Can you remember the first time you learned to ride a bike or drive a car?Learning these skills changed your life forever and opened up new horizons(視野).Learning about computers can be like learning how to ride a bike or drive a car.Once you have invested the time to master the skills,you will never go back to the old days.The new technology is simply too convenient and too powerful.
Technological developments through the years have enabled us to do more with less effort.We have continuously looked for better ways of doing things.Each invention and new development has allowed us to extend our capabilities.Today we see one of the most dramatic technologies ever developed—the computer.It extends the capabilities of our minds.
Computers have saved organizations millions of dollars. Furthermore,these same computer systems have opened up new opportunities that would have gone undiscovered or neglected.The computer may multiply what we can do,and the return on investment is high.The growth of computer usage is surprising. On the other hand,the computer can do serious damage.Invasion of privacy(侵犯隱私),fraud(欺詐),and computer-related mistakes are just a few shocking examples.?The computer is like a double-edged sword.It has the ability to cut us free from some activities,but it can also cut deep into profits,personal privacy,and our society in general.How it is used is not a function of technology.It is strictly a function of how people decide to use or misuse this new technology.The choice is yours,and only through a knowledge of computer systems will you be able to avoid the dangers while enjoying the many,many benefits of the computer age.

My bookshelves are full of dust — and with good reason. When it comes to cleaning that part of my home, I suffer from the most serious case of avoidance (回避反應(yīng)癥).
The thing is this: when I do set out to clean and re-organize my books, which seldom happens, I place myself into a really bad situation. No sooner do I take a title from the shelf, blow off the dust, and wipe down the cover than I find myself sitting on the floor with legs crossed and my back against the wall. Pretty soon books get piled up on my legs as I am reunited with old friends.
It is as if these books have voices, and each wants to say its piece. “Remember me? I was given to you when you went into the Navy, so that you would never lack for companionship,” one whispers. Another says, “I was your first book of poems, given to you before you learned to love poetry.” And a third, “I was the book that made history so attractive to you.”
Perhaps the greatest pleasure of re-organizing my books are the surprises — or better said, reunions — that occur. During my latest book-cleaning adventure, I found one that had fallen behind the shelf: “Tales of Edgar Allan Poe.” Not an unusual title, but the words written on the first page made it very special: “With Love from Mom and Dad, Christmas 1965.” What’s this? A book on the physics of lasers(激光). It is filled with mathematical statements, and I had bought it at a library sale when I was 12, not long after the laser had been invented. I couldn’t understand a bit of it, but I did learn what “l(fā)aser” meant.
What I end up with when I empty my bookshelves is a cross-section (橫剖面) of my personal history. It’s like a road cut where one sees all the layers of rock going back through time to the beginning of the simplest life forms. The books I’ve read — and kept — are not just old friends. They are my résumé.
50. What could be said about the author?
A. He is too busy to tidy up his bookshelves.
B. He considers his books treasured possessions.
C. He has made a lot of notes in his books.
D. He is a lover of science books.
51. By saying that his books have voices, the author means ________ .
A. they bring back happy memories
B. they are recorded in human voice
C. they say a lot about human history
D. they offer good topics for discussion
52. What does the author enjoy most from re-organizing his books?
A. Finding some missing books.
B. Putting books in good order.
C. Learning something new from the books.
D. Rediscovering interesting stories behind some books.
53. The underlined word “résumé” in the last paragraph probably means ______.
A. personal history         B. precious notes
C. good companion        D. simple life forms

Pulling heavy suitcases all day in the summer is hard work, especially when you’re a thin 14-year-old. That was me in 1940—the youngest and smallest baggage boy at New York City’s Pennsylvania Railway Station.
After just a few days on the job, I began noticing that the other fellows were overcharging passengers. I’d like to join them, thinking, “Everyone else is doing it.”
When I got home that night, I told my dad what I wanted to do. “You give an honest day’s work,” he said, looking at me straight in the eye. “They’re paying you. If they want to do that, you let them do that.”
I followed my dad’s advice for the rest of that summer and have lived by his words ever since.
Of all the jobs I’ve had, it was my experience at Pennsylvania. Railway Service that has stuck with me. Now I teach my players to have respect for other people and their possessions. Being a member of a team is a totally shared experience. If one person steals, it destroys trust and hurts everyone. I can put up with many things, but not with people who steal. If one of my players were caught stealing, he’d be gone.
Whether you’re on a sports team, in an office or a member of a family, if you can’t trust one another, there’s going to be trouble.
小題1:What can be inferred about the baggage boys?
A.They could earn much, but they had to work hard.
B.Many of them earned money in a dishonest way.
C.They were all from poor families.
D.They were all thin, young boys.
小題2: What does the father’s advice imply?
A.It is wrong to give more pay to the passengers.
B.Don’t believe them if they are paying you more.
C.Don’t follow others to overcharge the passengers.
D.It is difficult to work hard and live as an honest boy.
小題3:The writer can’t put up with stealing because he thinks that ___.
A.it is a totally shared experience
B.it is considered as the most dangerous
C.it does great harm to human relationship
D.it may lead to the loss of his sports team
小題4:It can be concluded from the text that ___.
A.his father’s advice helped him to decide which job to take up
B.working in the sports team was his most important experience
C.he learnt much from his shared experience with his team members
D.his experience as a baggage boy had a great influence on his latter life

When I was about 12, I had an enemy, a girl who liked to point out my shortcomings.
Week by week her list grew: I was very thin; I wasn’t a good student; I talked too much; I was too proud and so on.. I tried to bear all these all these things as long as I could. At last, I became very angry. I ran to my father with tears in my eyes.
He listened to me quietly, then he asked, “Are the things she said true or not? Janet, didn’t you ever wonder what you are really like? Well, you now have the girl’s opinion. Go and make a list of everything she said mark the points that are true. Pay no attention to other things she said.”
I did as he told me. To my great surprise, I discovered that about half of the things were true.
some of them I couldn’t change (like being very thin), but a good number I could and suddenly I wanted to change. For the first time I got a fairly clear picture of myself.
I brought the list back to Daddy. He refused to take it, “That’s just for you,” he said. “ You know better than anyone else, the truth about yourself. But you have to learn to listen, not just closing your ears anger and feeling hurt . When something said about you is true, you’ll find it will be of help to you. Don’t shut your ears. Listen to other people’s opinions, but hear the truth and do you know is right thing to do.”
Daddy’s advice returned to me at many important moments. IN my life, I’ve never had a better piece of advice.
小題1:Which do you think would be the best title for this passage?
A Not an Enemy, but a Best Friend
B The Best Advice I’ve Ever Had
C My Father
D My Childhood
小題2:What does “ week by week her list grew” mean?
A Week by Week, my shortcomings grew more serious.
B She had made a list of shortcomings and kept on adding new ones to it so that it was growing longer and longer.
C I was having more and more shortcomings as time went on.
D Week by week she discovered more shortcomings of mine and point them out.
小題3:Why did her father listen to her quietly?
A Because he believed that what her daughter’s enemy said was mostly true.
B Because he had been so angry with his daughter’s shortcomings that he wanted to show this by keeping silent for a while.
C Because he knew that his daughter would not listen to him at that moment.
D Because he wasn’t quite sure which girl was telling the truth.
小題4: What did the father do after he heard his daughter’s complaint?
A He told her not pay any attention to what her “enemy” said
B He criticized her and told her to overcome her shortcomings.

Recently I was invited to a friend’s house for supper —and had a meal I have never had before.
All the friends invited were a little surprised. It’s not that Ben is unsociable, or a bad cook, but it’s just that he never   21  more than he has to. So how come he was inviting us round for a meal? Had he bought something   22  for his friends? He greeted us at the door and showed us into his dining room where a   23 _ table was waiting for us.“Nothing but the best for my friends!”said Ben. We all sat down and looked   24   at each other —what was he up to?
Ben returned with four bowls of hot soup. “It’s a mixture of carrots, potatoes and tomatoes,”said Ben. The next   25  was also a little strange in that we didn’t quite know what it was again. It’s just another mixture of vegetable.
As we ate we chatted and finally the   26   turned back to what we were eating. ”Was there a recipe (食譜) for this,” asked Marina, “or did you   27   it up?” Ben put his fork down. “What I cooked depended on what I could find.” Marina was surprised. “But you can find anything in supermarkets these days.” “But there’s 28  choice in what you can find outside supermarkets,” he replied.
Seeing that we had all finished the food, Ben decided to tell the truth. He had read recently that supermarkets usually throw away 5 percent of their food every day. So Ben decided to look inside his local supermarket bins. There he found food that was slightly out of __29 , boxes of throw-away vegetables and fruit.
So Ben had successfully provided a decent (體面的) meal for his friends, and made us aware of the fact that there are many poor people who need the food, but the amount of food thrown away is enough to   30   millions of people.
