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(納米技術) 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 aging 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 Poon, director of the University of Georgia Gerontology Center. “ At present people who could get to that point are not in good health at all.”

1.By saying “ we are knocking at the door immortality”, Michael Zey means_____.

   A. they believe that there is no limit of living

   B. they are sure to find the truth about long living

   C. they have got some ideas about living forever

   D. they are able to make people live past the present life span

2.Donald Louria’s attitude toward long living is that_____.

   A. people can live from 120 to 180

   B. it is still doubtful how long humans can live

   C. the human body is designed to last about 120 years

   D. it is possible for humans to live longer in the future

3.70. The underlined “ it” (Para. 4) refers to_____.

   A. a great push                                               

B. the idea of living beyond the present life span

   C. the idea of living from 200 to 300                   

D. the conservative estimate

4.What would be the best title for this text?

   A. Living longer or not

   B. Science, technology and long living

   C. No limit for human life

   D. Healthy lifestyle and long living.

Is there a magic cutoff period when offspring become accountable for their own actions? Is there a wonderful moment when parents can become spectators (旁觀者) in the lives of their children and shrug, "It' s their life," and feel nothing?

When I was in my twenties, I stood in a hospital corridor waiting for doctors to put a few stitches in my son' s head. I was asked, "When do you stop worrying?" A nurse said, "When they get out of the accident stage." My mother just smiled faintly and said nothing.

When I was in my thirties, I sat on a little chair in a classroom and heard how one of my children talked incessantly, disrupted (打斷) the class, and was headed for a career making license plates. As if to read my mind, a teacher said, "Don't worry. They all go through this stage, and then you can sit back, relax, and enjoy them." My mother listened and said nothing.

When I was in my forties, I spent a lifetime waiting for the phone to ring and the cars to come home, the front door to open.

My friends said that when my kids got married I could stop worrying and lead my own life. I wanted to believe that, but I was haunted by my mother' s wan ( 淡淡的 ) smile and her occasional words, "You look pale. Are you all right? Call me the minute you get home."

Can it be that parents are sentenced to a lifetime of worry? Is concern for one another handed down like a torch to blaze the trail of human frailties and the fears of the unknown? Is concern a curse? Or is it a virtue that elevates us to the highest form of life?

One of my children became quite irritable recently, saying to me, "Where were you? I' ve been calling for three days, and no one answered. I was worried! ! !"

I smiled a wan smile.

1.What can we know about the author’s mother from the passage?

A. She seems to laugh at the author.        

B. She is not concerned about the author.

C. She has a thorough understanding of the author.     

D. She tries to give the author some encouragement.

A. She was less concerned about her children.          

B. She couldn't stop worrying about her children.

C. She would like her children to see her often.        

D. She became more patient with her children.

3.Why did the author smile a wan smile at the end of the passage?

A. She wanted to learn from her mother.                

B. She stopped worrying about her children at last.

C. She succeeded in tricking her children.              

D. She got a kind of satisfaction from her child's concern.

4.The main purpose of the passage is to tell us that ______.

A. the concern between parents and children is natural

B. parents’ love for their children is selfless

C. parents show more concern for their children        

D. parents will worry about their children all their lives
