Question 1
Li Ming is talking about his daily routine. He says: '我每天都喝咖啡,但是今天我 喝咖啡。我喝了茶。'
Which negation word correctly completes Li Ming's sentence to indicate that he did NOT drink coffee today (a completed action in the past)?
- 不 (bù) — because 不 is used to negate all actions regardless of time
- 没 (méi) — because 没 negates completed or past actions and states (correct answer)
- 别 (bié) — because 别 expresses that the action did not happen today
- 不是 (bù shì) — because 不是 negates the identity of the beverage he drank
Explanation: When negating actions in Mandarin, the most important distinction to master is whether the action was completed in the past or is simply a matter of habitual preference or future intention. This question tests exactly that distinction.
Li Ming's sentence establishes that drinking coffee is his daily habit, but then contrasts it with today specifically — where the drinking action either happened or didn't. Since he follows up with "I drank tea" (我喝了茶), we know today's events are being described as completed past actions. The correct word here is 没 (méi), making option B right. 没 is specifically used to negate completed or past actions, essentially meaning "did not" for something that could have occurred but didn't. The sentence reads: "today I did not drink coffee" — a factual statement about a past event.
Option A is tempting because 不 (bù) is the most common negation word, but it negates habitual behavior, preferences, or future intentions — not past events. Saying 不喝咖啡 would imply "I don't drink coffee" as a general preference, which contradicts his established habit. Option C, 别 (bié), is a negation used for commands or suggestions — telling someone not to do something. It cannot describe what someone did or didn't do in the past. Option D, 不是 (bù shì), negates the verb "to be" (是) and would only make sense if Li Ming were denying an identity or classification, not an action.
A reliable memory tip: think of 没 = "did not" (past facts) and 不 = "don't/won't" (habits or preferences). Whenever you see a past completed event being negated, 没 is almost always your answer.
Question 2
Wang Fang is telling her friend: '你 说话!老师在讲课。' (You talk! The teacher is giving a lecture.)
Wang Fang is giving her friend a command not to talk. Which negation word best completes her sentence?
- 不 (bù) — because 不 is the most common negation word in Mandarin
- 没 (méi) — because 没 negates actions that are happening right now
- 别 (bié) — because 别 is used to give negative commands or prohibitions (correct answer)
- 不是 (bù shì) — because 不是 negates the situation of talking in class
Explanation: When you see a question asking you to fill in a negation word in Mandarin, your first step should be identifying the function of the negation — is the speaker stating a fact, describing a past action, or issuing a command? That distinction determines everything.
Here, Wang Fang is telling her friend to stop or not do something — she's giving a negative command (prohibition). This is precisely the role of 别 (bié), making C the correct answer. 别 is the standard word used to tell someone not to do something, equivalent to "don't" in English commands. The sentence 你别说话!means "Don't talk!" — direct, natural, and grammatically correct.
The other choices reflect common misconceptions worth understanding. A is wrong because 不 (bù) negates general habits, intentions, or states (e.g., 我不喜欢 — "I don't like"), not imperative commands. Using 不说话 here would sound like a statement of fact rather than a command. B is wrong because 没 (méi) negates completed actions or possession (e.g., 我没吃饭 — "I haven't eaten"), so it's tied to past events or existence — not prohibitions. D is wrong because 不是 (bù shì) specifically negates the verb 是 ("to be"), used for identity or classification. It has no grammatical role in commanding someone to stop an action.
A handy study tip: associate 别 = "don't!" (commands), 不 = "don't/doesn't" (habits/facts), and 没 = "didn't/haven't" (past/completed). Keeping these three negators clearly separated will serve you throughout the entire course.
Question 3
Read the following short dialogue:
A: 你昨天去图书馆了吗?(Did you go to the library yesterday?)
B: 我 去图书馆,我在家里学习。(I go to the library; I studied at home.)
Based on the dialogue, which negation word should fill in the blank in Speaker B's response to correctly indicate that the action of going to the library did not occur yesterday?
- 不 (bù) — to indicate that going to the library is generally not something B does
- 没 (méi) — to indicate the specific past action of going did not take place (correct answer)
- 别 (bié) — to express that B chose not to follow through on going
- 不要 (bù yào) — to express that B did not want to go to the library
Explanation: When negating actions in Mandarin, the most important distinction to master is 不 (bù) vs. 没 (méi). Ask yourself: are you talking about a general habit or preference, or a specific completed (or non-completed) action in time? That question unlocks this entire category of problems.
Here, Speaker B is responding about something that did or didn't happen yesterday — a specific point in the past. This is precisely where 没 (méi) belongs. It negates actions in relation to a specific moment or time frame, indicating the action simply did not take place. So "我没去图书馆" correctly means "I did not go to the library (on that occasion)," which perfectly fits the context. B is correct.
Choice A, 不 (bù), negates habits, preferences, or present/future intentions — not past occurrences. Saying "我不去图书馆" implies "I generally don't go to the library" or "I'm not going," which misrepresents the situation and ignores the time marker 昨天 (yesterday). Choice C, 别 (bié), is used for commands or suggestions — telling someone else not to do something (e.g., "别说话!" = "Don't talk!"). It cannot describe what the speaker themselves did or didn't do. Choice D, 不要 (bù yào), expresses unwillingness or is used in prohibitions, similar to 别. It conveys "don't want to" or "don't," not a factual negation of a past event.
Your study tip: whenever you see a past time word like 昨天, 上周, or 已经, default to 没 for negation. Time markers are your signal that 不 is almost certainly wrong.
Question 4
A student writes: '他不是学生,他是老师。' (He is not a student; he is a teacher.) Which negation word is used, and why is it the correct choice?
- 不 (bù) — it negates the verb 是 (to be) to deny an identity or categorization, which is its standard function with 是. (correct answer)
- 没 (méi) — it negates 是 when discussing a person's role or status in context.
- 别 (bié) — it is used here to instruct others not to call him a student.
- 不要 (bù yào) — it expresses that the subject does not want to be identified as a student.
Explanation: When tackling negation questions in Mandarin, your first step is to identify what kind of statement is being negated — is it a state of being, a completed action, or a command? This distinction determines which negation word belongs.
In the sentence '他不是学生,他是老师,' the verb 是 expresses identity or categorization — what someone is. The negation word 不 (bù) is the correct choice here because it negates states, habitual actions, and the verb 是 specifically. It tells us the identity claim is simply untrue: he is not a student. Answer A is correct.
Answer B is wrong because 没 (méi) negates completed actions or possession — it pairs with verbs like 有 (to have) or action verbs in the past tense. You would say 他没吃饭 (he didn't eat), not use 没 with 是 to describe identity. Using 没是 is grammatically incorrect in standard Mandarin.
Answer C is wrong because 别 (bié) is an imperative negation used to tell someone not to do something, as in 别走 (don't leave). It addresses a second person and issues a prohibition — it has nothing to do with describing a third person's identity.
Answer D is wrong because 不要 (bù yào) similarly carries an imperative or volitional meaning — "don't" or "don't want to." It implies desire or instruction, not a simple factual denial of identity.
A handy rule of thumb: if you're denying a fact about what something is, reach for 不. Save 没 for actions and possession, and 别/不要 for commands.
Question 5
Zhang Wei says: '我 有时间,所以我 去参加派对。' (I have time, so I go to the party.) He is describing his current general situation — he has no free time — and therefore will not attend the party.
Which pair of negation words correctly fills in both blanks in Zhang Wei's statement?
- 没 / 不 — because 没有 negates possession of time, and 不 negates the future/intended action (correct answer)
- 不 / 没 — because 不 negates the state of having time, and 没 negates the future action
- 别 / 不 — because 别 negates possession and 不 negates the planned action of attending
- 没 / 别 — because 没有 negates possession and 别 negates the future intention to attend
Explanation: When you see negation questions in Mandarin, your first step is to identify what kind of thing is being negated — a possession/existence, a habitual state, or a command. Each negation word has a specific job, and mixing them up is the most common mistake learners make.
In Zhang Wei's sentence, the first blank negates having time — a possession or existence. In Mandarin, 没 (méi) is the word used to negate possession and existence, typically paired with 有 to form 没有. The second blank negates a voluntary, intentional action — his decision not to go to the party. For negating future intentions, plans, or general habits, 不 (bù) is correct. So the sentence reads: 我没有时间,所以我不去参加派对 — "I don't have time, so I won't go to the party." That makes A the correct answer.
B swaps the two words entirely. 不有时间 is grammatically wrong — 不 cannot negate 有 when expressing possession. 没 doesn't negate intentional future actions.
C uses 别 (bié) in the first blank, which is incorrect because 别 is used exclusively for commands or prohibitions directed at someone else (e.g., "Don't do that!"). Zhang Wei is describing his own situation, not issuing a command.
D places 别 in the second blank, which has the same problem — 别 signals imperative mood, not a personal statement of intention.
A helpful memory rule: 没 = negates possession/existence (没有), 不 = negates habitual/intentional actions, 别 = negates commands. Keeping these three functions distinct will help you eliminate distractors quickly.
Question 6
A teacher says to her class: '同学们,请大家 迟到!明天有考试。' (Students, please everyone be late! There is an exam tomorrow.)
The teacher is issuing a warning to the whole class not to be late tomorrow. Which negation word best completes her sentence and why?
- 不 (bù) — because 不 negates future actions and is appropriate for warnings about tomorrow
- 没 (méi) — because 没 negates actions that have not yet occurred, fitting the future context
- 不是 (bù shì) — because 不是 clarifies that being late is not an acceptable state
- 别 (bié) — because 别 is used for negative commands or instructions directed at others (correct answer)
Explanation: When a sentence contains a command or instruction directed at someone else — especially a negative one like "don't do this" — you need a negation word that functions as an imperative, not just a declarative negation. That's the key distinction this question is testing.
In Chinese, 别 (bié) is the dedicated word for negative commands. It means "don't" in the sense of telling someone not to do something. Here, the teacher is directly instructing her students: "Please everyone, don't be late!" This is a command addressed to others, which is exactly where 别 belongs. Answer D is correct.
Now let's look at why the other options fall short. A) 不 (bù) negates general facts, habitual actions, or future intentions from a first-person perspective — for example, "我不去" (I'm not going). It describes what is or will be the case, not what someone is being told to do. Using 不 here would sound like a statement rather than an instruction. B) 没 (méi) negates actions that have already occurred or negates possession — it's a past-tense negator, as in "他没来" (He didn't come). Using 没 for a future command makes no grammatical sense. C) 不是 (bù shì) means "is not" and is used to negate identity or classification statements (e.g., "这不是书" — This is not a book). It cannot function as a command negator at all.
A useful memory trick: whenever you see a sentence telling someone not to do something — especially with words like 请 (please) — reach for 别. It's the "Don't!" of Mandarin commands.
Question 7
Read the following sentence: '他不去上班,因为他病了。' (He is not going to work because he is sick.)
In the sentence above, 不 is used to negate 去上班. A student argues that 没 should be used instead because 'not going' is the absence of an action. Which explanation best describes why 不 is actually correct here?
- 不 is correct because the sentence describes a habitual truth — he generally never goes to work — so habitual negation requires 不.
- 不 is correct because the cause given (being sick) makes the action impossible, and 不 is reserved for situations involving physical inability.
- 不 is correct because 没 can only negate the verb 有, so all other verbs must use 不 regardless of time or context.
- 不 is correct because the sentence expresses a current intention or decision not to go, negating a planned action, which requires 不 rather than 没. (correct answer)
Explanation: When negating verbs in Mandarin, the core question to ask yourself is: Why isn't the action happening — is it a matter of will/intention, or completion/occurrence? This distinction separates 不 from 没.
不 negates actions based on choice, intention, or decision — including planned actions that someone has decided against. 没 negates actions that did not occur or have not yet occurred in a factual, completed sense, often referencing past events. In this sentence, the subject has made a decision not to go to work because he is sick. The illness is the reason behind a deliberate choice, not simply a report that an event failed to happen. This is precisely where 不 belongs — it captures intentional or willful negation of a planned action. D is correct.
A is wrong because the sentence says nothing about habitual behavior. Saying "he's not going to work today" is situational, not a general truth about his habits. A misidentifies the sentence's aspect entirely.
B is wrong because 不 does not signal physical inability — that role belongs to 不能 or 没法. The fact that sickness is involved doesn't mean 不 indicates inability; it still reflects a decision.
C is wrong and represents a very common misconception. 没 can negate verbs other than 有 — it negates past or uncompleted actions broadly. Saying 没 only works with 有 is simply false.
Study tip: When you see negation in Mandarin, ask: intention or occurrence? 不 = won't/deciding not to; 没 = didn't/hasn't happened. This one rule resolves most 不 vs. 没 questions.
Question 8
A student wants to say 'I don't like spicy food' in Mandarin, expressing a general preference (not a past event). Which sentence is correct?
- 我没喜欢辣的食物。(Wǒ méi xǐhuān là de shíwù.)
- 我别喜欢辣的食物。(Wǒ bié xǐhuān là de shíwù.)
- 我不喜欢辣的食物。(Wǒ bù xǐhuān là de shíwù.) (correct answer)
- 我没有喜欢辣的食物。(Wǒ méiyǒu xǐhuān là de shíwù.)
Explanation: When negating verbs in Mandarin, the choice of negation word completely changes your meaning — so this question is really testing whether you know which negative particle belongs with stative/mental verbs expressing general preferences.
In Mandarin, 不 (bù) is the standard negation word for present or habitual states, opinions, and preferences. Since "liking" is a mental state rather than a completed action, 不 is exactly what you need here. 我不喜欢辣的食物 (Wǒ bù xǐhuān là de shíwù) correctly means "I don't like spicy food" as a general truth — making C the right answer.
Now let's look at why the other options fail. A uses 没 (méi), which negates completed past actions or changes in state (similar to saying something "didn't happen"). Using 没 with 喜欢 implies you're talking about a specific past event, not a general preference — it sounds unnatural and grammatically off for this context. B uses 别 (bié), which is a word for giving commands or telling someone not to do something (like "Don't eat that!"). Using 别 in a first-person statement about your own preferences makes no sense — you can't command yourself in this way. D uses 没有 (méiyǒu) followed by the verb 喜欢, which again points to past negation and sounds like "I haven't liked spicy food," implying a completed experience rather than a standing preference.
A quick memory tip: 不 = general/habitual negation, 没/没有 = past/completed negation, 别 = commands. When expressing preferences or personality traits, 不 is almost always your go-to.
Question 9
Which of the following sentences correctly uses negation to say 'She has not yet eaten lunch' (implying the action has not been completed)?
- 她不吃午饭了。(Tā bù chī wǔfàn le.) — She stopped eating lunch.
- 她别吃午饭。(Tā bié chī wǔfàn.) — She is told not to eat lunch.
- 她没吃午饭。(Tā méi chī wǔfàn.) — She has not eaten lunch. (correct answer)
- 她不是吃午饭。(Tā bù shì chī wǔfàn.) — What she is doing is not eating lunch.
Explanation: When expressing negation in Mandarin, the word you choose completely changes the meaning of the sentence — so it's critical to match the negator to the situation. For actions that have not yet been completed (like something that "hasn't happened yet"), Mandarin uses 没 (méi), not 不 (bù).
没 (méi) negates completed or experienced actions, making it the right tool for "she has not eaten lunch." In option C, 她没吃午饭 (Tā méi chī wǔfàn) correctly signals that the action of eating lunch has not occurred — exactly what the question asks for.
Now let's look at why the other choices miss the mark. Option A, 她不吃午饭了 (Tā bù chī wǔfàn le), uses 不 with 了, which signals a change of state — meaning she used to eat lunch but has now stopped. That's a very different meaning. Option B, 她别吃午饭 (Tā bié chī wǔfàn), uses 别, which is an imperative negator used to tell someone not to do something — it's a command, not a statement about what has or hasn't happened. Option D, 她不是吃午饭 (Tā bù shì chī wǔfàn), uses 不是 to contradict an identity or categorization, essentially saying "what she's doing is not eating lunch" — a completely different construction.
A helpful memory tip: think of 没 as your go-to for "hasn't done it yet" (past/completed actions), and 不 for habitual refusals or future intentions. Keeping these two negators clearly separated will save you from the most common traps on this topic.
Question 10
Which sentence correctly expresses 'My younger sister does not have a car' in Mandarin?
- 我妹妹不有汽车。(Wǒ mèimei bù yǒu qìchē.) — using 不 before 有
- 我妹妹没有汽车。(Wǒ mèimei méiyǒu qìchē.) — using 没有 to negate possession (correct answer)
- 我妹妹别有汽车。(Wǒ mèimei bié yǒu qìchē.) — using 别 to state she lacks a car
- 我妹妹不是有汽车。(Wǒ mèimei bù shì yǒu qìchē.) — using 不是 to deny possession
Explanation: When expressing negation in Mandarin, the specific negation word you choose depends entirely on what you're negating. Possession — having or not having something — follows a special rule that differs from general negation.
In Mandarin, the verb 有 (yǒu, "to have") is uniquely negated using 没 (méi) rather than the standard negator 不 (bù). This gives you 没有 (méiyǒu), meaning "do not have." So the correct sentence is B: 我妹妹没有汽车 (Wǒ mèimei méiyǒu qìchē) — "My younger sister does not have a car." The structure is straightforward: subject + 没有 + object.
Here's why the other options fail. A uses 不有 (bù yǒu), which is grammatically incorrect in Mandarin — 不 simply cannot be used to negate 有 when expressing possession. This is one of the most important fixed rules in basic Mandarin grammar. C uses 别 (bié), which means "don't" as a command or prohibition (like "don't do that!"). It expresses an instruction, not a statement of fact about possession — so it's both grammatically awkward and contextually wrong here. D uses 不是有 (bù shì yǒu), which mixes two constructions incorrectly. 不是 negates identity or classification (e.g., "is not a teacher"), not possession with 有.
A reliable study tip: whenever you see 有 in a possession context, mentally flag it as requiring 没有 for negation — never 不有. Think of it as a pair: 有 and 没有 always travel together, while 不 stays away from possession statements.
