Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
"I think we are knocking at the door of immortality(永生)," said Michael Zey, a Montclair State University business professor and author of two books on the future. "I think by 2075 we will see it and that’s a conservative estimate".
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology（纳米技术）make it likely that humans will live in the future beyond what has been possible in the past. "There is a great push so that people can live from 120 to 180 years," he said. "Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years."
However, many scientists who specialize in ageing are doubtful about it and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. "It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?" said Leonard Pooh, director of the University of Georgia Gerontology(老龄学) Center. "At present people who could get to that point are not in good health at all."

To forgive may be wonderful, but no one ever said it was easy. When someone has deeply hurt you, it can be extremely difficult to let go of your anger.
___1___ In??deed, research has shown that people who forgive report more energy, better appetite and better sleep patterns. “People who forgive show less anger and more hopefulness,” says Dr. Freder??ic Luskin, who wrote the book Forgive for Good.
So how do you start the healing? Try following these steps:
Calm yourself. Take a couple of breaths and think of some??thing that gives you pleasure: a beautiful scene in nature, someone you love.
Don’t wait for an apology. ___2___ Luskin says, “They may have wanted to hurt you or they just don’t see things the same way. So if you wait for people to apologize, you could be waiting a very long time.” Keep in mind that forgiveness does not necessarily mean coming to terms with the person who upsets you or forgiving his or her action after your quarrel.
___3___ Mentally going over your hurt gives power to the person who brought you pain. “Instead, learn to look for the love, beauty and kindness around you.” Luskin says.
___4___ If you attach great importance to that person, you may realize that he or she was acting out of ignorance, fear and even love. To gain others’ stand, you may want to write a letter to yourself from your offender’s point of view.
___5___ Research has shown that people who forgive make a good show of more energy, better appetite and better sleeping patterns.
Don’t forget to forgive yourself. “For some people, forgiving themselves is the biggest challenge." Luskin says, “but it can rob you of your self-confidence if you don’t do it.”
A. Many times the person who hurt you may never think of apologizing.
B. Break away from the influence of your offender on you early.
C. But forgiveness is possible —and it can be surprisingly helpful to your physical and mental health.
D. Try to see things from the other person’s stand.
E. So it is difficult to forgive others and even yourself.
F. Recognize the benefits of forgiveness.
G. Forgiveness is not good of people.
查看习题详情和答案>>Do you sometimes argue about what seems to you to be a simple fact ? Do you argue whether it’s cold outdoors or whether the car in front of you is going faster than the speed limit ?
If you get into such arguments, try to think about the story about the six blind men and the elephant．The first blind man who felt the elephant’s trunk said it was like a snake．The second who felt the elephant’s side said it was like a wall, while the third said it was like a spear as he touched the animal’s tusk．The fourth, who had hold of the elephant’s tail insisted that it was like a rope．The fifth man said it looked like a tree as he put his arm around one the elephant’s legs.
The sixth, who was tall and got hold of the elephant’s ears, said it was like a huge fan.
Each man’s idea of the animal came from his own experience．So if someone disagrees with you about a “simple fact”, it’s often because his experience in the matter is different from yours.
To see how hard it is for even one person to make up his mind about a “simple fact”, try this simple experiment．Get three large bowls．Put ice water in one．Put hot water in the second．Put lukewarm water in the third．Now put your left hand in the ice water．Put your right hand in the hot water．After thirty seconds, put both hands in the lukewarm water．Your right hand will tell you the water is cold．Your left hand will tell you it’s hot !
What makes people think about simple facts differently ?
A．The fact that simple facts differ from one another
B．The fact that people have different experience in the same simple fact
C．The fact that people often disagree with one another
D．The fact that it’s hard to make up one’s mind about simple facts
The writer’s advice is _______________.
A．We should never think about simple facts
B．We should never judge something with a one-sided view
C．We should not agree about simple facts
D．We must learn from the six blind men
After reading the last paragraph, we may think of __________.
A．Newton’s law B．Galileo’s theory of falling objects
C．Einstein’s theory of relativity D．Marx’s On Capital (资本)

My husband and I got married in 1965 and for the first ten years of our marriage I was very happy to stay home and raise our three children. Then four years ago, our youngest child went to school and I thought I might go back to work.
My husband was very supportive and helped me to make my decision. He emphasized all of the things I can do around the house, and said he thought I could be a great success in business.
After several weeks of job-hunting I found my present job, which is working for a small public relations firm. At first, my husband was very proud of me and would tell his friends , "My clever little wife can run that company she's working for."
But as his joking remark approached reality, my husband stopped talking to me about my job．I have received several promotions and pay increases , and I am now making more money than he is. I can buy my own clothes and a new car. Because of our combined incomes, my husband and I can do many things that we had always dreamed of doing , but we don't do these things because he is very unhappy.
We fight about little things and my husband is very critical of me in front of our friends. For the first time in our marriage, I think there is a possibility that our marriage may come to an end．
I love my husband very much, and I don't want him to feel inferior, but I also love my job．I think I can be a good wife and a working woman, but I don't know how .Can you give me some advice? Will I have to choose one or the other or can I keep both my husband and my new career?
Please help.
