Few minor 1 injuries are as painful as the dreaded 2 paper cut. Just thinking about it probably makes you cringe. However, these cuts are usually small, hardly noticeable, and rarely bleed. So what makes them so painful?
很少有一些小伤能够像被纸划伤那样让人疼痛和害怕。光是想一想可能就让你不寒而栗了。然而，这种划伤通常伤口很小、很难被察觉到并且不怎么会流血。那为什么被纸划伤会这么疼呢？
A paper cut is similar to a cut with a razor blade, with one major difference. A razor blade makes a smooth, clean incision 3 in the skin, leaving behind few if any foreign particles that might cause the wound to become infected. Although it might hurt initially 4, the pain brought on by a small razor cut usually fades after a few minutes.
被纸划伤跟被剃须刀片划伤很像，但是有一点不同。剃须刀片造成的伤口较为平整，几乎不会留下任何会导致伤口感染的异物。虽然刚被剃须刀片划伤的时候很疼，但是过几分钟疼痛感就会慢慢消退。
Like a superficial cut by a razor blade, a paper cut smoothly 5 parts the skin, but while a clean razor leaves little behind to irritate the wound, a paper cut deposits material that really stings.
被纸划伤的伤口和剃须刀片造成的伤口一样，也很平整。但是干净的刀片不会留下任何物质去刺激伤口，而纸划伤口却会留下一些让人感到疼痛的物质。
Paper is made of pressed wood mulch, and a variety of chemicals. When paper cuts into the skin, chemical coated fibers 6, as well as bacteria and tiny particles remain in the wound and stimulate 7 pain receptors in the skin.
纸是由压缩木片和多种化学物质构成的。当纸划过皮肤时，化学涂层纤维、细菌和细小颗粒物就会留在伤口里，对皮肤里的痛觉感受器产生刺激。
Because the cut is usually small and shallow, the skin on either side of the wound closes quickly, trapping the fibers and other particles inside. The result is a good deal of pain, and since the closed wound doesn’t allow for much bleeding, the pain seems entirely 8 out of proportion to a cut that you can barely detect.
由于伤口通常很小且很浅，伤口会很快愈合，同时会把纤维和其他粒子留在伤口里面。所以，你才会感到十分疼痛，由于闭合的伤口几乎不会流血，所以说，即使伤口小到你几乎察觉不到，但是伤口造成的疼痛感却是要人命的！
