一旦⋯⋯，就⋯⋯

Once..., then...

Explanation

The structure '一旦⋯⋯，就⋯⋯' is used to describe a condition that is likely to occur in the future, and as soon as that condition happens, the result will follow immediately. It emphasizes the swiftness or inevitability of the result. For example: 'Once I fail the exam, then I will have to postpone graduation.' This structure often carries a hypothetical nuance, emphasizing a near-certain cause-and-effect relationship.
