hardly

Compared meaning: almost not, hardly at all (adverb).

比较义项：几乎不，几乎没有（副词）。

• barely

  Barely stresses a very narrow margin — something happened, but only just; it pairs naturally with achievement verbs like pass, survive, or afford, unlike hardly or scarcely.

  barely强调差一点点就没能做到——事情发生了，但只是勉强做到；常与pass（通过）、survive（幸存）、afford（负担得起）等表示“达成”的动词搭配，这点和hardly、scarcely不同。

  She barely passed the driving test, missing a perfect score by one point.

  她驾照考试只是勉强通过，只差一分就能得满分。

• hardly 本词

  Hardly is the everyday, neutral choice, most common in speech; it combines naturally with can/could and with ever to mean almost never.

  hardly是最常见、最中性的日常用词，口语中最为常用；常与can、could连用，也常与ever搭配表示“几乎从不”。

  He hardly ever calls his parents now that he lives abroad.

  他现在住在国外，几乎从不给父母打电话了。

• scarcely

  Scarcely is formal and rather literary, common in written English; it is often placed first for dramatic effect, which forces inverted word order.

  scarcely是正式、书面色彩较浓的词，常见于书面英语；常放在句首加强语气，句子随之使用倒装语序。

  Scarcely had the meeting started when the fire alarm went off.

  会议刚开始，火警警报就响了。

Barely, hardly, and scarcely all mean almost not, but tone and style differ. Barely stresses a narrow, just-achieved margin. Hardly is the most common word in speech, often with can or could. Scarcely is formal and literary, often starting a sentence with inverted word order.

barely、hardly、scarcely在“几乎不”这层意思上很接近，但语气和文体不同：barely强调“勉强达成”的窄幅差距，hardly是口语中最常用、最中性的说法，scarcely则更正式、书面化，常用于倒装句式。
