"It's a thousand to one against our finding him at the house," he continued as we retraced our steps swiftly down the path. "Those shots must have told him that the game was up."
请教老师:为什么这句话的意思是“要想在室内抓住他,可能性微乎其微” 。
a thousand to one 的意思是“千对一,几乎绝对的,几乎可以肯定” ,那么如何理解这里的against呢? 如果把这里的against换成about或on意思一样吗?
