“轰”的一声响，还没来得及看到人脸，一辆后轮巨大的摩托就从身边呼啸而过。很多人都经历过这样的场景。摩托车俗称“肉包铁”。调查显示，在已发生的交通事故中， 摩托车造成的伤亡系数最高。以至于急诊室医生都将其称为“捐献摩托”。

Donorcycle is a combination of organ donor and motorcycle; the term apparently originates from emergency room personnel who often see motorcycle accident victims. It alludes to the high percentage of donated organs that come from motorcyclists.

Donorcycle是由organ donor（器官捐献者）和motorcycle（摩托车）两个词组合而成，最初起源于急诊室医生的说法，他们经常看到摩托车交通事故的受害者。这种说法暗指器官捐献中很大比例来自摩托车驾驶者。

Inexperienced riders, especially those who have not taken training courses, are more likely to die. Sport bikes, which emergency-room doctors call “donorcycles,” as in organ donation, are more dangerous than their less powerful counterparts.

缺乏经验的摩托车驾驶者，特别是没有接受过驾驶训练的人，更容易因摩托车事故去世。运动摩托（一些急诊室医生称之为捐献摩托）比其他车辆更加危险。

例句：

Guess what happens when you ride a donorcycle without a helmet?

不戴头盔就骑捐献摩托，猜猜会发生什么？

Get the transplant team ready, we have one more donorcycle casualty arriving.

让移植小组准备好，还有一位捐献摩托事故伤者就要到了。
