圈圈姐姐:你好!从小,爸爸就教我做个乐于助人的好孩子。我经常帮同学擦黑板、买文具、讲解课本上他们不懂的地方……渐渐地,班上的人都说我好说话,遇到事都喜欢让我帮忙。起初,得到别人的感谢时,我也非常高兴;可最近我发现,因为花太多时间帮同学补习,我自己的学习时间变少了,这次中考成绩下降不少。我感到力不从心,但不好意思拒绝别人的求助,我该怎么办呢?叶子 Circle sister: Hello! From an early age, my father taught me to be a helpful good boy. I often help students wipe the blackboard, buy stationery, explain the textbooks where they do not understand ... ... Gradually, people in the class say I’m good to talk, encounter things like let me help. At first, I was very happy when I got the thanks of others. Recently, however, I found out that because I spent too much time to help students tutoring, I had less time for my studies and my grades in the examination have dropped a lot. I feel powerless, but I am sorry to refuse others for help, what should I do?
