We can begin our discussion of “population as a global issue” with what most person mean when they discuss “ the population problem”: too many people on earth and a too rapid increase in the number added each year. The facts are not in dispute. It was quite right to employ a similar matter that linked demographic(人口统计学)growth to “ a long, thin power fuse that burns steadily from time to time until it finally reaches the limit, and explodes”.
To understand the current situation, which is characterized by rapid increases in population, it is necessary to understand the history of population trends. Rapid growth is a comparatively recent phenomenon. Looking back at the 8,000 years of demographic history. We find that population have been really stable or growing very slightly for most of human history. For most of our ancestors, life was hard, often nasty, and very short. For most of human history, it was seldom the case that one in ten persons would live past forty, where infancy and childhood were especially risky periods. Often, societies were in clear danger of extinction because death rates could exceed their birth rates. Thus, the population problem throughout most of history was how to prevent extinction of the human race.
This pattern is important to know. Not only does it put the current problems of demographic growth into a historical perspective, but it suggests that the cause of rapid increase in population in recent years is not a sudden enthusiasm for more children, but an improvement in the conditions that traditionally have caused high rate of death.
Demographic history can be divided into two major periods: a time of long, slow growth which extended from about 8000B.C. till approximately 1650 A.D. And a period of rapid growth since 1650. In the first period of some 9,600 years, the population increased form some 8 million to 500 million in 1650. Between 1650 and the present, the population has increased from 500 million to more than 4 billion. And it is estimated that by the year 2020 there will be 8 billion people throughout the world. One way to appreciate this dramatic difference in such abstract numbers is to reduce the time frame to something that is more manageable. Between 8000B.C. and 1650, an average of only 50,000 persons was being added annually to the world’s population each year. At present, this number is added very six hours. The increase is about 80,000,000 persons annually.
1.According to the passage, “population as a global issue” ____.
A. is quite unlike the population problem and thus doesn’t need our concern
B. focuses on tracking down the reason of rapid population growth
C. deals with the same problem aroused by the population problem
D. will manage the population growth problem from global perspectives
2.It can be inferred from the example of a power fuse that _____.
A. too much population will one day lead to the doom of human beings
B. the trend of population growth will keep unsteady until the destruction of Earth
C. demographic growth will follow a certain pattern of ups and downs
D. it is likely in the near future that population will reduce gradually
3.What leads to a stable growth of population for most of human history?
A. Species competition B. Low fertility C. Tribal fights D. High rate of death
4.The reason for a rapid growth of population lies in the fact that ______.
A. people are permitted to have more children
B. people can live better than before
C. newborn babies die less than before
D. we have found the secret of longevity
5.How many people are born every six hours at present, according to the author?

As our global population continues to rise, some assessments suggest it could reach nearly 10 billion people by 2050. To feed that many people, we will need to produce quantities of food.
With only 30 seasons of planting and harvest left before the population could hit that 10 billion figure, it’s clear that agriculture has to change, if we are to have any hope of feeding the planet.
Over the past six months I’ve travelled all over Europe speaking to pioneering scientists and engineers, global-thought leaders, and of course, knowledgeable farmers, for the BBC World News and BBC Future series, Follow the Food in order to examine issues around food supply and even find some potential solutions for our future.
One of the most shocking facts I learned is the amount of good and eatable food that gets wasted. According to the United Nations, “A third of all food produced ends up rotting (腐烂) in the dustbins of consumers and markets, or damaging due to poor transportation and harvesting practices.”
Spending time with farmers, producers, and consumers, I quickly saw how our current ways of growing, processing and selling food just aren’t sustainable (可持续的).
The only way we can feed 10 billion people by 2050 is if the farming and food industries become much more sustainable. And that requires changes to the whole model of growing, processing, transporting, storing and selling. It means a lot of businesses and governments need to take action. But so too do we all. Whether that’s going to the market and choosing the most “ugly” vegetables for dinner, encouraging supermarkets to change their labelling to show us the carbon footprint of our food, or using new tech to avoid waste, there’s so much we can do to value our food and its producers.
1.How does the writer feel about the production of enough food by 2050?
A.Optimistic. B.Impossible.
C.Challenging. D.Confident.
2.What is the purpose of the writer’s journey in Europe?
A.To experience various careers in Europe.
B.To have a knowledge of farmers.
C.To become the best host in BBC programs.
D.To make further studies of present situation.
3.What can be inferred from the statement of the United Nations?
A.Plenty of food waste is avoidable.
B.Food production is far from enough.
C.Advanced agriculture is urgently needed.
D.Foods are too fragile to be well stored.
4.What is the main idea of the last paragraph?
A.The procedure for food production is complex.
B.Joint efforts are needed to feed 10 billion people.
C.There are great opportunities for food business.
D.Governments should take full responsibility.

高三英语单项填空中等难度题查看答案及解析
As the world’s population continues to increase, so does the amount of global waste people produce. According to data collected by the World Bank Group, nations will generate 4 billion tons of waste annually by the year 2100. The pollution from trash is not only ruining the world’s oceans, air and soil but endangering all living creatures.
For years government agencies have been telling citizens to live a zero-waste lifestyle. Traditionally, manufacturers would make a product to be used and thrown by consumers. This linear model of production offered no help in the fight against global waste. Alternatively, a circular economy has been introduced. This is a system which aims to minimize waste and restore used materials. Once a product’s value is exhausted, the materials are recycled and returned to manufactures. The outcome is less waste.
In 2016, The Wall Street Journal reported on the Taiwan island’s recycling success rate in an article titled The World’s Geniuses of Garbage Disposal. In 1997, Taiwan established its signature 4-in-l Recycling Program, consisting of communities, recycling enterprises, government cleaning teams and the Recycling Fund. Residents separate their recyclable waste and bring it to their community’s recycling locations. The local government collection teams and private collectors collect it. Recycling companies buy waste materials from them to generate profits. Importers and manufacturers who are responsible for the recyclable products pay a fee into the Recycling Fund. The Recycling Fund is an essential aspect of the program used to subsidize (资助) the recycling disposal system, support education and research and development as well as finance recycling efforts in the future.
By following a circular system, more products than ever are being manufactured using recycled materials. For example, used tires can be recovered to pave roads, while plastic is reused to make new plastic products. And it also helps to conserve natural resources, reduce pollution, save landfill space and even create new job opportunities.
1.Why has a circular economy been introduced?
A.The population is on the rise.
B.It can help handle global waste.
C.The living creatures on earth are getting less diverse.
D.Traditional products are not environmentally friendly.
2.What can we learn about 4-in-l Recycle Program?
A.The recyclable materials can be collected officially or privately.
B.The importers and manufactures cover the costs of the program.
C.Recycling companies buy waste materials from the residents.
D.The government invests money as the recycling fund.
3.What’s the effect of the circular system?
A.It will cause no waste or pollution. B.It reduces the costs of the products.
C.It helps lower the unemployment rate. D.All the materials can be recycled again.
4.Which of the following does the text suggest?
A.Do nothing by halves. B.All that glisters isn’t gold.
C.Actions speak louder than words. D.One man’s trash is another man’s treasure.

Dear Editor,
Recently we have made a discussion about the prevent of global warming in our research
group. Everybody has become aware the green-house effect, what has drawn the attention of the world. Many scientists on the summit of COPENHAGEN warned any rise above 2 degrees could lead to a sea level rise threatening islands and coastal cities, kill off many specie of animals and plants. As a result of, every nation should work together to limit the release of carbon dioxide. Everybody should shoulder the responsible for fight against climate change, and a low carbon life is a must.
I think fight against global warming is part of environmental protection. If we humans are more friend to nature, nature will be friendly, too. It’s time everybody rethink our role in keeping peace with our mother, nature.
Yours sincerely,
Lihua
