保护环境的高一英语作文（实用20篇）

我想有个"家"，小鸟在树上呼唤着，我想有个"家"。鲸鱼、海龟、鲤鱼也同样在呼唤着，我想有个"家"。大树花草也在呼唤着，我想有个"家"，大象、老虎以及人类也是一样，在呼唤着，我想有个"家"。

21世纪，所有生命面临的最大敌人就是环境的污染。环境是大自然赐给我们最宝贵的财富，我们应该珍惜它，爱护它，保护它。植物是大自然的屏障，一棵树一天能吸收大量的二氧化碳和很多的有害气体，还能提供人们生活必需品，如纸张，家具等。我们要懂得节约，节约用纸，就会有更多的树木免遭砍伐，它们每天能为人类吸收很多有害气体，也能释放很多的氧气。但是，有许多人不懂得这个道理，乱砍滥伐，铺张浪费。致使大地裸露，风沙肆虐，大水冲毁了农田、家园，多少人流离失所，人类为自己的愚昧付出了惨痛的代价。我们再也不能让这些可怕的事情发生了。人类，清醒清醒吧，保护大自然要从现在开始了!

我从网上获悉，臭氧层，被称为大地的保护伞，因为它可以挡住大部分的紫外线，如果没有臭氧层，天地将会全部被烤焦，所有生命将会化为灰烬。破坏臭氧的元凶就是工厂有害气体和车辆的尾气，大量含氟空调、冰箱的使用等等，所以我们要尽量少用空调，低碳出行节约用电，平常能骑电动车就最好不开车，能骑自行车就尽量不骑电动车，这样可以减少电力的浪费和尾气的排放，还能锻炼我们的身体!

水是生命之源，尤其是淡水。据报道，全球70%是盐水不可饮用，淡水紧缺。所以我们要节约用水关紧水龙头，不污染我们的江河湖泊，不乱丢垃圾和排放有害物质，给鱼儿们一个干净的家，给我们一个干净的生命之源。

我还知道很多小动物正在灭绝和被捕杀，他们有的被端上人类的餐桌，有的被制成工艺品供人类观赏。听妈妈说2003年的非典，就是因为人们吃了野生动物，将野生动物身上的病毒带到了人类世界。还有今年的新冠病毒，据说是也是捕杀食用野生动物造成的。没有买卖就没有杀害，我倡议：从现在开始，从我做起，不吃野生动物，并阻止捕猎者捕杀动物，给动物们一个安心的家。

保护环境不能再挂在嘴边，大家要用我们的行动保护我们这个美丽而又脆弱的地球，保护我们共同的家!

Protecting the Environment

In the last several decades, our earth has been extremely polluted, such as air pollution, water pollution, noise pollution and so on. In recent years, the extreme weather becomes more and more frequent. Winter gets colder and summer becomes hotter and it rains more frequently. All of these warn us that protecting the environment is a serious and emergent event. As our general people, we should build proper lifestyle. We should pay attention to water and light saving. When we go out, we should firstly choose the public transportation. The most important is that we must realize that we can do a lot of things to protect our environment. Its our duty to make our home better. Let’s change from ourselves.

在过去的几十年里，我们的地球已经极度污染，比如大气污染，水污染以及噪音污染等等。近几年，极地气候越来越频繁。冬天越来越暖，夏天越来越热，还经常下雨。所有的这些都警示我们保护环境是一件严肃紧迫的事。作为普通老百姓，我们应该形成合适的生活方式。我们应该注意节约水电。出门的时候我们应该首选公共交通。最重要的是我们必须意识到我们可以做很多事情来保护我们的环境。使我们的家园变得更美好是我们的责任。让我们从自己开始改变。

[初中英语作文及翻译：保护环境

世界原本是美丽的，而被人类污染的世界是丑陋的，世界上有的河水是绿色的，里面有很多垃圾，而且非常臭呢！世界上有些地方的大路和小路上都是垃圾，一开车就踩到没吃完的食物和没喝完的饮料，把牛奶盒压出牛奶味，会招惹苍蝇，还会变得很臭、很恶心。

世界很大，也就代表垃圾也很多。扔在地上的香蕉皮会让人摔跤，草地上的大树也成为受害者，吃完就随手一扔，很容易扔到大树。大树会很容易发臭，有蚂蚁爬来爬去，严重的还会枯萎。

爱护环境有个小故事。有天早上，我在校园的操场上看见一个男孩子，吃完了零食就随手把包装袋扔在了地上。我赶紧跑上去，说：“你这样做不对。会破坏校园环境。”我还叫他把垃圾扔在垃圾箱里。小男孩看我一眼，就立刻跑开了。我弯下腰拾起包装袋放进了垃圾箱。老师表扬了我，我很高兴呢！

其实我觉得环保不光是大人的事，也是我们小学生应尽的责任和义务。其实，绿化家园，保护生态，不是一件遥不可及的壮举。环保，从自己做起！行动，从身边的一点一滴的小事做起！

如今中国飞黄腾达，在当今的情况下，也有一些重要的问题需要我们去解决，比如目前最严峻的问题便是环境问题。

它威胁着人们的生存和发展，大规模的垦荒时很多土地变成了沙漠。乱扔垃圾，导致白色塑料随处可见，肆意砍伐，很多动物失去了原本的家园。

以下，我提几个建议。

第一，不乱扔垃圾，垃圾分类回收，看见地上有纸巾，便随手捡起。

第二不乱砍伐树木。不使用一次性用品，购物时尽量使用布包减少白色污染。

第三，不浪费水资源。洗澡的水可以拿去冲花，冲厕所，让每一堆水都有用可循。

第四，设立一些动物保护的节日。保护珍稀动物，让他们不在地球上消失。

这些或许不是我们个人可以做到的，但是只要我们大力宣传，总会有人注意到这些。因此需要每个人付出一点点，这个世界就会有所改变。

滴水穿石，非一日之功。环境的破坏，也不是短期内形成的，而是经过长期的积累导致的，所以，保护环境也是我们应该打的一场持久战，没有捷径可循。

所以希望我们每一个人都能够好好遵守。

Dear David，

I am afraid that you will think me unpardonably negligent in not having

answered your letter dated 7, December sooner, but when I have told you the

reason, I trust you will be convinced that the neglect was excusable. When your

letter arrived, I was just in Hong Kong. As my family could not forward it to me

during my absence, it has been, therefore, lying on my desk until the moment

when I took it up. Now the first thing I have to hasten to do is to write to you

these few lines to express my deep regret.

I enjoyed many pleasant sights during my trip. I shall be pleased to give

you an account to of them when I see you next.

Sincerely yours,

Tom

As we all know, the environment around us is getting worse and worse more and more seriously today. Water is polluted, we have no clean water to drink. Many trees are cutting down, some animals are getting less and less. Some factories are pouring dirty air into the sky. The population is increasing faster and faster, resources are getting less and less…etc. Not only does it affect our lives and health, it also has a great affection in the future. People’s health has been greatly affected by air, noise and water pollution. Many people died of diseases. In order to live a better life, something must be done to stop the pollution. It’s our duty to protect our environment. We shouldn’t throw away rubbish everywhere. Trees are very helpful and important for us. We should plant more and more trees in order to live better and more healthy in the future.

If everyone makes contribution to protecting the environment, the world will become much more beautiful. In a word, if everyone pays more attention to our environment, there will be less pollution and our life will be better. “There is only one earth”, I hope everyone will protect our environment well.

First of all, let me tell you a true event. That is my grandpa with me by boat from yichang to three gorges occurs when one thing.

We all got up that morning, the people on board, is preparing to play water to wash shu. But the faucet for half a day on the boat were down only a few drops of water, one asked, originally is the boat ran out of water! So, we only have stood in long lines, slowly, etc. Although I looked at the ship, the ship under a stream of water, but no one would like to use it. Because the water is so dirty, so HunHuang, who dare to use? Line only slowly, slowly, etc!

Although in the high-speed development of science and technology nowadays, but the impact on our environment. Reduced river pollution, air pollution, the trees, the increasing of the desert... All this is all thanks to the human! Countries while in value, although the world in value, environmental protection, what and how much these things figure up attention? In my opinion, is rare. Although countries in so to speak, but whats the use of words and not of deeds? Did just a few, too! Dont grab from main reason! You see, the Yellow River water is not still contaminated? So the factory does not still pollute the atmosphere? Should grasp, starts from the quality of people, quality grab, but the country and the world to do so? No! Just like to do even when you are done. In the polluted environment is not so?

Animals are extinct, flash floods in explosion, dust storms still exist... It fully shows the environmental pollution! Countries will only go to disaster relief, instead of simply grabbed, will only go to disaster relief, whats the use? Dont all kinds of disaster is still in? We should like lu xun. He had become a is in order to save the Chinese, and he found that it will not solve the fundamental, so he became a writer, to save the people of the spirit. Because this is the fundamental! So, we as the master of the 21st century, you should understand, what is the root of the damage to the environment, from the point to solve it. Work hard -- the 21st century we!

首先，我先给大家讲一个真实的事件。那是我随我的外公从宜昌坐船前往三峡时发生的一件事。

那天早晨，船上的人都起来了，正准备打水洗淑。可是船上的水龙头半天也只下来几滴水，一询问，原来是船上的水用完了!所以，大家只有排着长长的队伍，慢慢的等。我望着船下，船下虽然有着流不尽的江水，但却没有一个人愿意来使用它。因为江水太脏了，是那么的浑黄，又有谁敢去使用呢?只有慢慢的排队，慢慢的等!

如今科技虽然在高速发展，但这影响到了我们的环境。河流污染，大气污染，树木的减少，沙漠的增多……这一切的一切都是拜人类所赐!国家虽然在重视，世界虽然在重视，什么环境保护日，这些事又有多少人影起了注意呢?在我看来，是极少的。国家虽然在这么说，可是光说不做又有什么用呢?做了也只是少数罢了!根本没有从主要原因抓起!你看，黄河的水不是还在被污染吗?工厂不照样还在污染大气吗?抓，就应该从小抓起，从人们的素质，品质抓起，可是国家乃至世界这么做了吗?没有!即使做了也只是做样子罢了。环境不是照样还在被污染吗?

动物还在灭绝，山洪还在爆发，沙尘暴照样存在……这都充分说明了环境还在污染!国家只会去赈灾，而不去根本抓起，只会去赈灾，这又有什么用呢?各种灾难不还是照样在发生吗?我们应该像鲁迅一样。他当初从医是为了拯救中国人，而他发现，这解决不了根本，所以，他当了作家，去拯救人们的精神。因为这就是根本!所以，我们作为21世纪的小主人，就应该明白，什么是破坏环境的根本，从要点去解决它。努力吧――21世纪的我们!

环境保护

Nowadays, peoples life has changed a lot with the development of modern technology and economy, which has put lots of negative effects on the environment.

Why this? Because, firstly, some factories are pouring wastes into rivers, lakes, seas and so forth; secondly, because of human activities, a great number of plants and animals are losing their lives; thirdly, using modern machines and chemicals is bad for the environment. Besides these, there are a lot of human activities which have done or are doing harm to our surroundings.

For this, I think, first, our government should make drastic measures to regulate human activities; second, we human beings should take pains-taking work to stop ourselves destroying the environment and try our best to protect our living space more.

[英语作文：环境保护

Looking ahead, and some are just a bump on the ground, large tracts of forest were cut down, into peoples lives in the wood products. It is only for their own interests, many animal it to become destitute and homeless. This is not a false illusion, this is the bloody facts.

Once upon a time, a large number of animals and plants in the world were destroyed, and many animals and plants are on the verge of extinction, which is why? This is because the man casually trees, destroy the ecological environment, this is the fundamental reason.

Land resource is one of the three major geological resources (mineral resources, water resources, land resources), is the most basic human production activities and labor objects. Human utilization of land reflects the development of human civilization, but also caused the direct destruction of land resources, which is mainly manifested as unreasonable cultivation caused by soil erosion, land desertification, land salinization of soil and soil pollution and so on, and the soil and water loss is particularly serious, today the world is facing a serious crisis. According to estimates, soil loss of the cultivated land is about 230 tons / year.

Some people think acid rain is a silent crisis, and in the history of the impact our most serious threat to the environment, is a look at the enemy. This is not alarmist. With the increase in industrialization and energy consumption, acid emissions are also increasing, they enter the air, after a series of role in the formation of acid rain.

The sun summoned the planet in the solar system to open an emergency meeting, the theme is to save the planet. The sun to see everyone to the Qi, and clear the clear voice, said: "The stars, our good sister earth has been at stake, the doctor said that her blood is toxins, the body of nutrients is also depleted, in this way "The moon says," In recent years, mankind has mined a lot of oil, minerals, wood and other materials, without protecting the environment, and the earths sister is not sick. "Saturn says" Way, we save the earth together! "" Well! "The stars have promised.

After the stars go back, have heard of human beings looking for a second home, so have made an appointment, never the second home of mankind, have also thrown away the conditions may be human use. For example: the moon threw away the oxygen, Saturn threw away the appropriate temperature, Mercury thrown away ... ... Finally, the human consciousness that the earth is the only human home, carried out to protect the Earth action.

300 years later, the sun also held a meeting, the earth also participated, she looks beautiful, green skin, clean blood, more importantly, she becomes healthy, the moon said: "sister, see you now So happy, I am happy for you.

Friends, the mother of the mothers disease though good, but also need to continue convalescence, and now, let us work together to the earth dressed as the most beautiful planet in the universe.

保护环境英语作文篇3

There are many diseases that are harmful to human health and even threaten human life. Human into the 21st century, the world has occurred in the number of amazing changes. In the people for the rapid development of science and technology, but also experienced a better anxiety and even disaster. In addition to the panic of the development of high-tech, especially biotechnology, war and disease seem to bring mankind directly to the door of hell.

Water pollution on the human body harm, the body in the process of metabolism, with drinking water and food, the water of various elements through the digestive tract into the various parts of the body. When the lack of water in some of the human life process necessary elements, will affect human health. For example, in some areas of water iodine deficiency, long-term consumption of this water, it will lead to "big neck disease", is the medicine called "endemic goiter." When the water contains harmful substances, the greater harm to the human body. Carcinogenic substances can be consumed by eating contaminated food (food, vegetables, fish, etc.), into the human body, but also through the water into the human body. According to the survey, drinking contaminated water, suffering from liver cancer and gastric cancer and other cancer incidence, than drinking clean water is about 61,5% higher. When the sewage contains mercury, cadmium and other elements into rivers and lakes, the aquatic plants put mercury, cadmium and other elements to absorb and enrich them, fish eat aquatic plants, and in its body to further enrichment, people eat poisonous Fish, mercury, cadmium and other elements in the human body enrichment, so that the human body and death. In this way, from the aquatic plants → aquatic small animals → small fish → big fish → the body, forming a food chain. The body eventually became mercury, cadmium and other elements of the "foothold."

Water pollution hazards to aquatic organisms Water lives in a variety of aquatic animals and plants. Biological and water, between biological and biological complex material and energy exchange, from the number to maintain a dynamic balance. But under the influence of human activities, this balance has been destroyed. Some of the beneficial aquatic organisms are poisoned when humans release pollutants into the water, and some of the stained aquatic organisms will multiply, consume a lot of oxygen dissolved in the water, so that the beneficial aquatic life is forced to relocate due to hypoxia Or death. In particular, some toxic elements, both difficult to dissolve in water and easy accumulation in the body, causing great harm to humans. Such as mercury in the water content is very low, but the content of aquatic organisms is very high, the content in the fish is also surprisingly high. Assuming that the concentration of mercury in the water body is 1, the concentration of mercury in the aquatic organisms is about 700, and the concentration of mercury in the fish is as high as 860. Thus, when the water is contaminated, on the one hand led to biological and water, biological and biological balance between the damage, on the other hand some of the toxic substances continue to transfer and enrichment, and ultimately endanger human health and life.

地球是我们人类共同的母亲。这个和蔼可亲的生命的摇篮,是多么的艳丽缤纷，是多么的七彩阳光；是啊，潺潺的黄河是祖国的血脉在流动；是啊，滚滚的长江是中国伟大的历史见证……而现在，地球已身经千灾百难，身上已千仓百孔。因此，环境保护已刻不容缓。环境保护要从我做起；环境保护要从身边的一点点、一滴滴做起；环境保护要从身边的小事做起；一滴水，能换来一片生机；一度电能换来一次温饱；一粒粮，能换来一份收获；一棵树，能换来一米阳光。所以我们要珍惜每一粒粮、每一滴水、每一度电、每一张纸……

珍惜资源，保护地球，人人有责。同学们，地球上的资源是有限的。如煤、天然气等资源都要经过几百年，甚至几亿年的积累才能形成的。而自私的人类却为了自己的利益而去大肆开采不可再生的能源。正如《只有一个地球》中一文说到：“矿物资源不是上帝的恩赐，而是经过几亿年的地质变化才形成的。地球是无私的，它慷慨地向人类提供矿产资源。但是，因为人类的不节制开采，现在地球上的矿产资源已经快消失殆尽”。因此，珍惜资源已刻不容缓；珍稀资源保护地球，刻不容缓。

水是生命之源，更是万物之本。而人们常常会认为水是取之不竭，用之不尽的，在这里我要认认真真地告诉你们这一观点明显是错误的。目前，世界上已有百分之八十的国家缺水，我国已有32个城市严重缺水。我还听说过一个更荒唐的新闻。新闻上说：“西方国家一级严重缺水，而有人却看到了一个商机——去卖水，那个人花费大量金币，把南方的水运倒西方国家去卖。”你不要看地球表面有那么多蓝色，但其实水只有总数的三分之一。因此，保护水资源已刻不容缓。

环境保护，人人有责；环境保护，刻不容缓。环境保护必须从我们身边的点点滴滴做起。只有人人都懂得环境保护，我们的天才会更蓝，山才会更绿，水才会更清。

动物，本身就和我们人类是同等级的生物，我们只是不过拥有了智慧罢了。但是现在有许多人还在残忍地杀害野生动物。所以我呼吁大家保护动物，也正如有一句话所说的：“枪响之下，没有赢家;没有买卖，就没有杀害。”

保护动物，首先就是要减少、制约那些偷猎者等坏人。我们国家需要不断完善相关法律，加大执法和打击的力度，切实有效的打击罪犯。同时，我们也要减少购买用野生动物制作的工艺品、服饰等非必要的物品。也许你可能在想，一个小小的象牙工艺品，我花了很多钱，也没有关系。但是，只是一个象牙，那么就要杀掉一头成年象，也许在你看来没什么，但是对于象来说，它需要生存多久，躲避那些天敌，才能有这个象牙。所以，保护动物，也要从身边自身做起。

此外，保护了动物，我们就保护了生物多样性，让它继续长存，这也同时间接地保护了我们人类自身。在生物学里，生物多样性是一个很重要的部分，在生物圈里，也就是地球表面发挥着巨大无比地作用。物种越多，这个生物圈里，这个系统也就更加稳定，难以被破坏，或者说拥有了很强的自愈能力。所以，我们地球上的生物越多，我们生态环境也就更加稳定。但是没有了动物等生物，那么我们将会受到自然地惩罚，也终将走向灭亡。

动物，是我们的好朋友，也许你认为老虎狮子等很凶，但是他们也都是为了自保，也只有这样，他们才能更好地生存。此时我，我也相信你已经认识到保护动物的重要性了吧。所以，最后，让我们一起来保护动物吧，一起呼吁，让我们的生态维持稳定，保护动物，保护生态，就是保护我们人类自己。

随着科技的发展，人们的生活不断地改善，地球也有着日新月异的变化……但是人们却忽略了一个问题——环境保护。

地球妈妈每天都呼吸着难闻的气味，这都是工厂排放出来的“毒烟”，她的皮肤都慢慢地裂开了，“头发”也慢慢地掉光了……她曾经是那么年轻漂亮，那么活力充沛。如今，她变得千疮百孔，不像以前那样快乐，因为人们砍伐树木，动物们都无家可归，它们非常伤心。没有了树木，地面就会变得干燥，还会造成水土流失。树木可以吸收二氧化碳释放氧气，有利于我们的生活。现在人们为了赚钱而不顾保护环境，工厂乱排放污水、废气，污水排放到小河里，使活泼可爱的小鱼不能在清澈见底的小河生存。

我们应该节约用水，洗完手后拧紧水龙头，不要浪费一滴水，那么你们想想一个人浪费一滴水，全国有13亿人就白白浪费了13亿滴水，这些水积蓄在一起，已经可以形成一片汪洋啦！你们又何曾想过，当你们开着电脑不关机，开着电灯不关等的时候……会浪费多少电呢？我们要时刻提醒自己“节约用电”。可以把洗脸水拿去浇花，洗衣服的水用来拖地、擦窗户。

人们！醒醒吧！让我们共同保护环境，地球妈妈，请相信我们，我们一定会想出更多的方法保护环境。在不久的将来，您的孩子会穿上绿袍。恢复您原来美丽的样子，因为只有您的健康、美丽，才有我们温馨的生活。

I am a student in Huaxing Middle School. Do you know the plastic bags? Do you often use the plastic bags? I don’t like them. I think they use the wasting valuable oil their production. And they can’t decompose(分解) in a short time. The plastic bags will make our world worse. I agree with the rule, which people can’t get the free plastic bags in the shops, supermarkets. It encourages people to use their cloth bags and baskets. It’s good for our environment.

So I hope all the students in our class stop to use the plastic bags, and use our own cloth bags. I hope we can take care of our environment.

Let’s make our world more and more beautiful.

Last week, I visited the geological museum with my best friend, Liu Bing.

It was my first time to go there. The moment we arrived there, we found that the

building was grand. When we walked into it, there was a big hall in front of us.

And then there were several rooms to show different kinds objects. There was a

room for collecting scripts and paintings. There was another room to store

clothes and shoes in the old times. The next room was for collecting the daily

necessities in the old days. In a word, all the things in it had a long history.

I learnt some knowledge from it.

Recently I found out that some bad things happened in our school.

At ordinary times is very neat and clean campus, has recently become some dirty, some corner or in the corridors, students can be seen the plastic bags used to hold things, eat some fruit peel, cabinet and throw away the packing bag of after loud snacks. Is each class in our school there is a certain region responsible for cleaning, clean, will arrange the students per class every day the rubbish is certainly in the classmate after cleaning the health, and others left, I think the quality of the students really is very low, I dont know to cherish other peoples work achievement, dont know how to protect the campus environment.

Students, not to be good, not to be, not to be evil small but to be, everybody join hands together, protect our campus environment together!

最近我发现我们的学校发生了一些不好的现象。

平时十分整洁干净的校园，最近却变的有些脏兮兮的，一些角落里或者是走廊里，都能看到同学们用来装事物的塑料袋，还有一些水果皮、碎纸屑和吃完小零食以后扔掉的包装袋。我们学校是每个班都有一定的卫生打扫的负责区域的，每天每班都会安排学生打扫，这些垃圾肯定都是在同学打扫完卫生之后，又有人丢下的，我觉得这些同学的素质真的很低，都不知道珍惜别人的劳动成果，不知道保护校园的环境。

同学们，不以善小而不为，不以恶小而为之，大家携起手来，共同保护我们的校园环境吧!

Environment is a basic human existence conditions, if we destroy the environment, it is ruined our survival conditions.

At present, the ecological environment is becoming more and more bad, is the greatest influence on our water resources. According to the relevant information reported: the laying of drainage system and detergent used to grow, consume the oxygen in the water, fish died, deterioration of ecosystem. Human activities can make a lot of industrial and agricultural pollutants into the water, the water is polluted. The world each year about 4200 sewage into the river, polluting the 5. 5 trillion of fresh water.

This is how the startling fact, protect the environment is everyone duty, why want to destroy?

Lies a small river near my grandmas home, on the bottom, before my sister and brother in ones childhood often swimming in the river, and their friends to play in the water, uncles and aunts are often in the river to wash clothes, wash dishes, and now, near the river built a chemical plant, the production of waste water discharge into the river, originally the bottom stream gradually turned into a black sending out the smell of the river. The adults never go to the river to wash clothes to wash the dishes, friends never go to the river to play, too!

How I miss the crystal-clear stream! I think: cherish resources, good care environment, these are GongZaiDangDai, force and art event! If we are in such polluted water, that we can use water resources will be less and less, we destroy the environment, is destroying our living conditions.

Let us join hands to jointly protect the environment, dont let water into water, protect the environment, is our common responsibility!

环境是一个人类生存最基本的条件，如果我们破坏了环境，这等于破坏了我们生存的条件。

目前，生态环境日益恶劣，对我们影响最大的就是水资源。据有关资料报道：排水系统的铺设和清洁剂的使用有增无减，消耗水中的氧，使鱼类死亡，生态系统恶化。人类的活动会使大量的工业、农业污染物排入水中，使水受到污染。全世界每年约有4200多亿的污水排入河中，污染了5。5万亿的淡水。

这是多么让人触目惊心的事实啊，保护环境是人人有责的，为什么要破坏呢?

我外婆家附近有一条小河，以前清澈见底，我的姐姐、哥哥小时候常常在小河里游泳，和他们的小伙伴们在水中嬉戏，叔叔、阿姨们也常常在这小河中洗衣服、洗菜，而如今，小河旁建造了一个化工厂，把生产的废水排放到河里，原本那清澈见底的小河渐渐变成了黑黑的散发着怪味的小河。大人们再也不去小河洗衣服洗菜了，小伙伴们也再也不去河里嬉戏!

我多么怀念那条清澈见底的小河啊!我想：珍惜资源，爱护环境，这些都是功在当代、力及千秋的大事啊!如果我们在这样污染水，那我们可以用的水资源就会越来越少，我们破坏环境，就是破坏我们生存的条件。

让我们携起手来，共同保护环境，不要让淡水变成污水，保护环境，是我们共同的责任!

Dear Charlie,

I’m LiHua, president of the Student Union. I’m writing to invite you to our Dragon Boat Festival celebration, which is to be held in the Lecture Hall at 14:00 next Monday.

The Duanwu or Dragon Boat Festival, generally celebrated on the fifth month of the Chinese lunar calender, falls on June 18 this year. It is one of the oldest festivals in China, with a history of more than 2,000 years. Legend holds that this festival is in memory of Qu Yuan, a patriotic poet during the Warring States Period.

In the celebration, you can enjoy a performance about that legend and watch live broadcast of dragon boat racing. In the meanwhile, varieties of Zongzi, an essential food for this unique occasion, are available, which take different shapes and various fillings. Come and join us!

Your early reply is highlyappreciated!

Yours,

Li Hua

Today the quality of our natural environment has become an

important issue. The world population is rising so quickly that the world has become too crowded. We are using up our natural resources and at the same time polluting our environment with dangerous chemicals. If we continue to do this, life on earth cannot survive.

Concerned people have made some progress in environmental protection. Governments of many countries have established laws to protect the air, forests and sea resources and to stop environmental pollution.

Still more measures should be taken to solve environmental problems. People should be further educated to recognize the

importance of the problems, to use modern methods of birth control, to conserve(保存） our natural resources and recycle（再循环） our products. We are sure that we can have a better and cleaner place in the future.

现在的人们乱砍伐树木、破坏环境、捕杀稀有动物……一切都是为了利益，我不禁想到了一个问题：人类的未来还有救吗？

人们乱砍伐树木，还在浪费纸张。一次性筷子的.数量不断增加，而树木不断减少。这让我想起了三年级下学期学的一篇课文：《一个小村庄的故事》，课文里的人们乱砍树木，得到了大自然的惩罚。下了五天五夜的雨，到了第六天黎明雨停了，但小村庄却被洪水卷走了。不知这是不是人类将来？

原来清清的水也被旁边的工厂排出的污水和烟污染的浑浊不清。我第一次到妈妈老家时，旁边的小河里到处是垃圾，成了苍蝇的地盘，蚊子的天地。听妈妈说在她小时候都可以在小河里摸鱼，可现在连一点干净的地方都没有了。不知地球妈妈的血液——水还有清澈的吗？

森林里的稀有动物越来越少了，野生的白虎已经灭绝了，只有人工繁殖的白虎。国家一级保护动物兼国宝的大熊猫也濒临灭绝。最常见的东北虎也变得非常稀少。野马目前也灭绝了。这都是人类捕杀动物的后果。

我们必须保护环境，因为我们包括地球上的所有生命都不愿生活在被污染的地球上，我们喜欢生活在干净、美丽又祥和地球上，所以大家一起动手，把地球回复成以前的样子，让地球上的生灵们和平共处，共创美好的家园！

保护动物

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。

这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，大家都十分喜欢它们。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，就就应爱护它们。”他的脸红了，并且回答说他不会再那么做了。
