今天,阳光明媚,是我们期待已久的日子,老师带我们去远足。走在路上,我们一边唱歌,一边欣赏路两边的风景,我们看见了嫩緑的小草从地里悄悄地探出小脑袋,路边的柳树緑了,微风吹来,柳树微微摆动枝条,像仙女一样翩翩起舞。金黄的油菜花开了,远远望去,像一片黄色的海洋,还发出阵阵清香呢!小鸟叽叽喳喳地唱着好听的歌,好像在欢迎我们的到来。看了这美景,我们一点也不觉得累了。
到了目的地——沙澧公园,老师把我们安排好地方,我们把吃的喝的都拿出来了,有方便面。薯片……,我们铺好桌布,大口大口地吃着我们带来的美味佳肴,吃完后,我们和老师照了相,并且和我们一起做一些有趣的游戏。
时间过得真快,转眼快到中午了,老师让我们站好队,准备回学校了,我们依依不舍地离开了沙澧公园。
as we know , water is very important to man, we can’t live without water. the amount of water which is suitable to drink is less and less. but some people don’t care about it .they waste a lot of water in their daily life. even worse, they pour dirty water in to rivers. they throw rubbish into rivers , too. many rivers and lakes are seriously polluted.something must be done to stop the pollution. only in this way can we live happily. if we don’t save water, the last drop of water will be a tear-drop of us.
we know that despite the fact that seventy percent of the earth's surface is covered with water, only a little part of it is fresh water. yet the demand for fresh water in our daily life and in industry seems great. moreover, with the expansion of the population and development of industry, the amount of the fresh water needed will increase even rapidly. it is estimated that if such a trend continues, the fresh water on earth will be exhausted very soon. what is worse, more and more water resources are being polluted, making the water unfit to use.
in addition,we must warn the people of the importance of water and the danger we are facing.for example, in most asian societies where rice is the staple food, the water used after cleaning rice contains various nutrients for plant growth and is an excellent detergent to flush the toilet. furthermore, the intriguing idea of converting the inexhaustible sea water to fresh water supplies will be the ultimate solution.
