记忆方法
将“dud”想象成一个虚构的名词，比如“小木头人”（dim wooden dummy），这样可以通过“dim”和“wooden”两个形容词来帮助记忆，而“dud”则代表这个没有生命的“小木头人”。这种形象化记忆法可以帮助你记住这个单词。

- dud (n.)
- c. 1825, "person in ragged clothing," from duds (q.v.). Sense extended by 1897 to "counterfeit thing," and 1908 to "useless, inefficient person or thing." This led naturally in World War I to "shell which fails to explode," and thence to "expensive failure."
