If you have ever been left wondering why your emails are riddled(充斥着) with grammatical errors, or why you can never quite find the right phrase, it may be because you are typing with both hands.

    Our vocabulary becomes richer and our writing style becomes more fluent when we type using just one hand, scientists have found. "Typing can be too fluent or too fast, and it can actually weaken the writing process," said Srdan Medimorec, the lead author of the study conducted at the department of psychology at the University of Waterloo, Canada. "It seems that what we write is a product of the interaction(互动) between our thoughts and the tools we use to express them."

    Using text-analysis software, researchers asked 103 university students to write essays under different conditions, using one hand to type and using both hands to type. The software was used to analyze(分析) elements of the essays, such as range of vocabulary, sentence complexity and the cohesion(衔接) of the writing.

    Researchers found that participants' vocabulary became more advanced when they typed with one hand rather than two. The research team said that by slowing our writing down, typing one-handed allows more time for an internal (内在的) word search, resulting in a larger variety of words.

    In contrast, fast typists might just write the first word that comes to mind. However, it is important not to slow typing down too much. Those who typed essays one-handed in the current study slowed down to about the speed of handwriting.

    This is the first study to show that changing people's typing can make their writing get better. The researchers suggested that the speed of writing could affect writing quality regardless of the tools used, whether they are computers, or pen and paper, although further research would be required to prove that idea.

    When my brother and I were young, my mom would take us on Transportation Days.

    It goes like this: You can't take any means of transportation more than once. We would start from home, walking two blocks to the rail station. We'd take the train into the city center, then a bus, switching to the tram, then maybe a taxi. We always considered taking a horse carriage in the historic district, but we didn't like the way the horses were treated, so we never did. At the end of the day, we took the subway to our closest station, where Mom's friend was waiting to give us a ride home—our first car ride of the day.

    The good thing about Transportation Days is not only that Mom taught us how to get around. She was born to be multimodal (多方式的). She understood that depending on cars only was a failure of imagination and, above all, a failure of confidence—the product of a childhood not spent exploring subway tunnels.

    Once you learn the route map and step with certainty over the gap between the train and the platform, nothing is frightening anymore. New cities are just light-rail lines to be explored. And your personal car, if you have one, becomes just one more tool in the toolbox—and often an inadequate one, limiting both your mobility and your wallet.

    On Transportation Days, we might stop for lunch on Chestnut Street or buy a new book or toy, but the transportation was the point. First, it was exciting enough to watch the world speed by from the train window. As I got older, my mom helped me unlock the mysteries that would otherwise have paralyzed my first attempts to do it myself: How do I know where to get off? How do I know how much it costs? How do I know when I need tickets, and where to get them? What track, what line, which direction, where's the stop, and will I get wet when we go under the river?

    I'm writing this right now on an airplane, a means we didn't try on our Transportation Days and, we now know, the dirtiest and most polluting of them all. My flight routed me through Philadelphia. My multimodal mom met me for dinner in the airport. She took a train to meet me.

    Jack Ma is the founder and CEO of Alibaba Group. He was one of the 100 global "future leaders" of the 2001 World Economic Forum and the "commercial leader" of 2001 elected by US Commercial Association of Asia.

    Born in the city of Hangzhou, Zhejiang Province, Ma graduated from Hangzhou Teachers Institute in 1988 (he failed the entrance exam twice) and became a lecturer in English and International Trade.

    In 1985, a one-month visit to see an Australian pen pal he had met in Hangzhou changed his life. "Everything I'd learned in China was that China was the richest country in the world," he said. "When I arrived in Australia, I realized it's totally different. I started to think you have to use your own mind to judge, to think." After his return, Ma became the chairman of the Students' Union of the whole city.

    Jack Ma founded Alibaba.com in 1999, a China based business to business marketplace site. In 2003, Alibaba launched Taobao.com, a consumer to consumer auction (消费者拍卖) website similar to eBay.

    Ma said that he got most of his ideas while taking very long, hot showers. He likes to spend time walking his four dogs and playing chess and poker. He said, "I've learned a lot of business philosophy by playing poker."

    Looking ahead, Ma said that he dreamed of using his group's resources to improve the lives of all Chinese people, especially the 900 million farmers. "There must be some way of using our experience, our know-how, and make their life easier," he said.

    If anyone knows what makes a great children's book,it must be Sussex author and illustrator(插图家) Jane Hissey. Her " Old Bear" books have achieved classic status in a variety of formats.

    I caught up with Jane at her home in the East Sussex countryside and asked her what she thinks is the secret of a classic children's book. "That's a difficult one. I suppose it's got to be relevant to the child's stage of development-for young children, pictures on a page that are familiar, for older children, an experience. The book should be familiar,but hold some surprises too to keep the interest. It must inspire and delight, but there are the things that happen every day. "

    After the birth of her first child,she gave up teaching and worked on her own artwork, drawing pictures of teddy bears. An editor from a publishing company saw her work and invited Jane to do a children's book. Over the years, from the first " Old Bear" book in 1988,her children have made a huge contribution-not least in terms of plot. She said, "I used to give my children the toys to play with-and they had tea parties and so on. One of my bear characters,"Little Bear",is the same age as Ralph, my youngest, who's seven now. All the children have joined in my work and,in years to come, they will realize how much. "

    "I hope I'll know when people are getting tired of the characters. If ever they did, I think I'd go on drawing them for fun," Jane continued," My own children have been very useful to me in my work, but as they are older now, I'll just have to hope that other people's children can inspire me. "

    There was a gardener who looked after his garden with great care. To water his flowers, he used two buckets(水桶). One was a shiny and new bucket. The other was a very old and dilapidated one, which had seen many years of service, but was now past its best.

    Every morning, the gardener would fill up the two buckets. Then he would carry them along the path, one on each side, to the flowerbeds. The new bucket was very proud of itself. It could carry a full bucket of water without a single drop spilled (溢出). The old bucket felt very ashamed because of its holes: before it reached the flowerbeds, much water had leaked（泄漏）along the path.

    Sometimes the new bucket would say, “See how capable I am! How good it is that the gardener has me to water the flowers every day! I don't know why he still bothers with you. What a waste of space you are!”

    And all that the old bucket could say was, “I know I'm not very useful, but I can only do my best. I'm happy that the gardener still finds a little bit of use in me, at least.”

    One day, the gardener heard that kind of conversation. After watering the flowers as usual, he said, “You both have done your work very well. Now I am going to carry you back. I want you to look carefully along the path.”

    Then the two buckets did so. All along the path, they noticed, on the side where the new bucket was carried, there was just bare (光秃秃的) earth; on the other side where the old bucket was carried, there was a joyous row of wild flowers, leading all the way to the garden.
