vt. 推论，推断；演绎出

三单：deduces；过去式：deduced；过去分词：deduced；现在分词：deducing→名词：deduction(演绎；扣除)→形容词：deductive(演绎的)→副词：deductively→同义：infer(推断)；conclude(推断)

deduce、infer、conclude、reason
1. deduce（动词）：“推断（演绎法，从一般到特殊）”（如 deduce a conclusion from facts；根据已知规律推导具体结论）；
2. infer（动词）：“推断（归纳法，从特殊到一般）”（如 infer a rule from examples；根据具体事例归纳规律，与 deduce 逻辑方向相反）；
3. conclude（动词）：“得出结论（最终判断）”（如 conclude after discussion；经过分析后得出最终结论，比 deduce 更侧重 “结果”）；
4. reason（动词）：“推理（逻辑思考）”（如 reason carefully；reason with facts，泛指 “逻辑思考过程”，非特指 “演绎或归纳”）。

deduce，conclude，gather，infer，judge
这几个词的共同意思是“推断”。其区别在于:
infer指从不太充分的论据或前提中推断出结论；
conclude指通过推理或判断而得出结论；
deduce指有充分根据地推论或逻辑上地演绎；
gather指综合事物得出印象或感想等；
judge通常指经过仔细鉴定或评价之后作出的决断。
例如From his a manner of dress and style of living，I gather that he is man of considerable means.从他的穿着式样和生活方式，我揣想他是个相当富有的人。
