易错句子I was nonplus by his answer.

易错句子The unexpected question nonplussed.
正确表达The unexpected question nonplussed me.
nonplus 是及物动词，必须带宾语，说明“使谁困惑”；不能像汉语“困惑”那样单独作不及物动词使用，所以要说 nonplussed me。
perplex 是中性、通用的“让人想不通”，困惑的来源可以是难题、现象或某人的行为；nonplus 更强调因意外、窘迫而一时语塞、不知如何应对，语体偏书面，且常用被动 be nonplussed。若只是“不明白、想不通”，用 perplex 即可，不必用 nonplus。
flummox 偏口语、随意，多指被问题或局面一时难住；nonplus 更正式、更书面，并带有尴尬、下不来台的意味。日常口语说“被难住了”用 flummox 更自然，正式叙述并强调窘态时才用 nonplus，两者并非绝对不可换用。
confound 除“使人困惑”外，还可表示“驳倒、挫败”或“把…与…弄混（confound A with B）”；nonplus 只有“使困惑、使窘迫”这一层意思。语境涉及反驳观点或混淆两事物时只能用 confound，不能用 nonplus。
