But research now suggests global warming could make it much worse. To get off the ground in really hot weather, planes may be forced to carry fewer passengers. That might mean a little more space, which would be good. However, it also would make the passengers pay more.Average air temperatures around the world are rising because people are polluting the air with an increasing number of greenhouse gases, which, such as carbon dioxide, are a byproduct (副产品) of burning fuels. Those warmer temperatures can influence an airplanes ability to fly because air molecules (分子) spread out more as the air warms. This produces less lift under a planes wings, so a plane must be lighter to take off in hot weather than on cooler days.It can even prove too dangerous for some planes to attempt a takeoff. A record of June heat wave in the American Southwest, for instance, caused flight cancellations in Phoenix, Ariz. One airlines planes were cleared to operate only up to 47.8 degree Celsius. On June 20, Phoenix reached 48.3 ！Radley Horton is a climate scientist at Columbia University. Two years ago, he and his graduate student Ethan David Coffel studied the impact of warming at four US airports and found that warming of track could triple (使成三倍) the number of days when planes face weight restrictions. Later, they explored the impact of rising temperatures on live types of commercial planes flying out of 19 of the worlds busiest airports. In the coming decades, as many as one to three out of every 10 flights that take off during the hottest time of day could face weight. That would be equal to taking a dozen people off the plane, the researchers calculated.1How would global warming affect air travel according to the first paragraph?AItll add to the danger of flying.BItll increase passengers travel cost.CItll make flying much more comfortable.DItll encourage more people to travel by plane.答案：B细节理解题。根据第一段最后一句 “However, it also would make the passengers pay more.” 可知，这会使乘客支付更多，故选B。2What is the second paragraph actually intended to explain?AHow global warming is happening.BWhat decides a planes ability to fly.CWhy global warming affects flying.DWhere greenhouse gases are created.答案：C推理判断题。根据本段中的“Those warmer temperatures . lift under a planes wings”可推测出，本段主要介绍了空气变暖怎样影响了飞机的升空，故选C。3What is the last paragraph mainly about?AReasons for flight cancellation.BThe findings of a weightrelated research.CThe tendency of temperature change.DEffects of hot air on financial growth.答案：B段落大意题。最后一段主要讲述科学家针对世界上最繁忙的一些飞机场进行研究，研究表明，在最热的天气里，飞机的重量受到了影响，故选B。4What should be the best title for the text?AAir Travel Isnt Recommended during Hot WeatherBRising Temperatures May Reduce the Number of FlightsCWeight Restrictions Are More Common in More AirportsDHotter Air May Lead to Planes Carrying Fewer Passengers答案：D标题判断题。本篇文章主要介绍了飞机受气温的影响，温度过高时会使它承载的重量减少，即装载的乘客会减少，故选D。B(2018全国卷)We may think were a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices (装置) well after they go out of style. Thats bad news for the environmentand our walletsas these outdated devices consume much more energy than the newer ones that do the same things.To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its lifefrom when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation. Desktop computers, basic mobile phones, and boxset TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and ereaders showed up in 2007.As we accumulated more devices, however, we didnt throw out our old ones. “The livingroom television is replaced and gets planted in the kids room, and suddenly one day, you have a TV in every room of the house，” said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. Were not just keeping these old deviceswe continue to use them. According to the analysis of Babbitts team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions (排放) more than doubling during the 1992 to 2007 window.So whats the solution (解决方案)? The teams data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more ondemand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%. 5What does the author think of new devices?AThey are environmentfriendly.
