The first day for me to go to high school, I felt so excited, because I came into the new stage of my life. The school asked the students to live in the dormitory, so I had to move out and left my parents. This was such a big challenge for me, because I never left home before. I needed to learn to be independent, what’s more, I also learned to get along with others. High school was like a little society for me and I handed the problems well. The other challenge was from study. I had to learn so many subjects and fought for my future college. I met difficulties and felt frustrated, but I told myself not to give up and I got over the difficulties. High school life is not easy, but we grow up quickly.

我上高中的第一天，感到很兴奋，因为我来到了生命的新阶段。学校要求学生住宿舍，所以我搬离了家里，离开了父母。这对于我来说是一个很大的挑战，因为我从来没有离开过家里。我需要学着去独立，而且，也要学着去和别人相处。高中就像一个小社会，我把问题处理得很好。另一个挑战来自学习。我要学习很多的科目，为了将来的大学而奋斗。我遇到了困难，感到受挫，但是我告诉自己不要放弃，克服了困难。高中生活不容易，但是我们会快速长大。

我们生活的地球正遭受着严重的空气污染。工厂排放的废气、燃烧的垃圾、汽车的尾气等都是污染大气的祸源。它们时刻侵袭着我们的呼吸道和肺，使呼吸系统的发病率逐年上升。

当空气轻微污染时，人体吸入的空气可以由鼻腔里的鼻毛除去部分灰尘，再由鼻腔里的黏液和各类支气管里的黏液将灰尘粘连住。气管和支气管内的纤毛有几千万根，它们每秒约摆动12次，像“清洁工”一样从下向上推扫呼吸道里的黏液，直至咽喉部，再通过咳嗽咳出体外。

当空气严重污染时，呼吸道的净化作用将降低，甚至完全丧失。在这种情况下，呼吸道和肺易受病菌的侵袭而患各种疾病。

由于种种原因，空气污染还在加剧。如果不能解决空气污染的问题，恐怕真有一天，人类只能带着口罩生活。

My study plan put my winter holiday is full of. I plan to put all the homework before the holiday are swept away, after the Chinese New Year in the top volume with three days to review your knowledge of our sage Confucius said, "consider"! The rest of the will to prepare book1&book 2 new knowledge, or else how can have a foothold in the superior competitive school?

“保护环境，人人有责。”不少的垃圾桶上都有这样一句话。电视和广播等媒体也都倡议要保护环境。可总有些人把这些拒绝在外，还一如既往地随地扔垃圾。有的人也许曾经看到过：一条有很多垃圾桶的马路上，还是有被风吹起的塑料袋。

我见到过一个人，边骑车边吃早饭。早饭吃完，随手一扔，塑料袋就象鸽子一样飞了出去。还有小学生：她吃好桔子，佯装把橘子皮放进口袋，却不小心掉到地上，其实她是故意的。她放进口袋之际，用手拨到了地上，假装不知道它掉了出来。这样扔垃圾的事还不少，真想不出这样能得到什么好处。

世界上有不少地区已经被“白色污染”所笼罩。白色污染其实就是白色塑料袋不腐烂，而长期不去收集，所以塑料袋越积越多形成的污染。外国是靠燃烧塑料袋来发电，而我国是将它埋在地里，对沼气进行影响。所以塑料袋并不是一无是处，但是需要统一管理，使我国不被白色污染包围。

外国曾经有一只海鸥，从高空一下子坠落沙滩。一些关于保护动物的部分人员把海鸥肚子打开，发现海鸥肚子里全是瓶盖.塑料。因为水域被影响，无鱼可吃，就只好吃瓶盖了。看过污染带来的灾害，有些人会认为，没有殃及人，还是可以继续的。千万不要这样想。有些人还在大量毁坏森林，砍伐树木。有本书上写过：要是世界上没有了一草一木，人类只能再活五百天。

因为这样，所以我们要保护环境，拒绝污染。让世界成为环保的大家族!

保护环境英语作文篇1

Through observation， I found that plastic bags on peoples harm and pollution is very large。 People often use plastic bags： mother to buy food and plastic bags； to shopping malls with plastic bags； in the restaurant to eat rice is also packaged with plastic bags to take home； even I buy stationery also with plastic bags。 People do not know what they do to the environment caused by pollution， their own body caused any harm。 Such as： people often put useless plastic bags thrown into the garbage， plastic bags in the rubbish will be smelly， so that the pollution of the air。 People also throw plastic bags anywhere， a wind， plastic bags flying in the sky， the branches also see the tree is a plastic bag， and even the river there are plastic bags。 This plastic bag in addition to pollution of the air， but also polluted our water resources。

We should raise peoples awareness， tell us the neighbors and friends and family together to beautify our environment。 On the road to see the plastic bag quickly picked up， immediately took it to the garbage disposal。 We want to start from my use less plastic bags， so that my mother every day to buy food or shopping when they first take their own bags， this is not very environmentally friendly？ Or can use their own holding things as far as possible by hand， no plastic bags。

As the saying goes： "to protect the environment， everyone is responsible" We have to protect the home environment out of a force。

通过观察，我发现塑料袋对人们的危害和污染非常大。人们还经常用塑料袋：妈妈买菜用塑料袋；去商场购物用塑料袋；在饭店里吃不完的饭也是用塑料袋打包带回家；连我买文具也用塑料袋。人们却不知道他们这样做对环境造成的污染，对他们自己的身体造成了什么危害。如：人们常把没用的塑料袋扔进垃圾堆，塑料袋在垃圾里会发臭，这样就污染了空气。人们还把塑料袋随地乱扔，一刮风，塑料袋在天空中漫天飞舞，树枝上也看到满树都是塑料袋，就连小河里也有塑料袋。这样塑料袋除了污染了空气，还污染了我们的水资源。

我们应该提高人们的认识，告诉我们身旁的邻居和亲朋好友一起来美化我们的环境。在路上见到塑料袋就连忙捡起来，马上把它拿到垃圾场处理掉。我们要从我做起少用塑料袋，让妈妈每天买菜或购物时都先拿上自己做的布袋，这样不是很环保吗？或者能用自己手拿的东西就尽量用手拿，不用塑料袋。

俗话说的好：“保护环境，人人有责”我们也要为保护家乡环境出一份力。

今天，我们一家来水泥厂调查，我们刚到酸枣村坡顶，往下一看，从水泥厂烟囱冒出滚滚浓烟，路旁的草上、花朵上、树叶上、石头上、房顶上全是一层厚厚的灰尘。

再往下走，便来到水泥厂，一股臭气扑面而来，抬头一看，到处尘土飞扬，我们赶紧捂住鼻子只往前走。

我们走了一会儿，来到一户农民家，看见一位姨妈坐在门前，我们上前问到：“姨妈你们这里现在污染大吗？水干净不干净？”姨妈说：“这里污染太大了，以前没有水泥厂的时候，水打来就可以喝，自从有了水泥厂，打来就可以喝的水，现在却变成了臭水，我们现在喝的水是从地底下抽出来的，而且还要进行高温消毒才可以喝”听到这里，我感到很惊讶，原来水泥厂的污染有这么严重。

走了一会儿，我们看见一位老奶，我上前问到：“奶奶，你们桌子一天多少遍？庄稼长得怎样？”老奶奶皱着眉头说：“桌子一天要五六遍，庄稼长得也不好，你们看我家地里的豆苗，像被开水烫过一样，全部都枯萎了，还有我们这里的桔子树，以前长得很茂盛，桔子又大又甜，现在桔子树也全枯萎了，即使有几棵存活下来的，结的桔子又小又苦。我们也多次向上级反映，但不了了之”老奶说完，深深的叹了口气。

听了她们的活，我的心里非常难受，我多么希望这些工厂在生产的过程中，能将排出来的废气和灰尘进行处理，让老百姓有一个更好的生存空间，那该多好呀！

Should students make friends on line? Some people say yes. The Internet

helps make many friends. Chatting on line, students can express their feelings

and opinions more freely, and even get help with their foreign language

studies.

Others, however, think students should not. They say making friends on line

is a waste of time, which should be spent more meaningfully on study. Besides,

some students, get cheated on line.

It is my opinion that students should place their study, health and safety

before other, things. As for friendship, we can readily find it in our

classmates and other people around us.

The summer holiday is coming. Our class have had a discussion about what to do during the holiday. Some are in favor of staying at home. They think its both convenient and comfortable. Whats more, they can save money for other purposes. But they will lose the chance of getting to know the outside world.

However, others prefer to go out for traveling since it can increase their knowledge and broaden their horizons. But they will spend more money and meet some difficulties while traveling.

In my opinion, it would be much better to stay at home, for I can do what I like, such as reading books, watching TV, and helping my parents with the housework.

one day on my way home from school, i saw an old woman standing by the roadside①, with a heavy bag on her back. she seemed very worried. i went up to ask her what the matter was. the granny② told me that she had just come from the countryside to see her son, who worked in the steel works. as she had never been here before, she did not know the way to the factory. so i took her there. there was really a lot of difficulty in finding her son＇s place. the granny and her son were very thankful to me.

i got home very late, tired and hungry, but i felt happy, for i had done a good deed for the people.

Some fish are forced to leave polluted water and are flying in the sky. But unfortunately, air is also so polluted that they have to wear masks. Each of them is crying, “Where is my home?” What a terrible sight!

Mankind has brought so much pollution. Waste is being poured into rivers and seas. Poisons to kill pests in farming and chemicals go into rivers and seas, too. Poisonous gasses from factories also make the air so dirty. The whole balance of nature is being destroyed as a result of our ignorance of the environmental protection.

Personally, man can not live alone on the earth. Should fish die from serious pollution, so would man! It is high time we did something to prevent such a scene from happening.

Nowadays, pets become so close and friendly to our human-beings that more

and more people enjoy keeping them. Pets can bring them a lot of joys and

happiness, because playing with pets is a good way to communicate with the

nature. Besides, pets can comfort old people who live alone. With the companion

of pets, they won’t feel lonely. Nevertheless, I’m not interested in keeping

pets at all. For one thing, keeping pets is bad for environmental protection,

since pets usually make a lot of noise and contaminate the roads. For another,

the virus carried by pets may cause fatal disease. What’s more, sometimes pets

may attack people when they are unhappy. Consequently, we had better not keep

too many pets, so as to ensure our health and security. Besides, those pet

lovers must take some effective measures to prevent their pets from hurting

people and polluting our environment.

Dear editor,

I’m writing to tell you about the discussion we have had about whether an entrance fee should be charged for parks. 60% of us schoolmates think that an entrance fee do not meet people’s expectations, for a park is considered to be a place where the public can have a good time when they are not busy either at home or at work. If an entrance fee must be paid by the visitors for a park, it will be necessary to build a gate and surrounding walls. In the end a city will take on a bad look. 40% of us schoolmates think that an entrance fee can be accepted, but it must not be too expensive. The money from ticket selling can be used for paying the gardeners in the park and buying some other kinds of flowers and trees.

With regard to myself, I think an entrance fee is useful, for it can be used to protect a park. Do we share the same opinion, dear editor?

Yours truly,

以前的我虽然有保护环境的觉悟，却总是没有行动，吃完的食品袋，随手就扔;看完的广告纸，我还要撕碎了才扔。后来，我看见起风时满天乱飞的食品袋、纸片、灰尘不禁思考起来。

在我很小的时侯，曾听爷爷讲过一个故事：从前，有座山庄，那里森林葱郁，河水清澈，鸟语花香，人们过得幸福快乐。后来，来了一个人对当地的人们说：“你们拥有巨大的财富。”人们高兴极了，以为这儿埋着大量的金银财宝。于是，他们开始砍倒树木寻找黄金。几年后，那人又来了，人们因为没有找到财宝而质问那人。那人叹口气说：“我说的财富就是你们原来拥有的那优美宜人的环境呀!”人们听后难过极了，由于人们的肆意破坏，现在就连鸟儿也很少光顾了。

当时，我并没有听懂这个故事。我也不认为村民们破坏了世外桃源般的环境是不对的，反而责怪那外来者，如果不是他的一句话，人们不会那样做。现在想想，美丽的大自然，是人们无穷的财富，这应是人人都可以意识到的，外来者只不过是提醒村民村要好好珍惜它罢了。

爸爸告诉我，在他小的时候，门前那条小河是他们的乐园。清清的河水从村子的中央流过。河里有很多小鱼、螃蟹和蚌，你只要站在岸边就可以看见河里的一切。爸爸和他的小伙伴就在这条河里游泳、玩耍。每次下河玩耍回来，手里还拿着“战利品”。河面上没有杂草，那时运送粮食的轮船可以自由地进出

古往今来，地球妈妈用甘甜乳汁哺育各族儿女，让我们茁壮成长!用健美臂膀挽起高山大海，让我们健康成长。可是现在人们为了自身的利益将她折磨得天昏地暗。现在我们的地球妈妈面临着巨大的环境危机，所以我们要一起来帮她解决难题，一起来保护环境。

With the improvement of our living standard， more and more people can afford a car. As a result，our roads are more often than not crammed with cars.

However，with more and more waste gas being discharged by the cars，the problem of air pollution bees even more serious. So nowadays we advocate to lead a low-carbon life.

My suggestion is we should ride bikes more often instead of driving cars.By riding a bike， we can not only exercise our body but also protect our environment.

Why not have a try， my dear friends?

与我们的生活水平的提高，越来越多的人都买得起汽车的。因此，道路往往没有堆满了汽车。然而，随着越来越多的废气排放是汽车、空气污染问题变得更加严重。所以此刻我们提倡过低碳的生活。

我的推荐是我们就应更经常骑自行车而不是开车骑一辆自行车，我们不仅仅能锻炼身体，也能保护我们的环境。为什么不试试，我亲爱的朋友?

Because of the fiction movie 2012 which describes a horrible scene that the whole world was destroyed by earthquake, volcano and tsunami, the view of doomsday is making a great clamor. Mayans predicted December 21, 2012 is the end of the world and the sun of 22th will never rise again.

Though it is now seems that this prediction is just a nonsense without any scientific support, it did provoke peoples thinking about environment. In awake of the prediction, we cant help asking why this horrible prediction happen? I think one answer may be related to the environmental degradation. As we all can see and feel, the worlds environment is going downhill with severely polluted rivers and airs. More often we cant see clearly the sun because of heavy air suspended matter caused by pollution. If continues going this way, I think the doomed day will come true if not now, then one day.

In consequences, for the sake of our own life, we should take efforts to protect the environment and save this planet. is the alarm bell to human beings that we should protect our planet, culture and civilization. Otherwise, the doomsday will come soon.

Since I go to high school, I live in the school and stay away from my parents. I have three roommates, at the beginning, we have trouble in staying in the same room, but now we have got used to it.

One of my roommates impresses me so much, since she comes to our room, she keeps the habit of reading the novel when we go to bed. She told me that when she lived with her parents, she dared not to read it because her mother would blame her for sleeping late. Now she is very happy that she is out of control, it seems that she is free.

But I feel sorry for her, because she is short-sighted now, what’s more, she is lagging behind other students in the study. Staying away from her parents, she is not strong enough to behave herself. We should have the strong will and behave ourselves.

自从我上了高中，我就住在学校，远离父母。我有3个室友，刚开始，我们不习惯同处一室，但是如今，我们已经习惯了。有一个室友让我印象很深刻，自从她住进我们的房间，她就在我们睡觉的时候保持看小说的习惯。她告诉我们在她和父母住在一起的时候，她不敢看小说，因为她妈妈会责怪她那么晚睡觉。如今她很高兴再也不受控制了，似乎她得到了自由。但是我为她感到遗憾，因为她现在已经近视，而且，在学习方面也落后于其他同学。离开了父母，她不够强大，无法自律。我们应该有坚强的意志，并且自律。

Last Sunday my father and I went fishing along a river. We found the water so dirty that we could hardly catch fish in it.

A lot of factories along the river always poured their waste water and rubbish straight into the river which made the river water polluted. In this way most of the fish in the river were killed.

If the river water all over the country is polluted like this， no living things will exist in the water. As we all know， environmental pollution does great harm to living things and human beings. Now more and more people have come to realize how serious this problem is. Our government is doing her best to take measures to fight against pollution. We expect that the water in every river will be made cleaner and cleaner before long.

上个星期日我和爸爸一起去钓鱼。我们发现水太脏了，我们几乎不能在它的鱼。

沿着这条河的许多工厂总是把废水和垃圾倒进河里，使河水受到污染。这样，河里的大部分鱼都被杀死了。

如果这个国家的河水都被污染了，水里就不存在生物。我们都知道，环境污染对生物和人类都有很大的危害。现在越来越多的人开始意识到这个问题有多严重。我国政府正在尽最大努力采取措施打击污染。我们期望在每一条河流中的水将在长时间内变得更清洁，更清洁。

Marine lives in fish and all kinds of chemical substances,is very important for human.But many people like throwgarbage into the sea,the sea will pollution.Cause fishdeath,water depletion.We should keep our environment,to protect the beautiful sea.

海洋里生存着鱼和各种化学物质,对人类很重要.但是许多人类喜欢向海里投垃圾,海水就会污染.导致鱼儿死亡,海水枯竭.我们应该保持环境,一起保护美丽的大海.

Everyone can do something for our environment. For me, I should try to save electricity in my daily life. For example, if I am the last person leave the classroom in the evening, I will always remember to turn off the lights. In order to protect our forests, I will use paper wisely. I should try to use both sides of paper whenever it is possible. I will not use things like paper cups and disposable chopsticks because they are made of wood. I believe that doing all these small things will improve our environment and help make our world a better place to live in.

“与善人居，如入芝兰之室，久而不闻其香；与恶人居，如入鲍鱼之肆，久而不闻其臭”，自丛读了《小偷和他的母亲》这则寓言，才让我真正明白了这其中的道理。

《小偷和他的母亲》这则寓言主要讲的是：一个小男孩小时候偷了同学的写字板，他的母亲不但没有教育小男孩，反而还夸奖了小男孩。后来小男孩长大，胆子也越来越大了，到处偷金拿银，盗窃、抢劫无恶不作。有一次，他正在偷窃别人的物品时，被当场抓获，因作恶多端，被判为死刑。行刑前，他很想再见母亲最后一面，和母亲最后说几句话，白发母亲来了，当他母亲刚把耳朵贴在儿子嘴边，就被他很狠地咬了下来……

这则寓言告诉我们一个道理:长辈对孩子的教育是很重要的， 泥土和玫瑰相处，吸收玫瑰的芬芳，久而久之，就会有相同的味道，也能够为别人带来了香味。正如人也一样，和一群善良的人在一起玩，必会养出善良的心灵，和一群品质恶劣的人在一起，不邪恶也难。 可见不良的环境能改变人的习性。

俗话说:“近朱者赤，近墨者黑”。“莫以善小而不为，莫以恶小而为之”。作为父母，要敢于承认自己的缺点和不足，以身作则，去感染孩子，为孩子树立好榜样，让他们在没有污染的环境下茁壮成长。
