deduce

这几个词共同的意思是“推断”。它们的区别在于: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。

She had concluded from that her grandmother did not like her.她已从那一点得出结论,断定她祖母不喜欢她。

If you saw a doctor leaving a house, you might deduce the fact that someone in the house was ill.你要是看到医生从一家出来,你就可以推想那家有人生病。

We see smoke and infer fire.我们看到烟,从而推断有火。

Judging from what you said, they ought to succeed.从你说的情况看来,他们应当能成功。

这组词的区别是：deduce的意思是“演绎、推理”,而deduct的意思是“扣除”。两词意思截然不同,可它们的名词形式却都是deduction。

这些动词都含“推断”之意。

infer指从已提供的论据或从已接受的前提出发而推断出的结论。

deduce指有充分根据的推论，也指逻辑学上的演绎。

conclude指得出符合逻辑的结论。

gather指从听到的情况推测、判定。

judge多指经过仔细鉴定或评价之后作出决断。
