常见误用提醒
使用 resolute：He is very resolute to finish the task. → He is very resolute in finishing the task. (错误在于使用了“to”不定式，而“resolute”通常与介词“in”搭配，后接动名词或名词，表示在某个方面坚决。应改为“resolute in finishing the task”。)
使用 resolute：She made a resolute decide to move abroad. → She made a resolute decision to move abroad. (错误在于使用了动词“decide”作为名词，而“resolute”作为形容词应修饰名词“decision”。应改为“resolute decision”，确保语法正确。)
使用 steadfast：He is very steadfast to his plan. → He is steadfast in his plan. (错误在于介词使用不当，steadfast 通常与 in 搭配表示在某个方面坚定，而不是 to。)
