第一，迷你对话
A: Do you think you can pass the final exam?
你觉得你可以通过期末考试吗？
B: There is only an outside chance.
机会微乎其微。
第二，地道表达
an outside chance
1. 解词释义
Outside做形容词时，有“极微的，几乎不可能的”的意思。那么an outside chance的意思则是“极其微小的希望”“一线希望”。
2. 拓展范例
E.g. There's an outside chance that he may come today.
今天他不大可能会来。
E.g. They had an outside chance of winning the game.
他们有微乎其微的获胜可能。
E.g. There is an outside chance of saving the patient.
救活那位病人的希渺茫。
