Thumbs Down to Texting （屈指发短信）

       Do you have a mobile phone? Do you send text messages to your friends and family?

       Text messaging or “texting” is becoming very popular. But, scientists have discovered that texting can give us problems with our hands. Be careful! Too much texting can cause swelling in our thumbs. Our thumbs were not made for pushing small buttons, over and over. Scientists call this problem RSI. We spoke to a doctor called Harriet Wilson, who treats many sick people with RSI. She says we need to see how much time we are spending in typing text messages. If we are spending more than 10–15 minutes at once, we could have problems in the future.

       As mobile phones develop, they are getting smaller with buttons closer together. Texting with a smaller phone is worse than using a larger phone with bigger buttons. Using a computer keyboard and playing video games can cause the same problem. So more and more people could find themselves with RSI. Among them, most are university students and teenagers, as they do not know the risks of spending so much time using computer, video games and mobile phones. If we don't do something about this, too many young people could grow up in terrible pain.

    One year, two Australians，Adam and Stephen，decided to go to Jamboree(童子军大会)by bike．It was in Sweden，about 20，000 kilometers from their home in Adelaide! They didn't take normal bikes；they took bikes with three wheels instead．These are more comfortable and easier to ride up hills．

    They took everything they needed．They had a tent each，things to cook with，clothes，maps，computers and phones，and things to repair the bikes．They also took their passports (护照)because they planned to travel through 22 different countries．

    The journey began in Australia but it didn't go well．After just a few days，Adam's bike broke．He left Stephen and went back home by coach (长途汽车)．He got a new wheel for his bike，then bought a plane ticket and flew to Perth．In Perth, he took a train to a town called Merridien．After he got off the train，he put his bike together and rode to meet Stephen．

    After that，they flew to Johannesburg and then they began their bike ride though Africa. They slept in tents by the road，and in some places they saw a lot of wild(野生的)animals .One night, they could hear lions ,and another night , an elephant walked past their tents．

In Europe, they rode up some very high mountains．And the most wonderful  thing， they thought，was that they saw snow for the first time in their lives．

    In every country，along the way，Adam and Stephen met a lot of interesting people and had lots of interesting people and had lots of adventures(奇遇)．The journey took 269 days．

    A bookstore chain(连锁书店), “Popular Bookmall(大众书局)” introduced their unique style of book distribution(分布) in Shanghai back in November. This experimental store offers books at very low prices, and there is no staff(职员) to require shoppers to pay before taking books away. Sounds like a book lover's paradise(天堂)！

    Popular Bookmall had already set up such a shop in Nanjing. The organizers of the Nanjing store report that it was a great success, enough shoppers voluntarily paid for their books. But most older “honesty stores” in China did not receive enough honest shoppers. For example, a shelf-service restaurant opened in Fujian province years ago which allowed shoppers to pay whatever they chose, but about one –fifth of shoppers paid nothing. Therefore some people have speculated(推断) that Chinese are becoming more honest. The organizers of the “honesty stores” say that their goal is to encourage people in China to remember how important honesty is.

    Many are cared about dishonesty in China. Even at Popular Bookmall, not everybody choose to pay for their books. How can we encourage ourselves to be honest? We should listen to our conscience(道德心). This has deep roots in Chinese culture. Confucius(孔子) taught Chinese to be conscientious and honest.

    But there is also a great rational(合理的) reason for “honesty stores”: the more honest people there are in society, the more reasons we have to trust others. And if people trusted each other, they'd be more willing to share. We could contribute to a “sharing economy” where you do not have to think about saving or spending money all the time, but helping other people. For all these reasons, society is built on trust, not only trade.
