The rapid growth of cities worldwide over the next two decades will cause significant risks to people and the global environment, according to analysis.
Researches from Yale and Stanford predict that by 2030 urban areas will expand by 590,000 square miles—nearly the size of Mongolia—to meet the needs of 1.47 billion more people living in urban areas.
“It is likely that these cities are going to be developed in places that are the most biologically diverse,” said Karen Seto, a famous scientist at Yale University. “They are going to be growing and expanding into forests, biological hotspots, savannas(热带稀缺大草原), coastlines—sensitive and vulnerable places.”
Urban areas, they found, have been expanding more rapidly along coasts. “Of all the places for cities to grow, coasts are the most sensitive. People and buildings along the coast are at risk of flooding and other environmental disasters,” said Seto.
The study provides the first estimate of how fast urban areas globally are growing and how fast they may grow in the future. “We know a lot about global patterns of urban population growth, but we know significantly less about how urban areas are changing,” she said. “Changes in land cover associated with urbanization lead to many environmental changes, from habitats loss and agricultural land conversion(转化) to changes in local and regional climate.”
The researchers examined studies that used satellite data to map urban growth and found that from 1970 to 2000 the world’s urban footprint had grown by at least 22,400 square miles—half the size of Ohio.
“This number is numerous, but, in actuality, urban land expansion has been far greater than what our analysis shows because we only looked at the published studies that used satellite data,” said Seto. “We found that 48 of the most populated urban areas have been studied using satellite data, with findings in journals. This means that we’re not tracking the physical expansion of more than half of the world’s largest cities.”
Half of urban land expansion in China is driven by a rising middle class, whereas the size of cities in India and Africa is driven primarily by population growth. “Rising incomes translate into rising demand for bigger homes and more land for urban development, which has a great effect on biodiversity conservations, loss of carbon sinks and energy use.”
1.According to the passage, the most dangerous place for city expansion is the _____.
A．forest B．desert C．savannas D．coastline
2.The underlined word “vulnerable” (in Para. 3) probably means “____”.
A．diverse in plants B．beautiful in scenery
C．easily damaged D．very productive
3.From Para. 5, we can infer that ____.
A．urbanization is a good way to improve people’s standards of living
B．cities develop very fast and more and more people come to live in cities
C．more and more agricultural farmlands are used to make room for local animals
D．in the past, researchers focused their attention on the expanding urban areas
4.Cities in Africa become bigger and bigger mainly because of their ____.
A．growing population B．rising middle class
C．unique living patterns D．economic development

高一英语单项填空简单题查看答案及解析
Over the last two decades (十年), the Earth has seen an increase in vegetation (植被) and China and India are leading the increase in greening on land. The result comes mostly from tree planting programs in China and intensive agriculture(集约农业) in both countries.
Researchers from Boston University found that global green area has increased by 5% since the early 2000s, an area equal to the size of Amazon rainforest. Among the increased area, China and India contribute to about 33%, especially China, with 25% itself. China’s great contribution came mostly from its programs to protect and expand forests, which is about 42%. These programs were developed in an effort to reduce the effect of desertification, air pollution and climate change.
Another 32% of the greening change in China, and 82% in India, resulted from intensive agriculture of food crops. The land area used to grow crops in China and India has not changed much since the early 2000s. Yet both countries have greatly increased the total green area and food production in order to feed large populations. The lead author Chi Chen of Boston University said,
“That is a surprising finding, since it is generally believed that land degradation(退化) in populous countries is usually more serious.”
Rama Nemani, a research scientist at NASA’s Ames Research Center, saw a positive message in the new findings. “Once people realize there is a problem, they tend to fix it,” However, the researchers rang bells as well. They pointed out that the gain did not necessarily fill up the loss of natural vegetation in tropical regions like Brazil and Indonesia.
1.What’s the first paragraph mainly about?
A.The earth is becoming a green land.
B.China and India are forest countries.
C.China and India matter in greening the Earth.
D.China and India develop intensive agriculture well.
2.Why is Amazon rainforest mentioned in Paragraph 2?
A.To show its importance to the planet.
B.To call on people to protect rainforests.
C.To clearly show the increased green area.
D.To be evidence of the lost natural vegetation.
3.What benefits can China’s tree planting programs bring?
① Reducing air pollution.
② Increasing rich land for crops.
③ Helping with climate control.
④ Controlling the desertification.
A.①②③ B.①③④
C.①②④ D.②③④
4.What can we infer from the last paragraph?
A.Brazil and Indonesia do not protect their forests.
B.The findings discouraged belief of a green world.
C.Humans are creative enough to solve all problems.
D.More efforts are needed to protect natural vegetation.
5.Where does the text probably come from?
A.A newspaper. B.A travel brochure.
C.An interview. D.A geography textbook.

Over the past 40 years, China has helped more than 700 million rural residents out of being poor, and the poverty rate — the proportion of people living below the Chinese poverty line — had fallen among the rural population from 97.5 percent in 1978 to 3.1 percent at the end of 2017, official figures shows. China’s achievements in poverty alleviation (扶贫) made the world look at China with admiration.
“For me, it is unbelievable that over 40 years, that is, over the course of one working lifetime, China has gone from one of the poorest countries in the world to one that is about to eliminate(消除) absolute poverty,” said Craig Allen, president of the US-China Business Council.
Varaprasad Sekhar Dolla, a professor of Chinese studies at India’s Jawaharlal Nehru University, also spoke highly of China’s achievements in poverty reduction. “If global poverty came down greatly in the last three or four decades, it’s partly because of the Chinese contribution to reducing poverty within its own national boundaries,” said the Indian scholar.
In the eyes of Khairy Tourk, a professor of economics with the Stuart School of Business at the Illinois Institute of Technology in Chicago, “many countries look up to China to learn from its experience.” “The Chinese experience is based on building a modern infrastructure (基础设施) and then on setting up special economic zones that would help underdeveloped countries to become more industrial,” he added.
In the government work report delivered at the opening of the annual NPC session (全国人大会议) on March 5, China promises to reduce its population of rural poor by over 10 million this year.
1.What’s the purpose of the numbers given in the first paragraph?
A.To show China has helped many rural residents out of poverty.
B.To imply many Chinese are suffering from poverty.
C.To show the great changes of China in the past 40 decades.
D.To indicate all Chinese will eliminate poverty this year.
2.What’s the attitude of Craig Allen to China’s achievements in poverty alleviation?
A.surprised. B.interested. C.upset. D.indifferent.
3.Which is the meaning of the underlined sentence in Paragraph 3?
A.The global poverty has come down except China.
B.China should try its best to help the world out of poverty.
C.China has made great contributions to world poverty alleviation.
D.China has eliminated poverty completely.
4.What does the passage mainly talk about?
A.China will make more progress in poverty alleviation.
B.China has done a lot in poverty alleviation.
C.China has realized its dream to help its people out of poverty.
D.The world speak well of China’s achievements in poverty alleviation.
