America is growing older. Fifty - eight

题型:阅读理解

问题:

America is growing older. Fifty - eight years ago, only 4 out of every 100 people in the United States were 65 or older. To day, 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 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 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” any more. We’ve stopped looking with surprise at older people who act in youthful ways.

《能源效率标识管理办法》规定,能效五级是最低的能效标准,是产品上市的最低要求,低于这个要求不许生产销售。而节能标识和能效标识是两个不同的概念。目前,节能空调和节能冰箱的认证标准是能效二级,所有的节能产品必须达到二级能效标准以上。但这也并不是说所有标有二级或一级能效标识的产品就是节能产品,这样的产品只有再经过认证才能决定是否属于节能产品。 根据以上信息,能够推出以下哪项结论

A.所有贴有能效标识的产品都是节能产品。

B.节能产品肯定标有二级或一级标识。

C.达到二级能效标准就可以认为是节能产品了。

D.能效五级的产品是质量合格的产品,也是节能产品。
