+ 加入清单“小时候,妈妈对我讲,大海就是我故乡,海边出生,海里成长,大海啊大海,是我生长的地方……”回忆起《大海啊故乡》这首歌时,我就想起了我们生命的摇篮,文化历史的根源,苍茫蔚蓝的蓝色宝库——海洋,它是21世纪的希望,可正面临着前所未有的危机!
海洋里生活着各种各样的生物,蕴含着丰富的宝藏,有着神秘的色彩和未知的奥秘。海洋是一个庞大的家族,在这个家族里,居住着许许多多、形态各异的“居民”:“海岸守护神”——红树林,“夺命仙子”——水母,大海里的“鱼医生”——霓虹刺鳍鱼……一切是多么美好,它们都是共筑海洋的一份子,也是建设和平家园的一员,少了它们其中的一个,海洋就不会这么灿烂了。同时,海洋也是一个巨大的“蓝色药库”、“蓝色牧场”。它的色彩、它的神秘无时无刻不在吸引着我们去探索。
我从小对海洋中的生物充满好奇。比如在我的印象中,鲨鱼是凶恶的。通过阅读,我了解到事实上它的确如此。鲸鲨个头最大,体长约25米,体重可达80吨,是个庞然大物。最小的鲨鱼是侏儒角鲨,长20—27cm,小到都可以放在手上了。鲨鱼算是大海里的高等生物,因为它是哺乳动物,以肉食为食。有时还会猎食海龟、螃蟹等。在觅食时一旦发现目标就会立即出击吞掉。这与鲨鱼灵敏的嗅觉和敏锐的洞察能力是分不开的。它对血腥味非常敏感,哪怕是30米以外的一滴血,都能闻到,凡是被它盯梢的猎物,都是很难逃脱的。可是,别看鲨鱼凶很危险,不过,它可全身是宝呢!鲨鱼的肝脏含有丰富的维A、维D,因此,科学家们一直在研究鲨鱼身上的奥秘,希望可以造福人类。
我们美丽的地球只有一个,我们美好的家园只有一个。同样,我们的海洋也只有一个,让明天的海洋更加灿烂!我们一起携手保护海洋吧!

Dont know what those people long is the heart of stone, if left unchecked, we can no longer hear birds schools of thought contend, and cant see the fish live the bottom of the sea, many animals will become "according to historical records". The world will no longer be rich and colorful, the world will only greedy human lonely and sad. This is the tragedy of the entire human race.
Have a word said good, protect animals is to love ourselves, any kind of animal in nature are one part of the food chain, a ring is indispensable, the lack of any one ring will upset the balance of nature, to suffer or ourselves, many animals are friends of human beings, human beings are not often divides into the animal beneficial insects and pests? If beneficial insects is destroyed, it is how a situation? If extinction beneficial insects pests also ceased to exist, the survival of the animal extinction is closely related to our life.
To protect animals, cherish life, is that we call, from the bottom of his heart.

你热爱动物吗?动物和人类一样都是我们这个美丽星球的拥有者,都有权利在这个星球上自由的生存,都有权利享有大自然赋予我们的一切,这是我们共同的家园。
然而在有些人眼中,这些动物不过是一些任人宰割、没有生命、没有感情的东西。它们不过是餐桌上的美味或能换取金钱的物品,人们为了皮衣和食品杀死各种飞禽走兽,为了所谓“口福”大量捕杀贩卖山珍野味,满山的捕鸟网,遍野的捕兽套,令人触目惊心的动物残骸,诸如此类的报道屡见不鲜,不绝于声。致使动物种类大幅减少,有些动物已经灭绝或濒于灭绝,太残忍了。不知道那些人长的是怎样的铁石心肠,如果任其发展下去,我们再也听不到百鸟争鸣,再看不到鱼翔海底,许多动物将成为“据史料记载”。这个世界将不再丰富多彩,这个世界将只剩下贪婪人类的孤独和凄凉。这是整个人类的悲哀。
有一句话说的好,保护动物就等于爱护我们自己,大自然中的任何一种动物都是食物链的一环,一环不可缺少,缺少任何一环都会打乱自然界的平衡,遭殃的还是我们自己,许多动物都是人类的朋友,人类自己不是经常把动物分为益虫和害虫吗?如果益虫都灭绝了,那会是怎样一种情况呢?如果害虫灭绝益虫也不复存在,动物的生存灭绝与我们的生活密切相关。
保护动物,珍惜生命,是我们从心底发出的呼唤。我们要从身边的小事做起,爱护小动物,爱护弱小生命,拒绝食用野生动物,拒绝穿戴使用兽皮、兽骨做的衣服,饰品和用品。坚决抵制残害动物的行为,为我们和动物共同营造一个和谐共存的家园。

+ 加入清单“大丰收,大丰收啦!”一个渔民高叫着,高兴得竟像个孩子似地跳了起来。不一会儿,满舱的鱼虾活蹦乱跳,平静的海面上洋溢着从四面八方传来的渔民的欢笑………
如今,像这种“鱼虾满舱”的场面已经很少见了。当今的市面上,就是最常见的鱼一斤起码也要几十元,海洋的污染愈加严重,这使得海洋资源在逐渐地枯竭,海产品的减产、价格的上涨,不正说明了这一点吗?
在天灾层出不穷的今天,人类对海洋的污染往往并非出自本意,但造成的影响却是始料不及的。英国石油公司开采石油时,由于钻井平台的爆炸,造成原油泄漏,令墨西哥湾海域9900平方千米的海水受到严重污染,使得成千上万的海鸟浸泡在油污中动弹不得,在饥饿和痛苦中死去,更使得无数鱼儿中毒而亡;而日本的地震海啸引发的核泄露对海洋造成的污染则更加严重……
正所谓海纳百川,大海之所以能如此浩瀚,正是因为那些小河小溪汇入长江大河再奔流入海。如果不从源头解决污染问题,那么不管人们再怎么清理海洋,总还会有污水流入海中,人们的一切努力也都会变成徒劳。现在,小溪小河往往都是污染严重,要么就是成了人们倾倒垃圾的场所,要么就是堆满了农药罐。要在有人居住的区域内找到清澈见底的小溪,在今日可谓是难上加难啊!
不管怎样,保护海洋不是靠个人的力量能实现的,保护海洋还得靠全人类的共同努力。我不希望在未来的某一天,我们的子孙后代只能通过影像资料来想象大海的浩瀚与宽广。
这不只是一个小学生的心愿,也是全人类的心愿,不是吗?

+ 加入清单It seems we are living in the conflict between modern and traditional cultures every day. Hearing the blaring of horns the moment you step out of your house, seeing the so called "pop" the moment you open your eyes, you cant help thinking, "Will the traditional culture be gradually lost?"
Many people believe so. They may put right in front of you all the evidences they can dig out. They may argue that people are rushing to restaurants instead of cooking at home, listening to pop music but not traditional, wearing in a way people couldnt imagine ten years ago. Modern people like the air of freedom, not to be restrained by traditions. They offer this long list, only trying to confirm that this world is full of fashion,competition and temptation and the traditional culture is fading
and will be lost at last.
Though we are now living in a world in which undeclared aggression, war, hypocrisy, chicanery, anarchy are part of our daily life. Though this is a skeptical age, and our faith has weakened, our confidence in some aspects of the traditional culture should and would never be lost.
Wouldnt you agree that our traditional culture is always credited with modesty, politeness and respectfulness, which have always been treasured for more than five thousand years?Even in this modern world, people still admire those with good manners, those who are polite to others or respectful to old people.
Wouldnt you agree that our Chinese traditional music is beautiful and artistic and our Chinese tea culture is always an appealing treasure to people around the world?
So there may just be some changes in our lifestyle or our attitudes towards life, but little change occurs to some fundamental aspects of our traditional culture that people still treasure in heart.

篇12:怎样保护树的英语作文
全文共 3210 字
+ 加入清单Each year, people burn or cut down 143,000 square kilometers (55,000 square miles) of the forest. People who burn or cut down trees do it for different reasons: farmers cut down trees in order to get more fertilize lands to grow rice or vegetables, and use the woods as fuel. Timber companies cut down trees and turn them into furniture or paper productions. As to goal miners, they remove the forests to find out whether there are goal underground.
每一年,人们都会砍伐14.3万平方千米的森林(约5.5万平方英里)。人们砍伐树木出于种种原因:农民们为了得到更肥沃的空地来种植大米蔬菜,砍下的树木用来取火。木材公司用树木来制作家具或是各类纸制品。至于那些开采煤矿的人,把树木砍掉就是为了检测是否有煤矿在下面。
However, many of us fail to realize that forests are the lungs of the earth. When we cut down trees, we also push ourselves in to a dangerous situation. That is the global warming. When you come to think about it, there are only few ways to solve these negative effects: stop cutting down trees blindly; try to find some clear energy that can replace oil and coal. But these solutions can be impractical to some degreed.
然而,我们中的许多人都没有意识到树木等同于地球的“肺部”。当我们砍伐树木时,我们就把自己推入一个危险的境地——会引起全球气候变暖。想到这些,只有为数不多的几个办法可以解决这个问题:停止盲目地砍伐树木;寻找可以代替石油和煤矿的新能源。但是,就目前来看,这几个策略并不可行。
Why trees can be so important to the whole nature? First of all, trees are the habitat of many animals. When we cut down trees, we not only destroy animals’ habitats but also ourselves. We just gradually destroy natural links. The result is that many spices of animals and plants are dying out. Secondly, cutting down trees cause global warming, to some degree. Naturalists compare forest to human’s lungs. The forests absorb the carbon dioxide and other gas that cause global warming, and then give off the oxygen that good for the human beings and other living creatures. It’s refreshed the air as well as reduced the noise. If the air quality is bad, people may die from cancers, or the new diseases for which they have no immunity. Forests also play an important role in the prevention of natural disasters. Warmer temperatures cause water to expand and also create more water by melting polar ice caps. That’s to say, the nations which near the ocean may have been flooded by the water. But the forests can prevent water loss and soil erosion, and cool off the global temperatures. It’s the key to keep the balance of the nature.
为什么树木对整个生态环境都如此重要呢?首先,树木是小动物们的家园。当我们砍伐树木时,我们不仅仅毁掉了它们的家,也毁掉了自己的。一步步的,我们慢慢分解了整个生态链,所造成的结果就是大批的动植物种类灭绝。其二,砍伐树木在某种程度上造成全球变暖。生态学家把森林比作人类的肺。森林能够吸收二氧化碳和其他引起气候变暖的温室气体,然后转化成氧气供地球上的生物呼吸。树木不仅能净化空气,也能减少噪音。如果空气质量下降,那么人们就有可能死于肺癌,或者是其他致命菌。森林在预防疾病的过程中起到了重要的角色。气温的上升导致北极的冰层融化,水平面上升。也就是说,临海的城市也许会被海水淹没。但是森林就能够阻止水土流失,使气温下降。它是保证全球生态平衡的关键。
Sometimes people only care about money making; they don’t care about the price we pay for the pollution. When the disaster is around the corner, we may be afraid and frustrated. The earth, on which our economies have always been based, is suddenly threatening our existence. All we hope that is this overpopulated, over industrialized planet can carry on for a longer time. And maybe, it’s time for us to realize that we should protect the earth, stop cutting down trees blindly and madly.
有时候人们只关心挣钱,却对我们所付出的代价不管不问。当灾难来临时,我们会害怕、会彷徨。我们赖以生存的地球,却突然变成了威胁我们生命的东西。我们只希望,在这个人口过度、工业过度的星球能继续撑下去。也许,是时候我们应该保护地球,停止盲目疯狂地砍伐树木了。

Why should people care? Because we need animals, and because once they are gone, there will never be any more。Animals are more than just beautiful or interesting.They are more than just a source of food.Every animal has its place in the balance of nature.Destroying one kind of animal can create many problems.For example, when farmers killed large numbers of hawks, the farmers stores of corn and grain were destroyed by rats and mice.Why? Because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly。
Luckily, some people are working to help save the animals.Some groups raise money to let people know about the problem.And they try to get the governments to pass laws protecting animals in danger.Quite a few countries have passed laws.These laws forbid the killing of any animal or planton the danger list.Slowly, the number of some animals in danger is growing。

篇15:海洋水盐分的英语作文
全文共 2377 字
+ 加入清单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.
