Mr． Reynolds， my teacher， hand us a list of thoughts， and asked us to write a paper on one of those thoughts． I chose the topic "I wonder why things are the way they are．"

   I wrote down all the questions that puzzled（困扰）me about life． I realized that many of them were hard to answer， and perhaps others could not be answered at all． When I handed in my paper， I was afraid that I might fail because I did not answer the question．

   The next day， Mr． Reynolds handed me the paper and asked me to read it for the class． The other students became quiet as I began to read my story：

   Mum， why are the roses red？ Why is the grass green and the sky blue？ Why do I have to graduate（毕业）？ Why do I have to grow up？ Why do I have to be called "Grandma" ，one day？…

   Dad， why can't I stay out until 12： 00？ Why do I miss my old friends？ Why do I miss being at home？ Why do you love me so much？．．

   Mum， Dad， why did you have to leave me？ I need you．

   At the end of my story， I looked at Mr． Reynolds， and I saw a tear slowly coming down his face．Then I realized that life is not built on the answers we receive， but on the questions we ask．
