It has been billed as a hi-tech bike-sharing boom that entrepreneurs hope will make them rich while simultaneously transforming Chinas traffic-clogged cities.

But, occasionally, dreams can turn sour.

In the southern Chinese city of Shenzhen, more than 500 bicycles for hire have been found dumped in huge piles on the streets, according to reports.

Pictures showed jumbled stacks of vehicles nearly three metres high, with handlebars, baskets and other parts scattered on the ground.

City streets around the country have seen an explosion of the colourful bikes that users can rent on demand with a smartphone app and then park wherever they choose.

The sharing economy is taking off in China, where ride-sharing and Airbnb are increasingly commonplace.

From Shanghai to Sichuan province, bike-sharing schemes are being rolled out in an effort to slash congestion and air pollution by putting a country once known as the "Kingdom of Bicycles" back on two wheels.

Companies such as Ofo and Mobike, with their rival fleets of bumblebee yellow and fluorescent orange bikes, have been locked in a cut-throat battle for customers.

But problems have arisen when clients have abandoned their cycles.

"Some people these days just have really bad character," a man named He, who lives near where the stacks appeared, told the Southern Metropolis Daily.

"When theyre done using (the bike) they just throw it away somewhere, because theyve already paid."

In the past few days he witnessed people demolishing the bikes before discarding them on the side of the road, he said.

Residents told the paper that bikes had been piling up over the past week, either parked haphazardly by careless users or stacked by local security guards trying to clear narrow residential alleys and footpaths.

Zhuang Chuangyu, a representative at Shenzhens municipal peoples congress, said the city needed to step up regulation of the bike-sharing industry in order to improve traffic conditions and safety standards, especially since schoolchildren often used the bikes.

In 1980, almost 63% of commuters cycled to work, the Beijing Morning Post reported in 2015, citing government data. But by 2000 that number had plummeted to 38% and today it stands at less than 12%.

Car use, meanwhile, has rocketed. In 2010 China overtook the US to become the worlds largest car market, with 13.5m vehicles sold in just 12 months.

The World Environment Day is on June 5th Every year. Since 1960s, the pollution on the earth have got more and more serious.

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.

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。

We live earth is deteriorating rapidly, did we have to pay attention to their own living environment cause harm to nature, you must not throw sundry, especially those serious pollution of garbage, waste batteries, for example, because the section waste batteries contain heavy metals, if flow to clean the water, it is very much pollution, then try to save trees made items such as paper, pencils, because waste these things is the destruction of the forest. Also try to use less disposable lunch box, chopsticks and plastic bags and other items, so as to avoid unnecessary waste and reduce waste.

There are some tips: walking to closing the master switch, in order to avoid electrical appliances overheating explosion, a waste of money and waste of electricity, save water, to shut the tap when brushing your teeth, wash dish water to rice, rice water to water the flowers, wash water can sweep the floor, so we can reduce some waste. 12 dont hunt wild animals, animal protection is absolutely cant kill, but dont kill the common animals such as frogs, because frogs eat 15000 bugs for us, and most are pests. Some people often dont think that is, the stubborn still, so we should try to eat less wild animals, lead to wild animals, the drop in sales no longer killing of wild animals.

Our forest is called oxygen plant, so to take good care of flowers and plants, not to destroy the city greening, and actively participate in. But also to cut down trees less, dont waste wood items, because waste these things is to destroy the forest, so be used sparingly, to protect the forests of less and less.

Use energy-saving lamps to replace the ordinary light bulb, although some expensive but can use less electricity. I appeal to you: in our daily actions to protect earths environment, let our children and grandchildren live in a beautiful environment!

我们生活的地球正在迅速恶化，我们不得不注意一下自己的生活环境有没有对大自然造成危害，大家必须必须别乱丢杂物，特别是那些污染严重的垃圾，比如废电池，因为一节废电池中所含的重金属，如果流到清洁的水中，它造成的污染是非常厉害的，其次要尽量节约纸张、铅笔等树木造的物品，因为浪费了这些东西就是毁灭森林。还要尽量少用一次性饭盒、筷子和塑料袋等物品，以免造成不必要的浪费和减少垃圾的产生。

还有一些小建议：走时要随手关总开关，以免电器过热爆炸，浪费钱又浪费电，要节约用水，刷牙时要关紧水龙头，洗菜水可以淘米，淘米水可以浇花，洗衣水可以拖地，如此就可以减少一些浪费了。不要随意捕杀野生动物，一二级保护动物是绝对不能杀的，但也别捕杀青蛙等常见动物，因为青蛙为我们吃掉1.5万的虫子，而且大部分是害虫。有些人经常不以为是，依旧我行我素，所以我们要尽量少吃野生动物，导致他们野生动物销售额下降，不再捕杀野生动物。

我们的森林被称之是氧气加工厂，所以要爱护花草植物，不要破坏城市绿化，还要积极参与。而且还要少砍伐树木，别浪费木质的物品，因为浪费了这些东西就等于毁灭了森林，所以要少用，来保护越来越少的森林。

用节能灯炮来代替普通灯泡，虽然有些贵但是可以相对的少用一些电的。我呼吁大家：用我们的日常行动来保护地球的环境，让我们的子子孙孙生活在一个美好的环境中!

Although the world develops much faster and better，the resources on the earth get fewer and fewer.In order to protect them，something must be done。

Save water. Water is the source of life. No water，no life. So its very important for us to do so.Not only should we protect drinking water and stop polluting it，but also make full use of it。

Save electricity. It is crucial. We cant imagine what the life will be like without it.Everyone should do his best to save electricity. Dont forget to turn off lights or other electric machines when we finish working。

Save forests. They are useful .Please stop cutting them down and use recycled paper instead. Make our world a green one to live in。

Recycle useful rubbish. Plenty of rubbish can be recycled like cans，paper，bottles，and so on。

We can save resources in this way. I believe we can make the world a better place to live in。

尽管世界发展更快、更好,地球上的资源得到越来越少。为了保护他们,必须得做点什么。

要节约用水,水是生命之源。没有水,就没有生命。所以这对我们来说是非常重要的。我们不仅应该保护饮用水和停止污染,但也充分利用它。

节约用电。它是至关重要的。我们无法想象没有它的生活将是什么样子。每个人都应该尽力节约用电。别忘了关掉灯或其他电动机器当我们完成工作。

拯救森林。他们是有用的。请停止切割下来,转而使用再生纸。让我们的世界一个住在绿色。

回收有用的垃圾。大量的垃圾可以回收罐、纸、瓶子、等等。

以这种方式我们可以节省资源。我相信我们可以让世界变得更美好。

Almost every country in the world faced the population problem.China has the largest population, so the one-child policy was necessay. In America, there were 2 billion people 20 years ago, now there were 3 billion. Some day they will have the same amount people as we had in china, will they apply our population control policyAnyway we could be sure they will not critize our population policy at that time.

Everyone should protect the environment, this is the law of nature, if not protect the environment, the world will be contaminated.

To protect the environment from every bit of small start, and I have not done well. Have a New Year, we went to shun feng mountain park, riding a bicycle, we were hungry, we bought a small bag of snacks to eat, while I, eat snacks, I happy too much because it is over, so casually took me to once eat 7 packet snacks packaging thrown on the ground, and then I went in a convenience store in watching TV, while todays TV is very good-looking, half an hour later, I put the mother with all I said before, all my thoughts are indulged in the drama. After 30 minutes, I didnt think of it, but, at that time, his mother angry of say: "you this smelly wenches, didnt I tell you before to protect the environment, you forget?" I said: "Im not forget, I just from watching TV." Mother said: "some important watching TV, or picking up litter some important?" I said: "rubbish." Mother said: "you hurry up to pick up."

And then, I picked up a small pile of junk, throw in the trash, I apologized to his mother not only, I also to shun feng mountain park, sweep the floor every aunt to recognize the fault. Because, if everyone throw a piece of garbage on the ground, and then will add burden to clean the aunt. If you see a piece of garbage on the ground, then you are curved waist, and activities, do a man to protect the environment, is to clean the aunt to reduce burden...

, although it has been over the past year, I learned about it, if the world all throw a piece of garbage on the ground, the whole earth will become a waste, so each of us should protect the environment, protect the earth, the world will be more beautiful!

人人都要保护环境，这是大自然的规律，如果不保护环境，世界就会被污染。

保护环境是从一点一滴的小事做起，而我却没有做好。有一次过新年，我们去顺峰山公园游玩，骑完自行车，我们个个都饿了，我们买了一小包零食来吃，而我，吃完零食，我因为高兴过头了，所以随手就把我吃过的7包零食的包装扔在地上，然后我进去便利店里面看电视，尽管今天的电视剧很好看，过了半个小时，我把以前妈妈跟我说的话忘得一干二净，我所有的心思都沉迷在这个电视剧里面。在过了三十分钟，我才想起来，可是，这时候，妈妈生气的走过来说：“你这个臭丫头，难道我以前跟你说的要保护环境，你都忘了吗?”我说：“我不是忘了，我只是顾着看电视。”妈妈说：“看电视重要一些，还是捡垃圾重要一些?”我说：“捡垃圾。”妈妈说：“那你快点捡呀。”

然后，我捡起一小堆垃圾，扔进垃圾桶，我不但向妈妈认错了，我也向顺峰山公园的每一个扫地阿姨认了错。因为，如果每个人都扔一块垃圾在地面，那么就会给清洁阿姨增加负担。如果你看见一块垃圾在地面，那你就弯弯腰，动动手，做一个保护环境的人，那么就会给清洁阿姨减少负担……

虽然这件事已经过去一年了，但是，这件事让我学会了，如果世界上都扔一块垃圾在地面，那么整个地球就会变成一片废区，所以我们每个人都要保护环境，保护地球，世界才会更美好!

Environmental problems are becoming more and more serious all over the world. With the development of industry and agriculture, cars make great noises and give off poisonous gas. Trees on the hills have been cut down,and waste water is being poured continuously into rivers.

Furthermore,wherever we go today, we can find rubbish carelessly disposed. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to mans existence.

We must face the situation that exists and take actions to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the pub!ic must receive the education about the hazard of pollution and so on. We hope that all these measures will be effective and bring back a healthful environment.

全世界的环境问题在变得越来越严重。随着工农业的发展，汽车制造噪音、排放毒气，山上的树木被砍伐，污水不断被排入河里。另外，无论我们走到哪里，到处可见随意丢弃的垃圾。整个地球生态平衡正在改变，环境的巨大破坏已带来负面影响，甚至对人类生存带来巨大威胁。

我们必须面对现实，采取行动解决环境问题。例如必须通过新的法律严格控制工业污染问题，大众必须接受污染危害的教育等。我们希望这些措施的有效实施能带给我们一个健康的环境。

Environmental problems are as big as not for individual country or individual people to address。 In other word， we have reached the stage that environmental problems be solved for international view。 To what extent do you agree or disagree?

In recent years， many nations have bee more aware of the environmental issues each nation faces， such as air and water pollution。 The question is， are the environmental issues a national problem or an international problem? It is my belief that the environmental issues have grown to the point of being an international problem needing international cooperation to resolve。

Because of the differences in environmental policies， resources and technology， international cooperation could provide quicker results and have a greater impact on bringing resolution to environmental problems for nations of differing environmental policies and of lesser resources and technology。 By pooling international resources and technology to address the environmental problems， the disadvantaged nations are provided the assistance needed。 Otherwise their environmental conditions deteriorate ultimately affecting the resources and environment of the world as a whole。

One of the difficulities to an international resolution to environmental issues is the difference in individual nations view and policies toward environmental protection。 In order for international cooperation to occur and succeed， the nations of the world must submit themselved to international standards and supervision by an international mission elected by the participating nations of the world。 All members must agree to abide by the standards established。

The environmental issues facing each country are not unrelated to the well being of the rest of the world。 The impact is long term and international in scope。 Without international cooperation and agreement to address such environmental issues as glacial melting at the South Pole， depletion of the ozone layer， water pollution， air polution， etc。， the environmental conditions of the world will deteriorate to the detriment of every nation， not just those that ignore or lack the resources and technology to resolve their individual environmental problems。

As part of the same planet， it is the responsibility of each individual and nation to protect the global environment。 Only international cooperation will provide the timely solutions and the effectiveness needed to stop the deteriorating global environment。

Nowadays,the problem of piracy has become more and more serious. Books,tapes,VCDs and others high-tech products have been pirated. For instance,when a new product comes onto market,most probably,its pirated counterpart will soon put on its appearance in the market,too. Piracy has caused a great loss to legitimate producers,inventors and writers in many ways. To start with,the pirated products often cost much less than the genuine ones so that they enjoy a better trading position in spite of their relatively poor quality. The genuine products,on the contrary,sell poorly. Whats worse,pirated books sometimes do great harm to the authorsreputation due to some misprints. In the long run,pirated products may have a negative impact on customers. Those legitimate producerscreativity and enthusiasm may be deeply hurt by the fact that some customers are more interested in the pirated products for the sake of small gains. In my opinion,its high time that everyone started the battle against piracy.First,customers should develop their consciousness to resist the pirated products.

Only in this way can we wipe the pirated products out of our life.

如今，盗版问题变得越来越严重。书籍，磁带，光盘和其他高科技产品已盗版。例如，当一个新产品出现在市场上，最有可能的是，它的盗版产品很快就会出现在市场上。盗版行为在许多方面给合法的生产者、发明家和作家造成了巨大的损失。首先，盗版产品通常要比那些正版的要低得多，以至于他们在质量相对较低的情况下享有较好的交易地位。相反，真正的产品卖不好。更糟糕的是，盗版书有时危害巨大，由于一些作者错误的观点。从长远来看，盗版产品可能会对客户产生负面影响。那些合法的生产者的热情，也许是因为有些客户是在盗版产品为了少的收益更感兴趣，深深的伤害了。在我看来，每个人都开始了打击盗版的斗争，第一，客户应该发展他们的意识，抵制盗版产品。其次，政府应采取有效措施，结束盗版。最后，法律必须严格执行，完全禁止盗版。只有这样，我们才能把盗版产品从我们的生活中抹去。

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.

On Water Shortage

No one can have failed to notice the fact that water shortage is a grave problem with which the whole world is confronted. Actually, it has become so widespread that it has severely affected peoples daily life and hindered the development of the global economy.

A number of factors could account for the problem, but the following might be the critical ones. First, with the development of agriculture and industry, an increasing amount of water is needed. Secondly, the ever-increasing population is another leading cause of water shortage. Besides, the global tendency of warming up also contributes to the problem. Whats worse, pollution and waste of fresh water aggravate the situation.In view of the seriousness of the problem, effective measures must be taken before things get worse. First, it is essential that laws and regulations be worked out and enforced to protect water resources. Secondly, people should enhance their awareness of saving water. With these measures taken, it is reasonable

for us to expect a brighter future.

邢台市市长：

您好！

我是英华小学六（7）班的一名少先队员。我发现近期的雾霾现象十分大。

我们早晨起床下楼去操场跑操的时候，我就看见到处都是雾蒙蒙的，到处都被雾霾笼罩着。我们只能看见眼前几米的距离，再往前就只能看见白雾了。这就和傍晚差不多。

这可怎么跑步啊！万一跑道前面有个障碍，小排头说不定没看见就摔倒了。体委看到这样的场景，就只好带我们回教室了。

就这样过了五六天，雾霾这才减少了一些，我们才准备上操。给我们喊口号的体育老师对我们说：最近的雾霾现象很大，我们就不要跑步了。

我在电脑上查了资料，才明白原来雾霾是因为：1、一些工厂排放出来的黑烟2、空调、电脑等排放出来的二氧化碳3、到处都没有什么树木，吸收的二氧化碳自然也就少了

而这样会导致感冒、过敏等疾病在雾霾天更易发作或加重；雾霾中的一些病原体会导致头痛，甚至诱发高血压、脑溢血等疾病；雾霾天气还可导致近地层紫外线的减弱，使空气中的传染性病菌的活性增强，传染病增多。

我们生活在这样的环境下，没有感觉到十分可怕吗？所以，为了我们能生活在一个优美的环境下，为了不再让我们的城市因环境而出名，我们一定要保护环境。我建议我们应该这样做：

1、 尽量多植树，不要浪费纸张。

2、 出门时尽量乘坐公交车，不要开私家车。

3、 每天最多打开电脑一两个小时，不要开太长时间。

4、 在夏天，开空调时如果没有那么热，调温度时可以调高几度，尽量不要开太长时间。

5、 如果家里是开场子的，排放出来的黑烟，一定要经过处理，不要直接排放在空中。

我的学校坐落在金水河旁，金水河两旁大树成荫，小草茂盛，还有很多不知名的小花。河水缓缓流过，看起来不怎么清澈，可能是这几年受到了污染。我家就租住在金水河和学校的旁边，每天早晨都有许多来来往住的小学生，尽管人很多，却从没有发生过，你拥我挤的情况，并且她们都穿戴整齐，也都穿着学校发的校服。学校后面有一个“小花园”，操场上也有棵棵挺拔的樟树，它就像士兵一样，日日夜夜守卫着校园。学校多美呀，可曾经它却被我“伤害”过一次。

今天天空阴沉沉的，似乎天空要哭泣一般，花草低下了头，连那些“士兵们”都垂着头，而今天是我值日，我更加是打不起精神了。不一会儿，簸箕里装满了垃圾，在学校的垃圾箱上清清楚楚写着：“请讲卫生，垃圾入箱。”这行字白底红字，特别醒目。我双手端着满满一簸箕垃圾，不知是簸箕太重还是懒得靠近，就存离垃圾箱还差两步远时，我就冲着箱口，用力把簸箕一倒，“叭——”地一声，簸箕里的垃圾一小部分被垃圾箱“吞”进了“肚子”里，而另一大半撒落在了箱外。就当我自以为没什么，要转身往回走时，背后突然走来了我的语文老师，我立马向老师问好，语文老师往垃圾箱那一看，神情突然变得严肃起来，语重心长地对我说：“谢恩婉你忘记了要保卫环境了吗？金水河之所以被污染，就是有太多人将垃圾排放进了金水河。你这样乱丢垃圾不但会污染环境，而且还会影响我们学校的形象。你想想如果人人都像你一样乱丢垃圾，那么每次下大雨，污水就会被冲到金水河里，我们所喝的井水、自然水，都是金水河里的水，并且根本没有过滤过，如果‘垃圾’再进入人体，那结果会不堪设想啊！”老师说完后轻轻地拍了拍我的肩。我顿时感到心酸，我从没有考虑过我这样做的后果，甚至还自以为然地认为这样做根本不会有事。羞愧使我红了脸，于是我马上跑回教室拿来扫把和垃圾夹，把我扔在垃圾箱外的垃圾用扫把打成一堆，然后再用垃圾夹小心翼翼地夹入垃圾箱里。我不经意间，看到操场的樟树下面，有些树叶树枝和一些小朋友乱丢的纸屑，我马上跑过去，用垃圾夹把树叶树枝和纸屑全部夹到垃圾箱。来回走了好几次，额头上都冒出了汗珠，老师看着我露出了满意的笑容。

第二天，我刚刚上完第一节课，校长走进了我们班教室，当众表扬了我，说我是一个保卫环境的小卫士。在一阵阵热烈的掌声中，我越来越高兴，没想到一个小小的举动，有那么大的回报！

是我的语文老师让我渐渐地懂得保护环境的重要性，保护环境不单单是喊口号，而是要用实际行去表现它！让我们行动起来，保护环境，人人有责；从我做起，从现在做起！让我们的学校变得更加干净整洁！

我们美丽和谐的校园已有了70多年的建校历史了，在这70多年中，学校发生了许多的变化，想知道近几年来的变化吗？那就跟我来吧！

在学校的大门前，就有一处变化：学校大门的两根柱子上贴了两块用木头刻出来的对联；走进学校，你会发现学校里面种着许多花草树木，柳树特别的多，，微风一吹，她就开始摇晃自己长长的，柔软的小辫子，一到秋天，，每棵树上的叶子就飘落下来，远远望去，就像一只只美丽的蝴蝶在翩翩起舞，等到每棵树上的叶子都快要掉完时，光着脚，在已经发黄的，像蝴蝶一样的树叶上散步，就会觉得像是踩在云朵上一般，感觉特别舒服。再转向左边，可以看见学校五年前修建的新阶梯教室，有一扇漂亮的玻璃门，走进里面，你的第一感觉肯定是大，白，亮，前面是学生的座位，后面是听课老师的位置。新阶梯教室的上面是学校去年修建的微机室，它的美，可以让我们用豪华来形容它，里面有美丽的窗帘，透明的玻璃桌以及液晶电脑，还有老师用的电脑，讲桌和两块电子白板……再往前走，就可以看见一个宽阔，平坦的操场和三栋高大的教学楼，我们的教学楼有三层，最上面的一层是我们的六年级的教学楼每个教室都有一台电脑和一张张整齐的桌椅，它们是我们忠实的伙伴，陪我们一起读书，写字，上课……学校的操场就是我们的乐园，里面有一个篮球场，兵乓球桌和一根树立在旁边的旗杆，操场外面还围着一个长400多米的跑道，这个跑道也是几年前才修建的，去年又给它刷上了红漆……

我希望我们的校园能越变越美，我祝她永远年轻！
