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 61 65. The aging of the population will affect American society in many ways—education, medicine, 62 (busy). 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 63 (suit) at various ages. A person’s age no longer tells you anything about his/her position, 64 (marry) or health. There’s no longer a particular year 65 one goes to school or goes to work or gets married or starts a
family. The social clock that 66 (keep) us on time and told us when to go to school, get a job, or stop working isn’t as strong as used 67 (be). It doesn’t surprise us to hear of a 25-year-old university president or a 35-year-old grandmother, or 68 80-year-old man who has become a father for the first time. Public ideas are changing. Many people say, “I am much 69 (young) than my mother—or my father—was at my age.” No one says “Act your age” any more. We’ve stopped 70 (look) with surprise at older people who act in youthful ways.
【回答】
考查介词，根据前文fifty years ago的情况判断现在10分之一的美国人超过65岁，over 超过。
ness 考查名词。根据前文的deucation，medicine判断此处用busy的名词形式business商业。
able 考查形容词。此处缺少表语，应用suit的形容词形式。
64. marriage 考查名词。根据空前后的position和health判断填marry的名词形式marriage。
考查定语从句。空后的定语从句中缺少时间状语，故填when。
考查时态。题干中后文有told，并列的谓语动词也应用过去式。
be 考查不定式。used to be过去常常是。
考查冠词。80eighty是以元音音素开头的单词，故用冠词an。
ger 考查比较级。根据空后的than判断填younger。
70. looking 考查动名词。stop doing sth停止正在做的事情。
