four-legged

adj.

有四根桅樯的；

1. On four legs, they resemble the great timber wolves that make the tundra their home.
   当他们四足的时候，象来自冻土地带的森林巨狼。
2. Whatsoever goeth upon the breast on four feet, or hath many feet, or traileth on the earth, you shall not eat, because it is abominable.
   不论是用腹部爬行的，或用四足爬行的，或多足的，凡是地上的爬虫，你们都不可吃，因为都是可憎恶的。
