Are You Getting Enough Sleep?
What happens if you don't get enough sleep? Randy Gardner,a high school student in the United
States,wanted to find out. He designed an experiment on the effects of sleeplessness for a school science
project. With doctors watching him carefully,Gardner stayed awake for 264 hours and 12 minutes.That's
eleven days and nights without sleep!
What effect did sleeplessness have on Gardner? After 24 hours without sleep,Gardner started having
trouble reading and watching television. The words and pictures were too blurry（模糊）.By the third day,
he was having trouble doing things with
his hands. By the fourth day, Gardner was hallucinating（产生幻
觉）.For example,when he saw a street sign,he thought it was a person.He also imagined he was a famous
football player. Over the next few days, Gardner's speech became so slurred（不清楚）that people couldn't
understand him.He also had trouble remembering things.By the eleventh day, Gardner couldn't pass a
counting test.In the middle of the test he simply stopped counting.He couldn't remember what he
was doing.
When Gardner finally went to bed,he slept for 14 hours and 45 minutes.The second night he slept for
twelve hours,the third night he slept for ten and one-half hours,and by the fourth night,he had returned to
his normal sleep schedule.
Even though Gardner recovered quickly,scientists believe that going without sleep can be dangerous.
They say that people should not repeat Randy's experiment. Tests on white rats have shown how serious
sleeplessness can be. After a few weeks without sleep, the rats started losing their fur（皮毛）.And even
though the rats ate more food than usual,they lost weight.Eventually the rats died.
During your lifetime,you will probably spend 25 years or more sleeping.But why?What is the purpose
of sleep? Surprisingly,scientists don't know for sure.Some scientists think we sleep in order to
replenish（补充）brain cells. Other scientists think that sleep helps the body to grow and to relieve stress.
Whatever the reason,we know that it is important to get enough sleep.
Randy Gardner studied the effects of over-sleeping.
A:Right
B:Wrong
C:Not mentioned

Prolonging Human Life
Prolonging human life has increased the size of the human population.Many people alive today would have died of childhood diseases if they been born 100 years ago. Because more people live longer,there are more people around at any given time.in fact,it is a decrease in death rates,not an increase in birthrates, that has led to the population explosion.
Prolonging human life has also increased the dependency load.In all societies,people who are disabled or too young or too old to work are dependent on the rest of society to provide for them.In hunting and gathering cultures,old people who could not keep up might be left behind to die.In times of famine,infants might be allowed to die because they could not survive if their parents starved,whereas if the parents sur- vived they could have another child.In most contemporary societies,people feel a moral obligation to keep people alive whether they can work or not.We have a great many people today who live past the age at which they want to work or are able to work;we also have rules which require people to retire at a certain age.Unless these people were able to save money for their retirement,somebody else must support them.In the United States many retired people live on social security checks which are so little that they must live in near poverty.Older people have more illness than young or middle-aged people;unless they have wealth or private or government insurance,they must often"go on welfare"if they have a serious illness.
When older people become senile or too weak and ill to care for themselves,they create grave problems for their families.In the past and in some traditional cultures,they would be cared for at home until they died.Today,with most members of a household working or in school,there is often no one at home who can care for a sick or weak person.To meet this need,a great many nursing homes and convalescent hospitals have been built.These are often profit-making organizations,although some are sponsored by religious and other nonprofit groups.While a few of these institutions are good,most of them are simply"dumping grounds"for the dying in which"care"is given by poorly paid,overworked,and underskilled personnel.
According to the passage,which of the following statements about retired people in the United States is true?
A:Many of them have a very hard life.
B:They cannot live a decent life without enough bank savings.
C:They rely mainly on their children for financial support.
D:Most of them live with their children and therefore are well looked after.

Free Statins with Fast Food could Neutralize Heart Risk
Fast food outlets could provide statin drugs free of___1___so that customers can reduce the heart disease dangers of fatty food,researchers at Imperial College London ___2___in a new study.
Statins reduce the___3___of unhealthy“LDL” cholesterol in the blood. A wealth of trial data has proven them to be highly effective at lowering a person's heart attack___4___.
In a paper published in the American Journal of Cardiology,Dr Darrel Francis and col-leagues calculate that the reduction in heart attack risk offered by a statin is___5___to offset the increase in heart attack risk from___6___a cheeseburger and drinking a milkshake.
Dr Francis,from the National Heart and Lung Institute at Imperial College London,who is the senior author of the study,said:“Statins don't cut out all of the ___7___effects of cheeseburgers and French fries. It's better to avoid fatty food altogether. But we've worked out that in terms of your___8___of having a heart attack. Taking a statin can reduce your risk to more or less the same___9___as a fast food meal increases it.”“It's ironic that people are free to take as many unhealthy condiments in fast food outlets as they___10___，but statins,which are beneficial to heart health,have to be prescribed. It makes sense to make risk-reducing st- atins available just as easily as the unhealthy condiments that are___ 11___free of charge.
