Protection of the Environment

Once man did not have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be unlimited.

Today things are different. The world has become too crowded. We are using up our natural resources,and polluting our environment with dangerous chemicals. If we continue to do this, human life on earth will not survive.

We realize that if too many fish are taken from the sea, there will soon be none left. Yet,with modern fishing methods, more and more fish are caught.We know that if too many trees are cut down, forests will disappear. Yet, we continue to use powerful machines to cut down more and more trees. We see that if rivers are polluted with waste products, we will die. Yet, waste products are

still put into rivers.

We know that if the population continues to rise at the present rate, in a few years, there wont be enough food.What can we do to solve these problems?

If we eat more vegetables and less meat, there will be more food available. Land for crops feeds five times more people than land where animals are kept.

Our natural resources will last longer if we learn to recycie them.

The world population will not rise so quickly if people use modern methods of birth control.

Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future.

[保护环境的英语作文精选

春风送暖，柳树的枝条随风飘动，绿茵茵的，草地上开着各种各样的花朵，五颜六色的，红的、黄的、紫的……连成了一片花的世界。小河的水清澈见底，小鱼儿在水里欢快地游来游去，相互嬉戏。小鸟在树枝上梳理自己的羽毛，偶尔还会有几只白色的大鸟从远处飞来，一眨眼就贴着水面往远处飞走了，只有柳枝还在摇晃。

见此美景，我不禁回想起前几年此地的环境：土黄色的小河水混沌不清，水中一条鱼都没有，水面上漂浮着一堆堆的垃圾，散发着一阵阵的臭气。

这几年随着人们环境保护意识的逐渐增强，小河边的不合格工厂都不见了，于是鱼儿也随着河水的干净逐渐回来了。

还记得以前的正月初一凌晨是没法睡觉的，鞭炮响彻夜空，空气中全是火药味。今年全家睡了个好觉。

现在汽车还是很多，排放的尾气还在继续污染环境。我希望未来的汽车变成了太阳能启动的汽车，没有空气污染。

保护环境，人人有责。我们要从自己做起，不乱扔垃圾，不放烟花，少开私家车。

我国的城市河流和湖泊污染情况是非常严重的,城市河流水有不同程度的富营养化问题。以下是小编给大家整理的形势与政策论文：城市水环境的问题探讨的内容，欢迎大家查看。

摘要: 随着经济快速发展，城市生态形势压力也与日俱增，水环境问题已成为制约社会发展的大问题，环保基础设施建设严重落后，城市生活污染物未得到有效控制，工业污染源未得到严格治理，农业污染日益突出，部分河段水质受污染严重，河水发黑发臭，完全失去水质功能。本文主要对城市水环境治理及污染防治对策进行了分析探讨。

关键词：城市规划;水环境质量;污染防治;对策

城市生态环境是城市宜居水平评价和城市经济发展的重要因素。作为城市生态环境的重要组成部分，城市水环境对生态环境的治理和改善有着重要的影响。受传统经济发展理念的影响，我国城市水环境污染情况不容乐观。而且在城市扩建过程中还造成了大量周边湿地的消失，造成了城市生态环境、水环境的进一步恶化。针对这样的情况，我国近年来加大了城市生态环境治理力度。从城市规划与发展的角度出发，恢复城市周边湿地环境、改善城市水环境与生态环境。

一、城市水环境的基本特点

1、城市用水的特点

生活用水和生产用水是城市用水的主要类型，由于城市人员密集、工业化生产程度高，所以，城市用水需要较高的质量、较大的供水量、稳定的供给，这对城市采水、供水和用水来说有着不同于农村的特点。

2、城市用水的依赖性强

城市由于用水量大、供水要求高，所以，单纯依靠城市区域的供给和开采往往难于满足城市发展的需要，因此，大众城市往往需要从城区周边或外地调水来满足城市的用水需要，“引滦入津”、“南水北调”就是这样的举措。

3、城市水环境脆弱

在我国北方，城市生活和生产用水大都在简单处理或未经处理就直接排放到环境之中，在日积月累的大量污染的影响下，城市水环境受到了严重破坏，并且这一现象有蔓延和恶化的趋势，造成水环境的脆弱和生态的破坏，影响城市深入地发展。

4、城市地下水环境恶化

城市地下水环境恶化来源有两个，一是，城市生产和生活中大量污染源渗入地下，造成对地下水资源和水环境的破坏;二是，城市地表硬化导致城市地面下渗量的减少，在大量开采地下水的同时，没有必要的补充，出现水环境的恶化。

二、城市水环境综合治理方法

1、以人为本，科学发展

把维护广大人民群众的根本利益作为第一点，把群众最关心、最直接和现实的水环境保护问题为重点，转变发展观念，重视生态文明建设，加快建设资源节约和环境友好社会，走科学发展道路。

2、优先保护饮用水源

合格的安全饮用水源是人民生活的必需品，水环境治理应突出重点，优先保护饮用水源，确保群众饮水安全。

3、强化节能减排、效益原则

与区县减排工作挂钩，把COD削减量考核指标纳入到区县水环境治理目标体系中，明确各区县污水处理率、污水处理厂运行负荷率等量化指标。切实保障三个达标，即污水处理率必须达标、污水处理厂的运行负荷率必须达标、COD的减排必须达标。合理安排资金，对节能减排效果明显，有一定经济基础，技术条件成熟，符合国家和行业产业政策的项目优先考虑。

4、治本方针

突出截污治污。河道沿线村镇、企业密集，污染来源复杂。为此，河道治理将坚持“先截污、后清淤、先治理、后换水”的原则，周密排查河道沿线污染来源，大力实施清淤、截污、生态护坡、河岸绿化等措施，加强河道水体自净和生态修复功能;在突出截污治理的同时，各区县还将坚持污水处理厂、配套管网同步建设，大力提升现有污水处理厂运行负荷率，妥善解决污水出路，切实提高河道水环境质量。

5、加强协作，落实责任

市水务局于去年成立了河道水环境考核办公室，将清水工程已治理河道纳入考核范围，各区县按照属地管理原则在本辖区内建立水环境管理机构和相关管理机制，有效巩固水环境治理成果。此外，目前市政府已正式批准本市河道水环境实施“河长制”管理意见，即将公布全市主要河道“河长”名单，构建完善的河道水环境管理长效机制，为今后本市水环境由加强治理向强化管理转变打好基础。

三、城市河流水防治和改善技术的应用

1、底泥疏浚和河床微生态系统修复

在河流洪水、蓄洪功能上,底泥疏浚主要体现在河流利用水面变化增加行洪、蓄洪能力。作为沉积物沉积,有的湖泊水的深度可以被调整,从而减少其调节和存储功能。增加城市河湖疏浚河道水容量后,以确保顺利排出这些河流洪水,保障人民群众的生命和财产安全,也避免了洪涝灾害。底泥疏浚是水环境综合整治的一项重要措施,滇池、巢湖、太湖等水环境综合整治已被广泛使用。可见,合理的疏浚清除污染物,对于生态系统的恢复和重建具有非常重要的作用。

2、人工增氧技术

人工增氧技术是基于城市河流水污染后缺氧的现象,人工的向水体中注入空气或氧气,从而加速水体复氧的进程,提高水体的溶解氧水平,恢复和提高在水中好氧微生物的活力,使河流水的污染物净化,从而改善河流的水质。河流氧气一般使用固定和移动站充氧平台两种形式。河道人工增氧技术的应用,能够使得水质不同时期达到消除黑臭、减少水体污染负荷、促进河流生态系统恢复的目的。

3、调水引流水质改善技术

贯穿城市的内河河网水系,因为控制结构的限制,使得河流水不能够连接到外部的水体,造成水处于静止的状态,当天气炎热的时候,溶解在水中的氧气浓度就会降低,容易导致水质变坏。通过改进水域水动力条件,提高水体污染物的稀释能力,增强局部水体的自净能力,许多城市在水资源利用和部署中,通过跨流域调水工程,解决空间分布不均的问题。

4、植物修复技术

对于河道河流自然恢复应采取生态化措施,主要是通过恢复河岸植被、恢复天然湿地,在河岸种植芦苇、浮萍、睡莲、水生植物和其他湿地植物,以提高水体的净化能力。种植水生植物的城市河流水,一方面能够通过植物的根系的吸收,从而降低和遏制富营养化趋势;另一方面通过种植水生植物,可以也起到美化水体环境,提高城市的景观的效果。

5、生物净化技术

生物净化技术是充分利用天然水体自净的功能,采用人工措施,创造更有利的环境有利于微生物的生长和繁殖,并培养出大量的微生物从而增强水体净化能力,以提高纳污水体氧化降解有机物能力的一种净化方法。目前国内外最常用的生物净化技术是曝气技术、生物膜技术与投菌技术。生物净化技术,其成本低,对环境的影响小,能够有效降解污染物,是水体污染处理的最佳选择之一。生物净化技术及产品的开发,特别是分解菌株的培养也将被筛选到河流水污染控制技术之中,是未来城市水污染防治和治理的发展趋势。将具有特殊分解能力的菌种添加到河边,能够将水体中有毒有害物质分解为无毒无害的物质,从而加速有毒物质的分解、转化,不仅可以提高河流的净化能力,而且也实现了河流的生态修复。生物产品的运用将成为人工增氧、底泥疏浚等现有防治技术的有益补充。

四、结束语

综上所述，我国的城市河流和湖泊污染情况是非常严重的,城市河流水有不同程度的富营养化问题。目前,在城市河流污染环境下,需要完善城市管线网络,并建设污水处理厂,具体的水污染防治技术措施有:底泥疏浚、人工增加氧气、引水排水水质改善、植物修复、湿地水净化技术等河流强化净化技术。能够应对不同的城市的污水状况,使得城市河流水污染的情况得到了有效的控制,促进城市河流的健康发展。

Take good care of the environment is everyones responsibility, everyone has the duty to care for the environment. The cries of the earth, is made by human; The formation of natural disasters and human themselves. We cant let such things happen again, because of this our home will face disappear.

With the continuous destruction of forest, make the air fresh, no longer in life make people breathing "not smooth". So, we should protect trees, protect the nature. Let our the earth mother to restore the original appearance.

You every good care environment of small action, will be your memories. Bent down to pick up a piece of waste paper, a word to stop people damage the environment. Will be a thing of the past.

We now do dribs and drabs, not just for the sake of our own, also is a important foundation for our future generations. Let them no longer face the disaster, let they no longer lose family. Take good care of the environment, starts from me!

爱护环境是每个人的职责，每个人有爱护环境的责任。地球的哭泣，是人类所为;自然灾害的形成，也是人类自己造成的。我们不能再让这样的事再发生，因为这样我们的家园即将面临消失。

随着森林的不断毁灭，使生活中的空气不再新鲜，使人们的呼吸“不再顺畅”。所以，我们应该保护树木，保护大自然。让我们的地球妈妈恢复原来的模样。

你每一个爱护环境的小举动，都将成为你美好的回忆。弯下腰捡起一片废纸、一句话阻止人们破坏环境。都将成为历史。

我们现在做的点点滴滴，不仅仅是为了我们自己，也是为我们的子孙后代打下重要的基础。让他们不再面临灾难，让他们不再失去家人。爱护环境，从我做起!

自从改革开放以来，不仅城市在急速变化，家乡的小乡村也发生了翻天覆地的变化。今年春节回到家乡，与爸爸爷爷所说的样子不太一样，与照片上灰色的一片也不一样，把改革前的昨天与辉煌的今天相比，家乡的变化深深烙印在我心里。

家乡在韶关的一个小村子里。

翻开那已经没有封面的相册，里面已经微微发黄，还有点点黑斑的，颜色只有黑白灰三种的照片。相册的几页都不翼而飞了，但细看照片还是被收藏的很好。就是这样一本老旧发黄的相册里，记录的确是着几十年来所发生的变化。

几十年前，全村没有一条平坦、宽阔的水泥路，全是泥泞的泥巴路。每到下雨时，人们总得小心翼翼的过泥泞路，而且泥泞里又小窄，十分不便。现在村里的泥泞路都铺上了干净又舒适的水泥路，不再是坑坑洼洼的。

几十年前，几个村子连一台小小的收音机都没有几台，更别说一台电视机。现在村里每家每户都有一台电视机。村里就是一个大家庭，信息传递的速度也快。再也不会相以前一样，信息根本进不来。

几十年前，全村没有摩托车，大都是自行车。从村里到县城要步行1小时左右。现在村里家家都有摩托车，一半的人家都买了汽车，汽车只要5分钟就能到县城了。

几十年前，村民建的房子材料都是土，房顶是瓦片，窗户只是一层薄薄的塑料，所有的家具材料都是木头，是名副其实的“土房子”。当冬天来临时，屋外寒风呼啸，就算屋里生起柴火，冷的打颤。现在每家每户都建起了水泥房，在墙壁还贴上了各种各样的瓷砖，非常宽敞，装修豪华，就像小别墅一样。

不仅村里的环境发生了巨大的变化，连村民的收入也提高了，村民懂得了如何种植，懂得科学种植，所以收成自然就高了。

家乡的变化可真不小!

我相信，几年后再看看村子，肯定还是一幅多姿多彩的画卷!

In fact, there are many things that can seriously pollute the environment: litter, spitting, grass and so on. The consequences are severe. But the waste of resources cannot be ignored. The worst is the waste of water.

At present, the reform and development of our country is at a critical juncture, and we should strive to achieve the goal of building a moderately prosperous society in all respects. But there are still some problems -- our living environment is seriously polluted; And the green resources are falling.

We do a lot of what the environment, such as: on one occasion, in a clean small garden, there have been some rubbish, gradually where there are a lot of people throw garbage, there is a garbage dump. It turned out that the trees were green and the flowers and grass were blooming. The bees and the butterflies were there, and there was a smell of enchantment. But now, there was nothing to do with it, and the smell of it was so bad that no one was willing to stay there any longer. Alas! It is a pity that such a beautiful garden is gone. If people notice that they dont pollute the environment, now, by the way, its a kind of escape. And, what a wonderful thing for people to have a rest and take advantage of the cold. But now its a junkyard, and the consequences of polluting the environment are terrible.

And there are a lot of factory waste is also pollute the environment, but the most serious is the pollution of water, I heard of such a story: there was a village, there was a clear pool. There were lotus flowers in the water and the goldfish, and it was so beautiful that visitors to the village would not forget to take a look at the scene. And people in the village wash and cook and drink water and water, so the water is very precious. One day, a businessman opened a factory near the pond, and the factory shut down a lot of waste water and garbage and went into the pond... The result can be imagined: the goldfish died, the water side became the sewage, the tourists no longer came, the people in the village moved away... Alas! The little pond has disappeared. The factory severely polluted the environment and made the environment in the village very bad and affected peoples lives. Its a story, but there are a lot of these things in everyday life, and the results are very serious, not just simple consequences.

In fact, there are many things that can seriously pollute the environment: litter, spitting, grass and so on. The consequences are severe. But the waste of resources cannot be ignored. The worst is the waste of water.

Now, Beijing is a city of severe water shortages, but there are a lot of people in the waste water, such as: there are a lot of people out of the water to wash the dishes and laundry water and reuse. In fact, although can only save a little water, economy is a lot of!

Also, people who sell fish in the market love to put a faucet on the side of the water, and when they use water, they will let the water flow freely. How much water they would waste if they went on like this!

The drink, the wine, etc., are now made with water. Some factories use a lot of water, so some of the water is wasted. Thats a lot of wasted water. This water can do a lot if you save it! You can also avoid a little water.

[保护环境的英语作文模板

我的家乡在绵阳市三台县北坝镇龙潭村三队，听村里的长辈说，这里的人以前不讲公德，不爱卫生，不勤洗手，随地乱扔果皮纸屑，乱倒垃圾，乱伐树木，往小溪里扔农药瓶，杂草、和塑料袋，以前，小溪是家乡的人们用来洗衣服的地方，溪水清澈透明。但现在却被污染得变成青黑色的了，随手在水面一捞，不是死鱼、杂草，就是塑料袋。手上的鱼腥味很难洗掉。有时在深水处用手一捞，既不是死鱼，也不是杂草和塑料袋，而是被沙子埋在水底的臭石头和死螃蟹。

不懂得环境保护的人们是把小溪变成脏沟的元凶。由于人们乱砍乱伐，山上茂盛的树林变成了一排排树桩和倒下的枯树。河边的树也不知去向，泥沙没有了归所，就一点一点往溪里流，最终把小溪给埋了。环保意识淡薄的人们不懂得这个道理，仍置法网于不顾，把树林砍倒了一片又一片，连非常隐蔽的山洞也也漏了出来，树上的鸟窝也全军覆没。

现在，环境比以前好多了，家家户户住的房子都从土房变成了砖房，再也不用担心下雨房屋会漏水，地震房屋会倒塌这类情况的发生。从前没有垃圾池，现在倒垃圾方便多了，人们口中都是赞美的言辞，再也听不到肮脏的话语。在这样美好的环境中，大家渐渐养成了爱清洁、讲卫生、护环境的好习惯了，家乡的小溪也一天比一天明静。我爱家乡的美丽的环境，更爱家乡致力于环境保护的人们。

Today, as the development of the technology, people live a much better life than before, the average wage is promoted highly. The economy develops at the cost of polluting the environment, we can see the pollution everywhere, like the river water is dirty, the situation is so serious that we must take some action to control the environmental pollution. First, we should not throw away the rubbish, whenever we have rubbish at hand, we should keep the habit to throw it into the dustbin, sometimes the garbage can be recycled. Second, the government should make some measure to punish the industry which is not deal with the pollution well. With the government’s intervention, the businessmen will pay special attention to the pollution and dare not to ignore it. Protecting the environment needs everyone’s effort, to ourselves and our offspring’s health, we must take action to protect the environment.

Now, our side of the car constant more up, the environment also increasingly worse!

For example, we can go to school by bike or walk, it can exercise.

If you have time can use less elevator, many climb stairs. We can not only physical exercise, but also to protect our environment.

现在，我们身边的汽车不断的多了起来，环境也越来越糟糕!以至于我们周围的空气有很多有害物质。所以，我们要苏身边的小事做起。比如，我们可以骑自行车上学或者步行，这样还可以锻炼身体。有时间的话可以少用电梯，多爬楼梯。我们不仅能锻炼身体,也能保护我们的环境。

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.

一转眼十年过去了，家乡变了，环境变得十分好，街道一尘不染，也引进了高科技。每天都有机器人分解垃圾、净化水资源。街道旁边种满了绿树，大地绿树成荫，像个绿色的无污染的清新世界。人类驯服了青蛙，它让害虫无处可逃;家乡四周的绿树，它让空气更加清新。人们过着无忧无虑的生活。

十年前可不是这样的。道路上的地面十分泥泞，一不小心就会滑倒，比冰面还滑。那时人们贪图方便，把垃圾随手丢进小溪、路边，长年累月小溪被污染，臭气熏天，人们都绕道而行。山上也光秃秃的，因为人们大量砍伐树木，有的树木随着柴烟中消失了，有的被用来盖房子，有的被用来取火，间接污染了空气。很多人也因此得了疾病，那时的家乡，是那么的糟糕啊!

现在好了，我一定会好好珍惜现在的环境。

From this cartoon, we can see that at the top end of the river,is a chemical factory and a paperrnaking factory which send out and poisonous wastes. And the river has been seriously polluted,n be seen from the color of it. Along this "black" river, there area few people selling fresh water which must have been taken from far away places.

At the first glance, it is very strange to us how can people sell water along the river, but this is the case, because the water in this river is undrinkable. This presents a serious social problem--environmental pollution. With the development of economy, our living standards have been greatly improved. But we can＇ t ignore the fact the air we take in and the water we drink today are not as fresh and clean as they used to be. Some kinds of pollution can even be deadly to people. It is high time that we took some measures to solve the problem.

I think we can first call people＇s attention to this problem so that they will be aware of the serious consequences of it. Then,we can pass certain laws to restrain the factories from sending out wastes. Finally, we can do more resarch work to find out ways to deal with the wastes.

Keep Square Clean, Tidy On Sunday, still on display on Tian＇anmen Square were dozens of floats that were paraded along Chang＇ an Avenue during the NationalDay celebrations. Thousands of people strolled on the narrow lanes be- tween the floats that fragmented the square, busily taking photos. Not far from the noisy crowds, yellow leaves fell nonchalantly from locust trees along the driveway, sending out the first signals of the coming autumn. But even if all the leaves fall, they still cannot cover the brown and black spots on the hitish stones in the huge square.

Such stains of chewing gum, stale oil or some worse blemish have remained a constant pain for city cleaners since the square ＇was re-opened a few months ago after renovations to celebrate the 50th anniversary of the founding of the People＇s Republic of China.

Few renovation project planners likely foresee this discouraging outcome. Originally, they merely intended to give the city a facelift. The square was indeed impeccable when new: The-white terrazzo surface not only looks clean but it was made with materials that help prevent it from becoming slippery.

However, as time goes by, the virtue becomes the vice: the surface attracts and accentuates dirt. As a result, China＇ s most high profile site has to suffer the indignity of being paraded daily efore thepublic in a humiliation state.

While the tourists who litter should bear the bulk of the blame, the renovation designers should also have learned something: including the square＇s sanitary maintenance issue into their consideration.

我们渴望干净的地球，渴望健康的地球，渴望环保的家园，渴望绿色，健康，卫生的社区……让我们用爱心去关注环境的变化，用热情去传播环保的观念，用行动肩负起环保的重任。从我做起，从现在做起，从身边的点滴小事做起，把环保承诺变为实际行动。

We desire to clean the earth, to earth for environmental health, home, eager to green, health, the health of the community...... Let us love to pay close attention to changes in the environment, with enthusiasm to spread the idea of environmental protection, with action to shoulder the responsibility of environmental protection. Begin from me, start from now, start from the side of the little things, the environmental commitments into actions.

记住，保护地球，就是保护我们自己。

Remember, the protection of the earth, is to protect ourselves.

人人都有家乡，人人的家乡环境各有不同，现在让我说一说我家乡的环境吧!我门家乡原来的环境是比现在好的，原来，人人都保护环境。山比现在的绿。天比现在的蓝，虽然原来的生活比较穷，但人们不知道砍伐树木，不知道伤害小动物。而现在的人只会砍伐树木，只会伤害小动物。还有原来我小时候的时候，夏天我还和朋友一起去游泳而现在呢?他们挖沙挖的都看不见底，更别说是游泳了。还有自从人类进入科技世界，环境更是别提了，到处都是朔料袋等各种各样的垃圾。由于地上太多垃圾所以天空就没有原来的蓝了。还有许多场子排许多污水，污水旁边的小草，树木还有小花等植物都枯萎了。现在的人们不知道保护环境，但有一些人知道保护环境，但是还不够，我们大家都应该保护环境，那样我们的世界就更美丽了。

枝江，我的家乡，你已历尽无数个春秋，你已历尽世态炎凉。现在的你与以前的你有着天壤之别。你正一步一步走向繁荣。

五十年前，你面容憔悴，百废待兴。听我爷爷讲，那时正在粮食过渡，爷爷还说他们队里有三十几个人，结果饿死了十几个人，当爷爷讲起这些事，心里不由感慨万分。听着爷爷的讲述，我想道：现在的我们吃饭都会剩一点，还总抱怨这不好吃那不好吃。爷爷他们那时吃树皮、花生壳都过得好好的，令我无比震撼的还有他们那时罕有的零食，竟然是—饭团！从爷爷的口中，我还知道了他们小时候都是玩的“天然玩具”—捡猪草，放牛……在他们紧张的学习中，还掺杂了许多家务。

再说说那时的房子吧！每个都是土坯房，哪有现在的高楼大厦，哪有现在楼房美丽的外观。你能想象当宽阔的公路变成窄窄的田埂子吗？当然，在以前，没有宽阔的马路，没有照明的路灯，更没有人行道。那田梗子的两边是田地。晚上，走在这田梗子上，能不使人毛骨悚然吗？没有马路，那就更没有红绿灯了。不过，那时候，虽然没有红绿灯，但那时的车祸数量可大大减少了。

做为新一代的我们，生活在如此美丽的生活环境里，该是多大的荣幸呀！我一定要勤奋学习，为你增光。

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 becomes 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.所以现在我们提倡过低碳的生活.

我的建议是我们应该更经常骑自行车而不是开车骑一辆自行车,我们不仅能锻炼身体,也能保护我们的环境.为什么不试试,我亲爱的朋友?

今天晚上，我迷迷糊糊地睡着了，梦见了十年后的家乡。我看见了郁郁葱葱的森林;看见了清澈见底的湖水;看见了湛蓝的天空，空气清新甜润;看见了一条条宽阔的马路。

我来了马路上，看见人们有的坐着太阳能汽车，这种车排放的尾气不会污染空气，如果雨天的话，它只要充足电充足电就可以了;有的骑着变速自行车，可以方便调速;还有的坐着超能摩托车，不用自己骑，你说去哪里，它就会载着去哪里。以前，人们的车开得非常慢，容易造成交通堵塞，可现在就不同了。人们在宽阔的马路上，开着节能环保车。

接着，我又来到了公园里，小鸟在树上婉转地歌唱，好像是为美丽的家园而感到自豪。许多的蝴蝶展开着五颜六色的翅膀，在草丛中飞来飞去，美丽极了!许多小蜜蜂在花丛中采蜜。池中的荷花盛开着，有红的，有白的，有黄的……非常鲜艳。

最后我还来到了果园里，果园里的水果都非常新鲜：有苹果、草莓、梨……在果树上都张开了笑脸好像在叫人们快来摘呢!农民伯伯让机器人帮忙摘果子呢!。

我忽然不知被谁推了一把，我睁开眼睛，原来是一个美丽的梦。可我相信，只要保护好环境，我们的家乡就会变得更加美丽!
