上课的时候，心理学老师总会从小瓶子里喝一点药水。这件事是全班同学都很感动。我们认为他应该请假在家休息，但是他却按时到每个班级上课。因此，我们所有的学生学习心理学比学习其他课程还要用功。那个学期末，我们告诉他我们有多么感激他。我们特别担心他的健康，因此我们就问他得的是什么病，服的是什么药。他露出了满意的笑容说：“我很好，那是一瓶茶水”

When we had our class, our psychology teacher take someliquid medicine from a tiny bottle. This touched the whole class. We thought that she should ask for leave and stay at home for a rest, but he came to every class on time. Therefore, all us us studied psychology harder than we did any other subject. At the end of that term, we told him how much we appreciated him. We wete so worried about her health that we asked him what disease he had got and what medicine he had taken. With a satisfying smile, he said, " I'm quite all right and it's a cup of tea."
