What is friendship? Different people have different opinions. In my opinion, friendship is simply a ray of sunshine. Let me tell you a true story about friendship. It was a rainy afternoon, Xiao Ling, my best friend, and I were      duty. We had to    the desks and chairs, wash the doors and windows, and sweep the school floor. We worked hard    it was getting dark.
After we finished our work, we realized that we hadn’t brought our umbrellas to school    it wasn’t raining then. All of our classmates,    Xiao Ling and me, were taken home by their parents.    noticed us and we felt lonely and afraid.
We waited and waited until Xiao Ling’s grandma came. She asked Xiao Ling to go with her. But Xiao Ling    do. She said to her grandma, “I can’t leave my friend alone.”
Xiao Ling’s grandma said, “well, let’s go first. Maybe her parents will come soon.” “Oh, no, her parents work in a faraway place. They won’t come. I can’t leave without taking her,” Xiao Ling insisted（坚持）. I was so    that tears came into my eyes. At last we shared the same umbrella in the rain. When I got home, the rain stopped. A ray of colorful     came out.
I’d heard the famous saying “A friend in     is a friend indeed” before, but not until this time did I understand its real meaning.
