问题补充：

America is growing older. Fifty years ago, only 4 out of every 100 people in the United States were 65 or older. Today, 10 out of every 100 Americans are over 65. The aging of the population will affect （影响） American society in many ways --- education, medicine, and business. Quietly, the graying of America has made us a very different society - one in which people have a quite different idea of what kind of behavior （行为）is suitable （合适） at different ages.

A person’s age no longer tells you anything about his/her social position, marriage or health. There’s no longer a particular year in which one goes to school or goes to work or gets married or starts a family. The social clock that kept us on time and told us when to go to school, get a job, or stop working isn’t as strong as it used to be. It doesn’t surprise us to hear of a 29-year-old university president or a 35-year-old grandmother, or a 70-year-old man who has become a father for the first time. Public ideas are changing.

Many people say, ‘I am much younger than my mother - or my father - was at my age.’ No one says ‘Act your age’ anymore. We’ve stopped looking with surprise at older people who act in youthful ways.

答案：

(答案→)C

解析：

本文主要讲述美国社会老龄化这一事实以及这一变化对人们的行为、思想等各方面都产生了极大的影响，其中第一、二段的最后一句话尤为重要。

1. C 主旨题。根据第一、二段的最后一句及第三段可判断。

2. A 细节题。one是a society的同位语且后面跟了一个定语从句，可以通过分析句子结构得出正确答案。

3. B 细节题。全文最后一句话给出了提示。

4. A 推理题。可仔细阅读第二段中倒数第二句话。

5. A根据It doesn’t surprise us to hear of a 29-year-old university president or a 35-year-old grandmother…可知作者对此不感到惊奇，也就是说觉得很普通，选A。
