阅读题：A growing world population and the discoveries of science may alter this pattern of distribution in the future

Questions 31 to 35 are based on the following passage.

A growing world population and the discoveries of science may alter this pattern of distribution in the future. As men slowly learn to master diseases, control floods, prevent famines, and stop wars, fewer people die every year; and in consequence the population of the world is steadily increasing. In 1925 there were about 2,000 million people in the world; by the end of the century there may well be over 4,000 million.

When numbers rise the extra mouths must be fed. New lands must be brought under cultivation, or land already farmed made to yield larger crops. In some areas the accessible land is so intensively cultivated that it will be difficult to make it provide more food. In some areas the population is so dense that the land is parceled out in units too tiny to allow for much improvement in farming methods. Were a large part of this farming population drawn off into industrial occupations, the land might be farmed much more productively by modern methods.

There is now a race for science, technology, and industry to keep the output of food rising faster than the number of people to be fed. New strains of crops are being developed which will thrive in unfavorable climates: there are now farms beyond the Arctic Circle in Siberia and North America; irrigation and dry-farming methods bring arid lands under the plough, dams hold back the waters of great rivers to ensure water for the fields in all seasons and to provide electric power for new industries; industrial chemistry provides fertilizers to suit particular soils; aeroplanes spray crops to destroy locusts and many plant diseases. Every year some new means is devised to increase or to protect the food of the world.

31. The author says that the world population is growing because _____.

A) there are many rich valleys and fertile plains

B) the pattern of distribution is being altered

C) people are living longer

D) new land is being brought under cultivation

32. The author says that in densely populated areas the land might be more productively farmed if _____.

A) the plots were subdivided

B) a large part of the people moved to a different part of the country

C) industrial methods were used in farming

D) the units of land were made much larger

33. We are told that there are now farms beyond the Arctic Circle. This has been made possible by _____.

A) producing new strains of crops

B) irrigation and dry-farming methods

C) providing fertilizers

D) destroying pests and disease

34. Which of these words is nearest in meaning to the word "strains"？

A) types B) sizes

C) seeds D) harvests

35. The author's main purpose is to _____.

A) argue for a belief B) describe a phenomenon

C) entertain D) propose a conclusion

Population tends to grow at an exponential（指数的)rate. This means that they progressively

Population tends to grow at an exponential(指数的)rate. This means that they progressively double. As an example of this type of growth rate, take one penny and double every day for one month. After the first week, you would have only 64 cents, but after the fourth week you would have over a million dollars.

This helps explain why the population has come on "all of a sudden". It took from the beginning of human life to the year 1830 for the population of the earth to reach one billion. That repents(缓慢进行)a time span of at least two million years. Then it took from 1830 to 1930 for world population to reach 2 billion. The next billion was added by 1960, only thirty years, and in 1975 world population reached 4 billion, which is another billion people in only fifteen years.

World population is increasing at a rate of 9000 per hour, 220000 per day, and 80 million per year. This is not only due to higher birth rate, but to lower death rate as well. The number of births has not declined at the same rate as the number of deaths.

Some countries, such as Columbia, Thailand, Morocco, Costa Rica, and the Philippines, are doubling their population about every twenty-one years, with a growth rate of 3.3% a year or more. The United States is doubling its population about very eighty-seven years, with a rate of 0.8% per year. Every time a population doubles, the country involved needs twice as much of everything, including hospitals, schools, resources, food and medicines to care for its people. It is easy to see that this is very difficult to achieve for the more rapidly growing countries.

This passage chiefly discusses______.

A．the growth of world population

B．one type of the exponential rate

C．the population problem of more rapidly growing countries

D．the possible ways of dealing with the rapid population growth

阅读理解：Some of the world's most sign significant problems hit headlines. One example comes from agriculture

Questions 1 to 5 are based on the following passage.

Some of the world's most sign significant problems hit headlines. One example comes from agriculture. Food riots and hunger make news. But the trend lying behind these matters is rarely talked about. This is the decline in the growth in yields of some of the world's major crops. A new study by the University of Minnesota and McGill University in Montreal looks at where, and how far, this decline is occurring.

The authors take a vast number of data points for the four most important crops: rice, wheat, corn and soyabeans(大豆). They find that on between 24% and 39% of all harvested areas, the improvement in yields that took place before the 1980s slowed down in the 1990s and 2000s.

There are two worrying features of the slowdown. One is that it has been particularly sharp in the world's most populous(人口多的)countries, India and China. Their ability to feed themselves has been an important source of relative stability both within the countries and on world food markets. That self-sufficiency cannot be taken for granted if yields continue to slow down or reverse.

Second,yield growth has been lower in wheat and rice than in corn and soyabeans. This is problematic because wheat and rice are more important as foods, accounting for around half of all calories consumed. Corn and soyabeans are more important as feed grains. The authors note that "we have preferentially focused our crop improvement efforts on feeding animals and cars rather than on crops that feed people and are the basis of food security in much of the world."

The report qualifies the more optimistic findings of another new paper which suggests that the world will not have to dig up a lot more land for farming in order to feed 9 billion people in 2050, as the Food and Agriculture Organisation has argued.

Instead, it says, thanks to slowing population growth, land currently ploughed up for crops might be able to revert(回返)to forest or wilderness. This could happen. The trouble is that the forecast assumes continued improvements in yields, which may not actually happen.

1.What does the author try to draw attention to？

A.Food riots and hunger in the world.

B.The decline of the grain yield growth.

C.News headlines in the leading media.

D.The food supply in populous countries.

2.Why does the author mention India and China in particular？

A.Their self-sufficiency is vital to the stability of world food markets.

B.Their food yields have begun to decrease sharply in recent years.

C.Their big populations are causing worldwide concerns.

D.Their food self-sufficiency has been taken for granted.

3.What does the new study by the two universities say about recent crop improvement efforts？

A.They fail to produce the same remarkable results as before the 1980s.

B.They contribute a lot to the improvement of human food production.

C.They play a major role in guaranteeing the food security of the world.

D.they focus more on the increase of animal feed than human food grains.

4.What does the Food and Agriculture Organisation say about world food production in the coming decades？

A.The growing population will greatly increase the pressure on world food supplies.

B.The optimistic prediction about food production should be viewed with caution.

C.The slowdown of the growth in yields of major food crops will be reversed.

D.The world will be able to feed its population without increasing farmland.

5.How does the author view the argument of the Food and Agriculture Organisation？

A.It is built on the findings of a new study.

B.It is based on a doubtful assumption.

C.It is backed by strong evidence.

D.It is open to further discussion.

阅读短文，判断句子正误，正确的写T，错误的写F 。

In recent years, the Chinese auto industry has seen rapid growth, with the demand on private cars rising sharply in Chinese cities since 2002.

By 2009, China has replaced the U.S. to become the world's largest auto market. As an important part of the world car industry, the global auto industry will shift further to China. This brings historical opportunity to China's auto market.

Currently, both the development of China's auto market and the changes in consumer demand for vehicles are ever -increasing. China's auto industry will continue to grow in the next decade. It means there is still huge room for its development. China has an urban population of more than 600million. It also has a huge agricultural vehicle market in the rural areas. Hence, there is no doubt for China's development of auto industry. That is also the reason why the world's auto producers are paying more attention to the Chinese market.

()26. The demand on private cars increased greatly in Chinese cities since 2002.

()27. China has become the world's largest auto market.

()28. China's auto industry tends to decrease in the next decade.

()29. China has an urban population of less than 600 million.

()30. The reason why the world's auto producers are paying more attention to the Chinese market is that China's auto industry developed very quickly.

阅读理解：Across the rich world, welleducated people increasingly work longer than the lessskilled

Questions 1 to 5 are based on the following passage.

Across the rich world, well-educated people increasingly work longer than the less-skilled. Some 65% of American men aged 62-74 with a professional degree are in the workforce, compared with 32% of men with only a high-school certificate. This gap is part of a deepening divide between the well-educatedwell-off and the unskilled poor. Rapid technological advance has raised the incomes of the highly skilled while squeezing those of the unskilled. The consequences, for individuals and society, are profound.

The world is facing an astonishing rise in the of old people, and they will live longer than ever before. Over the next 20 years the global population of those aged 65 or more will almost double, from 600 million to 1.1 billion. The experience of the 20th century, when greater longevity(长寿)translated into more years in retirement rather than more years at work, has persuaded many observers that this shift will lead to slower economic growth, while the swelling ranks of pensioners will create government budget problems.

But the notion of a sharp division between the working young and the idle old misses a new trend, the growing gap between the skilled and the unskilled. Employment rates are failing among younger unskilled people, whereas older skilled folk are working longer.The divide is most extreme in America, where well-educated baby-boomers(二战后生育高峰期出生的美国人)areputting off retirement while many less-skilled younger people have abandoned policies that used Xto retire early. Rising life expectancy(预期生命),combined with the replace- Xpension plans with less generous defined-contribution ones, means that even the better-off must work longer to have a comfortable retirement. But the changing nature of work also plays a big role. Pay has risen sharply for the highly educated, and those people continue to reap rich rewards into old age because these days the educated elderly are more productive that the preceding generation. Technological charge may well reinforce that shift; the skills that complement computers, from management knowhow to creativity, do not necessarily decline with age.

1.What is happening in the workforce in rich countries？

A.Younger people are replacing the elderly.

B.Well-educated people tend to work longer.

C.Unemployment rates are rising year after year.

D.People with no collage degree do not easily find work.

2.What has helped deepen the divide between the well-off and the poor？

A.Longer life expectancies.

B.A rapid technological advance.

C.Profound changes in the workforce.

D.A growing number of the well-educated.

3.What do many observers predict in view of the experience of the experience of the 20th century？

A.Economic growth will slow down.

B.Government budgets will increase.

C.More people will try to pursue higher education.

D.There will be more competition in the job market.

4.What is the result of policy changes in European countries？

A.Unskilled workers may choose to retire early.

B.Morepeople have to receive in-service training.

C.Even wealthy people must work longer to live comfortably in retirement.

D.Peoplemay be able to enjoy generous defined-benefits from pension plans.

5.What is characteristic of work in the 21st century？

A.Computers will do more complicated work.

B.More will be the educated young.

C.Most jobs to be done will be creative ones.

D.Skills are highly valued regardless of age.

阅读理解：阅读下面的短文，根据文章内容进行判断，正确为“T”，错误为“F”。

The world’s longest high-speed railway route, running from Beijing to Guangzhou, has been in operation for a few years. It cuts travel time between the two cities from 22 hours to only 8 hours. With comfortable seats and quiet cabins, this high-speed line offers a pleasant journey for thousands of travelers.

The high speed railway connects Beijing with five provincial capitals. Part of the line, from Zhengzhou to Guangzhou, was in operation before the whole line was connected. The opening of the Beijing to Zhengzhou section has connected the entire line. It covers a total length of 2,298 kilometers.

The Beijing-Guangzhou line connects one third of China’s population and more than 40 percent of its economic power. Travelers benefit from the efficient network, and find that their hometowns are not that far away.

As the American publication _Newsweek_ puts itA、China is now engaged in a “railway revolution”. These 350 kilometer per hour high-speed railway trains have made the country’s vast territory “substantially smaller”, and changed the country economically.

阅读理解

阅读下面的文章，根据文章内容，完成相应的选择题。

EBOLA SURGE — 2014

The 2014 Ebola outbreak is the largest in history and the first Ebola outbreak in West Africa. Although the current epidemic does not cause a significant risk to other nations, many countries, including China and the United States of America, have actually been working closely with the Ebola hit states. For example, the US Centers for Disease Control and Prevention (CDC) is taking precautions at home besides its activities abroad.

CDC's team of “virus hunters” is supported by specialized public health teams both in West Africa and at the CDC Atlanta headquarters. Together, they offer continuous support to save lives and protect people. CDC works closely with a number of US government agencies, national and international partners. CDC's experience of working with Ebola is important to the World Health Organization's growing West Africa Ebola response.

On Sept. 2, 2014, CDC Director, Tom Frieden called for more international partners to join this effort. “The sooner the world comes together to help West Africa, the safer we all will be. We know how to stop this outbreak. There is a window of opportunity to do so — the challenge is to scale up the massive response needed to stop this outbreak.”

CDC's response to Ebola is the largest international outbreak response in CDC's history with over 100 disease specialists on the ground in West Africa, supported by hundreds of public health emergency response experts stateside, activated at Level 1, its highest level, because of the significance of this outbreak.

The CDC supports affected countries to establish Emergency Operations Centers at national and local levels and helps countries track the epidemic including using real-time data to improve realtime response.

Efforts in West Africa to identify those infected and track people who have come into contact with them are improving. The CDC is operating and supporting labs in the region to improve diagnosis and testing samples from people with suspected Ebola from around the world.

Local health care systems are strengthened through communication, coordination with partners and training on infection control for health care workers and safe patient treatment.
