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 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.”

If women are mercilessly exploited year after year, they have only themselves to blame, because they tremble at the thought of being seen in public in clothes that are out of fashion. They are always taken advantage of by the designers and the big stores. Clothes which have been worn only a few times have to be put aside because of the change of fashion. When you come to think of it, only a woman is capable of standing in front of a wardrobe packed full of clothes and announcing sadly that she has nothing to wear.

Changing fashion is nothing more than the intentional creation of waste. Many women spend vast sums of money each year to replace clothes that have hardly been worn. Women who cannot afford to throw away clothing in this way, waste hours of their time altering the dresses they have. Skirts are lengthened or shortened; necklines are lowered or raised, and so on.

No one can claim that the fashion industry contributes anything really important to society. Fashion designers are rarely concerned with vital things like warmth, comfort and durability(耐用) . They are only interested in outward appearance and they take advantage of the fact that women will put up with any amount of discomfort, as long as they look right. There can hardly be a man who hasn’t sometimes in his life smiled at the sight of a woman shaking in a thin dress on a winter day, or delicately picking her way through deep snow in high-heeled shoes.

When comparing men and women in the matter of fashion, the conclusions to be drawn are obvious. Does the constantly changing fashion of women’s clothes, one wonders, reflect basic qualities of instability? Men are too clever to let themselves be cheated by fashion designers. Do their unchanged styles of dress reflect basic qualities of stability and reliability? That is for you to decide.

69. Designers and big stores always make money_____.

   A. by mercilessly exploiting women workers in the clothing industry

   B. because they are capable of predicting the new fashion

70. To the writer, the fact that women change their old-fashioned dress is seen as_____.

   A. a quality of instability         B. a waste of time and money

   C. an expression of taste        D. an expression of creativity

71. The writer would be less critical if fashion designers placed more stress on the_____.

   A. cost        B. appearance     C. comfort     D. suitability

72. By saying “ the conclusions to be drawn are obvious”, the writer means that_____.

   A. women’s changeableness in their choice of clothing was often laughed at

   B. women are better able to put up with discomfort

   C. men are also exploited greatly by fashion designers

   D. men are more reasonable in the matter of fashion

Looking back on my childhood, I am convinced that naturalists are born and not made. Although we were all brought up in the same way, my brothers and sisters soon abandoned their pressed flowers and insects. Unlike them, I had no ear for music and languages. I was not an early reader and I could not do mental arithmetic.

   Before World War I we spent our summer holidays in Hungary. I have only the dim memory of the house we lived in, of my room and my toys. Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a clear memory of the dogs, the farm animals, the local birds, and above all, the insects.

   I am a naturalist, not a scientist. I have a strong love of the natural world and my enthusiasm had led me into varied investigations. I love discussing my favorite topics and enjoy burning the midnight oil reading about other people’s observations and discoveries. Then something happens that brings these observations together in my conscious mind. Suddenly you fancy you see the answer to the riddle, because it all seems to fit together. This has resulted in my publishing 300 papers and books, which some might honor with the title of scientific research.

   But curiosity, a keen eye, a good memory and enjoyment of the animal and plant world do not make a scientist: one of the outstanding and essential qualities required is self-discipline, a quality I lack. A scientist, up to a certain point, can be made. A naturalist is born. If you can combine the two, you get the best of both worlds.

   A. was interested in flowers and insects in his childhood

   B. lost his hearing when he was a child

   A. he didn’t live very long with them

   C. he was too young when he lived with them

   D. he was fully occupied with observing nature

63. It can be inferred from the passage that the author was_____.

   A. a scientist as well as a naturalist                       B. a naturalist but not a scientist

   C. no more than a born naturalist                         D. first of all a scientist

64. The author says that he is a naturalist rather than a scientist probably because he thinks he_____.

   A. has a great deal of trouble doing mental arithmetic

   B. lacks some of the qualities required of a scientist

   C. just reads about other people’s observations and discoveries

   D. comes up with solutions in a most natural way
