Conditional Expressions in Chinese: 幸亏⋯⋯ ，要不然/不然/要不/否则⋯⋯

The phrase 幸亏 (xìngkuī) translates to "fortunately" or "thankfully" and is used to express relief or gratitude that a certain situation turned out positively. It is often followed by a conditional phrase that indicates what would have happened if the fortunate circumstance had not occurred.

The expressions 要不然 (yàobùrán), 不然 (bùrán), 要不 (yàobù), and 否则 (fǒuzé) all serve a similar purpose: they introduce a consequence or an alternative scenario that would occur if the preceding condition were not met.

Structure:

• 幸亏 + [positive situation], + 要不然/不然/要不/否则 + [negative consequence].

Examples:

1. 幸亏你提醒了我，要不然我就忘了。

2. "Fortunately, you reminded me; otherwise, I would have forgotten."

3. 幸亏有你帮忙，不然我真不知道怎么办才好。

4. "Fortunately, you helped me; otherwise, I really wouldn't know what to do."

In these examples, 幸亏 sets up a positive context, while the following phrases indicate the negative outcomes that would have occurred without that positive context. This structure is useful for expressing gratitude and highlighting the importance of certain actions or events in avoiding undesirable situations.
