题目

What good is that gonna do anybody?
Joey:(in a bored voice) PBS telethon.
Phoebe:(on phone from Central Perk) Hey Joey,I just wanted to let you know that I found a selfless good deed：I just went down to the park and I let a bee sting me.
Joey:What?What good is that gonna do anybody?
Phoebe:Well,it helps the bee look tough in front of his bee friends.The bee is happy and I am definitely not.
这个是原文 What good is that gonna do anybody我明白是什么意思
但是我就是不明白 这句话是怎么构成的 语法怎么用的?

答案

Good 在这里是名词,指 好处,利益.do good to sb.对 xxx 有好处Phoebe 觉得被蜜蜂叮了一下是做了件无私的大好事.Joey 觉得很不可思议,所以就问了句,What good is that gonna do (to) anybody?这种行为对人有什么好处...
