Economize Water Resource
The world is not only hungry but also thirsty. However, some people are still reluctant to turn a finger to save water. Some people don't turn a tap after use, while others even pollute clean water and make the situation worse. The severe drought in the southwest China once again pushes the issue of water-saving under hot discussion.
这个世界不仅很饿，而且很渴。可是，有些人仍然不愿意费一点儿功夫去节约用水。一些人用完水后不关水龙头，而另外一些人甚至污染干净的水，这使情况变得更糟糕。中国西南地区的严重干旱再一次将节水问题推向了讨论的热点。
However, as things stand today, the reasonable utilization of water resource is more significant than before. Firstly water consumption is soaring. The quick development of commerce and industry will consume more water for their reproduction. What's more, the great increasing of the world population also further aggravates the situation. Secondly, due to the more and more serious water pollution, the supply of clean water fails to meet the demand.
然而，当前的情况是，合理利用水资源比从前更加重要。首先，水资源的消耗在飘升。商业和工业的快速发展消耗的水比再生水资源要多。另外，世界人口的大幅增长也使情况进一步恶化。其次，由于水污染越来越严重，洁净水的供应满足不了需求。
As a college student, not only will I save water by myself, but also I will attend different kinds of activities on water-saving. On the one hand, I will make the best of water instead of throwing clean water away at instant. On the other hand, I will call on my friends to save water and protect water.Anyway, many a little makes a cackle.

作为一名大学生，不仅我自己要节约用水，而且我会参加各种节水活动。一方面，我会充分利用水资源，不会在瞬间就把干净的水倒掉。另一方面，我会号召我的朋友节约用水，保护水资源。无论如何，聚少成多，滴水成流。

点评：前一句运用了拟人的修辞手法，把The world赋予了生物体的特征。后半句运用了一个非常形象的短语turn a finger to，表示举手之劳。
