
