I read a piece of news recently. It says that in Japan marly businessmen ave selling fresh air to customers.and now it is becoming more and more popular. Why?——Fresh air is getting less and less in Japan, and so is it in the U. S. A.

In fact, environmental pollution is a very serious problem the whole world is facing.

it is mainly caused by the waste products released from artificial substances, industrial production and increased consumption of goods. Bedsides, the use of chemical substances in agriculture also causes environmental pollution. Look at the sky, you can see that dense smoke is being released from the high and big chimneys; those dirty and poisonous substances are flowing into the rivers that we use for drinking water and millions of tons of waste products are heaping around us.

How to change this condition?More and more countries are trying to work out some effective means to bring it under control, but no great success has been made.

篇1:动物保护者

全文共 472 字

+ 加入清单

我们每个人都有一个、两个、三个,甚至四五个理想。记得托尔斯泰曾经说过:理想是指路明灯。没有理想就没有坚定的方向;没有方向就没有生活。

为什么我要当动物保护者呢?第一:我对动物特别有同情心,比如一些流浪狗、流浪猫之类的流浪动物,我会趁爸爸妈妈离开的时候给它们一些食物吃,一开始它们会半信半疑,(因为它们常常被一些卖狗肉,参猫肉的,引诱,然后就……)于是我就走的远远的,在一个隐蔽的地方看着它们吃完了,我才离开。第二:我对动物特别了解,我几乎每天都看快乐宠物,里面会有些关于宠物资料。比如我家的小泰迪——阿酷,我可以看阿酷的身体动作来判断它想要干什么。

如果再过上20年,30年,我真的当上动物保护者,我一定会禁止人们掠杀猫、狗之类的流浪动物,探索出尼斯湖水怪的真正面目,研究出治愈狂犬病的药物,还有最重要的事情就是要保护好动物,禁止虐杀动物,随便给动物喂食……要保护好环境,只有这样动物才能生存下来,如果没有动物我们也无法生存的,比如说牛,帮助人类耕田。

虽然我还没有当上动物保护者,但我也算半个动物保护者了,但是我还是要呼吁大家保护动物,从自己做起。

Space environment is the survival of humans we activities, such as: air quality, construction site, and the noise made by cars, water quality is good or bad, the streets clean and beautiful city, and so on belong to the environment. Now every day in newspapers and on television speaks the message of environmental protection, can be seen that the environment is very important to everyone.

Our upstream of the Yangtze river and Yellow River in recent years people cut down trees, not to protect the environment, make the Yangtze river and Yellow River upstream of the water and soil loss is very severe, Yangtze river flood, often have a lot of sediment in the Yellow River water. We in xinjiang tarim river is the longest continental river in China, the tarim river shore in iminqak is can be used to absorb dirt wont appear sandstorm, but people in the upstream of tarim river large area of forest cut water makes the river downstream dry, killing millions of acres of iminqak. It is barren land, to make more desertification. We in urumqi, family cooking, heating chimney come out large amounts of black smoke and exhaust emission of polluted air. Cant see the blue sky, the urumqi winter snow is black.

I saw on TV in South Korea restaurant use chopsticks are made of metal, can be used repeatedly. But in our country, large and small hotel is full use of disposable chopsticks, as far as I know a tree grow fifty years of birch only ten hotel with the number of chopsticks a day, how many restaurants are there in China? How much a day birch tree! !

To protect the environment, for students in our school must first from dont want disorderly garbage debris-brick, see someone littering to give him a reason. The adults also do not cut down trees, it will pollute the environment. To start from the save every drop of water, per kilowatt-hour, since the childhood to set up the consciousness of protecting the environment, to protect the environment, everyone duty. To make our home more beautiful!

环境是我们人类赖以生存的活动空间,比如说:空气的质量、工地和汽车发出的噪音、水质的好坏、街道的整洁和城市的美观等等都属于环境.现在每天在电视和报纸上都可以看见讲环保的消息,说明大家都很重视环境。

这几年我们的长江、黄河上游的人们砍伐树木,不保护环境,使得长江、黄河上游的水和土壤流失的很厉害,长江下游经常发洪水,黄河的水里有好多泥沙。我们新疆的塔里木河是我国最长的内陆河,塔里木河岸边的胡杨林是可以用来吸住泥土不会出现沙尘暴,可是人们在塔里木河的上游大面积开荒截水使得下游河水干枯,造成上百万亩的胡杨林死亡。至使本来就很贫瘠的土地,更加沙漠化。我们乌鲁木齐的人家做饭、取暖的烟囱冒出来的黑烟和汽车尾气的大量排放使的空气被污染。使乌鲁木齐的冬天看不到蓝天,雪也是黑的。

我在电视看见韩国的饭店用的筷子都是金属做的,可以反复用。可是在我们国家大大小小的饭店全是用的一次性筷子,据我了解一棵生长五十年的桦树只够十家饭店一天用的筷子的数量,中国有多少家饭店?一天要用多少棵桦树啊!!

对于我们校学生来讲要保护环境,首先要从不要乱人垃圾果皮纸屑,见到有人乱扔垃圾要给他讲道理。大人们也不要砍伐树木,这样会污染环境。要从节约每一滴水、每一度电做起、从小树立保护环境的意识,做到保护环境,人人有责。使我们的家园更美好!

Now, we know that the earth has been warming, cold place has melted the ice, the water level becomes more and more high, let many coastal countries. More land desertification, disasters are hit, make our life is no longer so carefree.

First of all, we must start from the side.

Forests have been cut down, automobile exhaust emissions... The first will directly affect our lives, because they let we dare not breathe. So, the best way to deal with these problems is to drive less, ride bikes, and riding a bike is good for you! . But although it has been said that and said more than once, but why there are so many cars on the road? So, this method really, a bit not practical.

The simplest is to plant trees, the trees are humans good friends, they can help mankind to many things, such as clean air, and so on. So, a variety of trees, this method is very practical!

In short, our earth wanted us to take good care of yourself, to protect, want to use practical actions to help the earth, make the environment more beautiful!

现在,我们知道地球已经开始变暖,寒冷地方的冰已经开始融化,变成的水使水平面越来越高,让许多沿海的国家被淹没。更多的土地沙漠化,天灾不断来袭,使我们的生活不再那么无忧无虑。

首先,我们必须从身边做起。

大片森林被不断砍伐,汽车尾气不断排放……这些首先就会直接影响到我们的生活,因为这些让我们“不敢呼吸”。所以,这些问题最好的解决方法就是少开车,多骑自行车,而且,骑自行车也很有益身体健康!。可虽然一直这样说,而且说了也不只一次,可为什么还是有那么多的车在路上呢?所以,这个方法实在,有点不实用。

最简单的就是种树了,树是人类的好朋友,他们能帮助人类许多事,比如净化空气啦,等等。所以,多种树,这个方法很实用!

总而言之,我们的地球要我们自己去爱护,去保护,要用实际行动来帮助地球,让环境更美好!

亲爱的同学们:

如果朋友有了困难,你会袖手旁观吗?如果朋友遇到危机,你会见死不救吗?我想你当然会说:“不会!”

现在我们人类的朋友——动物,有的已濒临灭绝,有的数量急剧减少,很难想象:如果有一天,人们生活在一个没有动物,没有植物的城市沙漠中,生命将逐渐枯萎,色彩将消失……

同学们为拯救动物,拯救人类,拯救唯一的地球赶快行动起来吧!因此我提出以下几点建议:

1、我们小学生要积极学习和大力宣传《野生动物保护法》,让更多的人了解并遵守这个法律。

2、现在有许多卖田鸡的。田鸡又叫“青蛙”,它可是人类的老朋友了,所以我们不仅不应吃它,还应告诉大家爱护它。

3、目前,伤害鸟类的事时有发生,致使许多小鸟无家可归,我们应该给小鸟做些巢,让它们安家落户,为人类做更大的贡献。

4、如果我们在路上遇到了小动物,我们应该做到“三不”:不恐吓、不打击、不捕捉。

5、如果我们捡到或发现了珍贵的野生动物,应及时向居委会、学校及有关部门报告。

我想:只要大家自觉遵守《野生动物保护法》,自觉维护生态环境,那么我们的祖国,我们的未来会更加美丽富饶。

Nowadays, with the improvement of the people’s living standard, some people form a habit of raising small or domestic animals as pets. Some raise small dogs or cats as their pets while others raise various birds or fishes as their pets. There are still even some people raising snakes and other unusual animals as their pets.

Does anyone have the same opinion of raising animals as pets? No, some people object to the idea of raising animals as pets. To them, animals have their own right to live a natural life like human beings. On the other hand, the way people raise animals as pets have a negative influence on the surroundings such as dogs’ barking at midnight, dogs’ chasing people on the street and so on. What’s more, some animals will transmit some diseases.

In my opinion, I do not like the idea to raise animals at pets. Animals have their own right to lead a life as they like. We should not deprive them of their natural right. In this way, we will live in a peaceful world in harmony with the other living creatures.

如今,随着人们生活水平的提高,有些人养成了饲养小动物或家畜作为宠物的习惯。一些养小狗或猫作为他们的宠物,而其他人饲养各种鸟类或鱼类作为他们的宠物。甚至还有一些人饲养蛇和其他不寻常的动物作为他们的宠物。

任何人都有相同的意见,饲养动物作为宠物吗?不,有些人反对将动物作为宠物饲养。对他们,动物有他们自己的权利,生活像人类一样自然。另一方面,人们饲养动物作为宠物的方式对环境有负面影响,如狗的叫声在半夜,狗追逐人在街上等。更甚的是,有些动物会传播某些疾病。

在我看来,我不喜欢养宠物。动物有他们自己的权利,过他们喜欢的生活。我们不应该剥夺他们的自然权利。这样,我们将生活在一个和平的世界中,与其他生物和谐相处。

these days, different ways are being taken to protect cultural identity。 obviously, not only is much contribution made to maintain old houses but also rules of laws associated with cultural protection are changed for the better。 some people even say that new buildings are right to be set up in the conventionalway。 i seem to be one of opponents who believe that the action can be unsuitable in our world。

one of the main reasons is that most of traditional buildings, in my nation, that offer provide few rooms can hardly hard to meet the demands for housing as increasing numbers of people pour into the city。 compared to before, today’s population has doubled and even trebled, which puts seriouspressure on housing supply。 as a result, new buildings must be substituted for old ones that have more efficient utility, even for some old buildings that have been damaged seriously。no doubts that building or maintaining traditional buildings is very essential to raise art sense and increase choices of people’s housing。 plus, these old houses are believed as very important resources to attract international visitors。 however, the proportionof traditional houses has to be under control, and otherwise the housing of citizens is badly affected。

overall, my view is that cultural identity is so preciousthat more efforts and measures should be taken but carefully。 the excellent tradition helps with deep understanding of history, and educates youths。 nevertheless a simple and recklessbehavior。 that new buildings are built in a typical way does more harm than good in the improvement of people’s being。
