保护视力的优秀英语作文（精品20篇）

ver 70% of the Earth’s surface is water; water is obviously the most precious natural resource that exists on our planet. Without water, life on Earth would be non-existent. Water is the lifeblood of the environment, essential to the survival of all living things-plants, animals, and human. Although we recognize this fact, we disregard it by polluting our rivers, lakes, and streams. Afterward, we are slowly but surely harming our planet to the point where organisms are dying at a very alarming rate, and our drinking water has become greatly affected. In order to fight against water pollution, we must understand the problems and become part of the solution; we also need to do everything possible to maintain its quality for today and the future.The government alone cannot solve the entire problem; it’s up to us when it comes to the problems we face with our water. In your home, correctly dispose dangerous household products. Keep paints, used oil, cleaning solvents, pool chemicals, and other dangerous household chemicals out of drains, sinks, and toilets because many of these products contain harmful substances. In your yard, recycle used motor oil. Avoid pouring waste oil and resist the temptation to dump wastes onto the ground.These are just a few of the many ways in which we, as human have the ability to combat water pollution. If these measures are not taken and water pollution continues, life on Earth will suffer severely.

动物是我们人类的好朋友，我们不能伤害它们，但有些人却为了自已的利益，不顾那些可怜的小动物的生命，去践踏它们，捕杀它们。

记得那是今年暑假的一天，我和姥姥在公路的一边坐着聊天，我看见一只小猫想穿过马路去吃对面的一块肉，谁知，小猫刚走到马路中间，一辆大卡车过来了，司机先生一边按喇叭，一边嘴里骂道：“死猫走开。”小猫还没理解了司机的意思，司机先生已不耐烦了，他一踩油门，一个小生命就这样死在了满载货物的大卡车的车轮下。我看着这一幕又气愤又伤心，为了纪念这只可怜的小猫，所以我想把这一天——7月2日设立为保护动物节。

到了每年的这一天，人们都要为保护动物做贡献，要让小动物轻松愉快地度过这一天，不能让它们受到伤害，小动物不管到了谁家，人们都要热情招待它们，最后，我们还要用各种不同的方式去宣传小动物对人类的帮助。让世界上的每一个人都要保护小动物。

我盼望这个节日早日诞生。

China, as a developing country, has a large gap compared with developed

countries. If we want to catch up with and even surpass the developed ones,

education seems important and should be given the first priority. Besides,

education seems the same important to individuals.

In modern time, when science and technology are making great progress, the

education of the work force is the most important. Moreover, many of the success

in advanced countries have demonstrated that a nations prosperity mainly

depends on the quality of its labor force, namely those who have been well

educated.

For individuals, education is the best way to improve oneself. Firstly,

its education thathelps people gain basic knowledge of the world, helping them

to distinguish what is right and wrong. Secondly, education improves ones

skills of life and work, which can make people live a good life or have

achievements in career. Finally, education brings people ability of learning and

说起眼睛，那一直是我的骄傲。

每当别人问起我的视力，我总是装作若无其事地说：“还好，还好，也就是1。5啦。”这样的回答总会引来对方的一阵赞叹。也正因为我的视力一贯如此，不由得就放松了警惕：趴着写作业、躺着看书;一个礼拜要看3小时的电视、玩1小时的电脑……日子过得轻松自在，却没想到倒霉的近视大师还是粘上了我。

上一学期期末，体育老师查视力。我像往常一样，信心满满地站在了白线的后面，漫不经心地用右手蒙住了眼睛。啊?怎么看不见那最下面的一排?我抹了抹眼睛，想看得更清楚些，可这下却更加模糊了。最后，我只好硬着头皮测完了视力，老师说：“0.9、1.2”

天哪!我的视力从来没有这么差过!真是犹如一个晴天霹雳炸在了我的头顶。回到家，我就向妈妈一五一十坦白了查视力的事。妈妈原本淡红的脸转眼就变成了铁青，不过，最后妈妈看在我老实坦白的份上，还是稍稍平静了一下心情，只是比平日更严格督促我写字的姿势，叫我更加注意用眼卫生。之后的那个周末，妈妈就带我去了宁波最好的眼科医院，找了最权威的专家。经过一系列的检查，我还是无可奈何地戴上了那副让妈妈深恶痛绝的矫正眼镜。

接下来的日子里，我做作业、看书时要戴上它，平时出门还得随身携带，寸步不离;每天得滴几种药水，好几次还呛得我鼻子发酸;最让我痛心疾首的，是要远离我那心爱的电视与电脑，这简直是要把我给囚禁了!此时，我才真正体会到近视的痛苦，可除了怪我自己，还能埋怨谁呢?

很快，没有电视电脑陪伴的两个月，在我的眼皮底下悄悄地溜走了!在这段时间里，妈妈隔三差五带我去医院复查。奔波多次，终有成果。前几天，医生笑着告诉我说：“其实，你的视力还是很不错的，1.5、1.2。”听医生这么一说，我和妈妈相视一笑：我笑得得意，妈妈笑得轻松。接着，医生话锋一转，说：“不过，马上就要开学了，你一定要注意用眼卫生、注意劳逸结合、认真做好眼保健操，这样，才能真正预防近视的发生。如果眼睛一旦真正近视，那我也无计可施了。”

以前，我看到周围的“四只眼”还觉得好玩，可是有了这次戴上眼镜又摘掉眼镜的经历，我以后再也不会把妈妈的话当作耳边风了。

一定要好好保护视力，因为我能切身体会到戴上眼镜后的那份痛苦。

Today, with the development of high-technology, we can get access to all

kinds of high-tech products, such as computer, digital cameras and so on. These

products make our life more convenient, we can keep in touch with family and

friends any time any where. Our life has been changed by the high-tech, we live

in a fast-pace world. Cell phone influences our life deeply, everyone owns it.

While cell phone brings many dangers. First, cell hone contains radiation which

hurts people’s body. Today, more and more people die of cancer, the main reason

is that the high-tech products radiate their bodies, in the long run, the bodies

get sick. Cell phone is one of such products, it hurts our bodies as long we use

it. Second, cell phone distracts our attention about discovering the beauty of

life. People pay their attention on cell phone, they count on it by reading news

and making friends, being less going out. We should use cell phone properly.

What Can We Do for the Environment

our environment is becoming worse and worse，what can we do for the environment?I think each of us can do a little bit to help with this problem。

The first thing we can do is to use cloth bags instead of plastic bags when we go shopping. It helps to protect the environment. The second thing we can do is to reuse the old textbooks as possible as we can. We should also never forget to turn off the lights when we leave the classrooms in order to save energy. Whats more，it would be better if we walk or ride a bike to school. We should try our best to reduce pollution and waste。

In fact，even the simplest everyday activities can make a real difference to the environment. I believe we can make the world a better place to live in.

Sharing bike can be seen in every corner of the street, which is very

popular by the public. The foreigners speak highly of sharing bike, because they

can ride the bikes to look around the city and the expense is very cheap. As

people enjoy the convenience of these bikes, the problem comes. We can see that

many bikes have been broken and some are even put in the main road, which brings

trouble to the public. Of course when the media reported the phenomenon,

everybody condemned the negative behavior. Sharing bikes are public property,

all the people have the responsibility to protect them, so after using them, we

should just find a right place to lock them. The small act can present a

person’s nature, so dont let yourself be the rude one.

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。

With the development of information industry, there are more and more

people shopping online. Shopping online means shopping on the Internet without

going out. Therefore, on the one hand, shopping online has its advantage. One

the other hand, shopping on line also has its disadvantage.

First of all, shopping online is very convenient. People can buy thing only

they have a computer, which can surf the Internet. They don’t need to go out on

a rainy day or under the shining sun. Meanwhile, people can save their time to

finish their work or other things. On the contrary, as people just decide what

they buy depending on the picture placed by the shop owner, they can’t see the

quality before they receive the product. Sometimes people maybe buy the things

are in low quality, or some fake products.

In general, shopping online has its advantage and disadvantage. In my

opinion, I prefer shopping online than shopping on the street.

We live in nature, nature is very important to us. If we dont take care of it, the natural disaster will befall mankind.

But, because of a shortage of people environmental protection consciousness, there are some people throwing garbage everywhere, some pet, or at the side of the road. There are some busy people to go outside to eat fast food, leftovers lost carelessly. There are some people throwing paper everywhere, those paper lying on the road, just like a damage to the environment of the devil. There are some factories at the thick black smoke, the sky got dark. Some factories discharge wastewater flow into rivers, leading to the river black and stink, lots and lots of fish died. Some people are disorderly cut down trees, land became bare. Without trees, the air quality is affected, many living things disappear from lack of oxygen. There are some people in the river after eating, was thrown into the river, originally the clear river water becomes dirty and smelly ditch, passing all over your nose.

For the sake of our environment, I want to be with those people say: "please dont damage the environment, or natural disaster will befall mankind. If again so continue to destroy, the whole earth will disappear. The end of the world will always be coming.

The earth is my home, to protect the environment depends on everybody. Let us act together to protect our lovely earth!

我们生活在大自然里，大自然对我们非常重要。如果我们不爱护它，自然灾害就会降临到人类。

可是，由于人们环保意识不足，有一些人就随地扔垃圾，一些宠物就在路边随地大小便。有一些工作繁忙的人就到外面吃快餐，剩饭剩菜随手乱丢。有一些人随地扔纸团，那些躺在公路上的纸团，就像一个个破坏环境的魔鬼。还有一些工厂冒着浓浓的黑烟，把天空弄得黑乎乎的。有些工厂里排放出来的污水流进江河里，导致河水变黑、变臭，许许多多的鱼死亡。有些人就乱砍树木，土地变得裸露了。没有了树木，空气质量受到影响，许多生物因为缺氧而消失。有一些人在河边吃完东西，就往河里扔，原本清澈的河水变成了又脏又臭的水沟，路过的人都捂鼻而过。

为了我们的环境，我要跟那些人说：“请你们不要再破坏环境了，否则自然灾害就会降临到人类。如果再这样继续破坏的话，整个地球就会消失。世界末日始终会到来。

地球是我家，保护环境靠大家。让我们一起行动起来，保护我们这个美丽可爱的地球吧!

Nowadays,our world is in great danger.There are air pollution,water pollution and so on.So Its important for us to protect the invironment .We shouldnt throw rubbish everywhere.We can go to school by bike insdead of taking a bus.And we shouldnt draw on the wall.In a word,Lets protect our invrionment together.

[英语作文保护环境60字

The quality of human life has improved greatly over the past few centuries, but Earth is being harmed more and more by human activity. As we develop our technology, we demand more from our planet. Eventually, this will harm people as well.

Our planet gives us everything we need, but natural resources are not endless. Strip mining devastates whole regions, leaving bare and useless ground. Deforestation removes old growth trees that cant be replaced. Too much fishing may harm fish populations to the point where they cant recover. We are too careless in taking what we want without giving anything back.

There are more people than ever, living longer that ever. So is it any surprise that many areas suffer from too much development? Anyone living in or near a city has experienced "urban sprawl". There is a new shopping area on every corner and new houses, townhouses and apartments everywhere. Traffic gets worse and worse because planners cant keep up with growth. Keeping up with human demand is hard enough. Environmental concerns come in last.

With growth comes pollution. Companies and communities dump waste into water. Landfills are full of trash. Emissions from factories pollute the air. Barrels of industrial waste and worse, radioactive waste, have no safe place to go. If were not careful, we can harm our planet beyond repair.

People need to respect the Earth and try to preserve it. If we dont, what kind of future will we have?

Today is Dragon Boat Festival. My mother let me watch the origin of the Dragon Boat Festival from the computer. In fact, it was a memorial to Qu Yuan. Qu Yuan was a patriot. He wanted to make his country strong and often give advice to the king, but the king did not like to listen and he drove him out of the country.

Once the Qin state came to the state of Chu, the state of Chu was quickly defeated, the country was soon lost, and Qu Yuan was more sad. In the early May of this year, five, he moved a big stone and threw himself into the river. People know, very sad, in order not to let the fish eat Qu Yuan, put the dumplings inside the bamboo tube, throw it into the river, hope that the fish will not eat Qu Yuan, the dumplings are like this.

This story tells us to love our country. I also know, now eat dumplings, but is bamboo, replaced by a kind of broad leaves. Eating zongzi is also a memorial to Qu Yuan.

早晨，我背着书包走进校园。

Morning, I entered the school with a bag.

路两旁的花坛里，苍翠的青松，墨绿的冬青，在寒风中左右摇摆。

Road on both sides of the border, the green pine, green holly, in the cold wind sway.

这时，一位叔叔正要把抽完的烟蒂扔向花坛，我急忙赶过去说："叔叔，请爱护环境，不要随地乱扔烟蒂。"

At this time, an uncle was about to finish the cigarette butts into flower beds, I hurried over to say: "uncle, please take good care of the environment, do not throw cigarette butts. Tofu vegetables salted meat. Chopsticks are ready, so is the soup.

叔叔看着我不好意思地笑了，说："对不起，小朋友。"说完，他主动把烟蒂掐灭，送到垃圾箱里。

Uncle looked at me and smiled sheepishly and said: "Im sorry, kids. "Finished, he took the initiative to put out cigarette butts, sent to the dustbin.

我高兴地说："谢谢你，叔叔。"

I am happy to say: "thank you, uncle. Tofu vegetables salted meat. Chopsticks are ready, so is the soup.

叔叔也笑着夸我："你真是一个爱护环境的小卫士。"

Uncle smiled and said I: "you really are a guardian to protect the environment. Tofu vegetables salted meat. Chopsticks are ready, so is the soup.

导语：近年来,环境保护仍存在许多问题。其中最严重的问题之一是空气、水和土壤的严重污染。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!

There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.

To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.

In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.

【参考译文】

近年来,环境保护仍存在许多问题。其中最严重的问题之一是空气、水和土壤的严重污染。污染的空气对人体健康有害。污染的水导致疾病和死亡。此外,随着现代城市的快速发展,植被已大大减少。

为了保护环境,许多国家的政府做了很多。已采取立法步骤控制空气污染,保护森林和海洋资源,制止任何环境污染。因此,政府在今天的环境保护中发挥着最重要的作用。

我认为,要保护环境,政府必须采取更具体的措施。首先,它应该让人们通过教育充分认识到环境保护的重要性。第二,应该更加努力使人口规划政策付诸实践,因为更多的人意味着更多的人意味着更多的污染。最后,故意破坏环境的人应该受到严惩。我们应该让他们知道破坏环境意味着毁灭人类自己。

How to protect the environment?

Nowadays, more and more people realize it`s necessary and important to protect the environment. Also,there 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 harder,so 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.

如何保护环境?

现在，越来越多的人意识到保护环境是必要和重要的。同时，也有一些人不`不注意卫生，他们可以`停止乱扔垃圾垃圾随便或随地吐痰的时候。此外，还有一些工厂经常砍伐树木，排放的化学物质和脏水。这引起了诸如温室效应等问题。如果他们天天这样做，我们的生活会变得很困难，所以我们必须阻止他们。为了阻止他们，我们可以提出公益广告，并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。

眼睛是心灵的窗户，我们都希望有一双明亮而美丽的眼睛。工作、学习、生活都需要一双能够看得清晰的好眼睛，可是它很脆弱，特别容易受到伤害。今天，张梓涵同学给我们上了一节关于保护眼睛的实践课，使我深受启发！

张梓涵讲的非常全面，她说：“近视的原因有三种，第一种是因为环境而导致近视；第二种是因为遗传而导致近视；第三种是因为用眼不卫生而导致近视。经过分析，导致近视的主要原因是用眼不卫生。”听了她的讲解，我下定决心，以后一定要养成健康用眼的好习惯，注意用眼卫生。

张梓涵接着讲道：“我国近视的人数高达六亿人，其中人数最多的是青少年学生，近视的人数居世界第一，占全世界的百分之七十，更可怕的是小学生近视的比例占到百分之四十……”听到这里，大家的表情真可谓是丰富多彩：很多人被刚才的数字惊得目瞪口呆，有的同学高兴地庆幸自己没有近视，有的同学害怕似的低头窃窃私语……

张梓涵紧接着补充道：“现在我给大家几条保护眼睛的建议吧

1。不要在光线太强或太弱的地方看书。

2。不长时间玩电子产品。

3。读书、写字时姿势要正确。

4。要多去户外运动、多看绿色植物。

5。合理饮食，多吃蔬菜和水果，保证营养均衡。

最后，张梓涵用洪亮的声音坚定地对大家说：“同学们，让我们一起努力，爱护我们的眼睛，保护好我们的视力！”真是精彩纷呈的一节课，让我受益匪浅！

目前环保还存在着许多问题。最严重的问题就是空气、水和土壤的严重污染。那我们应该如何保护好自己的家园，保护好环境呢？以下是小编整理的英语作文环境保护，供大家参考。

In China, tea has a very long history, and has formed a Chinese tea

culture. At the same time, tea is good for our health and is loved by many

people. Chinese tea culture is broad and profound. It includes not only material

culture, but also profound spiritual civilization. Talking about Chinese tea.

Can be traced back to ancient times, it is from the Tang Dynasty and Song

Dynasty flourished.

From then on, the spirit of tea permeated the court and society, and went

deep into Chinese poetry, painting, calligraphy, religion and medicine. For

thousands of years, China has accumulated a large number of tea cultivation and

production of material culture, but also enriched the spiritual culture of

tea.

Saving Water

The world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earths surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.

However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?

We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.

节约用水

我们的世界不仅饥饿，而且因为缺水而干渴。对你来说这可能似乎奇怪：因为我们的地球表面75%由水覆盖着。但是，这巨大的数量中97%是海水、或咸水。只有剩下3%

的来自河流、湖泊、地下，和其他来源的淡水供人们饮用、使用。即使如此，这3%的水源我们也不能够完全使用，因为有些淡水是以冰山或冰河的形式存在。更糟糕的是，一些水源已遭受了污染。

然而，尽管按现状看来，这些少量的淡水即使时常转化成雨水的形式，对我们来说，也仍然够用。可是我们对水的需求却日益迅速增长。我们只有现在采取措施解决这一问

题才能避免未来世界范围内的严重水资源缺乏。限量供水会对农业和工业产生不良的影响。我们举个小小的事例就能证明水对工业的必要性。每生产一吨钢材就要消耗91，000升水，你知道吗?

我们必须杜绝对宝贵水资源的浪费。我们应该采取的第一步就是要发展水再利用的方法。该领域的实验已在进行，但是仅是小规模地进行。水资源再利用系统的重要性

对我们而言，与空间站不相上下。

With the development of economic,people now living a better life.But at the same time,many of the earths animals have already died out.

Nowdays,more and more animals lost their homes and they have no choice but to face the sorrow of missing relatives and friends.What makes it comes about?What makes their living condition even worse?The answer is human!Some people cut down plenty of trees to make fortunes,which damaged the forest and made the animals lost their home.And there are also some greedy people even hunt for animals to make money,which lead a terrible result--a number of animals are in danger.

Each anmimal especially wildlife is our friend,they play an important role in ecological balance.So,lets take action,planting trees,buliding birdhouses and so on to pretect our earth.

随着经济的发展,人们现在过着更好的生活。但与此同时,地球上的很多动物已经灭绝了。

现在,越来越多的动物失去了家园,他们别无选择,只能面对失踪亲友的悲痛。它是什么?是什么让他们的生活条件更糟糕吗?答案是人类!有些人砍伐大量的树木让财富,破坏了森林,使动物失去了他们的家园。甚至还有一些贪婪的人寻找动物赚钱,导致一个可怕的结果,许多动物都处于危险之中。

主义每个动物特别是野生动物是我们的朋友,他们在生态平衡发挥重要作用。让我们采取行动,种植树木,建筑物的鸟屋等等来保护我们的地球。
