“deceive”最基本和常见的含义就是“欺骗；蒙骗；使误信”，强调通过虚假的信息、行为或表象来误导他人，使其产生错误的认知或做出错误的判断。例如：He deceived her into thinking he was rich.（他欺骗她，让她以为他很富有。） 这里“deceived her into thinking...”就清晰地体现了欺骗她并使其产生错误想法的意思。
主动语态：当主语是实施欺骗行为的人或事物时，用主动语态。例如：The con artist deceived many people with his fake investment scheme.（这个骗子用他的虚假投资计划欺骗了许多人。）此句中“the con artist”（骗子）是主动实施欺骗行为的主体，使用主动语态“deceived”。
被动语态：当强调被欺骗的对象时，可用被动语态。例如：She was deceived by his smooth talk.（她被他花言巧语所欺骗。）这里“she”是被欺骗的对象，句子用被动语态“was deceived”来突出这一情况。
