核心句型：
I was going to ask my boss for a raise but I got cold feet.
我打算要求老板给我加薪，但我退缩了。
got cold feet直译过来就是：“双脚变冷”，这个短语的正确意思是：“失去勇气，临阵退缩”。因此，当美国人说"I was going to ask my boss for a raise but I got cold feet."时，他/她要表达的意思就是:"I wanted a pay rise from my boss but I dared not to."、"I gave up asking my boss a salary raise."。
