Language/Mandarin-chinese/Grammar/Questions-with-不-(bù)

Closed interrogative questions in Chinese can also be formulated with 不 (bù).

This is done by adding an affirmative-negative structure at the end of the sentence.

Structure

Verb + 不 + Verb

好 不 好 ？

對 不 對 ？/对 不 对 ？

是 不 是 ？

When placed before a falling tone character, 不 is read bú.

This expression can be attached to the end of a sentence to form a closed interrogative sentence.

Closed interrogative sentences await confirmation or acceptance of what has been said.

In English "isn't it?" or "OK?" are often used for closed interrogative sentences.  

Examples

• 他們 來 不 來 ？/他们 来 不 来 ？ (Tāmen lái bù lái?)

Are they going to come or not?

• 你 想 不 想 我 ？ (Nǐ xiǎng bù xiǎng wǒ?)

Do you or do you not miss me?

• 我們 要 去 酒吧 ， 你 去 不 去 ？/我们 要 去 酒吧 ， 你 去 不 去？ (Wǒmen yào qù jiǔbā, nǐ qù bú qù?)
