1. Sentence Structure Formulas | 句子结构公式
Every sentence is built on a formula. Understanding these patterns helps you write clearly and avoid fragments or run-ons.
每个句子都建立在公式之上。理解这些模式有助于你清晰地写作，避免残缺句或连写句。
Simple Sentence Formula: Subject + Verb (+ Object/Complement). This is one independent clause expressing a complete thought. Example: 'The sun (S) rose (V) over the hills (O).'
简单句公式：主语 + 动词（+ 宾语/补语）。这是一个表达完整思想的独立分句。例句：“太阳（主语）升起（动词）在山丘上（宾语）。”
Compound Sentence Formula: Independent Clause + , + Coordinating Conjunction + Independent Clause. Use FANBOYS (for, and, nor, but, or, yet, so). Example: 'I wanted to go, but it was raining.'
并列句公式：独立分句 + 逗号 + 并列连词 + 独立分句。使用 FANBOYS（for, and, nor, but, or, yet, so）。例句：“我想去，但正在下雨。”
Complex Sentence Formula: Independent Clause + Subordinating Conjunction + Dependent Clause (or reversed with a comma). Subordinators include because, although, when, since, if, while. Example: 'Although it was cold (dependent), we went swimming (independent).'
复杂句公式：独立分句 + 从属连词 + 从属分句（或颠倒顺序并用逗号）。从属连词包括 because, although, when, since, if, while。例句：“尽管天气冷（从属分句），我们还是去游泳了（独立分句）。”
Compound-Complex Formula: At least two independent clauses + one or more dependent clauses. Example: 'She finished her homework, but she forgot the essay that was due on Monday.'
并列复杂句公式：至少两个独立分句 + 一个或多个从属分句。例句：“她完成了家庭作业，但忘记了周一要交的论文。”
2. Punctuation Rules | 标点规则定理
Punctuation acts as the road signs of writing; it tells the reader when to pause, stop, or connect ideas. Master these formulas to make your writing crystal clear.
标点是写作中的路标；它告诉读者何时停顿、停止或连接观点。掌握以下公式可使你的写作清晰明了。
Full Stop Formula: Place a full stop (.) at the end of every complete statement. It marks the end of a sentence. Always start the next sentence with a capital letter.
句号公式：在每个完整的陈述句末尾使用句号（.）。它标志一个句子的结束。下一个句子的首字母始终大写。
Comma Formula: Use a comma (,) to separate items in a list, after introductory phrases, before coordinating conjunctions in compound sentences, and to set off non-essential information. Example: 'After the movie, we went for pizza, pasta, and salad.'
逗号公式：使用逗号（,）分隔列表项、用于引导性短语之后、并列句的并列连词之前，以及分隔非必要信息。例句：“电影结束后，我们去吃了比萨、意面和沙拉。”
Apostrophe Formula: Use an apostrophe (') to show possession (the girl's book) or to indicate missing letters in contractions (do not → don't). For plural possession, place after s: the girls' books.
撇号公式：用撇号（'）表示所属（女孩的书）或缩合形式中省略的字母（do not → don't）。复数所有格则将撇号放在 s 之后：女孩们的书。
Semicolon Formula: Use a semicolon (;) to link two closely related independent clauses without a conjunction, or to separate items in a complex list. Example: 'The sun was low; the shadows grew long.'
分号公式：用分号（;）连接两个紧密关联的独立分句而不使用连词，或分隔复杂列表中的项目。例句：“太阳很低；影子变长了。”
Colon Formula: Use a colon (:) to introduce a list, an explanation, or a quotation after a complete independent clause. Example: 'She had one goal: to win the race.'
冒号公式：用冒号（:）引入列表、解释或在独立分句后引入引语。例句：“她只有一个目标：赢得比赛。”
3. Parts of Speech Quick Reference | 词性速查
Every word in a sentence plays a role. Knowing the eight parts of speech is like knowing the formula that makes an engine run.
句子中的每个词都扮演一个角色。了解八大词性就像了解让引擎运转的公式。
Noun: A word that names a person, place, thing, or idea. Abstract nouns (e.g., love, freedom) name concepts; concrete nouns (e.g., table, cat) name physical objects. Proper nouns (capitalised) name specific entities.
名词：命名人、地方、事物或概念的词。抽象名词（如爱、自由）命名概念；具体名词（如表、猫）命名实物。专有名词（需大写）命名特定实体。
Verb: A word that shows action (run, think) or state of being (is, become). The main verb carries the core meaning; auxiliary verbs (helping verbs) form tenses and questions.
动词：表示动作（跑、想）或存在状态（是、变得）的词。主动词承载核心意义；助动词（帮助动词）构成时态和问句。
Adjective: A word that describes a noun or pronoun. It answers 'which?', 'what kind?', or 'how many?' Adjectives often come before the noun or after a linking verb (e.g., 'The sky is blue').
形容词：描述名词或代词的词。它回答“哪个？”“哪种？”“多少？”等问题。形容词常位于名词前或连系动词后（如“天空是蓝色的”）。
Adverb: A word that modifies a verb, an adjective, or another adverb. It often ends in -ly and answers 'how?', 'when?', 'where?', or 'to what extent?' Example: 'She sang beautifully.'
副词：修饰动词、形容词或其他副词的词。常以 -ly 结尾，回答“如何？”“何时？”“何处？”“到什么程度？”等问题。例句：“她唱得很动听。”
Pronoun: A word that takes the place of a noun (I, you, he, she, it, we, they). Possessive pronouns (mine, yours, hers) show ownership without an apostrophe.
代词：替代名词的词（我、你、他、她、它、我们、他们）。物主代词（我的、你的、她的）表示所有格，不加撇号。
Preposition: A word that shows the relationship between a noun (or pronoun) and another word in the sentence, often indicating time, place, or direction. Examples: in, on, at, under, between.
介词：表示名词（或代词）与句中另一词之间关系的词，常指示时间、地点或方向。如：在……里面、在……上面、在……下面、之间。
Conjunction: A word that joins words, phrases, or clauses. Coordinating (FANBOYS), subordinating (because, although), and correlative (either...or) conjunctions are key.
连词：连接词、短语或分句的词。并列连词（FANBOYS）、从属连词（因为、虽然）和关联连词（要么……要么）都很关键。
Interjection: A word or phrase that expresses strong emotion or surprise. Often followed by an exclamation mark. Example: 'Wow! That is incredible.'
感叹词：表达强烈情绪或惊讶的词或短语。通常后接感叹号。例句：“哇！这太不可思议了。”
4. Tense Formulas | 时态公式
Tenses locate actions in time. English has three primary times (past, present, future) with four aspects each, but Year 9 focuses on key formulas.
时态将动作定位于时间之中。英语有三大时间（过去、现在、将来），每个包含四个体，但 Year 9 着重于几个关键公式。
Present Simple: Subject + base verb (+ -s/-es for third person singular). Used for habits, facts, and scheduled events. Example: 'She walks to school every day.'
一般现在时：主语 + 动词原形（第三人称单数加 -s/-es）。用于习惯、事实和安排好的事件。例句：“她每天步行上学。”
Present Continuous: Subject + am/is/are + present participle (-ing). Used for actions happening now or around now. Example: 'I am reading a fascinating novel.'
现在进行时：主语 + am/is/are + 现在分词（-ing）。用于此刻或当前阶段正在进行的动作。例句：“我正在读一本精彩的小说。”
Past Simple: Subject + past form of verb (regular -ed, irregular forms). Used for completed actions at a specific time in the past. Example: 'They visited the museum yesterday.'
一般过去时：主语 + 动词过去式（规则加 -ed，不规则变化）。用于过去某一特定时间完成的动作。例句：“他们昨天参观了博物馆。”
Present Perfect: Subject + has/have + past participle. Links a past action to the present; used for experiences or continuing situations. Example: 'She has lived here since 2019.'
现在完成时：主语 + has/have + 过去分词。将过去的动作与现在联系起来；用于表达经历或持续至今的情况。例句：“自2019年以来她就住在这里。”
Future with 'will': Subject + will + base verb. Used for predictions, spontaneous decisions, and promises. Example: 'I will help you with your homework.'
一般将来时（用 will）：主语 + will + 动词原形。用于预测、即时决定和承诺。例句：“我会帮你做家庭作业。”
Past Progressive: Subject + was/were + present participle (-ing). Used for actions that were in progress at a particular past moment, often interrupted. Example: 'I was watching TV when the phone rang.'
过去进行时：主语 + was/were + 现在分词（-ing）。用于过去某一特定时刻正在进行的动作，常被打断。例句：“电话响的时候我正在看电视。”
5. Paragraph Writing Formula | 段落写作公式
A well-structured paragraph follows a reliable formula that builds a logical argument or description. The PEEL method is one of the most effective patterns.
结构良好的段落遵循一个可靠的公式，能构建出有逻辑的论证或描写。PEEL 模式是最有效的方法之一。
PEEL Formula: Point + Evidence + Explanation + Link. Begin with a clear topic sentence (Point), support it with a quotation or specific detail (Evidence), explain how the evidence supports the point (Explanation), then connect back to the question or forward to the next paragraph (Link).
PEEL 公式：观点 + 证据 + 解释 + 链接。以清晰的主题句（观点）开头，然后用引文或具体细节（证据）支撑，解释证据如何支撑观点（解释），最后回扣题目或过渡到下一个段落（链接）。
Point Formula: Your topic sentence must directly answer the essay question and present one clear argument. Example: 'The author creates a tense atmosphere through vivid sensory imagery.'
观点公式：主题句必须直接回答作文题目，提出一个清晰的论点。例句：“作者通过生动的感官意象营造了紧张的氛围。”
Evidence Formula: Embed a short quotation or refer to a precise detail from the text. Always use quotation marks for direct speech and cite the source. Example: 'The biting wind slashed through the streets' illustrates the harsh setting.
证据公式：嵌入短小的引文或引用文本中的精准细节。直接引语务必使用引号并注明出处。例句：“‘刺骨的寒风穿过街巷’ 这一描写展现了严酷的环境。”
Explanation Formula: Zoom in on key words or techniques. Ask 'how' and 'why' the evidence works. Use phrases like 'This suggests...', 'The word ... implies...', or 'This technique highlights...'
解释公式：聚焦关键词或技巧。问自己证据“如何”起效、“为什么”有效。使用诸如“这表明……”“这个词意味着……”“这一手法凸显了……”等短语。
Link Formula: Summarise how the paragraph supported your overall argument or create a transition. Example: 'Thus, the writer's choice of imagery not only sets the scene but also builds anticipation for the conflict ahead.'
链接公式：总结段落如何支撑整体论点，或进行过渡。例句：“由此可见，作者对意象的选择不仅设定了场景，还为即将到来的冲突做了铺垫。”
6. Figurative Language Formulas | 修辞手法公式
Writers use figurative language to create imagery and convey deeper meaning. These 'formulas' describe how comparisons and sound devices are constructed.
作家运用修辞手法创造意象并传达深层含义。这些“公式”描述了比较和声音装置是如何构建的。
Simile Formula: A is like B or A is as ... as B. Uses 'like' or 'as' to compare two unlike things. Example: 'The night was as dark as coal.'
明喻公式：A 像 B 或 A 和 B 一样……。用“像”或“和……一样”来比较两个不同的事物。例句：“夜晚像煤炭一样黑。”
Metaphor Formula: A is B. Directly states one thing is another to highlight a shared quality. Example: 'Time is a thief.'
暗喻公式：A 是 B。直接将一事物说成是另一事物，以凸显共同品质。例句：“时间是个小偷。”
Personification Formula: Non-human object + human action or quality. Give an inanimate object feelings or behaviour. Example: 'The wind whispered through the trees.'
拟人公式：非人体对象 + 人的动作或品质。赋予无生命物体以情感或行为。例句：“风在树间低语。”
Onomatopoeia Formula: Word = sound it represents. The spelling mimics the actual sound. Example: 'Buzz', 'Sizzle', 'Thump'. It adds auditory imagery to your writing.
拟声词公式：词 = 其所代表的声音。拼写模仿实际声响。例：“嗡嗡”“咝咝”“砰”。它为写作增添听觉意象。
Hyperbole Formula: Extreme exaggeration for effect, not to be taken literally. Example: 'I have told you a million times.' It intensifies emotion or creates humour.
夸张公式：极度的夸大，用于取得效果而非字面理解。例句：“我跟你说了一百万遍了。”它能强化情感或制造幽默。
Alliteration Formula: Repeated initial consonant sound in two or more nearby words. Example: 'Peter Piper picked a peck of pickled peppers.' It creates rhythm and memorability.
头韵公式：重复的起始辅音，出现在两个或多个相邻单词中。例句：“Peter Piper picked a peck of pickled peppers.” 它制造节奏和记忆点。
7. Reading Comprehension Strategy | 阅读理解策略
Tackling unseen texts becomes formulaic with active reading strategies. Use this systematic approach to extract meaning efficiently.
运用主动阅读策略，应对陌生文本便有了章法。使用这一系统方法可高效提炼意义。
Skim First: Glance over headings, first and last paragraphs, and topic sentences to get the gist. This gives you a mental map of the text in under a minute.
先略读：浏览标题、首末段和主题句以获取大意。这能在一分钟内给你一份文本的思维地图。
Scan for Details: Look for keywords from the question. Move your eyes quickly to locate dates, names, or specific terminology. Highlight or underline them.
扫读细节：寻找问题中的关键词。快速移动视线以定位日期、名字或特定术语。用高亮或下划线标出。
Question the Text: While reading, ask 'who, what, where, when, why, and how' about the content. Formulate your own questions to predict what comes next.
对文本提问：阅读时，对内容提问“谁、什么、哪里、什么时候、为什么、怎样”。自行提出问题以预测后续内容。
Inference Formula: Textual Clue + Background Knowledge = Inference. Combine what the author states with what you already know to read between the lines. Example: 'She grabbed her umbrella and put on boots' infers it is raining, even if not stated.
推论公式：文本线索 + 背景知识 = 推论。将作者所写与你已知的信息结合，读出言外之意。例句：“她抓起雨伞穿上雨靴” 可推知正在下雨，即便文中未明说。
Summarise Promptly: After each paragraph, pause and state the main idea in one sentence. Use key words from the text but in your own phrasing. This boosts long-term understanding.
即时总结：每读完一段，暂停并用一句话陈述大意。使用文本关键词但以自己语言表述。这有助于长期理解。
8. Spelling Patterns | 拼写模式
English spelling follows patterns, though exceptions exist. Learn these reliable 'formulas' to improve written accuracy.
英语拼写虽有例外，但遵循规律。学习这些可靠的“公式”以提高书面准确性。
I before E Formula: I before E except after C, when the sound is 'ee'. Examples: believe, receive, ceiling. Exceptions include weird, seize, protein.
I 在 E 前公式：除在 C 后外，I 在 E 之前，当发音为长音 ee 时。例子：believe, receive, ceiling。例外包括 weird, seize, protein。
Dropping E Formula: When adding a suffix beginning with a vowel to a word ending in silent e, drop the e ope → hoping, fame → famous. Keep the e if suffix starts with a consonant: hope → hopeful.
去 E 公式：当在以不发音 e 结尾的单词后添加以元音开头的后缀时，去掉 e。例：hope → hoping, fame → famous。若后缀以辅音开头则保留 e：hope → hopeful。
Doubling Consonant Formula: In one-syllable words with a short vowel followed by a single consonant, double the final consonant bigger. For longer words, double if the stress is on the last syllable: begin → beginning.
双写辅音公式：对于短元音后接单辅音的单音节单词，在添加 -ing、-ed、-er、-est 前双写词尾辅音。例：run → running, big → bigger。多音节词若重音在最后音节则双写：begin → beginning。
Plural Formula: Most nouns simply add -s. Add -es ant + y, change y to i and add -es: baby → babies. For vowel + y, just add -s: boy → boys.
复数公式：大多数名词直接加 -s。若词尾为 -s、-ss、-sh、-ch、-x、-z，则加 -es。例：bus → buses。若词尾为辅音 + y，变 y 为 i 再加 -es：baby → babies。若词尾为元音 + y，直接加 -s：boy → boys。
