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. 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 7 |
B. 18 |
C. 13 |
D. 384 |

| B. The 18 targets were chosen by chance. |
| C. About 98.4% of the mails didn’t reach their goal because some people were too busy or they mistook the message for junk mail. |

What does the word “estimate” mean in the passage?
| A. make sure |
B. suppose |

| 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. |

She finished her high school education at the College of Sévigné in Paris.
Irene entered the University of Paris in 1914 to prepare for a degree in mathematics and physics. When World War I began, Irene went to help her mother, who was using X-ray facilities (设备) to help save the lives of wounded soldiers.

Sicily, an island of Italy, is home to beautiful beaches, outstanding food, and a bit of Italian history on every corner. It’s located just southwest of the Italian mainland and it’s the largest Mediterranean island. Controlled by many armies over the centuries, it became the site of Roman and Greek colonies(殖民地). Those cultures remain to this day.
As part of the Year of Italy in China, an exhibition of Sicilian culture is being held at the National Museum of China from April 29 to June 27. Although they have a rich culture and history, Sicilian people lead a simple life. Living on land with fertile (肥沃的) soil, most of them work in agriculture, fishing and of course tourism.
In Sicily, most stores and businesses are closed from one to four in the afternoon. Streets become crowded around five as people start to go out and engage in a variety of activities. They may take a walk to the shops, enjoy a pastry (糕点)or just meet up with friends.
Food is one of the great pleasures of Sicilian people. There is an old Sicilian saying: “With a contented stomach, your heart is forgiving. With an empty stomach you forgive nothing.”
People will go miles out their way to eat fresh seafood, such as tuna(金枪鱼), swordfish(箭鱼) and sardines(沙丁鱼).
Pasta (意大利面)is the main food. Each region has its seasonal pasta dishes, and every family cook their own specialty. Bread is common too.

Today we'll talk about reading．When we read a text，our eyes move across a page in short，quick movements．We recognize words usually when our eyes still fixate(停留，凝视)．Each time they fixate，we see a group of words．This is known as the recognition span or the visual span．The length of time for which the eyes stop varies from person to person．It also varies within any person according to his purpose in reading and his familiarity with the text．In addition，it can be affected by such factors as lighting and tiredness.
Unfortunately，in the past，many reading improvement courses have concentrated too much on how our eyes move across the page．As a result of this misleading emphasis on the purely visual aspects of reading，many exercises have been designed to train the eyes to see more words at one fixation．For example，in some exercises，words are flashed on to a screen for a tenth of a second．One of the exercises has required students to fix their eyes on some central point，taking in the words on either side．Such word patterns are often formed in the shape of pyramids，so the reader takes in more and more words at each successive（连续的）fixation．All these exercises are very clever，but it's one thing to improve a person's ability to see words and quite another thing to improve his ability to read a text efficiently.Reading requires the ability to understand the relationship between words．Consequently，for these reasons，many experts have now begun to question the usefulness of eye training，especially since any approach which trains a person to read isolated(孤立的)words and phrases would seem unlikely to help him in reading a continuous text．The time of the recognition span can be affected by the following factors except _______.
| A．1ighting and tiredness |
| B．one's purpose in reading |
| C．the length of a group of words |
| D．one's familiarity with the text |
What does the author mean by the underlined sentence in the second paragraph?
| A．The ability to see words is not needed for an efficient reading． |
| B．The reading exercises mentioned are of little help to an efficient reading. |
| C．The reading exercises mentioned can help improve reading. |
| D．The reading exercises mentioned have done a great job so far. |
The author may believe that reading ______________.
| A．demands a deeply-participating mind |
| B．requires a reader to see words more quickly |
| C．requires a reader to take in more words at each fixation |
| D．demands more eyes than mind |
The tune of the author in writing this text is _________________．
| A．supportive | B．neutral |
| C．critical | D．optimistic |
Over 500 dogs being delivered to a butcher house were saved by a Chinese animal protection organization.
The incident then triggered debate among Chinese netizens about the necessity of pouring so much money and efforts into saving dogs.
On Friday, a truck loaded with over 500 dogs were stopped by volunteers from animal protection organization on Jingha Expressway Beijing section.
Beijing Times reported these dogs were being delivered to slaughter houses in the city of Changchun, northeast Jilin Province and would be eventually served on dinner tables.
After negotiations with the truck driver, pet service provider Leepet Holding Corp.and a philanthropic foundation, Shang shan Foundation purchased these dogs, each paying 50,000 yuan.Dogs were then delivered to the headquarter of China Small Animal Protection Association (CSAPA), being taken care of and waiting for adoption.
After the “dog saving mission” was reported, Chinese net users debate over whether saving dogs worth so much efforts and money while there are still many poor and needy people in China lacking assistance.
Some net users argue the “dog saving mission” is placing overt attention to animals while lots of needy people are still left unattended.
A microblogger “Xiaowulaitajie” said on China's twitter like website, weibo.com, “Dogs are saved, adopted and they attracted media spotlight. We'd better spend such money and take such efforts in helping the needy people.”
Another microblogger, Liluping, said “We poured such huge sum of money into saving dogs.I would rather the money be spent on disaster relief.”
Some applaud volunteers'actions and show eagerness of offering their helping hands to those saved dogs.
Still many disapprove those “saving dogs” critics, but they argue that such act nonetheless promotes social progress.
A microblogger named “broken bridge” said, saving dogs does not run counter to taking care of people.Such enthusiasm in public affairs will help raise social awareness in helping the needy.
I think people and animals are created equal.Attention should be paid to people as well as animals.

Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?
UBC Professor Simard explains how trees are much more complex than most of us ever imagined.Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was.In fact, the opposite is true: trees survive through their co-operation and support, passing around necessary nutrition “depending on who needs it”.
Nitrogen（氮） and carbon are shared through miles of underground fungi（真菌） networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons（神经元）in our brains, and when one tree is destroyed, it affects all.
Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend.She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow.When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the entire forest.
“We didn't take any notice of it.” Simard says sadly.“Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.What would be the best title for the passage?
| A．Old Trees Communicate Like Humans |
| B．Young Trees Are In Need Of Protection |
| C．Trees Contribute To Our Society |
| D．Trees Are More Complex Than You Think |
In Simard's opinion, trees _______
| A．compete for survival | B．protect their own wealth |
| C．depend on each other | D．provide support for dying trees |
We can learn from the passage that.
| A．“mother trees” are usually of no use to other trees. |
| B．Charles Darwin had the same thought as Simard. |
| C．if “mother trees” are cut down, the survival for the entire forest will be affected. |
| D．people know much about the complex “tree societies”. |
The underlined word “it” in the last paragraph refers to .
| A．how “tree societies” work |
| B．how trees grow old |
| C．how forestry industry develops |
| D．how young trees survive |
