完形填空

People in communities have slowly been pushed apart through the years, mostly because people simply aren’t taking the time to say a simple “hello”. After considering this phenomenon, I decided I was going to change the way I got on    小题1:  others.

My opportunity came one morning when I was in the community library. I passed by a girl  小题2:  dropped her books out of her locker.  小题3:   (think) that someone else would help her pick them up, I continued  小题4:  way. However, when I had to go back  小题5:  I forgot my book, I noticed she had just finished picking them up by herself. No one had stopped 小题6:   (help) her.

“OK,” I thought to myself, “this is where I should have changed.”

My best opportunity came a few days later when I saw a man sitting by himself waiting for the library to open, so I sat down next to him and  小题7:  (begin) a conversation.   小题8:  was difficult to get started ,and even when I had to say goodbye, almost every response from my new friend had a tone (语气) of doubt in it .And who could blame him?

People aren’t used to making  小题9:  unprepared chat with a stranger. But a change, no matter how desperately it is needed, doesn’t just happen. It takes people like us to make it possible. I advise you to take a small step out of your comfort zone and try to make someone’s day a little  小题10:  

(bright) .Together, we can really make our society come closer as a whole.
