可以,行,好
used to say that you can and will do something
"Will you mail this letter for me, please?" "Can do." “请你帮我把这封信寄了,好吗?”“行。”
"I need you to pick up the kids today." "Sorry, no can do (= no I can't)." “今天我需要你去接孩子。”“抱歉,不行。”
"Could you give these to Paola, please?" "Can do."
She shook her head. "Sorry, no can do."
I asked for an earlier appointment but no can do.
