When I finished graduate school, in 1976, there was a job shortage in Canada for Ph.D.’s. The only position I found was with a research project studying second language acquisition in school children.

我从未想过双语到底是好是坏，我的博士学位主修的是心理学，研究小孩如何学习语言，1976年我毕业的时候，那时在加拿大非常少的工作适合心理学方面的人才，我唯一能找到的职位是一个关于少儿语言学习的研究项目。
