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.”

In the past decade, the use of social media has grown in a way that no one could have guessed. It has turned some teenagers into celebrities (名人) and turned the famous into the infamous, overnight.
A key feature of social media, however, is its volatility. Trends come and go, disappearing almost as quickly as they appeared. So, what were the key social media trends of 2018?
Short video apps such as TikTok and its Chinese equivalent Douyin, took the world by storm. The Telegraph reported that TikTok was ranked 8th on Apple’s App Store in April. And Douyin had more than 300 million domestic monthly active users in June, CNBC said.
Why are these short videos – which are rarely longer than a few minutes – so popular? Jiang Yige, Singapore-based analyst at FengHe Fund Management, has a theory. Short videos are “just right to fill in the little gaps in our busy schedules,” he told CNBC.
These videos – apart from being very convenient – are important to teenagers because they allow them to express themselves, according to Teen Vogue.
The sense of community that users of short video app get is another appealing feature. Liza Koshy, a user of the US app Musically who has over 2 million followers, said that she was thrilled when anyone said that her video had “inspired” them. “It’s really cool … because I think as social creators that’s what we all are,” she added.
Live streaming is another feature of our social media life that now seems as natural as sunrise. It’s a pretty neat idea: You can watch anyone, anywhere, live.
However, China has taken live streaming to a whole new level. In China, more than 100 million viewers monthly watch a live streaming video. Forbes thought that a number of factors had led to the popularity of live streams. Among them is viewers’ ability to interact while remaining anonymous.
However, the boom in social media may be having side effects too. Fake news is one serious problem it arguably causes. Material shared on these platforms is often not checked for accuracy. The most basic content can be false and can sway users one way or another. We use social media all the time; that doesn’t mean that we understand the influence it is having on us. We should be mindful of both the time we spend on it and its impact on our minds.
1.The underlined word “volatility” in Paragraph 2 possibly means “being _____”.
A.changeable B.steady
C.promising D.violent
2.According to Lisa Koshy, short videos are very popular because _____________.
A.they are very convenient
B.they help people kill time
C.they provide a sense of community
D.they allow people to express themselves
3.What can we learn about social media from the text?
A.The information from social media is highly reliable.
B.When it comes to social media, people know short videos the best.
C.People can’t communicate with each other without social media.
D.There is still much room for social media to make improvement.
4.What is the best title for the text?
A.Rapid Development of Social Media
B.Key Social Media Trends ruling 2018
C.Short Videos Taking the World by Storm
D.Live Streaming—New Feature of Social Media

In the past two decades，the Chinese economy has undergone many reforms in an effort to compete more effectively on the international market.These reforms included allowing foreign banks to offer credit cards to Chinese citizens.Now，researchers at the University of Missouri (MU) have found about 30 percent of Chinese urban households now own at least one credit card and the growth rate of credit card adoption has been an average of 40 percent per year between 2004 and 2009.
Rui Yao，an assistant professor of personal financial planning at MU，says that this large growth in such a small amount of time has positive and negative implications for the Chinese economy.
''With more and more people taking advantage of credit cards in China，it certainly increases potential consumer buying power，''Yao said.'' However，we found that more than 90 percent of credit card users were unaware of safety issues existing in credit card use and more than 60 percent had little knowledge of the consequences of credit card debt.This lack of knowledge could create problems as credit card ownership is expected to grow at a rate of 11 percent a year. ''
Yao found that while 72 percent of Chinese credit card holders were never late on their payment，only 55 percent were able to pay the full balance.She also found that 70 percent of Chinese credit card holders said that credit cards contributed to overspending.
Yao believes the Chinese could benefit from financial education designed to help them plan for their financial future and encouraging the Chinese to take advantage of debt in a responsible fashion is important for the Chinese economy. ''Appropriate use of debt can help households improve their quality of life as well as spur economic growth through an increase in market purchases'' Yao said.
1.Why did China allow foreign banks to offer credit cards to Chinese citizens?
A.To increase Chinese citizens’ confidence in economy.
B.To respond to the urgent demand for financial reforms.
C.To improve competitiveness in the international market.
D.To persuade more Chinese citizens to accept credit cards.
2.What is mainly talked about in Paragraph 3?
A.The potential market purchases in the future.
B.Weaknesses caused by lack of knowledge of credit cards.
C.The rapid growth in credit card ownership.
D.Advantages and disadvantages of using credit cards.
3.A lot of figures are used in the text in order to________.
A.record the valuable data B.provide concrete evidence
C.introduce a research method D.give a detailed description
4.The underlined word ''spur'' in the last paragraph is closest in meaning to ''________''.
A.control B.delay
C.promote D.discourage
