apology道歉: 为错误失误遗憾，承认罪责过错，无论是否提到可使罪责减轻的情况(extenuatingcircumstances)，apologia辩解: 不是承认过错，而是讲清某过程想法立场的根据，excuse开脱或原谅: 希望免受责备谴责，plea请求: 强调为得到理解同情怜悯(understanding,sympathy,mercy) 而进行的论证请求(argument,appeal)，pretext借口: 表示欺骗手段(subterfuge欺骗==deceit)，为开脱解释给出虚假原因或目的，alibi也是借口: 希望转移责任逃脱惩罚，表示似是而非不真实(plausible有两个意思: 1似乎有道理，2花言巧语，这里采用第2个)。
