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(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 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.Plants will send out an increased amount of heat when they are________.

Cancer is among the top killer diseases in our society today and scientists have found out that stress(紧张) helps to bring it on. It is worthwhile to consider, therefore, what are the causes of stress in our life, and whether we can do anything about them.
Are we underemployed, or overburdened with too many responsibilities? Do we have a right balance of work and leisure(闲暇) in our lives? Are our relationships with family, friends or fellow workers all they should be?
All these things can be a cause of stress, and it is best to face them honestly, and bring our frustrations(沮丧,挫败) into the open. People who have a good row and then forget it are doing their health better than shoes who bottle up their feelings.
If our self-examination has brought any causes of stress to light, let us consider what we can do about them. It is possible to change jobs. We can make more leisure and fill it more happily, if we will accept a different living standard. We can improve our personal relationships by a different attitude. It is we who allow other people to make ourselves unhappy. Often the little things that disturb us are not worth an hour’s anger. The teaching in the Bible “Don’t let the sun go down upon your wrath(愤怒)” is good advice from the health point of view as well as the religions(宗教,信仰).

I had just gone to bed after a very hard day when the phone rang. It was a strange farmer. I had never met him before although I had often heard people talk about him.

I really didn’t know who she was but I had to go.
It had been snowing heavily that day and I didn’t know the way. I had been driving for at least an hour when I finally found his place. He was standing there, waiting for me. It seemed that Milly had died. “She meant more to me than anyone even my own wife!” he said. I could see that he had been crying. I thought something terrible had taken place, a possible scandal(丑闻). I was even more surprised when he told me he had put her in the barn(厩). “I couldn’t leave her in the cold!” he said. Milly had clearly been a secret lover of his. I was about to tell him he could not expect me to cover anything up when he opened the barn door. He lifted his candle and I saw a dark figure on the ground.

At one time or another most farmers have problems with mice. This is especially true for grain farmers. Mice eat a lot of grain. They also carry diseases(疾病), which people can get from eating or touching grain the mice have made dirty. Farmers can use special grain storage building or they can kill the mice. However, both methods can be costly. Farmers must buy materials to build the special grain storage buildings or chemical poisons to kill the mice.
Here is a way to kill mice without spending a lot of money. It is a simple but effective king of mouse trap. The method is first used by some farmers in the west African country of Mali. An agricultural expert in Mali reported about the Mali mouse trap in a magazine. The expert reported that his gardener caught 150 mice in just one night. The gardener used four traps. The trap is easy to make. First, remove the top from a 20 liter metal or plastic container(容器). Put it n a hole in the ground. The top edge of the container should be the level with the surface of the ground. Fill the container with water to within eight centimeters of the top. Add tiny pieces of grain wastes. They should float on the water. Also put some wastes on the ground near the trap. During the night, mice will come out to eat the grain wastes. They will fall into the container and drown. Replace the food in the trap every night.
56. According to the passage, used the mouse trap first.
A. an agricultural expert in the west Africa B. farmers in the United States
C. an American gardener D. farmers in Mali
57. What does the passage mainly tell us?
A. A simple and effective method used by farmers to kill mice.
