Take a look at the following list of numbers: 4, 8, 5, 3, 7, 9, 6. Read them loud. Now look away and spend 20 seconds memorizing them in order before saying them out loud again. If you speak English, you have about a 50% chance of remembering those perfectly. If you are Chinese, though, you're almost certain to get it right every time. Why is that? Because we most easily memorize whatever we can say or read within a two-second period. And unlike English, the Chinese language allows them to fit all those seven numbers into two seconds.

    That example comes from Stanislas Dahaene's book The Number Sense. As Dahaene explains: Chinese number words are remarkably brief. Most of them can be spoken out in less than one-quarter of a second (for instance, 4 is “si” and 7 “qi”). Their English pronunciations are longer. The memory gap between English and Chinese apparently is entirely due to this difference in length.

    It turns out that there is also a big difference in how number-naming systems in Western and Asian languages are constructed. In English, we say fourteen, sixteen, seventeen, eighteen and nineteen, so one might expect that we would also say oneteen, twoteen, threeteen, and fiveteen.  But we don't. We use a different form: eleven, twelve, thirteen and fifteen. For numbers above 20, we put the “decade” first and the unit number second (twenty-one, twenty-two), while for the teens, we do it the other way around (fourteen, seventeen, eighteen). The number system in English is highly irregular. Not so in China, Japan, and Korea. They have a logical counting system. Eleven is ten-one. Twelve is ten-two. Twenty-four is two-tens-four and so on.

    That difference means that Asian children learn to count much faster than American children. Four-year-old Chinese children can count, on average, to 40. American children at that age can count only to 15. By the age of five, in other words, American children are already a year behind their Asian friends in the most fundamental of math skills.

    The regularity of their number system also means that Asian children can perform basic functions, such as addition, far more easily. Ask an English-speaking seven-year-old to add thirty-seven plus twenty-two in her head, and she has to change the words to numbers (37+22). Only then can she do the math: 2 plus 7 is 9 and 30 and 20 is 50, which makes 59. Ask an Asian child to add three-tens-seven and two-tens-two, and then the necessary equation(等式) is right there, in the sentence. No number translation is necessary: it's five-tens-nine.

When it comes to math, in other words, Asians have a built-in advantage. For years, students from China, South Korea, and Japan — outperformed their Western classmates at mathematics, and the typical assumption is that it has something to do with a kind of Asian talent for math. The differences between the number systems in the East and the West suggest something very different — that being good at math may also be rooted in a group's culture.

    A car dealership in my hometown of Albuquerque was selling six to eight new cars a day. I was also told that 72 percent of this dealership's first-time visitors returned for a second visit.

    I was curious. How does a car dealership get 72 percent of its first-time visitors to return? And how can they sell six to eight cars a day in a declining car market?

    When I walked into Saturn of Albuquerque that Friday, the staff there didn't know me from Adam; yet they shared with me their pricing policy, the profit margin on every model, and staff income. They even opened their training manuals for my review and invited me back on Saturday if I wanted more information.

    On Sunday, the day after my second visit to the Saturn store, my wife, Jane, and I were walking as we frequently do. On this particular June morning, Jane gently slipped her hand in mine and said tenderly, ＂I don't know if you remember, but today's my fifth anniversary of being cancer-free.＂ I was surprised, partially because I was embarrassed that I had forgotten and, partially because.... Well, I didn't know what to do with Jane's information.

    The next day, Monday, Jane went off to work teaching school. Still not knowing what to do to mark this special occasion, I did the most impetuous thing I've ever done in my life: I bought a new Saturn. I didn't pick the color or the model, but I paid cash and told them I'd bring Jane in on Wednesday at 4:30. I told them why I was buying the car.

    On Tuesday, it dawned on me that Jane always wanted a white car. I called the sales consultant at Saturn, and I asked him if he had anything white in the store. He said he had one left but he couldn't guarantee it'd still be available on Wednesday at 4:30 because they were selling so fast. I said I'd take my chances and asked him to put it in the showroom.

    Wednesday came. Unexpectedly, someone in our family was admitted to the hospital. So, it wasn't until 9:30 Saturday morning when we finally made our way to the Saturn store. Jane had never been in a Saturn store. When we went through the front door, the Lord took control of her feet and her mouth. She saw that little white Saturn coupe all the way across the showroom floor. She quickly passed a multi-colored sea of automobiles, sat in the little white Saturn and said, ＂Oh, what a pretty little car. Can I have a new car?＂ I said, ＂No. Not until our son graduates from college.＂ She said, ＂I'm sick and tired of driving that old Dodge, I want a new car.＂ I said, ＂I promise, just three more semesters and he'll be out.＂

    Next, Jane walked around to the front of the car. As she looked it over, she let out the most blood-curdling, shrill scream I'd ever heard in 29 years of marriage.

    Now, before I tell you why Jane screamed, let me tell you what the sales consultant had done. He had ordered a large, professionally engraved sign (white letters on blue). The sign stood alone on the hood of the little white Saturn coupe. It said ＂Congratulations, Jane. This car is yours. Five years cancer-free. Let's celebrate life. From Team Saturn＂ Every employee at Saturn of Albuquerque had signed the back of that sign.

    Jane saw it, screamed, collapsed in my arms and cried loudly. I didn't know what to do. I was in tears. I took out my invoice (发票) from the previous Monday, pointing to the white coupe, said, ＂No, honey, this car isn't yours. I bought you this one.＂ I tapped the invoice with my index finger. Jane said, ＂No, I want this one right here.＂

    While this conversation was going on, there was no one in the store. The sales consultant had arranged it so that we could share the moment alone. Even so, it's impossible to have a lot of privacy when so many people are standing outside the showroom windows looking in. When Jane screamed and collapsed in my arms, I saw everybody outside applaud and begin to cry.

    Once upon a time, there was a lovely vegetable field, on which grew a very thick tree. Both the vegetables and the tree gave the place a wonderful appearance, which was the joy of the garden's owner. What no one knew was that the vegetables in the field and the tree couldn't stand each other. The vegetables hated the tree's shadow, because it left them only just enough light to survive. The tree, on the other hand, hated the vegetables because they drank nearly all the water before it could get to him, leaving him with just enough to survive.

    The situation became so extreme that the vegetables got totally fed up and decided to use up all the water in the ground so that the tree would dry up. The tree answered back by refusing to give the vegetables shadow from the hot midday sun, so they both began to dry up. Before long, the vegetables were really thin and the tree's branches were drying up.

    Neither of them thought that the gardener, on seeing his vegetable field becoming worse, would stop watering it. When he did that, both the tree and the vegetables really learned what thirst was. There seemed to be no solution, but one of the vegetables, a small courgette（小胡瓜）, understood what was going on, and decided to deal with it. Despite the little water and the unbearable heat, the little courgette did all he could to grow, grow... He managed to grow so big that the gardener started watering the field again. The gardener wanted to enter that beautiful big courgette in some gardening contest.

    They should really learn how to live in harmony）with those around them, doing the best they could. So they decided to work together, and help each other instead of fighting, using both the shadow and the water in the best combination to grow good vegetables. Seeing how well they were doing, the gardener now gave the best of care to his vegetable field, watering it better than any other field for miles around.

    In Africa, Christmas Day begins with groups of carolers (欢唱颂歌的人) walking to and from through the village, along the roadway, by the houses of the missionaries (传教士), singing the lovely carols known to the world around. Often people may be awakened by a group of carolers beginning to gather at the house of worship(敬神活动). They return home to make final preparations as to the clothes one must wear and also as to their offering for the Christmas service.

    The most important part of their Christmas worship service is the love offering. This is the gift in honor of Jesus. At about 8 or 9 o'clock everyone goes to the celebration of the birthday of Jesus. Everyone who attends the service goes forward to lay down their gift upon the raised platform near the Communion table. No one will attend the service without giving a gift.

    Christmas in South Africa is a summer holiday. There is no snow, but it has many flowers, many beautiful varieties of wild flowers being in their full pride.

    In Ghana, most churches show the coming of Christmas by decorating the church and homes beginning with the first week in Advent, four weeks before Christmas. This season happens to be the time of cocoa harvest, so it is a time of wealth. Everyone returns home from wherever they might be such as farms or mines.

    In Africa, it is the traditional dinner of turkey, roast beef, mince pies, or suckling pig, yellow rice with raisins, vegetables, and plum pudding, crackers. In the afternoon, families go out into the country and usually there are games or bathing in the warm sunshine, and then home in the cool of the evening. Boxing Day is also a proclaimed (正式宣布的) public holiday usually spent in the open air. It falls on December 26 and is a day of real relaxation.

Many scientists today are convinced that life exists elsewhere in the universe—life probably much like that on our own planet. They reason in the following way.

    As far as astronomers can determine, the entire universe is built of the same matter. They have no reason to doubt that matter obeys the same laws in every part of the universe. Therefore, it is reasonable to guess that other stars, with their own planets, were born in the same way as our own solar system. What we know of life on earth suggests that life will arise wherever the proper conditions exist.

    Life requires the right amount and kind of atmosphere. This eliminates(除去) all those planets in the universe that are not about the same size and weight as the earth. A smaller planet would lose its atmosphere; a larger one would hold too much of it.

    Life also requires a steady supply of heat and light. This eliminates double stars, or stars that flare up suddenly. Only single stars that are steady sources of heat and light like our sun would qualify.

    Finally, life could evolve(进化) only if the planet is just the right distance from its sun. With a weaker sun than our own, the planet would have to be closer to it. With a stronger sun, it would have to be farther away.

    If we suppose that every star in the universe has a family of planets, then how many planets might support life? First, eliminate those stars that are not like our sun. Next eliminate most of their planets; they are either too far from or too close to their suns. Then eliminate all those planets which are not the same size and weight as the earth. Finally, remember that the proper conditions do not necessarily mean that life actually does exist on a planet. It may not have begun yet, or it may have already died out.

    This process of elimination seems to leave very few planets on which earthlike life might be found. However, even if life could exist on only one planet in a million, there are so many billions of planets that this would still leave a vast number on which life could exist.

I've just arrived from New York City at the airport in Rome and already I'm lost, wandering left and right and searching for the right exit. I'm supposed to meet my wife Elvira, who lives in Italy now, and then drive to Guardia Sanframondi, the little town where we own a house, to meet our newborn granddaughter Lucia, now all of 11 weeks old.

But I takes a wrong turn, and then another, all in vain. I'm lost for 15 minutes, then 30, and finally about 45, unable to get my passport properly scanned and pick up my luggage. This is more than mildly inconvenient. After all, I've just flown more than 4,000 miles, a flight into my future.

But suddenly I see Elvira, who is holding baby Lucia in her arms. I'm found.

I stay in Italy for three weeks. It's impossible for me to get enough of Lucia, and so I follow a strict agenda(日程). Hold Lucia in my arms. Kiss Lucia all over her face. Wheel Lucia in her carriage in the most public places available. Make faces at her and even sillier gestures and sounds.

Today, at 70, I'm a permanent resident of Italy, with Lucia living a five-minute walk away. We visit her at her house and she visits us at ours almost every day. In most American families, adult children with grandchildren live in different towns and states far away. Italian families, on the other hand, are more likely to live near each other. Sometimes three generations here even stay together in the same home. I've happily turned my life upside-down to be a grandpa Italian-style. Lucia is just what I need right about now. If I'm lucky, I'll be just what she needs, too.
