表示对……有信心;确信……;相信……,强调主语(通常是人)对某事物、某种结果或自身能力的确定性信心。
主语 + be (am/is/are/was/were) + confident of + 名词/代词/动名词(ving)
(注:"of"是介词,后面必须接名词性成分,不能接动词原形或从句。)
接名词/代词:对某事物/某人有信心
He is confident of his success.(他对自己的成功有信心。)
I'm confident of it—we'll finish on time.(我确信这一点——我们会按时完成。)
She's confident of her team's ability.(她对自己团队的能力有信心。)
接动名词(ving):对“做某事”有信心/确信能做到
We are confident of passing the exam.(我们有信心通过考试。)
Are you confident of getting the job?(你有信心得到这份工作吗?)
He was confident of winning the race.(他确信能赢得比赛。)
be confident that...:后面接从句(表达“确信某件事会发生”)
例:I'm confident that we will win.(我确信我们会赢。)
对比:I'm confident of winning.(我有信心赢。)(更简洁,强调“对行动的信心”)
have confidence in...:与"be confident of"同义,但结构不同("have confidence in" = "be confident of")
例:He has confidence in his success.(= He is confident of his success.)
例:We have confidence in passing the exam.(= We are confident of passing the exam.)
主语通常是人(表示人的信心),偶尔也可用于物(强调“某事物有成功的把握”),但较少见:
例:The new strategy is confident of boosting sales.(新策略有把握提升销量。)
否定形式:在"be"后加"not",即"be not confident of..."(对……没信心)
例:I'm not confident of solving this problem alone.(我对独自解决这个问题没信心。)
"be confident of"是表达“信心/确信”的常用短语,核心是对“名词性内容”的信心,需注意介词"of"后接的成分(名词/代词/动名词)。通过例句对比,能更清晰区分它与"be confident that..."的用法差异~
