There was nothing to_____so.中间填 keep her from doing 还是 prevent her doing 讲下理由.
答
keep her from doing
prevent her doing 中间要加 from
答
两者皆可：keep her from doing =prevent her（from） doing
keep sb from doing =prevent sb（from） doing = stop sb（ from） doing
请注意：三者均表示 “阻止某人做某事”,但后两个词组可以省去 from 而不影响 意义的表达,但keep sb from doing中from不可省略,因为 keep sb doing 意思是“使某人不断做某事”.
