易错句子I frightened of big dogs.
正确表达I am frightened of big dogs.
汉语形容词可以直接作谓语（“我害怕大狗”不用“是”），但英语形容词作谓语时必须与 be 动词连用；frightened 是形容词，所以要说 am frightened，不能单独使用 frightened。

易错句子She was frighten by the loud noise.
正确表达She was frightened by the loud noise.
frighten 是动词原形，不能直接放在 be 动词后表示状态；表示“感到害怕的”要用形容词 frightened（由过去分词转化而来），因此 was 后应为 frightened。

正确表达He felt very frightened when he walked into the dark room.
修饰人的感受时用 -ed 形容词 frightened，表示“人感到害怕”；-ing 形容词 frightening 表示“令人害怕的”，主语通常是引起恐惧的事物。这里主语 he 是感受者，所以用 frightened。

与 frightened 相对，强调毫无恐惧
与 frightened 相对，指面对恐惧时表现勇敢
与 frightened 直接相反，未受惊吓
与 frightened 相对，指敢于冒险不害怕
afraid 通常只作表语（如 be afraid of），不能放在名词前；frightened 既可作表语也可作定语，如 a frightened child。
scared 更偏口语，常与 of 或 to do 连用；frightened 更中性，且常用于定语位置，如 a frightened animal。
frightening 表示“使人感到害怕的”，主语通常是事物；frightened 表示“自身感到害怕的”，主语通常是人。
