Who Want to Live Forever?
If your doctor could give you a drug that would let you live a healthy life for twice as long，would you take it?
The good news is that we may be drawing near to that date,Scientists have already extended the lives of flies,worms and mice in laboratories. Many now think that using genetic treatments we will soon be able to extend human life to at least 140 years.
This seems a great idea.Think of how much more time we could spend chasing our dreams，spending time with our loved ones，watching our families grow and have families of their own.
"Longer life would give us a chance to recover from our mistakes and promote long term thinking," says Dr Gregory Stock of the UniversityOfCalifornia School Of Public Health. "It would also raise productivity by adding to the year we can work."
Longer lives don"t just affect the people who live them. They also affect society as a whole. "We have war，poverty，all sorts of issues around，and I don"t think any of them would be at all helped by having people live longer,"says US bioethicist Daniel Callahan."The question is "What will we get as a society?"I suspect it won"t be a better society."
It would certainly be a very different society.People are already finding it more difficult to stay married.Divorce rates are rising.What would happen to marriage in a society where people lived for 140 years?And what would happen to family life if nine or 10 generations of the same family were all alive at the same time?
Research into ageing may enable women to remain fertile for longer. And that raises the prospect of having 100-year-old parents，or brothers and sisters born 50 years apart1. We think of an elder sibling as someone who can protect us and offer help and advice. That would be hard to do if that sibling came from a completely different generation.
Working life would also be affected，especially if the retirement age was lifted. More people would stay in work for longer. That would give us the benefits of age-skill，wisdom and good judgment.
On the other hand，more people working for longer would create greater competition for jobs. It would make it more difficult for younger people to find a job.Top posts would be dominated by the same few individuals，making career progress more difficult. And how easily would a 25-year-old employee be able to communicate with a 125-year-old boss?
Young people would be a smaller part of a society in which people lived to 140. It may be that such a society would place less importance on guiding and educating young people，and more on making life comfortable for the old.
And society would feel very different if more of its members were older. There would be more wisdom,but less energy. Young people like to move about. Old people like to sit still. Young people tend to act without thinking.Old people tend to think without acting.Young people are curious and like to experience different things.Old people are less enthusiastic about change. In fact,they are less enthusiastic about everything.
The effect of anti-ageing technology is deeper than we might think. But as the science advances，we need to think about these changes now.
" If this could ever happen，then we"d better ask what kind of society we want to get，" says Daniel Callahan. "We had better not go anywhere near it2 until we have figure those problems out."

Passage Four Internet-addicted job seekers may be partly the cause of the fact that it is taking the unemployed 23 % longer to find a new position than it took during the last recession (经济萧条), when the "benefits" of online job searching were unavailable. "A growing number of unemployed Americans waste time browsing (济览) the estimated 4,000 to 5,000 online job sites, filling them with resumes, and then waiting for replies. It is common for long-time jobless ness," argues Professor John A. Challenger. Although the Internet has the potential to be very useful for job seekers and it has become the primary tool for many, Challenger believes that it should be considered secondary to the traditional technique of meeting would-be employers in person. In addition to slowing job search efforts, the Internet is making the hiring process longer for the employer. In a survey of 5,000 hiring managers by an online resume site, 72 % said that a majority of the resumes they received in response to an online job posting did not match the position’s description. "The more unrelated resumes managers have to go through in order to select the few to bring in for interviews, the longer it takes to fill the position," points out Challenger. "One result of this has been the increased use of screening software by employers. This will make it even more difficult for job seekers to get their resumes in front of the hiring executive for an interview." "All of this is not to say that the Internet has not revolutionized job hunting. It has certainly made it easier for someone in San Francisco, for example, to search for job openings in Miami. In addition, the ability to conduct keyword searches has reduced the amount of time it takes to find the type of position a person is seeking." "Job seekers must learn how to use the Internet as a tool, rather than just relying on it as a means for submitting electronic resumes," concludes Challenger.
According to the passage, the coming of online job searching brings（）A:longer waiting time for the unemployed B:longer computer technology training for the job seekers C:more unemployment throughout the USA D:more job opportunities in the Internet world

High{{/B}} ? ?Life expectancy rates in the United States are at an all- time high, with people born in 2005 projected to live for nearly 78 years, a new federal study finds. ? ?The finding reflects a continuing trend of increasing life expectancy that began in 1955, when the average American lived to be 69.6 years old. By 1995, life expectancy was 75.8 years, and by 2005, it had risen to 77.9 years, according to the report released Wednesday. ? ?"This is good news," said report co - author Donna Hoyert, a health scientist at the National Center for Health Statistics. "It’s even better news that it is a continuation of trends, so it is a long period of continuing improvement.

The country with the longest life expectancy is Andorra at 83.5 years, followed by Japan, Macau, San Marino and Singapore. ? ?Much of the increase owes to declining death rates from the three leading causes of death in the country - heart disease, cancer and stroke. ? ?In addition, in 2005, the U.

But the evidence we have suggests that there is more chronic disease than ever in the U. S." ? ?Adding years to life is a good thing, Katz said. "But adding vital life to years is at least equally important. If we care about living well, and not just longer, we still have our work cut out for us," he said. |
