repellent

Compared meaning: causing dislike or discomfort (adjective).

比较义项：令人不快、讨厌的（形容词）。

• harsh

  Harsh stresses roughness or severity, often describing sound, light, weather, or a stern tone; stronger and more specific than 'unpleasant', without implying disgust like 'repellent'.

  harsh强调粗糙或严厉，常用来形容声音、光线、天气或严厉的语气；比unpleasant语气更强、含义更具体，但不像repellent那样带有厌恶之意。

  Her harsh tone made everyone in the meeting go quiet.

  她严厉的语气让会议室里的每个人都安静了下来。

• unpleasant

  Unpleasant is a mild, general word for anything that causes dislike or discomfort, without harsh's roughness or repellent's strong disgust; it fits ordinary everyday complaints.

  unpleasant是语气较轻、较通用的词，泛指任何引起不快或不适的事物，没有harsh的粗糙感，也没有repellent那种强烈的厌恶感，常用于日常的抱怨。

  The bus ride was hot and unpleasant, but not really dangerous.

  这趟公交车车程闷热又难受，但并不算真正危险。

• repellent 本词

  Repellent describes something that provokes strong dislike or disgust, often close to physical revulsion, and is more formal or literary than 'unpleasant' or 'harsh'.

  repellent形容引起强烈厌恶甚至近乎生理反感的事物，语气比unpleasant和harsh都更正式、更强烈。

  The rotting food gave off a repellent smell that turned our stomachs.

  腐烂的食物散发出一股令人反胃的气味，让我们感到恶心。

Harsh, unpleasant, and repellent all describe something causing dislike, but strength differs. Harsh stresses roughness or severity, often for sound, light, or tone. Unpleasant is mild and general, for anything causing discomfort. Repellent is strong and formal, close to disgust. Not compared: harsh describing weather.

这三个词都可以形容令人不快的事物，但程度和用法不同：harsh强调粗糙、刺耳或严厉，常用于声音、光线、语气或对待方式；unpleasant是最普通、程度较轻的词，泛指任何引起不快或不适的事物；repellent语气较强、较正式，强调强烈的厌恶甚至生理上的反感。另外，repellent还常作名词表示“驱虫剂”，这里不作比较；harsh也可以形容恶劣的气候或环境，这里同样不展开。
