Though I am a green hand. I'm completely at grips with the details of my job.
我虽然是个新人，但完全了解工作的方方面面。
a green hand直译过来就是：“一个绿色的、尚未成熟的手”，这个短语的正确意思是：“新人，新手，无经验的人”。因此，当美国人说"Though I am a green hand, I'm completely at grips with the details of my job."时，他/她要表达的意思就是:"I can deal well with my work though I am a newcomer."、"I have a good command of my work though I have no experience."。
