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

The Internet has completely changed the workplace over the past three decades. Artificial Intelligence is now all set to do the same, and businesses that don't take advantage of the technology risk being left behind.

Global tech giants (巨头) like Amazon have been leading the change, and businesses of all sizes are now using the technology for employing and managing their staff.

Among them is L'Oreal. With about a million applicants for roughly 15,000 new positions each year, the company is using AI to hire.

“We really wanted to save time and focus more on quality, diversity and candidate experience. And AI solutions were the best way to go faster on these challenges, said Eva Azoulay, global vice-president of L'Oreal's Human Resources Department.

The company uses Mya, a chatbot, to save employers' time during the first stage of the process. It handles routine questions from candidates, and checks details such as availability and visa requirements. Should candidates make it to the next round, they’ll run into Seedlink, an AI software that scores applicants based on their answers to open-ended interview questions. These scores don't replace human judgment, said Azoulay, but they do pick out candidates who might not seem like obvious choices.

Early results have been promising. For one internship program, where 12,000 people apply for about 80 spots, employers claim they saved 200 hours of time while hiring the most diverse group to date.

Other businesses have gone beyond employment and are using AI to help manage employees. Some UK firms have started using Isaak, a system designed by the London-based company StatusToday, to track how many hours staff spend online and the number of emails they receive. London real estate agent JBrown has been using this system since March. CEO James Brown said it helps the firm understand employees' habits and prevent them from overworking. “It enables us to solve bottleneck problems and relieve overburdened employees,” he said.

Despite these examples of good practice, there is still a long way for AI to reach its full potential (潜力), and the technology comes with risks. Another AI danger could be its impact on jobs through automation (自动化). McKinsey predicts AI could add $13 trillion to the global economy by 2030, with early adopters doubling their cash flow over that period. But the demand for repetitive (重复的) or digitally-unskilled jobs could drop by around 10%, the consulting firm said in a 2018 report.

1.What can we learn about AI technology from Paragraph 1?

A.It causes a great problem in workplace.

B.It will replace the Internet in the future.

C.It requires businesses to invest much money.

D.It will become a necessary part of business.

2.L'Oreal uses AI in its hiring process to________.

A.pick out the most suitable candidates directly

B.come up with more questions unlimitedly

C.improve the company's hiring efficiency

D.save money by replacing human judgment

3.Firms with the system Isaak can_______.

A.prevent their employees from surfing the Internet

B.force their employees to form good working habits

C.monitor the contents of all their employees' emails

D.help their employees avoid being overstressed at work

4.The passage is mainly developed by _______.

A.setting examples

B.making comparisons

C.examining differences

D.following the time order

In the past decade the popularity of rock climbing has greatly increased, and so has the number of injuries. It has been estimated that rock climbing is now enjoyed by more than 9 million people in the US each year. Study findings revealed a 65% increase in the number of patients that were treated in US emergency departments for rock climbing-related injuries between 1991 and 2012.

The study, published in the online issue of the American Journal of Preventive Medicine, found that about 40,000 patients were treated in US emergency departments for rock climbing-related injuries between 1991 and 2012. The most common types of rock climbing –related injuries were fractures(骨折) and sprains （扭伤）。The ankle was the most common body part to be injured (40%). Climbers in the study ranged in age from 2 to 74, with an average age of 26. The study also found that women took up a quarter of the injuries.

Falls were the primary reason for injury with over three-quarters of the injuries occurring as the result of a fall. The severity of fall-related injuries had a lot to do with the height of the fall. Patients who were injured after falling from a height over 20 feet were 10 times more likely to be treated than patients who were injured falling from 20 feet or lower.

“We found that the climbers who fell from heights higher than 20 feet took up 70 percent of the patients treated for a rock climbing-related injury,” explained the study author Lara McKenzie, PhD, director at the Center for Injury Research and Policy at Nationwide Hospital. “This trend, combined with the fact that rock climbers have a higher hospitalization rate than other sports and recreational injuries, demonstrates the need to increase injury prevention efforts for climbers.”

1.Which body part is most likely to get injured for a climber ?

A. The arm　　　　　 B. The knee

C. The ankle　　　　 D. The hand

2.How many women climbers in American got injured while climbing a rock between 1991 and 2012 ？
