原因

更新时间:2026-07-07 14:09:55   栏目: 英语词典

reason 是英语中表示“原因”的核心词汇,兼具名词和动词词性,读音为 /ˈriːzən/(美式)或 /ˈriːz(ə)n/(英式),中文谐音类似“瑞森”。作为名词时,它既可以解释事件发生的逻辑依据(如 The reason for his absence was illness),也可指人类的理性思考能力(如 a conflict between emotion and reason);作为动词则表示“推理”或“劝说”,例如 I reasoned that changing my diet would help

核心用法与搭配

1. 名词用法:解释“为什么”

基本结构

后跟介词 for 说明具体对象:The main reason for the delay is bad weather

引导定语从句常用 whyThe reason why she quit remains unclear

常见搭配

have reason to do sth(有理由做某事):They had reason to believe there could be trouble

by reason of(由于,正式用语):He succeeded by reason of hard work

2. 动词用法:逻辑推理与劝说

推理得出结论She reasoned that he must have forgotten the meeting

劝说某人I tried to reason with him, but he refused to listen

易混淆词对比:reason vs. cause

两者虽都表示“原因”,但侧重点截然不同:

 

维度 reason cause
核心含义 行为/决策的逻辑依据或动机 导致结果的直接客观因素
搭配习惯 for 连用 of 连用
例句 The reason for his anger is misunderstanding(主观原因) The cause of the fire was a short circuit(客观原因)
词性扩展 可作动词(推理、劝说) 可作动词(导致,如 Smoking causes cancer

 

总结reason 回答“为什么做某事”,cause 回答“什么导致了某结果”。

实用短语与场景

for no reason(无缘无故):He shouted at me for no reason

within reason(合情合理地):I’ll help you, within reason

listen to reason(听从道理):The child finally listened to reason and put down the toy

例句解析

解释原因
The reason why he failed the exam was that he didn’t study(他考试不及格的原因是没学习)。
此处 reason 强调主观行为(没学习)与结果(不及格)的逻辑关联。

理性与情感对比
In times of crisis, we must rely on reason rather than panic(危机时刻,我们应依靠理性而非恐慌)。
这里 reason 指人类的理智能力。

动词推理用法
She reasoned that if we left early, we could avoid traffic(她推断如果早点出发就能避开堵车)。

掌握 reason 的关键在于区分其“逻辑解释”的核心属性,并注意与 cause 的场景差异。无论是写作还是口语,准确使用这两个词能让表达更精准——比如解释迟到时用 reason for being late,描述事故根源时用 cause of the accident 。你能想到哪些生活场景中需要刻意区分这两个词吗?
