公园社区开展世界环境日宣传

Some people think that human needs for farmland, housing, and industry are more important than saving land for endangered animals. Do you agree or disagree with this point of view? Why or why not? Use specific reasons and examples to support your answer.

In the past, there have been many endangered animals. Now they are extinct. Does it matter? Has our environment been affected by their absence? Has the quality of our own life been changed? The answer to these questions is "Yes." It does matter if we destroy an endangered species habitat to develop more farmland, housing or industrial parks. There is a delicate balance of nature. If one small part is removed, it will affect all the other parts. For example, if certain trees are cut down, bats will have no place to roost. If they cannot roost, they cannot breed. If there are no bats, there will be no animal, or bird to eat certain insects that plague our crops.Our environment has been affected by the absence of certain animals. Certain flowers are pollinated by butterflies which migrate from Canada to Mexico. Some of the breeding grounds of these butterflies were destroyed. Now these flowers are disappearing from certain areas. We will no longer be able to enjoy their beauty.The quality of our life has been changed. America used to be covered with giant trees. Now we have to visit them in one small park. Rainforests around the world are being cut down to make room for humans. We will never be able to see or study this fragile ecosystem.I would encourage us humans to look for other alternatives for our farmlands, housing, and industries. We have alternatives; the animals do not.

Children’s education has been concerned by the public all the time. As they

are the future and will decide a country’s destiny, so the environment matters

so much to them. Most parents expect the school can provide the children a good

learning environment and ignore the importance of home education.

School provides the children a direct stage to receive education. In the

school, the teachers pass knowledge and educate them the right value. The

children know their task and as everybody around them focus the attention on

study, so they are affected by each other and have the strong desire to

learn.

Home education is easy to be ignored by most parents, they think it is the

teachers’ duty to educate children. Actually, most criminal teenagers have

family issues. Parents haven’t set good example for the kids. Sometimes they are

even the trouble makers. Without love, teenagers won’t grow up as the strong

people.

Both school and family environment are important for the children, and they

need to be nurtured with the good examples and learn knowledge.

environment

Plant human cells, if it damaged, destroyed nature organizations, to the eradication of mankind. Therefore, the environment must be linked with social ethics, character education and practice acts as an important elent of it. Everyone must fulfil its responsibilities and obligations to protect the environment.

【参考译文】

人与环境是和谐相处的,我们生存在地球上,人是自然之子,而不能仅把人看作自然的征服者,大家都知道,人类只有一个地球,地球上的山山水水、动物。植物是人类的细胞,如果我们把它损坏了,破坏了大自然的组织,等于消灭人类。因此,环境要与社会公德联系起来,与实践行为作为人格教育的一项重要内容来抓。每个人都要履行保护环境的责任和义务。

Dear Sir or Madame

Im very glad to be invited to the English summer camp.

I prefer to go in July because Ill have to prepare myself for the new school term in August. It seems all the activities you offer are attractive and meaningful. But Id like to attend the English lectures from which I can get more information on British and American culture. With the coming of the 2008 Beijing Olympic Games more and more foreigners are eager to know about China. So I hope to teach foreigners Chinese and spread Chinese culture.

Its been a dream for me to visit Beijing. Could you organize a tour around the city during the camp?

Thank you very much.

reation directors help plan the party, but the young people themselves take charge of the entertainment and the decorations — a necessary part of halloween. dried corn stalks, pumpkin faces, and piles of apples create the harvest atmosphere; and cutouts of witches on their brooms, goblins, ghosts and black cats symbolize the witchcraft aspect of the holiday. the freshments — apple cider, popcorn and pumpkin pie, and witches made of spicy ginger cookies — also carry out both themes.

there is an occasional adult halloween dance in a bright orange and black setting, with paper-made black cats, witches and grinning skeletons floating above the dance floor. but halloween has become mainly a young people‘s holiday — and the younger the child the more exciting he finds it.

万圣节前夜

10月31日，当一轮满月从空中升起的时候，小妖精、妖魔鬼怪、恐怖的巫婆、小捣蛋鬼——孩子们把小脸蛋藏在奇形怪状的面具后——会突然出现在朋友及邻居面前，并威吓着说：“不给糖，要倒霉。”

万圣节前夜，顾名思义，就是仅一个晚上的节日。在一年中的这一夜，孩子们的心灵充满了单纯的梦幻奇境。他们是节日的主人，而父母或其他大人只能起陪衬作用。在老师和商人的鼓励下，在前一年欢度万圣节前夜的美好回忆的诱惑下，孩子们(3至11岁)几星期前便开始准备服装和节日装饰了。虽然家长往往都要帮助孩子们准备服装，但在节日那晚，他们一定要装出一副被突然出现的带面具的鬼怪吓着了的样子。那时，会有穿着黑色长袍、戴着尖尖高帽子的小巫婆出现，她们乘着神扫帚飞过屋顶，飞到临街邻居的屋顶上；还会有披着床单的鬼怪出现，他们边跑边露着帆布鞋和短袜子；还有那可怕的海盗，他们戴着绘有骸髅及交叉的大腿骨的三角帽。有的孩子手提用南瓜刻成的人面形灯笼，但每个孩子都手拿着袋子或联合国儿童基金会发的盒子，上面写着：“不给糖，要倒霉。”很快，这些袋子、盒子里便都装满了糖果。

十几岁的孩子玩那些恶作剧的游戏，有时使大人们相当为难。他们向过往的车辆扔鸡蛋或西红柿；往玻璃窗、汽车挡风玻璃上涂抹难以擦掉的蜡；把南瓜滚下长长的山路；搬走门廊里的家具；偷走垃圾箱盖；在篱笆上乱涂乱写，到处惹是生非；这样来消耗掉他们多余的精力。警察虽然警惕性很高，但也只能逮捕那些真正的犯罪者。在许多社区人们举办交际舞会或街区晚会，以分散那些搞恶作剧的年轻人的精力。会后由商业界为最佳服装颁发奖品。虽然文艺指导帮助策划晚会，但是年轻人都亲自负责组织活动和动手装饰，这些是万圣节前夜的必可不少的一部分。晒干的玉米秆、用南瓜雕刻成的人脸以及一堆堆的苹果，使晚会增加了丰收的气氛；用各种东西雕刻成的乘扫帚的巫婆、妖魔鬼怪和黑猫标志了节日的魔力。晚会上供应的新鲜食品——苹果酒、爆米花、南瓜馅饼以及制成巫婆形的辣姜饼——既增加了丰收的气氛，又标志了节日的魔力。

万圣节前夜偶尔也有成年人的舞会，舞台背景为鲜艳的橙色和黑色，舞场上还舞动着用纸做成的黑猫、巫婆及龇牙咧嘴的骷髅。尽管如此，万圣节前夜主要是孩子们的节日—一孩子越小，就越兴奋。关于万圣节英语优秀作文：万圣节前夜

[万圣节的活动英语作文

Many people believe that we have developed into a “throw-away society” which is filling with plastic bags and rubbish. What do you think?

Wind blows up bags higher and higher in the sky. It is a scary thought that some day the earth will turn into a huge garbage land. Wastes, if not treated properly, will make our life a living nightmare.

The environmental issue is getting worse almost every day in cities with very large population. As is often the case, city development outpaces environmental protection. People consume great amount of natural resources and produce wastes. To effectively address such problems, cities need to spend big money. In addition, they need to call to the attention of people to become more environmentally responsible.

Many people are becoming less responsible and easily influenced by bad behaviors. “Why should I care while others shouldn’t?” Such idea makes some people only concern with places where they live and work. Furthermore, people sometimes even purposely litter for revenge to other people.

Although media promotes environmental awareness, good people are often snubbed as posers who try to set up a superior image in real life. Consequently, they are intimated of receiving negative comments for doing the right thing. Wrong as it is, such phenomenon is widespread especially among youngsters and people with low income and little education.

However, our society is waging a campaign against environmental pollution. People learn the harms of un-degradable lunch boxes and other polluting wastes. Laws in many countries prohibit or limit excessive use of polluting bags. Companies are continually replacing the old materials with more environmental friendly and recyclable kinds. Scientists have developed more effective technologies in waste treatment. As time goes by, more and more people put high priority on the protection of environment for a healthier life.

To sum up, people produce huge amount of garbage and the environment is seriously polluted because of lack of financial resources, sense of responsibility, or efforts. But the world will not turn into a “throw away” society if people put in sufficient efforts to protect our environment.

How to protect the environment

Its very impont for us to protect the environment good environment can make people feel happy and fit.To improve the environment means to improve our life.we should plant more trees and flowers around us.we shouldnt cut them down.we should stop factories from pouring west water into river.Dont draw on public walls.After all,its our duty to protect the environment.We hope our world will become more and more beautiful.

Today the quality of our natural environment has become an important issue. The world population is rising so quickly that the world has become too crowded.

We are using up our natural resources and at the same time polluting our environment with dangerous chemicals. If we continue to do this, life on earth cannot survive.

Concerned people have made some progress in environmental protection. Governments of many countries have established laws to protect the air, forests and sea resources and to stop environmental pollution.

Still more measures should be taken to solve environmental problems. People should be further educated to recognize the importance of the problems, to use modern methods of birth control, to conserve our natural resources and recycle our products. We are sure that we can have a better and cleaner place in the future.

Although the world develops much faster and better，the resources on the earth get fewer and fewer.In order to protect them，something must be done。

Save water. Water is the source of life. No water，no life. So its very important for us to do so.Not only should we protect drinking water and stop polluting it，but also make full use of it。

Save electricity. It is crucial. We cant imagine what the life will be like without it.Everyone should do his best to save electricity. Dont forget to turn off lights or other electric machines when we finish working。

Save forests. They are useful .Please stop cutting them down and use recycled paper instead. Make our world a green one to live in。

Recycle useful rubbish. Plenty of rubbish can be recycled like cans，paper，bottles，and so on。

We can save resources in this way. I believe we can make the world a better place to live in。

尽管世界发展更快、更好,地球上的资源得到越来越少。为了保护他们,必须得做点什么。

要节约用水,水是生命之源。没有水,就没有生命。所以这对我们来说是非常重要的。我们不仅应该保护饮用水和停止污染,但也充分利用它。

节约用电。它是至关重要的。我们无法想象没有它的生活将是什么样子。每个人都应该尽力节约用电。别忘了关掉灯或其他电动机器当我们完成工作。

拯救森林。他们是有用的。请停止切割下来,转而使用再生纸。让我们的世界一个住在绿色。

回收有用的垃圾。大量的垃圾可以回收罐、纸、瓶子、等等。

以这种方式我们可以节省资源。我相信我们可以让世界变得更美好。

cars have created a lot of serious problems in our world. all the time, they are pumping huge amounts of waste gases into the atmosphere, causing disease and even death.

one possible solution is to design and develop clean cars and clean fuels. but it may take decades for the new models to completely replace the traditional ones.

another solution is to develop modern public transportation systems and restrict the use of private cars. if the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not drive private cars. on the whole, the elimination of air pollution needs the co-efforts from the government and the public. this problem will be solved only with the help of science and technology.

The earth is our common homeland, we will not be able to live without the earth, so we should protect our home, cant let those greedy people destroy the earth.

Due to the deforestation of people, from underground oil, coal, discharge of sewage, chemical plant, built the earth has been scarred, because the tree is his bones and muscles, underground oil is his blood, the coal is his insides, the earth must be very painful, very hate him sons and daughters, should treat him so, but people did a show of indifference, said: "the earth is not to provide us with resources, hearing this, I am very sympathetic to the earth, feel sad for the earth."

And better homes in my heart is like this: people living in wooden houses, the home use is very of environmental protection, the source of all is depend on the sun can, as long as the sun will have electricity, car is the solar energy, environmentally friendly, green city, the birds come here to live and work in peace and contentment, singing a happy song, people no longer deforestation, wont hurt the earth, all living a happy good life, also wont kill some innocent little animals, the earth saw it all, happy smile, his scar is finally good, again is a fresh world.

While people used to hurt the earth, but now most people realize his mistake, and the country will also from time to time to do a publicity, to remind people to protect the environment, to become a good citizen, if people correct mistakes, I think my homeland in my heart, can come true soon.

地球是我们共同的家园，没有了地球我们将无法生存，所以我们要保护我们的家园，不能让那些贪心的人破坏地球。

由于人们的乱砍乱伐、从地下抽油、挖煤、排放污水、建化工厂，地球已经伤痕累累，因为树木就是他的筋骨，地下油是他的血液，那煤就是他的五脏六腑呀，地球一定很痛，很恨他的儿女们，竟然这样对待他，可人们却一副无所谓的样子，说：“地球不就是给我们提供资源的吗，听了这话，我非常同情地球，为地球感到悲伤。”

而在我心中的美好家园是这样的：人们都住着木头房子，家里用的东西都是很环保的，一切都是靠太阳的源能，只要有太阳就会有电，车都是太阳能的，很环保，城市里绿树成荫，鸟儿们都来这安居乐业，唱着愉快的歌声，人们不再乱砍乱伐，不会再伤害地球，都过着幸福美好的生活，也不会再杀害一些无辜的小动物，当地球看到了这一切，高兴的笑了，他的伤痕终于好了，又是一个精神焕发的地球了。

虽然人们以前伤害了地球，但现在大部分人都认识到自己的错误了，而且全国也会时不时的做一做宣传，时刻提醒人们要保护环境，做一个好公民，如果人们都改正错误的话，我想我心中的美好家园，不久就能成真的了。

上个周末，我和我的家人一同前往美丽的西溪湿地游玩。

虽然那里的优美风景让我们入迷，但是我们也看到了令人震惊的一幕。

那天，我拉着家人的手走了那小巧的摇撸船。我小心翼翼地迈出一步，踏上了摇撸船，一开始还摇摇晃晃的，但坐稳后，船便慢慢地平静下来，摇船者划着桨，平静的水面顿时卷起波纹。可是船一开到开阔的水面，水质则非常糟糕，只见水面不再波光粼粼，而是浑浊的油污漂浮在水面，包装盒和塑料袋等其他垃圾随地可见，原本清澈的水变得浑浊不堪。这时的我想，水这么浑，一定是包装盒的油污流进了水中，所以才会这么脏吧!

在回去的路上，我自言自语地说：“如果所有人都爱护环境，保护河流，那每一处环境都会干净、美丽，每一条河流都会清澈见底!"

让我们一起做五水共治的宣传者和执行者，让我们一起爱护环境，共同守护我们的家园。

in the late 1960s， many people in north america turned their attention to environmental problems， and new steel-and-glass skyscrapers were widely criticized。 ecologists pointed out that a cluster of tall buildings in a city often overburdens public transportation and parking lot capacities。

skyscrapers are also lavish consumers， and wasters， of electric power。 in one recent year， the addition of 17 million square feet of skyscraper office space in new york city raised the peak daily demand for electricity by 120， 000 kilowatts-enough to supply the entire city of albany， new york， for a day。

glass-walled skyscrapers can be especially wasteful。 the heat loss (or gain)through a wall of half-inch plate glass is more than ten times that through a typical masonry wall filled with insulation board。 to lessen the strain on heating and air-conditioning equipment， builders of skyscrapers have begun to use double-glazed panels of glass， and reflective glasses coated with silver or gold mirror films that reduce glare as well as heat gain。 however， mirror-walled skyscrapers raise the temperature of the surrounding air and affect neighboring buildings。

skyscrapers put a severe strain on a citys sanitation facilities， too。 if fully occupied， the two world trade center towers in new york city would alone generate 2。25 million gallons of raw sewage each year-as much as a city the size of stanford， connecticut ， which has a population of more than 109， 000。

people often think that water will never be used up. there is plenty of water, such as rain, water from the rivers and wells. it seems as if water is always available around us and we never have to worry about water shortage.

in fact water is rather limited on the earth. with the rapid increase of population and fast development of industries, water is more needed than before. at the same time, a large amount of water has been polluted and wasted every day. some big cities in china are facing the problem of water shorage already. there, water supply is controlled and industry has been restrained.

法国政府1996年4月提出了一项与城市污染作斗争，将市民“呼吸对身体无害的空气”的权利放在神圣地位的方案。

在法国市区行驶的汽车与伦敦一样激起公愤，而首先站出来为汽车辩护的是商店和其他做生意的人，因为他们担心限制使用小汽车会使他们失去顾客。

当局是因为担心夏秋两季空气质量会下降而采取措施的。法国公众担心夏秋两季的空气污染比伦敦和罗马有过之而无不及，而且柴油车尾所已危及某些郊区的生存。政府提出的措施是规定市政委员会必须监测空气质量并向公众通报、制订净化空气的地区计划和目标、当预测到空气污染已达到不能忍受的程度时允许局部交通限制实行局部交通限制、重新研究“汽车在有25万以上人口的大都市的作用”。其中大多数将在1998年之前生效。

尽管议案与公众的期望相去甚远，但仍不失为法国的起步。多年来，法国在接受“绝色”问题上落后于许多北欧国家。回收利用业相对不发达，直到前不久，空气质量还没有被作为一个问题提出来。
