American Dreams
There is a common response to America among foreign writers:the US is a land of extremes where the best of things qre just as easily found as the worst.This is a cliche(陈词滥调).
In the land of black and white,people should not be too surprised to find some of the biggest gaps between the rich and the poor in the world.But the American Dream offers a way out to everyone.(46) No class system or govemment stands in the way.
Sadly,this old argument is no longer true.Over the past few decades there has been a fundamental shift in the structure of the American economy.
The gap between the rich and the poor has widened and widened.(47)
Over the past 25 years the median US family income has gone up 18 per cent.For the top 1 per cent,however,it has gone up 200 per cent.Twenty-five years ago the top fifth of Americans had an average income 6.7 times that of the bottom fifth.(48)
Inequalities have grown worse in different regions.In California,incomes for lower class families have fallen by 4 per cent since 1969.(49) This has led to an economy hugely in favor of a small group of very rich Americans.The wealthiest 1 per cent of households now control a third of the national wealth.There are now 37 million Americans living in poverty.At 12.7 per cent of the population,it is the highest percentage in the developed world.
Yet the tax burden on America’s rich is falling,not growing.(50) There was an economic theory holding that the rich spending more would benefit everyone as a whole.But clearly that theory has not worked in reality.
A.Nobody is poor in the US.
B.The top 0.01 per cent of households has seen its tax bite fall by a full 25 percentage points since 1980.
C.For upper class families they have risen 41 per cent.
D.Now it is 9.8 times.
E.As it does so,the possibility to cross that gap gets smaller and smaller.
F.All one has to do is to work hard and climb the ladder towards the top.

High Stress May Damage Memory
According to a report issued in May 1998，elderly people who have consistently high b1ood levels of cortisol don’t score as well on memory tests as their peels with lower levels of the stress hormone．What’s more． high 1evels of cortisol are also associated with shrinking 0f the hippocampus，a region of the brain that plays a key role in learning and memory．The 6ndings suggest that even cortisol levels in the normal，“healthy” range can actually accelerate brain aging．
The study results “now provide substantial evidence that long—term exposure to adrenal stress hormones may promote hippocampal aging in normal elderly humans，”write Nada Porter and Philip Landfield of the University of Kentucky in Lexington in their editorial．Cortisol is a hormone released in response to stress by the adrenal glands，which sit on top of the kidneys．
Over a 5 to 6一year period，Dr． Sonia Lupien and his colleagues measured 24一hour cortisol levels in 51 healthy volunteers，most of Whom were in their 70s．
Despite wide variation in cortisol levels．the participants could be divided into three Subgroups：those whose cortisol progressively increased over time and was currently high（increasing／high）：those whose cortisol progressively increased over time and was currently moderate（increasing／moderate）；and subjects whose cortisol decreased，but Was currently moderate（decreasing／moderate）．
The researchers tested the volunteers’ memory on six people in the increasing／high category and five people in the decreasing／moderate group．The groups did not differ on tests of immediate memory，but the increasing／high cortisol group had other memory problems compared with those in the decreasing／moderate group．
The researchers also found that the total volume of the hippocampus in those in the increasing／high group was 14％ lower than those in the decreasing／moderate group，although there were no differences in 0ther brain regions．
The results suggest that brain aging Can be accelerated by levels of adrenal hormones that are not generally regarded as pathological and that variation within this normal range is related to variation in the rate of brain aging．”write Porter and Landfield．“This further suggests that chronic stress may accelerate the worsening of hippocampus．”
第 26 题 The part of the brain important for a person’s learning and memory is．
A．the cortisol．
B．the adrenal glands．
C．the stress hormones
D．the hippocampus．

Women’s fashion is now, some believe, at the turning point of similar magnitude, coinciding with the equally dramatic social transformation of the past several decades. The change has been slow: a century long move away from the padding, corseting, and decoration that made a woman into a kind of ornate bauble(小摆设) and displayed her family’s wealth, and toward the clean, sleek modern lines first introduced with the suffrage movement.
But the shift has accelerated in recent years, thanks to changes in the technology and business of fashion. The use by top designers of "weird, fabulous, unrecognizable synthetics," says Hollander "has ruined the status of certain fabrics, like linen, which has had a leveling effect for the sexes and for' the classes." And the emergence of chains like Club Monaco means that "forward looking style. is disseminated very fast and very cheaply," according to Valerie Steele, a historian and curator of "Shoes: A Lexicon of Style," an exhibition now on view at New York’s Fashion Institute of Technology. Such stores have succeeded, she believes, because "there’s substantial group of people with a sophisticated eye for design" who are eager for an affordable version of what was once thought to be "dog-whistle fashion," pitched so high that only a few would get it. Against that back-ground, the shoes at FIT look like fashion’s last gasp. The exhibit begins with the most symbolically loaded of women’s shoes: high heels, which Steele calls "a prime symbol of women’s sexual power over men."
That same defiance of feminine expectations is visible throughout the FIT show: in the boot, for instance, with its connotations of machismo and. military power, or the androgynous oxford, made girlisl with a big chunky heel. The show ends, fittingly, with the sneaker. No longer simply a downscale kid wear item, the big, brilliantly colored, high-tech sneaker has become one of the today’s most dramatic fashion statements, asserting street hip and futuristic velocity. Maybe shoes aren’t so indifferent to the changes in modem lives, after all.
The end of men’s lavish attention to fashion marks
A．great political and social changes.
B．aristocracy.
C．social ranks.
D．the great renunciation.
