中文段落：

“刀口舔血”这个成语常常用来形容一种非常危险且勇敢的行为，就像一只豹在猎食时，勇敢地穿梭在猎物与陷阱之间，稍有不慎就可能受伤甚至丧命。豹，作为自然界中的顶级捕食者，它的生活充满了挑战和冒险。它们不仅拥有敏锐的感知力和强壮的身体，更有着无与伦比的勇气和决心。在狩猎时，豹经常需要在猎物警觉前迅速而准确地发动攻击，这需要极高的耐心和精确度。正如“刀口舔血”所描述的那样，豹的这种行为既勇敢又危险，稍有差池就可能受伤甚至丧命。

英文段落：

The phrase "licking blood from the knife's edge" often describes a dangerously brave act, much like the behavior of a leopard stalking its prey. A top predator in the natural world, the leopard's life is filled with challenges and adventures. Possessing keen senses, a powerful body, and unmatched courage and determination, leopards must act swiftly and precisely to take down their prey before it becomes aware of their presence. Just as described by the phrase "licking blood from the knife's edge," this behavior is both brave and perilous, with any misstep potentially leading to injury or even death.

The leopard's bravery and determination extend beyond hunting, as they demonstrate remarkable prowess in protecting their territory and cubs. When faced with intruders, leopards will attack without hesitation, even if it means confronting much larger opponents. This fearless courage earns the leopard the title of a true warrior in the natural world.

However, the life of "licking blood from the knife's edge" is not always successful. Sometimes, leopards can get injured or even killed due to overaggression. But this is the law of nature, and only the bravest and smartest predators survive. As a representative of this lifestyle, the leopard undoubtedly ranks among the most awe-inspiring creatures in nature.
