1. The '是…的' Structure for Emphasis | '是…的' 强调结构
The '是…的' construction is used to highlight the time, place, manner, or agent of a past action. Think of it as a frame that isolates the piece of information you want to stress. The basic formula is: Subject + 是 + [detail to emphasise] + Verb + 的. The '是' can sometimes be omitted in positive sentences, but keeping it makes the emphasis stronger.
'是…的' 结构用于强调一个已发生动作的时间、地点、方式或实施者。可以把它想象成一个框架，把你想突出的信息单独拎出来。基本公式是：主语 + 是 + [要强调的细节] + 动词 + 的。在肯定句里 '是' 有时可以省略，但保留它会使强调语气更强。
- Formula: S + 是 + [Time/Place/Manner/Agent] + V + 的
- Example: 我是昨天收到这封邀请信的。
English: It was yesterday that I received this invitation letter. - Example: 这本小说不是我在图书馆借的，是在网上买的。
English: It was not from the library that I borrowed this novel — I bought it online.
| Key detail | Sentence with 是…的 |
| Manner (by plane) | 他是坐飞机来伦敦的。 |
| Place (in the café) | 我们是在咖啡馆第一次见面的。 |
| Agent (by mum) | 这条围巾是妈妈给我织的。 |
2. The '把' Sentence Formula | '把'字句公式
The '把' construction shifts the focus to what happens to a particular object — it often implies disposal, change, or a result affecting that object. The formula: Subject + 把 + Object + Verb + Complement/Other element. Never leave the verb bare; a complement, result, duration, or at least 了 is required to make the sentence complete.
'把'字句将焦点转移到某一特定对象上发生的事——通常意味着对该对象的处置、改变或结果。公式：主语 + 把 + 宾语 + 动词 + 补语/其他成分。动词绝不能光秃秃地结尾；必须带上补语、结果、时量或者至少一个 '了'，句子才完整。
- Formula: S + 把 + O + V + Complement / 了
- Example: 请同学们把作业本放在讲台上。
English: Please put your exercise books on the podium, students. - Example: 他把那杯热茶全都喝完了。
English: He drank up all of that cup of hot tea. - Negative form: S + 没(有) / 别 + 把 + O + V + Complement
- Example: 你千万别把校服弄丢了。
English: Whatever you do, don't lose your school uniform.
3. The '比' Comparison Formula | '比'字比较句公式
Comparisons using '比' follow a strict word order that often confuses learners because it places the adjective right after the second item. The core formula is: A + 比 + B + Adjective. To intensify the comparison, add 还 or 更 before the adjective. For a precise difference, attach the complement of quantity after the adjective.
用 '比' 进行比较时，语序非常固定，常常令学习者困惑，因为形容词紧跟在第二个比较项之后。核心公式：A + 比 + B + 形容词。要增强比较语气，可在形容词前加 '还' 或 '更'。若想表达具体的差异，则在形容词后附加数量补语。
- Formula: A + 比 + B + (更/还) + Adj (+ 一点儿 / 得多 / Number phrase)
- Example: 今天的风比昨天大多了。
English: The wind today is much stronger than yesterday. - Example: 姐姐比我大半岁。
English: My elder sister is half a year older than me. - Formula for negation: A + 没有 + B + Adj or A + 不比 + B + Adj (less common, often used in refutation)
- Example: 这间教室没有那间明亮。
English: This classroom is not as bright as that one.
4. Complement of Degree with '得' | '得'字程度补语
When you want to describe how an action is performed or to what degree a state exists, the particle '得' introduces a complement of degree. The formula: Verb/Adjective + 得 + Descriptive phrase. This structure can also handle extreme degrees by using '得' followed by a clause or a set expression.
当你想描述一个动作进行得如何或某种状态达到了什么程度时，助词 '得' 引出程度补语。公式：动词/形容词 + 得 + 描述性短语。该结构还可以通过 '得' 后接一个从句或固定表达来处理极端的程度。
- Formula: V / Adj + 得 + Complement
- Example: 妹妹听到这个消息高兴得跳了起来。
English: My younger sister was so happy to hear the news that she jumped up. - Example: 他说中文说得非常流利。
English: He speaks Chinese very fluently. - If there is an object, the verb is often repeated: S + V + O + V + 得 + Complement. Alternatively, the object can be placed at the beginning.
- Example: 他踢足球踢得满头大汗。
English: He played football until he was drenched in sweat.
5. Cause and Effect with '因为…所以…' | 因果关系连词
This paired conjunction is the backbone of cause-and-effect reasoning in Chinese. The formula 因为 + Cause, 所以 + Result is used far more frequently together than its English counterparts 'because... so...'. While the 因为 clause can stand before or after the main clause in speech, formal writing prefers cause before result.
这对关联词是中文因果推理的骨架。公式 因为 + 原因，所以 + 结果 同时使用的频率远高于英语中的 because... so...。虽然口语中原因分句可前可后，但正式书面语倾向于原因在前、结果在后。
- Formula: 因为 + Reason, 所以 + Result
- Example: 因为学校附近的马路在施工，所以公交车改道了。
English: Because the road near the school is under construction, the bus has been diverted. - You can use 由于 instead of 因为 in more formal contexts, and 因此 in place of 所以.
- Example: 由于时间紧迫，因此我们只在公园停留了半个小时。
English: Owing to the tight schedule, we only stayed in the park for half an hour.
6. Concessive Clauses with '虽然…但是…' | 让步关系连词
This formula expresses a contrast between an accepted fact and an unexpected outcome. 虽然 + Concession, 但是/可是/却 + Contrast. Even though 虽然 introduces a factual situation, the second clause always presents a surprising or opposing result. Note that 却 is placed after the subject inside the second clause.
这个公式表达了一个已接受的事实与一个意料之外的结果之间的对比。虽然 + 让步，但是/可是/却 + 转折。尽管 '虽然' 引出一个事实情况，但第二分句总是呈现令人意外或对立的结果。注意 '却' 要放在第二分句主语的后面。
- Formula: 虽然 + Fact, 但是/可是/却 + Contrast
- Example: 虽然这道数学题看起来简单，但是全班只有三个人答对。
English: Although this maths problem looked simple, only three people in the whole class got it right. - Example: 爷爷虽然已经七十岁了，精力却像年轻人一样充沛。
English: Although my grandpa is already seventy, his energy is just as abundant as a young person's.
7. '除了…以外' for Inclusion and Exclusion | '除…以外' 包含与排除结构
The '除了…以外' pattern is a versatile logical operator meaning 'apart from' or 'besides'. There are two main formulas depending on whether you want to include or exclude. For addition: 除了 + A (以外), 还/也 + B. For restriction: 除了 + A (以外), 都 + V. The 以外 can be dropped in casual speech but is common in writing.
'除了…以外' 句式是一个多功能的逻辑运算符，表示“除了…之外”。根据你是想包含还是排除，主要有两个公式。表示追加：除了 + A (以外)，还/也 + B。表示限制：除了 + A (以外)，都 + 动词。口语中 '以外' 可以省略，但书面语中常见。
- Formula for including: 除了 + A (以外), S + 还/也 + V + B
- Example: 除了中文以外，我还会说法语和一点日语。
English: Apart from Chinese, I can also speak French and a little Japanese. - Formula for excluding: 除了 + A (以外), S + 都 + V / S + 全 + V
- Example: 除了小美以外，同学们都报了名参加比赛。
English: Except for Xiaomei, all the classmates signed up for the competition.
8. The '一…就…' Structure | '一…就…' 结构
This compact pattern links two events where the second follows the first immediately or as a direct consequence. The formula 一 + Action₁, 就 + Action₂ implies 'as soon as... then...'. It can also express a conditional link where the first action inevitably triggers the second. The subjects of the two clauses can be the same or different.
这个紧凑的结构连接两个事件，第二个紧接着第一个发生，或是第一个的直接结果。公式 一 + 动作₁，就 + 动作₂ 含有“刚一…就…”的意思。它也可以表示一种条件联系，即第一个动作必然触发第二个。两个分句的主语可以相同也可以不同。
- Formula: S₁ + 一 + V₁, (S₂) + 就 + V₂
- Example: 弟弟一进房间就把书包扔在了地上。
English: As soon as my younger brother entered the room, he threw his schoolbag on the floor. - Example: 天一冷，妈妈就给我们准备了厚棉被。
English: Once it turns cold, Mum gets thick quilts ready for us. - To describe a quick succession in the past, add 了 after the first verb: 一 + V了 + O, 就 + V₂
- Example: 他一转学了，我们就很少有机会一起踢球了。
English: Once he transferred schools, we hardly had chances to play football together.
9. Conditional '如果…就…' | 条件句 '如果…就…'
This is the standard formula for constructing 'if... then...' sentences. 如果 + Condition, (S) + 就 + Result. The 就 is essential in the main clause to signal the consequence, even if the English translation would not use 'then'. The condition clause can also be introduced by 要是 or 假如 in colloquial contexts.
这是构建“如果…那么…”句子的标准公式。如果 + 条件，(主语) + 就 + 结果。主句中的 '就' 至关重要，用来标示后果，即使英语译文中不一定出现 then。条件分句在口语中也可以由 '要是' 或 '假如' 引出。
- Formula: 如果 + Condition, S + 就 + Result
- Example: 如果明天下暴雨，运动会就推迟到周五。
English: If there is a heavy rainstorm tomorrow, the sports day will be postponed to Friday. - Example: 如果你对结果不满意，就可以向学生会提出申诉。
English: If you are not satisfied with the result, you can lodge an appeal with the student council. - For negative conditions: 如果不 / 要是不 + V, 就 + Negative/Alternative
- Example: 要是不想迟到，咱们就坐地铁吧。
English: If we don't want to be late, let's take the subway.
10. Location and Direction Formulas | 方位介词公式
Spatial relationships in Chinese rely on a set of position words that follow a noun to form a location phrase. The core formula is 在 + Place/Location phrase + Verb or 从 + Place + Direction + Verb. Key postpositions include 上 (on), 里 (in), 下 (under), 后 (behind), 前 (in front), 旁 (beside), 左/右 (left/right). When combining with a place name, the postposition may be omitted only if the place itself serves as a location (e.g., 在北京, not 在北京里).
中文的空间关系依赖一组方位词，它们跟在名词之后构成处所短语。核心公式是 在 + 处所短语 + 动词 或 从 + 地点 + 方位 + 动词。关键的方位词包括 上、里、下、后、前、旁、左、右。与地点名称连用时，只有当地点本身就充当处所时方位词才可以省略（比如可以说“在北京”，不说“在北京里”）。
- Formula: 在 + N + 上/里/下 + V; 从 + N + 上/里 + V
- Example: 粉笔在黑板边上，不在讲台上面。
English: The chalk is beside the blackboard, not on top of the podium. - Example: 我们从图书馆里借到了那本参考书。
English: We borrowed that reference book from inside the library. - Direction with 往 / 向: 往 + Direction + V
- Example: 出了地铁站往右拐，走五十米就到了。
English: Turn right after exiting the subway station, walk fifty metres and you'll be there.
11. Action Progression with '正在' and '着' | 动作进行态公式
To express an ongoing action, Chinese offers several parallel formulas: 正在 + Verb, 在 + Verb, and Verb + 着. While 正在 emphasises the 'right in the middle of' aspect, 着 often signals a continuous state or a background action. You can combine them: 正在 + V + 着 indicates a sustained ongoing action.
表达正在进行的动作，中文提供了几个平行的公式：正在 + 动词、在 + 动词、动词 + 着。'正在' 强调“正处于……的过程中”，而 '着' 通常表示持续的状态或背景动作。两者可以结合：'正在 + V + 着' 表示持续进行的动作。
- Formula: S + 正在 / 在 + V (+ O); S + V + 着 (+ O)
- Example: 现在校长正在和几位来访的家长谈话。
English: The headteacher is currently talking with several visiting parents. - Example: 桌上放着一本摊开的相册。
English: An open photo album is lying on the table. - Formula: S + 正在 + V + 着 + O
- Example: 窗外正在下着毛毛细雨。
English: A fine drizzle is falling outside the window.
12. The '越来越' and '越…越…' Patterns | '越来越' 和 '越…越…' 渐变公式
These patterns express a progressive change or a correlation between two changes. 越来越 + Adjective/Verb means 'more and more...'. 越 + V/Adj₁, 越 + V/Adj₂ means 'the more... the more...'. Both are extremely useful for describing trends in speaking and essay writing.
这两种结构表示逐渐的变化或两种变化之间的关联。越来越 + 形容词/动词 意为“越来越……”。越 + 动词/形容词₁，越 + 动词/形容词₂ 意为“越……越……”。在口语和作文里描述趋势时，这两者都非常有用。
- Formula: 越来越 + Adj / (psychological) V
- Example: 新开的购物中心越来越热闹了。
English: The newly opened shopping centre has become more and more bustling. - Formula: 越 + V₁, 越 + V₂/Adj₂
- Example: 这本小说我越看越想看，根本放不下来。
English: The more I read this novel, the more I want to continue — I simply cannot put it down. - Example: 有时候，知识越多，越觉得自己懂得少。
English: Sometimes, the more knowledge one has, the more one feels one knows so little.
