When lab rats sleep, their brains revisit the maze they navigated during the day, according to a new study (1)_____ yesterday, offering some of the strongest evidence (2)_____ that animals do indeed dream. Experiments with sleeping rats found that cells in the animals' brains fire in a distinctive pat tern (3)_____ the pattern that occurs when they are (4)_____ and trying to learn their way around a maze.

Based on the results, the researchers concluded the rats were dreaming about the maze, (5)_____ re viewing what they had learned while awake to (6)_____ the memories.

Researchers have long known that animals go (7)_____ the same types of sleep phases that people do, including rapid-eye-movement (REM) sleep, which is when people dream. But (8)_____ the occasional twitching, growling or barking that any dog owner has (9)_____ in his or her sleeping pet, there's been (10)_____ direct evidence that animals (11)_____. If animals dream, it suggests they might have more (12)_____ mental functions than had been (13)_____.

"We have as humans felt that this (14)_____ of memory—our ability to recall sequences of experiences—was something that was (15)_____ human," Wilson said. "The fact that we see this in rodents (16)_____ suggest they can evaluate their experience in a significant way. Animals may be (17)_____ about more than we had previously considered."

The findings also provide new support for a leading theory for (18)_____ humans sleep—to solidify new learning. "People are now really nailing down the fact that the brain during sleep is (19)_____ its activity at least for the time immediately before sleep and almost undoubtedly using that review to (20)_____ or integrate those memories into more usable forms," said an assistant professor of psychiatry at Harvard Medical School.

Living standards soared during the twentieth century, and economists expect them to continue rising in the decades ahead. Does that mean that we humans can look forward to increasing happiness?

Easterlin admits that richer people are more likely to report themselves as being happier than poorer people are. But steady improvements in the American economy have not been accompanied by steady increases in people's self-assessments of their own happiness. "There has been not improvement in average happiness in the United States over almost a half century—a period in which real GDP (gross domestic product) per capital more than doubled," Easterlin reports.

The explanation for this paradox may be that people become less satisfied over time with a given level of income. In Easterlin's word: "As incomes rise, the aspiration level does too, and the effect of this increase in aspirations is to invalidate the expected growth in happiness due to higher income."

Money can buy happiness, Easterlin seems to be saying, but only if one's amounts get bigger and other people aren't getting more. His analysis helps to explain sociologist Lee Rainwater's finding that Americans' perception of the income "necessary to get along" rose between 1950 and 1986 in the same proportion as actual per capital income. We feel rich if we have more than our neighbors, poor if we have less, and feeling relatively well off is equated with being happy.

Easterlin's findings challenge psychologist Abraham Maslow's "hierarchy of wants" as a reliable guide to future human motivation. Maslow suggested that as people's basic material wants are satisfied they seek to achieve nonmaterial or spiritual goals. But Easterlin's evidence points to the persistence of materialism.

Science has developed no cure for envy, so our wealth boosts our happiness only briefly while shrinking that of our neighbors. Thus the outlook for the future is gloomy in Easterlin's view:

"The future, then, to which the era of modem economic growth is leading is one of never ending economic growth, a world in which ever growing abundance is matched by ever rising aspirations, a world in which cultural difference is leveled in the constant race to achieve the good life of material plenty, it is a world founded on belief in science and the power of rational inquiry and in the ultimate capacity of humanity to shape its own destiny. The irony is that in this last respect the lesson of history appears to be otherwise: that there is no choice. In the end, it is not the triumph of humanity over material wants; rather, it is the triumph of material wants over humanity."

Easterlin seems to suggest that

A．the richer people become, the happier they feel.

B．people feel unhappy just because they are not rich enough.

C．the increase of wealth certainly results in the increase of happiness.

D．the increase of wealth does not necessarily result in the increase of happiness.
