| Even plants can run a fever, especially
when they’re under attack by insects or disease. But unlike humans, plants can
have their temperature taken from 3,000 feet away-- straight up. A decade ago,
adapting the infrared 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.

Questions 61 to 65 are based on the following passage:
Shortly after the war, my brother and I were invited to spend a few days’ holiday with an uncle who had just returned from abroad. He rented a cottage in the country, although he rarely spent much time there. The cottage, however, had no comfortable furniture in it, many of the windows were broken and the roof leaked, making the whole house damp.

I was so tired after the long train journey that I would have preferred to go to bed, but I could not bear to miss any of my uncle’s exciting tales.
He was just in the middle of describing a rather terrifying experience he had, when there was a loud crash from the bedroom above, the one where my brother and I were going to sleep.
