The Sun comes up, and the cleaner starts his day. He gets his broom and he is     37     his way. He cleans up things that people drop. From dawn     38     dusk, he never     39     (stop). He sweeps the streets, and makes them     40     (clean). And he helps keep     41     (us) city green.

Night is falling,     42     the sky is dark. The only sounds     43     (be) dogs that bark. The policemen drive along the streets all night     44     (stop) thieves and those who fight. It is     45     dangerous job, but they are brave. They help keep our city     46     (safely).

One day, I took my daughter to the park. As soon as we got there, my daughter     47     (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     48     (go) high by herself. Her old grandmother was sitting in the chair nearby and smiling at us. Gradually, my daughter was pushed higher and higher     49     me. Then I walked towards the little girl. I asked if I     50     (can) 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     51     (be) tired but very happy.

One day two years later, after a day’s work, I went     52     (pick) up my daughter before going home.       

While I     53     (wait) outside the school gate, a little girl smiled sweetly at me and gave me a big hug. As I watched her     54     (run) away, I realized that she was the girl whom I gave a big push in the park.

So far, I haven’t forgotten her sweet smile and the warm hug that she gave me.

In fact, if we give love to others, love     55     (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     56     (give), and the happiness we create will come back to us with a pleasant surprise.
