No one in my family can understand why so many of our bikes have disappeared. My mum told me
11 bikes of my family had been stolen (被偷了).
     I think it is funny, like my family has become a small shop giving out bikes for free. The number of
missing bikes is growing, so I can't help worrying. Is there someone who is crazy about my family's
bikes? Maybe he minks our bikes are the most beautiful ones around.
     I often leave my bike somewhere and return to find that it has disappeared. Nobody knows where the
missing bike has gone as if it has grown wings and flown away.
     One day last year, I locked my bike near our flat and went upstairs to get something. Thirty minutes
later, it was gone. My mum happened (碰巧) to see it on the street recently, but it was no longer mine.
The thief bad sold it to someone else. I really hate the thieves.
     Sometimes I calm down and try to understand why the thieves act as they do. Maybe they lost their
jobs and need money to support their families. But what they do really hurts others. Nobody has the right
(权利) to hurt others for his own sake.
     Everyone in the world is connected. One person's action can have a great effect on another's life. I
wish the thieves would stop taking my family's bikes. I wish the thieves would stop hurting my family.
