有些同志認爲在高等學校裏做教學工作,和在研究機構裏從事研究是很難兼顧的,如果一身而兼兩職,那就會發生困難,造成損失。但是根據我一年來的親身體驗,覺得這樣做沒有壞處,只有好處。我原是北京大學的專任教授,1953年春,領導上減輕了我的教學任務,准許我兼任中國科學院新成立的動物研究室主任。這樣的合作對北京大學並不是不利的,因爲單是動物研究室的成立對對北京大學生物學系動物學專業就起了一些好的作用。在動物研究室成立以前,動物學專業一部分同學的學習情緒是不安定的。那時,他們看到中國科學 Some comrades think that it is very difficult to do teaching work in higher education institutions and to conduct research in the research institutes. If both are employed concurrently, difficulties and losses will result. However, based on my personal experience over the past year, I feel that there is no harm in doing so and that there are only benefits. I was originally a full professor at Peking University.
