When I opened the envelope,coins and dollar bills fell out — fives,tens,twenties.At that moment,my throat tightened with emotion and I understood the meaning behind their excited faces.An overwhelming sense of pride from them washed over me.Should I take it?My brain was spinning fast.Seeing the money that the students raised,I couldn't help but wonder another question:How had these kids collected so much money?【高分句型一】I could even imagine the countless hours they had spent working odd jobs,determined to save every penny to help me.Therefore,deep within my heart.there was a firm voice. "I can't take it ?"(描写了作者看到这些钱时的内心活动)
As an adult in the room,I felt guilty and unwilling to accept these teenagers' hard﹣earned money,but I decided to accept it.I tightly held up the cash and my voice trembled as I told them how I was bothered by the cost of parking. 【高分句型二】"Kids,you just covered my parking cost for the month." But that's not the real reason why I accepted it.With tears of gratitude welling up in my eyes,I hugged each student tightly.More important than the envelope was the kindness in their hearts and the lesson they had taught themselves:how wonderful it feels to meet someone's needs and to make a difference.Through their small act of kindness,these teenagers have shown me their growth and they are not ignorant children,but young individuals with wisdom and kindness in their hearts.(描写了作者对学生这个善举的感谢)
