[单项选择]For most of us, work is the central, dominating fact of life. We spend more than half our conscious hours at work, preparing for work, travelling to and from work. What we do there largely determines our standard of living and to a considerable extent the status we are accorded by our fellow citizens as well. It is sometimes said that because leisure has become more important the indignities and injustices of work can be pushed into a corner; that because most work is pretty intolerable, the people who do it should compensate for its boredoms, frustrations and humiliations by concentrating their hopes on the other parts of their lives. I reject that as a counsel of despair. For the forseeable future the material and psychological rewards which work can provide, and the conditions in which work is done, will continue to play a vital part in determining the satisfaction that life can offer. Yet only a small minority can control the pace at which they work or the conditions in which their

[单项选择] Egyptian society had a strictly organized class structure. The majority of people consisted of farmers and craftsmen who were led by the land-owning elite (精英) of officials and priests. Everyone belonged to a group and worked in a team, usually in huge workshops, or "Storehouses", which were controlled by the king and the temples.
