Many stories happened at the Children’s Medical Care Center,       deeply touched us. We saw a lot of children without hair because of their treatment. We played with them and taught them to draw pictures. They suffered great pains,    were very friendly. It was much easier to communicate with them than we    (expect).
One day, a girl suggested    (teach) us how to fold paper. She taught us      great patience, explaining each step slowly and clearly. Though we could easily do that, we still pretended (假装) to know nothing about it. We followed her and did everything she told us. Finally, when we finished our work    (success), she gave each of us      big hug. We could see the pride and happiness on her face. Her father was       thankful to us that he held our hands tightly, tears in his eyes. It was not until then    we knew the girl would receive an operation the next day.
It was really a valuable experience to us all. We began to think about how to deal with the difficulties in life, because    (compare) with what these kids are going through, our “troubles” seem not worth mentioning at all.
