I never thought I would have a life-changing experience at Wal-Mart.

Although my thoughts were only on speed, the checkout line I was standing in wasn't moving as quickly as I wanted, and I glanced toward the cashier.

There stood a man in his seventies, wearing glasses and a nice smile. I thought, well, he's an old guy!

For the next few minutes I watched him. He greeted every customer before scanning the items. Sure, his words were the usual, "How's it going?" But he did something different--he actually listened to people. Then he would respond to what they had said and engage them in brief conversation.

I thought it was odd. I has grown accustomed to people asking me how I was doing simply out of robotic conversational habit. After a while, you don't give any thought to the question and just mumble something back. I could say, "I just found out I have six months to live," and someone would reply, "Have a great day!"

But that wasn't the end.

He gave them the change, walked around the counter, and extended his right hand in an act of friendship. He looked the customers in the eyes. "I sure want to thank you for shopping here today," he told them. "You have a great day. Bye-bye."

The looks on the faces of the customers were priceless. There were smiles and some sheepish grins. All had been touched by his simple gesture--and in a place they never expected. They would gather their things and walk out, smiling.

Of course, he did the same to me and I got to know his name--Marty.

Who was that guy? It was as if Sam Walton had come back from the dead and invaded this old guy's body.

 I had never walked away from that shop feeling like that.

1.What was most customers' reaction to Marty's behavior?

A. They thought it priceless.

B. They thought it awful and odd.

C. They felt somewhat offended.

D. They were in some way moved.

2.The checkout line the writer was standing in moved slower than expected because______

A. the cashier did more than scanning the items

B. the cashier couldn't work as fast as others

C. there were some big purchases

D. the writer was not patient enough

3.What can we infer about Sam Walton?

A. He might be Marty's father or grandfather.

B. He might have died while working in the market.

C. He might be friendly and devoted to Wal-Mart.

D. He might have come back from the dead once before.

4.According to the writer, when common people ask you "How's it going?"

A. they are just practicing their conversation ability

B. they are inquiring about your private information

C. they don't expect to hear any negative answers

D. they don't really care what you may answer

5.What does the writer intend to express through the text?

A. Our everyday life is always full of surprises.

B. Being different is a good way of doing business.

C. A little positive action can make a big difference.

D. Most customers enjoy being treated this way.

High Speed Book Scanner
Simply turning pages of a book quickly may not seem like the best way to scan it. A Japanese research group at Tokyo University has created new software that allows hundreds of pages to be scanned within minutes. Scanning text is normally a boring process with each page having to be inserted into a scanner, but the team led by Professor Masatoshi Ishikawa uses a high speed camera that takes 500 pictures a second to scan pages as they are turned by workers.
Normal scanners can only scan the information that is actually before them on the page. This high speed book scanner uses a camera that captures pages at 1000fps as they are turned. A system built in allows it to automatically correct any changes to the text due to the page bending as well as light differences due to shadows. “It takes a shot of the shape, then it calculates the shape and uses those calculations to film the scanning,” Ishikawa said, explaining the system used to reconstruct the original page.
The current system is able to scan an average 250-page book in a little over 60 seconds using basic computer hardware. While it now requires extra time to process the scanned images (影像), the researchers hope to eventually make the technology both faster and much smaller. “In the more distant future, once it becomes possible to put all of this processing on one chip (芯片) and then put that in an iPad or iPod, one could scan just using that chip. At that point, it becomes possible to scan something quickly to save for later reading,” Ishikawa said.
Being able to scan books with an iPhone may be further off, but Ishikawa says that a commercial version of the large-scale computer based scanning system could be available in two or three years. While the technology has the potential to take paper books into the digital age, it remains to be how publishers will react to people scanning their books while just turning pages quickly.
【小题1】According to the passage, the advantage of the new scanning software is that ______.

A.there is no need to scan every page
B.it can work much more effectively
C.no manpower is needed in operating the scanner
D.it can make the scanning process more interesting
【小题2】According to Ishikawa, the scanner works by_____.
A.changing the shape of the images
B.reducing the size of the images
C.reconstructing the original page
D.scanning several pages at the same time
【小题3】What is Ishikawa’s attitude towards the development of the scanning system?
A.Optimistic.B.Uncertain.C.Disapproving.D.Cautious.
【小题4】What does the underlined sentence mean?
A.People will get any book they like more easily.
B.Publishers will refuse to comment on the new software.
C.Publishers will probably not welcome the new software.
D.People won’t need to buy books any more with an iPhone.

A

  Ask Dr ? Jeffers

This month Dr. Jeffers is answering questions about the human brain and how it works.

Dear Dr. Jeffers,

One of my colleagues, Felix Moeller, told me that scientists are learning to use computer to ‘read minds’. Is there any truth to this story/

—Jane Leon, New York, USA

Dear Ms. Leon,

Well, a lot of research is being conducted in this area, but so far, the brain scanning equipment and corresponding computer programs haven’t been able to actually read thoughts. In one experiment, test subjects(受试者)were connected to scanning equipment and shown two numbers on a screen. They were then asked to choose between adding or subtracting(减)the two numbers. Using this method, researchers were able to follow brain processes and make the correct assumptions(假设)70 percent of the time. It’s not quite mind reading, but it’s certainly a first step.

—Dr. J.

Dear Dr. Jeffers,

My three-year-old son loves it when I dig my fingers into his sides and tickle (胳肢)him until he laughs uncontrollably. The other day I noticed him trying to tickle himself but he couldn’t do it. Why not?

—Glenn Lewis, Vancouver, Canada

Dear Mr. Lewis,

It’s because of how the brain works. The brain is trained to know what to pay attention to and what to ignore. It causes us to ignore physical feelings we expect to happen, but it causes a mild panic reaction when there is an unexpected feeling. For example, you don’t notice how your shoulder feels while you’re walking down the street. But if someone comes up behind you and touches you lightly on the shoulder, you may jump in fear. It’s that unexpected part that causes the tickle reaction.

—Dr. J.

46. What can we learn from the answer to the first question?                          

A. Some equipment is able to read human minds.

B. Some progress has been made in mind reading.

C. Test subjects have been used to make decisions.

D. Computer programs can copy brain processes.

47. People laugh when tickled by others because the feeling is _______.                 

A. unexpected        B. expected        C. comfortable        D. uncomfortable

48. Who has got a little child according to the text?                                  

A. Ms. Leon          B. Mr. Lewis        C. Mr. Moeller        D. Dr. Jeffers

49. According to the text, Jeffers is probably _______.                               

A. a computer programmer                B. a test subject

C. a human brain expert                   D. a medical doctor
