现在,科技越来越发达,这是一件可喜的事,但这也是我们的一大损失!为什么?因为人们没有好好保护环境啊!你看,树木慢慢地枯萎了,小鸟不再唱歌,蝴蝶不再跳舞,有的只是那可恶的细菌和浓浓的黑烟,以前的鸟语花香一下子全消失了!人们不但没有保护的意识,还火上加油,不是乱扔垃圾,就是随地吐痰,虽然只是一点点垃圾,一口小小的痰,但是,日积月累,就造成了空气污染,让蚊虫胡作非为,你们觉得好吗？

现在,保护地球的臭气层已经穿了一个洞,我相信你们都知道,这是因为汽车里的冷气飞出来后,不能蒸发,所以飞上了天空,产生化学作用,伤害了臭气层.还让紫外线射进地球,伤害人们的皮肤,晒多了还会导致有生命危险,你看,到头来受苦的还是我们自己.还有世界上最后一个没有被污染的地方-南极,最近,科学家们发现,企鹅身上有一种有毒物质,这是怎么会事呢?原来,是遥远的北半球被污染的空气飘到了南极,受到冷气后结成了冰,鱼和虾吸取之后再被企鹅吃进肚子里,所以企鹅体内才会有有毒物质的.这证明,南极也被污染了！

地球妈妈把她的一切都给了我们,她总是倾其所有,而我们却不懂得珍惜,还执迷不悟,不断地破坏环境.现在,我们的家园已被完全污染了,地球妈妈不但伤心,而我们也正陷在水深火热之中!聪明,伟大的人类,醒醒吧!让我们一起保护环境,保护我们的家园!

Nowadays, unsafe foods can be found, now and then, in the market, which has aroused a lot of public attention. It is reported that these foodstuff ranges from substandard milk powder, dyed steamed buns to pork with lean meat powder.

Fake commodities are harmful in many ways. To begin with, it is a waste of resource, especially in our country. Second, it has bad effect on the reputation of the real manufacturers and brings about moral Crisis.

Above all, all that matters is food. Peoples health and lives are severely threatened if someone buys some unsafe foodstuff.

Measures should be taken to deal with the problem. On the one hand, strict laws should be passed to punish the producers and the sellers. On the other hand, consumers should be told to distinguish the genuine goods from the false ones. At the same time, the government should strengthen the supervision of all aspects of food.

I firmly believe this problem will be solved in the near future.

如今,可以发现不安全的食品,,然后,在市场上,这已经引起了大量的公众注意力。据报道,这些食品范围不合格包括奶粉、染色馒头和瘦肉精猪肉。

假冒伪劣商品在许多方面是有害的。首先,它是浪费资源,尤其是在我们的国家。第二,它也有坏影响真正的制造商的声誉和带来的道德危机。

首先,最重要的是食物。人们的健康和生命都严重威胁，如果有人买一些不安全的食品。

应采取措施处理这个问题。一方面,应该通过严格的法律来惩罚生产者和销售者。另一方面,消费者应该被告知要区分真正的商品和假的。与此同时,政府应该加强食品的各个方面的监督。

我坚信在不久的将来将会解决这个问题。

Dear Jim,

I’m very glad that you’ll come to visit China. You asked me about the weather in China. There are four seasons– spring, summer, autumn and winter. Summer is the hottest season of the year. It often rains. And winter is the coldest. Sometimes it snows, especially in the north of China. If you like snow, you can come to China at this time of year. But I think the best time to visit China is in spring or autumn because it is neither too hot nor too cold. It is very pleasant to visit many places of interest in China, such as the Great Wall, the West Lake, Mount Yellow and so on. I believe you will enjoy yourself in China. I can’t wait to see you.

Best wishes!

Yours truly,

John

深圳市环保局的各位领导:

在当今世界飞速发展之际，环境污染以成为了全世界以及全深圳市共同面临的重点问题。深圳作为一座国际花园城市，却出现了另一番不协调的景象：深圳河水变得混浊、发臭；汽车尾气弥漫着整个城市的上空，变的灰蒙蒙的；公园里随处可见果皮垃圾；到处都有牛皮癣小广告……。善待城市环境，对于每一个家庭都非常重要，我们不能为了一时的痛快给自己带来灾难。为了让天更蓝，让水更清，让我们的深圳更加清洁美丽，所以，我建议大家：一、爱护环境，保护水资源，节约的用水，不要让眼泪成为最后一滴水。

二、垃圾分类，废物利用，保护再生资源，要有限的资源，无限的循环。

三、少用一次性物品与筷子，多多种树，让树更好的美化深圳。

四、尽量乘坐公共交通工具，降低噪音，减少汽车尾气污染。

我们只有一条深圳河，她如果被污染了就不再清澈；我们只有一个深圳，她如果被破坏了就不再美丽……。保护环境取决于我们每个人的行动，取决于你、我、他。为了绿色，为了这美丽的深圳，让我们行动起来，从我做起奉献出自己的一份力量吧！

Save the Wild Animals

Many wild animals are facing the danger of extinction, because the environment that they are living in has changed greatly. For example, with the developmet of cities, the using of insecticide and serious pollution, their living areas have become narrowcr and narrower. Many of the wild animals, now are confronted with food crisis. At the same time, man is killing off species just for getting their fur, skin, horns, teeth and meat.

In order to protect our resources of ecology, people should realize that the loss of any species is at least the loss of source of knowledge and a source of natural beauty. There fore, measures of the following should be taken: pollution standards are made to keepdown poisons; killing off certain rare species is prohibited; national parks should be set up as wild life, reserves.

Only if we human beings take some drastic measures can wild animals be preserved.

保护野生动物

许多野生动物正面临绝种的危险，因为它们生活的环境发生了极大的变化。譬 如，随着城市的发展，杀虫剂的使用和严重的污染，野生动物的生活区域变得越来越狭小。许多野生动物目前正面临着食物方面的危机。同时，为了获取野生动物的毛、皮、角、牙齿和肉，人类正在屠杀野生动物。

为了保护生态资源，人们应当意识到任何物种的缺失，至少意味着知识资源和自然美的缺失。因此，应采取以下措施：制订污染标准以降低有毒物质;严禁杀害某些稀有物种;应建立国家公园作为野生动植物保护区。

我们只有采取一些有力措施，才能保护野生动物。

The Spring Festival is very important to Chinese people. In the past，people could not often have meat，rice or other delicious food. They could only eat these during the Spring festival. So every year they hoped that the Spring Festival would come soon. Now， although people‘s life is much better，and we can eat the delicious foods everyday. People still like the festival. Because most people can have a long holiday，and we are free to go on a trip or visit our friends or have parties with our family. In the evenings，we can have a big meal in the restaurant or stay at home with family and watch the TV programs.

过年对中国人来说非常重要。在过去，人们往往没有肉，大米或其他美味的食物吃。他们通常只能在过年吃到这些。所以每年他们都希望过年可以快点来。现在，虽然人们的生活好多了，我和家人每天都可以吃美味的食物。人们仍然喜欢的过年。因为大多数人可以有一个很长的假期，我和家人可以自由地去旅行或拜访我和家人的朋友或与我和家人的家人聚会。晚上，我和家人可以在餐厅大吃一顿，或与家人留在家里看电视节目。

I like the Spring Festival very much. How wonderful the Spring Festival is！

我非常喜欢过年。过年是多么的美妙啊！

夜晚，明亮的路灯、大楼上的装饰灯、汽车灯光、广告牌的灯光以及公共设施的灯光等都会造成光污染。白天，我们同样会受到光污染的侵扰，如：楼房上的玻璃和大理石等做成的外立面，对日光的反射也会影响我们的生活。你可能会有疑问，那么就请带着疑问看看光污染带给我们的危害吧。

不适当的照明会让我们感到烦躁，我们的生物钟一直按照日夜循环的自然规律在运转，不论是新陈代谢、心率还是体温，都和生物钟息息相关。在它的指挥下，我们在白天精神百倍，而到了晚上就要睡觉，所有器官的活动同时也会减速休息。试想，本来是晚上睡觉的时间，可是由于过度光照的影响，生物钟发生错乱，误以为是白天，它的活动就不正常，那么我们的身体肯定会受到影响，如心情烦躁、睡眠障碍、头疼等。

不适当的照明致使天文台被迫搬家。日本东京的天文台自1878年建成以来，曾多次搬迁，原因就是大型望远镜在光污染的影响下能观测到的天体已经寥寥无几了。现在，只有在没有光污染的偏远山区，才能看到满天的星星。

不适当的照明也是全球气候变暖的罪魁之一，全世界每年照明的耗电量在两万亿度以上，如果燃煤生产这些电会排放20亿吨的二氧化碳和6000万吨的二氧化硫，而全球变暖主要是二氧化碳造成的。除此之外，照明设备还会释放很多热量，这也是城市温度不断上升的一个重要原因。

光污染造成的负面影响如此严重，该如何补救呢？

首先，每个人都要有减少光污染的意识，积极参加环保活动。

另外，要设计更合理的照明工具，改善照明条件。还可以增加遮光罩，使需要光照的地方很明亮，又不会给周围环境造成光污染。减少使用玻璃、大理石等反光材料作为建筑物的外立面。

减少光污染刻不容缓，让我们行动起来吧！

Air pollution is one of the major problems of the modern world. A great deal of energy is needed to run the factories of modern industrial nations. Automobile, trains, planes and busses need energy, too. Nearly all of this energy is produced by burning fuels. The burning produces wastes, some of which remain in the air, causing air pollution. Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities. They are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are being modernized to give off less polluted material. Also, engineers try to design and locate new power plants to do minimum damage to the environment. However, it may be that we still have a long way to go before we have a "clean" world. Nearly all of the countries are trying hard to prevent and control air pollution. There indeed seems to be no end to tasks that environmentalists will be required to do. People will continually find new ways to control pollution.

I am a student. And I know every student need to go to school for almost 20 years, if a student go to university or college after high school, he or she will stay in school for 5 more years. So precious is time that we cannot afford to waste it. But there is a question. Whats the point of doing all this? Whats the purpose of study?

In my point of view, nothing is more importance than to receive education. The magic of education can make person intelligence, smart, and reasonable. Physics and chemistry can help you to understand the world. Math can help you to be smart and train your brain. Art, IT, and planning can help you to learn some important skill in tomorrows world. Language can help you to community with others.

So the reason why we are learn in school for such a long time is because you will understand that no subject you are taking is a waste of your time.

Math, physics, chemistry, biology, and earth science are researched by all human in the past. On the other word, it is human culture we are learning. But the most important thing is these results were discovered by the people in the past. Right now, we just have to understand it. How simple is that?

In all, learning things from school is not only for you can survive in the society in the future, but also a study of a human race.

Nowadays, the environmental protection is becoming one of the most important issues in the world. Being one of the members of our society, what shall we do to protect the environment

First, stop using plastic bags, boxes and bottles. Stores should be required to use the bags, boxes and bottles which are made from paper. Secondly, more and more trees and flowers should be planted to keep our surrounding clean. People must be required to plant plants around their houses and work places.

Finally, we must control the pollution by law, according to which, polluted water and air exhausted from factories should be forbidden.

These are some of the measures that we can take to protect our environment and they are not hard tasks for us. Remember, the earth is the only planet we could live at present.

Since the first day, BNBM has paid more attention to protect the environment as its social responsibility, by developing green building materials, producing green products and creating green enterprise. According to the spirit of "From the nature, for the nature and return to the mature", BNBM has tried its best in developing new technology and improving equipment to reduce the pollution.

良好的环境能让人心情舒畅。改善环境，意味着修饰我们的生活。 改善我们的环境，我们应该做些什么呢?

我们应该种更多的树。我们应该防止这些工厂废水浇入河流，湖泊，田野。每当我们看到地上有垃圾，我们应该拿起它，并把它扔进一个垃圾箱。

不要在公共场所随地吐痰。不要在公共墙壁乱画。让我们的地球保持干净和整洁是我们的职责。

Pollution is harmful to human beings. Polluted water causes many kinds of diseases such as diarrhea, enteritis, etc. And sometimes these diseases even take man’s life. Dirty air or air-borne garbage causes stinging eyes and running nose. Pollutants are destructive. They cause runs in nylon stockings and crack rubber tires and they eat away at stone and rust iron.

Measures have been taken to control pollution. In recent years, legislative steps have been introduced to control pollution. Rivers are being cleaned. Air is purified, and pollutants are being trapped before they are poured out of chimneys.

However, pollution problems have not been completely solved. Pesticides are widely used almost everywhere. They pollute soil, water and food. They have the power to make our streams fishless and our gardens and woodlands silent and birdless. Some factories are still using air as a dumping place for wastes. Some lakes are still dirty. Quite a few chimneys are still pouring smoke into air and noise pollution remains serious.

now, the degree of urbanization has been deepening and we enjoy the convenience brought by urbanization. how does everybody know how the cities began? long time ago, the world had only a few thousand people. these people moved from place to place, hunting animals for food. no one knows how or when these people learned about growing food. but when they did, their lives changed greatly. one thing is certain that they gathered in the rich place or near water. in that age, water and climate are the most important to lives. it is the rich water and comfortable climate that gathered people from different places. they began to live near one another, so that the first village grew. many people came to work in the villages. then the villages became bigger and bigger.when machines were invented, life in the villages changed again. factories were built. there were a growing number of people living near factories. because of the increasing people, more and more buildings were built. and then cities were built.

今天，我来到花圃，准备观察被污染的事物。

我找啊找。这时，一股臭味迎面扑来。我一看，哇，一条臭水沟，水黑呼呼的，漂着一层油。上面有可乐罐、香蕉皮、木棍……我想：我们人类真是太不会保护环境了。这种现象真不好。再这样下去，地球就完了。

我走啊走，发现呼吸有一点不舒服，我想：这里一定没人管过，我看风汽车尾部有一个圆筒，正排着一些黑色的气体，因该是废气，有毒的，对身体一点也不好。

这时，我突然发现有一些草枯萎了，一定是土壤被污染了。小草吸收后，就中途死亡了。我们真是太不应该了，把自然界的生物污染了。

让我们不要再这样下去了，好好保护环境吧！
