3、 for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the air. It flies using a 23-gallon tank of gas and burns 5 gallons per hour in the air. On the ground, it gets 35 miles per gallon.Around 100 people have already put down a $10,000 deposit to get a Transition w
4、hen they go on sale, and those numbers will likely rise after Terrafugia introduces the Transition to the public later this week at the New York Auto Show. But dont expect it to show up in too many driveways. Its expected to cost $279,000.And it wont help if youre stuck in traffic. The car needs a r
5、unway. Inventors have been trying to make flying cars since the 1930s, according to Robert Mann, an airline industry expert. But Mann thinks Terrafugia has come closer than anyone to making the flying car a reality. The government has already permitted the company to use special materials to make it
6、 easier for the vehicle to fly. The Transition is now going through crash tests to make sure it meets federal safety standards.Mann said Terrafugia was helped by the Federal Aviation Administrations decision five years ago to create a separate set of standards for light sport aircraft, which are low

Its expected to cost $279,000”可知，因为Transition 的价格较高，所以不太可能在太多的马路上出现。故选C。31.D 【解析】标题归纳题。浏览全文，主要从飞车的试飞成功、飞车的构架以及多年以前人们对飞车的设想至今成为现实展开说明。故选D。Passage 1（2018年新课标卷I）体裁话题词数难度建议时间说明文 新旧电子设
11、备的差别 3637分钟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 Thats bad news for the environment and our wallets as these outdated devices consu
12、me 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 life from when its minerals are
13、 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 box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players,
14、smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.As we accumulated more devices, however, we didnt throw out our old ones. “The living-room television is replaced and gets planted in the kids room, and suddenly one day, you have a TV in every room of th
15、e 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 devices we continue to use them. According to the analysis of Babbitts team, old desktop monitors and box TVs with cathode ray tubes are the wor
16、st 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
17、new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.32. What does the author think of new devices?A. They are e
18、nvironment-friendly.B. They are no better than the old.C. They cost more to use at home.D. They go out of style quickly. 33. Why did Babbitts team conduct the research?A. To reduce the cost of minerals. B. To test the life cycle of a product.C. To update consumers on new technology.D. To find out el
19、ectricity consumption of the devices.34. Which of the following uses the least energy?A. The box-set TV. B. The tablet. C. The LCD TV. D. The desktop computer.35. What does the text suggest people do about old electronic devices?A. Stop using them. B. Take them apart. C. Upgrade them. D. Recycle the
20、m. 【文章大意】本文是一篇科普说明文。文章讲述了新旧电子设备的差别，旧电子设备耗能高、不环保。所以作者主张使用新电子设备。33.D 【解析】细节理解题。 根据文章第二段中的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 life 可知，
21、Babbitts team研究的目的是弄清楚这些设备用了多少电。故选D。34.B 【解析】细节理解题。根据文章最后一段中的They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.可知，平板电脑是耗能最少的电子设备，可以降低44%的耗能。 故选B。35.A 【解析】推理判断题。根据文章的整体内容可知，因为旧的电子设备耗能高，不环保。所以作者建议停止使用旧的电子设备。故选A。Pass

In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.Sustainability(可持续性)The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 5
25、0 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids (水解胶体) from plentiful renewables like algae(藻类) and grass to replace the familiar ingredients(烹饪原料). 3D prin
26、ting can reduce fuel use and emissions. Grocery stores of the future might stock food that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.NutritionFuture 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia Univers
27、ity, said, “Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterdays bread from the supermarket, youd eat something baked just for you on demand.”ChallengesDespite recent advancements in 3D food printing, the ind
28、ustry has many challenges to overcome. Currently, most ingredients must be changed to a paste(糊状物) before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are
29、restricted to dry ingredients, because meat and milk products may easily go bad. Some experts are skeptical about 3D food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants.46.
