篇1:初一水的自述

全文共 711 字

+ 加入清单

大家好,我是大家熟悉的,以前的我,美丽清澈,而现在的我,又臭又脏。而这一切的一切,都是人类造成的。

以前的我,伴着泉水的叮咚响,唱着欢快的歌,一路欢快的跑着,许多的人都会在我的身边散步,嬉戏,我总是快乐的。而现在,一切都变了,工厂里排放出来的废水流进了我的身体,前来游玩的人们总会把垃圾扔在我的身体上,日积月累,我身体上的垃圾越拉越多,原来清澈的我也变得肮脏不堪,人们经过我的身旁总会捂紧鼻子,逃命似的从我的身旁跑过,每当这时,我总会流泪,我替人类感到悲哀。

我是生命的源泉。人类对我的需要仅次于氧气。人类如果不摄入某一种维生素或矿物质,也许还能继绩活几周或带病活上若干年,但人类如果没有我,却只能活几天。人体细胞的重要成分就是我,我占成人体体重的60——70%。人体的每一个器官都含有极其丰富的水,血液和肾脏中的水占83%,心脏为80%,肌肉为76%,脑为75%,肝脏68%,就是骨头也含有22%的水分。

人体的各种生理活动都需要我,比如我可以溶解各种营养物质,脂肪和蛋白质等要成为悬浮于水中的液体状态才能被吸收;我在血管、细胞之间川流不息,把氧气和营养物质运送到组织细胞,在把代谢废物运出体外,总之,人的各种代谢和生理活动都离不开我。

但是,人类好像对于这些都浑然不知似的,还是一味的破坏我,如果他们再这样破坏,那么世界上最后一滴水将是人类的眼泪。

人类只知道,动物和植物有衰老的过程,其实我也会衰老,而且,我的衰老对人体健康也有害,水分子是主链状结构,我如果不经常受到撞击,也就是说,如果我不经常处于运动状态,而是处于静止状态时,这种链状结构会不断地扩散,增大,最后就会变成人类所说的——死水。

”人类,快醒醒吧。“我呼吁道。

有人会说,——取之不尽,用之不竭,我们把水龙头一拧,自来水就哗哗地流出来了,为什么要珍惜呢?可你知道吗?我们国家的水资源虽然储量丰富,但可利用的淡水资源却很少。全国600多个城市中,有近400个城市缺水,110多座城市严重缺水。更加可怕的是,随着工业的发展,水污染成了一个严重的问题。

此外,浪费水的现象也十分严重。只要你稍作留意,就经常能见到细细流淌的水龙头,听到哗啦啦的流水声,而我们却都熟视无睹,习以为常!但是,同学们有没有想过,那些缺水的城市,人民的生活是多么的不方便;有没有想过,非洲一些国家的人民在饮用着遭受污染的水;有没有想过,如果有一天,我们的用水也成为困难,那该怎么办呢?

水是生命之源。人类的生存和发展离不开水。同学们,让我们树立“节约水光荣、浪费水可耻”的思想,养成“节约每一滴水,从我做起,从现在做起”的良好习惯,不但自己节约用水,还要监督我们的爸爸、妈妈、爷爷、奶奶也来节约用水,用我们的实际行动来珍爱生命之水!

As we know, water is very important to man, we cant live without water。 The amount of water which is suitable to drink is less and less。 But some people dont care about it。 They waste a lot of water in their daily life。 Even worse, they pour dirty water into rivers。 They throw rubbish into rivers, too。 Many rivers and lakes are seriously polluted。 Something must be done to stop the pollution。 And I think its a great shame to waste while millions are in great need of water。 I think what we can do is that we have to save every drop of water as possible as we can。 For example, we must turn off the tap immediately after we use it。 We can use a basin to wash our hands and faces。 Its also a good idea to encourage my friends and family members to join me! Only in this way can we live happily。 If we dont save water, the last drop of water will be a tear—drop of us。 I believe if everyone makes a little effort, we can make a big difference。

In modern society, pressure is ubiquitous. As students, we have to endure

the pressure from examination, from homework and from our parents’

expectations.As workers, people are faced with the pressure from deadline, from

difficulties and from finance and so on. Here I would like to give some

suggestions about relieving pressure.

First of all, to confide to others is an efficient way for relieving

pressure. When we feel so anxious and worried that we cannot continue to work or

study, go to talk with our friends or family members and we will get some relief

and feel better. Second, to do some exercises is another way to relieve

pressure. If we are under pressure for a long time, doing some exercises can

make us refreshed and regain power to continue our task. Finally, another common

way for women to relieve pressure is to cry. The effect of crying is the similar

as the effect of confiding to others. After crying, we would find that we are

relaxed and then we have spirit to fight against difficulties again.

In a word, there are many ways to relieve our pressure. But the most

important point is that if we cannot solve the problem at once, we need to call

off our attention from the pressure we are faced with to other things. Only in

this way we would not be entangled with the pressure for a long time.

篇20:海洋水盐分的英语作文

全文共 2377 字

+ 加入清单

盐度如果我们分析海水的盐度,会发现地区间只有轻微的变化,然而有些小的变化是重要的。

导致海洋的盐度变化的基本过程有三个,其中之一是通过蒸发的方式即把液态水转化为水蒸气来减少海洋中的水分。

这样由于盐留了下来,所以盐度增大。

当然,如果这种方式走向极端,将会余下白色的盐晶体。与蒸发相反的是降水,如降雨,由此水被加入海中,海水被稀释,从而盐度降低。

这种情形会发生在大量降雨的地区,或江河入海岸处。因此,盐度通过蒸发减少水分而上升或通过降水或径流增加淡水成分而下降。一般来说,在阳光很

强烈的热带地区,海水的盐度略高于世界上其它没有热带那样多的蒸发的地区。同理,在江河稀释海水的海岸地带,海水盐度略低于其它海区。

第三个可以变更盐度的过程与海洋中冰的形成和融化有关。海水冻结时,溶于其中的物质被留了下来。这样,在新形成的海

水冰面的正下方的海水比在冰形成之前有更高的盐度。

当然,当冰融化的时候,会降低周围水中的盐度。

在南极洲边缘的威德尔海中,结冰过程增加低温海水的盐度,从而形成了浓度最大的海水。这些大密度的海水下沉,可以在世界海洋的深水域发现。

if the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. nevertheless, some of these small changes are important. there are three basic processes that cause a change in oceanic salinity. one of these is the subtraction of water from the ocean by means of evaporation--- conversion of liquid water to water vapor. in this manner the salinity is increased, since the salts stay behind. if this is carried to the etreme, of course, white crystals of salt would be left behind.

the opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. here the ocean is being diluted so that the salinity is decreased. this may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.a third process by which salinity may be altered is associated with the formation and melting of sea ice. when sea water is frozen, the dissolved materials are left behind. in this manner, sea water directly materials are left behind.

in this manner, sea water directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.in the weddell sea antarctica, the densest water in the oceans is formed as a result of this freezing process, which increases the salinity of cold water. this heavy water sinks and is found in the deeper portions of the oceans of the world.
