Saving Water
The world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earth's surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.
However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?
We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.

在我理想中的大学要有良好的学风,要有几个知已好友,可是一起笑一起哭一起讨论学术问题,要有渊博的教授上一些好的课程,要对未来有一种憧憬并且可以付出实际行动,要知道未来的方向.
理想中的大学可以让我成长,可以让我在毕业的那一年感到骄傲,并且知道要往哪里继续走下去,让我四年后在回顾的时候可以骄傲的说,我学到了很多,我舍不得离开,要和大学里的好朋友做一辈子的好朋友.
另外,这样也行
从如下三方面为你提供参考!
学习:想做到最好,可是发现太难了,读书这么多年,突然没有人来监督了,自己都松懈了,所以,只好崇拜——及格万岁!!!
生活:又一次过集体宿舍,哥六个!但是离家超远了,刚来的时候很想家,但是慢慢的熟悉学校和周边的人后,发现大学生活真的是自由啊!谈恋爱,泡网吧,喝酒,聊女生,打扑克...每个人的追求都是不同的,我只希望自己的大学生活过的惬意,自由,仅此而已!
工作:不幸中进入学生会,参加社团活动,最喜欢的就是帮贫扶贫,突然发现自己仍然还是热血青年啊,印象最深的就是去盲人大伯家包饺子,为什么中国穷苦大众这么多呢?!government都干什么了?!认清这个社会就是弱肉强食,你不强,那就老实儿给别人打工吧!
