保护眼睛的英语作业【汇总20篇】

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.

Animals Need Protecting

Earths biological diversity is being fast decline of many species facing extinction. Threat to the survival of wild animals and plants is a major factor in habitat loss, business development, and wild animals and plants and their products in international trade. Resources are limited, it is necessary for the endangered species, to propose specific measures of protection level. We can formulate the corresponding endangered species laws, application to establish nature reserves, endangered species breeding centers, means of conservation biology, endangered species, the implementation of in situ conservation and ex situ conservation. At the same time, we must restrict international trade in Endangered Species of Wild Fauna and Flora, to make laws to protect endangered species.

Recently, our efforts to protect wild animals was questioned by the public,

because the news is keep reporting that more and more wild animals was killed by

human beings, especially the very precious one. Innocent animals was dead for

their meat, fur and tooth, it was just used to fill up human beings desire. In

my point of view, the wild animals were protected effectively still has a long

way to go.

Firstly, people should try harder to make a better place for animals. The

land where the wild animals live was deprived by human being. For hundreds

years, people cut the trees to make land for their living and farming, wild

animals homeland was took, they have no choice but run away. What is more,

human beings break the food link in nature; wild animals can not find enough

food to keep alive. There is no doubt that the destruction of nature has become

a big problem to kill wild animal, for instance, a polar bear was starved to

death because of the greenhouse effect, the ice was melt away, the seadog and

fish that polar bear like to eat are far away from them. For those reasons,

people should protect the environment first if they want to protect wild animals

effectively.

Second, no buying, no killing. Some rich people like to wear fur coat, they

treat it as a status symbol, especially for rich woman, they think animal fur is

beautiful and warm, they will never consider that the fur they wear for years is

the skin that animal wear for their whole life, and they knew how bloody when

people took the fur from animal but they choose to ignore it. If people do not

buy the fur and tooth, lots of wild animals will be survived.

In sum, wild animals are our friends, we should give back and protect their

homeland, and stop buying their body part, or our future generations will see

them in zoo and museum.

The earth is our mother, is the survival of our homes. With the improvement of living standards, while enjoying the human, but unknowingly destroyed her, our living environment is deteriorating.

At ordinary times is ok, we eat a piece of gum, chewing freely to spit on the ground, after chewing gum stuck firmly on the ground, cleaning workers to use shovels to get it off, and gum also pollute the land. We often when shopping, use large and small plastic bags, plastic bags but dont know by fire, and produce toxic gases after the landfill is not easy to degrade after, can also lead to land is destroyed, the population of China is so much, you can imagine how many plastic bags in the pollution of our environment.

A persons environmental action is like a lamp, when everybody lit the lamp, the whole world would be bright! Lets get started! Dont eat chewing gum; Dont use plastic bags; Dont use disposable chopsticks... Protect the environment, everyone duty! Let our earth more beautiful!

地球是我们的母亲，是我们赖以生存的家园。随着生活水平的提高，人类在享受的同时，却在不知不觉地破坏她，我们的生存环境不断恶化。

平时没事时，我们就吃一块口香糖，嚼完后随口吐在地上，口香糖牢牢地粘在地上，清洁工人得用铲子才能把它弄掉，而且口香糖也污染土地。我们经常在购物时，会用到大大小小的塑料袋，却不知塑料袋被火烧后会制造有毒气体，填埋后还不容易降解，还会导致土地被破坏，中国人口这么多，可想而知会有多少塑料袋在污染我们的环境。

一个人的环保行动就像是一盏灯，当大家都点燃自己的那盏灯，整个世界就会一片光明!让我们行动起来吧!不吃口香糖;不用塑料袋;不用一次性筷子…保护环境，人人有责!让我们的地球更加美丽!

The eyes are the window to the soul, is important way to obtain all kinds of knowledge. We cannot leave the eyes everywhere in life, if without eyes, the world will become a dark, if we have a problem with my eyes, study and life will encounter many difficulties. In spite of this, we have a lot of people still dont cherish the eyes. Around me, there have been more and more students take the "small glasses son", my eyesight also gradually decline, doctors diagnosed later pseudomyopia. Eye protection, therefore, it is taken seriously by more and more people.

In school, the teacher often give us some effective method to protect your eyes, for example when homework hand want to leave the tip of one inch, belly to a punch from the desktop, head to a foot away from books, to read in the right place, but also often do eye exercises. But these are the most easily ignored by the students.

What people wear glasses fast increase? The question in my mind kept wandering. Later, I looked at a very long time, also check the information from the Internet, finally reached the conclusion. The first big reason: no scientific methods to protect their eyes. Some classmates for a long period of time reading books, watching TV, Internet access, make the eye often is in a state of fatigue, and do not pay attention to eye health. Although our school asked the students are doing eye exercises on time, but part of the students or not to do a good job, some still hiding under the table. The second reason: genetic. Some parents are nearsighted, and pass on to their children. But this kind of situation seems to be not much, "small glasses," often because not sparing eyes.

Finally, counsels: we must cherish oneself only this pair of eyes, to make our every day is full of light!

眼睛是心灵的窗口，是获得各种知识的重要途径。生活中我们处处都离不开眼睛，如果没有眼睛，世界将会变得一片黑暗，如果我们的眼睛出了问题，学习和生活将会遇到很多困难。尽管这样，我们有很多人还是不爱惜眼睛。在我的周围，已经有越来越多的同学带上了“小眼镜儿”，我的视力也逐渐下降，后来被医生诊断为假性近视。所以，保护眼睛这一点也被越来越多的人们重视起来。

在学校里，老师常常会交给我们一些保护眼睛的有效方法，例如写作业时手要离笔尖一寸，肚子要离桌面一拳，头要离书本一尺，要在正确的地方看书，而且还要经常做眼保健操。但这些却最容易被同学们忽视。

到底是什么让戴眼镜的人飞快增加呢?这个问题在我的脑海里不停地转悠。后来，我观察了很长的时间，也从网上查了资料，最终得出了结论。第一大原因：不用科学的方法去保护眼睛。有的同学长时间的看书、上网、看电视，使眼睛经常处于疲劳状态，并且不注意眼睛卫生。虽然我们学校要求同学们都要按时做眼保健操，但一部分同学还是不好好做，有的还躲在桌子底下。第二大原因：基因遗传。有的父母是近视眼，并遗传给了自己的孩子。不过这种情况好象不多，“小眼镜儿”往往是因为不爱惜眼睛造成的。

最后奉劝大家：我们一定要爱惜自己仅有的这一双眼睛，使我们的每一天都充满光明!

Traditional Culture Wont Be Lost

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.

The traditional culture will never be lost, I believe.

At present,the endangered animals are increasingly fast.How to protect them become our priority.People are crazy about killing animals for their meat, fur.But it is wrong because that animals are our friends, we should try to protect them,instead of killing them to die out. Pandas are represents of endangered animals, which live in the forest and live on bamboos for food. They only depend on the nature reserves to live. We should stop killing animals, and protect them better

Its our duty to protect ourenvironment. Where do we live? The earth. The earth is the only one place we live in. So you know how important the environment is.

保护环境是我们的义务。我们居住在哪里？地球。地球是我们唯一居住的地方，所以可想而知环境对于我们的重要性。

But now, some people are harming the environment, like cutting down trees, drawing pictures on public walls,litteringonto the ground. Its terrible if we still do it.

但是现在，很多人都在破坏环境，比如砍伐树木，在公共墙壁上乱涂乱画，随地扔垃圾。如果我们继续这样下去是非常可怕的。

Now, its time for all the people in the society to protect the environment. Its our duty. It needs each of us to make a contribution to improving the environment. We should make our environment more and more beautiful.

现在，是人们保护环境的时候了，这是我们的义务，我们都要为改善环境做贡献，我们应该努力让我们的环境变得更好。

here are many kinds of animals in the world,but not only the humans.we live in the same world,and we should be friends.as everybody knows,the humans are the rulers of the world today,so we should protect our friends--the animals!

But how to protect them?as first,i think we must stop killing the rare birds and animals,especially the young ones.the second,we have to protect the environment,to make the sky blue,to make the grass green,to give the animals a comfortable space to live

In the past, there have been many endangered animals. Now they are extinct. Does it matterHas our environment been affected by their absenceHas the quality of our own life been changedThe answer to these questions is “Yes.”

It does matter if we destroy an endangered species habitat to develop more farmland, housing or industrial parks.It will effect all the other creature.

For example, if certain trees are cut down, birds and bats will have no place to roost.They cannot roost, they cannot breed. If there are no bats or brids, there will be no animal to eat certain insects that plague our crops.

Jungle around the world are being cut down to make room for humans. We will never be able to see or study this fragile ecosystem.

Human beings should be responsible for their own acts of nature. The promulgation of laws to maintain ecological balance, to make more space and natural. Conservation biology, Protect environment, protection of natural.

Panda is our country’s treasure, we should protect it. nowadays, we see from the TV that panda is less than before, it is not only because of the damage of the environment, but also the weakness of the panda. Everybody loves panda, it is so lovely, a panda has two black eyes, it is very lazy, it likes sleeping all the time. When we see its round body shape, we can’t help loving them. In order to see the lovely animal, we need to protect them. We must protect the environment, like not to throw the rubbish away, not to cut down the trees. We condemn such behavior that killing the animals. Protecting the animals is everybody’s job.

熊猫是我们国家的珍宝，我们应该保护它。现在，我们可以从电视上看到熊猫比以前少，这不仅因为环境的破坏，还因为熊猫自身的脆弱。大家都喜欢熊猫，它很可 爱，熊猫有两只黑色的眼睛，很懒，总是在睡觉。当我们看到熊猫圆圆的身形时，忍不住喜欢它们。为了看到这些可爱的动物，我们需要保护它们。我们必须保护环 境，比如不随处扔垃圾，不砍伐树木。我们谴责杀动物的行为。保护动物，人人有责。

导语：随着环境污染问题的严重加剧，越来越多人认识到保护环境的必要和重要性，下面是yuwenmi小编为大家整理的优秀英语作文，欢迎阅读与借鉴，谢谢!

Nowadays more and more people realize it`s necessary and important to protect the environment. Alsothere are some people who don`t pay attention to hygiene and they can`t stop littering the rubbish casually or spitting everywhere all the time.And in addition there are a few factories often cutting down the trees discharging chemicals and dirty water and so on.And it causes many problems like the Greenhouse Effect.If they do these day by day and our life will be harder and harderso we have to stop them. To stop them we can put up commonweal advertisements and tell them the detriment of destroying the environment.So we can start from now to make a beautiful life.

【参考译文】

如今，越来越多的人认识到环境保护的必要和重要性。同时，有些人整天都不注意卫生，而且他们不能停止乱扔垃圾或者随意，随地吐痰。此外，还有一些工厂经常砍伐树木，化学品和污水排放等。并导致像温室效应问题很多。如果他们现在这样做，我们的生活会越来越困难，所以我们必须阻止他们。阻止他们，我们可以贴公益广告，告诉他们破坏环境的危害。所以我们可以从现在开始做一个美好的生活。

Animals are natural resources that people have wasted all through our history.Animals have been killed for their fur and feathers， for food， for sport， and simply because they were in the way.Thousands of kinds of animals have disappeared from the earth forever.Hundreds more are on the danger list today.About 170 kinds in the United States aloneare considered in danger。

Why should people care? Because we need animals， and because once they are gone， there will never be any more。Animals are more than just beautiful or interesting.They are more than just a source of food.Every animal has its place in the balance of nature.Destroying one kind of animal can create many problems.For example， when farmers killed large numbers of hawks， the farmers stores of corn and grain were destroyed by rats and mice.Why? Because hawks eat rats and mice， with no hawks to keep down their numbers， the rats and mice multiplied quickly。

Luckily， some people are working to help save the animals.Some groups raise money to let people know about the problem.And they try to get the governments to pass laws protecting animals in danger.Quite a few countries have passed laws.These laws forbid the killing of any animal or planton the danger list.Slowly， the number of some animals in danger is growing。

吸烟对健康的危害往往使人想到呼吸系统疾病，可是吸烟还会导致视力受到影响，这不是危言耸听。

吸烟对眼睛造成最常见的危害是弱视。弱视，就是矫正视力低于0.8。吸烟导致弱视的原因，一是由于吸烟时人体吸入的氧气被消耗，致使血中氧的含量下降，而眼视网膜对缺氧格外敏感，长期下去，视神经纤维会发生变性，视网膜乳头黄斑区也会发生萎缩;二是烟草燃烧时产生的烟焦油会导致体内维生素B12的含量下降，而维生素B12是维持视神经正常功能所必需的营养物质。在这两者共同的影响下，使得吸烟者视力下降而发生弱视，严重者可致失明。

据医学家调查，在白内障病人中有20%与长期吸烟有关。而每天吸烟20支以上的人与不吸烟者相比，患白内障的可能性要高2倍。

另外，吸烟时吸入的尼古丁及一氧化碳等有害物质会使血管收缩、血小板凝集力亢进，由此导致视网膜中央血管栓塞、黄斑变性等致盲性眼病的发生。临床还观察到，吸烟者有时会有一过性眼压升高的现象，这在青光眼患者中尤为明显，青光眼病人本来眼压就高，如果再吸烟，无疑是雪上加霜。

同时，科学研究还明确指出，烟草也会导致眼睛周围的皱纹产生。即使自己不吸烟，也不应放松警惕，“二手烟”“三手烟”同样会摧残身心和容貌。因此，我们还是和烟草保持一定距离吧。

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.

Recently, a large number of affairs about sexual assault were disclosed and reported by mass media. As far as I am concerned, people should get some enlightenment from these affairs, such as enhancing and strengthening education inSelf-protection awareness, especially for children and students.

最近，有很多关于的事件媒体揭露和报道。我认为人们应该从这些事件中得到一些启示，比如，提高和加强自我保护意识教育，特别是对于儿童和学生。

Children and students are hurt most in this kind of affairs. As a result, to enhance and strengthen their self-protection awareness is indispensable. In addition, to strengthen the awareness of defending danger is also important. If they can realize the potential danger from someone or something before it happens, they can make some preparations to avoid the danger and reduce the rate of being hurt.

因这类事件伤害最大的是儿童和学生。因此，提高和加强自我保护意识是必须的。此外，加强防范危险的意识也是很重要的。如果他们能在事情发生前意识到某人或某事的潜在危险，他们就可以做一些准备来以避免和减少受伤率。

Therefore, I advocate that parents should help their children develop self-protection awareness from birth, such as designing some situation for them to cope with. In addition, parents should teach their children to recognize the danger and how to avoid and reduce the danger from outside. Besides, children also need to develop an excellent ability of observation.

因此，我认为父母应该帮助他们的孩子从出生开始就培养自我保护意识，比如，设计一些情况来让他们应付。父母还应该教导孩子认识危险，如何避免和减少来自外界的危险。此外，孩子也需要培养优秀的观察能力。

In a word, to protect children needs both the effort of parents and children themselves.

总之，保护儿童需要家长和孩子他们自己的努力。

water is very important for us.

we must drink water everyday. we can’t live without water. water is everywhere around us. at home, we use water to wash clothes, to wash dishes, to cook rice, to clean the flat, to have showers, to make drinks, to clean our teeth, to have a bath and so on.
