Even plant can run a fever, especially when they’re under attack by insects or disease. But unlike human, 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 sent out 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 that 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（改进）ininfrared 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, 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.

Learning style theory suggests that different people have different ways of obtaining information and use various methods to demonstrate（证明）their intelligence and ability. Although experts have many ideas and categories of learning, it is evident that people learn in three basic styles.
When learning something new, if you prefer to read the information, you are probably a student who learns through seeing. These learners like to see teacher’s facial expressions and body language clearly and rend to sit at the front of the classroom. They take detailed notes, think in pictures and can most easily absorb information from textbooks with diagrams, graphs, photographs and drawings.
Students who find it easiest to learn a new concept by hearing a teacher explain it are learning through listening. Reading aloud, using a tape recorder, hearing anecdotes（趣闻）and talking things through are the best methods for these learners to acquire new information. They give close attention to both the content of the discussion and the way that things are said, such as how the sound of the voice and speed of speech show the mood of the speaker.
Learning through doing means being active in exploring the environment and finding out about things by moving and touching. Students who have this learning style take a hands-on approach to education and enjoy experiments or surveys. They do not like to sit still for long periods of time and sometimes find it hard to concentrate when reading or listening.
Teachers study people’s various ways of learning as part of their training. They select a variety of activities to suit their students’ different learning styles. However, restrictions of time, space and resources often make it impossible for teachers to provide the best exercises for all learners. If you are aware of you own learning style, there is a lot you can do personally to improve your study skills and find the most appropriate ways to approach your study tasks. As a result, you will be able to manage your own learning and study more effectively.
