One day，I took my daughter to the park．As soon as we got there，my daughter （run） to the swing （秋千）and asked for a push．When I was helping my daughter，I noticed another girl trying to make her own swing （go） high by herself．Her old grandmother was sitting on the chair nearby and smiling at us．Gradually，my daughter （push） higher and higher by me．

    Then I walked towards the little girl．I asked if I （give） a big push to her．She smiled and said “Yes”． For the next hour，I pushed the swings，and played with my daughter and the little girl． When we went home，I （be） tired but very happy．

    One day two years later，after a day's work，I went to pick up my daughter before going home．

    While I （wait） outside the school gate，a little girl smiled sweetly at me and gave me a big hug．As I watched her （run） away，I realized that she was the girl whom I gave a big push in the park．

    So far，I （not forget） her sweet smile and the warm hug that she gave me．

    In fact，if we give love to others，love （find） its way back to us．It may travel from heart to heart or it may blossom （开花）in the heart．The love we share，the kindness we （give），and the happiness we create will come back to us with a pleasant surprise．
