关于交通问题的中考英语作文

With more and more cars coming into our families, we are happy that it has greatly improved our life. But unluckily, it has also brought many problems, such as heavy traffic and traffic accidents.

Traffic safety is everybodys business. We must obey the rules. For example, we must walk on walk side, when we cross zebra – crossing, stop and look right and left, then go across fast. Dont play football on the road .we can tell our parents not to drink before they drive, not to run through red lights, not to talk and laugh while driving etc.

We can say cars are coming into our life, but only when everybody thinks traffic safety is everybodys business can we be safe driving on roads and walking on sidewalks.

交通安全人人有责。我们必须遵守规定!例如，我们必须走在一边，当我们过斑马线，停下来，看左，右，然后跨越快速。不要在马路上踢足球，我们可以告诉父母开车前不要喝酒，不要闯红灯，开车时不要说话和笑。

我们可以说汽车正在进入我们的生活，但只有当每个人都认为交通安全是每个人的业务，我们可以安全驾驶道路和人行道上行走。

环境问题 英语作文【1】

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.

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?

Recently,fog and haze has become a imminent threat which most northerners in China are facing.

While the cities of China have greeted striking speed of development with open arms,they suffer greatly from a persistent and dense haze of pollution and smog.

It is high time that we took some methods to protect the environment and ourselves.

Generally speaking,there are three effective ways.

First of all,the government should take into serious consideration the emergency and severity of the air pollution,and take measure to deal with it.

Such as more public transportation systems should be put in use,more energy-saving resources should be utilized.

What’s more,every little effort from individuals counts.

The citizens should contribute to the reduction of pollution by driving less.

Last but not least,try to reduce the time of outdoor activities,especially when the air quality is not good enough.

From what has been mentioned above, to protect our air,we must keep in mind that whatever we give out,we take back in the long run.

So we have to drive less,pollute less and make more changes.

The pictures symbolically illustrate pollution is becoming increasingly serious around the globe. In the first cartoon， a man is scorching the earth on a chimney. In the second one， a famous ancient Chinese poet， Wang Bo is astonished by the heavy smoke poured by chimneys into the air and dirty river polluted by a factory. We are informed that “the autumn river is the same color with the sky”。

The drawer is sending a message about the significance of the need for everyone to fight against the danger of environmental pollution. There is no denying that the industry is indications of civilization， proGREss and development. Unfortunately， as industry develops， so will the number of factories， and the amount of industry pollutants. We are so development-oriented that we almost can sacrifice our blue sky and pure water in order to obtain a little material gain.

As a consequence， it is imperative for us to take drastic actions. On the one hand， the factories should be equipped with devices which can dispose of waste gas and water so as to prevent them from polluting our planet. On the other hand， there should be an increasingly loud voice from the public for firm actions against poisonous gas sent off and unhealthy water polluted by factories.

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。

The large number of our population has become one of the most serious problems of our society. According to a recent survey of the National Bureau of Statistics, there are more than 1.3 billion people in our country, which account for about 1/5 of all the people in the world. The same survey also predicts that our population will grow quickly in the years to come.

Overpopulation has brought about a series of negative effects to our economic development and social security. In the first place, too many people impose a heavy burden on our environment. As a result, we suffer from a shortage of fresh water and natural resources. In the second place, as the supply of labor greatly exceeds the demand of the society, many people become employed. This is a source of social unrest. Last but not least, we have to manufacture all kinds of products to meet the needs of the people, which causes environment pollution to our lakes and land.

Serious though the problem seems, we have to take some measures to tackle it. On the one hand, the government should carry out more strictly the policy of family planning, thus reducing the total number of population. On the other hand, all the people should realize the harms of overpopulation. With the concerted efforts of all the parties concerned, we’re sure to solve the problem in the future.

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.

Bathed in bright sunshine and beautiful our dear alma mater. Teachers of students walked hurriedly, but also with a dew of the flowers will be contests ... ... constitute a campus landscape plan.

In this piece of great vitality, you can imagine how it used to be like?

Without an advanced multi-media platform, class, chalk dust from time to time will "drill" into your nose so that you can not help to play a big sneeze. But if you came to my school, there will always surprise you.

Came to the school gate, the first thing you see should the number of those few characters in red: the new North River Primary School. Look, in the sunshine, then a few shiny plaque, giving a pleasant feeling.

Continue to move forward, the most striking place is the fountain of Nazuo! Peaks rising one after another like a layer upon layer of the water column, which also has a colorful statue; a few naughty cute bird flaps helplessly fledgling wings, eyes filled with not only ignorance, but also looking forward, eager to fly vast blue sky.

In the fountain to the left, has a small flower bed. Where trees, flowers, dew on the petals of a flower child in the colorful jumping, rolling; delicate green and yellow earth lightly stroked the earth, Feng ER blown it joyfully dancing, singing ... ... see, big tree Ficus are so tall and straight, head held high, Look East from time to time, as if thinking about our greatest respect.

Continue to move forward, it is our playground. Every day, everyone in a vigorous manner the students exercise, vowed to have a strong physique, in order to serve the motherland. Well, two students were running the plastic on the runway. See this scene, I could not help think: Three years ago, the school using a cinder track, running up and dust ... ... Until now, our school put on the plastic track, that we can best play the best level of ... ...

The first fifty years of the next millennium will be critical for the worlds population. By 2050 population growth should have leveled off, but by then well have 10 billion people--two-thirds as many again as we have today.The rate of population growth is something we can choose right now, though: its not something that just happens, but a matter of human choice. The choice is a complicated one,with many variables, but it remains a choice.

If we want to prevent a population explosion, we should take action now -or assist the poorer countries to do so. They need better government, better institutions, better labor and capital markets, better schools.

Anything that increases the value of womens time and adds to the cost of caring for a child makes a woman less likely to have that child. Since big families are often seen as safety nets for illness and old age, improving poor peoples access to insurance, pensions and welfare institutions also has a major impact. This can be as simple as rural credit, providing a means of saving. Finally, there is education--both for women and, perhaps even more important, for the next generation of children.

These steps are there to be taken, but there appear to be some countries that are not seriously trying at the moment. If we cannot achieve that we will certainly not control population.

That said, I dont feel pessimistic that we are going to run out of resources: we are becoming more efficient at producing food faster than the rate at which population is increasing. There is, however, a risk that we will wreck the environment so effectively that the world will no longer be an attractive place to live. That really would be a dismal outcome, to reach world population equilibrium only to find wed destroyed the natural environment in the process.

第一个五十年的下一年世界人口将至关重要。到2050年人口增长应该趋于平稳,但那时我们将有100亿人——我们今天三分之二尽可能多的再次。人口的增长是我们可以选择现在,尽管:这不是刚好,但人类选择的问题。选择是一个复杂的,有许多变量,但它仍然是一个选择。

如果我们想避免人口爆炸,我们现在应该采取行动或者帮助贫穷国家。他们需要更好的政府,更好的制度,更好的劳动力和资本市场,更好的学校。

任何增加的价值,女性的时间和增加了的成本照顾一个孩子会让一个女人更不可能有孩子。自大家庭往往被视为安全网疾病和衰老,改善贫困人口获得保险、退休金和福利机构也有重大影响。这可以简单如农村信用,提供储蓄的一种手段。最后,还有教育,对于女性来说,也许更重要的是,对于下一代的孩子。

有采取这些步骤,但似乎有些国家不认真努力。如果我们不能实现,我们将肯定不是控制人口。

说,我不觉得悲观,我们将耗尽资源:我们正变得更有效地生产粮食的速度比人口增长的速度。然而,风险,我们将有效地破坏环境,世界将不再是一个吸引人居住的地方。这确实是一个可悲的结果,实现了人口的平衡却发现在这个过程中我们破坏了自然环境。

The line chart depicts that the percentage of those aged over 60 increased moderately from 6% of the total population in 1990 to 15% in 2010 in China. It is predicted that the proportion will amount to 25% in 2020 and 30% in 2040.

Quite a few factors can account for this phenomenon, but the following might be the critical ones: for one thing, with the implementation of Chinas family planning policy and the improvement of peoples living standard, fewer and fewer people are willing to have more children. Therefore, the birth rate has dramatically dropped, which results in a low proportion of youngsters and a higher proportion of elders. For another, due to the fact that more hospitals are equipped with advanced medical instruments and more professional staffs, many incurable diseases now can be easily cured. As a result, the public can enjoy an increased life span, adding to the growing proportion of old people.

The aging of the population is also a result of social progress and economic development. However, this phenomenon will be likely to bring about some undesirable consequences in the future. Hence it is high time that we figured out some ways to face the up-coming challenges.

作为一种公共交通工具，共享单车能够有效地解决“最后一公里”的出行问题，在一些交通拥堵的大城市，共享单车让许多人享受了有品质的出行。

然而我们在路边，在小区内，经常发生和发现共享单车残缺不齐的怪相。共享单车频遭霸占、破坏的事实，说明了新事物的超常规发展，往往会暴露基础的薄弱。暴露和反映出我们在公民素养和公德教育上还有薄弱环节。共享是“使用而非拥有”，共享的前提是对他人权利的承认和尊重。权利意识和诚信意识，是共享经济得以充分发展的观念根基，法治文化和诚信文化是共享经济繁荣发展的文化土壤。如果忽视了思想文化的土壤培育，共享经济的发展就会成为沙上建塔，共享单车的单兵推进就会夭折。这才是应对共享单车发展难题最需要直面的问题。这也说明了新事物的超常规发展，往往会暴露基础的薄弱。共享单车，我们可能还没做好公民素养与公德教育上的准备。

作为文明城市和文明市民，共享单车就是一面照妖镜，照出了我们城市管理的短板和市民素质的严重不足。作为管理者，主动引导和加强市民文明素质教育，是坚持科学发展观，实现经济社会协调发展的需要。即在促进经济社会发展过程中，不仅要满足人民群众日益增长的物质需求，还要努力满足人民群众日益增长的精神文化需求。

加强市民文明素质教育，是优化发展环境，加快文明建设发展的需要。只有市民素质提高了，文明形象提升了，才能为经济发展和社会进步创造良好的环境。

加强市民文明素质教育，是改善人居环境，提高市民生活质量的需要。市民素质高低决定城镇文明的发展水平，没有市民素质的普遍提高，经济的发展、社会的稳定、文化的繁荣、环境的优美都无法实现，更不可能持续。

“发展的列车匆匆驶过精神的站台，现实的变化把心灵的地图抛在身外” 。制度的疏漏可以迅速补上，文化的短板却需要久久为功下恒心、春风化雨做细活。清除陈旧的观念、病态的积习，让法治理念、诚信意识成为更多的公民、特别是孩子的思想基因，不仅是为共享经济铺路，更是为推进和谐中国奠基

人口问题是当今世界上最大的问题之一，中国是世界上人口最多的国家，如果人口增长过快，将会带来许多严重问题，我们应控制人口增长。

China has a huge population, so the population of china will be very hard to control. Many specialists to solve this problem, but no one have a good

way to solve. Now, the population of china have about 1.3 billion population, and land holdings per head average only 0.82 hectares, also the plough holdings per head average only 0.106 hectares. It take up 43% of the world, so that means the resource of our country is very less now, and didnt surpass the half percentage of the world.

In this article, I will show you some information about the Chinese population policy.

The history of Chinese policy

Start with 1949, china was liberate. The leader of china Mao Zedong was make a policy which is encourage people to bear, because the Mao think a strong country need a huge population. So, in that time if a woman burn many children, then the woman will called “hero woman”.

And many people were born, that is why the population of china were very huge new.

In 1978, the family plan were start to use, because the population of china is too huge, and need some policy to control it. So Chinese government was start to use the family planning to control, that is the most useful way to control, they do many thing like welfare to the Chinese people.

At that time, many of the population were like thispolicy, because they can get much benefit from this event.

I have seen some poster of the family planning in 1978, and I think it is fool the common people in that time. So I always pity for all elderly Chinese

people, and my parent tell me it was very cruel that time. When you born more than one child, you will have much and much punishment from the government, like to injure your house, increase your tax levy, but not cruel as kill you, so Chinese is very kind that time!

Now, the government have been thinking the problem of the population, some peoplesay that we have been keeping the family planning, and other people think we have to stop the family, so it have two choose of family planning, each of it will have a big change in china.

Family planning

Family planning is a kind of population policy in the world which is very common, many country were use this policy to control the population, because it is very easy to use, and very convenient to manage the population. Also is very low-cost to use.

But it have some bad way, like it will have a big problem called aging of population, it made the many young peoples burden very huge, very hard to care two parent or more.

Conclude, family planning isnt the best way to control the population, and it can bring many problem to the country. But we cant find another way to control the population, so we just can use this policy.

The policy of population now

One Chinese leader of family planning department said that we have to keep going for family planning forever, and china need much and much strict family planning to control our population.

Then many specialist to publish their own idea of family planning, all of

ideas were talk about to weaken or stop the family planning, and give some advice of population. Here I would like introduce some specialist ideas.

Chinese population is very large now, if we stop growing immediately, it will have a big problem call aging of population. If this problem happen, the young people will be very hard to provide their family.

Population will be stop growing to 1.8 milliard if we dont do anything, so that is a good way to control the population and dont have much shortcoming. It can be a better way to control the population, isnt it

If we still using the policy of family planning, it will have a large population decrease, and will have aneffect of many thing. Productivity of china will be less, and manpower resource will be less too.

This is all my thinking

It has been estimated that a thousand years ago there were less than 400 million people on earth. Today, however, the worlds population has amounted to 5,000 million. What is worse, it keeps growing at a surprising speed. If this trend continues, the worlds population will shoot up to 7,000 million by the year 2000. This is what we call population explosion.

The rapid development of science and technology is the main cause of population explosion. We can see that the population has been growing at a tremendous speed since the Industrial and Agriculture Revolution in 1650, which raised the peoples standard of living, and the emergence of modern medicine in 1550, which lowered the peoples death rate.

Population explosion will result in a lot of such problems as food shortage, housing shortage and unemployment. It is time that we acted quickly to carry out the policy of birth control otherwise, mans survival on the earth will be threatened.

科学技术的迅速发展是人口爆炸的主要原因。我们看到，自1650工农业革命以来，人口数量以惊人的速度增长，人民的生活水平提高了，现代医学的出现在1550，人民的死亡率下降了。

Since the development of the technology, the society gets modernized, people make use of the high technology to pursue more profit. Though the government has noticed the problem that people do to the environment, they still can’t prevent negative result that the polluted environment brings.

Many years ago, the most prominent problem of the polluted environment is that the river and the water were changed their color, some fish even died for the polluted river. Now the situation becomes ever worse, lately, in the big city, like Beijing and Shanghai, people are annoyed by the bad weather. It is not the rainy day, but the haze around the sky, there is no way for people to run away for it. The haze contains toxic elements, people breathe it and hurt their bodies.

The haze problem is the result of people’s pursuit for the profit, what people did to the environment now has been paid back by the environment. Now people have realized the revenge from the nature is so huge, protecting the environment is the main task.

Environmental Protection No one，regardless of race, religion or nationality, can deny that the world we live in is becoming increasingly intolerable because of the effects of global warming. According to many experts, even greater impacts are still on the way. There are numerous causes for this problem. On one hand, human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming according to the theory. On the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem. It is urgent that immediate and effective actions should be taken right away. First, more trees need to be planted to help improve and beautify the environment. Besides, stricter laws concerning global warming and irresponsible use of fuel resources have to be put into effect and achieved good results. In a word, there is a long way to go before we can take a comfortable world for granted again .

Population officials and demographers have much to worry about China’s increasingly aging population. It is estimated that the proportion of people aged 60 or older in China will rise to 11.8 percent in 2020. By the middle of this century, people aged beyond 60 will take up 27.4 percent of the total population — that means one out of every four people will be senior!

The aging population poses a serious challenge to families and the society. On the one hand, with families becoming smaller and living pace escalating, it is even graver for families to care for aged members adequately. On the other hand, aging causes a relative decline in working force. Consequently, the productivity of the whole society will be affected to some extent.

The rapidity of the population’s aging has made it more urgent for the adoption of countermeasures. There is no doubt that the key is to build a solid economic foundation. Meanwhile, importance should be attached to overall social progress by changing the backward situation in social security, welfare and service. What’s more, family care and community-based services should also be encouraged.

[考博英语作文23：人口增长、 人口质量

China has become a country with an increasing number of old people. By old people we usually mean persons over the age of sixty. We often call them senior citizens instead of old men to show our respect.

Most senior citizens retire or no longer work full-time. They usually live in their own houses not far from their childrens, while the children of a few senior citizens have gone abroad and work or study far beyond the oceans. For certain senior citizens, tile years after retirement are not very enjoyable. First, they feel that their lives lose meaning for being at home all day. In addition, they may feel lonely, especially those without children around. Moreover, they become more concerned with their health, as they grow older, and worry a lot about their safety. At the same time, many senior citizens enjoy their lives. They feel free to do things they were not able to do when they were working and raising their families. They spend their time travelling, doing exercises or watching TV. They get together with their fellow members who have the common interests and equal free time.

In fact, there are some still continuing their work, not just for money, but to show their value. However, no one really wants to be old, and perhaps all like to be young forever.
