Question

请英语高手帮忙一下吧，谢谢啦

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 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 is suitable at various 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 doesnˊt 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 notions 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. Weˊve stopped looking with surprise at older
people who act in youthful ways.

Answer 1

CAABD 阅读比较复杂就不解释了
CC 第一题 通过The computer doesn’t work well，说明电脑不能很好地运行，暗示这电脑肯定是出什么问题了。所以选择must have done 一定是做了某事 B、should have gone =D、ought to have gone 本应该做某事而事实上却没有做某事
第二题，通过Mr. Edward was not in，主人不在，所以他的弟弟或哥哥act as （充当）起主人，来招呼客人 A、actor演员 B、guest 客人 C、host 主人 D、ghost 鬼
明白了么？
