保护眼睛的英语作业（优秀20篇）

however mean your life is,meet it and live it ;do not shun it and call it hard names.it is not so bad as you are.it looks poorest when you are richest.the fault-finder will find faults in paradise.love your life,poor as it is.you may perhaps have some pleasant,thrilling,glorious hourss,even in a poor-house.the setting sun is reflected from the windows of the alms-house as brightly as from the rich mans abode;the snow melts before its door as early in the spring.i do not see but a quiet mind may live as contentedly there,and have as cheering thoughts,as in a palace.

the towns poor seem to me often to live the most independent lives of any.may be they are simply great enough to receive without misgiving.most think that they are above being supported by the town;but it often happens that they are not above supporting themselves by dishonest means.which should be more disreputable.

cultivate poverty like a garden herb,like sage.do not trouble yourself much to get new things,whether clothes or friends,turn the old,return to them.things do not change;we change.sell your clothes and keep your thoughts.

I am a student from Xinhua Middle School in Chongqing，China. Informed that

you have a vacancy for a student to serve as the spokesman for animals, I cannot

resist my inner excitement,hoping to seize the opportunity to do something for

animals .

In my mind，nothing can delight me so much as caring for animals. Wherever I

go and whatever I do, I usually keep in mind that animals are angels from the

heaven, which bring us endless comfort and pleasure. I have been a panda lover

since my childhood. Panda is so lovely that brings fun to people and they are

regarded as the treasure of our country. Unfortunately，such a rare species is

now faced with the danger of being extinct。What I am eager to do is to raise

people’s awareness of animal protection and appeal to more people to care for

our earth companies.

It is my belief that all human beings can make a difference together. I

would appreciate it if my application could get your approval.

Pandas are my favourite animals. In fact, all the people like pands as well. Pandasliving in the wild can live for 20 years while the pandas that live in the zoos can have a life of more thqn 30 years. Pandas are really lovely. They can not only climb trees but also swim. However, the number of pandas is decreasing sharply. It is said that there are only 1000 pandas remaining in the world at present. It is sad news for all of us. Therefore, we are supposed to take measures to protect pandas in order to prevent them from dying out.

目前，濒危的动物正在日益剧增。如何保护濒危动物成了我们的当务之急。人们疯狂的捕杀动物，为了它们的肉、皮毛。我们这样做是不对的，因为动物是我们的朋友，我们应该保护它们，而不是将它们赶尽杀绝。大熊猫就是濒危动物的代表，它生活在森林里，以竹子为食，它们仅仅依靠着自然保护区生存。我们应该停止对动物们的捕杀，更好地保护它们

There are more and more endangered animals at present,so how to protect them has been our task of top priority . Its wrong for people to hunt animals for their meat and feather,for they are our good friends.We should protect them instead of killing them.Giant pandas,which are one of the endangered animals,live in the forests and live on bamboo lealves.They can just live safely in the natural protection zones.We should stop killing animal and protect them.

今上午第四节课，杨老师讲完了数学书上的知识点，又给我们评讲了练习册的错误，再带领大家重做了一遍口算题；突然，我觉得眼睛非常不舒服，很痒、很模糊，我轻轻揉了一下，本希望能“拨云见日”，但现实总是充满骨感，呈现在眼前的仍然如同打的马赛克一般朦胧；“难道我得了近视？怎么办？有这种可能性吗？不会吧！难道轻轻一揉就揉成了近视？我从今后就看不清楚了，难道我会永生永世得跟眼镜共同进步？不会吧……”。我心情如同晴空霹雳、万剑穿心，伤痛到了极点。我不甘心，再揉一揉，眼睛还是像打了马赛克一样模糊。瞬间，吵闹的操场上停止了嬉戏，空气也更冷了一分……，

正当我绝望之时，突然眼前一亮，原来的马赛克如同小鬼一样瞬间消失得无影无踪。原来是眼睛被讨厌眼屎给挡住了，顿时我放下了心中沉重的顾虑，心情也轻快许多。

通过这件事，我明白了眼睛对于每个人的重要性，我以后一定要保护好自己的眼睛。

真是吓死宝宝了。

The trickle of water was crystal clear, accompanied by the sound of the "ding dong" of the spring. The undulating mountain stands erect, majestic and overwhelming; The green trees, towering above the tops of the mountains, are not afraid to be afraid; The wild flowers, which are in the top of the mountain, are full of beauty and beauty, and the fresh flowers are pleasing to the soul. But that was all have become memories, is facing a murky water, batteries, plastic bags have polluted the land, industrial waste gas, automobile exhaust pollution the air, trees and flowers are hard to meet again, only can see is just a weak looking trees flowers and plants, all everything has disappeared, the earth on a red alert. The presidents of all countries have been together for three days and three nights... "The whole people moved to the moon," they were consulted, and they issued such an order. According to the scientists observed earth damage is too severe, human will not far from the end of the world, if you dont leave the earth, mankind had to count the days such as dead. The present moon, which has been constructed by human ancestors and modern humans, has been transformed.

The lush woods, the crystal clear water, the blue sky, and the various shapes of flowers and animals. "Wow! This is like a new earth, and it brings us back to the old days." people dont sigh. Yes, the moon has now and once the earth is almost the same as the air around the moon, the moons gravity, and thick atmosphere around the moon, everything seemed to go back to the once upon a time, people are living down here... "Wow! There are so many trees here! ", "wow! There are so many rivers here!" Greed once again led the human hand into the abyss...

For a long time, the moon returned to the earth and the earth was devastated, and everything on the moon was dead. All the pollution to the moon, the atmosphere became thin almost close to zero, tragedy staged again, once upon a certain day a diameter of 40 kilometers meteorite broke into the moon, because the moons atmosphere is too thin, almost no resistance, is this meteorite is easy to break into the moon, because there is almost no resistance, meteorite impact force is very big, hit ground surface cracked a big hole, the hot, liquid mass of molten rock from cracks in shock... Facing death of that a moment, human beings finally wake up, but the wake up, now is just unable to struggle, ridiculous human this time really redeemed himself again. The world has been destroyed, mankind has perished.

The earth is the mother of mankind, the earth is our common home. We like clear water, blue sky, like watching seagulls flying; we like ice Piao, like to listen to Greenfield roar; we like to fly warbler grass long, like to listen to birds singing; we like to see the sea in the early morning sunrise, like a few nights at least Stars days. We hope that our earth more beautiful and more beautiful.

However, due to irrational development, because the waste of natural resources, global ecological damage, pollution of all kinds more serious. Now, the world each year 600 million hectares of land become desert, 20 million hectares of forests are disappearing, the average of one hour there is a kind of species extinction. Also, the Earths temperatures are rising, the Antarctic ice cap began to melt, sea-level will continue to rise, many of the worlds coastal cities, islands, and large areas of land will be swallowed seawater. So, care for the environment is our common responsibility. As a small owner of Earth, we have to mind the world, look around. In life without one-time items; in a timely manner wash off the faucet; multi-curved waist do not litter anywhere in the threw peel; more than walk a few steps without crossing the green belt; many people around to remind the attention of environmental protection together.

Environmental protection is a long-term and arduous task, let us start from a small, start now to make our planet more beautiful environment, climate and better!

Animals Need Protecting

It is suggested that people have been aware of the issue--lack of preservation for endangered spieces, animals and plants, but as you see , they placed little efforts to cope with the problem.despite the versatility and intricacy of instruments , I would pore over some of the most striking ones and offer alternatives afterwards.

One of the major reasons , causing peoples inocence of protecting animals, is that the government did not function well as an educator, arosing peoples initiative in shielding wild animals, which led to the consequence that people do not know their responsibility to prevent animals from dangers, and specific knowledge in guarding them. what is equally important as the reason mentioned above is that media did not meet our satisfaction to inform the mass of the emergency which is crutial in arousing peoples conciousness to keep animals safe.

In spite of the serious problem, measure leading to profound improvement still can be taken. owning to the fact that funds are insufficient in some developing countries, developed countries or international organizations should shoulder more burden -- finacing them in order to capacitate them to accompolish the protection of animals. at the same time, education in telling people the way to make animals harboured ought to be focused on, thus resulting in peoples better awareness in the camouflage of our pla#from cutest creatures.

It is belived by me that if correct actions are taken to preserve animals, any kind of them will be far away from extinction forever.

Our society in constant development, our living standard has been improved, but my door but misses the point, that is environmental protection.

You see, lawn grass became yellow, and the roadside trees listlessly, dense forest under the handfuls of sharp saw also gradually away from us. This, but the fact that iron!

In the countryside, people cultivation of levelling, and so many trees lost their lives, however, these precious land because of improper use, was a wild field soil. In this way, a vast expanse of land with a large abandoned, year after year, day after day, past the dense forest will one day be a state long, become a piece of the other people hate the boundless gobi desert!

Everybody should know area Tuo lake, the biological variety there, especially the hairy crabs there, with a meat tender yellow, more and more the favour of people. Now, Tuo lake surface is covered by algae is full, the water had turned out to be a tan. And also the dead fish floating in the lake, garbage, and black water plant, are miserable sufferings

Careless human ah, you wake up, we live on the earth has not been able to afford, the forests on the earth in the sharply reduce, desert and wilderness is a miraculous increase. Clean fresh water resources is constantly reduced, however, dirty ChouShui river is in the unceasing increase, shouldnt, all is false?

Want people to listen to me a advice: please dont covet interests and cut down a tree, please dont waste water because of the naughty. Although these are only some things, but the cumulative up one by one and is a great thing. I believe that in the near future, our world will become more beautiful.

我们的社会在不断的发展，我们的生活水平也在不断的提高，可是我门却忽略了一点，那就是环境保护。

你瞧，草坪上的小草变黄了，路边的大树无精打采，茂密的森林也在一把把锋利的电锯之下渐渐的离我们远去。这，可是铁一样的事实!

在农村，人们垦荒造田，许许多多的树木就这样失去了生命，然而，这些宝贵的土地有因为使用不当，又被沦为荒田野土。就这样，一大片一大片的土地被荒废了，年复一年，日复一日，昔日那茂密的森林总有一天会一反长态，变成一片另人讨厌的茫茫的戈壁沙滩!

大家应该都知道五河沱湖吧，那儿的生物品种繁多，特别是那儿的大闸蟹，，以个大肉嫩、黄多而倍受人们的青睐。而现在呢，沱湖水面上皆被水藻覆盖满了，水竟然变成了黃褐色!而且湖水中还漂浮的死鱼、垃圾、还有黑乎乎的水草，真是惨不忍

糊涂的人类啊，你们醒醒吧，我们赖以生存的地球已经承受不了了，地球上的森林在急剧的减少，沙漠和荒野却奇迹般的增加。干净的淡水资源在不断的减少，然而，肮脏的臭水河却在不断的增加，难道，这些都是假的吗?

希望人们听我的一句劝告：请不要因贪图利益而砍树，请不要因为贪玩而而浪费水。虽然这些只是一些小事，但是一件件累计起来，就是一件大事。我相信，不久的将来，我们的世界将会变的更加美好。

Oceans becoming more acidicThe worlds oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.

Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.

Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.

眼，是我们最忠实的伙伴。它一直默默地为我们奉献，直到我们一生的最后一秒。它的工作是那么复杂，需要经过一系列传播物像，使我们产生视觉。但现在的我们，国家经济迅速发展，我们父母的年平均收入日益增长：“中国的发展不是以前那么落后，而是一条奔腾向上的龙。”

长时间看电视和玩电脑游戏使那些孩子眼睛大大受损，于是就成为了拥有“四只眼”的人。国家人民政府意识到这一威胁，会给我国的迅速发展带来障碍。为了祖国的未来，为了正个中华民族的利益……人民政府颁发：“九年免费义务教育”，还明确指出像我们这样的孩子，必须接受义务教育。这为中等家庭减轻压力，我们的学习经济压力得到前所未有的改善。但又给父母带来新的压力，我们在学习养成了一个非常不好的行为习惯。那就是：我们学习喜欢扒着写作业和看书等都把我们这双宝贵的眼睛靠桌面或书本很进，于是又拥有“四只眼”……

朋友：我们应该为祖国未来的美好而努力学习!但是，我们应该保护永远属于我们的眼睛!假如：“你的眼睛不好，你对得起赐于你肉体的父母吗?不要说肉体，就连精神你对得起她吗?”

Giant Panda is our national treasure, the state can be said for the protection of giant pandas put a lot of human and material resources giant now has been the worlds people the protection and care, which is a good thing, of course, the Tibetan antelope as the countrys animal protection , The National People have been recognized, however, this tiger? The poor will be extinct Siberian tiger who is going to have a genuine concern and care a little bit?

According to statistics, the Siberian tiger left at present, less than 20, still such a small number of these survive, has had imagined. Two years ago, in the mountains of Huanren, Liaoning found to be a man to die under the presentation of the Siberian tiger, from this we can see that the above countries and the people of the importance we attach to it, this first Manchurian tiger is actually how the dead do not Conclusion, and the other is only from the northeast where hu came to the place where the wonder and the third is the matter did not rise to the national media in particular. This really puzzled the other person you! Is it really the other tiger who fear love is not worth it, it really fate of the Siberian tiger so?

Towering mountains should not unique to human beings, should not have dense forest unique to human beings, rivers clear this should not be unique to human beings, the Siberian tiger survival of this nature should not be unique to human beings. Siberian tiger to the left of a piece of heaven and earth to survive it, the High IQ is the human species, there are still ways to leave that piece of local survival, and the tiger have to leave that piece of the local dead; you save tigers, is the human population control, engage in Family planning, and the Siberian tiger is scarce Rending it! Now we can hear the cries of tigers in the future even the Siberian tiger can be heard the cries.

星期五，张梓涵给我们讲了一节社会实践课，讲的内容就是要我们爱护眼睛，他先给我们出了一些近视的测试题，同学们有的不良习惯导致了他们近视，而有的同学有好习惯没有近视，这些好习惯，如果一直保持的话就会躲过近视，看完后他提出了一个问题，为什么会有近视的状况呢？同学们若有所思，不一会儿有的举起手，说是用眼不当，张子涵打开屏幕的下一页，上面有这个问题的准确回答。

1、用眼不当。

2、遗传亲人的基因。

3、光线导致近视。

4、挑食，缺维生素。

接下来下一个屏幕让人目瞪口呆，上面清晰的写着一段话，初中生和高中生近视眼的比例逐渐上升，小学生将近40%，青少年的近视率为全世界第一。同学们，有的窃窃私语在讨论着什么，有的难过的低下的头，有的眼睛瞪得大大的，还不时的叫着“哇”。

张梓涵又进入下一个问题，那又怎么能够预防近视呢？一个同学说道：“要多吃对眼睛有益的食物；少看手机、电脑，在近视后立刻去看医生；要在光线好的地方用眼，坐姿端正，多做眼保操”。“非常的棒”张梓涵说，他的脸上露出开心的笑容。

看班上有的同学都配上眼镜了，我们还这么小，肯定不舒服，所以大家要爱护眼睛。我们一定不要佩戴眼镜，我们要爱护眼睛，全班清晰而坚定的说，连张子涵，也不由得大声叫道。

眼睛就是心灵的一扇希望的窗户，它可以让人快乐的生活，可是班上有人配了眼镜，我们都为他们而难过，从此以后我一定要养成爱眼好习惯，做一个爱眼计划，同学们，一起加油哦！
