笔者为李荣老师在上世纪五十年代所办语音班的学员,此后数十年间又多次幸获李荣老师的谆谆教诲。老师的学问举世皆知,老师的师德没齿难忘。今年是李老师仙逝十周年,谨为此文以作我们数十年师生情谊的纪念,并与学界年轻朋友分享李荣老师一些极为珍贵的学术思想。 The author is a teacher of Li Rong’s phonetic class in the 1950s. Since then, he has repeatedly won over the teachings of Li Rong teacher over the past few decades. The knowledge of the teacher is well known in the world, the teacher’s morality is unforgettable. This year is the 10th anniversary of Miss Li. We would like to dedicate this article to commemorate the friendship between teachers and students for decades and to share some extremely valuable academic ideas of Li Rong with our young friends.
