易错句子He was accessary of the robbery.

正确表达He was accessary to the robbery.

accessary 作形容词表示“参与（犯罪的）、从犯的”时，固定搭配介词 to，不能换成 of；汉语说“某桩罪案的从犯”容易让人按所属关系类推成 of。改成 to 之后，to 引出他所参与的那桩罪行。

易错句子She was accessary to plan the theft.

正确表达She was accessary to the theft.

accessary to 里的 to 是介词而非不定式符号，后面只能接名词或动名词，不能接动词原形；受“帮忙去做某事”的汉语表达影响容易写成 to do。改为直接接名词 the theft，若强调行为则说 accessary to planning the theft。
