[单项选择]A new era is upon us. Call it what you will: the service economy, the information age, the knowledge society. It is all translated to a fundamental change in the way we work. Already we’ve partly been there. The percentage of people who earn their living by making things has fallen dramatically in the Western World. Today the majority of jobs in America, Europe and Japan (two thirds or more in many or these countries) are in the service industry, and the number is on the rise. More women are in the work force than ever before. There are more part-time jobs. More people are self-employed. But the breadth of the economic transformation can’t be measured by numbers alone, because it is also giving rise to a radical new way of thinking about the nature of work itself. Long-held notions about jobs and careers, the skills needed to succeed, even the relation between individuals and employers—all these are being changed.
We have only to look behind us to get some sense of what may lie ah

Passage Two
Parents have to do much less for their children than they used to do, and home has become much less of a workshop. Clothes can be bought ready made; washing can be done at the laundry; food can be bought cooked, canned; bread is baked and delivered by the baker; milk arrives on the doorstep; meal can be had at the restaurant, the work’s canteen, and the school dining room.
It’s unusual now for father to persue (追求)his trade of other employment at home, and his children rarely, if ever, see him at his place of work.
