Not long age, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly by night？ Tests with artificial stars have proved that certain night - flying birds are able to follow the stars in their long - distance flights.
A dove (鸽子) had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird's cage was placed under an artificial star - filled sky. (76) The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the position of the artificial stars caused a change in the direction of his flight.
(77) But the stars are apparently their principal means of navigation (航行) only. When the stars are hidden by clouds, they seemingly find their way by such landmarks as mountain ranges, coast lines, and river courses. But when it's too dark to see these, the doves circle helplessly, unable to find their way.

B．have only recently been discovered
C．are known by us

The summer holidays are the best part of the year for most children.The weather is usually good, so that one can spend most of one’s time playing in the garden or, if one lives in the country, out in the woods and fields.Even if one lives in a big town, one can usually go to a park to play.
The best place for a summer holiday, however, is the seaside.Some children are lucky enough to live near the sea, but for the others who do not, a week or two at one of the big seaside towns is something which they will talk about for the whole of the following year.
In England, it is not only the rich who can take their children to the seaside; if a factory worker or a bus driver, a street cleaner or a waiter wants to take his wife and children to Southend or Margate, Blackpool or Clacton, he is usually quite able to do so.
Now, what is it that children like so much about the seaside？ I think it is the sand, sea and sun more than any other things.Of course, there are lots of new things to see, nice things to eat, and exciting things to do, but it is the feeling of sand under one’s feet, of salt water on one’s skin, and of the warm sun on one’s back that makes the seaside what it is.

Even better, Paley's Remote Scanning Services Company could detect crop problems before they be- came 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, code map showing where plants were running "fevers". Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.
The had 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.
Plants will emit an increased amount of heat when they are ______. ()
A．sprayed with pesticides
B．in pour physical condition
C．facing an infrared scanner
D．exposed to excessive sun rays
They discussed what Mother and I should do during the day, what Santa Claus should give a fellow for Christmas, and what steps should be taken to brighten the home. There was that little matter of the baby, for instance. Mother and I could never agree about that. Ours was the only house in the neighborhood without a new baby, and Mother said we couldn't afford one till Father came back from the war because it cost seventeen and six. That showed how foolish she was. The Geneys up the road had a baby, and everyone knew they couldn't afford seventeen and six. It was probably a cheap baby, and Mother wanted something really good, but I felt she was too hard to please. The Geneys' baby would have done us fine. Having settled my plans for 'the day, I got up, put a chair under my window, and lifted the frame. high enough to stick out my head. The window overlooked the front gardens of the homes behind ours, and beyond these it looked over a deep valley to the tall, red-brick house up the opposite hillside, which were all still shadow, while those on our side of the valley were all lit up, though with long storage shadows that made them seem unfamiliar, stiff and painted.
