Ⅱ.阅读理解
How you end a computer session depends on how you use the computer, your views on energy conservation (能源的节约),
and what you have been told about how your decision will affect your investment’s longevity: will frequent starting and stopping cause its circuits(电路) to burn out sooner?
Rest easy, your computer is more likely to be damaged by a virus picked up from the Internet than by being turned off and on too much. They are also energy－efficient: such efficiency has reached the point where most computers place themselves in sleep mode if they remain idle (闲置的) for a certain period of time. So your computer will likely slip into sleep mode anyway, even if you leave it on overnight.
Sleep mode itself, once a pretty unreliable option—you never knew if you would be able to wake your computer without having to reboot (重新启动)
it—has been vastly improved with newer operating systems. If you want your computer to consume as little energy as possible when not in use, shut it down. If you want it to consume zero energy, you’re going to have to unplug (拔去……的电源插头) it.
Your computer can be in only three states: on, sleep or off—each of which draws some level of electric current.A computer that is “on” will either be actively processing information or sitting idle, depending on whether the user is typing a document, reading an e－mail or has stepped away briefly. The amount of wattage (瓦特数) drawn when the computer is on varies greatly depending on whether it is a laptop or a desktop computer. The latter uses more energy because desktop power supplies are less efficient and require a separate and often larger, power－hungry monitor.
It also varies based on the type of work being done: complex calculations requiring intensive processing are more power－hungry, whereas writing or Web browsing consumes far less electricity.
16．If sleep mode goes wrong, what will probably happen to your computer?
A．It will consume as little energy as possible.
B．It is more likely to be damaged by a virus picked up from the Internet.
C．It will have to be rebooted when used again.
D．It has to be shut down and unplugged.
17．Which of the following is NOT mentioned in the text that contributes to the different amount of energy a computer consumes?
A．Whether it is a laptop or a desktop computer.
B．What kind of work the computer is dealing with.
C．The choice of how you use your computer.
D．Whether the operating systems are new.
18．When does a computer consume the most energy?
A．When we let it remain idle.
B．When we use it to do complex calculations.
C．When we use it to type some documents and e－mail.
D．When we use it for surfing the Internet.
19．The reason why a desktop computer uses more energy than a laptop computer is that________.
A．a desktop computer’s monitor is separate and often larger
B．a desktop computer is larger than a laptop computer in size
C．a desktop computer performs more kinds of work than a laptop computer
D．a desktop computer is not energy－efficient
20．Which of the following is implied in the first two paragraphs?
A．Frequent starting and stopping can damage a computer.
B．A computer’s longevity depends more on the proper way you use it.
C．A virus picked up from the Internet is likely to damage a computer.
D．The more often you use a computer, the more smoothly it works.
Ⅲ.阅读简答
A student was one day taking a walk with a professor. As they went along, they saw lying in the path a pair of old shoes, which they supposed to belong to a poor man working in a field nearby.
The student turned to the professor, saying: “Let us play the man a trick: we’ll hide his shoes, and place ourselves behind those bushes, and wait to see his perplexity(困惑) when he cannot find them.”
“My young friend，” answered the professor, “we should never amuse ourselves at the expense of the poor. But you’re rich, and may give yourself a much greater pleasure by means of the poor man. Put a coin into each shoe, and then we’ll hide ourselves and watch how the discovery affects him.”
The student did so, and they both hid somewhere nearby. The poor man soon finished his work, and came across the field to the path where he’d left his coat and shoes. While putting on his coat, he put his foot into one of his shoes; but feeling something hard, he bent down to see what it was, and found the coin. Astonishment and wonder were seen upon his face. He picked up the coin, turned it round, and looked at it again and again. He then looked around but saw nobody. He now put the money into his pocket, and went on to put on the other shoe; but his surprise was doubled on finding the other coin. He was so touched that he fell upon his knees, and let out a loud thanksgiving, in which he spoke of his sick wife and his hungry children and the importance of the money to them.
The student stood there, deeply affected, and said to the professor, “You’ve taught me a lesson which I’ll never forget. I feel now the truth of those words, which I never understood before: ‘It is more blessed to give than to receive’．”
21．What did the student think of doing at the sight of the old shoes? (No more than 10 words)
________________________________________________________________________

22．Why didn’t the professor agree to the student’s the trick? (No more than 15 words)

23. How did the poor man feel when he found the coins? (No more than 7 words)

24. What is the purpose of the passage? (No more than 13 words)
