英语翻译:谁是最健康的学生

Who is most healthy student?
healthy的最高级前加most，部分双音节单词，前加most，部分加-est后缀。因为healthy是变形后的，非词根单词（词根是health），所以要前面加most作为最高级，加more作为比较级。同理还有useful等。

Who is the healthiest student?healthy的比较级是healthiest

我觉得都能用,口语是随便说的

Who is most healthy student?

who is the healthist student ?

who is the healthiest student?
