What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today's leading killers, such as heart diseases, cancer, and aging itself, will become distant memory.
In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells(细胞) are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs(器官). The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on---in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imagine that the advance in technology may be changing the most basic conditional human existence, but many technical problems still must be cleared up on the way to this wonderful future.

All of my childhood and early, adult life, my mom weighed over 220 pounds (one pound = 0.454 kilograms). I could feel the pain that my mom experienced with her fatness.
I was never uncomfortable about my mother, but I think she was uncomfortable about herself, and that feeling was painful for all of us. And she began to lose weight.
After more than twenty years of battling obesity（肥胖）, my mother completed a forceful eighteen-month diet that left her ninety pounds lighter than before. A new woman was born! At age twenty-eight, I got a new mom! For the first time, I met the woman my mother truly was, the beautiful little lady under the fatness. It wasn’t so much her new body that was the surprise, but rather her new spirit.
To celebrate her new size and to devote herself to dancing again, my mother joined a “Mrs. Forty-Plus” competition, where she would have to model, give a speech and provide a dance performance. She told our family that she did not care if she won — she simply had always wanted to perform on stage.
She told each one of us, “I’m not doing it to win; I’m doing it to dance!”
The competition was exciting! I prayed(祈祷) that my mom would win, but while watching her on stage I was simply overjoyed just by her effort. To me, she had already won. She posed to perfection, her speech brought tears to everyone’s eyes, and her performance was wonderful.
That night, at age fifty-three, my mother was crowned (为......加冕) “Mrs. Forty-Plus”. She was the first person in our family to ever win such a title.

In good years, when there is enough food for their animals, they trade their skins and their goats and camel hairs with the people of oases for wheat and fruit. But in bad years, when there is not enough food for their animals, the people of the desert would attack the oases people.
