六级作文人口增长与计划生育这篇作文条理清楚，语句通顺，尤其是过渡句的运用，值得推举。

The Expanding Population and the Birth Control The need for birth control methods has developed fairly recently, with the desire among many women to be able to deide when they want to have a baby. At the same time there is a growing awareness of the problem of a rapidly increasing world population.This problem of a rising world population is largely the result of improved medical skills, which have lowered the death rate and, at the same time, raised the birth rate by increasing live births and the number of babies who survive early childhood. There is a growing realization that food production cannot keep pace with these increases, the result of which is that in some countries people are already starving to death while many millions more suffer from malnutrition. This problem is further complicated by the fact that in places like America and Europe we obtain by trade and consume far more food and resources like oil than, say, the average Indian, thus leaving even less for the people in the underdeveloped areas to survive on.World population is rising at a rate of two per cent a year;this means an addition of 70 million people a year to the present population of more than 3,500 million. There arestrking regional differences in the population growth trends.The fastest growing region is Latin America which includes South and Central America and the Caribbean, while Africa and Asia closely follow Latin America. However, the largest absolute addition to the world population is in Asia which at present contains about three-fifths of the people of the world.。

人口过剩的英语作文篇1The 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 theconcerted efforts of all the parties concerned, we’re sure to solve the problem in the future.人口过剩的英语作文篇2Now the population of China is increasing, mainly because many people are unaware of this problem and have many children. For having one more child, I will be fined 30000 or 40000 yuan. You may want to do this because of the large population, isn't it good? I'll tell you about it.According to statistics, under the condition that all crops in our country have been harvested well without any loss, the food is only enough for 1.6 billion people. Although it is said that there are 1.3 billion people in China now, we don't know how many people there are actually. And now there are people who can't eat every day. Experts calculate that China's population will gradually decline after 30 years, but how many people will increase in 30 years. Besides, the whole country can feed six billion people without any loss of crops. Now there are droughts and floods. How much food will be lost. So although several children in a family have become lively, the overall situation is not good.The large population not only affects the food problem, but also affects the land. Our land in China is about the same size as that in the United States. But in some mountains in the United States, no one lives there, because people there can't walk on the steep mountains. But there are still people living in China under such bad conditions. They have to learn a skill since childhood, that is, hang a rope between two mountains, and then seize the rope to climb to another mountain to fetch water. If the middle can not support the fall, the valley is below, and the consequences can be imagined. This is the gap between ourcountry and the United States.Therefore, I think that a large population does have some advantages in some aspects, but it also brings many disadvantages to our country.人口过剩的英语作文篇3While the world population is aging and the population of developed countries is aging, China's population aging is also intensifying. The emergence of population aging is the result of social progress and economic development. China's population transformation Since the founding of the People's Republic of China, the death rate has dropped significantly and rapidly. The national fertility rate transformation began with the intervention of the national family planning policy in the early 1970s, and rapidly shifted from a high fertility level to a low fertility level. In this way, the aging of the population has led to the increasing burden of the labor force, affected the development of China's social economy, and put forward new requirements for the construction of the corresponding infrastructure, legal system and other material and spiritual aspects.In response to this situation, the National Commission on Aging issued the "Eleventh Five Year Plan" for the Development of China's Aging Cause, which proposed the goals and tasks to be achieved during the "Eleventh Five Year Plan" period, including medical security, social assistance, as well as infrastructure construction, elderly industry, and spiritual and cultural life of the elderly. We should not only correctly understand the causes, basic characteristics, development trends and possible socio-economic consequences of population aging in China, but also understand the impact of population aging on socio-economic operation and sustainable development. Only inthis way can we improve the scientific and feasibility of decision-making, solve the problem of population aging, and create a favorable population environment for the implementation of sustainable development strategies. By defining the scientific connotation of population aging, the causes of population aging in China are clarified. Through the research on the evolution process of population aging, this paper focuses on the characteristics of population aging in China and its impact on economy, society and family, and puts forward corresponding countermeasures to solve the problem of population aging.人口过剩的英语作文篇4In more and more developed countries, we have seen the following trend: With the increase of income, people begin to marry late and have children late. This result shows that the demographics have changed and people are getting older. Although it seems like a good thing to have more elderly people (such as their kindness and enthusiasm), no matter how much their intrinsic value is, it will have a serious impact on the economy and society.First, in order to increase a country's GDP, more products and services need to be produced every year. As the population ages and more people retire, fewer people are left to work and an economic gap is created. As a result, such countries have to rely on immigration to fill this vacancy, although this may work at some level, which will be an unsatisfactory solution. Secondly, as more people enter old age, they will face health problems, which will bring great pressure on medical and other social projects. In most countries, the government has to pay for at least some of the costs of medical care, let alone pensions, which means a lot of money to pay.It is short-sighted to only see the negative side. We should not directly impose anger on the elderly. The elderly can still make valuable contributions to society, whether it means helping to look after the third generation, working part-time or volunteering. From the individual level, the elderly are a real wealth.In short, the government should recognize the challenges posed by an aging society and take effective measures. But in addition to addressing the short-term impact of an aging society, the government should also take a long-term view and make every effort to achieve age balance in the future.人口过剩的英语作文篇5With a permanent population of 16.95 million, Beijing is the first city in China to gather 56 ethnic groups.Beijing, the capital, really reflects the national style and features. With its vast territory and dense population, its unique nature has attracted people from all ethnic groups, which is also a reflection of the inclusiveness of the Chinese nation.Of the more than 10 million people, I do not know how many are native Beijingers, but they must be few, fewer and fewer. Students from all over the country are trying their best to come to Beijing to study. After graduation, they have worn out their iron shoes to work in Beijing. After that, they have worked hard. If you buy a house in Beijing and get a Beijing hukou, you'd better have another Beijing son. As for those who did not squeeze into Beijing when they were young, they were also trying to cultivate a son who could go to Beijing to have a son. Of course, the above paragraph may be exaggerated, but it can really express the psychology of some people. They think Beijing is a treasure. It is a money tree and a symbol of glorifying our ancestors. Yes, whatwelfare does the country have to Beijing first, and what development does the country have to Beijing first. Because Beijing is the capital and the center of the country, and we don't know that we can't realize it, because we are Beijingers.人口过剩的英语作文篇6Many countries will experience an aging population in the next century due to declining birth rates and mortality. China will soon join them. According to statistics, China's aging population will approach its peak by the middle of the next century, accounting for 27 percent of the total population. 4%, percentage of people of age. This means that every four people will be old.Due to the aging problem, there are more and more facts about it, but most people are still ignorant of the problems brought by the increasingly serious problems. First of all, with the family becoming smaller, the pace of life continues to upgrade, and even more serious families take full care of the aged members. Secondly, aging leads to fewer people to support the relative decline of the working population of the elderly. Therefore, to some extent, it affects the productivity of the whole society. Third, and most importantly, China's aging population has led to the non synchronization of the successful implementation of family planning with the country's economic progress.The speed of population aging makes it urgent to take countermeasures. There is no doubt that their key is to build a solid economic foundation. At the same time, it should attach importance to the overall progress of society and change the backward situation in social security, welfare and services. More importantly, family health care and community services shouldalso be encouraged.人口过剩的英语作文篇7Population concentration, population flow and fertility enthusiasm are indicators of economic prosperity. Generally speaking, population concentration is a symbol of economic prosperity, and population loss is a manifestation of economic recession. The current difficulties in the northeast economy are largely due to the fact that the vicious circle of "economic recession - population outflow" has not been broken: the economic downturn has led to the loss of working age population and low fertility, and the lack of labor and talents has restricted economic development. Therefore, in order to fully revitalize the Northeast, we must rebuild the population ecology and optimize the population structure.Promote the formation of a virtuous circle of "economic development population agglomeration" through economic transformation. The direction of economic transformation in Northeast China is from a resource dependent economy to a knowledge economy focusing on innovation and relying on human capital, and a green economy focusing on ecological industries and relying on ecological resources. The innovative knowledge economy and the green economy of ecological and environmental protection can give people hope and confidence, enable the working age population and various talents to stay and attract, and form a virtuous circle of "economic development population agglomeration". To this end, we should further straighten out the relationship between the government and the market, focus on solving the problems of the government's direct allocation of resources, excessive and meticulous management, offside, vacancy and dislocation of functions, and optimize themarket environment; We will promote supply side structural reform, accelerate economic restructuring, and promote the healthy development of various enterprises; Innovate the system and mechanism, create an inclusive environment where all kinds of talents can make full use of their strengths, and make the fertile fields in the Northeast a place where dreams bloom like flowers.We will implement an active reproductive policy and optimize the population structure. We should rebuild the values of population and fertility, get rid of the traditional concept that population is a burden, and establish a positive concept that population is a resource and wealth. Adhere to the basic national policy of family planning, encourage a family to have two children according to local conditions, guide families to arrange births responsibly and in a planned way, and promote family happiness and balanced population development.人口过剩的英语作文篇8As is known to us,China has the biggest population in the world,which is more than 1,300,000, a large population causes some problems in cities,that's the many people gather in cities and the jobs are not graduates can't find a job though they have left school for addition,traffic jam is another problem resulting from the big e are too many cars on the roads and streets.The situation of the countryside is not many people live in the countryside and we don't have enough farm land for them.Fortunately,our government has realized the problems and has attached great importance to government is trying its best to create more jobs and improve traffic over,the one-child policy has helped a lot.人口过剩的英语作文篇9The aging population is going to become a major concern particularly in more developed countries, but this should not be viewed as something threatening to society. It is a blessing for any individual to live a long and healthy life, only that it could indicate that the responsibilities of caring for the elderly in the future may partly fall on the younger generation. The questions refer especially to how the younger generation could provide answers that are able to move society forward, taking into account a number of social and economic effects on the nation as a whole.As the proportion of older people is steadily increasing, there are doubts over changes regarding the structure of a modern society. A possible change may the distribution of years of expected lifespan on the social scale, now that the family planning program is in fashion. Then, what will this dramatic shift mean for social services, such as health caring and pension on retirement? Overall effects, however, are not clear enough; for instance, how older peoples prolonged lives are to be arranged in the social context? At this point, it is interesting to know how todays younger generation would re-think their roles in society if they might live 100 or more and be in good shape? And should working people in society continue to be retired as usual at 60 and 65 ?人口过剩的英语作文篇10The two charts give information about single-occupant households in England in the year 2011. The bar chart compares figures for occupants' age and gender, and the pie chart shows data about the number of bedrooms in these homes.Overall, females made up a higher proportion of people living alone than males, and this difference is particularlynoticeable in the older age categories. We can also see that the most common number of bedrooms in a single-occupant home was two.A significant majority of the people aged 65 or over who were living alone in England in 2011 were female. Women made up around 72% of single occupants aged 75 to 84, and 76% of those aged 85 or over. By contrast, among younger adults the figures for males were higher. For example, in the 35-49 age category, men accounted for nearly 65% of people living alone.In the same year, 35.4% of one-person households in England had two bedrooms, while one-bedroom and three-bedroom homes accounted for 28% and 29.8% of the total. Under 7% of single-occupant homes had four or more bedrooms.。

Lesson 8What to Do About GrandmaText AHal Bohlman, his wife Judy, and their three children live in a small apartment. Hal works in the income tax division of the government where he is a public information officer. Their children are now 12, 10 and 5 years old. Their plan is for Judy to return to work after their youngest child .starts elementary school next year.

In order to avoid inheritance taxes, her husband in his will left his estate to Judy with the provision that his wife would have use of it as long as she lived.Judy realizes that it would probably be dangerous for her mother to live alone.

However.this is only half the story. In the countryside there are no pensions and no free medical care for the aged. Many young couples are afraid that once they are old. there will he nobody to care for them. So they want a son who can tend them all their lives.If we raise more funds for the elderly in rural areas and build more sanatoriums and other institutions for them, the farmers can put their minds at rest.The majority of young couples nowadays are well educated even in the poverty-stricken areas.

出生率下降英语作文英文回答：The declining birth rate is a global phenomenon thathas been observed in many developed and developing countries. There are a number of factors that contribute to this decline, including:Economic factors: The cost of raising children is a major factor in the decision of whether or not to have children. In many countries, the cost of housing, education, and healthcare has risen significantly in recent years, making it more difficult for families to afford to have children.Social factors: The changing role of women in society has also contributed to the decline in birth rates. In many countries, women are increasingly entering the workforceand pursuing higher education. This has led to a decreasein the number of children that women have during theirlifetime.Cultural factors: In some cultures, there is a stigma associated with having children outside of marriage. This can lead to a decrease in the number of children that are born.Environmental factors: Concerns about the environmental impact of having children can also lead to a decrease in birth rates. Some people believe that having children contributes to climate change and other environmental problems.The declining birth rate has a number of consequences for society, including:Economic consequences: A declining birth rate can lead to a shortage of workers and a slowdown in economic growth. It can also lead to a decrease in the tax base, which can make it more difficult for governments to provide essential services.Social consequences: A declining birth rate can lead to a change in the age structure of society. As the number of older people increases, there will be a need for more healthcare and social services. It can also lead to a decrease in the number of young people, which can have a negative impact on the vitality of society.Environmental consequences: A declining birth rate can have a positive impact on the environment. With fewer people, there will be less demand for resources and less pollution.There are a number of things that can be done to address the declining birth rate, including:Providing financial assistance to families: Governments can provide financial assistance to families in the form of tax breaks, child care subsidies, and paid parental leave. This can help to reduce the cost of raising children and make it more affordable for families to have children.Promoting work-life balance: Governments and employers can also promote work-life balance by providing flexible work arrangements and paid parental leave. This can help to make it easier for women to have children and continue to work.Changing cultural attitudes: Changing cultural attitudes about having children can also help to increase birth rates. This can be done through public awareness campaigns and education programs.Addressing environmental concerns: Addressing environmental concerns can also help to increase birth rates. This can be done by investing in renewable energy and other sustainable technologies.中文回答：出生率下降是一个全球现象，在许多发达国家和发展中国家都有所观察。

Population and Birth Control(人口和控制生育)Population and Birth Control1. 由于人口的增长，2. 人类感到压力越来越大。

3. 控制人口增长是我国的基本国策。

4. 家庭子女多有许多弊病。

Mankind is feeling greater pressure from the expanding number of people. The area of the earth can never be expanded. Nor are there endless sources of food and clothing. Yet, the number of people is increasing be 80million each year. In the next fifty years, the world population may double. How can so many people be fed? What is worse, most likely, there will be a day when people can only have standing room.Birth control is a basic policy in our country. China has the greatest number of population in the world. Her level of per capita cultivated area ranks very low. With a high birth rate, the production of grain and other bare necessities will be unable to meet the needs of people. To raise people’s living standard, we must practice birth control.There are disadvantages of a family having more children. First of all, as the parents have only limited income in general, they cannot give their children a good upbringing in food, clothing and shelter, let alone education. Secondly, child rearing will exhaust the parents, leaving them no burden of the society so far as social morality and juvenile delinquency are concerned.人口和控制生育由于人口数量的增长，人类感到压力很大。
