                                              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 (肿胀) 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 RSL
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.
    Note: RSI abbr .肢体重复性劳损 (repetitive strain injury).

The first telephone cards, produced in 1976, were Italian. Five years later the first British card appeared, and now you can buy cards in more than a hundred countries. People usually start collecting cards because they are small and light and you do not need much space for them. It is also a cheap hobby for beginners, although for some people it becomes a serious business. In Paris, for example, there is a market where you can only buy telephone cards, and some cards cost up to ￡4,000. The first Japanese card has a value of about ￡28,000. Most people only see cards with prices like these in their collectors’ magazine.

     The first Earth Day was in 1970. People were beginning to worry about what we were doing to our
environment. So they set up Earth Day to tell everyone about their worries.
     In 2007 organizers m over 150 countries planned over 4,000 big events. But Earth Day is not just about
marches (游行) and big events. In the week around Earth Day (22 April) there were many thousands of
smaller, local events. These events dealt with environmental problems in the neighborhood.
    The World Wide Fund for Nature made a list of 5 things that each person could do to save the environment.
     * Don't leave the tap running.
     * Turn off lights when you leave a room.
     * Turn off your computer every night.
    * Wash your clothes, and yourself, in warm or cold water, not hot water.
     * Dishwashers use as little water as possible. If we all do at least 2 0f these all the time, we can make a big
difference.
