We’re all connected. You can send an e-mail message to a friend, and your friend can pass it on to one of his or her friends, and that friend can do the same, continuing the chain. Eventually, your message could reach just about anyone in the world, and it might take only five to seven e-mails for the message to get there.
Scientists recently tested that idea in a study involving 24,000 people. Participants had to try to get a message forwarded to one of 18 randomly(隨意地,隨機(jī)地) chosen people. Each participant started by sending one e-mail to someone they knew. Those who received it could then forward the e-mail once to someone they knew, and so on.
Subjects, who were randomly assigned by researchers from Columbia University in New York, lived in 13 countries. They included an Australian police officer, a Norwegian veterinarian, and a college professor.
Out of 24,000 chains, only 384 reached their goal. The rest petered out, usually because one of the recipients was either too busy to forward the message or thought it was junk mail.
The links that reached their goal made it in an average of 4.05 e-mails. Based on the lengths of the failed chains, the researchers figured out that two strangers could generally make contact in five to seven e-mails.
The most successful chains relied on casual acquaintances rather than close friends. That’s because your close friends know each other while your acquaintances tend to know people you don’t know. The phenomenon, known as the strength of weak ties, explains why people tend to get jobs through people they know casually but aren’t that close to.
So, start networking and instant messaging now. As they say in show business: It’s all about who you know.
小題1:If you want to get into touch with a stranger in the world, how many e-mails might it take for the message to reach him/her?
A.5 to 7B.18C.13D.384
小題2:Who does the word “subjects” refer to in the passage?
A.the 384 participants who lived in Australuia
B.the Norwegian veterinarians and college porfessors
C.the 24,000 people randomly assigned by reaearchers
D.the 18 people randomly chosen from 13 countries
小題3:What does the phrase “peter out” mean in the fourth paragraph?
A.die outB.pass awayC.disappearD.pick out
小題4:Why do people tend to get jobs more easily through casual acquaintances than close friends?
A.Because close friends don’t talk with each other so much.
B.Because casual acquaintances can help you know more people and make more friends.
C.Because close friends don’t spend so much time gathering together.
D.Because casual acquaintances are kinder and more willing to help others.

My husband is a born shopper. He loves to look at things and to touch them. He likes to compare prices between the same items in different shops. He would never think of buying anything without looking around in several different shops. On the other hand, I’m not a shopper. I think shopping is boring and unpleasant. If I like something and I have enough money to take it, I buy it at once. I never look around for a good price or a better deal. Of course my husband and I never go shopping together. Doing shopping together would be too painful for both of us. When it comes to shopping, we go our different ways.
Sometimes I ask my son Jimmy to buy some food in the shop not far from our home. But he is always absent-minded. This was his story.
One day I said to him, ” I hope you won’t forget what I have told you to buy.” “ No,“ said Jimmy. “I won’t forget. You want three oranges , six eggs and a pound of meat.”
He went running down the street to the shop. As he ran, he said to himself over and over again, “three oranges , six eggs and a pound of meat.”
In the beginning he remembered everything but he stopped several times. Once he saw two men fighting outside a clothes shop until a policeman stopped them. One of them was badly hurt. Then he stopped to give ten cents to a beggar. Then he met some of his friends and he played with them for a while. When he reached the shop, he had forgotten everything except six eggs.
As he walked home, his face became sadder and sadder. When he saw me he said, “I’m sorry, Mum. I have forgotten to buy oranges and the meat. I only remembered to buy six eggs, but I’ve dropped three of them.”
小題1:The husband likes shopping because _______.
A.he has much money.
B.he likes the shops.
C.he likes to compare the prices between the same items.

 Not everyone in the world requires the same amount of living space. The amount of space a person needs around him is a cultural (文化的) difference, not an economic one. Knowing your own psychological (心理的) space needs is important because they strongly affect your choices, including, for example, the number of bedrooms in the home. If you were brought up in a two-child family and both you and your sister or brother had your own bedrooms, the chances are if you have two children or more, that you also will offer separate bedrooms for them. In America, for example, they train people to want to have their own rooms by giving them their own rooms when they are babies. This is very unusual in the world. In many other countries, the baby sleeps in the same bed with his parents or in bed near them.
   The space in the home also shows a lot about psychological space needs. Some families gather closer to each other and the size of their house has nothing to do with it. Others have separate little corners where family members go to be alone.
   Although it is true that psychological space needs are not decided by economic reasons, they sometimes have to be changed a little because of economic pressure(壓力). It is almost impossible, however, to completely change your psychological space needs.
 
小題1:The first sentence in Paragraph 1 “Not everyone in the world requires the same amount          of space” means “______”.
A.Not two people need exactly the same amount of living space
B.Living space requirements are not always the same
C.The world requires the same amount of living space
D.Nobody needs a required amount of living space
小題2:Some families gather closer to each other at home than others because ______.
A.they have limited living space   
B.they are brought up in a large family
C.it satisfies(滿足) their psychological space needs
D.the children in the family sleep in the same bed with their parents
小題3:Which of the following is true according to the passage?
A.Americans are trained to live in the large rooms at birth.
B.Economic situation decides one’s amount of space needs.
C.People in different countries demand(need) different psychological space.
D.Knowing your psychological space needs is important, as it has effect on your future.
小題4:The best title for this passage is ______.
A.American Way of Living
B.Psychological Space
C.Space Needs in Different Countries
D.Psychological Space and Economic Pressure

Women are on their way to holding more than half of all American jobs. The latest government report shows that their share of nonfarm jobs nearly reached fifty percent in September.
Not only have more and more women entered the labor market over the years, but the depression has been harder on men. In October the unemployment rate for men was almost eleven percent compared to eight percent for women.
Industries that traditionally use lots of men have suffered deep cuts. For example, manufacturing and building lost more jobs last month. But health care and temporary employment services have had job growth. Both of those industries employ high percentages of women.
Thirty years ago, women earned sixty-two cents for every dollar that men earned. Now, for those who usually work full time, women earn about eighty percent of what men earn. And women hold fifty-one percent of good-paying management and professional jobs.
Yet a study released Thursday said men still hold about nine out of every ten top positions at the four hundred large companies in California. The results have remained largely unchanged in live years of studies from the University of California, Davis.
Also, a new research paper in the journal Sex Roles looks at the experiences of women who are the main earners in their family. Rebecca Meisenbach at the University of Missouri in Columbia interviewed fifteen women. She found they all valued their independence and many enjoyed having the power of control, though not all wanted it.
But they also felt pressure, worry and guilt. Partly that was because of cultural expectations that working women will still take care of the children. Also, men who are not the main earners may feel threatened.
The job market continues to suffer the effects of last year’s financial crash. Now, a judgment has been reached in the first case involving charges of criminal wrongdoing on Wall Street.
Last week, the government lost its case against two managers at Bear Stearns, the first investment bank to fail last year. A jury found Ralph Cioffi and Matthew Tannin not guilty of lying to investors.
The hedge funds they supervised lost their value in two thousand seven. But jurors said there was no clear evidence that they meant to mislead investors.
The Justice Department continues to investigate other companies.
小題1:Why is the unemployment rate for men higher.
A.Because there are more men workers in industries.
B.Because many industries mainly employing men now don’t need so many workers.
C.More and more women take the place of men.
D.Because health care and temporary employment services don’t employ men.
小題2:It can be inferred from the passage that __________.
A.women haven’t got complete equality as men
B.only by becoming the main earners in their family can women gain a high position
C.a(chǎn)ll women now value independence and the power of control
D.taking care of children is now shared by men and women
小題3:Which of the following is TRUE?
A.Men hate that women earn more money.
B.It is commonly believed that women should take care of children.
C.The job market has recovered from the effect of the financial crisis.
D.Now women working full time earn more than men.
小題4: Why does the government accuse two managers?
A.They contributed to the financial crash.B.They led a corrupt life.
C.They lied to investors.D.A jury found them misleading investors.

It is football time again.Currently, the qualifying rounds are being played to decide which countries will send teams to the next World Cup.Some Soccer is becoming more and more popular on a worldwide scale and these qualifying legs are causing much excitement.
The game is popular at club level as well.Many fans go every week to support their teams, whether the event is a home or away one, hoping to get a result.They all hope an attacking game, with a lot of goals being scored.Obviously, they do not want to see a boring, defensive match where the players are aimlessly passing the ball to each other.
Sadly, not all the action always takes place on the ground.All too frequently, there is action in the stands, too.Football supporters, most of whom declare their loyalty , by wearing their team colors, in the form of shirts, are not known for their quiet behavior.They are often very noisy, shouting noisy encouragement to their team and singing deafening songs.
There is much rivalry between supporters.Mostly, this is good-natured, but trouble can easily arise.Fans get angry if they feel that a referee has made a wrong decision, perhaps giving one of their team a red or yellow card unfairly, or perhaps failing to notice a foul committed by a member of the other team.
When trouble breaks out in a football crowd, it can be difficult to control.Stadium officials often seat the opposing fans in separate parts of the ground as a precaution against fighting. However, preventing trouble is more difficult outside the ground.In the worst cases, riot (暴亂)police have to be called in.
Unfortunately, there are some fans who enjoy this violent aspect of football.These football hooligans (流氓) really enjoy a running battle with the police, and call up other people to throw stones and bottles at them.They regard football not only as a sport, but as an excuse for trouble makings.Inevitably, their behavior spoils the reputation of the game.
小題1:The qualifying rounds are played to ______.
A.make the game more excitingB.a(chǎn)ttract soccer fans at club level
C.raise funds for the organizationD.select the teams for the next rounds

Not too long ago, a Chicago brewery (釀造廠) introduced a new beer that was supposed to be the least fattening(making people fat) on the market. It was lighter, so they called it LITE. Only two months after the new beer had been on sale, however, strange new ads appeared in the Chicago newspapers. They read ’LITE Tastes Soapy’. The public, of course, was confused. Who wanted a beer that tasted like soap(肥皂), even if it was non-fattening?   
The new ads weren’t talking about LITE beer, however. They were for a product of the LITE Soap Company. The president of the LITE Soap Company, Mrs Ruth Ascott, was very upset with the brewery for taking the name of her high-powered detergent (洗滌劑) and using it as the name of a new beer. LITE Soap had had the same name for 53 years. She wrote to the brewery, insisting that they should not use the word LITE in their beer ads. The brewery replied that they could—and would—because beer and soap were so different. They planned to ignore the ’LITE Tastes Soapy’ ads, since the public knew which LITE was which.
Mrs Ascott then wanted to plan a new campaign. The ads would read ’LITE Is Wonderful for Washing Clothes’.
小題1:It is clear that _____.
A. the Chicago brewery was sure the soap company would add to its fame
В. the LITE Soap Company is happy to know the name of the beer
С. the ad ’LITE Tastes Soapy’ did harm to LITE the beer
D. the brewery was not surprised at all to see the ad ’LITE Tastes Soapy’
小題2:It seems that_____.
A.  the new beer may lose weight         В.  the brewery was right
С.  making ads is not difficult           D.  most beer makes us fat
小題3:When the ad ’LITE Tastes Soapy’ comes out, _____.
A. the beer sold well on the market     
В. it confused some consumers of the beer
С. people thought the beer was the least fattening
D. people began to like the product from LITE Soap Company
小題4:We may conclude that_____.
A. neither of the two products sells well
В. both the two companies get on very well
С. the brewery did wrong to the LITE Soap Company
D. it was wrong of the soap company to have LITE as her own name
小題5:When the public read the ad in the last paragraph, they _____.
A. might wash their clothes with the beer       В. are likely to stop to buy the beer
С. might be more confused than ever before     D. may find out which LITE was which

If you’re planning on traveling, there are a few simple rules about how to make life easier both before and after your journey.
First of all, always check and double-check departure (起程) time. It is amazing how few people really do this carefully. Once I arrived at the airport a few minutes after ten. My secretary had got the ticket for me and I thought she had said that the plane left at 10:50. When I arrived at the airport, the clerk at the departure desk told me that my flight was closed. Therefore, I had to wait three hours for the next one and missed an important meeting.
The second rule is to remember that even in this age of credit cards, it is still important to have at least a little of the local currency(貨幣) with you when you arrive in a country. This can be necessary if you are flying to a place few tourists normally visit. A few years ago I was sent to Tulsa, Oklahoma. I flew there from London via(經(jīng)由)Dallas, with very little time to change planes in between. I arrived there at midnight and the bank at the airport was closed. The only way to get to my hotel was by taxi and because I had no dollars, I offered to pay in pounds instead.
“Listen! I only take real money!” the driver said angrily. Luckily I was able to borrow a few dollars from a clerk at the hotel, but it was embarrassing (令人難堪的).
The third and last rule is to find out as much as you can about the weather at your destination before you leave. I feel sorry for some of my workmates who travel in heavy suit and raincoats in May, when it is still fairly cool in London or Manchester, to places like Athens, Rome or Madrid, where it is already beginning to get quite warm during the day.
小題1: According to the passage, it’s obvious that______
A.The author learns some rules of traveling from his own experience.
B.The author doesn’t plan his trips or journeys carefully.
C.Englishmen like to wear heavy suits wherever they travel
D.The America taxi driver never travels to England.
小題2:What should you make sure first before setting off?
A.When you will leave.B.Where you will go.
C.How you will travelD.Whom you will go with.
小題3:According to the passage, the driver was angry because_______
A.the author gave him false money
B.the author did not give him the local currency
C.the author did not give him money
D.the author had no enough change
小題4:Which of the following is TRUE according to the passage?
A.The author tells people to choose warm places as their travel destinations.
B.You don’t have to take credit cards when traveling.
C.You should know more about the weather of the place you’ll visit.
D.You should take enough change when you travel to other countries.
小題5:What is the main idea of the passage?
A.A few simple rules about how to make life easier both before and after your journey.
B.Always check and double-check departure time.
C.It is important to have the local currency with you when you arrive in a country.
D.To find out as much as you can about the weather at your destination before you leave.
