8、 morning. Section B Directions: In this section, you will hear two passages. At the end of each passage, you will hear three or four questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A), B),

9、 C) and D). Then mark the corresponding letter on Answer Sheet 1 with a single line through the centre. Questions 9 to 12 are based on the passage you have just heard. nationwide study of college graduates had shown that more than a third had made no _26_ gains in such mental abilities during their

10、school years. Mr. Daniels needed to _27_ the high cost of attending Purdue to its students and their families. After all, the percentage of 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 s

11、kills. Yet like many college teachers around 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 professors need not worry so much. The results of a recent experiment showed that profe

12、ssors can use _31_ metrics 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 tha

13、t far fewer students 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 be

14、gun to demonstrate what they can produce in real-world learning. Knowledge-based degrees are still important, but employers are _34_ advanced thinking skills from college graduates. If the intellectual worth of a college degree can be _35_ measured, more people will seek higher education-and come ou

15、t better thinkers. A) accurately B) confirm C) demanding D) doubtful E) drastically F) justify G) monopolized H) outcome I) predominance J) presuming K) reputation L) significant M) signify N) simultaneously O) standardized Section B Directions: In this section, you are going to read a passage with

16、ten statements attached to it. 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

17、 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 technolo

18、gies. 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

19、 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 t

20、his 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 ex

21、penditure 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 mil

22、lion 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-do

23、wn 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 onl

24、y a modest recovery of prices to around $60 a barrel by 2019, support this view. E Natural gas and coalalso fossil 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,

25、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 signif

26、icant 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 worlds coal. F Technological innovations have unleashed the power of renewables such as wind, hydro, sola

27、r, 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 renewa

28、ble 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 fuels30% each for coal and oil, 25% for natural ga

29、s. 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 s

30、trong 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 fr

31、om 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. Fo

32、r example, the United Nations Childrens 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. K Nations from around the world have gathered in Paris for the United Nations Climate Change Conference, COP 21, with the goal of a universal and potentially legally-binding agreem
