是非问句
是非问句是提出问题，要求别人回答“是”或“否”的疑问句。是非问句与一般陈述句的结构形式基本相同，但语调要变为疑问调，或者句末加上疑问语气词。是非问句中经常使用的疑问语气词有“吗、吧、啊”等，但不能使用“呢”。
特指问句

选择问句是提出两种或两种以上的情况，让对方从中进行选择的疑问句。选择问句经常使用“A还是B”、“是A还是B”等固有格式，选择疑问句全句用or连接。朗读时or前的部分升调or后的部分用降调。使用疑问词时，选择问句常用“呢”，一般不用“吗、啊、吧”。
正反问句
正反问句使用肯定和否定叠和的方式进行提问，希望对方从肯定和否定的内容中做出选择的疑问句。正反问句一般不使用疑问代词或疑问语气词。需要时可用“呢、啊”，一般不用“吗、吧”。
In Chinese, interrogative sentences are generally classified in the following four ways:
Right or wrong question
Right-and-fee questions are questions that ask others to answer “yes” or “no”. The structural form of the right and wrong question is basically the same as that of the general declarative sentence, but the intonation should be changed to an interrogative tone, or interrogative particles should be added at the end of the sentence. Interrogative particles often used in right and wrong questions include “?, bar, ah”, etc., but “N” cannot be used.
Specific question
The specific question is a question that uses interrogative pronouns to replace the unknown part to ask questions and ask the other party to answer the unknown part. The specific question sentence can use either the interrogative tone or the exclamation tone. In particular, the question sentence can only use modal particles such as “ne, ah”, and cannot use “ma, bar”.
Choice question
Choice question is a question sentence that proposes two or more situations for the other party to choose from. Select question sentences often use inherent formats such as “A or B”, “A or B”, etc., and select the whole sentence with or to connect. When reading aloud, the part before or rises or the part after it is reduced. When using interrogative words, you often choose “N” in the question sentence, and generally don’t use “Ma, ah, bar”.
Positive and negative question
Positive and negative questions are used to ask questions in a way of overlapping affirmations and negatives, and the other side is expected to choose between positive and negative content. Interrogative pronouns or interrogative particles are generally not used in positive and negative questions. You can use “Nah, ah” when you need it, but generally don’t use “Why, right”.
