Replace the missing information in its own position
Start from the kind of statement you expect as an answer. If the answer is 我喝茶, the unknown drink can be replaced with 什么: 你喝什么. The question changes the perspective from I to you and replaces the drink with the question word. It does not move 什么 to the beginning merely because English says “what do you drink.” This method lets the familiar statement structure guide the question.
The question word’s position depends on its role. In 谁喝茶, the unknown person performs the action, so 谁 occupies the subject position. In 你喝什么, the unknown thing is the object. It would therefore be misleading to memorize a rule that all Mandarin question words belong at the end. They stay where the relevant missing information is expressed in the ordinary pattern.
These are information questions, which ask the listener to supply a person, thing, place, time or another missing detail. A 吗 question instead checks a proposed statement. The ordinary information question does not need an additional 吗. More advanced uses of question words can express indefiniteness or other meanings, but they are outside this starting pattern. Learn the clear ordinary contrast first, then add those uses with their own context.
你喝什么?
Nǐ hē shénme?
What do you drink?
谁喝茶?
Shéi hē chá?
Who drinks tea?
你喝茶吗?
Nǐ hē chá ma?
Do you drink tea?
Ask for the unknown drink
The expected answer is “I drink tea.” Ask what the other person drinks.
- Change the speaker perspective from 我 to 你.
- Keep 喝 as the predicate.
- Replace the unknown object with 什么 in its object position.
你喝什么?
Distinguish who from whose
谁 asks for a person. 她是谁 asks who she is, while 谁是老师 asks who is a teacher. The unknown person has a different role in the two questions, but the word remains useful in both. A reply may provide a name, a relationship or a role when that is what identifies the person in the current conversation. The course uses the common reading shéi. You may also encounter shuí in dictionaries and careful speech; recognizing a pronunciation variant does not require changing the sentence’s grammar.
To ask about ownership, use 谁的 before the relevant noun in the basic possession phrase. 这是谁的书 asks whose book this is. The unknown information is the owner, not the identity of the book as an object. A reply such as 这是我的书 fills the owner phrase with 我的. It can also be shortened when the item is already clear, but a complete reply helps a beginner see the relation.
Do not treat 谁 and 谁的 as interchangeable translations of a vague English question about a person. “Who is she?” asks for identity. “Whose book is this?” asks which person has the ownership or association relation. The distinction matters because the answer must provide the correct kind of information. A person’s name may occur in both replies, but the grammatical phrase around that name expresses a different relationship.
她是谁?
Tā shì shéi?
Who is she?
谁是老师?
Shéi shì lǎoshī?
Who is a teacher?
这是谁的书?
Zhè shì shéi de shū?
Whose book is this?
Keep where with the location or destination
哪里 and 哪儿 both ask where. For a person’s current location, use a pattern such as 你在哪里. For the destination of going, use 你去哪里. 在 and 去 do different work: one locates the person, and the other describes movement toward a destination. The question word follows the relevant predicate in these simple examples because that is where the unknown place belongs.
The answer should preserve that distinction. 我在学校 says where you are. 我去学校 says where you go or are going, according to context. Someone who is going to school may still be at home when they answer. A destination is not proof of current location. This practical difference is why the questions cannot be treated as interchangeable even though both translate into English with “where.”
You can use the 儿 forms in the same basic roles: 你在哪儿 and 你去哪儿. The two sets are common Mandarin choices with regional and stylistic preferences. Do not combine every form into a longer invented word or add 吗 to the ordinary information question. Choose one form for your own initial production, recognize the other, and focus on whether you need a current place or a destination.
你在哪里?
Nǐ zài nǎli?
Where are you?
你去哪里?
Nǐ qù nǎli?
Where are you going?
你去哪儿?
Nǐ qù nǎr?
Where are you going?
Choose location or destination
Ask where a friend is now, then ask where they are going.
- For current location, use 在 with the unknown place.
- For a destination, use 去 with the unknown place.
- Do not add 吗 to either ordinary information question.
Compare your reasoning
你在哪里? / 你去哪里?
Ask when at the level of detail you need
什么时候 asks when in a general sense. 你什么时候去 can receive a day, a period or a clock time, depending on the context. 几点 more specifically asks for a time on the clock. 你几点去 therefore requests the departure hour. The question expressions occur before the main verb, where an ordinary time occasion would appear in the corresponding statement.
If the day is already established, a clock question can be concise. After agreeing on tomorrow, asking 明天几点去 narrows the remaining uncertainty to the hour. If the day is not established, 三点 alone may still leave the arrangement unclear. Good grammar does not remove the need to include enough practical information. Add the day and part of day when they matter to the plan.
Other time questions target different units. 星期几 asks which day of the week, and 几月 asks which month. These are useful expressions, but they are not all replacements for 什么时候 in every context. Learn what type of answer each one invites. Also keep time of occurrence separate from duration: a question requesting an hour on the clock should not be answered only with “two hours,” which measures elapsed time rather than locating the event.
你什么时候去?
Nǐ shénme shíhou qù?
When will you go?
你几点去?
Nǐ jǐ diǎn qù?
What time will you go?
今天星期几?
Jīntiān xīngqī jǐ?
What day of the week is it today?

Use classifiers in choices and quantities
哪 asks which item within a relevant set. With a counted noun, the basic phrase includes the appropriate classifier: 哪本书 asks which book, and 哪个学生 asks which student. 我看哪本书 is a question about the book to read, while 你喜欢哪本书 asks which book the listener likes. The set may be visible or already established in the conversation; you need not name every possible option inside the question.
几 and 多少 ask about quantity. 几 commonly fits an expected relatively small number and is followed by a classifier in ordinary noun counting phrases, such as 几本书. 多少 works more broadly and can occur without a classifier in many such questions. Do not turn the small number tendency into a strict arithmetic law that makes every larger answer impossible. Use the expected context and learn familiar complete expressions.
多少钱 asks how much money something costs. 这本书多少钱 is therefore a price question, not a question about the number of books. The presence of 钱 changes the information requested. This is another reason to read the whole phrase instead of matching one question word to one English gloss. A correct answer needs to supply the selected item, the quantity, or the price that the question actually seeks.
你喜欢哪本书?
Nǐ xǐhuan nǎ běn shū?
Which book do you like?
你有几本书?
Nǐ yǒu jǐ běn shū?
How many books do you have?
这本书多少钱?
Zhè běn shū duōshao qián?
How much does this book cost?

Distinguish why, how and an evaluation
为什么 asks for a reason. 你为什么不去 asks why the listener is not going. A reply can use 因为 to introduce a reason, such as 因为我很忙. The answer explains the decision or situation instead of merely repeating that the person is not going. This is a different task from identifying a destination or a departure time, even when all the questions concern the same planned trip.
怎么 often asks about method: 你怎么去学校 can ask how the listener gets to school. A reply such as 我走路去 supplies a way of traveling. However, 怎么 can also convey a why or how come meaning in context, sometimes with surprise or a challenging tone. It would be too broad to say that it always asks for transportation or procedure. Learn the method question in a clear context before interpreting more expressive uses.
怎么样 asks how something is or invites an evaluation. 这本书怎么样 asks what the book is like or how the listener finds it. 很好 can answer that evaluation. The similar looking question words are not interchangeable. First decide whether you want a reason, a method or an assessment, then choose the phrase that asks for it. The examples and questions specify that intention so that there is a meaningful basis for the choice.
你为什么不去?
Nǐ wèishénme bù qù?
Why are you not going?
你怎么去学校?
Nǐ zěnme qù xuéxiào?
How do you get to school?
这本书怎么样?
Zhè běn shū zěnmeyàng?
What do you think of this book?

Make the reply fill the actual gap
A well formed question still needs a relevant answer. To 你喝什么, 茶 can be enough if the context is clear. To 你在哪里, a place such as 在家 supplies the missing information. To 这是谁的书, 我的 identifies the owner. These short replies are possible because the question already provides the rest of the structure. They are not evidence that full sentences are unnecessary in every new context.
A yes or no answer alone usually does not fill an ordinary information gap. If someone asks where your book is, simply saying 是 does not provide its location. If someone asks which book you want, answering with a price may be true but irrelevant. Pay attention to the kind of information requested instead of treating all question marks as invitations to choose a generic affirmative or negative response.
For practice, begin with three true or imagined statements. Remove one different kind of information from each, build the matching question, and then answer it. Check the position of the question phrase and whether the ordinary pattern needs 吗. Finally change the missing information while keeping the rest of the topic constant. Asking where, when and why someone goes to school reveals how each question organizes a different part of the same event.
茶。
Chá.
Tea.
在家。
Zài jiā.
At home.
我的。
Wǒ de.
Mine.
Notice the difference
Common mistakes
Do not copy English fronting
Instead of什么你喝?
For this meaning你喝什么?
The unknown drink occupies the ordinary object position.
Do not add 吗 to the ordinary information question
Instead of你在哪里吗?
For this meaning你在哪里?
哪里 already requests the missing place.
Keep the classifier in the choice phrase
Instead of你喜欢哪书?
For this meaning你喜欢哪本书?
The ordinary which book phrase uses 本 between 哪 and 书.
Distinguish owner from person identity
Instead of这是谁书?
For this meaning这是谁的书?
谁的 forms the owner phrase before the book noun.
From understanding to using
Make your own example.
Try these without answer choices. Say your answer aloud or write it below, then compare your reasoning with the model.
Your turn 1
Ask whose book this is, then answer as its owner.
Compare with a model
这是谁的书?这是我的书。 (Zhè shì shéi de shū? Zhè shì wǒ de shū.)
Whose book is this? This is my book.
谁的 requests the owner and 我的 fills that possession phrase in the answer.
- Keep 的 with the owner phrase.
- Answer ownership rather than the book’s price.
Your turn 2
Ask when the listener will go to school, then separately ask why they are not going today.
Compare with a model
你什么时候去学校?你今天为什么不去? (Nǐ shénme shíhou qù xuéxiào? Nǐ jīntiān wèishénme bù qù?)
When will you go to school? Why are you not going today?
The first question requests a time; the second requests a reason for the stated nonattendance today.
- Keep the question expressions before the main action.
- Do not append 吗 to these ordinary information questions.
