With the development of our society， energy in the world bees more and more

limited， so it is quite important for us to save energy and to protect our

environment。 As a student， there are a lot of methods we can do to save energy

at home。 For example， first， we can turn off the light as well as other

appliances when we are not using them。 Second， recycle the waste water， paper

and other waste so that we can reuse them。 Whats more， it is suggested to use

public transportation more instead of private cars.

Above all， everyone can make a great contribution to our environment。 I

hope I can learn more to develop new and clear energy， like energy from the wind

and solar.

A breakthrough in the provision of energy from the sun for the European Economic Community (EEC. could be brought forward by up to two decades.if a modest increase could be provided m e EEC s research effort in this field according to the senior EEC scientists engaged in experiments in solar energy at EECs scientific laboratories at Ispranear Milan.

The senior West German scientist in charge of the Community s solar energy programme Mr. Joachim f^tittold journalists that at present levels of research spending it was most unlikely that solar energy U d Provide as much as three percent of the Community s energy requirements even after the year .But he said that with a modest increase in the present sums, devoted by the EEC to this work it possible that the breakthrough could be achieved by the end of the next decade.

Mr. Gretz calculates that if solar energy only provided three percent of the EEC s needs,thu still produce a saving of about a billion pounds in the present bill for imported energy each year believes that with the possibility of utilizing more advanced technology in this field it might be po?tiblc satisfy a much bigger share of the Communitys future energy needs.

At present the EEC spends about $2.6 millions a year on solar research at Ispraone of the ￡Ec, official joint research centers,and another $ 3 millions a year in indirect research with universities other independent bodies.

作文【一】

One day Sun Wukong together with his master and brothers was walking across a river. Suddenly his master fell off the horse by the bad smell of river water. They found the water so dirty that they could hardly breathe.

A lot of factories along the river always poured their waste water and rubbish straight into the river which made the river water polluted. In this way most of the fish in the river were killed. If the river water all over the country is polluted like this, no living things will exist in the water. Now more and more people have come to realize how serious this problem is. Our government is doing her best to take measures to fight against pollution. We expect that the water in every river will be made cleaner and cleaner before long.

作文【二】

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.

Li Hua

Dear editor,

Environmental problems are becoming more and more serious all over the world.

With the development of industry and agriculture, cars make great noises and give off poisonous gas. Because of population expansion and overdevelopment, resources has become less and less. Trees on the hills have been cut down, and waste water is being poured continuously into rivers. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to man’s existence.

We must face the situation that exists and take actions to solve our environmental problems. We hope that all these measures will be effective and bring back a healthful environment.

Can Money Buy Happiness?

Can money buy happiness? Different people have different opinions. Some

think yes, while others hold the opposite.

It is true that with enough money one can buy all the things one wants, and

live a life of comfort and security. However, it is equally true that lack of

money causes great distress. It is a common view that "money is the root of all

evil." The pursuit of money drives many people to cheat and steal. In some

places there is nothing that cannot be bought with money, resulting in corrupt

societies where everybody is miserable.

So, money does not necessarily mean happiness. It all depends on how it is

used. If we make honest and sensible use of money, it can be a stepping-stone to

happiness l Although money cannot buy happiness, it can make happiness possible

if it is employed sensibly.

金钱能买来幸福吗?

金钱能买来幸福吗?不同的人有不同的回答。有的人认为能，有的人则持相反的意见。

诚然一个人如果有足够的钱可以买到他想要的所有物品，过上舒适稳定的生活。然而，同样缺钱往往引起巨大的忧伤。人们常常认为“金钱是万恶之源”，对金钱的追求驱使许多人去骗去偷。在某些地方，没有钱买不到的东西，导致社会的腐化堕落。

所以，金钱并不一定就意味着幸福。这取决于怎样使用金钱，如果我们诚信明智地使用金钱，它将是幸福的基石。尽管金钱买不到幸福，但它可以使幸福成为可能。

All things cannot be separated from water, and fish cannot leave water.The theme is: water, the root of all things.

It is true that the seven parts of the sea are right. We are from one of the creatures in the sea, and we have the same gills of fish when we are young...Everything shows that we are connected to the sea.

Maybe we were just a little fish, but now we are the greatest humans.

The sea is so kind and mysterious, what is it that we humans are, the most intelligent creatures at the top, what are our ancestors?Its a low-grade fish or an advanced dinosaur, and everything is a mystery.

Now the sea is being developed by us, the sea ranch, the Marine oil base is so amazing.The sea gave us life, and gave us so much energy, and we?Marine oil base causes large oil spill, resulting in Marine oil pollution!What are we doing with the indiscriminate killing of whales and the salivating of shark fins?Is the environmental protection or the destruction of the ecological balance?

If the sea could wash everyones heart like a shell, there would be no creatures in the world because of our indiscriminate killing.Is it a reward that the sea is our mother, and it has created the destruction of all that it has created?No, it isnt.What else can we do when black oil covers the ocean, and when black exhaust fills the sky?The sea belongs to nature, nature belongs to us?We belong to the sea, and the sea belong to us?

What are we doing here?To kill for personal gain?Destroy for yourself?No, no, no.I do not believe that we will destroy our oceans, and I do not believe that people will despair when the oceans disappear.Because everyone is selfish.

Is it humane that the oceans have created us and destroyed us?

Although were trying to protect the environment, its too late, unless time goes backwards, unless theres a miracle, unless its all over again.I believe we can get the ocean back to our youth, and we are the smartest intelligent creatures.

Everyone, for the sake of the bright future of the sea, also protect the sea for ourselves.thank you

Earth Hour is an activity proposed by WWF to cope with global climate change, hoping that individuals, communities, businesses and governments turn off lights from 20:30 to 21:30 on the last Saturday of March each year, to show their support to action on climate change. This is a global activity that spreads all over the world quickly after it started in Sydney in 2007.Earth Hour aims to make people aware of the threat posed by climate change and make them aware of a small movement of personal and corporate will have profound impact to the environment.

“地球一小时”是由世界自然基金会应对全球气候变化发起的一项活动，希望个人，社区，企业和政府每年3月的最后一个星期六从20:30至21:30关灯，以示支持应对气候变化的行动。这是一项全球性的活动，2007年始于悉尼后就迅速传遍世界。“地球一小时”旨在使人们意识到气候变化带来的威胁，以及使他们认识到个人和企业的细小行为将对环境产生深远的影响。

n China, there are many cities taking part in this activity,especially the large cities, such as Beijing, Shanghai, and Guangzhou. Many citizens consciously turn off lights in the hour and they go out for a walk or some friends gather together to have fun. In college, students will hold some activities to attract students out of dormitory. Earth Hour has variety of activities, but the ultimate goal is the same, that is focusing on climate change and protecting the environment for individuals.

在中国，有很多城市参加了这项活动，特别是大城市，比如北京，上海和广州。很多市民在这期间有意识的关灯，他们出去散步或者和朋友聚在一起玩。在大学里，学生们也举行了一些活动吸引学生离开宿舍。地球一小时有多种活动，但是最终的目的都是一样的，都是关注气候变化和保护环境。

Many people are active in fighting against unfair treatment to colored people, women , animals and so on. Right now I am talking about fighting for respect to our environment.Though the environment doesnt have a mouth to deprecate what humans have done to her, she retaliates through action. In the early years the Chinese cut down large quantities of trees, at the source of the yellow river, which led to the disappearance of big forests and terrible floods. As a result, the Huangtu plateau which was once covered with grass and forests was turned into barrens that supported fewer plants. Another example was in several developed countries. Because many chemical factories discharged poisonous gas without filtering it, cities were covered with so much poisonous gas that people were killed by the air they breathed in. What horrible scene!What we are suffering is only a small part of what the nature once suffered. If we dont take action to show respect to the environment.

Measures should be taken to protect the environment on which we are relying. First governments should forbid destroying vegetation, rivers and lakes, oceans, as and the atmosphere as well. Second voices should be made to announce the public of the importance of protecting the environment. Third enterprises should pay special attention to the effect they have on the environment and work out solutions for the problems.

Only by changing the way we treat the environment can we get along well with it. Only by saving the environment can we save ourselves. 保护环境初三英语作文（二）

The earth scale change of climate has brought a new kind of natural disaster and the developed and complicated city system is holding a latent risk of expanding the damage artificially. Also people has been spoiling the health since the immense quantity of chemicals have been produced and already used in pursuit of convenience and various toxic substances have been produced unintentionally and accumulated in environment.

Therefore, We need some countermeasures from the viewpoint to prevent the city environment form disaster and to manage environmental risks. So we will develop and improve a new risk management system and a disaster prevention system to preserve and create the city environment where people feel easy and sound in their life. 保护环境初三英语作文（三）

Pollution has been a serious problem for a certain time around the world. There are many causes for it. Transportation is the main factor of pollution. When the waste gas from cars is released, the air is polluted. People breathing in the polluted air can develop respiratory disease. Another factor is that people throw their garbage everywhere. All kinds of garbage not only spoil the splendid environment, but also cause environmental pollution. Whats more, industrial pollution also deserves our attention. Wastewater from factories is poured into rivers and this causes water pollution. As a consequence, the greenhouse effect becomes a problem which needs our immediate caution and how to solve is urgent all over the world. At present, some measures have been taken to prevernt.

For example, people classify the garbage and some is recycled after being collected. People are also encouraged to use paper products instead of plastic products because we know that our living condition will be worse if we keep ignoring this problem. And I believe we can prevent pollution if everyone makes the efforts.

虫类，数不甚数;但“钱虫”你见过吗? insects, the number is not even; but have you seen "money and insects"?

有一幅这样的画：一个人，在砍伐树木，一只啄木鸟停在他头上，一边啄他的脑袋，一边说：“这段木头里一定有虫。”是啊，的确有一条虫，一条害人害己，害地球的“钱虫”一条可以慢慢地把地球侵蚀的虫!

而这就是这幅画让我更加明白了一个道理，一个我们全人类都要知道的道理：爱护地球，保护地球。就是这么一个小小的口号，我们做到了吗?

伐一棵木看着没什么大碍，但是全世界每人砍一棵树，60亿的树木顿时消失，你们想过这个危害有多大吗?洪水，沙尘暴，土地沙漠化，山体滑坡，泥石流，等各种自然灾难，会爆发，二氧化碳会得不到净化，臭氧层会日益变薄，人类将面临灭绝的灾难。

如果我们不加节制地砍伐树木，污染土地，那么，离人类灭绝的时期就指日可待了。如果我们再肆意乱扔白色垃圾，地球将陷入空气危机，环境危机，食物危机，等一切危机。如果我们再向河流吐痰，大海吐痰，你们可以想象60亿人的痰汇成的痰海是多么“壮观”啊!

地球，原来是一个多么美丽的星球，是一个多么自然和谐的星球;可现在，被人类弄得乌烟瘴气，完全失去了以前朝气蓬勃的样子。我多么希望，大街上，不要有汽车啊，每天回家，看见汽车尾部排除的尾气让我头晕眼花，闻见那一个个刺鼻的气味让我丧失心情;我多么希望，每天上学放学都可以闻到，大自然的芬芳清香;我多么希望，当我为作业而烦心，为很多事烦心的时候，可以看到一片翠绿的景象······竭泽而渔，说的就是我们现在的伐木工人等一些人，永远只会在乎眼前，不会去想着将来所会发生的事。一旦以后发生了后果严重的事情，才知道，自己做错了事情。

我们应该大声地呼吁，大力地宣传：地球只有一个，不要让地球消失在茫茫宇宙中;地球只有一个，我们应该保护地球上的一切生物!

身边的环保，每天都在发生。 The environmental protection around you happen every day.

——题记

上高中了，一早上起来，比你起得更早的是谁?实在打扫的清洁工们。他们也是辛勤地“蜜蜂”，与老师的有异曲同工之处，他们无论是烈日炎炎还是寒风徐徐都是在最早的时候进行，他们是我们世界的第一层环保，为我们把一天留下的垃圾收拾掉。

街道旁，你是不是会看见“路边的野花，你不要踩”类似如此的告示牌，这就是环保，环保其实就是少扔一张纸，少踩一棵草，就是如此简单，但就是这么简单的一件事情，又有几个人做得到呢，懒是造成环恶坏的问题。

康菲石油泄漏，五千平方公里，渤海早已成为渤油，这件事件先不说损伤，就拿环境保护来说，这些巨大的危害，造成的后果无法估量。

现在的灯红洒绿，现在的车水马龙，早已成换不回那原生态的大自然了。

我向往田园生活，乡村生活，小鸟唱起了圆润的歌，蝴蝶在那翩翩起舞，青蛙为我打起了小鼓，蝈蝈喂我弹起了吉他……

我爱乡村，那是因为它绿，是一个美丽的地方，乡村是一个寂静的地方，乡村是一个与世无争的地方，乡村是淳朴的地方，他与世无争，像一张白纸一样，没有一丝杂质，这就是最初的世界，而不是机器在高歌，汽车在伴奏，垃圾的天堂的城镇。

我也会乱丢垃圾，也无法知道这一后果的严重，当我知道的时候，早已为时过晚，森林的砍伐，水质的破坏，造就现在这一个千疮百孔的地球，我们应该反思，反思我们人类所作的一切。

春雨，夏阳，秋叶，冬枝，我们还能看见他们的原样多久，现在也早已变形。

我身为一个高中生，改以身作则，为国家作出贡献，尽量不乱丢垃圾，不随地吐痰，以后为了我们大家的家园——地球，共同努力，换我们后代一个清白的地球!

Animal is the friend of mankind, is an important part of the natural ecosystem. It is human precious naturalresources. Protect animals to maintain natural ecological balance has important significance.

But now many animals are facing the danger of extinction.With the development of society, pesticide used and serious pollution, city sewage .The wild animal living area is becoming increasingly narrow. Many of the animal is facing a food crisis currently . Whats more, in order to obtain wild animal of precious materials, humans are killing animals.

In order to maintain ecological balance, we should take some effective measures to protect  animals.We should develop pollution standards to reduce emission of toxic substances,  prevent the killing of some rare animals strictly.  We can also establish a national park as a wild animal protection area. The most important thing is to improve people s knowledge of animal care.

Let us join hands in creating a harmonious coexistence of human and animal beautiful homes!

同学们：如果草儿不再翠绿，如果大海不再湛蓝，如果你的眼睛渐渐的看不到光彩的颜色，那是因为地球母亲失去了她美丽的“外衣”——臭氧层！犹如轻纱笼罩着地球，臭氧层可以遮挡过多的紫外线，给地球上的生命带来勃勃生机。然而，由于人们过多的使用破坏臭氧层的物质，臭氧层被无情地撕扯出了几个破洞。

为了给地球缝补破损的“外衣”，全人类都在努力所以提高对保护臭氧层活动的认识，从全球利益和国家利益高度认识到保护臭氧层的重要性，积极支持淘汰消耗臭氧层物质的工作是必要的。地球是我们共同的家园，臭氧层是保护我们共同家园的屏障，让我们一起来保护臭氧层，为地球母亲撑起一把保护伞，给地球一片绿色，还人类一片安宁吧！

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.

我的名字叫做地球，我是一个晶莹的球体，蓝色和白色相互交错着，周围裹着一层薄薄的水蓝色“纱衣。”

同茫茫宇宙相比，我是渺小的。我是一个半径只有六千三百多千米的星球。在群星璀璨的宇宙中，就想一叶扁舟似的。哎，我只有这么大，不会再长大。

我所拥有的自然资源也是有限的。比如说矿物资源，它不是上帝的恩赐，而是经过了几百万年，甚至几亿年的地质变化才形成的。我是无私的，也是伟大的，我就像你们的母亲一样为你们慷慨地提供矿产资源。但是，如果不加节制地开采，必将加速我身上的矿产资源的枯竭。

你们生活所需要的水资源、电资源、大气资源等等，本来可以不断地再生，长期给你们做贡献的。可是，因为你们的自私，随意地破坏我身上的自然资源，不顾后果地滥用化学品，不但使我的20%的绿色皮肤慢慢地变成了黄色，还使我最骄傲的蓝色皮肤渐渐变为灰色，所以导致自然资源不能再生。你们在我身上索取了多少，我都会回报你们的。像5月份的汶川大地震，如果你们懂得合理地利用我身上的资源，弄的我非常痒，我也不会打一个大喷嚏，使汶川的房子被吹倒，人都被砸死了。我…也不是故意的呀！哎，不说了。

现在科学家已经证明，在以我为中心的40万亿千米的范围内，没有再适合你们居住的第二个星球了。你们不能指望破坏了我之后，再去破坏我别的同伴。

如果我被破坏了，你们别无去处。如果我身上的资源枯竭了，你们就很难得到补充。如果你们适可而止，不再我身上做实验，而且恢复我的本来面目，我会努力的保护你们，更好地造福于你们的子孙后代。要记住：保护地球，人人有责！
