Uthman Affan was a very rich man who was known for his generosity. In fact he was so generous that people still tell stories about him today, more than a thousand years later.

    Uthman lived in Medina. It is a very dry part of the world where there isn't a lot of rainfall. One year, the rain didn't come and there was a drought（干旱）. People were running out of food. Things got so bad that the people had to eat leaves from the trees in order to survive.

    You can imagine how happy the people and the merchants（商人）were when they learned that a group of camels（骆驼）were approaching Medina. Each camel carried a lot of food, and the people looked forward to being able to eat good food again. Knowing that the group belonged to Uthman made the people even happier, for they knew he is well-known for generosity. But it was not welcome news for the merchants in Medina, because Uthman was a very sharp businessman. Although he was fair, Uthman drove a very hard bargain.

    Even so, the merchants immediately went to Uthman. They wanted to buy the food on the camels from him so they could sell it for two or even three times its usual price at that time. So they were ready to pay any price Uthman asked. But Uthman turned them down. The merchants raised their offers again and again, but each time Uthman refused. Finally the merchants made their best offer: five times the value of the food. Guess what? Uthman had made a decision to give away all the food to the starving people of Medina.

    People are less willing to rely on their knowledge and say they know something when they have access (接近) to the Internet, suggesting that our connection to the web is affecting how we think.

    Professor Evan Risko, of the Department of Psychology at the University of Waterloo, led a recent study where the team asked about 100 participants (参与者) a series of general-knowledge questions, such as naming the capital of France. For half of the study, participants had access to the Internet. They had to look up the answer when they responded that they did not know the answer. In the other half of the study, participants did not have access to the Internet.

    The team found that the people who had access to the web were about 5 percent more likely to say that they did not know the answer to the question. Furthermore, in some cases, the people with access to the Internet reported feeling as though they knew less compared to the people without access.

    “With the popularity of the Internet, we are almost frequently connected to large amounts of information. And when that data is within reach, people seem less likely to rely on their own knowledge,” said Professor Risko.

    Studying the results, the researchers thought that access to the Internet might make it less acceptable to say you know something but are incorrect. It is also possible that participants were more likely to say they didn't know an answer when they had access to the web because online searching offers an opportunity to confirm their answer, and the process of finding out the answer is rewarding.

    “Our results suggest that access to the Internet affects the decisions we make about what we know and don't know,” said Risko. “We hope this research helps us understand how easy access to large amounts of information can influence our thinking and behaviour.”

There's a song by the great Jamaican singer Bob Marley called So Much Trouble In The World. Marley understood that part of the reason why there are so many problems in the world is the lack of tolerance between people. The UN understands this too — that's why it made Nov 16th "International Day for Tolerance".

But first of all, what is tolerance? According to French philosopher Voltaire, tolerance "s the consequence of humanity. We are all formed of frailty (脆弱) and error; let us pardon each other's fool — that is the first law of nature."

    Very often, people don't realize that they're intolerant. This is because intolerance has a lot to do with ignorance. For example, the UN's campaign is in part about the treatment of females by males. But often, the behavior of men toward women is intolerant because men don't put themselves in the shoes of women.

    It's worth thinking a little about the words "tolerance" and "intolerance". Are they the best words to describe the evils of which we're speaking here? To agree to be "tolerant" of someone isn't necessarily a very respectful thing. When someone is tolerated, it implies that there's something wrong with them.

    Still, what Voltaire said stands: We humans are not perfect and this weakness is something that we all share. That's the reason we should be tolerant. It's a little like generosity. We can give things to another person, and we can also give our forgiveness.

    Generally speaking, people like those who have a good sense of humor.

    Sometimes a touch of humor might well enable us to win. Consider the case of a young friend of mine, who hit a traffic jam on his way to work shortly after receiving an ultimatum (最后通牒) about being late on the job. Although there was a good reason for Brian's being late—serious illness at home—he decided that this by-now-familiar excuse wouldn't work any longer. His boss was probably already pacing up and down preparing a dismissal speech.

    Yes, the boss was, as Brian entered the office at 9:35. The place was as quiet as a locker room (更衣室): everyone was hard at work. Brian's boss came up to him. Suddenly, Brian forced a smile and stretched out his hand. "How do you do!" he said. "I'm Brian. I'm applying for a job, which, I understand, became available just 35 minutes ago. Doesn't the early bird get the worm?"

    The room exploded in laughter. The boss clamped off a smile and walked back to his office. Brian had saved his job, with the only tool that could win—a laugh.

    Humor is a most effective, yet frequently neglected means of handling the difficult situations in our lives. It can be used for patching up differences, apologizing, saying "no", criticizing, getting the other fellow to do what you want without his losing face. For some jobs, it's the only tool that can succeed. It is a way to discuss subjects so sensitive that serious dialog may start a quarrel. For example, many believe that comedians on television are doing more today for racial and religious tolerance (忍受力) than people in any other forum.

    A day in the life of 18­year­old David Lanster is full of typical teenage stuff: school, baseball practice and homework. And then he starts cooking. "Some nights I'm up until 1: 00 a. m. making pies, or even later if we're cooking beef," said the student at Ransom Everglades High School in Florida, US.

    For the past year, Lanster and Kelly Moran, his classmate, have been hosting fancy dinner parties at Lanster's parents' home. Their meals have 17 courses and are all made by themselves. Their guests used to give them gifts to thank them until the pair decided to do something nice for charity. "We got some really great Miami Heat tickets, a nice watch, and many kitchen gadgets (小器具)," Lanster said. "But we wanted to make this something positive for people other than us."

    Lanster and Moran focus on Common Threads, a charity that aims to teach kids in poor communities to cook and make healthy eating choices. The young cooks ask their guests to give however much they want as payment for their meals. It all goes to Common Threads because Lanster's parents cover their food costs. After their last 12­person event, Lanster and Moran gave $1,600 to the charity.

    Now, they're taking their show out of the kitchen and on the road. They have started to organize private dinner parties with a similar model: the host pays for the ingredients, and the guests make a donation to a charity of their choice.

    Without formal training, Lanster said he had been interested in cooking since he helped his mom in the kitchen when he was very young. He learned how to cook by reading cookbooks and watching TV programs. Outside the kitchen, the two are busy preparing their college applications. Neither of them is sure what they will do in the future, but they've promised their parents that they will leave professional cooking alone until they finish school.

    Twenty years ago, most experts believed that differences in how boys and girls behaved were mainly due to differences in how they were treated by their parents, teachers, and friends. It's hard to cling to that belief today. Recent research has shown that there are biological differences between boys and girls. Understanding these differences is important in raising and educating children.

    For example, girls are born with more sensitive hearing than boys, and the difference increases as kids grow up. So when a grown man speaks to a girl in what he thinks is a normal voice, she may hear it as yelling. Conversely (反过来), boys who appear to be inattentive in class may just be sitting too far away too hear the teacher.

    Likewise, girls are better in their expression of feelings. Studies reveal that negative emotions are seated in an area of the brain called the amygdala. Girls develop all early connection between this area and the cerebral cortex (大脑皮层), enabling them to talk about their feelings. In boys these links develop later. So if you ask a troubled adolescent boy to tell you what his feelings are, he often cannot say much.

    Dr. Sax, an advocate of single-sex education, points out that keeping boys and girls separate in the classroom has yielded striking educational, social, and interpersonal benefits. Therefore, parents and teachers should try to recognize, understand, and make use of the biological differences that make a girl a girl, and a boy a boy.
