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.

I expect him to be a good provider and 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.

1.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 workers were NOT satisfied with

2.From the selection, we can conclude that female shift workers were NOT satisfied with ().

A.their work

B.their children

C.their husbands’ inability to protect the family and provide companionship

D.leisure activities

3.What is implied by the author？()

A.Shift work had a direct effect on the attitudes and behavior. of family members

B.Shift workers could live a normal life

C.Shift work couples had unconventional ideas about marriage

D.Female shift workers were satisfied with the time spent together with their families

4.In order to continue the marriages of the shift workers, ().

A.wives must learn to care for the children when their husbands are absent

B.shift work couples must administer their time and activities

C.wives mustn’t adapt their own feelings of boredom to their husbands’ work

D.all of these

but they just pass their exams, while some others may spend much less time on their books but do much better in exams. How could this happen？ People used to think that hard work is the only way to success. But now they have understood that smart work can make them succeed too. Hard workers don’t mind working for long hours, while smart workers always think of several different answers to these questions, such as “Why should I suffer this？ ” or “Isn’t there a way to do this？ ” Thanks to these people, we can use computers instead of the abacus now. progress in every field is the direct result of “trying to find a better way ” by smart workers. There was a large soap factory in Japan. Once it received an unusual letter from someone who complained that there was no soap in the soap in the soapbox he bought.How could empty soapboxes go out of the factory？ The engineers checked the producing and packing. The producing was fine, but in about ten thousand soapboxes, the packing machine let an empty soapbox go. There was no need to spend a lot of money repairing the machine for such a small problem. The engineer soon worked out a solution. He put a huge X-ray machine and two large computers to find out the empty soapboxes. After teaching the workers how to use it, he sat down in his seat, exhausted.

“Sir, we could have solved the problem in a much simpler and cheaper way, ” a worker sa id.

“Really？ How？”

“We can put a huge fan near the packing machine. The wind coming from the fan will blow away the empty boxes, leaving the other boxes with soap. ”

See, this is smart work. In order to succeed, we should not only work hard like the engineer, but also think smart like this worker.

1. Some students spend less time on school work but do better in exams because they study longer.

A: F

B: T

2.The passage mainly tells us we should work hard like the engineer and think smart like theworker.

A: T

B: F

3.The soap factory could only put a huge fan near the packing machine to solve problem in amuch simpler and cheaper way.

A: F

B: T

4.The underlined phrase “blow away”means “停止” in Chinese.

A: T

B: F

5.Someone wrote to the soap factory and complained that the soapbox he bought was terrible.

Mass production, the defining characteristic of the Second Wave economy, becomes increasingly obsolete as firms install information intensive, often robotized manufacturing systems capable of endless cheap variation, even customization. The revolutionary result is, in effect, the demassification of mass production.

The shift toward smart flex techs promotes diversity and feeds consumer choice to the point that a Wal-Mart store can offer the buyer nearly 110,000 products in various types, sizes, models and colors to choose among. But Wal-Mart is a mass merchandiser. Increasingly, the mass market itself is breaking up into differentiated niches as customer needs diverge and better information makes it possible for businesses to identify and serve micro markets.

Specialty stores, boutiques, superstores, TV home-shopping systems, computer based buying, direct mail and other systems provide a growing diversity of channels through which producers can distribute their wares to customers in an increasingly demassified marketplace. When we wrote Future Shock in the late 1960s, visionary marketers began talking about "market segmentation". Today they no longer focus on " segments" but on " particles "—family units and even single individuals. Meanwhile, advertising is targeted at smaller and smaller market segments reached through increasingly demassified media.

The dramatic breakup of mass audiences is underscored by the crisis of the once great TV networks, ABC, CBS, and NBC, at a time when Tele-Communications, Inc. of Denver, announces a fiber optic network capable of providing viewers with five hundred interactive channels of television. Such systems mean that sellers will be able to target buyers with even greater precision. The simultaneous demassification of production, distribution and communication revolutionizes the economy and shifts it from homogeneity toward extreme heterogeneity.

Which is true about "mass production" according to the author？

A．It promotes further development in manufacturing systems.

B．It defines the Second Wave economy and will last.

C．It involves intensive information, automation, and customization.

D．It is becoming dated for the present economy.
