couldn't care less 字面意思是“不能关心更少”，转换成肯定句就是”关心更多“，但实际上它的意思恰恰与之相反，couldn't care less 表示一点也不关心，相当于 don't care at all，可以意为“毫不在乎，漠不关心”，表达：
total lack of interest in something
对某事完全不感兴趣
do not care at all
一点也不在乎
utterly indifferent to something
对某事漠不关心
例如：
I have heard that my ex is going through another break-up, but I couldn't care less.
我听说我的前男友又要分手了，但我不在乎。
解析：短语动词 go through 在这里意为“经历，经受”，通常是苦难或困难时期。
The win was marred in controversy, but the jubilant fans couldn't care less.
这场胜利在争议中被破坏了，但欢呼雀跃的球迷们却毫不在乎。
Tom came up with his sob story, expecting me to show him sympathy, but I couldn't care less.
汤姆想出了一个可悲的故事，希望我能对他表示同情，但我一点也不在乎。
解析：现在分词 expecting me to show him sympathy 作状语。
He couldn't care less that his neighbours were moving. He was not on very good terms with them.
他对邻居搬家毫不在乎。他和他们关系不太好。
解析：be on good terms with sb 表示与某人相处很好。
