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 80 percent 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 of 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. There 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.

1. By calling Americans marrying people the author means that ______.

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

B. Americans expect more out of marriage than Europeans

C. there are more married couples in USA than in Europe

D. Americans are more traditional than Europeans

2. Which of the following can be presented as the picture of today's American families？

A. A typical American family consists of only a husband and a wife.

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