• climb

  A general, everyday word for the act of going up something by using hands and feet; used casually and in a wide range of contexts, not just mountains.

  一个通用的日常词汇，指用手脚向上攀爬的动作；用法随意，适用范围广，不局限于登山。

  The kids enjoyed a quick climb up the tree in the backyard.

  孩子们在后院的树上很快地爬了一下，玩得很开心。

• ascent 本词

  A more formal, often literary word for a sustained upward climb, typically describing the whole process of ascending a mountain or slope, not a casual action.

  一个更正式、常带书面色彩的词，通常描述持续向上攀登的整个过程，多用于登山或坡道，而非随意的动作。

  The ascent to the summit took the climbers nearly six exhausting hours.

  登顶的攀登过程让登山者们花了将近六个小时，十分疲惫。

Both words mean the act of climbing up. Climb is general and everyday, used casually for the act itself, in many contexts, not just mountains. Ascent is more formal, often literary, describing the whole process of climbing a mountain or slope, not a casual action.

两者都指“攀登、上升”的动作，但climb更常泛指攀爬这一具体动作本身，可用于任何攀爬场合；ascent更书面、正式，强调向上攀升的整个过程，常用于登山或海拔上升的语境。这里不比较ascent的其他义项，如“提高，晋升”。
