be confident that

英 /bi kənˈfɪdənt ðæt/美 /bi kənˈfɪdənt ðæt/

短语动词

确信;对……有信心

词义解析

该短语的核心含义是“确信”或“有信心”,表示说话者对某个事实、判断或结果持有坚定的信念。其本义源自“confident”一词,意为“有信心的、自信的”,后接“that”从句,将信心具体化到某个命题上。引申义包括:1) 对事实的确定,如“I am confident that the report is accurate.”;2) 对能力的信任,如“She is confident that she can pass the exam.”;3) 对未来的乐观期待,如“We are confident that the project will succeed.”。各义项均围绕“内心确信”这一核心,区别在于确信的对象是事实、能力还是结果。

词源解析

“confident”源自拉丁语“confidere”,由前缀“con-”(加强)和“fidere”(信任)构成,字面意思为“完全信任”。“be confident that”是“be + 形容词 + that从句”的结构,其中“that”引导宾语从句,表示信任的具体内容。记忆时可拆解为“con-”(完全)+“fidere”(信任),即“完全信任某事为真”。

常见语境

该短语在多种场合使用,语气和含义略有不同:1) 学术写作中,表示基于证据的坚定判断,如“We are confident that the data support our hypothesis.”,语气正式、客观;2) 商务邮件中,表示对结果或能力的信心,如“I am confident that our team can meet the deadline.”,语气专业且积极;3) 日常口语中,表达个人信念,如“I'm confident that it will rain tomorrow.”,语气轻松自然;4) 新闻报道中,用于转述某方的确信态度,如“Officials are confident that the situation will improve.”,语气中立;5) 法律文本中,较少使用,但可表示对法律判断的把握,如“The defense is confident that the evidence will be dismissed.”,语气严谨。

语法说明

该短语为“be动词 + confident + that从句”结构,其中“be”需根据主语和时态变化。常见句型:1) 主语 + be + confident + that + 完整句子,如“They are confident that the plan works.”;2) 可用于被动结构,如“It is confident that...”(较少见,通常用“It is believed that”);3) 可接“about”或“of”代替“that”,但“that”后接从句,“of”后接名词或动名词,如“I am confident of his success.”。易错点:一是在“that”从句中误用虚拟语气,实际上该短语后通常用陈述语气;二是将“confident”误用为“confidential”(机密的);三是混淆“be confident”与“be sure”,前者强调内在信心,后者强调客观确定。

近义比较

与“be confident that”近义的表达有“be sure that”、“be certain that”、“believe that”等。区别在于:1) “be sure that”更强调主观上的确定性,语气口语化,如“I'm sure that I locked the door.”;2) “be certain that”与“sure”类似,但更正式,如“We are certain that the results are accurate.”;3) “believe that”表示相信,但信心程度较低,可能基于信念而非证据,如“I believe that he is honest.”。使用时,若表达强烈的信念或基于证据的判断,用“confident”;若表达主观确定,用“sure/certain”;若表达一般性相信,用“believe”。

常见误区

该短语属于中性偏正式语域,日常口语和书面语均可使用,但正式场合更显专业。无贬义色彩,但需注意语气过强时可能显得自负,如“I am 100% confident that I will win.”,在谦逊语境中可改用“I feel confident that...”或“I am fairly confident that...”。常见误用包括:1) 将“confident”误拼为“confidant”(密友);2) 在“that”从句中误用“will”表示未来,如“I am confident that he will come.”正确,但“I am confident that he comes.”则错误;3) 将“be confident that”与“be confident in”混淆,后者后接名词或代词,如“I am confident in his ability.”。
