In the beginning, E. Mavis
Hetherington was looking for as much pathology as the next person.
It was the early 1970s, with the American family in free fall, and she
fully expected that her just-launched study. of the impact of divorce would find
dysfunction and plenty of it: parents unable to cope, maladjusted children with
long-term difficulties. By almost any measure-emotional, social or ecademic-"we
expected them to blow it."
Yet here’s the surprising thing about
her families, with all their couplings and uncouplings and even recouplings
during the years that followed: the vast majority of parents rebounded from the
pain and upheaval. Resiliency overshadowed pathology. And by the time the
children were young adults, considering marriage and families of their own,
Hetherington discovered at least 75% coping fairly well--some very well--with
life.
Divorce, it seems, is not predestined.
Now
A. most of the divorced parents are hardly able to cope with its impact
B. most of the children of divorced parents find it hard to adjust themselves
C. most of the children of divorced parents do not care about their parents’ marital relations
D. most of the divorced parents can adjust themselves to the new lives
