My English professor once launched into a lecture on "motivation." "What pushes you ahead?" he asked. "What is it that makes you go to school each day? What driving force makes you strive to accomplish?" Turning suddenly to one young woman, he demanded: "What makes you get out of bed in the morning?" The student replied: "My mother."我们英文课的教授有一次在课上讲“动机”。“是什么推动你在人生的路上向前走？”他问道，“是什么让你每天上学来？又是什么驱使你追求成功？”冲着一个女学生，他问：“是什么让你早晨从床上爬起来的呢？”学生答道：“我妈妈。”
