It was a fine day today and the sun was bright. I visited Beijing Zoo with my classmate, He Song. The animals were so interesting that all the people loved them. When a bear asked for some food by waving its ann, a visitor threw something to it. At once I went up to him and said without thinking,Dont do that. Its bad for it. If you really love them, take good care of them. His face turned red and answered he wouldnt do that again.

今天是个风和日丽的好天,我和同学贺松去了北京动物园。动物们是那么可爱,大家都非常喜欢它们。一只熊挥动着胳膊向人们要吃的,一个游客就投进去了什么东西。我想都没想就走过去说:“不要那样做。你的做法对它们没好处。如果真的喜欢它们,就应该爱护它们。”他的脸红了,并且回答说他不会再那么做了。

眼睛是心灵的灯。眼睛若是明亮,世界就光明;眼睛若是昏暗,世界就黯淡。如果没有眼睛,人们就只会“一事无成”。

你不要以为世上每个人都可以看见光明,有很多不幸的人生活在黑暗之中。我的爷爷就是一个盲人,他每次走路都必须要有人牵着他。不然爷爷就会到处碰壁,什么也做不成,所以我理解盲人不能看见万物的这种痛苦。

我很幸运,生下来就有一双清澈、明亮的眼睛。我第一眼看到的`是我的爸爸妈妈。我就是用这一双明亮的眼睛看到了大千世界:春天,我看见了五彩的小鸟正在蔚蓝的天空展翅飞翔,看见了绚丽多彩的鲜花绽放;看见妩媚娇嫩的野草娃娃迎风起舞;秋天,我用眼睛看见纷纷飘落的叶子与丰收的田野;冬天,我看见北国被冰雪覆盖了的大地。

上小学的时候,我就是用这双清澈、明亮的眼睛,看见了老师在黑板上写的每一个字、每一句话。我用我的眼睛探索科学奥秘,观察世界的变化……

有一双眼睛真好啊!我劝没戴眼镜的人,要像爱护生命一样,爱护自己的眼睛吧!

Man and His Environment

Throughout history man has changed his physical environment in order to improve his way of life. With the tools of technology he has altered many physical features of the earth. He has transformed woodlands and prairies into farms and made lakes and reserviors out of rivers for irrigation purposes or hydroelectric power. Man has also modified the face of the earth by draining marshes and cutting through mountains to build roads and railways.

However, mans changes to the physical environment have not always had beneficial results. Today, pollution of the air and water is an increasing danger to the health of the planet. Each day thousands of tons of gases come out of the exhausts of motor vehicles. Smoke from factories pollutes the air of industrialized areas and the surrounding areas of the countryside. The pollution of water is equally harmful. The whole ecological balance of the sea is being changed and industrial wastes have already made many rivers lifeless.

Now environmental protection is more pressing than ever before. As we know, massive destruction of environment has brought about negative effects and even poses a great threat to mans existence. Indifference to these problems will mean committing suicide. Therefore, effective measures should be taken and laws passed to conserve environment. Otherwise,man is certain to suffer from the serious consequences caused by this lack of care for his living surroundings.

It seems we are living in the conflict between modern and traditional cultures every day. Hearing the blaring of horns the moment you step out of your house, seeing the so called "pop" the moment you open your eyes, you cant help thinking, "Will the traditional culture be gradually lost?"

Many people believe so. They may put right in front of you all the evidences they can dig out. They may argue that people are rushing to restaurants instead of cooking at home, listening to pop music but not traditional, wearing in a way people couldnt imagine ten years ago. Modern people like the air of freedom, not to be restrained by traditions. They offer this long list, only trying to confirm that this world is full of fashion,competition and temptation and the traditional culture is fading

and will be lost at last.

Though we are now living in a world in which undeclared aggression, war, hypocrisy, chicanery, anarchy are part of our daily life. Though this is a skeptical age, and our faith has weakened, our confidence in some aspects of the traditional culture should and would never be lost.

Wouldnt you agree that our traditional culture is always credited with modesty, politeness and respectfulness, which have always been treasured for more than five thousand years?Even in this modern world, people still admire those with good manners, those who are polite to others or respectful to old people.

Wouldnt you agree that our Chinese traditional music is beautiful and artistic and our Chinese tea culture is always an appealing treasure to people around the world?

So there may just be some changes in our lifestyle or our attitudes towards life, but little change occurs to some fundamental aspects of our traditional culture that people still treasure in heart.

眼睛是心灵的窗户,可以让我们看到了世界万物,可有一些人因为用眼不当,所以戴上了眼镜。

又到了每周五下午的实践课,上课铃刚响,同学们就欢呼雀跃,因为大家都喜欢一起讨论问题。刚讲课时,张梓涵对我们提出了一个问题,为什么我们的眼睛会近视?同学杨阳说:“有遗传因素,还有用眼不当环境问题,”张子涵又说,当我们近视的话,需要多注意哪些方面呢?然后有的同学又说多注意饮食方面,的确如此,我们一定要多吃胡萝卜,多吃绿色蔬菜,多做眼保健操。

她还给我们讲了一些关于近视的内容,全国青少年近视为全世界第一,中学生们的比例逐渐上升,小学生为40%,刚提完这些内容以后,我们都很吃惊,有的甚至“啊”的惊讶的叫起来。所以,从现在开始,爱护眼睛,从我做起。

听完这些内容以后,我下定决心要控制我的近视度数,为了预防近视,我提出以下几点:

第一,不要在光线较暗的地方读书

第二,不要长时间的看电子产品

第三,注意读书写字姿势正确

第四,避免躺下或走路看书

第五,多开展体育户外活动

Once man did not have to think about the protection of his environment。 There were few people on the earth, and natural resources seemed to be unlimited。Today things are different。 The world has bee too crowded。 We are using up our natural resources,and polluting our environment with dangerous chemicals。 If we continue to do this, human life on earth will not survive。 We realize that if too many fish are taken from the sea, there will soon be none left。 Yet,with modern fishing methods, more and more fish are caught。We know that if too many trees are cut down, forests will disappear。 Yet, we continue to use powerful machines to cut down more and more trees。 We see that if rivers are polluted with waste products, we will die。 Yet, waste products are still put into rivers。

过去,人们不必担心保护环境的问题。因为那时地球上人口稀少,自然资源似乎取之不尽。如今,一切都改变了。世界变得拥挤异常。我们正在耗尽我们的自然资源,有毒化学制品的使用也正污染着环境。如果我们继续这样下去,地球上的生命将不复存在。我们都明白如果从海里捕捉太多的鱼,海里就不会再有鱼了。可是,现代化的捕鱼技术使得捕鱼量越来越大。我们都明白如果砍伐太多的树木,森林就会消失。可是,我们仍旧使用强大的机械砍伐越来越多的树木。我们都明白如果河水被废弃物污染的话,我们仅有死路一条。可是废弃物仍然源源不断地进入河里。

We know that if the population continues to rise at the present rate, in a few years, there won't be enough food。What can we do to solve these problems?If we eat more vegetables and less meat, there will be more food available。 Land for crops feeds five times more people than land where animals are kept。Our natural resources will last longer if we learn to recycie them。The world population will not rise so quickly if people use modern methods of birth control。

我们明白,人口继续照此刻这个速度增长的话,不出几年,就会发生食物短缺。我们该如何解决这些问题呢?如果我们多吃蔬菜,少吃肉类的话,我们就会有更多的食物。因为同样大小的土地如果种庄稼的话会比养殖动物多养活五倍多的人。如果我们学会再利用的话,自然资源就能持续更久。如果人们使用现代化的生育控制方法,世界人口就不会增长如此迅猛。

Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future。

最终,如果我们能够教育人们都意识到这些问题的话,未来我们就会有一个更好、更洁净的星球。

眼睛是心灵的窗户,没有了它,我们就无法看到那五彩缤纷、有趣、美好的世界了。

星期五上午,张梓涵同学给我们开始讲课了。一上课,她就自信满满地走上讲台,说:“同学们,现在开始上课!”刚开始,张梓涵就说了一件让我们谁都不敢相信的事:现在世界上近视率青少年就占70%,其中小学生就占40%。同学们听完这个数据后,反应各不相同,有的人张大了嘴巴、瞪大了眼睛,有的人在和同桌讨论着这件事,有的人还揪揪自己的耳朵,好想怕听错了一样,脸上还露出惊讶的表情……千奇百怪。只是大家都意识到应该好好保护眼睛。

她还在继续讲着“……”接着给我们出了一个问题:“近视的原因都有些什么?”紧接着杨洋同学和席上昀同学就争抢着回答,是因为遗传,看电子产品太多,用眼不当……。好多同学们也参与到这个问题当中来。这时张梓涵在黑板上给我们写出了正确的原因:第一,父母遗传;第二,用眼不当;第三,看手机、电脑等电子产品的时间太长;第四,用手揉眼睛……这些原因让我们深深地感受到了眼睛的重要性。然后,她又向我们提出了一个问题:“我们要怎么爱护自己的眼睛呢?”“看书的时候要在光线好的地方看,少玩电子产品,注意用眼卫生…。”等许多回答在她的话音刚落后出现。“对!就如同学们所说的那样。”在她优美生动的讲述中这一堂课很快就要结束了,最后在这节课临近尾声时,她又对大家说:“我们要保护什么?”她一边问一边还指着黑板上标题的空缺。“保护眼睛!”我们清晰而响亮的回答。

大家都要好好爱护自己的眼睛,不要因为我们的原因而给它戴上一个枷锁(眼镜)。眼睛是看见美好世界的窗口,也是我们认识世界,学习知识,相互交流的重要窗口。只要大家努力去做,我相信我们每个人都会有一双明亮、有神的大眼睛。

导语:关于环境保护英语作文怎么写?以下是小编精心为大家整理的有关关于环境保护的英语作文,希望对大家有所帮助,欢迎阅读。 关于环境保护的英语作文1

There are more high-rise apartment buildings built in the city we live to accommodate more city dwellers. To make room for these constructions, a large number of trees are cut down. We have to be constantly afflicted with the noise and air pollution everyday. Obviously, we are paying the cost of the development.

Even the most developed countries are troubled with environmental issues. In fact, the more developed the country is, the severer the problem has. To maintain our economy prosperity and stability, we have to be in full operations and spread the workload in industry fields. As a result, we may seek temporary economic development at the expense of the environment and resources. The consumption of natural resources has been a big problem. It is admitted that the world economy is booming with the satisfaction of environment. However, we have made a blunder by equating material prosperity with better living standards.

A better life should be a life closer to nature. The modern lifestyle is best characterized by hectic, mass-productive and seemingly comfortable. But actually something originally natural and invaluable has been lost. We are no longer able to breathe fresh air, take a walk in the woods or even look at the stars in the sky as the stars are obscured by smog and artificial lights.

Hence, we need to curb the quick tempo of life in order to protect our environment and ironically improve our life. Science and technology thus should be employed to create a harmonious relationship between mankind and nature. A better environment means much more than material comforts. Besides, by slowing down a little bit, our life would turn out to be less stressful. To have a better life, we need take effective measures right now.

The current environment damage stems from the misguided conception that material wealth is equivalent to a better life. In reality, environmental protection serves as the catalyst of our very pursuit of better life rather than a deterrent 关于环境保护的英语作文2

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

In the stream next to the road, there is a trash, in the trash next to, there are a lot of garbage: rotten apples, dead mice, Coke cans ... ...

Roadside, people coming and going, bustling, withering. They are talking and laughing, some people eat snacks, the garbage to the direction of the trash to throw; some people through here, smell the stench, clutching his nose hurriedly left; there are people Mamalielie, his face exposed Hated look. But no one is going to clean up the rubbish.

That day, Hasty and Showtime chest wearing a bright red scarf went to school. In the moment after the trash, they stopped, looked at the show, Showtime, said: "Hasty, we clean up the garbage!" Xinxin bent down, rolled up the sleeves, picked up the garbage into the Trash, they are not too dirty, even dead rats, dead cockroaches have not let go.

After the garbage, the winter and winter from the bag out of the pen and paper, touched the back of the head, waved "brush" to write: "civilization - only one step!" And then paste the slogan to the trash Warned passers-by.

I have heard such a story -

In a Korean home, there is a handy paper was blown away by the wind. He chased him all fifteen minutes on the street and threw it into the trash. The reason is not because of their own to bring pollution to the earth.

The earth gives the essence of the material, and in the end, it is from the people that the rebate is rubbish.

Treat the earth is to treat yourself. Save the earth is to save the future. So we want to start from today, from their own to protect our Mother Earth.

Protect the environment by everyone!

在川流不息的马路旁边,有一个垃圾桶,在这个垃圾桶的旁边,有很多垃圾:烂苹果、死老鼠、可乐罐......

路边,人来人往,熙熙攘攘,擦肩接踵。他们有说有笑,有的人吃完了零食,把垃圾往垃圾桶的方向丢去;有的人经过这里,闻到恶臭,捂着鼻子匆匆离去;还有的人一边骂骂咧咧,脸上露出了讨厌的神情。但是就是没有人去清理垃圾。

那天,冬冬和欣欣胸前戴着鲜艳的红领巾上学去了。在经过这垃圾桶的瞬间,他们停下了脚步,看着看着,欣欣说:“冬冬,我们把垃圾清理干净吧!”欣欣弯下腰,卷起衣袖,把捡起了垃圾放进垃圾桶,它们不嫌脏,连死老鼠,死蟑螂也没有放过。

收拾后垃圾后,冬冬从书包里拿出纸笔,摸了摸后脑勺,挥笔“刷刷”地写到:“文明——只差一步!”然后把这标语贴到垃圾桶上,以告诫路人。

我也听过这样一个故事:

在一个韩国人的家里,有一张可要可无的稿纸被风吹飞了。他整整在街上追了十五分钟才追到,然后把它扔进垃圾桶里。原因是不想因为自己给大地带来污染。

大地给予所有人是物质的精华,而最后,它从人们那里得到的回赠都是垃圾。

善待地球就是善待自己。拯救地球就是拯救未来。所以我们要从今天做起,从自己做起,保护我们的大地母亲。

保护环境靠大家!

In order to protect the animals; Countries in the region to build the zoo; In addition, in some areas also establish nature reserves and scenic spots. Also has the provincial forestry bureau and the municipal forestry administration in provincial regions; And in the forest with police station; Countries with the level of national grade a few animals in the animal kingdom; Separately promulgated and issued by the state laws to protect animals and files.

If human repeat ones mistakes, then the home to the survival of humans will be destroyed by human hands.

We have to live like animals, if we kill all the animals on the earth, eventually hurt ourselves.

We is a friend of animals, animals are our friends, is a friend of survival in survival.

We want to protect animals, let them give us the benefit, its our duty to protect animals, so it is urgent to protect the animals.

I come to the conclusion that a rong shame: "in order to protect the animals, ashamed of killing animals".

一说到动物,人们就想捕回去杀死吃它们的肉和刮下它们的皮毛来赚钱,可是人类万万没有想到的是由于乱捕滥杀等对待动物,使得动物的种类一天天减少,而有的动物已经到达“濒临灭绝”据新闻报道:野生东北虎在我国不足500只、而非洲象只有约47至69万只、长江江豚不到1500头、而东部美洲狮已经灭绝、白令海牛也已经灭绝、也使生物圈和食物链遭到严重破坏,这都是人类在地球上一一所犯下的罪行,我们要保护这些美丽的生灵、保护生物圈、保护食物链。

为了保护动物;国家在各个地区建立动物园;除此之外,在一些地区还建立自然保护区和自然风景区;另外还在各省各地区设有省级林业局和市级林业局;还有在森林设有森林派出所;国家在动物界设有国家几级动物的级别;国家还分别颁布和颁发了保护动物的法律和文件。

如果人类一错再错下去的话,那么这个人类赖以生存的家园就会毁于人类手中。

我们和动物一样都要生活,如果我们把地球上的动物全部杀死,最终伤害了我们自己。

我们是动物的朋友,动物也是我们的朋友,是生存在赖以生存的朋友。

我们要保护动物,让它们给我们造福,保护动物是我们的责任,保护动物刻不容缓。

我总结出一条一荣一耻:“以保护动物为荣,以捕杀动物为耻”。

Now, "environmental protection" has become a global focus. But to truly protect the environment, we must start from ourselves and start with the small things around us.

One day, I went to play in the small river in the park. A little boy wanted to throw a fresh bottle into the river. I looked at it and said, "no matter what, Im going to play. If I take care of him, I wont be able to play." But at this time, one is old man on a fishing trip saw the little boys behavior quickly held out his hand to stop a small boy, and said to the boy: "child, dont throw rubbish into the river." The little boy listened and put down the bottle and said to the old man, "whats the big deal? Besides, this is a bottle, not a garbage." The old man listened and was not angry. Smiled and said to the boy, "son, you dont understand. You dont see it as a bottle, but it will also be like other garbage pollution water. We cant drink clean water. Moreover, the trash can is over there, a few steps away." The little boy was speechless to the old man. He said "thank you" to the old man and ran to the trash can.

I listened to that thought, "thats right. When we want to throw fruit peel, tend to throw the rubbish casually into the trash can outside, and ignored. In fact, as long as you stretch out his hand, will be thrown into the trash can. Sometimes, you can throw some wrapping paper with a, then a walk it. Later, you said cant find the trash can. In fact, trash can in a few steps away." These little things can reflect a persons moral character and whether he loves the environment around him.

Protect the environment. Its all about us. Everyone has to do their part. This will make our home more colorful!

他是位略显严肃的中年男教师,个子不高,稍稍有点胖。远远见他,你会觉得他无异于这个年龄的其他男子,但当你走进他的课堂,或与他近距离交流些许,你定会为他那双会说话的眼睛所引吸。两片厚厚的眼镜片后面,他那双眼睛显得格外特别。那双眼睛充满智慧与学识,启迪学子的思想,开阔学子的视野;那双眼睛充满期待和赞许,总是给人以力量和信心;那双眼睛,犀利而又严厉,督促你自觉地自省言行;那双眼睛亲切而又温情,在我遇到困难的时候,给我无穷的勇气,在我跌倒的时候,又像一只温暖的手把我扶起……

他曾为我们教过语文课,课堂上的他坦然、从容,眼神坚定,总是用一个又一个问题引导我们思考。提问时,他一改平日的严肃,微笑地注视着同学们,眼神中充满了期待与鼓励。我就是在这样的期待与鼓励下,一次次勇敢地举起了手,在他的赞许中慢慢找到自信。

这样的鼓励时时发生着,并且激励着每一个他深爱的学生。一次篮球比赛,由于本来就与对手有矛盾,大家带着情绪上场,求赢心切,结果连输数局。失败的我们跑进教室大耍孩子脾气,一伙人又哭又闹。他走进教室,把我们一个个拉起来,

“只不过是一场友谊赛而已嘛,要把它当作一种艺术来欣赏,不要把它当作是一场决战!”说完,他笑盈盈地望着大家,眼神亲切、慈爱,如同对自已孩子的无言关爱。“没关系,下次我们一定赢!”,望着他的眼睛,我们没有继续哭下去,而是和他一起笑了。

但有的时候,他的眼睛又是犀利而又严厉的。当我扔下没有吃完的早餐;当我考试时不自觉地掏出小纸条;当我缺乏宽广的胸襟,与同学发生矛盾时……这个时候的他,即便不说话,他的眼睛也能让你感到惭愧。他用目光让你知错,他用目光让你改错。

就是这位老师,他用那慈爱、和善、充满信任的眼睛,填平了师生间情感的沟壑,架起了同学间友谊的桥梁,使大家和睦相处,充满团结互助的和谐气氛。

他为我们付出了父母般神圣的爱,他赐予了我们搏击风浪的翅膀,翱翔于理想的万里苍穹,引导我们迈开娇健的步伐,踏上广袤的神州大地。

他——我们的班主任罗老师。

Now in the era of rapid development, drive a car at work, waste water and electricity, such as timber has been used to it. And is this a series of moves, people are destroying the scar to the earth, environmental protection has been forgotten by the people.

I saw advertised in the country for a year only food waste is equivalent to pour out the ration of two hundred million people a year, this is an astounding number, thus we can see the waste is huge. Moreover, Chinas waste is not a little, we do not pay attention to the automobile exhaust, the harm of battery is buried in the soil... Thus China has become a "waste of power.

How can I be eco-friendly? This is a simple and complex problems. I think "starts from the minor matter" is the answer to this question, never throw rubbish casually, from shopping after all bring their own shopping bag, start from go out by bus more, since to use less disposable chopsticks, lunch box... Environmental protection needs to be done? Eat less animals, with environmental protection batteries, use less air conditioning, water reuse, conveniently turn off the faucet, will waste paper recycling and so on many ways, as long as it contributes to the environmental protection way, is environmentally friendly.

Environmental how many, how much your moral, environmental protection, how much you love how many, how many green, you how many character. From now on will do a green, understand environmental protection, people to protect the environment! Make the earth a better place, let the life become more beautiful, make people more beautiful!

Let the green, everywhere!

在时代飞速发展的现在,上班时开汽车,浪费水电、木材等已经习以为常了。而就是人们的这一系列举动,正在摧毁着伤痕累累的地球,环保已被人们遗忘在脑后。

我在广告上看见全国一年仅餐饮浪费就相当于倒掉了两亿人一年的口粮,这是一个惊人的数字,由此可以看出我们的浪费是巨大的。而且,中国的浪费不是一点点,我们从不注意汽车排放的尾气、电池埋在土里的危害……由此中国成了一个“浪费大国”。

怎么才能做到环保?这是一个有简单又复杂的问题。我觉得“从小事做起”才是这道题的答案,从不把垃圾随便一扔做起,从以后购物都自带购物袋做起,从出门多乘公交车做起,从少用一次性筷子、餐盒起……环保需要做什么?少吃动物、用环保电池、少用空调、把水重复使用、随手关水龙头,将废纸再次利用等许许多多的方式,只要对环境保护有贡献的方式,都算是环保。

环保有多少,你的道德就有多少,环保有多少,你的爱心就有多少,环保有多少,你的人品就有多少。从现在起做一个会环保,懂环保,做环保的人吧!让地球变得更美好,让生活变得更美好,让人们变得更美好!

让环保,无处不在!
