译文 自2001年起,美国一千多名高中和大学的学生加入了“塑身工程”,该工程旨在帮助女孩了解她们一直信奉的观念:只有瘦才会幸福和成功。
点睛 该句的主干是...students...have participated in the Body Project...。which引导的非限制性定语从句修饰Body Project,该从句中by引导的介宾结构作方式状语,宾语从句how they have been buying into...successful作understand的宾语,that引导的同位语从句that you have to be thin...对notion进行说明。
俚语buy into意为“随大流相信;盲从”。如:
No one can buy into that brand of liberalism. 谁也无法认同那种自由主义的作风。
