important 是形容词，需要用副词修饰，而 vital 是形容词，不能修饰形容词，应改为副词 vitally。中文的“至关重要”容易让人误用 vital 直接修饰 important，但英语中应为“副词 + 形容词”。
Not this

Use this
This is a vital question.
question 是名词，需要形容词修饰；vitally 是副词，不能直接放在名词前，应改为形容词 vital。中文的“至关重要的问题”中“至关重要”修饰名词，因此用形容词而非副词。

记忆联想：vital 是“生命的”，关乎生命的事自然极其重要，故 vitally 意为“紧要地”。
语域：formal 常见场景：academic writing、news reporting、formal speech 表示“极其重要地”时，vitally 通常用于较正式的书面或讲话场合，常见搭配如 vitally important，日常口语中较少使用。
注：lightly、brightly、rightly、slightly、tightly 与 vitally（/ˈvaɪtli/）押韵，均以 /aɪtli/ 结尾。vital 拼写相近，但读作 /ˈvaɪtəl/，并不押韵，注意区分。
