  When I was a boy of twelve, something stopped me forever from putting any wild creatures in a cage.

  We lived in a village.Every evening the mockingbirds(仿声鸟)would come and   1   in the trees and sing.No musical instruments can produce a more   2   sound than the songs of the mockingbird.

  I decided to   3   a young bird and keep it in a cage so that I would have my own private   4  .

  Finally I managed to catch   5   and put it in a cage.At first, the bird moved wildly about in the cage, but at last it   6   in its new home.I felt very pleased   7   myself and looked forward to some beautiful   8   from my little musician.

  On the second day, my new pet's   9   flew to the cage with something in her mouth.The baby bird   10   everything she brought to it.I was pleased to see this.  11  , the mother knew better than I about how to   12   her baby.

  The following morning   13   I went to see how my bird was doing, I was shocked to find it on the floor of the cage,   14   I had taken good care of it, but   15   had happened?

  Arthur Wayne, a famous scientist, happened to be visiting my father at the time.Hearing me crying over the death of my bird, he   16   what had happened."A mother mockingbird, finding her young in a cage, will sometimes bring it   17   food.She thinks it better for her young to   18   than to live in a cage."

    19   then I have never caught any living creature and put it in a cage.All living creatures have a   20   to live free.

Imagine a classroom missing the one thing that's long been considered a necessary part to reading and writing paper.No notebooks,no textbooks,no test paper.Nor are there any pencils or pens,which always seem to run out of ink at the critical moment.A“paperless classroom”is what more and more schools are trying to achieve.

Students don't do any handwriting in this class.Instead,they use palm size,or specially?designed computers.The teacher downloads texts from Internet libraries and sends them to every student's personal computer.

Having computers also means that students can use the Web.They can look up information on any subject they're studying from maths to social science.

High school teacher Judy Herrell in Florida,US,described how her class used the Web to learn about the war in Afganistan(阿富汗) over one year ago.

“We could touch every side of the country through different sites from the forest to refugee camps(难民营),”she said.“Using a book that's three or four years old is impossible.”

And exams can go online too.At a high school in Tennessee,US,students take tests on their own computers.The teacher records the grades on the network for everyone to see and then copies them to his own electronic grade book.

A paperless classroom is a big step towards reducing the waste of paper.High school teacher Stephanie Sorrell in Kentucky US said she used to give about 900 pieces of paper each week to each student.

“Think about the money and trees we could save with the computers,”she said.But,with all this technology,there's always the risk that the machines will break_down.So, in case of a power failure or technical problems, paper textbooks are still widely available(可用的) for these hi?tech students.

1.What does the part of the last but one sentence in the first paragraph,“run out of ink at the critical moment” mean?

A.Pens may not write welt at the critical moment.

B.Pens get lost easily,so you may not find them at the critical moment.

C.Pens may have little or no ink at the critical moment.

D.Pens use ink,while pencils don't.

2.In a paperless classroom, what is a must?

A.Pens.           B.Computers.

C.Information.        D.Texts.

3.The high school teacher,Judy Herrell,used the example of her class to show that________.

A.the Web could take them everywhere

B.the Web taught them a lot

C.the Web is a good tool for information

D.the Web,better than the textbooks,can give the latest and comprehensive(全面的) information

4.The paperless classrooms will benefit ________ the most.

A.students      B.teachers 

C.trees       D.computers

5.What does the phrase in the last paragraph,“break down”,mean?

A.Break into pieces.     B.Stop working.

C.Fall down.        D.Lose control.

  Farmer Ed Rawlings smiles as he looks at his orange trees. The young oranges are growing well in Florida's weather. Warm sunshine and gentle rains, along with Ed Rawlings' expert care, will produce a good crop of oranges this year.

  But Ed has to fight against Florida's changeable winter weather. In January and February, temperatures can destroy Ed's entire orange, crop. Having farmed in Florida for the past 35 years, Ed Rawlings is prepared for the frosts(霜). When temperatures drop below freezing, Ed tries to save his crop by watering his orange trees. The water freezes and forms a thin layer (层)of ice on the trees. Strange as it may sound, this thin layer of ice actually keeps the fruit warm.

  What happens is simple. When the trees are watered, the water loses heat and becomes ice. The warmth of the heat it loses is sucked in by the fruit and keeps its temperature at a safe level. Ed Rawlings has effectively used this method(方法)to save many orange crops.

  But Ed still faces some difficulties. The trees should be watered at the exact moment the temperature drops to the freezing point. Also, just the right quantity of water must be used. Too much water can form a thick layer of ice that will break the trees' branches. Another difficulty is that wind blows away the heat. So Ed has to worry about not only when but also how often his trees should be watered, and how much water should be used.

  Computer technology may help Ed Rawlings with some of these worries. With equipment, air and soil temperatures and wind speed can be measured. The information is fed into a computer which can tell when temperatures drop to freezing. The computer can correctly decide the quantity of water to be used and how frequently the trees should be watered. Ed Rawlings will find looking after his orange trees a lot easier with the help of a computer, and we'll all have the benefits(or advantages)of computer-age oranges.

1. The passage is mainly about _____ .

A.a farmer's expert care for his orange trees 

B. the different uses of computers

 C. growing oranges in Florida's changeable weather

2. Ed tried to protect his crop by _____ .

 A. using a wind machine to drive away the cold air

3. In the writer's eyes, computers _____ .

A.are too expensive for small farmers

B. can be a valuable tool for the farmer

 C. can be used to help oranges grow bigger    

 D. cannot take the place of the farmer's experience and judgement

4. Which of the following is NOT NECESSARY for Ed Rawlings to do?

  A. He should water the orange trees as soon as the temperature drops to the

    freezing point.

  B. He should decide the quantity of water for the orange trees.

  C. He has to water the orange trees more often in January and February.

  D. He has to judge how often he should water the orange trees.

5. According to the passage, the computer technology can _____ .
