     Critics say Microsoft Windows 95 must be able to do what the company has said or sales will fall sharply.

This could mean the public would reject future Microsoft products. The public would lose trust in the company. Some people say this will not happen. They say Microsoft sent out several thousand copies of their new product to computer experts to test several months before it was released. Problems that these testers found were

immediately corrected. Microsoft representatives are working to solve all the other problems buyers find when

they try the new system. Computer industry experts say that if there are no major problems Microsoft can

expect to earn about 7 thousand million dollars from Windows 95 in the first two years. The experts say this

could be just a beginning for Microsoft and the whole computer industry. The experts say Windows 95 can

help the user do many different and difficult tasks. They say this means the sale of more powerful computers

and other computer products will increase as people learn about the new Microsoft product. Other companies

say Windows 95 is not a big improvement. The Apple Computer Company says its Mackintosh Operating System has been able to do many of the same things since 1989. For example, it has been able to let users work two

different programs at the same time. The Amega Computer also has offered this for almost ten years. And IBM

says the operating system it developed about 7 years ago is very similar.

1. In the passage the writer _____.

A. thinks Windows 95 will be a success

B. is doubtful about what Microsoft Company has promised

C. shows no opinion of his own

D. is advertising Windows 95 for Microsoft Company

2. Some believe that Windows 95 will not only bring in a lot of money but also _____.

A. replace the older products

B. threat (威胁) other computer companies

C. help sell other products produced by Microsoft Company

D. bring about changes in other fields

3. All the following show Windows 95 is important to Microsoft Company except _____.

A. Windows 95 will build up people's faith (信心) in the country's future products

B. Windows 95 will bring about a great change in the whole computer industry

C. other companies don't think highly of Windows 95

D. Windows 95 will help sell more powerful computers

     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.

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

A. facing an infrared scanner

B. sprayed with pesticides

C. in poor physical condition

D. exposed to excessive sun rays

2. In order to apply pesticide spraying precisely, we can use infrared scanning to________.

A. estimate the damage to the crops

B. draw a colourcoded map

C. measure the size of the affected area

D. locate the problem area

3. Farmers can save a considerable amount of pesticide by________.

A. resorting to spotspraying

B. transforming poisoned rain

C. consulting infrared scanning experts

D. detecting crop problems at an early stage

4. The application of infrared scanning technology to agriculture met with some difficulties-________.

A. its high cost

B. the lack of official support

C. the lack of financial support

D. its failure to help increase production

5. Infrared scanning technology may be brought back into operation because of________.

A. full support from agricultural experts

B. growing concern about the excessive use of pesticides on crops

C. the forceful promotion by the Department of Agriculture

D. the desire of farmers to improve the quality of their produce
