Through the ages the experiences of childhood have been as varied as its duration. Actions
that would have provoked a beating in one era elicit extra loving care in another.Babies who have been nurtured exclusively by their mothers in one generation are left with day-care workers in another.In some places children have been trained to get through danerous mountain passes, and carry heavy objects on their heads.In other places they have been taught complicatd piano concerto.
这段话的两句Through the ages the experiences of childhood have been as varied as its duration. Actions that would have provoked a beating in one era elicit extra loving care in another.怎么理解？

贯穿于这些时期的童年经历的复杂多样,正如各人会有长短不一的童年一样。
某些举动,在某一时期可能会引发一顿打,但在另一时期可能会因此而得到额外的关爱.
