     People like to say: "The hand that rocks (摇动) the cradle (摇篮) rules the world." Or they say: "Behind
every successful man, there is a woman." Now some women still like making their husbands and sons
successful. But some women want more for themselves. They want to be successful as men. Today the
best jobs are still given to men. Even when women do the same work, they are often paid less than men.
Some women want these things changed. They want to stand beside the men, with the same chances for
success. Now many American women are earning money outside their homes. More than half of the women
at the age of eighteen to sixty-five have good jobs. In general, working women have more education than
those who stay at home. Among women with jobs, eight out of ten drive a car to work, and most of them
often spend their holidays away from home. They like traveling by air. Women's work had made several
changes in women's lives and in men's lives, too. But things are quite different from those in the Middle East
countries. In the Middle East countries, women have to stay at home. Their duty is to look after their families
and do all the housework. They can't find work outside. When they go out in public, they cover their faces
with something and walk behind their husbands. For the past few years the women's life has been changing in
those countries. Many women want to play an active role in the society (社会). Though working gives them
few chances of getting married, many men still want to marry them in the old ways.
