descend

Compared meaning: to move downward from a higher place (verb).

比较义项：从高处向低处移动（动词）。

• fall

  Fall suggests a sudden, often accidental or uncontrolled downward movement; it is common, everyday, informal vocabulary and does not imply the mover chose to go down.

  fall 表示突然的、往往是意外或失控的向下移动；是常见的日常口语词汇，并不暗示移动者是主动选择向下的。

  Be careful not to fall on the wet floor.

  小心不要在湿滑的地板上摔倒。

• descend 本词

  Descend describes a deliberate, controlled movement from a higher place to a lower one, often over some distance or height, and sounds more formal than fall.

  descend 表示从高处到低处有意识的、受控的移动，往往涉及一定的距离或高度，语气比 fall 更正式。

  The hikers began to descend the mountain before dark.

  徒步者们在天黑之前开始下山。

Fall and descend both mean to move downward. Fall suggests a sudden, accidental or uncontrolled movement; common, informal, no implied choice. Descend describes a deliberate, controlled movement from high to low, more formal than fall. Not compared: fall as autumn, or as a decrease.

这两个词都表示身体或物体向下移动，但语气和受控程度不同：fall 强调突然、意外、不受控制地跌落，语域随意；descend 强调有意识地、逐步地从高处走向低处，语域较正式。这里不比较 fall 的“秋天”“下降（数值）”等其他含义，也不比较 descend 的“血统上属于”“突然造访”等其他含义。
