严格来说,并不是每个人都有忘年之交的。但在我走过的岁月里,先后有过三位忘年之交——如今他们中的两位已归道山。其中最让我怀念的,是我二十岁那年结识的第一位。1977年底,高考制度恢复,我以第一志愿考取南京大学天文系天体物理专业。有一天家里来了一位奇怪的贺客:进门就对我母亲脱帽鞠躬,并称我母亲为“伯母”——那时他已经七十 Strictly speaking, not everyone has forged the year. But in the years I have passed, there have been three forfeited years - now two of them have returned to Dao Shan. One of the things I missed most was the first person I knew when I was 20 years old. At the end of 1977, the college entrance examination system was restored. I took the first aspiration to obtain astrophysics at the Department of Astronomy of Nanjing University. One day my family came home with a strange congratulatory message: When I entered the door, I took my mother off my head and called my mother “auntie”—at that time he was already seventy.
