a day late and a dollar short

“晚了一天，少了一美元”？其实它的意思是“差一点点，差一步”，即某件事发生得有点太晚，不足以接受。

They offered me a contract after I'd already accepted another job offer – a day late and a dollar short!

在我接受了另一份工作之后，他们给了我一份合同——就差一点点！

two-time

“two-time”不是两次！千万不要弄错了，它真正的意思是“背叛自己的另一半，对爱情不忠”。

When she found out that he had been two-timing her, she left him instantly.

当她发现他背叛她时，她立即离开了他。
