[单项选择]Theme-park-bound bargain seekers would be wise to spend some time surfing online before they get in line at the parks this summer.
A growing number of these attractions now allow customers to print e-tickets at home with large discounts off the gate price, in part to spur attendance that has declined in recent years.
After boom times in the late 1990s, theme park attendance began to decrease, with an overall decline of about 4% over the past few years at North America’’s 50 most-visited establishments, says James Zoltak, editor of Amusement Business. "The bloom was off the rose as we turned the corner into 2000, so there’’s more discounting now," he says.
Discounting isn’’t new to an industry that has long partnered with other commercial enterprises, such as soft drink companies, to offer deals. But e-ticketing adds a new opportunity that not only brings savings but convenience as well, since it allows visitors to avoid the line at the gate.
"If you can get in early

[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, traveling to and from work. What we do there largely determines our standard of living and the status we are accorded to a considerable extent 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 boredom, frustrations and humiliations by concentrating their hopes in the other parts of their lives. I reject that as a counsel of despair. For the foreseeable 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 work is done; only for
A. A reduction in the number of strikes.
B. Equality in salaries.
C. A more equal distribution of responsibility.
D. An improvement in moral standards.
