　More surprising, perhaps, than the current difficulties of traditional marriage is the fact that marriage itself is alive and thriving（旺盛的）. As Skolnich notes, Americans are a marrying people: relative to Europeans, more of us marry and we marry at a younger age. Moreover, after a decline（衰退）in the early 1970s, the rate of marriage in the United States is now increasing. Even the divorce（离婚）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 the people in our society.

　　What has changed more than marriage is the nuclear family. Twenty-five years ago, the typical American family consisted of the husband, the 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（配偶）．

　　Thus, one can find every type of family arrangement. There are marriages without children; marriages with children from only the present marriages; marriages with“full-time”children from both the present and former marriages; 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 that unusual for a child to have four parents and eight grandparents! These are enormous changes from the traditional nuclear family. But even so, even in the midst of all this, there remains one constant: most Americans spend most of their adult lives married.

By calling Americans a marrying people the writer means that ________.

　　A. Americans are more traditional than Europeans

　　B. Americans expect more out of marriage than Europeans

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

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

Divorced Americans ________ .

　　A. prefer the way they live                   B. will most likely remarry

　　C. have lost interest in marriage               D. are the majority of people in the society

Which of the following can be presented as the picture of today’s American families？

　　A. Different types of family arrangements have become socially acceptable.

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

　　C. Americans prefer to have more kids than before.

　　D. There are no nuclear families any more.

Though great changes have taken place in the structure of American families, ________ .

　　A. the majority of Americans still have faith in marriage

　　B. the functions of marriage remain unchanged

　　C. most Americans prefer a second marriage

D. most Americans prefer to be single

At the time my son was born in 1956, I shared a hospital room with a young woman who bore a boy on the same day. Partly because my parents  46 a shop selling flowers, the room was soon  47  with the lovely scent of roses.
　  As the seventh floral arrangement was   48  , I was beginning to feel  49 , for no flowers had arrived for my roommate, Ann. She sat on the edge of her bed and leaned forward to admire the  50  bouquet. She was a pretty young woman, yet there was something about her large, brown eyes that made me think she had known too much  51 , too much sadness for one so young. I had the feeling she had always had to admire someone else’  52  .
　 “I’m enjoying every  53 of this”, she said as though she had read my   54  and was trying to reassure me. “Wasn’t I the lucky one to get you for a   55 ？”
　  I still felt uncomfortable, however.  56   there were some magic button I could push to  57   the sadness in her eyes. Well, I thought, at least,I can see that she has some flowers. When my mother and father came to see me that day, I asked them to send  58 some.
　　The flowers arrived just   59  Ann and I were finishing supper.
　　“More flowers for you,” she said,   60  .
　　“No, not this time,” I said, looking at the     61   “These are for you.”
　　Ann stared at the blossoms a long time, not saying anything. She ran her 62  across the pale blue bouquets and  63 touched each of the sweet roses as though trying to engrave（刻画） them on her 64 .
　　“How can I ever thank you” she said softly.
I was almost embarrassed. It was such a little    65  on my part.
