Learn to express alternatives and possibilities with “if not A, then B” and extended patterns in Mandarin Chinese
AB Basic Pattern: 不是…就是…
The pattern 不是…就是… means “If it’s not A, then it’s B” or “Either A or B”. It presents two alternatives, suggesting that one of them must be true.
Logical Flow
If not A, then definitely B (and vice versa)
Example Sentences

Describing limited options or habits:
ABC Extended Pattern: 不是…就是…要不然就是…
The extended pattern 不是…就是…要不然就是… means “If it’s not A, then it’s B, otherwise it’s C”. This structure presents three possibilities instead of just two.
Three-Possibility Flow
If not A, then if not B, then definitely C
Example Dialogues
Key Component: 要不然 (yàobùrán)
要不然 (yàobùrán) means “otherwise” or “or else”. In this pattern, it introduces the third (and usually final) alternative.
The full phrase 要不然就是 can be thought of as “or otherwise it’s” or “if neither of those, then it’s”.
Pattern Comparison & Usage
Understanding when to use the basic vs. extended pattern depends on how many alternatives you want to present and the context of your statement.
Basic Pattern: 不是…就是…
- Number of options: Two
- Certainty level: High (must be one of these two)
- Typical use: Limited choices, binary situations
- English equivalent: “Either A or B”
- Example: 他不是在工作，就是在学习。
(He’s either working or studying.)
Extended Pattern: 不是…就是…要不然就是…
- Number of options: Three
- Certainty level: Still high, but with more possibilities
- Typical use: Multiple common alternatives, habitual activities
- English equivalent: “Either A, or B, or otherwise C”
- Example: 我不是喝茶，就是喝咖啡，要不然就是喝水。
(I either drink tea, or coffee, or otherwise water.)
Usage Guidelines
Use the basic pattern (不是…就是…):
- When there are only two likely possibilities
- When you want to emphasize a binary choice
- When the situation naturally suggests only two options
Use the extended pattern (不是…就是…要不然就是…):
- When there are three common possibilities
- When describing habitual activities with multiple variations
- When you want to sound more comprehensive or detailed
