单脚跳的英语

to hop is to move in short, often jerky leaps as does a bird, frog or rabbit. Hopping lacks the grace and speed of skipping or bounding, or the energy of leaping and springing.

hop是指以小且经常是急促的步伐跳跃，就像鸟、青蛙或兔子那样。hopping缺少像skipping或bounding的优雅和迅捷，也没有leaping和springing那样有力量。

to jump is to spring into the air, especially to spring free from the ground or other base by muscular action of feet and legs.

jump是指跳向空中，特别指靠双脚和双腿的力量跳离地面或其它物体表面。

粗略地讲，hop是“小碎步跳”，jump是“有力量地跳跃”。
