My decision to travel around China lay merely with my curiosity about the place. Before coming here, China seemed alien to me —-a place that expected to be hugely dissimilar from my own British culture.

After travelling from Beijing up to Xi'an, I wanted to challenge myself by choosing a smaller town—-Xiahe in Gansu Province. I arrived in Lanzhou at around 5 am, but there were no buses to Xiahe. I managed to spot a policeman and attempted to explain my destination to him in simple English, praying that he would understand. I wasn't sure that he did but I just followed him anyway as I had no choice. He took me on a bus and I didn't know where I was going. Luckily, I met a student who explained to me in English that the policeman was taking me to another bus station where I could take a bus to Xiahe. During this conversation a third man said he was also a policeman and would help me buy tickets. But as he was not in uniform, I was a little doubtful. The uniformed policeman told me it was OK to go with the third man, so I got off the bus with the so-called policeman who at this point, disappeared and I was left in the middle of nowhere. I stood panicking. Around one minute later a police car came and stopped right by me. It was the un-uniformed policeman. I got into the car and he dropped me directly at the bus station, and helped me buy the ticket.

    This is one of many experiences that I have had in China. I realized that however different this culture was, there was one thing that would always stand out—kindness. In the west we seem to lack the foundation of trust, yet in China it seems that there will always be someone to answer your questions and lead you the right way.

    Recently, we've been talking about how we need better teachers. There's no doubt that great teacher can help in a student's learning but here's what some new studies are also showing: We need better parents.

    Every three years, the organization called O.E.C.D. organizes exams as part of the Program for International Student Assessment(评估), or PISA, which tests 15-year-olds on their abilities to deal with real problems. America's 15-year-olds have not done as well as students in Singapore, Finland and Shanghai in the PISA exams.

    To better understand the reasons, the PISA team, starting with four countries in 2006, and then adding 14 more in 2009, went to the parents of 5,000 students. They interviewed them about how they raised their kids and then compared it with the test results for each of those years. Two weeks ago, the PISA team published the main finding of its study.

    Fifteen-year-olds whose parents often read books with them during their first year of primary school get much higher scores in PISA 2009 than students whose parents don't often read with them or not at all. Parents' concern for their children is strongly connected with better results in PISA.

    According to Schleicher, the leader of the team, just asking your children how their school    day was and showing great interest in their learning can help a lot. It is something every parent can do, no matter what their education level is.

    The study found that getting parents concerned about their children's learning at home is more powerful than parents attending parent-teacher meetings, volunteering in classrooms,   taking part in money-raising, and showing up at back-to-back nights.

    To be sure, nothing can replace a good teacher. But let's stop putting the whole duty on teachers. We also need better parents. Better parents can make teaching more beneficial.

    Reading may be fundamental, but how the brain gives meaning to letters on a page has been a mystery. Two new studies fill in some details on how the brains of efficient readers handle words. One of the studies, published in the April 30 Neuron, suggests that a visual-processing area of the brain recognizes common words as whole units. Another study, published online April 27 in PLOSONE, makes it known that the brain operates two fast parallel systems for reading, linking visual recognition of words to speech.

    Maximilian Riesenhuber, a neuroscientist at Georgetown University in Washington, D. C. , wanted to know whether the brain reads words letter by letter or recognizes words as whole objects. He and his colleagues showed sets of real words or nonsense(无意义的词语)words to volunteers undergoing FMRI scans. The words differed in only one letter, such as “farm” and “form” or “soat” and “poat”, or were completely different, such as “farm” and “coat”or “poat” and “hime”.The researchers were particularly interested in what happens in the visual word form area, or VWFA, an area on the left side of the brain just behind the ear that is involved in recognizing words.

    Riesenhuber and his colleagues found that neurons(神经元)in the VWFA respond strongly to changes in real words. Changing “farm” to “form”, for example, produced as great a change in activity as changing “farm” to“coat”, the team reports in Neuron. The area responded slowly to single-letter changes in made-up words.

    The data suggests that readers grasp real words as whole objects, rather than focusing on letters or letter combinations. And as a reader's exposure to a word increases, the brain comes to recognize the shape of the word. “Meaning is passed on after recognition in the brain”, Riesenhuber says.

    The researchers don't yet know how longer and less familiar words are recognized, or if the brain can be trained to recognize nonsense words as a unit.

    Nowadays women appear to have a positive image of themselves as safer drivers than men.

    In a survey done for insurer MetLife, 51% of women said they drive more safely. The evidence is on their side: Men are 3.4 times more likely than women to get a ticket for careless driving and 3.1 times as likely to be punished for drunk driving. "Women are on average less aggressive and more law abiding (守法的) drivers, which leads to fewer accidents," the report says. However, not all male drivers share the same opinion. Of the men surveyed by MetLife, 39% claimed male drivers were safer. The findings did back them up on one point: automotive knowledge. The report showed that more men are familiar with current safety equipment such as electronic stability control, which helps prevent rollover accidents.

    Auto safety unavoidably matters to money. Insurance companies focus on what classes of drivers have the lowest dollar amounts of claims, and for now, that mainly includes women. In general, women pay about 9% less for auto insurance than men. A study by the website Insweb also showed that auto insurance rates are lower for women in most states. Among individual states, women get the greatest advantage in Wyoming (where they pay 20% less), South Dakota and Washington, D. C. where their insurance costs are 16% lower.

    "More than 11, 900 male drivers died in U. S. traffic accidents in 2009, compared with just under 4, 900 women drivers," according to the study. "Based on miles traveled, men died at a rate of 2.5 deaths per 100 million miles traveled, VS 1.7 deaths for women."

In the 1990s, a psychologist named Martin Seligman led the positive psychology movement, which placed the study of human happiness squarely at the center of psychology research and theory.

Since then, thousands of studies and hundreds of books have been published with the goal of increasing well-being and helping people lead more satisfying lives. But for over 40 years, self-reported measures of happiness have stayed stagnant (停滞的). Such efforts to improve happiness have been an ineffective attempt to swim against the tide, as we may actually be programmed to be dissatisfied most of the time. Why aren't we happier?

Part of the problem is that happiness isn't just one thing. Jennifer Hecht, a philosopher who studies the history of happiness, proposes that we all experience different types of happiness, which are not necessarily complementary Some types of happiness may even conflict with one another. In other words, having too much of one type of happiness may weaken our ability to have enough of the others. For example, a satisfying life is built on a successful career and a good marriage. It takes a lot of work and often requires cutting back on many of life's pleasures. That means we can't spend one pleasant lazy day after another in the company of good friends.

This difficult situation becomes more confused by the way our brains process the experience of happiness. A lot of evidence shows that most of the people possess something called the optimistic bias. They tend to think that their future will be better than the present.

Cognitive psychologists have also identified something called the Pollyanna Principle. It means that people process, rehearse and remember pleasant information more than unpleasant information. Why the good old days seem so good is because we focus on the pleasant stuff and tend to forget the unpleasantness. And if our past is great and our future can be even better, then we can work our way out of the unpleasant present.

Dissatisfaction with the present and dreams of the future are what keep us motivated. In fact, endless happiness would completely destroy our will. Among our earliest ancestors, those who were perfectly content may have been left in the dust.

Recognizing that happiness exists may help us appreciate it more when it arrives. Furthermore, understanding that it's impossible to have happiness in all aspects of life can help us enjoy the happiness that has touched us. Recognizing that no one "has it all" can cut down on the one thing that psychologists know prevents happiness: envy.

A recent story on TikTok showed how two neighbors found companionship (陪伴) and a new spirit in life during COVID-19, thanks to a shared love of the piano.

The heartbreaking story started when Giorgio Lo Porto heard his neighbor playing the piano through their dividing wall. Lo Porto is an Italian living in London. He reached out to his neighbor and left a note, saying if he or she could play My Heart Will Go On. The mystery neighbor agreed, suggesting they play together. Over time the music between two complete strangers became a regular weekend engagement(约会).

A week later, the pair finally met and "it was better than expected," shared Lo Porto. The mystery pianist happened to be a78-year-old Polish man named Emil. "He lost his wife in December due to COVID-19 and all he has been left is the piano. And he plays at 2 p.m. every weekend because his wife loved it," shared Lo Porto.

While Emil didn't want to appear on any of the videos, he did share his thankfulness to Lo Porto for keeping him motivated during a most emotional and lonely time.When the pair offered each other company, Emil also inspired Lo Porto to continue writing his own song. And Emil reported being happier after playing music with Lo Porto and was thankful to those who watched their performance.

The bittersweet story shows the unbelievable influence two complete strangers can have on each other. Emil moved out at the end of February. Lo Porto wrote, "Dear Emil, you changed my life. You gave me back my passion (激情)，and we shared that with the world. You'll be in my heart. I'll keep playing, thinking of how powerful music can be. You said I was your light, but you've been mine too. Bye, Emil."
