　　Even plant can run a fever, especially when they’re under attack by insects or disease. But unliman, plants can have their temperature taken from 3, 000 feet away straight up. A decade ago, adopting the infrared （红外线）scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide （杀虫剂）spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest （害虫）problems.
　　Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3, 000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running “fevers”. Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.
　　The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long - term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States, ”says George Oerther of Texas A & M. Ray Jackson , who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago.
　　1. Plants will emit an increased amount of heat when they are _____________.
　　A. sprayed with pesticides　　B. facing an infrared scanner
　　C. in poor physical condition　　D. exposed to excessive sun rays
　　2. In order to apply pesticide spraying precisely, we can use infrared scanning    to____________.
　　A. estimate the damage to the crops　　
　　B. measure the size of the affected area
　　C. draw a color-coded map　　
　　D. locate the problem area
　　3. Farmers can save a considerable amount of pesticide by______________.
　　A. resorting to spot-spraying　　
　　B. consulting infrared scanning experts
　　C. transforming poisoned rain　　
　　D. detecting crop problems at an early stage
　　4. The application of infrared scanning technology to agriculture met with some   difficulties _______________.
　　A. the lack of official support　　
　　B. its high cost
　　C. the lack of financial support　
　　D. its failure to help increase production
　　5. Infrared scanning technology may be brought back into operation because of_____________.
　　A. the desire of farmers to improve the quality of their produce
　　B. growing concern about the excessive use of pesticides on crops
　　C. the forceful promotion by the Department of Agriculture
　　D. full support from agricultural experts

　　When 12 girls from San Fernando High School in California received a grant (经费) to develop an invention to solve a real-world problem, they decided to create a solar-powered shelter to help the homeless.
　　For over a year, the girls have been using all their free time to complete the  ___1___“They have this amazing internal (内心的)  2  that I’ve never seen in any individual,”Violet Mardirosian, a teacher at San Fernando High who is  3  with the team on the project, told The Huffington Post. “I thought  4___ that maybe some of them would give up, say ‘I didn’t  5 _ this much wort they haven’t. They’re just working hard and they’re not giving up and they’re super  6 __ .”
　　Living in a low-income community, the girls have seen the  7  of homelessness first-hand. Many of them are from immigrant families and hoped the  8  , which is powered by rechargeable solar panels (控制板), would help the  9  .
　　Seventeen-year-old Maggie Mejia told the Huffington Post that  10  she had no previous  11  experience, the girls figured out as a team how to  12  the shelter using how-to videos and books that taught them how to code. But the most important  13  she’s learned during the project isn’t technical.
　　“I’ve learned a lot about  14  others, helping the community and being selfless and showing a better world to other people and  15  someone else’s life,”she said. The project was carried out with DIY Girls, a nonprofit that helps fund STEM –science, technology, engineering and math –projects for  16  .
　　Mardirosian said all the participating students have  17  their interest in STEM through this project.
