absorb 来自拉丁语 absorbere = ab（离开）+ sorbere（吸入）→ 吸进去，完全纳入。核心义项：① 吸收（物理，absorb water / heat = 吸收水分/热量）；② 学习吸收（absorb information / knowledge = 吸收信息/知识）；③ 全神贯注（be absorbed in = 全神贯注于）；④ 承受，消化（absorb the costs / shock = 承受成本/冲击）。关键：所有义项都是「向内纳入」——物理上吸收，知识上学习，注意力上投入，经济上承受。区别：absorb（把外部纳为己有，多维度）vs. take in（接收，口语化）vs. immerse（沉浸，更强调主动投入状态，immerse oneself in = 沉浸于）。
释义
1
v.吸收（物理，液体/热/光）
Dark surfaces absorb more heat than lighter ones, which is why cities with extensive asphalt often experience higher temperatures.
深色表面比浅色表面吸收更多热量，这就是为什么拥有大量沥青的城市往往温度更高。
2
v.学习吸收（知识、信息）
Young children have a remarkable capacity to absorb new languages quickly and seemingly effortlessly.
幼儿具有迅速且看似毫不费力地吸收新语言的非凡能力。
3
v.全神贯注（be absorbed in）
She was so completely absorbed in her reading that she failed to notice the hours passing.
她如此完全地专注于阅读，以至于没有注意到时间流逝。
4
v.承受，消化（成本、冲击）
The larger company agreed to absorb all outstanding debts as part of the acquisition deal.
较大的公司同意作为收购协议的一部分，承担所有未偿债务。
语感
absorb = 向内吸纳——物理吸收，学习消化，全神贯注，承受冲击，都是「纳进来」
吸收消化（知识）全神贯注承担（成本）
最高频搭配：absorb information / knowledge（吸收信息/知识）；be absorbed in（全神贯注于：be absorbed in work = 专心工作）；absorb the cost / impact（承担成本/冲击）；absorb moisture / heat / light（吸收水分/热量/光）。辨析：absorb（把外部纳为内部，向内的动作）vs. immerse（沉浸，主动将自己置于其中，immerse oneself in = 使自己沉浸于）vs. acquire（获取，得到，偏向主动追求）。
陷阱
⚠️be absorbed in（全神贯注，固定介词 in）
✗
He was completely absorbed by the documentary and didn't hear his phone ring.
他完全沉浸于纪录片，没有听到手机响。（absorbed by 不自然，应改为 absorbed in the documentary）
be absorbed in（全神贯注于某事）固定介词 in；absorbed by 可以用于物理义（被…吸收），但「全神贯注」义要用 be absorbed in
✓
He was completely absorbed in the documentary and didn't hear his phone ring.
他完全专注于纪录片，没有听到手机响。
⚠️absorb vs. immerse：被动吸入 vs. 主动沉浸
Students are encouraged to immerse themselves in the target language by watching films, reading widely, and speaking with native speakers.
✗
immerse = absorb（吸收，沉浸，可以互换）
✓
immerse oneself in（主动沉浸，是反身动词——自己主动把自己放进那个环境里）；be absorbed in（全神贯注，被某事吸引，是被动或状态描述）；此句是学生「主动将自己置于目标语言环境中」，是主动行为，用 immerse oneself in 准确
鼓励学生通过看电影、广泛阅读和与母语者交流来沉浸于目标语言。（immerse oneself in = 主动将自己置于其中，比 absorb 的「被动吸入」更强调主动性）
