About 30 years ago, I left Cuba for the United States with my son. After getting settled finally in Brunswick, New Jersey, I enrolled(注册) my son in kindergarten. Several weeks later, my son's teacher asked me to meet him at his office.

In the teacher's office, and exchange of greetings was followed by his questions: “Is your son mentally retarded(弱智的)？Does he suffer from any kind of mental disability?”

Was he talking about my wonderful Scola? NO, no, it can't be. What a helpless, lonely moment! I told him that Scola was a quiet, sweet little boy, instead. I asked him why he was asking me all these questions.

My son could not follow the teacher's directions, he told me, and thus, Scola was disrupting the class, Didn't he know my son did not speak English yet?

He was angry; “Why hasn't your son been taught to speak English? Don't you speak English at home?”

No, I didn't speak English at home, I replied. I was sure my son would learn English in a couple of months, and I didn't want him to forget his native language. Well, wrong answer! What kind of person would not speak in English to her son at home and at all time? “Are you one of those people who come to this country to save dollars and send them back to their country, never wanting to be a part of this society?”

    Needless to say, I tried to tell him I was not one of “those people.” Then he told me the meeting was over, and I left.

    As I had expected, my son learned to speak English fluently before the school year was over. He went on to graduate from college and got a job, earning close to six figures. He travels widely and leads a well-adjusted, contented life. And he has benefited from being bilingual(双语的)。

    Speaking more than one language allows people to communicate with others; it teaches people about other cultures and other places—something very basic and obviously lacking in the “educator” I met in New Jersey.

    Fear may be felt in the heart as well as in the head, according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.

    Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting(收缩) and pumping blood around their bodies, compared with the point when the heartbeat is relaxed. Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful event, depending on which point it is at in its regular cycle of contraction and relaxation.

    Sarah Garfinkel at the Brighton and Sussex Medical School said: “Our Study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart.”

The study tested 20 healthy volunteers on their reactions to fear as they were shown pictures of fearful faces. Dr Garfinkel said, “The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed. Thus our hearts can also affect what we see and what we don't see一and guide whether we see fear.”

To further understand this relationship, the scientists also used a brain scanner(扫描仪) to show how the brain influences the way the heart changes a person's feeling of fear.

“We have found an important mechanism by which the heart and brain ‘speak' to each other to change our feelings and reduce fear,” Dr Garfinkel said.

    “We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced, we may be able to develop more successful treatments for anxiety disorders, and also for those who may be suffering from serious stress disorder.”

    I fondly remember road trips as a child, sitting in the sunny backseat of my mom's car, daydreaming about other worlds and fantastic adventures. As I've grown older, my daydreams have become increasingly occupied less with fantasy but more with the reality of my past and future. Nearly everyone daydreams about their future and reflects nostalgically (念旧地) or negatively on moments of the past. These moments can provide inspiration, but if you spend too much time daydreaming in this fashion, you may be reducing your success in the present.

    If you've ever planned a vacation, you're familiar with the impatient days tapping at your desk, dreaming of the lazy, relaxing days to come. Unfortunately, sometimes you end up comparing the real vacation to your imagined one, and it doesn't live up to the standard. Reflecting nostalgically on the past can also prevent present enjoyment. It is equally fun to reflect on past achievements or fun events, but it's possible to be so consumed with happy memories that you miss opportunities to create more.

    We've all made mistakes that we're ashamed of; reflecting on them is an important step in correcting those mistakes and becoming a better person. But dwelling（细想）too long on your past can also be negative. If you dwell too long on a past mistake, you can begin to equate（使等同）yourself with your past and feel farther away from the person you want to be. Train your brain to think quickly about the past and future, and take only the information and inspiration that you need in order to be the best person you can without resting on your glory moments or your mistakes.

    If your identity is not dependent on the past or future, every experience is new and every day is a blank page for you to write. A fun mental exercise is to always tell yourself that you're experiencing things for the first time. So take advantage of each moment you're given.

    One morning more than thirty years ago, I entered the Track Kitchen, a restaurant where everyone from the humblest(卑微的) to the most powerful came for breakfast. I noticed an empty chair next to an elderly, unshaven man, who looked somewhat disheveled. He was wearing a worn-out hat and was alone. I asked if I might join him. He agreed quietly and I sat down to have my breakfast.

    We cautiously began a conversation and spoke about a wide range of things. We never introduced ourselves. I was concerned that he might have no money and not be able to afford something to eat. So as I rose to go back to the counter and buy a second cup of coffee, I asked,

    "May I get you something?"

    "A coffee would be nice."

    Then I bought him a cup of coffee. We talked more, and he accepted another cup of coffee. Finally, I rose to leave, wished him well, and headed for the exit. At the door I met one of my friends. He asked,

    "How did you get to know Mr. Galbreath?"

    "Who?"

    "The man you were sitting with. He is chairman of the Board of Churchill Downs."

    I could hardly believe it. I was buying, offering a free breakfast, and feeling pity for one of the world's richest and most powerful men!

    My few minutes with Mr. Galbreath changed my life. Now I try to treat everyone with respect, no matter who I think they are, and no matter another human being with kindness and sincerity.

    Planning a visit to the UK? Here we help with ways to cut your costs.

    AVOID BIG EVENTS Big sporting events, concerts and exhibitions can increase the cost of accommodation and make it harder to find a room. A standard double room at the Thistle Brighton on the final Friday of the Brighton Comedy Festival (19 Oct.) cost £169.15 at Booking.com. A week later, the same room cost £l18.15.

    If you can be flexible and want to know dates to avoid-or you're looking for a big event to pass your time—check out sites such as Whatsonwhen.com, which allow you to search for events in the UK by city, date and category.

    STAY AWAY FROM THE STATION If traveling to your destination by train, you may want to find a good base close to the station, but you could end up paying more for the sake of convenience at the start of your holiday.

    Don't be too choosy about the part of town you stay in. Booking two months in advance, the cheapest room at Travelodge's Central Euston hotel in London for Saturday 22 September was £95.95. A room just a tube journey away at its Covent Garden hotel was £75.75. And at Farringdon, a double room cost just £62.95.

    GET ON A BIKE London's 'Boris bikes' have attracted the most attention but other cities also have similar programmes that let you rent a bicycle and explore at your own pace, saving you on public transport or car parking costs.

    Among the smaller cities with their own programmes are Newcastle (casual members pay around £1.50 for two hours) and Cardiff (free for up to 30 minutes, or £5 per day).

    Hi, I'm Neil Harbisso. I come from a place where the sky is always grey, where flowers are always grey, and where television is still in black and white.

    I actually come from a world where color doesn't exist. I was born with achromatopsia. I was born completely color-blind. So I've never seen color, and don't know what it looks like. But since the age of 21, I can hear color thanks to a magic electronic eye called "eyeborg": a color sensor between my eyes connected to a chip(芯片) installed at the back of my head that transforms color frequencies into sound frequencies that I hear through my bone.

    I've had the electronic eye permanently attached to my head and I've been listening to colors nonstop since 2004. So I find it completely normal now to hear colors all the time.

    Since I started to hear color, my life has changed significantly. Art galleries have become concert halls. I can hear a Picasso. And supermarkets have become like night clubs. I love how they sound.

    My sense of beauty has changed. Someone might look very beautiful but sound terrible, and someone might sound very harmonious but look awful. So I find it really exciting to create sound portraits(画像) of people. Instead of drawing the shape of someone's face I write down the different notes I hear when I look at them, and then I send them an mp3 of their face. Each face sounds different. I can even give face concerts now, concerts where I play the audience's faces. The good thing about doing this is that if the concert doesn't sound good, it's their fault.

    I also found out that things I thought were colorless are not colorless at all. Cities are not grey. Lisbon is yellow turquoise(宝石绿); London is very golden red…and humans are not black and white. Human skins range from light shades of orange to very dark shades of orange. We are all orange.

    If we extend our senses, we will consequently extend our knowledge.
