Boundless sea to look forward to, give people the beauty, give a person

warm motherly love.

The sea is like a poem; it jumps; like a picture, rich in meaning; and like

a symphony, vast and mighty...... It is like a mirror; sometimes calm, sometimes

filled with rage, overwhelming, to sail the boat overturned. In my mind, the sea

is blue world, is also the cradle of life. Pregnant with many free and small

life. The sea is so mysterious, so charming!

Now the sea has changed. The sea is no longer clear, it becomes muddy and

dirty. Washed up on the beach, left is no longer alive and kicking the fish

shrimp, instead of the piles of rubbish, but also mixed with a lot of dead fish

shrimp, stinking. Why is that? Its all because of us. When people admire the

beauty of the seaside, they throw the foul rubbish into the sea. There are also

people living on the beach, the toilet drain pipe to the bottom of the sea.

Whats worse is that the factory waste water flows into the sea in large stocks,

and the sea is dyed in a strange color. Led to the birth of a lot of lack of

brains, low IQ infants, our next generation - bright eyes [voice tender], the

face of the next generation of red, will never see the beautiful blue sea.

Someone once did an experiment. He compared a basin of water to the ocean,

and dropped a drop of ink into the sea. Immediately, the ink slowly spread out,

became shallow and disappeared. The sea water was almost as clean as ever. If

the ink kept dropping, the color of the sea would be deeper and darker, and

eventually it would become a basin of black water. 6 billion people on the earth

produce large quantities of living waste water and industrial pollution every

day. Like ink, it has been injected into the clear sea water. It has become a

polluted lake.

To the health of our human beings, to see the beautiful blue sea for our

children and grandchildren. Let us act now, love the ocean as much as we love

life, and love the common blue home of mankind.

If we give up hope, we can’t see the good things that will come around. Keeping the hope is very important, it will help us to overcome the difficulty.

昨晚，我感到很无聊，所以我开始看电影，我的朋友叫我去看《迷雾》，她说那部电影很震惊，我很期待看。《迷雾》是一部恐怖片，讲述了一场大雾笼罩国家，人们挣扎着在这个世界上和怪物存活，最后，由于是在无路可退，男主人公杀死了他的儿子，为了让他解脱，只是过了一会，救援队就来了。对于男主人公来说结局是多么的绝望啊，如果他坚持一会，事情就会不一样了。故事告诉人们永远都不要放弃希望，谁知道下一秒钟会发生什么事情呢。如果我们放弃希望，我们就看不到接下来的事情。怀抱希望是很重要的，它能让我们克服困难。

The simplest water pollution definition would be any contamination of water bodies with some pollutant(s) that changes physical,biological,and chemical conditions of any body of water making this water harmful for environment and surrounding ecosystems.

Water pollution occurs once too much pollutants (mostly in form of different waste) are discharged directly or indirectly into water bodies.Water pollution does not only cause great environmental damage but is also the leading worldwide cause of deaths and diseases responsible for the deaths of more than 14,000 people each day,mostly in developing countries.

Many people are not aware that water pollution is serious problem in almost all parts of the world,and not just in third world countries like some choose to believe.In fact many experts will tell you that reality is completely different than the common belief,and that actually water pollution problem is already out of control.

Water pollution problem is in most cases connected with the careless handling of chemical agents,toxins introduced into our water through industrial dumping,and farm runoff.All these factors make our water unsafe to drink.

Oceans becoming more acidicThe worlds oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.

Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.

Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.

傍晚，我漫步在沙滩上。海，在我的脚下沉吟着，就如诗人一般。那声音仿佛是朦胧的月色和玫瑰的晨雾那样温柔；又像是情人的蜜语那样芳醇；低低地，轻轻地，像是微风拂过琴弦，又像是落花飘落水面。此时，我的心中幻想起未来海洋的模样：

白天，海面水平如镜，宛如一个恬静温柔的少女。干净的海面犹如湛蓝的天空，一碧万顷，一望无垠。人们忙碌的身影，人们充实的身影，人们匆匆奔走的身影，无一不倒影在海面上，仿佛海里有另一个人类世界。天色渐渐昏暗，夕阳顿时变得橙澄澄的，把大海和天空都赢得金灿灿的，美不胜收。微微的海风，带着一丝丝凉意，轻轻拂过人们的脸庞。月亮姐姐出来了，把忙了一天的太阳公公送走了。今晚的月色为何这样明？海浪已经蠢蠢欲动，拍打着岸边的礁石。海终于愤怒了！他咆哮着袭击过来，猛烈地冲向岸边，冲进了岩石的空隙中，又拨剌着岩石的堡垒，发出雷鸣般的轰响。

“当……当……”海洋时钟缓慢而又有力的敲打着，人们纷纷从梦境中醒来，朝着巨浪奔跑过去，欢呼着，蹦跳着。“扑通”，“扑通”的声响，一声接着一声。大海上出现了一个漩涡，人们高兴地跳进漩涡，进入海底世界。

陆地上是昏暗的，高楼大厦布满了人口密度众多的地方。而海洋里却是另一番模样：明晃晃的世界，似乎从来不知道黑暗是怎样的，湛蓝湛蓝的海水，仿佛把人类世界也给变成湛蓝湛蓝的了，各种人类曾经从来没有见过的海底生物，海底的礁石也毫不软弱，一尘不染，五光十色，光滑美丽。人类在海洋里吃的是高蛋白食品，喝的是含有丰富矿物质的海水，用的是光滑美丽的礁石做成的家具——啊，人类快和海洋融为一体了！

海面渐渐平静，海底也渐渐昏暗。原来是第二天清晨的阳光来迎接人们了！人们纷纷从海底游向岸边，心中带着一丝丝的遗憾，但又期盼着今日的夜晚。

时间不早了，我从幻想中醒来，可我还想再一次幻想。啊，未来，我对你充满幻想；啊，未来，我对你饱含希望！

人活着总是要有希望存在的，万一实现了呢，有希望生活处处充满生机。下面是小编为您带来的是关于希望工程英语作文相关内容，希望对您有所帮助。

If a man has hope, he will have a pursuit. Even if the hope is destroyed, what is the meaning of the mans life? "Hope Project" brings hope to those who have no hope.

The "Hope Project" will set materials distributed to where it is most needed, so that the children read a book, and the other children can enjoy the same rights, "those donors hope project, they do their best to help others, their dedication is worthy of our study.

We should correct our attitude towards "project hope". There is such a story: a white collar America, each work will give a beggar at the gate of the $15, gradually give the beggar less money, turned into a $10, $5, the beggar was puzzled and asked: "why do you give me less and less money?" The white collar said, "when I gave you 15 dollars, I was still single. When I gave you 10 dollars, I had a girlfriend. When I gave you 5 dollars, I already had a baby."." The beggar listened, and roared, "why did you pay my money to support your family?"!" See this a little funny, but they think the beggar really shameless, the white-collar workers to help him, he did not even try to say thanks, take the help as behoove thing, really confusing.

In other words, what would you do if you saw the American white-collar worker as a "project of hope" and the beggar as a sponsor? Will be like that beggar? Or...?

As a teenager, as a quality of youth, we should learn Thanksgiving, learn to sacrifice, but for us, is the first study, funded by us, we enjoyed life, our life is full of hope, because of project hope, there is hope, we take I grow in gratitude, the gratitude we give, will we have dedicated to the people who need help, "Project Hope" spirit will be handed down from age to age.

Hope project gave us hope, in the way of growth, let us have Thanksgiving, with the pursuit, we will not be lonely.

人有了希望才会有追求，如果连希望都破灭了那人活着还有什么意思，“希望工程”就是给那些没有希望的人带来希望。

“希望工程”将所集物资发放到最需要它的地方，使那些失学儿童有书读，可以享受和其他孩子一样的权利，“希望工程”的那些捐助者们，他们尽自己所能帮助着别人，他们的奉献精神值得我们学习。

对于“希望工程”我们要端正自己的态度。有这样一个故事：美国一位白领，每次下班都会给门口的一位乞丐15美元，渐渐地给乞丐的钱少了，变成了10美元，后来变成了5美元，这个乞丐就疑惑地问：“为什么你给我的钱越来越少？”那位白领说：“我给你15美元时，我还是个单身，给你10美元时，我有女友了，当给你5美元时，我已经有了孩子。”那乞丐听了大怒，吼道：“你为什么花我的钱养你的家！”看到这不免有点好笑，但转而就觉得这个乞丐真的好无耻，那位白领帮助了他，他不言谢也就算了，尽把别人的帮助当成了理所当然的事，真的很让人费解。

换而言之，如果把那位美国白领看作是“希望工程”，而那个乞丐就是被资助的人，你会怎么做？会像那个乞丐一样？还是……？

做为青少年，做为一个有素质的青少年，我们要学会感恩，学会奉献，但对我们来说，学习是第一位，我们受着资助，我们享受着生活，我们的生活充满了希望，因为希望工程的存在，就有了希望的存在，我们带着希望在感恩中成长，在感恩中我们学会奉献，将我们所拥有的奉献给那些需要帮助的人，将“希望工程”的精神代代相传。

希望工程，给了我们希望，在成长的路上让我们拥有感恩，有了追求，我们才不会寂寞。

a responsibility to reduce sea pollution.

I need to describe the problem. Our ship currently dumps all its rubbish

into the sea.Its easy to result in huge endanger. First of all, Non-organic

and whales cannot digest them. Secondly some rubbish is inherently toxic.

system of disposing of rubbish for instance. We ought to store rubbish. Next, we

are supposed to make ships environmentally and friendly. A case in point is that

we should stop providing plastic bags.

We must act now before it is too late!

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.

In the vast ocean live many creatures with great intellectual and physical capacities.Dolphin is one of those great creatures,whose capacities to think and move at an astounding rate puzzle those who study their behaviors,Dolphins possess something that makes them different from all the other sea creatures.It is not strength or speed but the size of their brains.Dolphin s brain is almost the same size as that found in the human head.They live for a ling time.

Dolphins babies are born in the water.They can grow up to three and a half meters long.

Dolopins use sound to help them find their way,look for their food and talk with each other.Sound is just like their eyes and mouths.

.There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities. To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources

and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.

In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves

In the animal kingdom, both predators and prey species utilize one of two things to survive—stealth or speed. Both on land and beneath the sea, those who master either evasion or capture through these methods will thrive, living to reproduce and achieve the unspoken directive of their species. While stealth—through camouflage or evasion—is common, perhaps the most thrilling feature of many of the animals we find in the ocean are the fantastic speeds that can not only be achieved, but often maintained for long periods of time.Speed represents a tremendous expenditure, an investment of energy that must be replenished via consumed calories. Therefore, any observer should marvel not only at the existence of this trait, but also at the bounty of an ecosystem and the ability of individuals to draw their needs from that system. Their existence is a reflection of the fantastic diversity and abundance of our oceans. Here are ten of the fastest aquatic animals—both predator and prey.

动物世界里，不管是捕食者还是被捕食者，暗袭和速度是它们赖以生存的两大法宝。许多陆地和海洋生物正是通过这两项技能得以繁衍成长，维持在自然界中的生存地位。对于暗袭，大多数动物拥有独特的保护色和逃遁技巧，以此捕食或躲避天敌。然而，在海洋世界，失去遮蔽物和光线，速度才是生存王道。许多海洋生物爆发力惊人，不仅可以很快达到超高时速，更为赞叹的是凭借其惊人耐力能游行数小时。长时间竞速意味着巨大的体能消耗，需要通过摄入大量卡路里补充体力。因此，人们不仅会对这一特点感到惊奇，更会对它们身处生物系统底部却能以个体能力获得所需而惊叹不已。它们的存在就是海洋多样性及丰富性的最好体现。

The seas and oceans receive the brunt of human waste, whether it is by deliberate dumping or by natural run-off from the land.

In fact over 80% of all marine pollution comes from land-based activities and many pollutants are deposited in estuaries and coastal waters. Here the pollutants enter marine food chains, building up their concentrations until they reach toxic levels. It often takes human casualties to alert us to pollution and such was the case in Minimata Bay in Japan when many people died as a result of a pollutant building up in food chains. A factory was discharging waste containing methyl mercury in low concentrations into the sea and as this pollutant passed through food chains it became more concentrated in the tissues of marine organisms until it reached toxic levels.

As a consequence 649 people died from eating fish and shellfish contaminated with mercury and 3500 people suffered from mercury poisoning.
