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 chosen people. Each participant started by sending one e-mail to someone they knew. Recipients could then forward the e-mail once to someone they knew, and so on.
Targets, 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 estimated 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 whereas 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?

There was a time when the owners of shops and businesses in Chicago had to pay large sums of money to gangsters(匪徒)in return for “protection”. If the money was not paid immediately, the gangsters would quickly put a man out of business by destroying his shop. Getting “protection money” is not a modern means. As long ago as the fourteenth century, an Englishman, Sir John Hawkwood, made the remarkable discovery that people would rather pay large sums of money than have their life work destroyed by gangsters.
Then Sir John Hawkwood arrived in Italy with a group of soldiers and settled near Florence. He soon made a name for himself and came to be known to the Italians as Giovanni Acuto. Whenever the Italian city-states were at war with each other, Hawkwood used to hire his soldiers to those who were willing to pay the high price he demanded.  In times of peace, when business was bad, Hawkwood and his men would march into a city-state and, after burning down a few farms, would offer to go away if protection money was paid to them. Hawkwood made large sums of money with this method. In spite of this, the Italians regarded him as a sort of hero .When he died at eighty, the Florentines gave him a state funeral and had his picture painted, which was in memory of “this bravest man”.
【小題1】What protection did Chicago gangsters give to those who paid them?

To Friend or Not To Friend
We all love our parents and turn to them when we’re in need, but would you like them to hear the conversations you have with your friends on the school playground or lunch queue? Social networking sites have become extensions of the school hallways, so would you add your parents as “friends” and allow them to view your online activities and conversations with friends?
In the past the generation gap included a technology gap, where children were up to date with latest technology and parents were left behind, content to continue their day to day lives as they always had because they had no need to know more about technology. However, more and more parents are beginning to realize just how important social networks are in their lives. This realization has given many parents the motivation to education themselves about social networking sites.
These days many people are attracted to social networking sites because they can choose who they have around them; there’s also a certain amount of control over privacy that we don’t get in real life. Sometimes we feel that privacy is violated when we must accept a “friend” request from a parent or family member.
It’s a difficult choice whether or not to allow a parent to become a part of our online lives. On the one hand we don’t want to “reject” their request because that might hurt their feelings or make them feel you have something to hide. On the other hand if you do accept, then you could have a sense of being watched and no longer feel free to comment or communicate the way you did before.
A recent survey suggested that parents shouldn’t take it personally if their child ignores their request, “When a teen ignores a parent’s friend request, it doesn’t necessarily mean that they are hiding something, but it could mean that this is one part of their life where they want to be independent.”
Perhaps talking with parents and giving explanations would help soften the blow if you do choose not to add them to your friends list.
【小題1】From Paragraph 2, we learn that _______.

Water runs downhill from mountaintops to streams to rivers to oceans. But downhill isn’t the only way that water moves .A new study measures how water travels from country to country for human consumption. This flow isn’t the type we usually think about .These scientists looked at the water used to grow and make the products which get shipped from nation to nation as imports or exports. They call this a flow of“virtual water（虛擬水）”.
We typically think about water as the liquid that flows from a tap. However,92％of the water used by people goes into growing crops，according to water researcher Arjen Hoekstra. He recently studied the hidden travels of virtual water used in products made from things like crops and meats .These products are shipped around the world.
For example．consider a sugary soft drink. Hoekstra estimated that to produce one half-liter of the drink requires between 170 and 310litersofthewater—about 95％—is used to grow and process the ingredients(原料).Another 4％goes into the packaging and labeling. In Hoekstra’s calculation, when one country produces a half-liter of soda and sells it abroad，it exports as much virtual water as would fill a large refrigerator．
According to Hoekstra’s new report，dry countries like Israel and Kuwait，both in the Middle East, get the majority of their virtual water from other countries，through imported products. More surprisingly, some wetter countries，like the Netherlands and the United Kingdom, also get the majority of their virtual water from other places. That means that most of the water used to grow or produce the products and food consumed in those countries came from other countries.   
In the United States most of the virtual water used comes from American sources .In China even less of the water associated with its products
【小題1】What is the best title for the passage?

Everywhere I look outside my home I see people busy on their high-tech devices, while driving, walking, shopping, even sitting in toilets. When connected electronically, they are away from physical reality.
People have been influenced to become technology addicted. One survey reported that “addicted” was the word most commonly used by people to describe their relationship to iPad and similar devices. One study found that people had a harder time resisting the allure of social media than they did for sleep, cigarettes and alcohol.
The main goal of technology companies is to get people to spend more money and time on their products, not to actually improve our quality of life. They have successfully created a cultural disease. Consumers willingly give up their freedom, money and time to catch up on the latest information, to keep pace with their peers or to appear modern.
I see people trapped in a pathological（病態(tài)的）relationship with time-sucking technology, where they serve technology more than technology serves them. I call this technology servitude. I am referring to a loss of personal freedom and independence because of uncontrolled consumption of many kinds of devices that eat up time and money. 
What is a healthy use of technology devices? That is the vital question. Who is really in charge of my life? That is what people need to ask themselves if we are to have any chance of breaking up false beliefs about their use of technology. When we can live happily without using so much technology for a day or a week, then we can regain control and personal freedom, become the master of technology and discover what there is to enjoy in life free of technology. Mae West is famous for proclaiming the wisdom that “too much of a good thing is wonderful.”  But it’s time to discover that it does not work for technology.
Richard Fernandez, an executive coach at Google acknowledged that “we can be swept away by our technologies.”  To break the grand digital connection people must consider how life long ago could be fantastic without today’s overused technology.
【小題1】The underlined word “allure” in Paragraph 2 probably means ______.

   In bringing up children, every parent watches eagerly the child's acquisition (學(xué)會) of each new skill m the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself.
Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are severe (嚴(yán)格的) over time of coming home at night or punctuality for meals. In general, the controls represent the needs of the parents and the values of the community as much as the child's own happiness.
As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality (道德). Also, parents should realize that "example is better than precept". If they are not sincere and do not practice what they preach (說教), their children may grow confused when they grow old enough to think for themselves, and realize they have been to some extent fooled.
A sudden awareness of a marked difference between their parents' principles and their morals can be a dangerous disappointment.
【小題1】Eagerly watching the child’s acquisition of new skills, _________________.

In the past ten years, America’s National Basketball Association (NBA) has grown increasingly dependent on the rest of the world to supply players.
When Michael Jordan and Larry Bird won gold in Barcelona in 1992, the Americans were praised for teaching the world how to play basketball. This season, however, 20 percent of NBA rosters（花名冊） will be filled by non-Americans. NBA commissioner David Stem happily embraces the trend. On a visit to Paris in October, Stern outlined his vision for the future, which is likely to see Europe hosting NBA games by 2010.
The NBA is now planning to take China by storm.
“Our experience in China has been that it is going to be explosive in its growth,” said Stern. The strategy（戰(zhàn)略，策略） in China is television. “We’ve made 14 deals in China with local and national networks on cable and satellite.” The success of Chinese centre Yao Ming has paved the way for the NBA marketing blitz in China. The NBA, which is broadcasted in more than 200 countries in 42 languages, will put that to the test in October 2004 when the Houston Rockets play two pre-season games against the Sacramento Kings in Beijing and Shanghai. The NBA knows that it needs a global market to compensate for tough times on home soil.
“It doesn’t matter where the players come from, all the NBA teams now know that they have to scout（尋找，覓得） internationally,” said Terry Lyons, the NBA’s vice-president of international public relations. “It has increased the level of competition here.” As Frenchman Tony Parker and Argentine Emanuel Ginobili showed in winning championship rings with the San Antonio Spurs last season, many people can earn the respect of their American peers. Others, such as the Houston Rockets’ Chinese centre Yao Ming — number one draft pick in 2002 — and the Detroit Pistons’ 18-year-old Serb Darko Milicic — number two overall in this year’s draft — are icons（偶像）in-waiting. It is the ultimate（最后的，根本的） revolution — the rest of the world teaching the US how to play basketball.
【小題1】According to the report,                 .

There’s been a lot of talk about white-and-blue collar（衣領(lǐng)） workers, and you may have even heard of gold collar workers, but lately a new color of collar is making its way into China’s urban vernacular(土話)—green. Green collars say no when work is life and life is work. They choose to get out of the fast lane(車道), and explore new ways of living “green”.
Living green doesn’t mean someone is working as an environmentalist, biologist or scientist. Instead it is more of a lifestyle choice. A typical green collar is well educated like a white-collar but physically tough like a blue-collar, likely born in the 70s or 80s of the last century and living in one of China’s big cities, with a monthly income well above 5,000 yuan(about US $700).
The life of a green collar may go something like this: Turn off the mobile phone after work, eat only healthy food rich in vitamins, go on hikes every weekend, and like to help the underprivileged.
Green collars even have their own club. In Beijing, the Green Collar Club is for people who share a “be happy, healthy and helpful” spirit. The club often holds charity parties and uses the donations for environmental protection and poverty relief projects in China.
“They are successful in their careers, but do not miss the pleasures in life. They have a lot of money, but do not fall slave to it.” said Zuo Shiguang, one of the founding members of the club.
【小題1】What is the passage mainly about?

His ignorance was as remarkable as his knowledge. Of contemporary literature, philosophy and politics he appeared to know next to nothing. Upon my quoting Thomas Carlyle, he inquired in the naivest way who he might be and what he had done. My surprise reached a climax, however, when I found incidentally that he was ignorant of the Copernican Theory and of the composition of the Solar system.
“You appear to be astonished, ” Holmes said, smiling at my expression. “Now that I do know it I shall do my best to forget it. You see, I consider that a man’s brain originally is like a little empty attic, and you have to stock it with such furniture as you choose: A fool takes in all the lumber of every sort that he comes across, so that the knowledge which might be useful to him gets crowded out, or at best jumbled up with a lot of other things, so that he has difficulty in laying his hand upon it. It is a mistake to think that the little room has elastic walls and can distend to any extent. Depend upon it, there comes a time when for every addition of knowledge you forget something that you know before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.”
“But the Solar System! ” I protested.
“What the deuce is it to me?” he interrupted impatiently.
One morning, I picked up a magazine from the table and attempted to while away the time with it, while my companion munched silently at his toast. One of the articles had a pencil mark at the heading, and I naturally began to run my eye through it.
Its somewhat ambitious title was “The Book of Life, ” and it attempted to show how much an observant man might learn by an accurate and systematic examination of all that came in his way. It struck me as being a remarkable mixture of shrewdness and of absurdity. The reasoning was close and intense, but the deduction appeared to me to be far-fetched and exaggerated. The writer claimed by a momentary expression, a twitch of a muscle or a glance of an eye, to fathom a man’s inmost thought. Deceit, according to him, was impossibility in the case of one trained to observation and analysis. His conclusions were as infallible as so many propositions of Euclid. So startling would his results appear to the uninitiated that until they learned the processes by which he had arrived at them they might well consider him as a necromancer.
“From a drop of water, ”said the writer, “a logician could infer the possibility of an Atlantic. So all life is a great chain, the nature of which is known whenever we are shown a single link of it. Like all other arts, the science of Deduction and Analysis is one which can be acquired by long and patient study, nor is life long enough to allow any mortal to attain the highest possible perfection in it. ”
This smartly written piece of theory I could not accept until a succession of evidences justified it.

In the US, people prefer waiting for a table to sitting with people they don’t know. If you are sitting at a table with people you don’t know, it is impolite to light up a cigarette without asking if it will trouble them.
At American restaurant and coffee shops you are usually served cold water before you order. You may find the bread and butter is free, and if you order coffee, you may get a free refill(再裝滿).
Most cities and towns have no rules about opening and closing time for stores or restaurants, though they usually do make rules for bars. Especially in large cities, stores may be open 24 hours a day.
Serving in restaurant is often large, too large for many people. If you can’t finish your meal but would like to enjoy the food later, ask your waitress or waiter for a “doggie bag”. It may have a picture of a dog on it, but everyone knows you’re taking the food for yourself. Supper and dinner are both words for the evening meal. Some people have “Sunday dinner”. This is an especially big noon meal.
Tips are not usually added to the check. They are not included in the price of the meal, either. A tip of about 15% of the price of a meal is expected and you should leave it on the table when you leave. In some restaurants, a check is brought on a plate and you put your money there. Then the waiter or waitress brings you your change.
