听力原文: We can agree with primitive man that fond is a basic neeD.but we differ from him in our food wants because of the wide variety of food we have available compared with him; we have a wider choicE.Take fruit for example, not only can we enjoy the fruits grown in his century, but because of modern methods of transport and food preservation, we can also enjoy more fruits from foreign countries, whereas primitive man is limited in his choice to the kinds of fruit which actually grow where he lives.
However they differ in satisfying their hunger, primitive and civilized men both experience the basic need for fooD.
The same is true of the second of our human needs. Clothing is necessary m regulate the heat of our bodies. Since we live in a temperate climate we need more clothes than people living in tropical conditions. LikewisE.our clothing needs to change with the seasons.
Shelter, the third of our needs, depends upon the climate, the skill of the builder, one's social position, and the materials, availablE.The simple shelter of primitive man would not do for us, and yet it satisfies his needs. The three- bedroom suburban house of the average family would not be grand enough for a rich family, and yet the modem house contains many of the material comforts which were denied to the Kings and Queens of olD.

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 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 color-coded map showing where plants were running 'fevers'. Farmers could then spot-spray, using 50% to 70% 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 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% 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 pesticidesB.facing an infrared scannerC.in poor physical conditionD.exposed to excessive sun rays
