【单选题】

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 pursue(追求)his trade of other employment at home, and his children rarely, if ever, see him at his place of work.Boys are therefore seldom trained to follow their father’s business, and in many towns they have a fairly wide choice of employment and so do girls. The young wage-earner often earns good money, and soon gains a feeling Of economic independence (经济上的独立). In textile areas it has been customary for mothers to go out to work, but this practice has become so widespread that the working mother is now not an unusual factor in a child’s home life, the number of married women in employment having more than doubled in the last twenty- five years. With mother earning and older children drawing wages, father is seldom the most important figure that he still was at the beginning of the century. When mother works, economic advantages increase, but children lose something of great value if mother’s employment prevents her from being home to greet them when they return from school.
It is implied in the passage that______.A．mothers have the practice to go to work
B．working mothers have no time to stay with their children at home
C．mother’s position in a family has been raised
D．young wage-earners are economically independent
