（单词翻译）

 The London Olympics are about to begin, and spectators will again be riveted1 by feats2 that would have been impossible when the modern Olympics began in 1894.

 
Jaw-dropping records are attainable3 in part because of the advances in materials science. New materials have led to equipment like super light and strong vaulting4 poles and bathing suits that improve the flow of bodies and water. Such developments are detailed5 in a series of articles in the journal Nature Materials.
 
 
The scientists say other advances are afoot that build sensors6 into athletes' clothing for, for instance, measuring performance and training or protective gear that repairs itself when damaged. And advances in materials science can help Olympians internally as well. Elite7 athletes may tear cartilage or break bones, but cartilage doesn't have enough blood and cells to mend well. And sometimes bones just can't naturally abridge8 the break. 
 
 
So scientists are homing in on the best combinations of bio-compatible materials, along with growth factors and other compounds as well as implanted cells and proteins to help mend what have been until now nearly intractable injuries. So that world-class athletes can push the limits of sports and science.
