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

Teenagers who drink alcohol are at higher risk of becoming victims of violence, a Cardiff University study has found.

A team from the School of Dentistry' s Violence Research Group studied drinking habits in

children aged | 1-16 in England. They found not only a link between drink and violence but also

that children who drank were more likely to be hit, even if they weren' t violent themselves.

The researchers are now calling for measures to prevent alcohol misuse to reduce injury

risk. Current policy focuses on reducing aggression but this research shows that there should be

equal effort to reduce victimization(受害).

More than 4,000 children were surveyed at 13 schools at four local authorities in the North, the Midlands, London, and the South. The study found that 25% of 1 l-year-olds were drinking

monthly and 3.6% daily, with 12.8% admitting to getting drunk 3 to 5 times a year. By the age

of 16, 40% were drinking weekly and 6.2% were drinking every day. The research also showed

22.6% of 16-year-olds were getting drunk more than 21 times a year.

The study, which has just been published in the Journal of Adolescence, found a strong

link between frequency of drinking and frequency of hitting other people.

However, children who reported drinking monthly were also three times more likely to be

hit. Adolescents(青少年) who drank but didn't get into fights were more likely to be hit than

those who did fight.

Professor Jonathan Shepherd, who led the research, said a lot of previous alcohol-related

violence work had focused on the offenders rather than the victims. His team is calling for more pre-vention work from parents and teachers in the first two years of secondary school by taking advantage of the "teachable moment", that is, immediately after a student has missed school because of drunkenness.

Previous work by Professor Jonathan Shepherd has shown drinkers may be more at risk of vio-lence because of reduced physical co-ordinatlon ( 配合), poor decision-making in threatening situa-tions and isolation while out late at night.

He said,"This new study seems to be the first to show a direct link between alcohol misuses and victimization. There now needs to be much more effort put into reducing alcohol misuse in order to reduce injury. "

58. The underlined word "aggression" in the third paragraph probably means_____

A. violence         B. sad feelings     C. bad manners          D. drunkenness

59. Drinkers may be more at risk of violence because of all the following EXCEPT __

A. reduced the physical co-ordination

B. isolation while out late at night

C. a higher frequency of hitting other people

D. poor decision-making in threatening situations

60. Which of the following statements is NOT true according to Professor Shepherd' s research?

A. The frequency of children getting drunk increases with age.

B. His previous alcohol-related violence work had focused on the offendersl

C. Some children missed school because of drunkenness.

D. This new study shows a direct link between alcohol misuse and victimization.

【小题1】According to the passage, the most dangerous place for city expansion is the _____.

D
Around half of all teenagers in the UK are putting themselves at risk of food poisoning because they don't wash their hands before eating or after visiting the toilet, a new survey indicates, To coincide with National Food Safety Week, researchers from the Food and Drink Federation (FDF) conducted a survey of over 500 people aged between 11 and 19 about their hygiene and eating habits. Their survey showed that 57 percent of teenagers admitted to not always washing their hands after visiting the toilet or before lunch at school. Of these, over two-thirds ate lunch, such as sandwiches or a burger, with their hands.
Furthermore, 40 percent of those who do wash their hands do not always use soap. And 75 percent said they dry their hands on their clothes when in a hurry—damp hands spread around 1,000 times more germs (病菌) than dry ones. Excuses that teenagers gave for not washing their hands ranged from not having enough time (24 percent) to dirty and unhygienic facilities (26 percent) and forgetfulness (22 percent).
Food safety expert Hugh Pennington, professor of Microbiology at Aberdeen University, said, "The best news about food safety is that one doesn't have to be a rocket scientist to do it properly. The had news is that even a simple and obvious thing like hand washing—which protects incredibly well—is seen by many people as good health theory, but not actually put into practice."
Martin Paterson, deputy director general of the FDF, said that teens' hygiene habits before eating were a recipe for disaster, adding that although most know how food poisoning could occur, the majority do not take simple measures to prevent it. "Of course teenagers don't want to be overprotected," he said, "but with up to 5.5 million cases of food poisoning a year, we clearly need to keep informing people of simple food hygiene messages in fun and imaginative ways, to remind people of all ages how they can continue to enjoy their food safely."

54．By saying "one doesn't have to be a rocket scientist to do it properly" (Para. 3), Hugh Pennington means "____".
A．it isn't necessary to go to outer space to practice food safety
B．practicing food safety isn't as important as space exploration
C．it's not a must to practice food safety
D．practicing food safety isn't terribly difficult
55．Educated about food poisoning, most teenagers      .
A．still get food poisoning at least once a year
B．still fail to take simple measures to avoid it
C．are able to avoid food poisoning
D．are concerned about their food safety
56．What is the main message conveyed in the text?
