📚 Year 9 WJEC English: Formulae and Theorems Quick Reference Handbook | Year 9 WJEC 英语：公式定理速查手册
Think of English as a precise system of patterns, rules and creative invention. Instead of memorising disconnected rules, you can treat each skill as a reliable formula or theorem. This quick-reference handbook rearranges key Year 9 WJEC English concepts into logical ‘equations’ and ‘proofs’ so you can diagnose every sentence, paragraph and piece of analysis with confidence.
把英语想象成一套精确的模式、规则与创造性发明的系统。你不必死记硬背零散的条文，而可以把每一项技能看作可依赖的公式或定理。这本速查手册将 WJEC Year 9 英语的核心概念重新编排为符合逻辑的“方程”与“证明”，帮助你自信地诊断每一个句子、段落和分析片段。
1. The Basic Sentence Construction Formula | 基本句子构造公式
The most fundamental formula in English is: Subject + Verb + (Object/Complement) = A Complete Thought. Every independent clause you write must contain, at minimum, a subject and a verb. If either element is missing, you have written a fragment, not a sentence. For example, ‘The library closes at five.’ satisfies the formula, while ‘Walking through the empty hall’ does not. Use this formula as a self-check before handing in any piece of writing.
英语中最基本的公式是：主语 + 动词 +（宾语/补语）= 一个完整的思想。你写的每一个独立分句至少必须包含一个主语和一个动词。如果缺少其中任何一个成分，你写的就不是句子，而是碎片。例如，“The library closes at five.”（图书馆五点关门）满足公式，而“Walking through the empty hall”（穿过空荡的大厅）则不满足。请在提交任何写作前用这一公式进行自我检查。
To build more sophisticated academic sentences, you can expand the formula by adding subordinate clauses or compound structures. A compound sentence, for instance, follows: Independent Clause + Comma + Coordinating Conjunction + Independent Clause. A complex sentence adds a dependent clause: Dependent Clause + Comma + Independent Clause, or the reverse. Mastering this expansion allows you to control rhythm and emphasis in analytical essays.
要构建更成熟的学术句子，你可以通过添加从句或并列结构来扩展公式。例如，并列句遵循：独立分句 + 逗号 + 并列连词 + 独立分句。复合句则增加从属从句：从属从句 + 逗号 + 独立分句，或者顺序相反。掌握这一扩展能让你在分析性论文中控制节奏与强调。
2. The Subject-Verb Agreement Theorem | 主谓一致定理
Apply this conditional theorem in the present tense: If the subject is third-person singular (he, she, it, or any singular noun), the base verb takes -s or -es. Otherwise, use the base form of the verb. This yields pairs such as ‘The artist paints’ versus ‘The artists paint’. The verb ‘to be’ follows an extended paradigm: I am, you/we/they are, he/she/it is. Treat indefinite pronouns like ‘everyone’ and ‘nobody’ as singular: ‘Everyone has a voice.’
在现在时中应用以下条件定理：如果主语是第三人称单数（he, she, it 或任何单数名词），动词原形需加 -s 或 -es。否则，使用动词原形。这就产生了“The artist paints”与“The artists paint”这样的对比。动词“to be”遵循一套扩展变化：I am, you/we/they are, he/she/it is。把“everyone”“nobody”等不定代词视为单数：“Everyone has a voice.”（每个人都有发言权）。
Pay special attention to intervening phrases that can mislead you. In a sentence like ‘The stack of papers is on the desk,’ the real subject is ‘stack,’ not ‘papers.’ Always locate the true head noun before deciding on the verb form. This theorem prevents one of the most frequent errors in Year 9 extended writing.
特别注意可能误导你的插入语。在“The stack of papers is on the desk”（那摞文件在书桌上）这类句子中，真正的主语是“stack”而不是“papers”。在决定动词形式之前，一定要先找到真正的中心名词。这条定理可以避免 Year 9 长篇写作中最常见的错误之一。
3. The Comma Usage Corollary | 逗号使用推论
Commas do not simply mark ‘a pause’; they function as logical separators in a sentence. Use them to separate items in a list: ‘We gathered leaves, twigs, and moss.’ Apply them before a coordinating conjunction when joining two independent clauses: ‘The storm intensified, and the crew prepared for the worst.’ Place a comma after an introductory word, phrase or clause: ‘After the play, the audience applauded.’
逗号并不仅仅标记“一处停顿”；它们在句子中起着逻辑分隔符的作用。用逗号分隔列举的项目：“We gathered leaves, twigs, and moss.”（我们收集了叶子、树枝和苔藓）。在连接两个独立分句的并列连词之前使用逗号：“The storm intensified, and the crew prepared for the worst.”（暴风雨加剧，船员们做好了最坏的准备）。在引导性的单词、短语或从句之后加逗号：“After the play, the audience applauded.”（戏剧结束后，观众鼓起掌来）。
Use commas to set off non-restrictive (extra) information: ‘My cousin, who lives in Cardiff, writes poetry.’ Do not use a comma when the information is essential to identify the noun. Additionally, commas separate direct address (‘Megan, could you explain this?’) and quotations from the rest of the sentence. Internalising this corollary will instantly improve the clarity of your writing.
用逗号隔开非限制性（附加的）信息：“My cousin, who lives in Cardiff, writes poetry.”（我住在卡迪夫的表妹写诗）。当信息对识别名词必不可少时，不要使用逗号。此外，逗号还用于分隔直接称呼（“Megan, could you explain this?”）以及把引文与句子其余部分隔开。内化这条推论能立刻提升你写作的清晰度。
4. The Apostrophe Possession and Contraction Lemma | 撇号所有格与缩写引理
For ownership, apply this lemma: Singular possessor → add ‘s; plural possessor ending in s → add only an apostrophe. Examples: the athlete’s medal (one athlete), the athletes’ medals (several athletes). Irregular plurals such as ‘children’ take ‘s: children’s stories. Never use an apostrophe with possessive pronouns: hers, ours, its, theirs.
对于所属关系，套用这条引理：单数拥有者 → 加 ‘s；以 s 结尾的复数拥有者 → 只加撇号。例如：the athlete’s medal（一名运动员的奖牌），the athletes’ medals（多名运动员的奖牌）。诸如“children”之类的不规则复数加 ‘s：children’s stories。绝对不要在物主代词上加撇号：hers, ours, its, theirs。
For contractions, the apostrophe shows where letters have been removed: do not → don’t, it is → it’s, will not → won’t. A common trap is confusing ‘it’s’ (it is) with ‘its’ (belonging to it). Apply the substitution test: if you can replace the word with ‘it is’ or ‘it has’, then an apostrophe is required. This lemma is a non-negotiable in WJEC spelling, punctuation and grammar assessments.
对于缩写形式，撇号标示字母被省略的位置：do not → don’t，it is → it’s，will not → won’t。一个常见的陷阱是混淆“it’s”（it is）与“its”（它的）。请使用替换测试：如果能用“it is”或“it has”来替换，就需要加撇号。在 WJEC 拼写、标点和语法评估中，这条引理是不可动摇的。
5. The P.E.E. Paragraph Proof | P.E.E. 段落证明
The backbone of analytical writing in WJEC English is the P.E.E. structure: Point + Evidence + Explanation = Persuasive Analysis. Your Point is a clear, arguable statement about the text. The Evidence is a short quotation or reference. The Explanation unpacks how the evidence proves the point, often by zooming in on language choices and their effect. Without all three elements, the analysis collapses.
WJEC 英语分析性写作的支柱是 P.E.E. 结构：论点 + 证据 + 解释 = 有说服力的分析。你的论点（Point）是关于文本的一个清晰可辩的陈述。证据（Evidence）是一个简短的引文或提及。解释（Explanation）则剖析证据如何证明论点，通常通过仔细审视语言选择及其效果。三者缺一，分析便站不住脚。
A robust Explanation follows a micro-formula: state what the writer does, quote a technique, and discuss the impact on the reader. For example, ‘The writer uses the metaphor “a storm of grief” to suggest overwhelming sorrow, making the reader feel the character’s uncontrollable pain.’ This prevents description (‘This is a metaphor’) and pushes you towards genuine analysis. Practise writing and labelling P.E.E. paragraphs until the rhythm becomes automatic.
一个扎实的解释遵循一套微观公式：陈述作者的写法，引用一种手法，并讨论对读者的影响。例如，“作者使用了‘a storm of grief’这一隐喻来暗示难以承受的悲痛，使读者感受到角色无法控制的痛苦。”这避免了纯粹的描述（“这是一个隐喻”），并推动你进行真正的分析。练习写作并标注 P.E.E. 段落，直到其节奏成为本能。
6. The Homophone Distinction Principle | 同音词区分原则
Homophones cause errors because spell-checkers cannot catch them. Use this principle: test meaning by substitution. Their = belonging to them; There = location or existence; They’re = they are. If the sentence still makes sense after replacing the word with ‘they are’, then ‘they’re’ is correct. Apply the same logic to your/you’re, its/it’s, and to/too/two.
同音词之所以会引发错误，是因为拼写检查程序无法发现它们。请运用如下原则：通过替换来测试含义。Their = 属于他们的；There = 位置或存在；They’re = they are。如果替换成“they are”后句子依然通顺，那么就该用“they’re”。用同样的逻辑来区分 your/you’re、its/it’s 以及 to/too/two。
For example, ‘Your dinner is ready’ (ownership) versus ‘You’re going to love this’ (you are). ‘I want to visit the park, too’ (also) versus ‘We walked to the park’ (direction). Turn each homophone set into a miniature theorem with a substitution test, and you will eliminate many careless mistakes from your writing folder.
例如，“Your dinner is ready”（你的晚饭好了，表所属）对比“You’re going to love this”（你会喜欢这个的，you are）。“I want to visit the park, too”（我也想去那个公园，也）对比“We walked to the park”（我们走向那个公园，方向）。把每一组同音词变成带替换测试的微型定理，你就能从作业夹中清除大量粗心大意的错误。
7. The Figurative Language Identification Theorem | 修辞语言识别定理
When analysing poetry or prose, identify figurative devices with a decision tree. If a comparison uses ‘like’ or ‘as’ → simile. ‘The moon hung like a lantern.’ If it directly states something is something else → metaphor. ‘The moon was a lantern.’ If human qualities are given to non-human objects → personification. ‘The moon watched over the town.’ This theorem anchors your close reading.
在分析诗歌或散文时，可以用决策树来识别修辞手法。如果比较使用了“like”或“as” → 明喻。“The moon hung like a lantern.”（月亮像灯笼一样挂着）。如果直接宣称某物就是另一物 → 暗喻。“The moon was a lantern.”（月亮是一盏灯笼）。如果把人类特质赋予非人的物体 → 拟人。“The moon watched over the town.”（月亮守望着小镇）。这一定理为你的精读提供了锚点。
Additional corollaries: If an inanimate object is addressed as if alive → apostrophe (e.g. ‘O wild West Wind!’). If there is extreme exaggeration → hyperbole. If words imitate sounds → onomatopoeia. If initial consonant sounds are repeated → alliteration. In WJEC unseen-text questions, rapidly labelling devices with this theorem earns marks for technical accuracy and gives you a bank of evidence for analysis.
补充推论：若一个无生命的物体被当作活物来呼告 → 呼语（例如“O wild West Wind!”）。若有极端的夸张 → 夸张。若词语模仿声响 → 拟声。若句首辅音重复 → 头韵。在 WJEC 非见面文本考题中，运用这一定理快速标注手法，能为你赢得技法准确性方面的分数，并为你提供分析用的证据库。
8. The Tense Consistency Law | 时态一致性定律
Choose a governing tense for your narrative or analytical paragraph and stick to it unless there is a clear, logical reason to shift. If you start in the past tense, keep all main actions in the past. A jarring shift like ‘She entered the room and sits down’ breaks the tense law. The correct version is ‘She entered the room and sat down.’ This law applies equally to fiction and non-fiction writing.
为你的叙述段落或分析段落选择一个主导时态，并坚持使用，除非有清晰合理的理由需要转换。如果你以过去时开始，就让所有主要动作都保持在过去时。像“She entered the room and sits down”这样突兀的转换就违反了时态定律。正确的版本是“She entered the room and sat down.”（她走进房间坐了下来）。这一定律同样适用于虚构与非虚构写作。
When writing about literature, use the literary present tense for discussing what a writer does: ‘Shakespeare portrays Macbeth as ambitious’, not ‘portrayed’. The words on the page continue to act upon every reader. Reserve the past tense for historical context outside the fiction. Applying this law consistently makes your critical voice sound authoritative and controlled.
当撰写关于文学的文章时，使用文学现在时来讨论作者做了什么：“Shakespeare portrays Macbeth as ambitious”（莎士比亚将麦克白描绘为野心勃勃），而不是“portrayed”。纸面上的文字会持续对每一位读者产生作用。把过去时留给虚构作品之外的历史背景。始终如一地运用这一定律，能让你的评析声音听上去权威而克制。
9. The Reading Comprehension Inference Formula | 阅读理解推理公式
WJEC comprehension questions frequently ask you to deduce ideas that are not directly stated. The formula is: Inference = Textual Clues + Background Knowledge. Read the question carefully, highlight telling details in the passage (a character’s sigh, a description of grey skies, a broken object), and combine them with what you already know about human behaviour and symbolism to form a logical conclusion.
WJEC 阅读理解题目经常要求你推断出未直接陈述的信息。公式是：推理 = 文本线索 + 背景知识。仔细审题，在篇章中高亮揭示性的细节（一个人物的叹息、对灰色天空的描写、一件破损的物品），并将它们与你已知的人类行为和象征意义相结合，从而得出一个合乎逻辑的结论。
Always phrase your inference using tentative language that points back to the text: ‘This implies that…’, ‘It is suggested that…’, ‘The writer hints at…’ because… (cite the clue). Avoid inventing details that have no trace in the passage. This formula turns inference from guesswork into a disciplined, evidence-based process that impresses examiners.
务必用指向原文的推测性语言来表述你的推理：“这暗示……”“文中表明……”“作者暗示了……”，因为……（引用线索）。避免编造在篇章中毫无痕迹的细节。这条公式把推理从猜测转变为一种循证的、有章法的过程，能令考官印象深刻。
10. The Creative Writing Story Arc Blueprint | 创意写作故事弧蓝图
A compelling story follows a time-tested progression: Exposition → Rising Action → Climax → Falling Action → Resolution. Exposition establishes setting and character. Rising Action builds tension through conflict and obstacles. The Climax is the turning point of maximum intensity. Falling Action shows the consequences, and Resolution ties up loose ends. Treat this as your narrative architecture formula.
一个引人入胜的故事遵循一条久经考验的推进路线：呈示 → 发展 → 高潮 → 下降 → 结局。呈示部分建立背景与人物。发展部分通过冲突和
