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 , coastlines--sensitive and _ 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 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... 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

It took me more than 10 years to realize that the world has no shortage of fashion designers who have the ability to make trendy and elegant garments, but that it is badly in need of, simply, clothes designers. My own definitions would set fashion and clothing greatly apart. It is a fact that, in the shopping malls, there are plenty of beautiful garments whose unpredictability makes our life color1ful and interesting. You are almost convinced: You can buy whatever you dare to think. There is no doubt that fashion designers are usually with high qualifications. They study fashion trends, select color1s, and make sure the final production of their designs is done properly. However, as experience grew with age, my attraction to arts became ever stronger. I have a strong desire for clothing to stand as does paint to the painter, as does stone to the sculptor, as a simple and particular language of an individual creation, which draws the audience from an appreciation of the surface to deeper thoughts with the world of the soul. I believe that the most meaningful creative motives should arise through caring for other people, the great care of humanity--a concern for human feeling and spirituality. _ , but it is bigger than love, and it is unconditional. I believe the greatest works of art can touch the deepest and strongest parts of human feelings and the world of the spirit, and only these works can be the memories of history, preserving the most valuable feelings that have ever existed, and inspiring a greater awareness of ourselves. I am not satisfied if people only appreciate clothing if it merely satisfies their desire. I believe clothing could be a specific creative language for communicating ideas and thoughts, for inspiring you and shaping your behavior. Those clothes fashioned out of necessity possess a power that can continue to exist across the ages. This is what I have tried to achieve, the clothing to return to its original simplicity, the clothing to help people regain the natural sense. The true... What is the main idea of the passage? A) Humanity is fundamental in fashion design. B) The growing fashion trends present human interest. C) Designers must concern for the desire of consumers. D) Fashion clothes have close relations with earth predictions.

Young children from poor families are more likely to consume junk food and fizzy drinks than their richer companions. A study of 1,800 four- and five-year-olds found more than half of those from poor backgrounds drank at least one a week, compared to just four in ten _ kids. They also drank less milk and consumed more fruit juice which is also linked to child obesity caused by high sugar intake . The phenomenon also relates to children who spend more than two hours a day in front of a TV or playing computer games--whatever their social circumstances. A companion study also found children from poor families were more likely to eat chips, sweets and chocolate. Professor Kate Storey said, "when you are looking at that age group, and such a large percentage of very young kids in the study are consuming a large amount of soda ,it is quite concerning. " The researchers carried out the study by surveying the parents of their participants to find out their dietary habits. Professor Storey said, "If you are drinking a lot of soda and fruit juice, they can displace consumption of water and milk, which are important not just for ending thirst, but for developing healthy bones and teeth, and health and wellness in general." Co-researcher Dr John Spence said, "Dietary behavior and intake patterns are influenced heavily by what happens in the first few years with children, and they maintain those patterns throughout childhood and into adolescence ." In addition to basic health education, this study identifies a need in how we are dealing with poverty and recognizing there is more to poverty than simply the number of dollars people have. Professor Storey said that shows how education can make a difference and lead to healthier eating habits, regardless of what is happening at home. "Many families live in places that might not be very healthy for them and, as a result, they make unhealthy food choices. You can start making a difference in different places. It calls for action in multiple settings, schools and communities,... What's the main idea of the passage? A) Young people like eating junk food. B) Junk food is bad for both young children and adults. C) Children from poor families are more likely to eat junk food. D) Junk food causes more and more children to become overweight.
