相当于accidentally。

例句：►Imissedtheschoolbusbymistakethismorning.

mistake…for…把……错认成……。例句：►Don’tmakemistakesanymore.别再出错了。►ImistookherforourEnglishteacher.

我把她错认成我们的英语老师了。2.Thecustomerthoughtthepotatoeswerenotthinenough.顾客认为土豆不够薄。enough修饰名词时，不需要倒装。如:我有足够的钱。餐厅里的食物不太够。►Thereisn’tenoughfoodinthedinninghall.
