三次 (sān cì) = "three times". Example: 我去过北京三次 (wǒ qù guò běijīng sān cì) = "I've been to Beijing three times". Note: 次 never takes a verb between the number and itself.
Grammar
Use 次 (cì) as a measure word for repetitions
Ensure items being compared are of the same category
When using 比, compare equivalent items. 我的中文比你的更好 (wǒ de zhōngwén bǐ nǐ de gèng hǎo) = "My Chinese is better than yours" (ability vs ability).
Combine 把 with 了 for completed actions with clear results
Structure: 把 + object + verb + 了 + location/result. Example: 我把钥匙放在桌子上了 (wǒ bǎ yàoshi fàng zài zhuōzi shang le) = "I've put the key on the table".
Position of 了 with direct objects: verb + 了 + object
When there is a definite object, 了 comes after the verb but before the object. 我吃了一碗米饭 (wǒ chīle yì wǎn mǐfàn) = "I ate a bowl of rice". Compare: 我吃了 (I've eaten) vs 我吃了饭 (I've eaten [the meal]).
Position of 了 with direct objects: verb + 了 + object
When there is a definite object, 了 comes after the verb but before the object. 我吃了一碗米饭 (wǒ chīle yī wǎn mǐfàn) = "I ate a bowl of rice". Compare: 我吃了 (I ate/finished eating) vs 我吃了饭 (I ate [the meal]).
Add intensity modifiers after adjectives in 比 sentences
Add 很, 多了, or 得多 to strengthen the comparison. 他比我高很多 (tā bǐ wǒ gāo hěn duō) = "He is much taller than me"; 你的比我的便宜得多 (nǐ de bǐ wǒ de piányì de duō) = "Yours is much cheaper than mine".
Use 比 (bǐ) for comparisons: A 比 B + adjective
Structure: A 比 B + adjective. Example: 这个苹果比那个大 (zhège píngguǒ bǐ nàge dà) = "This apple is bigger than that one". The adjective or verb always follows 比.
Word order: subject → adverbial → verb → complement
Adverbials (like 很, 经常, 已经) come before the verb. 我很喜欢茶 (wǒ hěn xǐhuān chá) = "I like tea very much"; 他经常来 (tā jīngcháng lái) = "He comes often".
Different measure words for different noun categories
- 个 ge (general)
- 只 zhī (animals, items)
- 本 běn (books)
- 张 zhāng (paper, tickets, tables)
Examples: 一本书 (yī běn shū) vs 三张纸 (sān zhāng zhǐ).
Measure words always go between numbers and nouns
Order: numeral + measure word + noun. 三个苹果 (sān ge píngguǒ) = "three apples"; 两只猫 (liǎng zhī māo) = "two cats". Never skip the measure word.
了 (le) marks completed action or changed situations
Add 了 after a verb when the action is finished or a situation has changed. Examples: 我吃了饭 (wǒ chīle fàn) = "I ate"; 天黑了 (tiānhēi le) = "It got dark".
Use 把 (bǎ) to show direct action on an object
Use 把 when emphasizing that the subject directly affects or changes the object. Example: 我把书放在桌子上 (wǒ bǎ shū fàng zài zhuōzi shang) = "I put the book on the table" (emphasizing the completed placement).
Motion verbs 来/去 rarely work with 把 (bǎ)
来 (come) and 去 (go) rarely take 把: ✗ 把他来 → ✓ 他来了. 把 is for actions that change the object's state or position.
Measure word 个 (ge) is the default for most nouns
When unsure, 个 works for many nouns: 一个人 (person), 五个问题 (questions), 两个地方 (places). But use 本 for books, 只 for animals, 张 for paper/tables.
Extended 比 comparison: A 比 B adjective + quantity/degree
我比你多两个苹果 (I have two more apples than you). 比 comparisons can include specific quantities or degrees beyond just the adjective.
把 (bǎ) requires a complement or specified outcome
把书放在桌子上 ✓ (put the book on the table, has a locative complement). 我把书 ✗ (incomplete). 把 needs the verb to carry specific information about the action's direction or result.
Ba (把) requires a complement or specified outcome
把书放在桌子上 ✓ (put the book on the table, has a locative complement). 我把书 ✗ (incomplete). 把 needs the verb to include specific information about the action's direction or result.
Sentence-final 了 marks a change of state
天气变热了 (the weather has turned hot), the final 了 emphasizes a change of state. Compare 吃了饭 (verb-了, action completed) with 吃饭了 (sentence-final 了), which signals a new situation such as "it's time to eat".
Bi (比) for comparison: A 比 B adjective
我比你高 (I am taller than you), the comparative object (你) goes between 比 and the adjective (高). Always: A + 比 + B + adjective.
Word order: number + measure word + adjective + noun
三个红苹果 (three red apples), never *红三个苹果. The number and measure word always come first; the adjective sits between the measure word and the noun.
State verbs don't work with ba (把)
State verbs like 喜欢 (like), 爱 (love), 怕 (fear), 了解 (understand) cannot take 把: ✗ 把你喜欢 → ✓ 喜欢你. Use 把 only with action verbs that directly affect an object.
Measure words must go between numbers and nouns
Never say 一人 or 三书, you need a classifier: 一个人 (one person), 三本书 (three books). Each noun has its paired measure word: 一只猫 (one cat), 一张纸 (one sheet of paper).
了 (le) marks completion or change of state, not just past tense
了 expresses completion or a change of state, not necessarily "happened in the past". 我看了一本书 (Wǒ kànle yì běn shū) = "I read a book". 了 can refer to today, tonight, or last week, context decides.
Ba (把) emphasizes direct impact on the object
把 places the object before the verb, highlighting action or result. Compare: 我吃了饭 (ate rice) vs 我把饭吃了 (finished eating the rice), the latter stresses completion or full consumption.
没 negates past actions; 不 negates habits or traits
没 denies what already happened: 我没吃饭 (I didn't eat). 不 denies habits or qualities: 我不喜欢吃米饭 (I don't like eating rice). 没 for past, 不 for present/future.
个 is the most common measure word for people and things
个 works with most nouns, especially people and general objects. 一个人 (one person), 两个苹果 (two apples), 三个主意 (three ideas). When unsure, 个 is usually safe.
在 marks location or time of action
在 specifies where or when an action occurs. 我在办公室工作 (I work at the office), 我在三点开会 (I have a meeting at 3 o'clock). 在 is essential when indicating place or time.
了 after verb (completion) vs 了 at sentence end (change)
了 after the verb means the action finished; 了 at the sentence end signals a change of state. 我喝了水 (I drank the water [done]) vs 天气冷了 (The weather has become cold). Position matters.
Locative phrases come before the verb, after subject
Place words must precede the verb. 我在家里吃饭 (I eat at home), not 我吃饭在家里. Location is never placed after the verb.
Directional complements follow the verb to show motion
A directional word after the verb shows where the action goes: 拿进来 (bring in), 走出去 (walk out), 跑上楼 (run upstairs). Pattern: verb + direction.
