perseverance(急)

She is perseverance. ~ 錯

perseverance 是 abstract noun (抽象名詞), 不能這樣使用

其他的例子
She is happiness. ~ 錯 (happiness 是 abstract noun )
She is happy. ~ 對, 要用 adjective (形容詞)

She is kindness. ~ 錯 (kindness 是 abstract noun )
She is kind. ~ 對, 要用 adjective

happy 和 kind 是 adjectives

問題 perseverance 沒有同等形容詞, 動詞是 persevere (verb)
persevering 是 present participle (現在分詞), 可作形容詞, 用在 noun 前
面..現在分詞是 verb + ing
e.g. a persevering student

你的句子改為:
She has perseverance. 她有毅力
She shows perseverance. 她顯出有毅力
She displays perseverance. 她表現有毅力
She is a woman of perseverance. 她是一個有毅力女人
She is a persevering woman.
