易错句子I am regret about my choice.
正确表达I feel regret about my choice.
regret 在这里是名词，不能像形容词那样跟在 be 后面作表语。汉语"我很后悔"不能直译成 I am regret，而要用动词 feel / have 加名词 regret，如 feel regret about sth；若想说"感到后悔的"，则用形容词 regretful。

正确表达He has many regrets about his youth.
regret 作可数名词指一件件具体的"遗憾、悔恨"时要用复数形式；many 只能修饰可数名词复数，所以不能说 many regret，必须说 many regrets。
