修改原因
修改前This price sticker doesn't take off, even with hot water.
修改后This price sticker doesn't come off, even with hot water.
取下贴纸可以用 take off，因此容易把它套进原句。但在这个含义中，take off 需要有人去取下某物：I can't take off this sticker。如果主语是贴纸，描述它能否脱离表面，就用 come off：the sticker doesn't come off。
还要注意 Come off it!，这是非正式的英式说法，表示“别胡说了”或“我才不信”。它表达怀疑，与物品脱落无关：Come off it, you didn't really meet the Prime Minister!

came off — 拉门把手时，把手脱离了门，落在手里，所以选 came off。Took off 不接宾语时可以表示飞机起飞或突然走红，都不符合这里门把手脱落的情境。
描述一次日常小意外：纽扣、把手或鞋跟之类的东西掉了或断了。说明在哪里发生，以及你怎样处理。
