易错句子Do you sure about the answer?
正确表达Are you sure about the answer?
sure 是形容词,不是动词,疑问句要用 be 动词 are,而不是助动词 do。中文“你确定吗”容易让人把“确定”当成动词,但英语中 sure 作形容词,需搭配 be。

正确表达I am sure that he will come.
sure 后接 that 从句时直接说 sure + that 从句,不加介词 of;of 只用于名词、代词或动名词前,如 sure of success / sure of it。中文“我确信他会来”容易逐字套成 sure of that...,但 that 从句前不用 of。
