我在美国旧金山访学时,经常会到一位生物学老教授家中做客。这位上了年纪的教授已经几乎不去学校讲课了,只是偶尔给几个研究生上上课。每天除了看看书、写写文章外,他总会花上四五个小时开着小船到近处的河中垂钓。老教授是一个开朗健谈的人,我到他那里做客,他总会拉着我看各种收集来的资料。 When I was visiting San Francisco in the United States, I often came to visit a biologist professor home. The elderly professor has almost no school lectures, but occasionally to several graduate school classes. In addition to daily reading and writing articles, he always spent four or five hours driving a boat to the nearby river fishing. The old professor was a cheerful and talkative person. When I came to him for a treat, he always took me to look at all kinds of information collected.
