View of two children

now, our country the number of straight line rise, because the two population increasing, a series of problem, here, Ill give you something about with that!

The current family planning policy is unfair, urban residents having only one child, rural residents the first child is female of, can have two children. To have two children, however, leads to the housing problem, population increase, also takes more house, now scientists show that Chinas housing life for 30 years, while western countries housing service life is 2 times of our country, therefore, our countrys house of fast, down too fast, the house is always not enough, so a few people who are facing problems dont have a house to live.

Today, our countrys arable land has also been a lot of problems, such as: 1, due to the large area reclamation woodland lawn, cultivated land is widening. 2, due to the large-scale afforestation, reduce cultivated land quickly. 3, due to water loss and soil erosion, land desertification, human development blindly, arable land decrease quickly. 4, due to the impact of foreign agricultural products, a large number of cultivated land desolate. Because of population increase, to a large number of land reclamation, to a large number of occupation of land, only in this way can we have a new technology, will have a house to live in. So, our countrys land area is greatly reduced. But, our country a lot of land is occupied, can continuously reduce the cultivated land area, arable land decrease, many kinds of food less, even some people starve to death. Two population increase, the employment problem also more and more competition, such as: 1, the our country population base is big, need more employment, employment peak last a long time. 2, needs to improve employment mechanism, talent market, labor market development has yet to be perfected, labor elements configuration has not yet reached full optimization. 3, employment concept updating, lack of initiative entrepreneurial enthusiasm, "such as" "by" the ideas of the "to" still exist, not from their own and realistic environment, employment expectations are too high. So, young people in employment in our country may not work, cant bring home the bacon. In order to themselves and others in the future, please have fewer, eugenics. Boy or girl, is the backbone of the motherland in the future.

对二胎的看法

现在，我国的人数直线上升，因为生二胎人口增多，造成的一系列问题，下面，我给大家加讲一讲吧!

现行的计生政策不公平，城市居民只能生一胎，农村居民第一孩字是女的，能生二胎。可是，生二胎会导致住房问题，人口增多，需要的房子也多，如今科学家证明我国的住房寿命达30年，而西方国家的住房寿命是我国的2倍以上，所以，我国的房子修的快，拆的也快，房子始终不够，因此少数人正面临没有房子住的问题。

如今，我国的耕地也受到了很大的问题，如：1、由于大面积垦林地草地，耕地不断扩大。2、由于大规模造林，使耕地迅速减少。3、由于水土流失，土地沙漠化，人类盲目开发，耕地面积迅速减少。4、由于外国农产品冲击，大批耕地荒芜。就是因为人口增多，才大量的开垦，才大量占用土地，就只这样我们才能有新科技，才会有房子住。所以，我国的耕地面积大大减少。可是，我国大量的土地都被占用，耕地面积就只能不断的减少，耕地减少，种的菜就少了许多，甚至有些人被饿死。生二胎人口增多，就业问题竞争的人也越来越多，如：1、我国人口基数大，需要就业人员多，就业高峰持续时间长。2、就业机制有待完善，人才市场、劳动力市场发育还有待完善，劳动力要素的配置还未达到完全优化。3、就业观念有待更新，缺乏主动择业创业的积极性，“等”“靠”“要”的思想仍然存在，不从自身和现实环境出发，就业期望值过高。所以，我国年青人在就业方面有可能没有工作，就不可以养家糊口。为了自己和他人的未来，请少生、优生。生男生女都一样，都是祖国未来的栋梁。

What are the purposes of places such as museums and how should they be funded?

Nowhere in the world has the issue of museums progress been so much debated as in our society. Nowadays, more and more museums have to face the serious economic problem. Therefore, many people doubt museums existent signification. In this essay we will discuss the existent signification of museum and the solutions, such as buying by government and supporting by society

Firstly, museum is considered the historical symbol that it exhibits traditional culture of a nation. Nations of difference have different culture and history. The museum is the best way to let the younger generation savvy their ancestors history and let visitors and foreigners know varied culture and tradition.

Secondly, museum could save plenty of cultural relics that they are not destroyed and lost. The equipments of museum could perfectly save all kinds of displays.

As a result of the future of museum, the outlook is somewhat grim. People already realize this problem exists and are trying to solve it.

For one solution, the government ought to buy all museums. If museum belong to government, it will means main economic problem of museum is solved.

The second solution is that society ought to donate lots of money to maintain development of museum. The museum protects our history and culture, so we have obligation to support progress of museum.

The important thing is to protect current museums before its too late. Otherwise we will lose them.

博物馆的发展问题诸如博物馆和怎样资助他们的目的是什么？在世界上没有一个地方博物馆的进步问题如此多的辩论在我们的社会。如今，越来越多的博物馆不得不面对严重的经济问题。因此，许多人怀疑博物馆的存在意义。在这篇文章中我们将讨论博物馆与解的存在意义，如购买政府和社会的支持首先，博物馆被认为是具有民族传统文化符号的历史。国家有不同的文化和历史的差异。博物馆是最好的方式，让年轻一代精明的祖先的历史，让游客和外国人了解不同的文化和传统。其次，博物馆可以保存文物丰富，他们不被破坏和丢失。博物馆的设备能够很好地保存各种显示器。由于博物馆的未来，前景是有点残酷。人们已经意识到这个问题的存在，并试图解决它。作为一个解决方案，政府应该购买所有的博物馆。如果博物馆属于政府，这将意味着博物馆的主要经济问题。其次，社会应该捐了一大笔钱来维持博物馆的发展。博物馆保护我们的历史和文化，所以我们要支持进步博物馆的义务。重要的是要在为时已晚之前保护现有的博物馆。否则，我们将失去他们。

Protecting the Environment

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?

准备出门散步，却发现窗外风沙肆虐，黄沙漫天，我不由得抱怨：都怪那些伐木工，砍掉了树木，才带来了沙尘暴，带走了蓝天。

去大城市游览，却发现天色昏暗，雾霾遍天，我忍不住发牢骚：都怪那些化工厂，排放了废气，才使空气被污染。

去逛街，却发现街上垃圾遍地，污水直流，我开始责怪：都怪那些没素质的人，乱扔垃圾，乱泼脏水，才使街道变得肮脏。

环境的破坏，让我在心中一遍又一遍地埋怨破坏者：是他们！是他们破坏了环境！是他们让天空不再湛蓝，是他们让河水不再清澈，是他们让绿色一点一点消失！

我理所当然地浪费了一张又一张纸，理所当然地为求方便而坐了一次又一次汽车，理所当然地将垃圾一次又一次扔在地上。

因为，我觉得环境污染与我无关。

然而，报纸上一篇有关环境污染的统计，彻底否决了我的想法，我才发现，我错得很离谱。

我的书本堆满书桌，只用过一次的白纸塞满纸篓，我从没想过，它们其实就是被砍伐的某棵树的一部分。

本来可以骑车的我坐在小汽车上，汽车车尾排出白烟，我从没想过，排放出的有害气体，其实就会成为污染蓝天的一部分。

吃完烧烤，随手把竹签扔在地上，我从没想过，看起来细细的竹签，竟然也会成为污染环境的垃圾。

我总是认为环境污染是那些大工厂之类的巨大工程造成的，却从未想过，自己平时的行为，也是对环境的一种破坏，虽然是一些微小的行为，但是，一次又一次的破坏、一个人又一个人的破坏累计起来，就是对环境的一个巨大创伤。

环境的污染竟与我相关，这出乎我的意料，却又在情理之中。积少成多，聚沙成塔。一个人的力量很小，但是许多人的力量加起来，就是一股很大的力量，我想，保护环境也是如此，环境污染与我们息息相关，所以，我要做的，不应该是一味的埋怨，而是，从自身做起，爱惜环境。

因为，环境污染竟与我有关。

Green benefits more, it is much, this is the layman, but it how? What good?

On the earth, whether people or animals, no matter how much you if you want to survive, you must absorb a large number of oxygen, emit large amounts of carbon dioxide at the same time. But the earth is originally stored oxygen is limited, and there are not many, so oxygen should run out in N years ago, oxygen and from where to now? That is about to rely on the green plants.

Green plants can be in the sun for photosynthesis, absorb carbon dioxide to produce oxygen. Research shows that: each plants grow a ton, can produce five tons of oxygen. Absorb one ton of carbon dioxide per hectare of forest land every day, 0.735 tons of oxygen; Grass absorbs 0.9 tonnes of carbon dioxide per day per hectare, produce 0.6 tons of oxygen. So do not have oxygen on earth, as long as there is green in the city can also have the fresh air.

绿化好处多，实在是多，这是妇孺皆知的事情，可它究竟多在哪呢?又有什么好处呢?

在地球上，无论人或动物，无论你多厉害你要想生存下去就必须吸收大量的氧气，同时放出大量的二氧化碳。可地球是原本储存的氧气是有限的，而且并不多，这样氧气早该在N年前就用光了，现在的氧气又从哪里来呢?那就要靠绿色植物了。

绿色植物可以在阳光下进行光合作用，吸收二氧化碳，产生氧气。研究表明：植物每生长一吨，可产生五吨氧。每公顷林地每天的吸收一吨二氧化碳，产生0.735吨氧气;每公顷草地每天可吸收0.9吨二氧化碳，产生0.6吨氧气。这样一来地球上不就有氧气了，城市中只要有绿化带也可以有清新的空气了。

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.

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.

Eye can go to see the water there is green grass by the a bunch of with water. Yi? Why is there little orange in the water? Turned out to be a goldfish hidden in the grass to rest!

我努力嗅着四周弥漫着的绿色的泥土芳香，真没想到在城市的喧嚣与浮躁下竟有这么一处路边公园。周围都是绿的在公园正中有一个大水塘，水塘里的水碧绿的，清澈见底，使人总怀疑水底藏着翡翠，不然叫它哪儿去吸收那么多纯净的碧绿?一眼望下去能看到水中一簇随着水波飘荡着的绿色水草。咦?在水草中怎么会有点点橘红?原来是金鱼藏在水草中休息呢!瞧，那边还有几只在自由嬉戏，有的还正吃着水上飘浮着的点点浮萍。水塘面上绽放着几朵红色的荷花，在硕大的荷花的衬托下，它们显得更加妩媚，荷花娇嫩的花瓣上还留着透明的水珠，我的心为之一颤，深深地被这生命的娇艳陶醉了。

水塘周围都是绿草和绿树，有柳树，桦树，榕树，松树等，还有很多不知名的树。它们的枝干，叶子纵横交错，形成了一个绿色的凉棚，阳光透过绿叶照到草地上都变成了绿色。枝叶中跳跃着，闪烁着迷离的光点，像一个个绿色的小精灵。一天的劳累之后，人们在“凉棚”下的石椅上休息，该是多么的惬意啊。

走过石桥，来到了水塘旁边的草地上，草翠绿翠绿的像一块绿色的绒毯，草丛中点缀着朵朵野花。这是小朋友们的天堂。他们可以在这里荡秋千，滑滑梯。野花丛中有一朵粉色的花兀自静静地开放着，它那随着清风微微摇的婀娜的身影，透出了生命的活力与柔美。一个穿着一袭绿色连衣裙的小女孩跑了过来，小手正伸向那朵可爱的花儿，或许听到旁边稍大姑娘的“别摘”的阻止声，或许她头上的蝴蝶结与那花儿一样的柔美，或许，小女孩缩回了手，笑呵呵地蹦跑到玩伴中间，那绿裙一颤一颤地融在了翠绿的草丛中，一串串银铃般的笑声荡漾在充溢草香花香的空气里，在这绿和花的世界里，在小朋友们的笑声和丛林中的鸟啼声交织的乐曲里，在我的身心得到了极大的放松，课业负担的烦躁似乎都消失在这绿色的世界里。

啊，绿色多好，如果世界永远都像这样绿，那该有多好呀!朋友们，让我们好好地爱护环境，永远生活在绿色世界之中。

The proposal is from Wang Yuqing, a deputy director of the Committee of Population, Resources and Environment.

He is being quoted as saying he favors a gradual opening of a two-child per family policy, and says he believes the current limitations will be lifted by the end of the five-year plan in 2015.

The current family planning policy was initiated in 1979 to control Chinas rapidly growing population.

But some negative side effects have emerged, including a rapidly aging population.

Peng Xizhe is the Director of the Institute of Population Research at Fudan University.

"The one-child policy has fulfilled the goal initially set. Negative effects will pile up if it continues."

The President of Renmin University, Ji Baocheng, claims the labor force population between the ages of 28 and 40 will be halved in 10 years.

As an example, in Shanghai, which has the highest urban population in China, the number of Shanghai natives -- as in those with a Hukou -- has actually been dropping for the last 17 years in a row, even though the citys population has been increasing.

A possible reason for Shanghai parents not choosing to have a second child could be the rising cost of everyday expenses, particularly the cost of education.

"I dont think Ill have a second child if the limit is removed. Im simply a wage-earner, and I find it difficult enough to raise one child, so I wont consider the second."

But at the same time, there are still people who think it would be nice to have two children.

"I will think about it. A lot of parents now are the only child in families, to have two kids means they can look after each other in the future, and of course, therell be financial burden."

One-Child Policy has been relaxed in certain ways over the years.

In cities such as Shanghai and Beijing, if a couple is both the product of the one-child policy, theyre allowed to have two kids.

Certian ethnic minority groups have been exempt from the rules entirely.

And families in rural areas whose first child is a girl are also allowed to have a second child without punishment.

It remains unclear as to how the proposed two-child policy will work, though its being suggested that several big cities will be selected to try it before its brought in around the country.

For CRI, Im Wang Jing.

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 our natural resources and recycle our products.

We are sure that we can have a better and cleaner place in the future.

In general, there are two way of traveling, private cars and public transportation.

Chinese people should regard public transportation as their first traveling opinion.

First, there are so many people living in this countries that make it so crowded.

If each chinese people own a car, there will be far more traffic jams and accidents, which increase you impatience.

Moreover, there will be far more pollution resulted from cars. Once a car started, it release huge amount of dirty gas and heat, which lead to great pollution and result in green house effect.

st On January 2016, our country started to carry out two-child policy. It is good

and right for the development of our country now, because our country need more young workers. Many parents also want to have one more child. Althouth they may have some difficulties in affording another child’s life, education and so on, they will have another child to be with them. As for me, the only child in my family, I want to have a sister or a brother. Not only can we share happiness, but also we can help each other in our daily life.

2016年1月,我国开始实施的二胎政策。它是好的

现在对我们国家的发展,因为我们的国家需要更多的年轻工人。许多家长也想要一个孩子。虽然他们可能有困难提供另一个孩子的生活,教育等等,他们会有另一个孩子。至于我,我家里唯一的孩子,我想有一个姐姐或者哥哥。不仅我们能分享快乐,而且在我们的日常生活中我们可以互相帮助。

针对此次北京、天津、河北省中南部和中东部将再次出现的空气重污染过程，为加强区域空气重污染联合应对，降低污染程度，保障公众身体健康，京津冀及周边地区大气污染防治协作小组办公室已于12月4日印发《关于共同应对区域空气重污染的通知》，要求京津冀三地环保厅局加强空气重污染预警会商，密切跟踪空气质量变化趋势，及时启动应急预案，严格落实应急措施。

北青报记者昨天了解到，目前除北京已于12月5日下午提前发布空气重污染橙色预警外，天津以及河北省石家庄、邢台、廊坊、保定、衡水、邯郸、辛集(省直管市)、定州(省直管市)等9个城市已启动相应的空气重污染预警。

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。

The earth on which we live is to suffer from serious air pollution. The exhaust gas from the factory, the burning of waste, car exhaust and other pollution in the atmosphere are the source of trouble. The time of the invasion of the respiratory tract and lung, the incidence of respiratory rate increased year by year.

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。

When the air is polluted slightly, inhaled air can be part of the dust removal by nasal cavity in the nose, the nasal mucus in the bronchial mucus and the dust adhesion. Tracheal and bronchial cilia in tens of millions of their root, about 12 times per second to swing, like a "cleaner" from the bottom up sweep mucus in the respiratory tract, and throat, cough up through in vitro.

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。

When the air is seriously polluted, the purification effect of respiratory tract will be reduced, and even lost completely. In this case, respiratory tract and lung is vulnerable to the invasion of bacteria and diseases.

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。

Due to various reasons, the air pollution is getting worse. If you can not solve the problem of air pollution, I am afraid it one day, humans can only live with a mask.

how to solve the energy shortage（如何解决能源短缺问题）

energy shortage is a very serious problem in the world. many people worry that energy resources on the earth will be exhausted if we use them in an unchecked way. this, most people agree, will cause serious problems and even crisis and jeopardize the survival of mankind .

on the one hand, most people agree that the problem can be solved in one way or another. one is to conserve and save our energy. energy refers not only to coal, oil, or natural gases but also to goods, land and water, etc. most countries have realized the wastefulness in their using of energy. they are trying to conserve energy. for example, some countries have a daylight saving system to use less electricity for lighting. some cities have enforced water savers at public such as restrooms and bars. some have enforced serious penalties on overuse of electricity, water, and farming land. by these means, people hope the drain on energy resources could be slowed down.

however, conservation alone cannot solve the problem. another way, perhaps the best i think,, is to develop new energy resources. obviously, no matter how hard we try to save energy resources and how abundant they are, we will use them up sooner or later. i think there are many energy resources that we can develop and utilize. we don’t have to depend only on the current conventional energy resources. there are many other energy resources that we can develop such as nuclear power, waterpower and solar power. these resources, if developed, can completely replace the conventional energy and thus solve the problem of energy shortage.

Today， pollution has become a serious problem to us. It means that the air， seas， rivers and land are polluted by waste or poisonous things. It does harm not only to human beings but also to animals (It does harm to animals， as well as human beings.)。

We cannot have fresh air because many factories have the poisonous smoke sent into the air. Beautiful parks are made dirty by plastic tins and bags. Fish die from the polluted water. It is said that strange diseases have appeared in some places because of pollution.

I hope scientists can find ways to solve the serious problem. We are looking forward to seeing the clear sky， clean rivers and beautiful parks again.

近几年来，我们可以明显的感觉到我们身边的环境污染愈显明显，环境安全问题已十分严重。因为我国以往的政策方针是重经济发展，轻环境保护，所以造成环境污染、生态破坏十分严重，主要表现为以下几个方面：

在大气安全方面，20世纪中叶以来，工业和交通运输迅速发展，造成了大气污染的日益加重。大气污染既危害人体健康，又影响动植物的生长，破坏建筑材料，严重时会改变地球的气候。据调查显示，我国每年因大气污染造成的经济损失高达1000多亿元。

In the water security,waterpollution in Chinais very serious,widespread around thedrinking watersafety problems,a direct threat tohuman and animalsurvival.In recent years,although theinvestmentfund managementa lot ofHuaiheand other waters,but the effect is not obvious,the overall situationis still deteriorating.

在水安全方面，我国水污染问题十分严重，各地普遍存在着饮用水安全问题，直接威胁到人畜生存。近几年虽然投入大量的资金治理淮河等水域，但效果并不明显，整体情况仍在恶化。
