A monopolistically competitive market is characterized by barriers to entry

The cohesiveness(内聚力)of a family seems to rely on members sharing certain routine practices 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 research 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, including 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 characterized by a very clear division of roles: husbands are "providers" whose major responsibility is to support the family; wives are "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 speaking, when 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 at work, I want my wife to realize what I expect at work. I don't want her to give me a lot of shit when 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.

Despite______,shift work couples still hoped to maintain a stable life.

A．traditional beliefs about marriage

B．lack of control over time

C．a very clear division of roles

D．the demands of work

Washington Irving was America's first man of letters to be known internationally. His works were received enthusiastically both in England and in the United States. He was, in fact, one of the most successful writers of his time in either country, delighting a large general public and at the same time winning the admiration of fellow writers like Scott in Britain and Poe and Hawthorne in the United States. The respect in which he was held was partly owing to the man himself, with his warm friendliness, his good sense, his politeness, his gay spirits, his artistic integrity, his love of both the Old World and the New World. Thackery described Irving as"a gentleman, who, though himself born in no very high sphere, was most finished, polished, witty; socially the equal of the most refined Europeans". In England he was granted an honorary degree from Oxford—an unusual honor for a citizen of a young, uncultured nation—and he received the medal of the Royal Society of Literature; America made him ambassador to Spain. Irving's background provides little to explain his literary achievements. A gifted but delicate child, he had little schooling. He studied law, but without zeal, and never did practice seriously. He was immune to his strict Presbyterian(长老会教徒的)home environment, frequenting both social gatherings and the theater.

What is the most proper comment on Irving?

A．His works were very popular in England and the United States.

B．He was respected by many fellow writers.

C．He gained international fame by his personality and his works.

D．He is a gentleman.
