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。

最近我发现我们的学校发生了一些不好的现象。

平时十分整洁干净的校园，最近却变的有些脏兮兮的，一些角落里或者是走廊里，都能看到同学们用来装事物的塑料袋，还有一些水果皮、碎纸屑和吃完小零食以后扔掉的包装袋。我们学校是每个班都有一定的卫生打扫的负责区域的，每天每班都会安排学生打扫，这些垃圾肯定都是在同学打扫完卫生之后，又有人丢下的，我觉得这些同学的素质真的很低，都不知道珍惜别人的劳动成果，不知道保护校园的环境。

同学们，不以善小而不为，不以恶小而为之，大家携起手来，共同保护我们的校园环境吧!

A new language opens up a whole new culture. A foreign language gives us access to another culture, and our lives take on a new dimension. The great German poet, Johann Wolfgang von Goethe, said in 1827: "Whoever is not acquainted with foreign languages knows nothing of his own." Seen like that, learning a language is almost comparable to a journey of discovery - and if we remember the great explorers and the 18th century gentlemans grand tour, you might almost call it a British invention.

我是太阳妈妈的孩子，我的名字叫地球。我以前生活的很快乐：早上一醒来，小雨就“哗啦啦”地给我洗澡;人们在我身上种了很多花草树木，把我打扮得漂漂亮亮的，然后，干干净净的我就围着太阳妈妈转来转去，让太阳妈妈看看我的新裙子。下午，孩子们放学了，就和我一起写作业，一起和我玩。晚上，人们也把我打扮的很漂亮，他们给我身上安上路灯，把我打扮的金灿灿的……太阳妈妈说：“人类还真好，不仅把你打扮的很漂亮，还和你一起玩，你真是太有福气，太幸运了!”

可是现在，人类也不像太阳妈妈说的那么好了。他们在我身上乱扔垃圾，把我搞得浑身脏兮兮的，人类的“车”还爱排放尾气，雨下下来的全是脏水，把我越洗越脏;人们还爱乱砍伐树木花草，破坏路灯，把他们给我的衣服也搞得的烂烂的，脏脏的……太阳妈妈劝我说：“你还是摆脱那些人类吧!”可是好心的我又不忍心丢下他们。因为这件事让我每天吃不好饭，睡不好觉，所以，我就生病了，经常发洪水、地震……还有人说2012年可能是我的末日。人们在这些灾难中，意识到了这都是他们破坏我而造成的，于是他们又开始关心我，爱护我了!我相信以后的日子里，我一定会变得更加美丽、漂亮的!

Today, as the development of the technology, people live a much better life than before, the average wage is promoted highly. The economy develops at the cost of polluting the environment, we can see the pollution everywhere, like the river water is dirty, the situation is so serious that we must take some action to control the environmental pollution. First, we should not throw away the rubbish, whenever we have rubbish at hand, we should keep the habit to throw it into the dustbin, sometimes the garbage can be recycled. Second, the government should make some measure to punish the industry which is not deal with the pollution well. With the government’s intervention, the businessmen will pay special attention to the pollution and dare not to ignore it. Protecting the environment needs everyone’s effort, to ourselves and our offspring’s health, we must take action to protect the environment.

Last summer holiday, I went to Hainan with my family.The weather was terrfifc! The sky was bule more than I could describe, the sea was blue and bright more than I could believe. Walking by the sea is just like being in the oil painting! We sailed to an island called Xidao. I swam there.Swimming is the sea is quite different from that in a pool. Because the depth is various all the time. Maybe the water cant afford you this minute, and then it will flow over your head! Besdieds the swimming, we also had a good meal there. We had a nice seafood dish. I forgot the name of that conch,but I bought back the shell. If you want to have a look, you may ask me. Or, we may go to Hainan together, for I am always hoping to come to that place again. I really like that place, a place of bule and brightness.

How 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 shouldn’t cut them down . We should stop factories from pouring waste water into the river and waste gas into the air.

Whenever we see litter on the ground , we should pick it up and throw it into dusbins. Never spit in public. Don’t draw on public walls. It’s our duty to protect the environment.

I am not supportive of the idea that either takes priority. It is necessary and absolutely possible that economic development and environmental protection co-exist, in the sense that both of them are indispensable factors for the prosperity of society.

Economic development is seemingly more important, due to the fact that it creates enormous job opportunities, improves living conditions and increases government revenues. Yet, the above goals can only really be reached on condition that the environment is well protected. And, interesting, it is the economic development per se that provides the money and personnel resources required for the protection of the environment. A well-preserved environment is the groundwork for the economy and in a way promotes economic growth. A fast-development and well-functioning economy calls for a good environment, which offers essential resources, e.g. wood, coal, water, and so on. Once the environment deteriorates, the production process is likely to be disturbed or even halted. What is worse, natural disaster that comes with the worsening environmental conditions might even paralyze the whole economy and pose a severe threat to human life. The pursuit of short-term economic profit is the destruction of our home and that of our posterity.

So economic development and environmental protection are equally important. In this case, we are actually working on an environment-friendly economy.

Recently, it is very popular to live a low-carbon life.Living a low-carbon life is ofgreat importance to every one. First of all, it can protect the environment to a great extent. Second, it can save the limited natural resources and energy, and will leave a better world for our offspring.Third, it is a healthy lifestyle and will help mould a harmonious social atmosphere.

Therefore, how to create a low-carbon life is necessary for us to consider. To begin with, we should save the energy, such as the electricity, water and domestic gas. Second, when we go out we can walk or ride a bike instead of by car. Third, we should not use the plastic bags which are hard to break down. If so, we can live a low-carbon life and gain the happiness of it.

how to solve the energy shortage（如何解决能源短缺问题）

energy shortage is a very serious problem in the world. many people worry that energy resources on the earth will be exhausted if we use them in an unchecked way. this, most people agree, will cause serious problems and even crisis and jeopardize the survival of mankind .

on the one hand, most people agree that the problem can be solved in one way or another. one is to conserve and save our energy. energy refers not only to coal, oil, or natural gases but also to goods, land and water, etc. most countries have realized the wastefulness in their using of energy. they are trying to conserve energy. for example, some countries have a daylight saving system to use less electricity for lighting. some cities have enforced water savers at public such as restrooms and bars. some have enforced serious penalties on overuse of electricity, water, and farming land. by these means, people hope the drain on energy resources could be slowed down.

however, conservation alone cannot solve the problem. another way, perhaps the best i think,, is to develop new energy resources. obviously, no matter how hard we try to save energy resources and how abundant they are, we will use them up sooner or later. i think there are many energy resources that we can develop and utilize. we don’t have to depend only on the current conventional energy resources. there are many other energy resources that we can develop such as nuclear power, waterpower and solar power. these resources, if developed, can completely replace the conventional energy and thus solve the problem of energy shortage.

星期天，我和爸爸妈妈去游玩周庄和同里古镇。 一大早，我们就赶到天宁寺附近的常州旅游集散中心，坐上了旅游车。车上一共有45位游客。 我们在车上坐了两个小时终于到达了周庄。一进去，导游带我们走过了富安桥和双桥，还参观了张厅、沈厅和南湖秋月园等景点。最后，导游说：“自由活动。”我们就全解散了。我和爸爸妈妈去了怪楼，拍了各种各样奇怪的照片。有倒着的人、鸟人、虚幻空间、变身小屋、横廊、小人屋、长腿人和幻听视觉。其中我最喜欢虚幻空间，因为拍出来的照片就和真的一样。其中有一张就像坐在蟒蛇的嘴巴里，妈妈在边上拉着我，就想把我救出来一样。 自由活动完了后，我们大家又集合了。

我的家乡是一个物产丰富，花草茂盛的地方——山东.

我经常和邻居家的小弟弟去小溪边玩，有一次，我骑着自行车带着小弟弟去小溪边玩，这里的溪水清澈见底，花草也长的非常茂盛，溪里的贝壳好看极了，有黄色的，有绿色的，有黄色的，怎么数也数不清，我和小弟弟经常在这里打水仗。

可是，在我六岁时，我又一次骑着自行车，带着小弟弟去小溪边玩时，我看到了家乡的小溪发生了很大的变化：溪水变得又黑又臭;贝壳看不到了;小鱼都死了，浮在水面上;又有一些垃圾在水面上漂浮着。看到这场景后，我和小弟弟都惊呆了。

我决定在每年的春天，我都和爸爸妈妈回家乡种几棵树，和家乡的小朋友们共同发起“养一盆花，栽一棵树，爱护每一片草地，不乱丢垃圾”以及让我们的爸爸妈妈“放下方便袋，拿起菜篮子”的倡议。

虽然，我们现在做的只不过是一些鸡毛蒜皮的小事，但是我相信，只要我们人人都有保护环境的责任心，那么我们就会看到一个干净又美丽的世界!

白色污染White Pollution

With the remarkable improvement of people’s living standard, people tend to buy more goods. As a result, a plenty of plastic bags are threw around and caused white pollution. Not only does it do harm to the environment, but also give people the impression that the city is dirty. As we all known, plastic bags are non-biodegradable material and it will stay in the soil for a long time. What’s worse, the poison released from the plastic bags is harmful.

随着人民生活水平的显著提高，人们购买的商品越来越多。所以，到处都是塑料袋，造成白色污染。塑料袋不仅污染环境，也给人城市很脏的印象。众所周知，塑料袋是不可生物降解的材料，会长期留在土壤里面。更糟糕的是，从塑料袋中释放的有毒物质是有害的。

Being current generation of young people, we should take measures to control the use of plastic bags .We can substitute them with cloth bags or reuse them. And the government can make rules to avoid using them. If we do our best, the use of plastic bags can be reduced, thus the white pollution can be controlled.

作为当代年轻的一代，我们应该采取措施来控制塑料袋的使用。我们可以用布袋来替代塑料袋或者重复使用。政府也可以制定规定来避免使用塑料袋。如果我们努力做好，塑料袋的使用就可以减少了，从而白色污染也会得到控制。

Desert, rose water, cancer... With humans dont care for the environment, damage to the environment has a lot to do. Like a clear brook became black stink; Dense woods turned into bare land; A variety of animals also slowly become extinct. The earth mother is sick!

Fish said to the bird, "you know what? This small pools has been dead for more than a dozen fish!" , the bird said, "yeah! Dont fresh the air here, all want to put my stuffy dead!" .

Trees in the forest, said: "life now is very dangerous, or by some naughty children bend the branches up; or that has been cut off. In short is having a hard time."

Reptiles are also said: "ah! Our days sad ah, also is afraid of people eat, or in the zoo, or be in the circus show. Its really a terrible world!"

We these uncivilized habits will not only bad for plants, animals, also not be good to oneself. Some people just because of air pollution, some people get sick because of water pollution, and mother born child is abnormal, there are some men smoking lit trees, also caused the fire, forest were destroyed, ecological destruction. In this way, the earth slowly turned into a garbage dump in the universe.

The earth is our survival homeland, destroy the earths environment, is destroying our human oneself. So, we human beings should protect the environment. Protect the environment, our children to start small, put the rubbish into the dustbin, and sent him to the correct boxes. Hope everyone is less by car and more riding a bicycle, advocate green travel. Save water, reduce waste. Let the earth mothers illness get better gradually. Let the sky bluer, the water cleaner, the grass is greener and more colourful flower. Become the most beautiful and good earth!

沙漠、涨水、癌症……都是跟人类不爱护环境，破坏环境有很大的关系。像清澈的小河变成了乌黑发臭;茂密的树林变成了裸露的土地;一种种动物也慢慢灭绝了。地球妈妈生病了!

小鱼对小鸟说：“你知道吗?我们这个小水池已经死了十几条鱼了!”，小鸟说”对呀!这里的空气一点儿也不清新，都要把我闷死了!”。

树木们在森林里谈到：“现在的生活很危险，要不就是被一些顽皮的孩子把树枝弄弯;要不就是被人们砍伐掉。总之就是不好过。”

爬行动物们也说：“哎!我们的日子也难过呀，就怕被人们吃了，或被关进动物园里，或被放进马戏团里表演节目。这真是一个可怕的世界呀!”

我们这些不文明习惯不光会对植物、动物不好，对自己也没什么好处。有些人就是因为空气污染而死亡的，有些人因为水污染而得病，还有的妈妈生下来的孩子就是畸形的，还有一些男人吸烟把树木点燃，还引发大火，森林被烧毁、生态被破坏。就这样，地球慢慢变成了宇宙中的垃圾堆。

地球是我们生存的家园，破坏地球环境，就是破坏我们人类自己。所以，我们人类要保护环境。保护环境，我们小孩要从小事做起，把垃圾丢到垃圾箱里，还要把他送到正确的箱子里。希望每个人都少坐汽车，多骑自行车，倡导绿色出行。节约用水，减少浪费。让地球妈妈的病渐渐好起来。让天更蓝、水更清、草更绿、花更艳。变成最美好的地球!

水里的小鱼也慢慢多了，森林里的树木也旺盛起来了，动物们也有一个幸福的家园了!这应该才是我们美丽的家园，把原来的坏习惯改了，保护环境。

Will Tourism Bring Harm to the Environment?

Tourism has developed by leaps and bounds in the past decades in the whole world. Therefore, the issue of whether the tourism will bring harm to the environment is becoming a matter of concern. As for me, I hold that the tourism does more harm than good to the world.

In the first place, the more places we travel to , the more pressure will be added to the environment. Take Dunhuang as an example, the greatest scourge these days comes from the tourists who swarm here by the busload , bring destructive amounts of carbon dioxide and moisture into the caves along with their eagerness for a glimpse of ages past .

Secondly, It has become fashionable for travelers to drive a private car to the place they want to . In this case ,a large number of cars are mushroomed in the road and it cause twice as much as air pollution .At this speed ,we may live in a world which is full of dirty air instead of fresh air.

In sum , although tourism is playing an indispensable role in the society , I still believe that we`d better try to limit its speed according to the harm that brings to the environment.
