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 why:The 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 | 与 for 连用 | 与 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?
