Choice-type questions ask people to decide between taking and not taking an action. No specific question words are needed. The format of the question is verb 不 verb , but it has the following two variations.
你 是 不 是 学生
Are you a student? (lit. you are not are student)
你 是 学生 不 是
Are you a student? (lit. you are student not are )
If a bi-syllabic verb (A and B) is used, there are three ways to form the questions.
你 认识 不 认识 他
Do you know him? (lit. you recognise not recognise him)
你 认识 他 不 认识
Do you know him? (lit. you recognise him not recognise)
你 认 不 认识 他
Do you know him?
