When I was young, I didn’t have a brother or sister, so I was always alone.

One day, something unexpected     1     (change) me suddenly, which is the best memory that I will cherish     2    my heart forever. That day I got up and opened the window of my bedroom, but the weather outside was very cold, so I decided     3     (close) the window. Just at that moment, a blue bird flew in. I was very     4    (surprise). Then it hit the door and fell onto the ground. I went over to look at it     5     (immediate). That bird was young, whose wings were hurt. I thought it was the reason     6     it got into my house.

I decided to help the bird. At     7     very beginning, it was very afraid of me and made loud noise, always       8     (refuse) to eat and drink. However, it slowly accepted me and the wounds got better day by day. I was glad about its     9     (recover). A few days later, the bird fully recovered, and I decided to let it go. When it left my hand and flew away, it looked back at me, just like expressing its     10     (thank) to me.
