One is that somebody came up after class and asked

第一有位同学课后来问
when the preference for your own language emerges in development

人对母语的偏好是什么时候产生的

对婴儿认知这个问题做了专业的研究

这表明他们还在子宫中孕育时
while in utero, while in the womb, to the rhythms of their language

就能察觉到母语的节奏
and developing a preference for it.

并有所偏好
