Today, I would " bet my bottom dollar" that my friend will never gamble again -- I would bet all I have that he learned his lesson about gambling.

今天，我敢打赌(bet my bottom dollar)，我的朋友肯定不会再赌博。我敢打赌，他一定从赌博中得到了教训。

" Ah" ! said Stonor. " I get you now. But I'll bet my bottom dollar that you're wrong. The old man never so much as looked at a petticoat. He just adored his own wife. They were the most devoted couple I know" .

“啊”！斯托纳说。 “我现在明白你的意思了。但我敢打赌你错了。那个老人从来没有看过一件衬裙。他只是崇拜他自己的妻子。他们是我所知道的最忠诚的夫妻。”
