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 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 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 condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.

小学课时特训系列答案Teachers and parents usually call attention to the pictures when they read storybooks to pre-school children. But a new study suggests that calling attention to the words and letters on the page may lead to better readers.
The two-year study compared children who were read in this way in class with children who were not. Those whose teachers most often discussed the print showed clearly higher skills in reading, spelling and understanding. These results were found one year and even two years later.
Shayne Piasta, an assistant professor of teaching and learning at Ohio State University, was an author of the study. She says most pre-school teachers would find this method manageable and would need only a small change in the way they teach. They already read story-books in class. The only difference would be increased attention to the printed text. “If you get children to pay attention to letters and words, it makes sense that they will do better at word recognition and spelling.” But she says research suggests that very few parents and teachers do this in a systematic way.
More than 300 children aged four and five were observed in classrooms. They came from poor families and were below average in their language skills. For thirty weeks, the children took part in a program called Project STAR--- Sit Together and Read. The project is based at Ohio State. It tests the short-term and long-term results of reading regularly to pre-school children in their classrooms.
There are different ways that adults can talk to children about print. They can point to a letter and discuss it, and even trace the shape with a finger. They can point out a word and discuss the meaning of the print or how the words tell the story. And they can talk about the organization of the print--- for instance, showing how words are written left to right in English.
