And so no single fiber stretches all the way across the room.

没有哪根纤维的长度足够横穿整个教室。

The heat transmitted through a single optical fiber makes the molecules of collagen-the main structural protein of all connective tissues-bond and close the wound.

温度通过一根光纤进行传导，会将所有结缔组织的主要结构蛋白的胶原蛋白分子结合在一起使得伤口愈合。

But if, in contrast, there is the right kind of pattern of overlap and continuity, same rope, even though, even if no single fiber makes it all the way across.

但如果没有发生意外的话，纤维就这样交叠连续着编织在一起，这根绳子就保持同一性，即使没有一根纤维能贯穿始终。

The benefits cannot be overstated, and the role of proteins and amino acids stretch to virtually every single fiber of our being, including those very fibers of muscle fitness enthusiasts love to pursue.

它的好处怎么强调都不为过，蛋白质和氨基酸的作用几乎延伸到我们身体的每一根纤维，包括那些肌肉健身爱好者喜欢追求的纤维。
