v.（情绪）压倒，使不知所措
He was completely overcome by grief when he heard the news.
听到这个消息，他被悲痛完全淹没了。
语感
overcome = 翻越过去——困难是山，overcome 是爬过去的动作
克服战胜压倒
be overcome with / by 是义项二的核心搭配：be overcome with emotion / grief / joy（被情绪/悲伤/喜悦压倒）。注意介词可以是 with 或 by，两者均正确。overcome difficulties / challenges / obstacles / fear 是义项一的高频搭配，高考作文极常用。区别于 conquer：conquer 更强调「彻底征服」，overcome 更强调「挣扎后翻越」。
陷阱
⚠️be overcome with/by：被情绪淹没（≠ 主动克服）
The audience was overcome with emotion as the final notes of the symphony faded.
✗
overcome with emotion = 努力克服情绪
✓
be overcome with/by + 情绪词 = 被某种情绪压倒、淹没（被动的情绪状态），不是「主动克服」
当交响乐最后的音符渐渐消逝，听众被情绪完全淹没了。（被动，被情绪压倒）
