Dear John,

Im glad to hear from you. Now let me tell you something about our city. Nantong is trying to set up a national civilized city. We middle school students are also doing some things for it. We are all polite to our teachers. (In class, we listen careful to them./When we meet them, we always say hello to them./…)We also respect the old. For example, we help them cross the streets.

We are always ready to help each other.(When one has difficulty with his studies, others will help him at once./...)We often show our love to those in trouble. Last month, the students of my class donated money to the earthquake-hit areas.

Besides, we plant trees to protect the environment and make our city more beautiful.

Nantong is my hometown. I will do my best to turn Nantong into a civilized city.

Zhang Tong

[中考英语作文预测：周围的环境

不是我跟不上时代的步伐，是时代的变化太快，当我还在回想老家那泥泞的小路和低矮的小房时，老家却用它那巨大的变化向我说：你OUT了，咋们都换新面目了。

十一放假这几天，我又来到老家，上一次来老家还是寒假时来的。这一次与上次可大不一样，去老家的路再不是泥泞而又狭窄的小土路，在这几个月的时间里，大部分土路都被改建成了一条条宽敞而又平整的水泥路。一路上，许许多多人家都在使用收割机收割稻谷，听见收割机隆隆的声音，我不禁回想起小时候看爷爷奶奶收割稻谷的样子，每一穗稻谷都是他们用镰刀一刀一刀割下来的，与现在相比，“累人式”的日子再也看不到了。

到了老家，已经是黄昏时分，爷爷奶奶已坐在堂屋歇息，见到我们来了，好像非常激动，“你们以后可要常来呀！现在和以前不同，水泥路马上就能修到家门口了，现在呀，生活水平提高了，咱们准备盖一座新房，以后就不用再住这个小房子了。孙儿，赶明个我带你出去走走，让你看看咱们这儿的新变化……”爷爷好像有一肚子说不完的话。我抬头看了看爷爷、奶奶，发现爷爷奶奶好像也和以前不同。对了，是他们身上的衣服！以前爷爷奶奶身上穿的是薄布衫，到了冬天一点也不能保暖；现在他们身上改穿褂子了！到了冬天还可以穿上厚厚的棉袄和皮袄。

我们随爷爷奶奶进了屋，爷爷奶奶去准备饭菜了。我们就坐在堂屋看电视。不一会儿，丰盛的晚餐就端上来了。“哈哈，现在农村生活水平提高了，我们吃的饭菜也比以前好了！”爷爷笑着说。我一看饭桌，果然是爷爷说的那样，饭菜比以往丰盛了许多，鸡呀，鱼呀什么的，很多食物……

第二天，我和爷爷顺着新修的水泥路向前走，走着走着，我发现在田那边的空地上多了两个人工挖掘的大坑，我不解的问：“挖两个坑干嘛呢？”“你还不知道吧！现在咱们不仅只种田了，这里准备建一个专门养鱼的养殖场，这样每年才有更好的收成。”我们继续往前走，走了一会遇到了赵叔，赵叔正推着装着木头和红砖的手推车，见了我，赵叔立刻绽开了笑脸：“呦！这不是小曹吗？几个月不见，咋长这么高了呀！”“赵叔，你弄这东西干嘛去呀？”“咱家养的鸡越来越多了，鸡没有地方住了，我正准备去给鸡盖房子呢！”说着，便吹着口哨走远了。

家乡变了，人也变了，但不变的是向往未来的精神。从泥泞的土路到宽敞的大路；从低矮的小屋到敞亮的大房；从曾经的贫穷到现在的富强。给人留下的是一片美好的回忆……

My hometown mulan, in towns the low-profile, flowing is the biggest tributary of heilongjiang, songhua river.

Morning breeze is blowing, microwave float. Clouds of light on the water with water. The shore, sending out the scent of the grass shore willow branches are swaying gently. Vaguely saw the outline of the mountain, river, continuous mountains were like this microwave, let a person feel is gentle and kind, like a mothers letters, also does not say to tire. The sides of the river is full of green. Grass, leaves, and the river of life is green, they are in the start of the day is full of green hope.

The sun is shining, the songhua river water. River billowing east go, is to seize the legendary treasure? Wash the sound of water, the branches swaying and laughing voices of people constitute a jolly, light travel route. Sunshine is aspersed spread evenly on the river, river sparkling, seems like a big moving mirror, reflecting the dazzling light.

Into the night, the sun sets to the west, on the river and the gold of the horizon. Deep blue sky, a bright moon hanging in the round, each star like a sparkling gem with the sky. The moon reflected on the river, also is so round, like the river on the also have a moon. In the quiet of the night, the songhua river is also gradually fell asleep, ended its journey of a day.

The beauty of a gentle, songhua river is wild, it is quiet...

“小城故事多，充满喜和乐，欢迎你到小城来呀！收获特别多……”每当听到这首歌《小城故事》我就会想起我的家乡五莲。

我们五莲虽是一个小县城，但是有两座美丽的山，九仙山和五莲山，九仙山有一个美丽的龙潭大峡谷，那里的水很清，清的可以看见潭底的沙石和鱼儿。它还是江北最大的杜鹃园，每到五月至六月，杜鹃、迎春花等许多漂亮的花儿就会竞相开放。山上到处是红颜色、黄颜色，深的、浅的、明的、暗的、红的似火、黄的如画，再加上翠绿的叶子，那恐怕只有画家才能描绘出来；五莲山有水帘烟雨，那晶莹的水帘明明亮亮的，薄薄的，像精心纺织出来的绸缎。温度变化出来的薄雾飘浮在半空中，真应了“水帘烟雨”这个名字，因为有帘有“烟”有“雨”，这不是给人以美的启迪，美的享受。这些自然美景，真是如诗如画，令游客神往、陶醉。

五莲城内，人们住宅也建造得很有特色，一座座楼房拔地而起，错落有致。也许受到水清水秀有影响，人们都比较喜欢养些美丽的小花，每一条街道都栽上了芙蓉树，每到夏天，整个县城就变成了花的海洋，空气中到弥漫着芙蓉花的香味。

我们五莲不但环境优美，人们的生活更美。小城的商店一家挨着一家，繁华热闹。柜台上摆满了琳琅满目的商品。家庭影院、手机早已走进了家家户户，不少家庭还添置了电脑、数码摄像机等等。日子过得就像芝麻开花——节节高，我相信五莲的明天会更加美好壮丽。

我爱我的家乡，现在我要好好学习，成为国家有用之才，把家乡建设的更加美丽富饶！

我的家乡在湖北的一个村庄，这里景色优美。

听奶奶说，很早以前的家乡空气清新，天空湛蓝深远，树木葱葱茏茏。村前，池塘的水清澈见底，清得能看到水底的小石头。一阵阵微风吹来，小波纹一圈一圈的荡漾开来，小鱼在水里快活地游来游去。

可现在，我的家乡变化可大了。天空不在那么蓝了，灰蒙蒙的；山上的树木被人们一棵一棵的砍下来，小山变成了光秃秃的土地，在这里建起了一栋栋的房屋，树木做成了各式各样的家具。池塘的水也干枯了，小石头露了出头，小鱼也失去了它温暖的家。

看着家乡的这些变化，我们要行动起来，不要乱砍滥伐树木，爱护花草，爱护小动物。在池溏不要乱丢垃圾，不要捞小蝌蚪。减少使用一次性物品，向人们宣传环保的重要性。

让我们从现在做起，从每一件小事做起，保护环境，保护我们美丽的家园。

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.

Low-carbon life means a kind of lifestyle in which people do their best to reduce energy consumption and carbon dioxide emissions.

Then，how can we live a lowcarbon life?Firstly，we should recognize that the lowcarbon life is not only a kind of lifestyle but also a life attitude.Each of us is responsible for the greenhouse gases in our daily actions.To combat climate change we have to take the combined efforts of everyone on the planet.Secondly，we should develop good habits in our daily life.Paper cups are made from cutting forests.We should try not to use them because trees can absorb carbon dioxide and reduce greenhouse gases.Similarly，lights should be turned off when they are not used，which will greatly reduce electricity consumption.

In a word，small actions above can make a big difference.

“光阴似箭，日月如梭”，时间过得真快呀！不知不觉家乡发生了巨大的变化，不信你看！

记得几年前，我和爸爸妈妈回到故乡，那里故乡的路是泥路，沆沆洼洼，每到下雨的时候，路就变得脏兮兮的，到处是垃圾，路的两旁都没有垃圾桶。每当夜幕降临人们外出的时候，都会拿着手电筒，爷爷奶奶住的还是茅草屋呢，台风来临时，都会把爸爸奶奶的茅草屋刮倒。小河里的鱼都死了，水面还有许多垃圾袋，臭死人了，秋天到来时，人们拿着镰刀弯着腰在收割……

这次回家，过去的路变成了宽阔的水泥大路，路的两旁现在有了许多的垃圾筒，还有了路灯。爸爸奶奶们的房屋地变成了高楼大厦，小河鱼虾成群，鱼儿们又有了清澈的家园。人们都不用镰刀收割稻子了，用的是收割机，人们在空地上建了一个广场，每天吃完饭，一有空闲就会到那里唱歌、跳舞、下棋等等。

短短的几年里，家乡发生了如此惊人的变化，我更爱我的家乡了。

一转眼，十年过去了，我已经是一名大学生了，我乘着飞机来到了家乡--濮阳。啊!家乡的变化可真大。

走进濮阳，宛如走进了一座绿色的城堡。你看，宽阔平坦的公路两旁高楼林立、绿树成荫，绿化带内鲜花盛开，微风吹来，一阵阵花的清香在空气中弥漫开来，让人神清气爽。

咦，原来身着橘色衣服的清洁工不见了，换成了清一色的自动机器人，只要有垃圾、有污染，它们马上会自动启动智能按钮，立刻清扫垃圾，把被污染的空气转化为新鲜空气。

马路上飞驰的汽车，没有了噪音，没有了呛人的缕缕蓝烟，原来，现在人们开的都是太阳能汽车，既保护了环境又节能。

房子好特别，完全是一种新型的房子，它的外形很美，里面全是一种很轻的材料做成的，它很坚固绝不会倒，就算倒了也不会压死人，因为它很轻，所以再也不怕地震会给人们带来灾难。

十年后的家乡变化可真大，我爱我的家乡。

我相信，我的家乡将会变得更加繁荣、美丽!

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.

[关于环境污染的大学英语作文

地球是我们的妈妈，也是我们的家园，所以，我们要保护环境。让我们的家园变得更美好!

现在，有一些地方不保护环境，让环境受到了严重的破坏。例如：有些工厂排放油烟，让空气受到了污染;有些地方乱砍树木，让树木受到了伤害。

为什么现在的空气不清新甜润了?为什么人们生病的数量增多了?那都是因为空气呀!现在的空气不舒服了，让人们感到有许多尘土在空气里面。是啊!有许多灰尘和尘土都躲在空气里。树木也跟空气息息相关，树木能把脏空气换成清新的空气。电动车、摩托车等一些机动车也会污染空气的哦!有些工厂会污染空气，但是，你们可以买些空气净化系统，把空气变得清新一点。

我们喝的水和其他的水也收到了污染。我们要节约用水，节约的水对我们也有帮助。河水在我们的心中，可我们为什么不保护河水呢?我们应该保护河水，不让河水受到污染。

有一天，我回到了我的老家。没想到变化那么大。河水变得像泉水一样甜;天变的湛蓝湛蓝的;工厂真的用了空气净化系统;空气变的清新甜润。我就把这种方法教给了全国人民，最后，我们过上了美好的生活!

同学们，保护环境，人人有责，我们赶快加入吧!

几年后，我的家乡变化可大了，楼房耸立，空气清新、人人保护环境，美不胜收。

春天，一幢幢高楼大厦，被花草树木环绕着，道路两旁的花坛，好像为我家乡的织了个朴素的花环。每当夜幕降临，楼房大小不一，挨家挨户的看，都点着和谐灯，在自己的房子里，快快乐乐，过着幸福美满的生活。十分热闹。

夏天，天空碧蓝碧蓝的，一朵朵洁白的云朵，飘浮在天空中。忽然，夏婆婆变脸了，下起了倾盆大雨，哗啦啦，啊！好凉爽，雨停了，碧空如洗，不一会儿，出现了一道美似仙女的彩虹，美丽极了。

秋天，人们最喜欢的葡萄成熟了。一大串一大串的挂在绿叶底下，晶莹剔透。有的鲜艳似玛瑙，晶莹如珍珠。到这里游玩的人们不约而同地发出赞叹。摘下一大串葡萄来解渴，那酸甜可口的汁水映入你的心田。

冬天，下起了鹅毛大雪，像玉一样洁，像银子一样白，像云一样轻，像柳条一样柔，纷纷扬扬从彤云密布的天空中向下撒落，玉树琼枝。

几年来，我家乡的变化大吧！欢迎大家到我的家乡来游玩，人们会很热情的招待你的。

初来到家乡，一切都感到陌生，可我却感觉的它很美很美，让我流连忘返。

早晨，空气清新，迎面送来的凉风会使你神清气爽，“咕咕咕”听！大公鸡早早的鸣叫。“咯咯咯”听！母鸡又下蛋了。鸟儿也唱起了欢快的歌儿。太阳把温暖洒向大地，柳树吸取阳光变的充满活力。

中午，天气不像早晨那么凉爽，知了热得不停的叫：“知了，知了。”鸟儿也无精打采。乡下的孩子便跑到小溪边，洗一把脸，还打水仗呢！这给家乡增添了几分乐趣。

夕阳像个醉酒的汉子，红着脸向回家的方向走去，一眨眼的工夫，大地变的通红通红，大地像披上一层红红的轻纱，比七仙女织锦缎美丽。

晚饭后，劳动一天的农民们便各自寻找自己的快乐；爷爷奶奶拉上孙子孙女，他们依偎在爷爷奶奶的怀里，倾听那古老的传说。

深夜，虫不鸣了，人们进入了甜蜜的梦乡。小路上不时传来几声狗叫声

[描写家乡的环境作文400字

Many years ago, before I moved to the city, I lived in a small town. I was so close to the nature, I could see the mountain and the clear water. I remember the town became especially beautiful after the heavy rain, the air was so fresh and I felt a little cozy, it was like a gift from god in the hot summer. The mountain looked so clear over the heavy rain, it just washed by the rain. The things around me were so green. I love living in the town, I especially like the town when it was washed by the rain. At that moment, nature and me were united, we just like a group.

我们家乡的环境是怎样的？空气清新甜润，Pm2.5达到了优？还是空气依然不好呢？

我们假设空气非常不好吧：空气污染主要来源于汽车排放尾气过多，工厂第二次排放污染物……

工厂主要是排放污染过的脏水，从烟囱里冒出的黑烟，一些工人随意丢弃的一次性饭盒，一袋袋垃圾扔进清澈见底的小河小溪里

如果我们再继续这样接二连三的破坏环境的话，可能每次出去都要戴上口罩了。不然一出去，就连十分钟也呆不了了。

所以我倡议：多种绿色植物，少砍伐树木，多骑自行车，少开车。

让我们一起从现在开始，保护我们的生存环境吧！

Henan has a humid warm-temperate climate. Dry and windy in winter and spring, the province is hot and rainy in summer and bakes in strong sunlight during the autumn months. Rainfall averages about 600-1000 millimeters increasing from north to south, as does the annual temperature which increases from about 12.8C in the north to 15.5C in the south.

Henan province is considered the cradle of Chinese civilization due to its location on the Yellow River. This rich historic heritage has endowed Henan with numerous historic treasures, from primitive dwellings to earliest wheel thrown pottery. The remains of some of the earliest human settlements have been unearthed here, including the over 7000-year-old Peiligang Culture Site, the 6000-year-old Yangshao Culture Remains and the 5000-year-old Dahe Culture Remains. All these cultural remains have profound significance in the history of Chinese civilization.

Luoyang City has been the capital of nine dynasties since the time of the Eastern Zhou Dynasty (770BC-221BC). There are many historical sites to be viewed in Luoyang as well as the opportunity to purchase replicas of the famed Tang three-glaze horses. Luoyangs Longmen Grottoes, famous for its grand treasure trove of Chinese Buddhist statues, are located 12km (7 miles) south of Luoyang. First sculpted and chiseled around 493 AD when the capital of the Northern Wei Dynasty (386-534) was moved from Datong City to Luoyang, the grottoes of Luoyang house an awe-inspiring collection of sculpted Buddha and other religious subjects.

Kaifeng, one of the ancient capitals, also boasts the following buildings worthy of a visit: Iron Pagoda (Tie Ta) of the Northern Song Dynasty (960-1127), Dragon Pavilion (Long Ting) - site of imperial palace of the Song and Jin dynasties - and the 1400-year-old Xiangguo Temple which is one of the most famous Buddhist temples in China. Also on view in Kaifeng are ruins of the Shang Dynasty, an important part of human cultural and historic heritage. The Shang Dynasty Ruins, also known as the Yin Ruins, are famous because of the unique style of the large palace and its grand mausoleums, in which emperors of the Shang Dynasty are buried. The bronze vessels of the Shang Dynasty, which were both finely decorated and popularly used by the citizens of the Shang Dynasty, are well-known at home and abroad.

Depending on personal experience, personality type and emotional concern, we find that some people hold the idea of living in the country, while others prefer living in the city. In my opinion, I prefer the city life, though it has advantages and disadvantages.

First of all, city life is very colorful. City is the center of the surrounding area. So, it is also the most booming place having the best things. There are many great things and wonderful activities in the city, while there isn’t in the country. For example, there are KFC, wonderful shopping mall, delicious food from various places, dancing club, different kinds of activities and so on. We can also learn the culture from all the countries. Despite city life is so wonderful, it still has many disadvantages. Nowadays, with the improvement of people’s living standard, people have more cars and more people come to city, and then the city becomes more and more crowd. As a result, traffic jam emerges, which makes great inconvenience for people to go out. What’s worse, the air pollution becomes serious day by day, which is bad for people’s health.

To sum up, every coin has two sides. Living in the city also has good side and bad aspect. Whether like living in city or not depends on individual thinking. As myself, I like living in city though I know the disadvantage of living in city.

这个星期五，老师让我们写十年后家乡的环境，这个问题我想谁也想不出来，十年后应该是什么样子呢?

我想十年后的家乡环境应该是空气清新甜润，没有一点垃圾和一点臭味的一个地方。

我想以后科技更发达了。比如，房子就可以绿化环境了，每当环境不好的时候，房子就会伸出好多只机械臂，把周围种上高大又粗壮的树、绿油油的草、各种各样的花来绿化环境。

每到夏天，要是有垃圾和臭气的时候，就会有许许多多的和茶叶盒一样大的迷你运输车，把垃圾运走，送到工厂做成有用的东西。再由房子顶上的风扇把臭味吹走，让好的空气到这里来。

以后不用停车的仓库，还能把车停在自己的家里。每家都有两个塑料蛋，只要把这个蛋放到车的顶上，汽车就会自己到蛋里去，这样，汽车就不会停得杂乱无章了。这个蛋还能把车里没用的东西变成油，还能安在汽车的前边，汽车排出来的烟就能变成油用。

十年后的家乡的环境我也不知道是什么样子，可能车库在天上，机器打扫垃圾。只能等十年后看看了。

我的老家回江苏的，奶奶家旁边有一条小溪，那里有芦苇，有的时候，还会看到很多蜂鸟。就在我们今年回老家的时候，小溪的水，被污染了。

我看到芦苇都没有了，小溪的地下都是易拉罐、酒瓶、碎玻璃。我看到了，我很惊讶，我就问爸爸：“爸爸为什么会这样？”“因为有人乱扔垃圾，破坏了大自然啊。”爸爸说完，我就回房间了。

我上网查了很多的资料，我觉得有一些很有用，就让爸爸打印下来了。

这是我上网查阅的资料：

水的重要性：水是生命的源泉，是生命存在与经济发展的必要条件，同样是构成人体组织的重要部分。水在人体内的含量达70%，其余30%左右为固体营养物（蛋白质、碳水化合物、脂质、矿物质、维生素等）。人体60%的水在细胞内，40%在流体内（血、消化液、唾液、胆液、泪水、汗液、肠液、胃液）。

明代李时珍在本草纲目中著到：“药补不如食补，食补不如水补”，水不愧为百药之王。由有害化学物质造成水的使用价值降低或丧失，污染环境。污水中的酸、碱、氧化剂，以及铜、镉、汞、砷等化合物，苯、二氯乙烷、乙二醇等有机毒物，会毒死水生生物，影响饮用水源、风景区景观。污水中的有机物被微生物分解时消耗水中的氧，影响水生生物的生命，水中溶解氧耗尽后，有机物进行厌氧分解，产生硫化氢、硫醇等难闻气体，使水质进一步恶化。

看到这些，我们一定要好好的保护地球，这样，才不会给我们带来自然灾害。

一转眼，四年过去了，我的家乡变化可大了！瞧！家乡就像一个美丽的大森林街道上干干净净，没有任何灰尘，绿树成阴，鲜花盛开，我们生活在绿色的世界里。

看看这样的家乡再看看四年以前的家乡。四年前我的家乡树木很少，刮大风时，尘土飞扬五颜六色的塑料袋也随风飘舞。空气糟透了。

那时人们不爱护身边的环境。就说我们家吧！我家的门口有条河，河里养了许多金鱼。可人们总把水果皮、树枝，包装纸扔进水里。时间一长河水都变黑了，鱼儿都死了。这都是人们不爱护环境造成的。

你看，如今我们在这么美丽的环境生活，多么幸福啊！我们要把环境保护到底，让家乡永远这么美丽！
