1、山东新高考高二英语时文阅读精练含答案解析山东新高考高二英语时文阅读精练（含答案解析）AWhen Anna left her car outside Oxford on January 10th, she had little reason to think that criminals would take an interest in the 12-year-old car. Yet the next afternoon a group of thieves were spotted sawing off its catalytic converter(转换器). Such incident

2、s have become more frequent across Britain as prices for palladium and rhodium(铑), metals contained in the devices, have rocketed. The price of rhodium has risen by 63% in the first three weeks of January alone, to $9,850 per ounce, around six times that of gold.Demand from carmakers is surging. Mor

3、e than four-fifths of global demand for rhodium comes from the automotive industry. The metal, together with platinum and palladium, helps turn toxic gases in a vehicles exhaust system into less harmful substances before they leave the tailpipe. Facing stricter emissions regulations around the world

4、, carmakers are taking even more of a shine to these metals. Although the price of palladium has reached a record high, that of platinum has stayed relatively stable. The contrast reflects a shift in production towards petrol and hybrid cars, which tend to use greater quantities of palladium in thei

5、r converters.Rhodium is used in both petrol and diesel cars. That is because it is especially good at cleaning up nitrogen oxides(氮氧化物), says Roger Breuer, an analyst at an investment firm. Another reason why its price is sky-high is the tightness of its supply. More than four out of every five ounc

6、es of rhodium are mined in South Africa. According to an analysis by Stantec, a consulting firm, a mine in the Waterberg region of South Africa due to begin development this year will produce 63% palladium, 29% platinum, 6.5% gold and just 1.5% rhodium.Rhodium is expected to remain in high demand th

7、is year. BASF, a German chemicals giant, reckons that Chinese carmakers demand for the metal will increase by 40% in 2020. But because electric vehicles do not use catalytic converters, demand in the longer term is far from assured. Rhodium could quickly lose its sheen.1. Why did the thief have an i

8、nterest in Annas old car?A. Because her car looked good. B. Because her car was parked outside a college. C. Because the price of rhodium surged. D. Because the demand of converter increased.2. Why do carmakers need metals like rhodium, platinum and palladium?A. Because these metals make the car val

9、uable.B. Because these metals are convenient to get.C. Because the price of these metals is relatively low.D. Because these metals help clean car emission.3. What can we learn from Paragraph 3?A. Neither petrol cars nor diesel cars need rhodium.B. The price of rhodium is believed to be low.C. Rhodiu

10、m is mostly produced in South Africa.D. Sufficient supply leads to the high price of rhodium. 4. According to the passage, what do you think of the future price of rhodium?A. The price of rhodium will continue rising.B. The price of rhodium may decline.C. The price of rhodium will not change.D. Ther

11、e isnt a clear clue in the passage.BScientists Use Tiny Spring Magnets to Harmlessly Dissolve MicroplasticsA University of Adelaide-led research team has developed a new approach to cleaning water sources of the microplastics that pollute them without harming nearby microorganisms. The researchers h

12、ave developed a technique to break down the microplastics using tiny coil-shaped carbon-based magnets. Although often invisible to the naked eye, microplastics are very common pollutants. Microplastics adsorb organic and metal contaminants as they travel through water and release these hazardous sub

13、stances into organisms living near water when eaten, causing them to accumulate all the way up the food chain.To separate the microplastics, the researchers had to generate short-lived chemicals called reactive oxygen species, which trigger chain reactions that chop the various long molecules that m

14、ake up microplastics into tiny and harmless parts that dissolve in water. However, reactive oxygen species are often produced using heavy metals such as iron, which are dangerous pollutants in their own right and thus unsuitable in an environmental context.To get around this challenge, the researche

15、rs found a greener solution in the form of carbon nanotubes laced with nitrogen（氮）to help boost generation of reactive oxygen species. Shaped like springs, the carbon nanotube catalystsremoved a significant part of microplastics from water samples in their lab over the course of just eight hours.“It

16、 turns out that the degradationproducts of microplastic are completely harmless, and they can also be used as a carbon source for algae growth,” says project co-leader Dr. Xiaoguang Duan. “The microplastics are completely transformed into carbon dioxide or other harmless substances, and they will no

17、t cause any unpleasant or poisonous effects to microorganisms or fish or other animals in water.”Furthermore, the springs were able to remain stable themselves in the harsh oxidativeconditions needed for microplastics breakdown because the loop shape increases stability and maximizes reactive surfac

18、e area. As a bonus, the minute springs became magnetic after the team included a small amount of manganese（锰）buried far from the surface of the nanotubes to prevent it from leaching into water.As no two microplastics are chemically quite the same, the researchers next steps will center on ensuring t

19、hat the nanosprings work on microplastics of different compositions, shapes and origins. They also intend to continue to absolutely confirm the non-poison of any chemical compounds occurring as in between or by-products during microplastics breaking down. “If plastic contaminants can be repurposed a

21、ke or find out there the things required to support lifeincluding food, water and breathable air. Researchers are already working on ways to grow food in space, and icy deposits that could provide water are known to exist on some stars. Besides being available for drinking, such water could be split

22、 into its constituent elements of hydrogen and oxygen using electricity from solar panels. Such electrolysis(电解) is already the main way of making oxygen on the International Space Station. Now, though, a group of European researchers have discovered how to take water out of the loop. They have work

23、ed out how to generate oxygen by electrolysing regolith(风化层), the dusty material that covers the Moons surface.The European Space Agency announced on January 17th that a prototype oxygen-generating plant using regolith has been set up at its research center in the Netherlands. Not only could such a

24、machine use a readily available material to make breathable air for people living on the Moon, it could also be used to produce rocket fuel, says Beth Lomax, who is working on the project. Liquid oxygen is one of the main propellants employed in space rockets. A lunar refuelling station would be goo

25、d for deep-space exploration because the Moons low gravity means less fuel is required for take-off. Oxygen, in the form of oxides, is the most abundant element in lunar regolith, accounting for 40-45% of its mass. That the element can be extracted(提取) from regolith was demonstrated successfully las

Metalysis has developed a form of electrolysis that can extract high-value metals such as tantalum from powdered metal oxides mixed into a bath of molten salt. Although the process operates at around 900C, it do
