there is evidence that...
英 /ðeə r ɪz ˈɛvɪdəns ðæt/美 /ðɛr ɪz ˈɛvɪdəns ðæt/
phrase
有证据表明;有迹象显示
词义解析
该短语的核心含义是“存在证据表明某事”,通常用于引出基于证据的结论或推测。其本义强调“证据的存在”,即客观事实或数据支撑某个判断。引申义可表示“有迹象显示”,此时证据可能不确凿,带有推测成分。在不同语境中,它可表达从“确凿无疑”到“初步迹象”的递进,但始终强调证据的基础性。
字源分析
该短语由“there is”(存在)、“evidence”(证据)和“that”(引导从句)构成。“evidence”源自拉丁语“evidentia”,由“e-”(出)和“videre”(看)组成,意为“看得出来的东西”,即“明显的事实”。记忆时可联想“e-”(向外)加“videre”(看),即“看出来的”就是证据。
常见语境
该短语常见于学术写作,用于提出研究结果或文献支持,语气正式、客观。在新闻报道中,用于陈述调查或统计数据,强调事实依据。在日常口语中,使用较少,但可用于非正式讨论,语气较随意。在法律文本中,用于指代呈堂证供,语气严谨。在商务报告中,用于决策依据,语气理性。各场景中,核心含义不变,但正式程度和证据的可靠性要求不同。
用法须知
该短语为固定结构,后接that从句,从句中谓语动词时态需与主句一致。例如:There is evidence that the climate is changing. 易错点:不要漏掉“that”,或误用“which”。另外,“evidence”为不可数名词,不能用复数,也不加不定冠词“a”。
同义词区别
与“there is proof that”相比,后者强调确凿无误的证据,语气更强;而“there is evidence that”可包括间接或初步证据。与“it appears that”相比,后者更主观,基于观察而非证据;“there is evidence that”更客观。与“there are signs that”相比,后者更强调迹象,可能非实物证据。选择时,根据证据的可靠性和正式程度决定。
易错提醒
该短语属于中性正式表达,适用于书面和正式口语。避免在非正式场合过度使用,以免显得生硬。常见误用包括将“evidence”误作可数名词,或忽略“that”从句的完整性。此外,若证据不充分,应使用“some evidence”或“limited evidence”以保持准确。
