Cell Phones : Hang Up or Keep Talking?
Millions of people are using cell phones today.In many places it is actually considered unusual not to
use one.In many countries,cell phones are very popular with young people.They find that the phones are
more than a means of communication一having a mobile phone shows that they are cool and connected.
The explosions around the world in mobile phone use make some health professionals worried.Some
doctors are concerned that in the future many people may suffer health problems from the use of mobile
phones.In England,there has been a serious debate about this issue.Mobile phone companies are worried
about the negative publicity of such ideas.They say that there is no proof that mobile phones are bad for your
health.
On the other hand,why do some medical studies show changes in the brain cells of some people who use
mobile phones?Signs of change in the tissues of the brain and head can be detected with modern scanning
（扫描）equipment. In one case , a traveling salesman had to retire at a young age because of serious memory
Loss.He couldn't remember even simple tasks.He would often forget the name of his own son.This man used
to talk on his mobile phone for about six hours a day,every day of his working week,for a couple of years.
His family doctor blamed his mobile phone use,but his employer's doctor didn't agree.
What is it that makes mobile phones potentially harmful?The answer is radiation.High-tech machines

some radiation,but they say the amount is too small to worry about.

it.Mobile phones can be very useful and convenient,especially in emergencies.In the future,mobile phones
may have a warning label that says they are bad for your health.So for now,it's wise not to use your mobile
phone too often.

American Dreams
There is a common response to America among foreign writers:the US is a land of
extremes where the best of things are just as easily found as the worst.This is a cliché（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.________(1)No class system or government 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.________(2)
Over the past 25 years the median US family income has gone up 18 percent.For the
top 1 percent,however,it has gone up 200 percent.Twenty-five years ago the top fifth
of Americans had an average income 6.7 times that of the bottom fifth.________
(3)
Inequalities have grown worse in different regions.In California,incomes for lower
class families have fallen by 4 percent since 1969.________(4)This has led to an
economy hugely in favor of a small group of very rich Americans.The wealthiest 1 percent
of households now control a third of the national wealth.There are now 37 million
Americans living in poverty.At 12.7 percent of the population,it is the highest percentage
in the developed world.
Yet the tax burden on America's rich is falling,not growing.________(5)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.
________（3）
A:Nobody is poor in the US.
B:The top 0. 01 percent 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 percent.
D:Now it is9.8 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.

Women,Keep Dieting!
To most women who are trying to keep slim,dieting can seem to last a lifetime,or to be more exact,31 years,for researchers have found that is how long the average woman spends on a diet over the course of her life.
A university did a research on diet of British people for as long as 10 years,whose result revealed such a picture.British women spend averagely six months a year counting the calories and more than one fifth are on a permanent diet throughout their lifetime in a seemingly never-ending pursuing the perfect figure.
However,they aren't the only ones waging a constant fight against the loose fat. The average adult male spends 28 years losing weight,the poll has discovered.It found that over a tenth of the UK population is currently dieting in a bid to shed the pounds after feasting on festive treats over the Christmas period.Though holding the best intentions,three quarters of those who began their New Year with the firm resolution to lose weight give up by the end of the week.The average diet lasts 5.5 weeks,with the post-Christmas fast being even shorter at just three weeks.Half of slimmers throw in the towel due to lack of determination,while a quarter of interviewee answered that they give up because the strict diet regime makes them moody or depressed.The most determined dieters of all are aged from 45 to 64,almost a quarter spending up to a year slimming. In comparison,those aged between 18 and 24 are more likely to be yo-yo dieters,with a fifth giving up within a month.
The survey of 1,446 of men and women found that nearly two thirds of the UK population are unhappy with their body and feel that being thinner would make them happier.
For women,looks are more important,with over half reporting that they diet to wear fashionable clothes and a third of those surveyed said they watched their weight in a bid to feel more attractive. But in comparison,men are more focused on their long-term well-being,with over a third saying they wanted to lose weight to be more healthy.
Do female and male go on diet for the same reason?
A:She always makes sure to attend the big events in the life of her sons.
B:Women go on diet to look good while male to keep fit.
C:She always gives priority to work rather than to her family.
D:She seldom has time to take a holiday.
