The middle-aged man dennied having been there.为何要用having been?

有些动词后跟非谓语动词时,非谓语动词只用动名词(doing/being done).如:avoid,finish,allow,permit等.而有些既可用doing,也可用having done,二者没有区别.如: regret,remember,forget,deny等.如:I regret telling/having told him the secret.

完整的句子是：The middle-aged man dennied (that he was) having been there. 括号内的内容可以省略。
