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.
ANobody is poor in the US.
BThe top 0.01 per cent of households has seen its tax bite fall by a full 25 percentage points since 1980.
CFor upper class families they have risen 41 per cent.
DNow it is 9.8 times.
EAs it does so,the possibility to cross that gap gets smaller and smaller.
FAll one has to do is to work hard and climb the ladder towards the top.

Robots May Allow Surgery in Space
Small robots designed by University of Nebraska researchers may allow doctors on Earth to help perform surgery on patients in space.
The tiny,wheeled robots,(51)are about 3 inches tall and as wide as a lipstick case,can be slipped into small incisions(切口)and computer-controlled by surgeons in different locations.Some robots are equipped(52)cameras and lights and can send images back to surgeons and others have surgical tools attached that can be(53)remotely.
“We think this is going to (54)open surgery,”Dr Dmitry Oleynikov said at a news conference.Oleynikov is a (55)in computer-assisted surgery at the University of Nebraska Medical Center in Omaha.
Officials hope that NASA will teach(56)to use the robots soon enough so that surgeries could one day be performed in space.
On earth,the surgeons could control the robots themselves(57)other locations.For example,the robots could enable surgeons in other places to (58)on injured soldiers on the front line.Researchers plan tp seek federal regulatory(59)early nest year.Tests on animals have been successful,and tests on humans in England will begin very soon.
The camera-carrying robots can provide(60)of affected areas and the ones with surgical tools will be able to maneuver(操控)inside the body in ways surgeons’ hands can’t.The views from the camera-carrying robots are (61)than the naked eye,because they(62)back color images that are magnified(放大).Because several robots can be inserted through one incision,they could reduce the amount and (63)of cuts needed for surgery,which would decrease recovery time.This is particularly(64)to those patients who have been debilitated(使虚弱)by long illness.
Eventually,Oleynikov said,the tiny robots may enable surgeons to work without ever(65)their hands in patients’ bodies.“That’s the goal,”Oleynikov said.“It’s getting easier and easier.We can do even more with these devices.”
