不太适合这么改写。
这里的what是疑问限定词,而非融合型关系限定词,what引导的从句与前面的where(疑问副词) their journey has taken them并列,共同作update后介词on的宾语(补足成分)。
At whatever grade level teachers find themselves, from kindergarten to the final class at medical or law school, few moments stir the emotions as deeply as when former students reappear years and often decades later with an update on where their journey has taken them and what resiliencies have been the pavement on which they’ve traveled.
请问老师们,这里的what是用作限定词限定resiliencies吗?如果是,该what分句作为on的介词补足成分,是一个宾语从句,是否能改写为resiliencies that have been the pavement?
