overgrow 表示“长满、蔓延覆盖”时是及物动词，直接跟被覆盖的对象作宾语；受中文“在…上长满”的影响添加介词 on 是错误的。若要用介词，可用 The wall was overgrown with ivy.

语域：neutral 常见场景：describing vegetation covering surfaces、describing someone or something too large for a space/garment 这里指及物用法（vt），多用于书面或叙事语境，如描写植物长满覆盖某物，或指人长得太大不再适合原有东西；口语中更常说 be overgrown with 或 grow too big。
这些词与 overgrow 的 -grow 部分押韵：grow, throw, flow, slow, know, though（都读 /əʊ/）。注意拼写以 -ow 结尾的 now /naʊ/ 和 how /haʊ/ 发音不同，不要混淆。
