My hands are tied 我无能为力
A: Mr. Chapman, can I hand in my homework next time. I left it at home.
A: Chapman 先生, 我能不能下次再交作业呢? 我把功课忘在家里了。
B: All of the scores must be given to the office by Friday, so you must have your homework today. It is a school rule and there is nothing I can do. My hands are tied!.
B: 所有的分数都必须在礼拜五前交到办公室(学校), 所以你今天一定要有你的作业。这是学校的规定, 我无能为力。
"My hands are tied." 在这里并不是真正「手被绑起来」的意思, 而是指「没办法」的意思。好比电话响了, 你很忙不能接, 也可以说:"Can you get it? My hand are tied." (我很忙, 你能接一下吗?" 。
