Social media can be a powerful communication tool for employees, helping them to collaborate, share ideas and solve problems. Research has shown that 82% of employees think social media can improve work relationships and 60% believe it can support decision-making processes. These beliefs contribute to a majority of workers connecting with colleagues on social media, even during work hours.Employers typically worry that social media is a productivity killer; more than half of U.S. employers reportedly block access to social media at work. In my research with 277 employees of a healthcare organization I found these concerns to be misguided. Social media doesn't reduce productivity nearly as much as it kills employee retention (保留,保持).In the first part of the study I surveyed the employees about why and how they used platforms like Facebook, Twitter, or LinkedIn. Respondents were then asked about their work behaviors, including whether they felt motivated in their jobs and showed initiative at work. I found employees who engage in online social interactions with co-workers through social media blogs tend to be more motivated and come up with innovative ideas, But when employees interact with individuals outside the organization, they are less motivated and show less initiative.In the second part of the study I found 76% of employees using social media for work took an interest in other organizations they found on social media. When I examined how respondents expressed openness to new careers and employers, I found that they engaged in some key activities including researching new organizations and making new work connections.These findings present a dilemma for managers: employees using social media at work are more engaged and more productive, but they are also more likely to leave your company. Managers should implement solutions that neutralize the retention risk caused by social media.They can create social media groups in which employees will be more likely to collaborate and less likely to share withdrawal intentions or discussions about external job opportunities. Managers can also use social media to directly reduce turnover (跳槽) intentions, by recognizing employees’ accomplishments and giving visibility to employees’ success stories.( ) 1.What does previous research about social media reveal?A.Most employees think positively of it.B.It improves employees' work efficiency.C.It enables employees to form connections.D.Employees spend much of their work time on it.( ) 2.What did the author's own research find about social media?E.It influences employees' work negatively.F.It does much harm to employee loyalty.G.It kills employees' motivation for work.H.It affects employers' decision-making.( ) 3.What did the author find in his study about the effect of online social interactions?I.It differs from employee to employee.J.It tends to vary with the platform used.K.It has much to do with whom employees interact with.L.It is hard to measure when employees interact with outsiders.( ) 4.Whal docs the author suggest managers do to neutralize the retention risk?M.Give promotions to employees [or their accomplishments.N.Create opportunities for employees to share success stories.O.Acknowledge employees' achievements through social media.P.Encourage employees to increase their visibility on social media.

Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer sheet 2.The Price of Oil and the Price of Carbon[A] Fossil fuel prices are likely to stay “low for long”. Notwithstanding important recent progress in developing renewable fuel sources, low fossil fuel prices could discourage further innovation in, and adoption of, cleaner energy technologies. The result would be higher emissions of carbon dioxide and other greenhouse gases.[B] Policymakers should not allow low energy prices to derail the clean energy transition. Action to restore appropriate price incentives, notably through corrective carbon pricing, is urgently needed to lower the risk of irreversible and potentially devastating effects of climate change. That approach also offers fiscal benefits.[C] Oil prices have dropped by over 60% since June 2014. A commonly held view in the oil industry is that “the best cure for low oil prices is low oil prices”. The reasoning behind this saying is that low oil prices discourage investment in new production capacity, eventually shifting the oil supply curve backward and bringing prices back up as existing oil fields---which can be tapped at relatively low marginal cost----are depleted. In fact, in line with past experience, capital expenditure in the oil sector has dropped sharply in many producing countries, including the United States. The dynamic adjustment to low oil prices may, however, be different this time around.[D] Oil prices are expected to remain lower for longer. The advent of new technologies has added about 4.2 million barrels per day to the crude oil market, contributing to a global over-supply. In addition, other factors are putting downward pressure on oil prices: change in the strategic behavior of the Organization of Petroleum Exporting Countries, the projected increase in Iranian exports, the scaling-down of global demand (especially from emerging markets), the long-term drop in petroleum consumption in the United States, and some displacement of oil by substitutes. These likely persistent forces, like the growth of shale(页岩) oil, point to a “low for long” scenario. Futures markets, which show only a modest recovery of prices to around 60 a barrel by 2019, support this view.[E] Natural gas and coal—also fossil fuels—have similarly seen price declines that look to be long-lived. Coal and natural gas are mainly used for electricity generation, whereas oil is used mostly to power transportation, yet the prices of all these energy sources are linked. The North American shale gas boom has resulted in record low prices there. The recent discovery of the giant Zohr gas field off the Egyptian coast will eventually have impact on pricing in the Mediterranean region and Europe, and there is significant development potential in many other places, notably Argentina. Coal prices also are low, owing to over- supply and the scaling-down of demand, especially from China, which bums half of the world’s coal.[F] Technological innovations have unleashed the power of renewables such as wind, hydro, solar, and geothermal(地热). Even Africa and the Middle East, home to economies that are heavily dependent on fossil fuel exports, have enormous potential to develop renewables. For example, the United Arab Emirates has endorsed an ambitious target to draw 24% of its primary energy consumption from renewable sources by 2021.[G] Progress in the development of renewables could be fragile, however, if fossil fuel prices remain low for long. Renewables account for only a small share of global primary energy consumption, which is still dominated by fossil fuels—30% each for coal and oil, 25% for natural gas. But renewable energy will have to displace fossil fuels to a much greater extent in the future to avoid unacceptable climate risks.[H] Unfortunately, the current low prices for oil, gas, and coal may provide little incentive for research to find even cheaper substitutes for those fuels. There is strong evidence that both innovation and adoption of cleaner technology are strongly encouraged by higher fossil fuel prices. The same is true for new technologies for alleviating fossil fuel emissions.[I] The current low fossil fuel price environment will thus certainly delay the energy transition from fossil fuel to clean energy sources. Unless renewables become cheap enough that substantial carbon deposits are left underground for a very long time, if not forever, the planet will likely be exposed to potentially catastrophic climate risks.[J] Some climate impacts may already be discernible. For example, the United Nations Children’s Fund estimates that some 11 million children in Africa face hunger, disease, and water shortages as a result of the strongest El Nino(厄尔尼诺) weather phenomenon in decades. Many scientists believe that El Nino events, caused by warming in the Pacific, are becoming more intense as a result of climate change.C)Earning a competitive salary.
