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

Over the last few years, nutritional trends have grown in numbers, as more and more people are becoming aware of the positive advantages that a healthy and balanced diet can have. So it should be no surprise that the phrase “clean eating” has been added to the Collins Dictionary. 1.
“Clean eating” is the trend that became popular over the Internet, especially among health and fitness fans. It is a type of diet where people avoid processed (加工过的) foods, such as bacon and white sugar. 2. No chemicals are used while growing organic foods, so they are kept in their natural state and are considered “clean”. Above all, “clean eating” encourages not only a more conscious type of eating, but also a lasting change in lifestyle, such as regular exercise.
The trend became more popular when the World Health Organization released its report on processed meat in 2015. 3. It links processed meats such as ham, bacon and sausages to cancer. And now many people are feeling anxious.
4. Dietitians(营养师) have noticed an increase in the number of women becoming weak and getting anemia(贫血). Some of these women are on a clean eating diet. They lack nutrients that come from some processed foods. Experts suggest eating a balanced diet of more “clean food” but also taking in a small amount of processed food. 5. It is necessary that people do not feel guilty(内疚的) if they sometimes have the food that may not belong to “clean food”.
A.But what exactly is clean eating?
B.But how is the phrase added to the dictionary?
C.Processed food made with organic ingredients become more popular.
D.Instead, people mostly eat plenty of fruits, vegetables and organic foods.
E.The report says eating processed food can be really harmful to a person’s health.
F.In addition, what is important is that the person has a healthy attitude toward foods.
G.Some people say clean eating helps control their weight and stay energetic, but not everyone thinks it is a great idea.

Two weeks after the opening ceremony, the Games are over. The last of the three hundred gold medals has been awarded and the flags of the winners have been raised for the last time.
The final event is the closing ceremony. This occasion is always sad and happy at the same time. It is a sad occasion because the tremendous excitement is over, and it will not happen again for four years. Those who have made friends will have to say goodbye, perhaps for ever. It is also a happy occasion because the competition is over and the athletes can really show their friendship for one another.
The closing ceremony is rather like the opening. But now the Olympic flame goes out and the Olympic flag, with its five rings, is lowered.

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.
