15.Bar codes are one way that the U.S.Postal Service streamlines mail of the wrong hands.A letter that comes without a bar code or cancelled stamp might not have been processed by the U.S.Postal Service and it might indicate that something's fishy.(可疑的)Can you decode a bar code the way the U.S.Postal Service can?
Here's How
1.Here's how to read the bar code on your letter.
•Most U.S.letter bar codes have bars of two lengths:long and short.
•Every bar code should start and end with long bars; ignore those.
•Look at the rest of the bars in groups of five,starting with the second bar.Each group of five represents one digit.(数字)
2.Here's how to figure out what those digits are.
•The five bars stand for one of these numbers:7,4,2,1,0.
•Some genius figured out that this range would allow you to come up with the digits 0to 9.You do it by adding the numbers of the long bars together.
Say you have this bar code:
Here,the 4and 2places have long bars.Added together,they total 6,so this bar code stands for 6.
Say you have this bar code:
The 1and 0places have long bars.Added together,they total 1,so this bar code stands for 1.
Say you have this bar code:
The 7and 4pieces have long bars.Added together,they total 11,but there is no 11in this system,so this bar code stands for 0.
3.Now let's look at the bar code on a letter.

Ignore the first and last bars of the whole bar code.Then look at the next 20bars to find the zip code (0680).The next two sets of five bars give your mail carrier's number (10153).The rest of the bars in the bar code indicate the house or maibox number.The house number is 32.

63.Why does US Postal Service just use five numbers for the five bars?D
A.They are easy to read.            B.They are ohosen only by accident.
C.They can stand for the long bars. D.They are enough to make ten digits.
64.Which of the following bar codes otands for"7"according to the text?B
A.   B.  C.  D.
65.According to the text,we know thatC.
A.the bar code often beings with a short bar
B.the last short her is often ignored
C.the mail route should follow the zip code
D.the bar code can show your house color
66.The purpose of the text is to let us know how toB.
A.create a bar code  B.recognize a bar code
C.send a letter      D.make the maibox safe.

分析 本文为应用文,介绍了如何从邮局的条码中找到对应的数字及地址.

解答 63-66 DBCB
63.答案D.细节理解题.根据第二部分第二段"Some genius figured out that this range would allow you to come up with the digits 0to 9"可知,这五个数字就足够组成0--9之间的数了.故选D.
64.答案B.推理判断题.根据第二部分"Say you have this bar code:Here,the 4and 2places have long bars.Added together,they total 6,so this bar code stands for 6."和"Say you have this bar code:The 1and 0places have long bars.Added together,they total 1,so this bar code stands for 1."可知,五个数字的顺序是不变的,把最高那条代表的数字加起来就是这个条码代表的数字.A选项最高条码为7,4,代表11,根据"The 7and 4pieces have long bars.Added together,they total 11,but there is no 11in this system,so this bar code stands for 0."可知,A为0.B最高条码为7,0,加起来为7.C最高条码为7,2,密码为9.D最高条码为2,0,密码为2.故答案选B.
65.答案C.推理判断题.根据第三部分第一段"Then look at the next 20bars to find the zip code (0680)."可知,邮政编码与条码要一致.故选C.
66.答案B.写作目的题.根据文章第一段"Can you decode a bar code the way the U.S.Postal Service can?Here's How"可知,本文主要讲解如何从邮局的条码中找到对应的数字及地址.故选B.

10.The Friday after the American holiday of Thanksgiving is called Black Friday.It's said that it's the day that store ledgers(分类账)move into the black and companies become profitable.On that day,retailers slash(砍) prices to get consumers to buy.It is also a time when many Americans start their Christmas shopping.VOA's Elizabeth Lee tells us how the economy may affect consumers on that bargain day.
 This day should be a shopper's dream."It's just the deals,the sales and everything you can get for a lesser price,"said Sandy Thomas,a shopper.But it's a nightmare for others."I think it's crazy.I've done all of my shopping throughout the week so I don't have to go out on Friday,"she said.It's called Black Friday,the start of the traditional Christmas shopping season in the United States.Every year it's the day after the Thanksgiving holiday.Stores open before sunrise and there are deep discounts everywhere you look.
Last year a crowd of bargain-hunters killed a Wal-mart worker in a New York suburb.This year,many stores are increasing security while they slash prices."This is a huge time for the retail stores,"said Fred Joutz from George Washington University."This is when they begin making their profits for the year."
Economics professor Fred Joutz says how Americans spend the weekend after Thanksgiving is a good indication of how consumers feel about the future.
With the unemployment rate above 10 percent,Joutz says Americans are saving more and spending less.Some retailers are attracting consumers by opening on Thanksgiving Day,when shops are traditionally closed.Other stores open their doors anywhere from midnight to four in the morning.
And shoppers will be lining up in front of the doors in order to be one of the first ones to walk through and get a big discount.Electronics like flat screen TVs are usually the first items to go.Sandy Thomas says it's an annual family tradition and well worth it."I just save maybe half of what I would have spent on a regular,you know,shopping trip,"she said.
Economists say U.S.consumers will spend money this Black Friday,but they will spend it more carefully.
71.By saying"This day should be a shopper's dream",the writer meansD.
A.shoppers have longed for this day for a long time
B.the shops will be very crowded on that day
C.the shops will keep open until the daybreak of next day
D.shoppers can buy many items at low prices on that day
72.Why are many stores increasing security according to the passage?C
A.Because there are too many people saving more and spending less.
B.Because it's a time when they begin making their profits for the year.
C.Because last year a crowd of bargain-hunters caused an accident.
D.Because many stores open their doors from midnight to four a.m.
73.From the passage we know thatA.
A.Christmas shopping is traditional time and this year it is no exception.
B.Electronics like flat screen TVs are usually least discounted.
C.The economy only affects consumers on that bargain day.
D.Thanksgiving is a good indication of how consumers feel about the future.
74.We can find this passage inC.
A.a science fiction                       B.a travel brochure
C.an economic research report             D.a book on psychology
75.Why American people call it a black day?B
A.Because they organize activities in honor of some great person.
B.Because there are too many people going out shopping for Christmas.
C.Too many people are celebrating Thanks giving.
D.The sky is black that day.

20.According to sociologists,there are several different ways in which a person may become recognized as the leader of a social group in the United States.In the fanfily traditional cultural patterns confer (~z~,) leadership on one or both of the parents.In other cases,such as friendship groups,one or more persons may gradually emerge as leaders,although there is no formal process of selection.In larger groups,leaders are usually chosen
formally through election or recruitment.
Although leaders are often thought to be people with unusual personal ability,decades of research have failed to produce consistent evidence that there is any category of"natural
leaders."It seems that there is no set of personal qualities that all leaders have in common;rather,virtually any person may be recognized as a leader if the person has qualities that meet the needs of that particular group.
Furthermore,although it is commonly supposed that social groups have a single leader,research suggests that there are typically two different leadership roles that are held by different individuals.Instrumental leadership is leadership that emphasizes the completion of tasks by a social group.Group members look to instrumental leaders to"get things done."
Expressive leadership,on the other hand,is leadership that emphasizes the collective well-beings of a social group's members.Expressive leaders are less concerned with the overall goals of the group than with providing emotional support to group members and attempting to minimize tension and conflict among them.Group members expect expressive leaders to maintain stable relationships within the group and provide support to individual members.
Instrumental leaders are likely to have a rather secondary relationship to other group members.They give orders and may discipline group members who prohibit attainment (达到) of the group's goals.Expressive leaders cultivate a more personal or primary relationship to others in the group.They offer sympathy when someone experiences difficulties or is subjected to discipline,are quick to lighten a serious moment with humor,and try to resolve issues that threaten to divide the group.As the difference in these two roles suggests,expressive leaders generally receive more personal affection from group members;
instrumental leaders,if they are successful in promoting group goals,may enjoy a more distant respect.

72.Which of the following statements about leadership can be inferred from paragraph 2?B
A.Few people succeed in sharing a leadership role with another person.
B.A person who is an effective leader of a particular group may not be an effective leader in another group.
C.A person can best learn how to be an effective leader by studying research on leadership.
D.Most people desire to be leaders but can produce little evidence of their qualifications.
73.The passage indicates that instrumental leaders generally focus onC.
A.ensuring harmonious relationships
B.sharing responsibility with group members
C.achieving a goal
D.identifying new leaders
74.A"secondary relationship"between a leader and the members of a group could best be described asA.
A.distant                              B.enthusiastic
C.sympathetic                          D.personal
75.What does the passage mainly discuss?D
A.The problems faced by leaders.
B.How leadership differs in small and large groups.
C.How social groups determine who will lead them.
D.The role of leaders in social groups.

7.The cheapest room and board in Jefferson City,Missouri,over the weekend was at the county jail(监狱),and 170 people gladly checked in.Cole County charged $ 30 a night for anyone who volunteered to go behind bare on Friday or Saturday night.So officials could give the new jail a test run before it opened for real this week.People from three states spent the night at the jail,including some lawyers and a couple celebrating their first anniversary. 
"It was something they could experience without having to get a criminal record,"Cole County Sheriff (治安官)Greg White said."They spent the night and gained all understanding that they would not want to ever do this again."
Jailers tried to give the citizens the full experience.They were told to give up their jewelry,cell phones,and other personal belongings.They were booked and photographed and led into the jail commons. They could keep their cell doors open,but that trapped feeling was still there because me outer room doors were locked,said Bob Watson,60,a reporter for the Jefferson City News-Tribune who spent Friday night at the jail."While it was not a true copy of jail,you got some sense of what it's like to hear that door lock behind you,"Watson said.
Two other feelings were boredom and a lack of choice,illustrated by the television being left on one channel and drowned out anyway by everybody talking.
Bed was a steel bunk with a thin mattress (垫).Overhead,a 40-watt bulb stayed lit through the night in each cell.Handy for guards to see inmates,but not helpful to good sleep.How about the food?Dinner Friday night included cheesy pasta with turkey bits and coffee cake."I wouldn't pay for it in a restaurant,but you won't die trying to eat it,"Watson said.
56.The 170 people stayed in the county jail toA.
A.make a holiday                       B.get punishment                
C.do a research                        D.makemoney

A.The jailers performed their duty well.           
B.The jail's test run proved successful.
C.The 170 had the feeling of real prisoners.       
D.The 170 weren't treated as real prisoners.
58.The underlined phrase"illustrated by…"is used toC.
A.introduce a new topic                B.draw a conclusion             
C.give an example                      D.show the result
59.The 170 people were able toDin the county jail.
A.make phone calls                     B.sleep well            
C.go around freely                     D.chat with others

D.He didn't eat Mat all.

4.One night,I was partying in central London,near Piccadilly Circus.Running short of money,I set off to find the nearest ATM to withdraw some cash.At Shaftesbury Avenue,I saw a huge queue for one ATM machine,but no one was using the neighboring"hole in the wall".Assuming that the second machine was broken,I asked one queuing man if it was out of order.He replied,"It's working,but this one pays out twenties for tenners!"
So the reason for the weirdly long queue is that these folks wanted to"double their money"by getting£20 notes for each£10 note requested.Being an honest man,I didn't hang about; I simply used the idle machine and walked off.
Last week,customers took similar advantage of Commonwealth Bank in Sydney,Australia.Following overnight maintenance,a computer virus caused CommBank's ATMs to fail to function properly and begin paying out extra money,with unrestricted withdrawals.They allowed customers with little or no cash in their accounts to withdraw large sums that they didn't have.After about 5½hours,CommBank managed to restart these ATMs and stop the flood of cash.
You stole your own cash!
By withdrawing money they didn't have in their accounts,some of these greedy customers have gone heavily overdrawn.News reports indicate that some people were withdrawing as much as AU$2,500 (£1,563)in a single dealing.
Alas,both CommBank and the New South Wales police said that they will use ATM records and cameras to track down those who took advantage of the error.As Detective Superintendent Col Dyson of the New South Wales police department warned,"People should realise that they don't have the right to take that money and are committing a criminal offence if they keep it."
What about overpayments?
What about when you key in a£20 withdrawal and you get two£20 notes,not two£10 notes?
In English law (covering England and Wales),you have the right to keep money paid to you in error"under mistake of fact",but only if you honestly believe that the money is yours.
However,if you requested£20,got£40 and£40 was allowed to be lent to you,then the cash is yours to keep,as neither you nor the bank has suffered any loss.
