八、閱讀短文．根據(jù)短文內(nèi)容回答問(wèn)題．（共10分，每小題10分）

• 18．Thumbs Don to Texting 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 cause us problems with our hands．Be careful!Too much texting can cause swelling（腫脹） in our thumbs．Our thumbs were not made for pushing small buttons over and over，Scientists call this problem repetitive strain injury（RSI）．Harrier Wilson，who treats many sick people with RSI，says we need to see how much time we are spending in typing text messages．If we are spending more than 10 minutes 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 computers and mobile phones．If we don't do something about this，many of us could grow up in terrible pain．
  
  （1）What is becoming very popular now？

  
  （2）What behaviour can cause us to have RSI in the future？

  
  （3）Who is easier to have the problem of RSI？

  
  （4）What can also cause RSI except texting？

  
  （5）Which is easier to cause the problem of RSI，using smaller mobile phones or larger ones？
