海水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.

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。

Water is one of the most valuable resource in the world, is the ideal liquid to sustain life. Mammals in vivo is between 60% and 65% water, two-thirds of the human body weight, 99% of the brain, bones are about 44% water. Lack of water, the human and the earth will not survive, forests will disappear, the plant will perish, the earth will appear the boundless desert, signs of life will disappear.

Currently the worlds fresh water accounts for only 2.5% of the total water resources, of which more than 70% is frozen in the arctic and Antarctic ice sheets, and it is difficult to use the snow on the mountain glaciers and permafrost, 87% of the fresh water resources is difficult to use. Humans really able to take advantage of the freshwater resources is part of the rivers and lakes, and groundwater, accounts for about 0.26% of the earths water.

Given the global freshwater resources shortage, not only will soon fall into the predicament of the water shortage in many countries, economic development will be limited, on January 18, 1993, the 47th United Nations general assembly resolution, determine the annual March 22 as "world water day". After the water act of the Peoples Republic of China promulgated in 1988, the ministry of water resources is to determine the annual July 1 to 7 as "Chinas water week", considering the "world water day" and "China water week" the purpose and content of basic same, therefore, starting from 1994, change the time of "Chinas water week" to the annual March 22 to 28, time coincidence, make a campaign more highlights the theme of "world water day".

水是世界上最宝贵的一种资源，也是维持生命的理想液体。哺乳动物体内60%至65%是水，人类体重的2/3、大脑的99%、骨骼的44%也都是水。缺了水，人类和地球将不能存活，森林将不复存在，植物将灭亡，地球上将出现无边的沙漠，生命的迹象将消失。

目前全世界的淡水资源仅占其总水量的2.5%，其中70%以上被冻结在南极和北极的冰盖中，加上难以利用的高山冰川和永冻积雪，有87%的淡水资源难以利用。人类真正能够利用的淡水资源是江河湖泊和地下水中的一部分，约占地球总水量的0.26%。

鉴于全球淡水资源不仅短缺、许多国家将很快陷入缺水的困境，经济发展将受到限制，1993年1月18日，第47届联合国大会作出决议，确定每年的3月22日为“世界水日”。1988年《中华人民共和国水法》颁布后，水利部即确定每年的7月1日至7日为“中国水周”，考虑到“世界水日”与“中国水周”的主旨和内容基本相同，故从1994年开始，把“中国水周”的时间改为每年的3月22日至28日，时间重合，使宣传活动更加突出“世界水日”的主题。

Yesterday, I go to the bathroom in the morning up and have a look at when I asked: "mom I got up early," mother said: "not you got up early, but the day was held up by the fog," I think of today will not again see the puzzled.

昨天，早上我上厕所的时候起来一看我问：“妈妈我是不是起早了，”妈妈说：“不是你起早了，而是天被雾霾挡住了，”我疑惑不解的想着今天不会又看不见吧。

然后我就急急忙忙的拿了一盒饼干去作文班上学，我刚一下电梯，还没来得及戴上口罩我就闻到了一种刺鼻的味道，我就立马戴上口罩，出去一看，整个天黑乎乎的，连树叶上面都灰，转了我们小区的花园，我才知道天气是被人们污染、鞭炮的浓烟污染、尘土污染、汽车的浓烟污染的，然后我就骑上自行车，很快的赶往作文学校，这一路上我发现路上的行人很少，大多都是开车的，前面的车把浓烟喷射到后面的车玻璃上，车玻璃直接没法擦了，我们今天的作文是没法写了，但是我们见天可以玩了，我们就给各自的家长打了电话让他们接我回家，只有我一个人孤零零的骑着自行车回家。

"XX school student collective food poisoning", "XX place bleak look-out collapse", "XX place again there was a traffic accident"... Life, always hear or see some strange, let person sigh of accident, one after another tragedy always constantly in front of us.

Danger is in our each persons side, sometimes is so near to us. "Lucky" I experienced this once. That, I come home from school, saw this scene: a child was playing in the road, no attention paid to the coming danger, a large truck coming toward her. Others shouted, looking back, the childrens truck, immediately panic, his face pale, legs a soft, straight down to the ground, big trucks the emergency brake, but it was too late, the boy has been under pressure in the car. People suddenly gave a shout, some with burying his face in his hands, did not dare to look down, some by the sudden scene scared silly, just stand in situ. "Another child forever left the world", is really sad. However, when people return to absolute being, has found that children had miraculously stood up, not a little damage.

Many risks ah, had a narrow escape. Thanks to the girl in the middle of front, thanks to the cars chassis is high, if a little partial, if the body again a little bit low, the consequence is unimaginable.

Security, is inseparable from a topic, we will never pay attention to safety, is we all know the truth. But safety accidents happen every day, and constantly increasing, every day in the heartbreaking tragedy. Safety first, with safety, we floral life to blossom. With safety, we can happily spend the youth, life for everyone only once, lost, will not come back. Whenever we up and down the stairs, a little light, quiet a little. Whenever we cross the road, look around first, then walked briskly, whenever we school, want to go home as soon as possible, dont play on the side of the road.

Life is great, but it is fragile. We should cherish life, safety first!

“XX学校学生集体食物中毒”，“XX地方煤井塌陷”，“XX地方又发生了交通事故”……生活中，总会听到或看到这样一些令人惊心，让人叹息的事故发生，一个又一个地悲剧总会在我们面前不断地上演。

危险就在我们每个人的身边，有时离我们是那么近。我“有幸”经历了这么一次。那次，我放学回家，看到了这样一幕：一个孩子正在马路中央玩耍，丝毫没有注意到即将到来的危险，一辆大卡车朝她驶来。旁人高喊一声，那个孩子回头一看，是卡车，顿时惊恐万分，脸色发白，腿一软，人直直地倒在地上，大卡车紧急刹车，可是，已经迟了，那个孩子已被压在车下。人群顿时发出一阵惊呼，有的用双手捂住脸，不敢往下看，有的被突如其来的场面吓傻了，呆呆地立在原地。“又一个孩子永远地离开了这个世界”，真是悲哀。可是，当人们回过神来后，却发现小孩奇迹般地站了起来，没有受到一点伤害。

多险呀，真是死里逃生。幸亏了那女孩倒在了车前的正中间，幸亏了那车的底盘高，如果再偏一点，如果车身再低一点，那后果不堪设想。

安全，是我们永远离不开的一个话题，注意安全，是我们每个人都懂的道理。但是安全事故还是每天都在发生，而且不断地增多，天天都在上演那令人心碎的悲剧。安全第一呀，有了安全，我们如花般的生命才能绽放。有了安全，我们才能开开心心地度过青春年华，生命对每个人来说只有一次，失去了，就永远回不来了。每当我们上下楼梯，轻一点儿，静一点儿。每当我们横穿马路，先左右看一下，再轻快地走过，每当我们放学时，要尽快回家，不要在路边玩耍。

生命是伟大的，但又是脆弱的。我们要珍惜生命，安全第一!

Water is very important to us. If you dont have water for three days, you will die. We can use water for flowers, swimming, washing and many different things. We use it to cook, make electricity, and put out fires and so on. We use millions of liters of water every day.

水对我们很重要。如果没有水，不出三天，你就会死的。我们可以用水游泳，洗涤和做许多不同的事情。我们用它做饭，发电，和扑灭火灾等。我们每天使用数百万公升的水。

Do you know how does the water come to your home? It travels through water pipes. Some are long and wide but some are short and narrow. Then the water travels through the water pipes to the reservoirs. Then it travels through the water pipes to the river and to the special factories that purify the water. When the water is purified, we can drink it. Please dont leave garbage in the water on which we line, and keep the water clean.

你知道水是如何来到您的家吗?它穿越水管。有些是长而宽的，但有些是短而细的。然后通过水管到达水库。然后通过河流和专门用来净化水的工厂。当水净化后，我们可以喝它了。请不要丢垃圾到水中，因为水是我们的生命线，我们要保持水的清洁。

This morning, I got up, ate breakfast, go to typically exposes.

Downstairs to open the door a look, and outside is all the mist, and fog is very thick. Into the mist, a cool moist air. I sit on the car, ready to learn. In the fog to stay for a long time, some naughty little drops of water on my clothes.

今天早上，我起了床，吃完了早饭，就去上特长班了。

下楼打开门一看，外面全都是雾，而且雾还很浓。走进雾里，一股清冷潮湿的空气扑来。我坐上了车子，准备去学特长。在雾里待久了，一些顽皮的小水滴镶嵌在我的衣服上。我向四周望了望，顿时想出了一个奇特的想法：我好像走进了《西游记》中的瑶池?这雾像是走进了神话一般!雾的景象真美呀!路上，姥爷问我：“这是雾还是霾?”我说这是雾，姥爷又说：“不对，是雾和霾都有。”

但雾霾对身体有害。雾霾天气不仅影响市民出行，也对市民的身体健康也有影响。雾霾天气空气流通性差，空气质量也差，雾霾中的有害物质会引发一些疾病，对健康人会轻微的器官损伤，还咳嗽、痰多……

所以，雾霾天气要少出门，出门的话要戴口罩、饮食清淡多喝水、雾霾天气少开窗……

雾霾跟我们的污染有关系，所以我们要珍惜大自然。

Thanks to my parents, I have been to many places. I feel so lucky to

witness the scenery by my eyes. I love to travel since I was very small. I have

made up my mind that I must continue my journey on my own. As I grow up, I have

planned some trips and learned a lot.

groups, which is very convenient. The companies plan everything for them, and

they just need to follow the schedules. But as for me, I only enjoytraveling

freely, so I will scan a lot of information and select the useful message. I

learn the history and culture of the countries and get to know all kinds of

applications.

The most important thing of travel is to broaden my vision. When my friends

talk about the beautiful places from the textbook, I will tell them that I have

been there and can give them my opinion. The way I talk and the knowledge I

offer to them make me stand out and I am so proud of myself.
