单选题It was possible to define male and female roles easily by the division of labour. Men worked outside the home and earned the income to raise their families, while women cooked the meals and there was not much opportunity for men or women to exchange their roles. But by the middle of this century, men's and women's roles were becoming less firmly fixed. In the 1950s, economic and social success was the aim of the typical American. But in the 1960s a new force called the counterculture developed. The people involved in this movement did not value the middle-class American goals. The counterculture presented men and women with new role choices. Taking more interest in child care, men began to share child-raising tasks with their wives. Actually some young men and women moved to communal homes or farms where the economic and child care responsibilities were shared equally by both sexes. In addition, many Americans did not value the traditional male role of soldier. Some young men refused to be drafted as soldiers to fight in the war in Vietnam. In terms of numbers, the counterculture was not a very large group of people. But its influence spread to many parts of American society. Working men of all classes began to change their economic and social patterns. Industrial workers and business executives alike cut down on "over- time" work so that they could spend more leisure time with their families. Some doctors, lawyers, and teachers turned away from high paying situations to practice their professions in poorer neighborhoods. In the 1970s, the feminist movement, or women's liberation, produced additional economic and social changes. Women of all ages and at all levels of society were entering the work force in greater numbers. Most of them still took traditional women's jobs such as public school teaching, nursing, and secretarial work. But some women began to enter traditionally male occupations: police work, banking, dentistry, and construction work. Women were asking for equal work, and equal opportunities for promotion. Today the experts generally agree that important changes are taking place in the roles of men and women. Naturally, there are difficulties in adjusting to these changes.

单选题If you're relying on Grandma to help with child care, it's time to reconsider. A new study of more than 54 000 women found that those who watched their grandkids 9 hours a week or more were 55% more likely to have a heart attack. These women may have less time to take care of their own health, says lead author Sunmin Lee, ScD, of the Harvard School of Public Health. Younger kids may pose more risk because they need more care. "However willing your mom might seem, it's up to you to figure out how much she can really handle," says Meredith Minkler, DrPH, a public-health professor at the University of California, Berkeley, and an expert on grandparents as caregivers. "It's not just about physical health. Older adults need time to connect with people of their own age. Social isolation is a major risk factor for illness." If your mom helps out, make sure she has breaks during the day, as well as "vacations" at regular intervals.
