[篇一:水的重要性]

[篇二:英语作文水的重要性]

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.

People can’t imagine life without water. Without it, the earth we live on would be a dead one. There would be no trees, no crops, no animals and no people.Although nearly three quarters of the earth’s surface is covered with water, it is sea water and undrinkable. The demand for water is increasing, while water resources are scarce. So water shortage has become one of the most serious problems.Fortunately, people have realized this pressing problem and are trying to find ways to salve it. First, people are urged to economize on water. Second, measures are taken to protect water resources. Third, circulating water is used for industrial purposes over and over in factovies and treated sewage water is used for irrigation in farming land.

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.

关于和谐的作文:人、水——和谐

我还记得,我曾在电视上看过这样一则公益广告:

画面上首先是一个水龙头,它正哗哗地向外流淌着干净而又透明的水;后来水龙头里流出的水浑浊了,水流的速度也慢了许多;紧接着,流水改成了滴水,样子十分艰难;到最后,画面上出现了一只眼睛,流出一滴眼泪,下面是一行字:如果人类不珍惜水,最后一滴水将是自己的眼泪。

多么形象的画面啊!可是有人却在无止境地浪费着珍贵水资源。

上一次,我随爸爸到一家洗车行洗车,那里的工作人员用水枪洗车,爸爸见了,摇了摇头,无奈地说;唉,你们真浪费!我听不懂,忙问爸爸:爸爸,你说他们浪费什么呀!水呀,宝贵的水资源!

得到了爸爸的答案,我便不再追问了,因为我知道水的重要性。在地球这个大水球上,海洋虽说占了71%,可人类可以利用的水只占其中的0。26%。但我的心中还是有个疑团:为什么用水枪洗车会浪费水呢?不过,看着在地上静静流淌着的水,我也不禁叹了口气。

事后,我上网查资料,发现如果使用循环式洗车装置的话,洗一辆车只需10升到15升的水,而如果使用水枪喷洗的话,则需要约1吨的水,多么惊人的差距,这些浪费的水足够可以让我用上十天半个月。

唉,不说了,像这样的事例还多得是,幸好还有些人懂得珍惜水,奶奶的邻居王伯伯就是一个好例子。

王伯伯和老伴每个月用的水很少,水费只是奶奶家的2/3。因为,王伯伯总是一水多用:他用掏米水洗菜,洗菜水冲厕所;用洗衣服的水拖地板

那天,我到奶奶家玩,看见王伯伯家室外空调机下放着一个大水桶,空调水滴答滴答地往桶里掉,我很惊奇,心想:这是在干什么呀,空调水像雨水一样是未经净化处理的水,接了又有什么用呢?

我性子急,忙跑到王伯伯家里,正巧,王伯伯在院子里摆弄他养的花草,他见我来了,笑眯眯地说:何娴啊,来,帮我看看这几株蝴蝶兰哪株更好看。我指了指中间的那株,说:这株。然后又忍不住问道:伯伯,外面接空调水干什么用呢?浇这些花啊!王伯伯一边挪花盆一边说到。可是空调水和雨水一样不太干净啊!我疑问地说。雨水可以浇花的呀!王伯伯看着我说到,我听了,一拍脑袋,哎呀,我怎么就忘了这点!

王伯伯又接着说:上星期,我看了一篇文章,文章上说,‘空调水是未经净化处理的水,可以用来浇花,但是不能饮用’那时,我突发奇想,如果我把室外的空调水积攒起来,不就正好可以用来浇我养的那些花,这样不就又可以

节约下很多水吗?说着,他自豪地笑了,我也笑着夸奖说:伯伯,你真棒,节水的点子这么多!

他又是呵呵一笑,说:节约创造价值,你看现在用水这么紧张,为了让人口和水‘平均’一下,我们也应该做一点力所能及的事吧!

那多么朴素的话语啊,我不禁发出了感慨:要是人人都像王伯伯一样节约用水,这节约下的水该有多少呀!

那么,我们就能达成目标:人、水和谐
