I stared at my hands, twisting and untwisting my fingers, as I finally spoke.

自己的双手，十指时伸时屈。最终，说话了。

If all else fails, a corkscrew can actually be a great tool for untwisting tough knots, for example in shoelaces.

如果都失败了，螺锥不失为一个好工具用来松开很紧的结，例如鞋带。

Hiccup watched, fascinated, as he untwisted the claw attached to his right arm.

卡嗝，迷他解开绑在右臂上的爪子。

Well, I am, so untwist your boxers and deal with it.

已经在这了 所以不要不爽了 认了吧。
