One day I was walking to the mailbox with my dad，when I saw something drop from a tree.I couldn't      what it was,so I kept my eyes on the spot as we came near .It was a baby bird,which had fallen from its nest.It had long,awkward wings and feet,and      that fought to stay open .It was      , so I sat next to it watching while my dad got the mail.I     its nest and mother ,     what would happen to it.

    My dad and we had to      it;there was nothing we could do.He said if the bird mother smelled any traces(踪迹) of      ,she wouldn't go near the      again.

    As we began to walk away,a woman      .”Did it fall out of a nest ?”she asked.

    “Yeah.”I answered.

    “It      a lot. Not much we can do,”she said .”Try not to think about it when you go to sleep tonight.”

    I walked      the mailbox the next day.The baby bird lay      in the grass.

    I realize that “Try not to think about it” is the      of many people towards things which   to provide them with perfect excuses      not bothering . The woman wasn't being     ; she was actually quite nice. But when everyone says”there's      I can do —just try not to think about it，”Where will we finally     ? When billions of people      try not to think about it When they go to bed at night, there might be millions of fallen birds lying dead and      in the grass the next morning.
