　　What Lessons Should Be Learned From the Drought
　　The drought in the south-west China has lasts for several months, which makes people face water and food scarcity. We should learn lessons from it.
　　The drought can be cause by several factors. Firstly, about 63 percent of cities in China are facing water scarcity. The situation is worsened by pollution and industrialization. In addition, too many trees have been cut down, so forest coverage has been decreasing rapidly. What's more, some water conservation projects haven't been functioning properly, thus people there have had to rely more heavily on rainfall for their water supply. Most of China's irrigation systems are very old.
　　In order to prevent this case coming about again, we should improve our awareness of saving water, making proper use of water and recycling water. Meanwhile, we ought to plant more trees and protect environment to prevent loss of water and soil erosion. Of course, the governments should increase investment and repair water conservation projects as timely as possible.
我们应该从干旱得到什么教训

在中国西南部，干旱已经持续了几个月，这使得人们面临的水和食物的短缺。我们应该从中吸取教训。

干旱可由多种因素引起的。首先，中国百分之63的城市面临水资源短缺。这种情况是由污染和工业化导致的。此外，太多的树木被砍伐，森林覆盖率急剧下降。更重要的是，一些水利工程没有合理建设，因此人们不得不更加依赖降雨来保持他们的水供应量。中国大多数的灌溉系统是很老旧的。

为了防止这种情况再次发生，我们应该提高节水意识，合理利用水和循环水。同时，我们应该种更多的树和保护环境，防止水土流失。当然，政府应尽可能及时加大投资和维修水利项目。
