seriously

Compared meaning: to a severe or serious degree (adverb).

比较义项：严重地（副词，表示程度深、情况严重）。

• seriously 本词

  Formal and often clinical in tone; the standard choice for describing severe illness or injury (seriously ill, seriously injured); unlike badly, it never means 'poorly' and rarely modifies everyday needs or wants.

  语气正式，常带有医疗、临床色彩，是描述严重疾病或伤势的标准用词（如 seriously ill、seriously injured）；与 badly 不同，它绝不表示“拙劣地”，也很少修饰日常的需要或想要。

  Her grandmother is seriously ill and has been in the hospital for two weeks.

  她的祖母病得很严重，已经在医院住了两周。

• badly

  Informal and very common in everyday speech for severe harm or strong need (badly hurt, badly beaten, badly needed); it is ambiguous, since badly can also mean 'poorly', and it rarely combines with formal words like ill.

  口语化，日常表达中十分常见，用于表示严重的伤害或强烈的需要（如 badly hurt、badly beaten、badly needed）；它本身有歧义，因为 badly 也可以表示“拙劣地”，而且很少与 ill 这类正式词搭配。

  The boxer was badly beaten and could barely stand after the fight.

  那名拳击手被打得很惨，赛后几乎站不起来。

Seriously and badly both mean to a severe degree. Seriously is formal, the standard word for illness or injury, as in seriously ill. Badly is informal, for strong harm or need, as in badly hurt or badly needed, but it can also mean 'poorly'.

seriously 和 badly 在表示“严重地”这一程度义上较为接近，但语域和搭配不同：seriously 更正式，常见于医疗、新闻等语境（如 seriously ill）；badly 更口语化，常见于日常表达（如 badly hurt、badly beaten），且本身还兼有“拙劣地”的意思，需靠语境区分。这里不比较 seriously 表示“认真地”的义项（如 take something seriously），也不比较 badly 表示“拙劣地”的义项。
