Fifty volunteers were alphabetically divided into two equal groups. Group A to participate

in a 7-week exercise program, and Group B to avoid deliberate exercise of any sort during those 7 weeks. On the day before the exercise program began, all 50 men participated in a step-test. This consisted of stepping up and down on a 16-inch bench at 30 steps a minute for 5 minutes. One minute after completion of the step-test, a pulse rate of each subject was taken and recorded. This served as the pretest for the experiment. For the next 7 weeks, subjects in the experimental group (Group A) rode an exercycle for 15 minutes each day. The exercise schedule called for riders to ride relaxed during the first day's ride, merely holding on to the handle bars and foot pedals as the machine moved. Then, for the next 3 days, they rode relaxed for 50 seconds of each minute, and pushed, pulled, and pedaled actively for 10 seconds of each minute. The ration of active riding was increased every few days, so that by the third week it was haft of each minute, and by the seventh week the riders were performing 15 solid minutes of active riding.

At the end of the 7 weeks, the step-test was again given to both groups of subjects, and their pulses taken. The post exercise pulse rates of subjects in the experimental group were found to have decreased an average of 30 heart beats per minute, with the lowest decrease of 28 and the highest decrease of 46. The pulse rates of subjects in the control group (Group B) remained the same or changed no more than 4 beats, with an average difference between the initial and final tests of zero.

How many people were in each group？

A．100.

B．25.

C．50.

D．15.

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.
