Directions: Read the following text. Answer the questions on each text by choosing[A], [B], [C]or[D]. 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(红外线)scanning technology developed for military purposes and other satelities, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones were 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. 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 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 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 that 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. In order to apply pesticide spraying precisely, we can use infrared scanning to ______ .

Directions: Read the text from a magazine article in which several people expressed their different opinions on the same issue. Please match the name of each person to one of the statements given below. Douglas Spensor I want the maximum amount of compensation from the new supermarket owners for both loss of business and inconvenience of moving. As the most recent of the tenants in these shops, I would like to say I feel it is very unfair to calculate compensation based on length of time in residence. I think it should be on the amount of goods Sold day by day in shop. I get more than the tobacco and magazine vendor although they have dealt in this supermarket for over fifteen years. My goods are more expensive. Besides, my business is excellent and I have just employed five assistants. Sony Herry I want the maximum amount of compensation to be paid to all shop owners. The formula for the compensation can be worked out in detail later, but I want a deal that will give me the most amount of money as my business, not very big, is sufficient to support my wife and 12 year old son. And I have planned to retire soon anyway for I have worked here for more than 15 years. I hope we will make an agreement among all the shop owners not to accept employment in the new supermarket unless they pay us enough compensation. I insist that all my colleagues stick to this agreement. Maltese Brown I feel I have the greatest amount of money to lose than any of the other shop owners as I have recently spent a large amount of money on new valuable stock which I need to sell. I don’ t want any compensation at all. I simply want the landlord to be honorable and to allow us to renew our tenancy agreements. I have made an agreement with the other shop owners not to accept employment in the new supermarket if it is offered, unless all the shop owners can work there. Tom Clouse Something should be done about this situation. The reputation of the business is most important. Many people come to my salon regularly only because I am the best hairdresser here. My business has been very successful over the last five years. But if I close up my shop during the decoration, I will lose many of my customers. When considering the compensation, we should take into account of the factor of reputation. Durante Li I do not want the market to close. The majority of my customers live near the market and it would be very difficult for them to travel to the other side of this district for meat. And the store of my goods is very expensive. I need fridges, even icehouses. The compensation should cover all the costs, otherwise, I wouldn’ t move out. Now match each of the persons with the appropriate statement. Note: there are two extra statements. Statements Sony Herry
