Prolonging Human Life
Prolonging human life has increased the size of the human population.Many people alive to-day would have died of childhood diseases if they had 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 survived they could have another child.In most contempo- rary 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 under-skilled personnel.

The writer believes that the population explosion results from______.
A: an increase in birthrates
B: the industrial development
C: a decrease in death rates
D: cultural advances

Text 1 A new study suggests that contrary to most surveys,people are actually more stressed at home than at work.Researchers measured people’s cortisol,which is a stress marker,while they were at work and while they were at home and found it higher at what is supposed to be a place of refuge.“Further contradicting conventional wisdom,we found that women as well as men have lower levels of stress at work than at home”,writes one of the researchers,Sarah Damske.In fact women even say they feel better at work,she notes.“It is men,not women,who report being happier at home than at work.”Another surprise is that findings hold true for both those with children and without,but more so for nonparents.This is why people who work outside the home have better health.What the study doesn’t measure is whether people are still doing work when they’re at home,whether it is household work or work brought home from the office.For many men,the end of the workday is a time to kick back.For women who stay home,they never get to leave the office.And for women who work outside the home,they often are playing catch-up-with-household tasks.With the blurring of roles,and the fact that the home front lags well behind the workplace in making adjustments for working women,it’s not surprising that women are more stressed at home.But it’s not just a gender thing.At work,people pretty much know what they’re supposed to be doing:working,making money,doing the tasks they have to do in order to draw an income.The bargain is very pure:Employee puts in hours of physical or mental labor and employee draws out life-sustaining moola.On the home front,however,people have no such clarity.Rare is the household in which the division of labor is so clinically and methodically laid out.There are a lot of tasks to be done,there are inadequate rewards for most of them.Your home colleagues—your family—have no clear rewards for their labor;they need to be talked into it,or if they’re teenagers,threatened with complete removal of all electronic devices.Plus,they’re your family.You cannot fire your family.You never really get to go home from home.So it’s not surprising that people are more stressed at home.Not only are the tasks apparently infinite,the co-workers are much harder to motivate.
The home front differs from the workplace in that_____

A.home is hardly a cozier working environment
B.division of labor at home is seldom clearcut
C.household tasks are generally more motivating
D.family labor is often adequately rewarded

Cell Phones

I Believe it or not,cell phones have been around for over a quarter of a century.The first commercial
cell phone systemfl was developed by the Japancoc in I 979.But cell phones have changed a lot
since that
time.The early cell phones were big and heavy but they have developed into small and light palm-sized mod-
els.There have been huge (lcveloprnents in their functions,too;we have had call forwarding,text messaging,
answering services and hands-free use for years,but now there are countless new facilities,su,ch as instant ac-
cess to the Internet and receiving and sending photos.
2 Cell phones have become very common in our lives;recent statistics suggest as many as one in three
people cii the planet now have a cell phone,and most of them say they couldn't live without one.Cell phones
are used in every area of our lives and have become a necessary tool,used for essential arrangements,social
contact and business.They have made it easier to call for help on the highway.They have made it possible to
keep in touch with people"on the move”一when people are traveling.
3 Cell phones have made communication easier and have reduced the need for family arguments.We
can use cell phones to let our family know we'11 be late or if there’。a sudden change of tian or an emergen-
cy.Cell phones have eased the worries of millions of parents when their teenagers are out late,they can now
contact their children at any time.
4 This does not mean that cell phones are all good news.They have brought with them a number of
new headaches for their owners;it costs a lot to replace stolen phones,something that is becoming a frequent
occurrence,and have you ever seen such huge phone bills? More serious,however,is the potential health
problem they bring:there are fears that radiation from the phones may cause brain tumor（肿瘤）.This may be
a time bomb waiting to happen to younger people who have grown up with cell phones that they simply can't
live without!

Cell phones are common in our lives and have become_________.
A:a necessity
B:an emergency
C:a number of new hcadaches
D:family arguments
F:big and light palm-sized models
F:countless new facilities

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 survived 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.

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.
