Meaning

Rhetorical questions in Chinese use patterns like 能……吗, 不是……吗, and 怎么会……呢 to make a statement disguised as a question. The speaker does not expect an answer — the 'question' emphasizes an obvious point.

Chinese has several common rhetorical question patterns, each with a distinct flavour. 能……吗？ implies 'of course you can't' (你能不吃饭吗？— Can you just not eat?). 不是……吗？ reminds someone of a fact they should already know (你不是答应了吗？— Didn't you promise?). 怎么会……呢？ expresses that something is impossible or very unlikely (他怎么会不知道呢？— How could he not know?). These patterns are powerful persuasion tools in spoken Chinese and are much more common than in English. The tone is often gently scolding, reminding, or expressing disbelief. Unlike genuine questions, rhetorical questions typically carry falling intonation and the speaker continues talking without waiting for a response.

Examples

1. 你不是说过要来吗？怎么又不来了？ Didn't you say you were coming? How come you're not coming again?
2. 这种事能随便答应吗？ Can you just agree to this kind of thing casually?
3. 他怎么会忘记自己的生日呢？ How could he forget his own birthday?
