How it works
Introduces a rhetorical question that expresses disbelief or challenges an idea; the speaker actually implies the opposite of what is asked. It usually ends with 吗 and is not meant to be answered literally.
Examples
难道你不知道今天有考试吗?
Nándào nǐ bù zhīdào jīntiān yǒu kǎoshì ma?
Don't tell me you didn't know there's a test today?
难道这就是你的答案?
Nándào zhè jiùshì nǐ de dá'àn?
Could this really be your answer?
