As a computer exhibition Bill gates reportedly compared the computer industry with the auto industry and stated: “If GM had kept up with technology like computer industry has, we would all be driving twenty-five dollar cars that got 1000 miles to the gallon.”

In response to Bill’s comments, General Motors announced a news release stating: if GM had developed technology like Microsoft, we would be driving cars with the following characteristics:

1. For no reason your car would crash twice a day.

2. Every time they repaired the lines on the road you would have to buy a new car.

3. Sometimes your car would die on the free way for no reason and you would just accept this, restart and drive on.

4. Only one person at a time could use the car, unless you bought “Car95” or Car NT”. But then you would have to buy more seats.

5. If you try to get your car to a mechanic, you’d make a long distance call, be put on hold for three or four hours, when you finally got the mechanic, you’d be told how to fix it yourself, and mechanic would hang up before you even tried his or her suggestions.

6. People would get excited about the “ new” features in Microsoft cars, forgetting completely they had been available in other cars for many years.

7. The airbag system would say: “Are you sure?” before going off.

8. Every time GM introduced a new model car, buyers would have to learn how to drive all over again because none of the controls would operate in the same manner as the old car.

9. Microsoft cars would have a special radio/cassette player which would only be able to listen to Microsoft FM, and play Microsoft Cassettes.

10. If you couldn’t afford to buy a new car, then you could just borrow your friends and then copy it.

11. You’d press the “start” button to shut off the engine.

46. The purpose of writing this article is ______.

A. to state the advantages of Microsoft in making cars

B to inform that Microsoft will make cars in the future.

C. To compare cars made by GM with those made by Microsoft

D. To make fun of the disadvantages of Microsoft’s products

A. would be safer than the old one

B. would become useless in case of an accident

The home computer industry has been growing rapidly in the United States for the last ten years . Computers used to be large, expensive machines that were very difficult to use . But scientists and technicians have been making them smaller and cheaper while at the same time they have been made easier to use. As a result, their popularity has been increasing as more people have been buying computers for their homes and businesses. Computers have been designed to store information and compute problems that are difficult for human beings to work out. Some have voices that speak with the operators. Stores use computers to keep records of their inventories(库存货物) and to send bills to their customers(顾客) . Offices use computers to copy letters, record business and keep in touch with other offices. People have been using computers in their homes to keep track of the money they spend.

One important new use for computers is for entertainment(娱乐). Many new games have been designed to be played on the computers. People of all ages have been playing these games, People also have been buying home computers to play computer games, watch movies and listen to concerts at home. They have become very popular indeed.

The earth’s most rich resource—water has become one of the most precious resources in the United States as rivers, lakes, and freshwater reservoirs are increasingly exploited for human use. Consequently, using precise farming techniques to refine “irrigation scheduling” is a research area of particular interest to Susan Moran, a researcher with the US department of Agriculture. She explains that in the southwest, irrigation is both difficult and expensive. There, she says, farmers have a tendency to over irrigate, spending both more time and money than is necessary.

“I’m trying to provide new information that could be used by farmers to schedule irrigations to improve their profitability and use less water,” Moran says. “Farmers often look at weather changes and then schedule irrigation based on that information. But if they had better information, they could use scientific models to compute more precisely how much water their crop is using. ”

Rather than guessing their crop’s potential need for water based upon weather changes, farmers can use remote sensors to measure how much water their crop is actually using. This would give them a more accurate measure of how much more water it needs.

Moran believes that if farmers are getting good and timely measurements of plant and air temperature, then they can program when and how much water to give each crop through an irrigation system. No more water would be used than needed, thus saving cost and conserving water.

Moran introduces one study she conducted in Arizona to investigate the use of remote sensing data for scheduling cotton irrigations. Typically, those farmers irrigate ten times per growing season, but evidence showed that some of those farmers could achieve basically the same harvest with only nine irrigations.

“In those cases, one less irrigation saved more than all the cost of remote sensing data,” she states. “Both irrigation and satellite remote sensing data are expensive. But then again many farmers are used to wording together as a group. They are used to sharing. I’m hoping they could do the same with remote sensing data—purchase one scene over a large area to cover many farms, which would further reduce the cost. ”

46. What does Moran think is the problem with farmers?

A. Over-used reservoirs. B. Precision farming.

C. Irrigation researches. D. Over-irrigation.

47. How can farmers get the new information about their crop?

A. To reschedule irrigation as required.

B. To watch weather changes regularly.

C. To use remote sensors as researchers suggest.

D. To use scientific models since computing is more reliable.

48. What do farmers check upon when they decide how much water each crop needs?

A. Profitability. B. Remote sensors. C. The cost. D. Air temperature.

49. What’s the purpose of Moran introducing the study she carried out in Arizona?

A. To investigate the use of remote sensing data.

B. To support her viewpoint in the previous paragraph.

C. To show how farmers can reap a harvest.

D. To criticize those farmers who used too much water.

50. What is among the best possible ways to help save farmers’ money?

A. Changing irrigation. B. Sharing sensing data.

C. Buying one computer. D. Extending the farms.
