     Even plants 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(紅外線)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(殺蟲劑)spraying rather than rain poison on a whole field, which invariably includes plants that don't have pest 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 colourcoded map showing where plants were running "fevers". Farmers could then spotspray, 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 longterm 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 send out an increased amount of heat when they are________.
A. facing an infrared scanner
B. sprayed with pesticides
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. draw a colourcoded map
C. measure the size of the affected area
D. locate the problem area
3. Farmers can save a considerable amount of pesticide by________.
A. resorting to spotspraying
B. transforming poisoned rain
C. consulting infrared scanning experts
D. detecting crop problems at an early stage
4. The application of infrared scanning technology to agriculture met with some difficulties-________.
A. its high cost
B. the lack of official support
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________.

閱讀理解
    Even facts "forgotten" by people during a busy day may be retrieved if this is followed by a good
night's sleep.
    Researchers from the University of Chicago asked volunteers to remember simple words . Many
found their memories letting them down towards the end of the day, but the following morning, those
who had slept well could recall much more.
    Researchers, writing in the journal Nature, said the brain could "rescue" lost memories during the
night.
    When the brain is first asked to remember something that memory is laid down in an "unstable" state,
meaning that it is possible that it could be lost . At some point, the brain consolidates those it deems
important into a "stable", more permanent state . However, the Chicago researchers suggested that it
was possible for a "stable" memory to be made "unstable" again . This would mean that memories
could be modified then filed away again in the face of new experiences.
    The 12 volunteers tested in the experiment were played words created through a speech synthesizer
which were purposely difficult to understand . Initially, the written version of the word  from the audio
version only . Tests revealed that the ability to recall the right word tended to tail off as the day ended.
    However, when the volunteers were retested after a good night's sleep, they were able to recall
some words that they had " forgotten" the previous evening.
    Dr Daniel, one of the study authors, said: "Sleep consolidates memories, protecting them against
subsequent interference or decay . Sleep also appears to "recover" or restore memories." He said: "If
performance is reduced by decay, sleep might actively recover what has been lost."
   Dr Karim Nader, from the Department of Psychology in McGill University in Montreal, said:
"Memory research is undergoing a transformation-no longer is memory thought to be a hard-writing
of the brain, instead it seems to be a process of storage and restorage."
    Sleep helps some memories "mature" and also prunes out unimportant memories.

1. What does the first paragraph implies?
A . A busy day makes people forget things easily.
B . People need a good night's sleep after a busy day.
C . A good night's sleep helps memories.
D . A good night's sleep helps people forget a busy day.

2 . The words the 12 volunteers played in the experiment were not ____
A . created through a speech synthesizer
B . hard to understand
C . available at the beginning
D . designed to test people's ability of understanding

3 . According to the passage, memory_____
A . is a hard-writing of the brain
B . is not a process of storage
C . is not a process of restorage
D . will be mature with the help of sleep

4 . Which of the following is NOT true?
A . When people first remember something, the memory is in an "unstable state".
B . The brain will change those important unstable memories into stable.
C . Once the memory become stable, it will never become unstable again.
D . Sleep can protect memories from being harmed.
