After becoming president of Purdue University in 2013, Mitch Daniels asked the faculty

17、to prove that their students have actually achieved one of higher educations most important goals: critical thinking skills. Two years before, a nationwide study of college graduates had shown that more than a third hadmade no (26)_ gains in such mental abilities during their school years. Mr. Danie

18、ls needed to(27)_ the high cost of attending Purdue to its students and their families. After all, the percentageof Americans who say a college degree is “very important” has fallen (28)_ in the last 5-6 years. Purdue now has a pilot test to assess students critical thinking skills. Yet like many co

19、llege teachersaround the U.S., the faculty remain (29)_ that their work as educators can be measured by a“learning (30)_ ” such as a graduates ability to investigate and reason. However, the professorsneed not worry so much. The results of a recent experiment showed that professors can use (31)_ met

20、rics to measure how well students do in three key areas: critical thinking, written communication, and quantitative literacy. Despite the success of the experiment, the actual results are worrisome, and mostly (32)_ earlier studies. The organizers of the experiment concluded that far fewer students

21、were achieving at high levels on critical thinking than they were doing for written communication or quantitative literacy. And that conclusion is based only on students nearing graduation. American universities, despite their global (33)_ for excellence in teaching, have only begunto demonstrate wh

If the intellectual worthof a college degree can be (35)_ measured, more people will seek higher educationand comeout better thinkers. 注意：此

25、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 an

26、d other greenhouse gases. BPolicymakers 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 cli

27、mate change. That approach also offers fiscal benefits. COil 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 pr

28、oduction capacity, eventually shifting the oil supply curve backward and bringing prices back up as existing oil fields 一which can be tapped at relatively low marginal costare depleted. In fact, in line with past experience capital expenditure in the oil sector has dropped sharply in many producing

29、countries, including the United States. The dynamic adjustment to low oil prices may, however, be different this time around. DOil 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 glo

30、bal over-supply. In addition, other factors are putting downward pressure on oil prices: change in the strategies 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-

31、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, sup

32、port this view. ENatural gas and coalalsofossil fuelshave 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 Am

33、erican 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

34、. Coal prices also are low, owing to over-supply and the scaling-down of demand, especially from China, which bums half of the worlds coal. FTechnological innovations have unleashed the power of renewables such as wind, hydro, solar, and geothermal (地热).Even Africa and the Middle East，home to econom

35、ies 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. GProgress in the development of renewables could

36、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 fuels30% each for coal and oil, 25% for natural gas. But renewable energy will have to displace fossil fuels to a much gr

37、eater extent in the future to avoid unacceptable climate risks. HUnfortunately, 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 a

38、re strongly encouraged by higher fossil fuel prices. The same is true for new technologies for alleviating fossil fuel emissions. IThe current low fossil fuel price environment will thus certainly delay the energy transition from fossil fuel to clean energy sources. Unless renewables become cheap en

39、ough that substantial carbon deposits are left underground for a very long time, if not forever, the planet will like be exposed to potentially catastrophic climate risks. JSome climate impacts may already be discernible. For example, the United Nations Children Fund estimates that some 11 million c

40、hildren in Africa face hunger, disease, and water shortage 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. KNations from around the world h

41、ave gathered in Paris for the United Nations Climate Change Conference, COP 21, with the goal of a universal and potentially legally-binding agreement reducing greenhouse gas emissions. We need very broad participation to fully address global tragedy that results when countries fail to take into acc

42、ount the negative impact of their carbon emissions on the rest of the world. Moreover, non-participation by nations, if sufficiently widespread, can undermine the political will of participating countries to act. LThe nations participating at COP 21 are focusing on quantitative emissions-reduction c

43、ommitments. Economic reasoning shows that the least expensive way for each country is to put a price on carbon emissions. The reason is that when carbon is priced, those emissions reductions that are least costly to implement will happen first. The International Monetary Fund calculates that countri

44、es can generate substantial fiscal revenues by eliminating fossil fuel subsidies and levying carbon charges that capture the domestic damage caused by emissions. A tax on upstream carbon sources is one easy way to put a price on carbon emissions, although some countries may wish to use other methods

45、, such as emissions trading schemes. In order to maximize global welfare, every countrys carbon pricing should reflect not only the purely domestic damage from emissions, but also the damage to foreign countries. MSetting the right carbon price will therefore efficiently align the costs paid by carb

46、on users with the true social opportunity cost of using carbon. By raising relative demand for clean energy sources，a carbon price would also help align the market return to clean-energy innovation with its social return, spurring the refinement of existing technologies and the development of new on

47、es. And it would raise the demand for technologies such as carbon capture and storage, spurring their further development. If not corrected by the appropriate carbon price, low fossil fuel prices are not accurately signaling to markets the true social profitability of clean energy. While alternative

48、 estimates of the damage from carbon emissions differ, and its especially hard to reckon the likely costs of possible catastrophic climate events, most estimates suggest substantial negative effects. NDirect subsidies to research and development have been adopted by some governments but are a poor s

49、ubstitute for a carbon price; they do only part of the job, leaving in place market incentives to overuse fossil fuels and thereby add to the stock of atmospheric greenhouse gases without regard to the collateral (附带的）costs. OThe hope is that the success of COP 21 opens the door to future international agreement on carbon prices. Agreement on an international carbon-price floor would be a good starting p
