阅读短文，回答题．The cohesiveness(内聚力 ) of a family seems to rely on members sharing certain routine prac- tices and events. For a growing share of the American labor force, however, working shifts beyond the normal daylight hours--what we here call "shift work"--makes the lives of families difficult.
Existing re.search shows that both male and female shift workers express high levels of stress and a sense of conflict between the demands of work and family life. But shift work couples still maintain a traditional attitude to the meaning of marriage and the individual roles of husband and wife. They expressed a willingness to do "whatever it takes" to approximate their view of a proper marriage,in- cluding sacrificing sleep and doing conventional things at unconventional hours. For the majority of couples interviewed, even when wives worked outside their homes, a proper marriage is character- ized by a very clear division of roles: husbands are "providers" whose major responsibility is to sup- port the family ;wives arc "homemakers" who clean, cook, and care for husbands and children.
The women's definitions of a "good husband" are typified by the following wife's response:
I expect him to be a good provider, and be there when I need him, loyal about the same things as he would expect out of me,expect that I expect him to dominate over me. But in a manner of speak- ing, wben it' s time to be a man I expect him to stand up instead of sitting back expecting me to do everything.To husbands,a good wife is someone who is:
Understanding of what I feel go through at work. I need that respect at work,I hope I get it al work. I want my wife to realize what I expect at work. I don' t want her to give me a lot of shilwhen I come home from work because I don' t know if this makes much sense.
These views seemed critical to maintain the families of the shift workers.
