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 |

| 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. |

Some 80 percent of graduate students in East China’s Zhejiang Province said in a survey they will give up trying to find jobs in Beijing，Shanghai and Guangzhou，first-tier cities in China that have been considered dream places for many，because of the untouchable home prices and high living costs．
The Yangtse Evening Post conducted the survey among 50 job seekers who were attending Sunday’s job fair in Jiangsu for graduate students．The survey showed graduates are becoming more realistic in their job search despite the job market becoming better．
The fair attracted more than 10，000 graduate students with 7，382 positions．
“The pressure of buying a house in Beijing is unbelievable，”said Wang Jian from Nanjiing Normal University，who acknowledged he had thought about finding a job in Beijing，Shanghai or Guangzhou，but in the face of huge pressures，he has no choice but to be “realistic”．
People can have a very comfortable life in Nanjing with a monthly salary of between 3，000 yuan($450)and 4，000 yuan，but in Shanghai，5，000 yuan a month can only help you survive and buying a house will remain a dream．
A student from Nanjing University of Science and Technology said he just turned down an offer from a Shanghai company of 7,000 yuan a month because“living costs in Shanghai are too high．”
An unnamed male student from Nanjing University said he will try first-tier cities only if he can get a high salary．“I would go to Beijing only if I can earn 200，000 yuan a year，”he said．
“Beijing，Shanghai and Guangzhou once had the advantages that other cities don’t have，but the high housing prices and living costs make young people barely able to breathe，”said Ren Leiming from the job service center of Jiangsu’s colleges and universities．
“First-tier cities have plenty of talents that make it hard for people to be outstanding，and if you go work in smaller cities you can become a dominant player at your position much more easily，”said Ren．The majority of graduate students will give up trying to find jobs in the first-tier cities because .
| A．it is not easy to find jobs there． |

Americans love to talk and generally it is OK to talk even to strangers about nearly any subject at any time as long as you are polite．However there are some subjects，like racism，American foreign policy，gun ownership，and religion that are best discussed among friends．
In America，it is OK to approach a stranger and start up a conversation with him as long as the subject is not too abstract．In America，it is not considered inappropriate to talk to people you don’t know．Talking to a stranger about the weather or the quality of nearby restaurants，or the prices in a grocery store is all perfectly fine．Even complimenting someone on the car they drive or asking them where they bought their clothes are all appropriate topics of conversation with complete strangers．
Generally，Americans prefer that people say what they think and they respect frankness．Usually when it comes to personal matters，it’s best to accentuate(强调)the positive：don’t tell someone that their children are ugly or that their cooking is terrible．However；it’s OK to tell someone that they are wrong as long as you do so politely and with respect．Americans generally believe that you show someone respect by telling them the truth．Don’t be afraid to be honest with Americans，but be appropriate．

Science can’t explain the power of pets，but many studies have shown that the company of pets can help lower blood pressure(血压) and raise chances of recovering from a heart attack，reduce loneliness and spread all-round good cheer．
Any owner will tell you how much joy a pet brings．For some．an animal provides more comfort than a husband／wife．A 2002 study by Karen Allen of the State University of New York measured stress(紧张)1evels and blood pressure in people－half of them pet owners－while they performed 5 minutes of mental arithmetic(算术)or held a hand in ice water．Subjects completed the tasks alone，with a husband／wife，a close friend or with a pet．People with pets did it best．Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates．With pets in the room，people also made fewer math mistakes than when doing in front of other companions．It seems people feel more relaxed(放松)around pets，says Allen，who thinks it may be because pets don’t judge．
A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits．Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs；a separate group of 56 people without pets were put on a diet program．On average，people lost about 11 pounds，or 5％ of their body weight．Their dogs did even better，losing an average of 12 pounds，more than 15％of their body weight．Dog owners didn’t lose any more weight than those without dogs but，say researchers，got more exercise overall－mostly with their dogs--and found it worth doing．What does the text mainly discuss?

How Can Excess Weight Hurt Your Health?
It's hard to feel good when your body has too much weight to carry. Being overweight or obese can make it harder to breathe and sleep. It can make a person feel tired and cause aches or pains. A weight problem also can make you embarrassed, sad, or even angry.
___________________________?
One of the best ways to stay at a healthy weight is to be active. You can join a sports team. Or, if you don't like team sports, try swimming, tennis, martial arts, or just being active in your own backyard. Jumping rope, dancing, and running around will get your heart pumping.
Getting some extra exercise can be as easy as taking the stairs instead of the elevator or walking instead of having your parents drive you. Being active also means watching less TV and playing fewer video games.
___________ is another part of staying fit. Aim to eat a variety of foods and get five servings of fruits and vegetables a day. Choose water and low-fat milk over soda and other sugary drinks. When it comes to high-calorie and high-fat foods, eat them only once in a while and, when you do, have smaller portions.
What Should You Do?
Talking to a parent is the best first step if you are concerned about your weight. Your mom or dad can make a doctor's appointment for you. The doctor may suggest ways of changing your eating and exercise habits.
In general, kids don't need to diet. But a kid who is very overweight may need some expert help from a dietitian or a doctor who specializes in weight management. Together, along with your family, you'll be able to come up with a safe and healthy plan that should include eating nutritious foods and exercising regularly.What is the best title of the second part?
