     More surprising, perhaps, than the current difficulties of traditional marriage is the fact that marriage

itself is alive and thriving (兴盛)。As Skolnick notes, Americans are marrying people-relative to

Europeans, more of us marry and we marry at a younger age. Moreover, after a decline in the early 1970s,

the rate of marriage in the United States is now increasing. Even the divorce rate needs to be taken in this

pro-marriage context: some 80percent of divorced individuals remarry. Thus, marriage remains, by far,

the preferred way of life for the vast majority of people in our society.

     What has changed more than marriage is the nuclear family. Twenty-five years ago, the typical American

family consisted of a husband, a wife and two or three children. Now, there are many marriages in which

couples have decided not to have any children. And there are many marriages where at least some of the

children are from the wife's previous marriage, or the husband's, or both. Sometimes these children spend

all their time with one parent from the former marriage; sometimes they are shared between the two former

spouses.

      Thus, one can find the very type of family arrangement. There are marriages without children; marriages

with children from only the present marriage; marriages with full time children from the present marriage and

part time children from former marriages. These are stepfathers, stepmothers, half-brothers, and half-sisters.

It is not all the unusual for a child to have four parents and eight grandparents! There are enormous changes

from the traditional nuclear family. But even so, even in the midst of all this, one thing remains constant: most

Americans spend most of their adult lives married.

A. more of Americans, as compared with Eroupeans, prefer marriage and they accept it at a younger ate.

B. Many types of family arrangements have become socially acceptable.

C. Americans prefer to have more kids than before.
