Classification of Simple Sentences by Mood: Declarative, Interrogative, Imperative, and Exclamatory Sentences
When writing or tackling reading comprehension, you will often encounter a wide variety of sentences. In Chinese grammar, sentences can be categorised by their internal syntactic structure into "subject-predicate sentences" and "non-subject-predicate sentences" (see the relevant chapters for details). However, when classified by communicative purpose and mood (語氣), simple sentences fall into four fundamental types: declarative sentences, interrogative sentences, imperative sentences, and exclamatory sentences.
Don't worry if memorising sentence types feels overwhelming at first! As long as you master the core characteristics, modal particles, and punctuation rules of each sentence type, you will not only be able to accurately interpret the author's thoughts and emotions in Paper 1 Reading Comprehension, but also flexibly vary your sentence structures in Paper 2 Writing. This will demonstrate superb control of language and satisfy the syllabus requirements for AO4 (grammatical and punctuation accuracy).
I. Declarative Sentences (陳述句)
1. What is a Declarative Sentence?
A declarative sentence is used to narrate an event, explain a fact, describe a situation, or express the speaker's viewpoint and attitude. Declarative sentences are the most common and frequently used sentence type in daily writing and dialogue.
2. Intonation and Punctuation
The intonation of a declarative sentence is generally flat and even, with a relatively long pause at the end. In written Chinese, it always ends with a full stop (句號 "。").
3. Categories and Indicators of Declarative Sentences
Declarative sentences mainly come in two forms:
(1) Affirmative Declarative Sentences: Make an affirmative statement about a thing, situation, or principle.
Example: 人工智能正在深刻改變現代學生的學習模式。(Artificial intelligence is profoundly changing the way modern students learn. — Explaining a fact)
Example: 傳統節日承載著豐富的文化內涵。(Traditional festivals carry rich cultural connotations. — Expressing a viewpoint)
(2) Negative Declarative Sentences: Negate an action, condition, or situation using negative words (否定詞). Common negative words include "不" (not), "沒有" (did not / do not have), "別" (do not), "非" (is not), and "未" (have not yet).
Example: 這項科技創新並非一朝一夕就能完成的。(This technological innovation is by no means something that can be completed overnight.)
Example: 面對氣候變化的挑戰，我們不能坐視不理。(Facing the challenge of climate change, we cannot simply sit by and do nothing.)
4. Common Modal Particles
Declarative sentences sometimes add modal particles (語氣助詞) at the end to soften the tone or add a specific nuance, such as "的", "了", "呢", "罷了", and "而已".
Example: 他只是去圖書館借幾本書而已。(He is merely going to the library to borrow a few books, that's all.)
[Key Takeaway] The core purpose of a declarative sentence is to "state a fact or viewpoint". The tone is neutral and even, and it must end with a full stop "。".
II. Interrogative Sentences (疑問句)
1. What is an Interrogative Sentence?
An interrogative sentence is used by the speaker to ask a question, express doubt, and elicit a response from the listener. In specific contexts, it can also be used to heighten rhetorical impact (such as in rhetorical questions). In written Chinese, it always ends with a question mark (問號 "？").
2. The Four Basic Forms of Interrogative Sentences
Mastering these four structural types will help you accurately identify how a question is framed during text analysis:
(1) Yes/No Questions (是非問):
These propose a statement and ask whether it is "yes" or "no". The typical structure is a declarative statement followed by an interrogative modal particle such as "嗎" or "吧". The answer simply requires confirmation or denial.
Example: 你明天會參加學校的環保義工活動嗎？(Will you take part in the school's environmental volunteering activity tomorrow?)
Example: 這篇關於社交媒體影響的報告是你寫的吧？(This report on the impact of social media was written by you, right?)
(2) Wh- Questions / Specific Inquiries (特指問):
The speaker asks for specific, unknown information. The sentence must contain an interrogative pronoun (疑問代詞) (such as "誰" [who], "甚麼" [what], "哪裏" [where], "為甚麼" [why], "怎樣" [how], "多少" [how much/many], etc.). The response cannot be a simple "yes" or "no"; specific details must be provided.
Example: 我們應當如何平衡課業學習與課外活動？(How should we balance academic studies with extracurricular activities?)
Example: 是誰在音樂節的開幕式上發表演說？(Who is delivering the speech at the music festival's opening ceremony?)
(3) Alternative Questions (選擇問):
These present two or more coordinate options, asking the listener to choose one. Common correlative conjunctions are "是……還是……" (is it... or...) or simply "還是" (or).
Example: 你打算在大學主修電腦科學，還是選擇商科課程？(Do you plan to major in computer science at university, or choose a business course?)
Example: 今天下午我們去球場踢足球，還是留在家中溫習？(Shall we play football at the pitch this afternoon, or stay home to revise?)
(4) A-not-A Questions / Affirmative-Negative Questions (正反問):
These juxtapose the affirmative and negative forms of the predicate, asking the listener to make a choice. The particle "嗎" is generally not used at the end.
Example: 你最近忙不忙？(Have you been busy or not lately?)
Example: 我們能不能在考試前把這個課題複習完畢？(Can we or can we not finish revising this topic before the exam?)
[Did You Know?]
In rhetorical devices, both "rhetorical questions" (反問) and "hypophora" (設問) fall under interrogative sentences in terms of grammatical structure and mood. Hypophora involves "asking without real doubt and answering oneself" to provoke thought; a rhetorical question involves "asking what is already known, with the answer implied in the question" to enhance persuasion.
[Common Pitfall]
Misconception: Adding a question mark the moment you see a question word.
If a sentence contains an interrogative pronoun (e.g. "誰", "甚麼") within a non-question context and the sentence merely states a fact (indirect question/nominal clause), you must never use a question mark.
Incorrect: 我不知道他今天為甚麼遲到？
Correct: 我不知道他今天為甚麼遲到。 (I don't know why he is late today. — The overall sentence is declarative; its main clause is "I don't know...")
III. Imperative Sentences (祈使句)
1. What is an Imperative Sentence?
An imperative sentence is used to demand, order, request, advise, forbid, or urge someone to do (or not do) something. Because imperative sentences deliver direct directives to the listener, the subject is typically the second person "你" (you) or "你們" (you all), and it is frequently omitted.
2. Two Main Tones and Punctuation Usage
Punctuation in imperative sentences depends on the intensity of the tone:
(1) Commands and Prohibitions (Strong, Stern Tone):
The sentence usually ends with an exclamation mark (嘆號 "！").
Common indicators include "必須" (must), "立正" (attention), "嚴禁" (strictly prohibited), "不要" (do not), "別" (don't), etc.
Example: 請勿在展覽廳內高聲喧嘩！(Do not make loud noises in the exhibition hall!)
Example: 立刻把作業交上來！(Hand in your homework immediately!)
(2) Requests, Advice, and Urging (Polite, Soft Tone):
The sentence usually ends with a full stop (句號 "。"), though an exclamation mark (嘆號 "！") is also possible when more emphasis is needed.
Polite terms or softening modal particles are often used, such as "請" (please), "希望" (hope), "吧", "啊", etc.
Example: 請大家翻開課本第三十五頁。(Please turn to page 35 in your textbooks.)
Example: 時間不早了，我們快點出發吧。(It's getting late; let's set off quickly.)
[Key Takeaway] The key to identifying an imperative sentence lies in its communicative intent: as long as it expresses an intention to "direct someone to act", whether the tone is forceful or gentle, it is an imperative sentence.
IV. Exclamatory Sentences (感嘆句)
1. What is an Exclamatory Sentence?
An exclamatory sentence is used to express strong emotions, including joy, anger, sorrow, admiration, surprise, fear, and more. The speaker injects intense emotion through intonation and exclamatory markers.
2. Intonation and Punctuation
The intonation of an exclamatory sentence typically starts high and falls towards the end, carrying rich emotion. In written Chinese, it always ends with an exclamation mark (嘆號 "！").
3. Common Structures of Exclamatory Sentences
Exclamatory sentences usually feature distinct lexical markers:
(1) Using Exclamatory Adverbs Paired with Modal Particles:
Common patterns include "多麼……啊！" (how...!), "真……啊！" (truly...!), "太……了！" (too/so...!), "好……呀！" (so...!), etc.
Example: 維多利亞港的夜景多麼迷人啊！(How captivating the night view of Victoria Harbour is!)
Example: 這部探討氣候變化的紀錄片拍得太震撼了！(This documentary exploring climate change was filmed so powerfully!)
(2) Using Interjections at the Beginning:
Interjections (嘆詞, such as "哎呀", "天哪", "哈哈", "唉") stand independently outside the core sentence structure and directly convey raw emotion.
Example: 哎呀，我不小心把試卷弄濕了！(Oh no, I accidentally got my exam paper wet!)
Example: 天哪！這種古老的手工藝竟然保存得如此完好！(Good heavens! This ancient craft has been preserved so remarkably well!)
[Common Pitfall]
Do not confuse an "imperative sentence" ending with an exclamation mark with an "exclamatory sentence":
快跑！ (Run quickly! — Imperative sentence: urging action)
這裏的空氣真清新啊！ (How fresh the air is here! — Exclamatory sentence: expressing admiration)

・Common end punctuation: Exclamation mark "！"
2. Flexible Sentence Variety in Writing (Boosting Paper 2 AO3 / AO4 Performance)
In Chinese First Language writing assessment, an essay composed solely of repetitive declarative sentences will read flat, lifeless, and rhythmically monotonous. Skillfully weaving in sentences with different moods will substantially enhance your writing's expressive power:
・Make effective use of hypophora and rhetorical questions (Interrogative Sentences): In argumentative or expository essays, opening a paragraph with hypophora hooks the reader's curiosity; using rhetorical questions during in-depth argumentation reinforces your stance and resonates with the reader.
・Integrate exclamatory sentences: At the climax or resolution of a narrative or descriptive essay, judiciously placed exclamatory sentences transmit your inner feelings directly to the reader, deepening the emotional resonance of your theme.
・Apply imperative sentences in letters and speeches: Paper 2 directed writing frequently involves letters, proposals, or speeches. When delivering a call to action to your audience, deploying impactful imperative sentences (e.g. "Let us join hands to protect our planet!") demonstrates persuasive leadership and authority.
[Exam Pitfall Warnings]
1. Overusing exclamation marks: Avoid filling your essay with excessive exclamatory sentences and exclamation marks; an over-emotional tone undermines the maturity and composure of your writing.
2. Confusing question marks with full stops: In sentences containing interrogative pronouns like "誰" (who), "甚麼" (what), or "哪裏" (where) that function as indirect questions or clauses without asking an actual question, take care not to mistakenly append a question mark.
3. Inappropriate register in imperative sentences: In formal correspondence (such as writing to elders or heads of organisations), prefer polite imperative sentences featuring "請" (please) or "懇請" (earnestly request) paired with a full stop. Avoid blunt, demanding exclamation marks to maintain an appropriately polite and respectful register.
