Ⅱ    閱讀(共兩節(jié),滿分50分)

第一節(jié) 閱讀理解(共20小題;每小題2分,滿分40分)

       閱讀下列短文,從每題所給的A、B、C和D項中,選出最佳選項,并在答題卡上將該項涂黑。

  Even plant 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 (紅外線)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 (殺蟲劑)spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest (害蟲)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 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 ff Paley finds the financial backing which he failed to obtain 10 years ago.

26.Plants will emit an increased amount of heat when they are______________.

A. sprayed with pesticides          

B. facing an infrared scanner

C. in poor physical condition        

D. exposed to excessive sun rays

27.In order to apply pesticide spraying precisely, we can use infrared scanning to____________.

A. estimate the damage to the crops  

B. measure the size of the affected area

C. draw a color-coded map         

D. locate the problem area

28.Farmers can save a considerable amount of pesticide by______________.

A. resorting to spot-spraying       

B. consulting infrared scanning experts

C. transforming poisoned rain      

D. detecting crop problems at an early stage

29.The application of infrared scanning technology to agriculture met with some difficulties

_______________.

A. the lack of official support      

B. its high cost

C. the lack of financial support      

D. its failure to help increase production

30.Infrared scanning technology may be brought back into operation because of_____________.

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

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

  C. the forceful promotion by the Department of Agriculture

  D. full support from agricultural experts

Today almost everyone knows computers and the Internet. If I ask you “What is the most important in your life?”, maybe you will say “Computers and the Internet.”

The first computer was made in 1946. It was very big but it worked slowly. Today computers are getting smaller and smaller. But they work faster and faster. What can computers do? A writer has said, “People can’t live without computers today.”

The Internet came a little later than computers. It is about twenty-five years later than computers. But now it can be found almost everywhere. We can use it to read books, write letters, do shopping, play games or make friends.

Many students like the Internet very much. They often go into the Internet as soon as they are free. They make friends on the Internet and maybe they have never seen these friends. They don’t know their real names, ages, and even sex (性別). They are so interested in making the “unreal friends” that they can’t put their heart into study. Many of them can’t catch up with others on many subjects because of that.

We can use computers and the Internet to learn more about the world. But at the same time, we should remember that not all the things can be done by computers and the Internet.

The Internet cannot be used for __________

       A. studying         B. shopping      C. thinking         D. playing

When the computer was invented, it was__________

       A. large and worked quickly           B. small and worked slowly

       C. large but worked slowly            D. small but worked quickly

The Internet was born in about __________

       A. 1960           B. 1970                C. 1980     D. 1985

Which of the following is true?

       A. Few students like going into the Internet.

       B. Students use the Internet to make “unreal friends”.

       C. These “unreal friends” often meet each other.

       D. Students know the friends on the Internet very well.

What does the writer think of the Internet?

       A. It is wonderful.              B. It can make students study harder.

       C. It is not good for students.      D. It is helpful, but we can’t do everything on it.
