1. Parts of Speech Overview | 词性概览
Every word belongs to one of eight parts of speech. Recognising them helps you build and vary sentences deliberately.
每个单词都属于八大词性之一。识别词性能帮助你刻意地构造和变换句子。
| Part | 词性 | Quick Rule | Example |
|---|---|---|---|
| noun | 名词 | names a person, place, thing or idea | courage, river, Maria |
| pronoun | 代词 | replaces a noun | she, they, it |
| verb | 动词 | shows action or state | is, run, imagine |
| adjective | 形容词 | describes a noun or pronoun | bright, curious, heavy |
| adverb | 副词 | describes a verb, adjective or another adverb | quickly, very, often |
| preposition | 介词 | shows relationship between a noun/pronoun and another word | in, on, after, under |
| conjunction | 连词 | joins words, phrases or clauses | and, but, because |
| interjection | 感叹词 | expresses strong emotion | Wow! Ouch! Oh! |
2. Sentence Formulas | 句子公式
Every main clause follows a predictable word-order pattern. Mastering these formulas lets you construct clear and grammatically accurate sentences.
每个主句都遵循一种可预测的语序模式。掌握这些公式能让你写出清晰且语法正确的句子。
Subject + Verb + Object + (Adverbial)
This is the basic declarative pattern. The subject performs the action; the verb describes it; the object receives it; optional adverbials supply extra detail.
这是陈述句的基本模式。主语发出动作；动词描述动作；宾语承受动作；可选的状语补充细节。
Subject + Verb + Complement
Use this formula when the verb is a linking verb (be, seem, become). The complement describes or identifies the subject.
当动词为系动词 (be, seem, become) 时使用此公式。补足语描述或指明主语。
Subordinating Conjunction + Clause , Main Clause
Complex sentences open with a dependent clause to show reason, time or condition.
复合句以从属连词引导的从句开头，表示原因、时间或条件。
3. Subject-Verb Agreement Rule | 主谓一致规则
A singular subject must have a singular verb; a plural subject must have a plural verb. The verb form changes mostly in the present simple tense.
单数主语必须搭配单数动词；复数主语搭配复数动词。动词形式主要在一般现在时中变化。
In the present simple, third-person singular subjects add an -s or -es to the base verb.
在一般现在时中，第三人称单数主语要求动词原形后加 -s 或 -es。
Collective nouns (team, family) may take a singular verb when the group acts as one unit, but a plural verb when individual members act separately.
集合名词 (team, family) 当整体行动时用单数动词，强调成员各自行动时可用复数动词。
Indefinite pronouns such as 'everyone' and 'nobody' are always singular.
不定代词如 everyone 和 nobody 总是单数。
4. Tense Formulae | 时态公式
Tense formulas encode when an action occurs and whether it is completed or ongoing. Here are the core CAIE Year 8 patterns.
时态公式编码了动作发生的时间以及它是完成还是进行中。以下是 Year 8 CAIE 核心模式。
Present Simple: Subject + base verb (+ -s/-es for third person singular)
For habits, facts and general truths. Signal words: always, every day, usually.
用于习惯、事实和普遍真理。标志词：always, every day, usually。
Present Continuous: Subject + am/is/are + verb-ing
For actions happening now or temporary situations. Signal words: now, at the moment, Look!
用于此刻正在发生的动作或临时状况。标志词：now, at the moment, Look!
Past Simple: Subject + verb-ed (irregular forms must be memorised)
For completed actions in the past. Signal words: yesterday, last week, in 2010.
用于过去完成的动作。标志词：yesterday, last week, in 2010。
Present Perfect: Subject + has/have + past participle
Links the past to the present; often used for experiences and recent events. Signal words: ever, never, just, already, yet.
连接过去与现在；常用于经历和最近的事件。标志词：ever, never, just, already, yet。
5. Punctuation Rules | 标点规则
Punctuation marks are the traffic signals of writing. These rules keep your reader moving in the right direction.
标点符号是写作中的交通信号。下面的规则能引导读者朝正确方向前进。
Full stops (.) end a complete declarative sentence.
句号 (.) 用于结束一个完整的陈述句。
Commas (,) separate items in a list, set off introductory clauses and enclose non-essential information.
逗号 (,) 分隔列表中的项目、隔开引导性从句以及包裹非必要信息。
Apostrophes (') show possession (Maria's book) or mark a contraction (do not → don't).
撇号 (') 表示所有 (Maria's book) 或构成缩略形式 (do not → don't)。
Quotation marks (" ") frame direct speech; the comma or full stop sits inside the closing quotation mark.
引号 (" ") 框起直接引语；逗号或句号位于后引号之内。
6. PEEL Paragraph Structure | PEEL 段落结构
PEEL is the go-to formula for analytical and persuasive paragraphs. It turns a general idea into a developed argument.
PEEL 是分析和论证段落的黄金公式，它将一个大意转变为展开的论证。
P + E + E + L → Point, Evidence, Explanation, Link
Point: State the topic sentence that signals what the paragraph will prove.
Point (观点)：写出提示段落论证方向的主题句。
Evidence: Quote or paraphrase a specific detail from the text.
Evidence (证据)：引用或改写文本中的具体细节。
Explanation: Analyse the evidence and show how it supports your point, using words like 'this suggests' or 'the writer implies'.
Explanation (解释)：分析证据并说明它如何支撑你的观点，使用 'this suggests' 或 'the writer implies' 等表达。
Link: Tie back to the question or connect to the next paragraph.
Link (连接)：回扣题目或过渡到下一段。
7. Figurative Language Quick Reference | 修辞语言速查
Figurative language makes writing vivid. You need to spot and explain it in reading tasks, and use it purposefully in your own writing.
修辞语言让文字生动。你需要在阅读任务中识别并解释它，并在自己的写作中有目的地运用。
| Device | 修辞手法 | Formula / Definition | Example |
|---|---|---|---|
| simile | 明喻 | compares two unlike things using 'like' or 'as' | as brave as a lion |
| metaphor | 暗喻 | says one thing IS another, without 'like' or 'as' | the classroom was a zoo |
| personification | 拟人 | gives human qualities to non-human things | the wind whispered |
| alliteration | 头韵 | repetition of the same initial sound in adjacent words | sizzling summer sun |
| onomatopoeia | 拟声 | word imitates the sound it describes | buzz, clang, sizzle |
| hyperbole | 夸张 | deliberate exaggeration for effect | I've told you a million times |
8. Comparatives & Superlatives | 比较级与最高级
Comparatives and superlatives follow clear formation formulas. Knowing them prevents common mistakes.
比较级和最高级的构成有明确公式。掌握它们可避免常见错误。
Short adjective (1 syllable): adj + -er → comparative | adj + -est → superlative
hort adjectives add -er and -est, with spelling adjustments (big → bigger, big → biggest).
短形容词加 -er 和 -est，注意拼写调整 (big → bigger, big → biggest)。
Long adjective (2+ syllables): more + adj → comparative | most + adj → superlative
Most adjectives of two or more syllables form the comparative with 'more' and the superlative with 'most'.
大多两个音节及以上的形容词用 'more' 构成比较级，'most' 构成最高级。
ves ending in -y change the y to i before adding -er or -est (happy → happier → happiest).
以 -y 结尾的双音节形容词，先变 y 为 i 再加 -er 或 -est (happy → happier → happiest)。
sed: good → better → best; bad → worse → worst; far → farther/further → farthest/furthest.
不规则形式需要记忆：good → better → best; bad → worse → worst; far → farther/further → farthest/furthest。
9. Direct & Indirect Speech | 直接引语与间接引语
Shifting between direct and indirect speech changes tense, pronouns and time expressions according to consistent rules.
在直接引语和间接引语之间转换时，时态、代词和时间状语会按照一致的规则发生变化。
Direct Speech: "Quoted words," reporting clause.
Enclose the exact words in quotation marks and separate the quoted speech from the reporting clause with a comma.
将原话用引号括起，并在引语与报道分句之间用逗号隔开。
Indirect Speech: reporting verb + (that) + shifted clause
When the reporting verb is in the past tense, the tense inside the reported clause moves one step back.
当报道动词为过去时，被报道从句中的时态向后倒退一步。
nt simple → past simple; present continuous → past continuous; past simple → past perfect; 'will' → 'would'; 'can' → 'could'.
一般现在时→一般过去时；现在进行时→过去进行时；一般过去时→过去完成时；will→would；can→could。
Time and place words also change: today → that day, tomorrow → the next day, here → there.
时间地点状语也需要变换：today → that day, tomorrow → the next day, here → there。
10. Homophones & Confusables | 同音词与易混词
Even small spelling mistakes can change meaning completely. Memorise the most frequently confused pairs.
再小的拼写错误也可能彻底改变意思。请记住这些最常被混淆的词对。
| Word | Meaning | 词 | 含义 |
|---|---|---|---|
| there | location or existence | there | 地点或存在 |
| their | belonging to them | their | 他们的 |
| they're | contraction of 'they are' | they're | 他们是 |
| your | belonging to you | your | 你的 |
| you're | contraction of 'you are' | you're | 你是 |
| its | belonging to it | its | 它的 |
| it's | contraction of 'it is' or 'it has' | it's | 它是/它有 |
| to / two / too | direction / number / also or excessive | to / two / too | 方向/数字/也或过于 |
11. Affixes: Prefixes & Suffixes | 词缀：前缀与后缀
Affixes change a word's meaning or part of speech. Recognising them helps you decode unfamiliar vocabulary.
词缀会改变单词的意思或词性。认识它们有助于你解码生词。
Prefix + Root → new meaning (often opposite or altered)
Common prefixes: un- (not), re- (again), pre- (before), dis- (opposite), mis- (wrongly).
常见前缀：un- (不), re- (再次), pre- (之前), dis- (相反), mis- (错误地)。
Root + Suffix → new part of speech
nt). Adjective suffixes: -ful, -less, -ous (hope → hopeful, hopeless; danger → dangerous).
名词后缀：-tion, -ness, -ment (act → action, kind → kindness, enjoy → enjoyment)。形容词后缀：-ful, -less, -ous (hope → hopeful, hopeless; danger → dangerous)。
Adverb suffix -ly often turns an adjective into an adverb: quick → quickly.
副词后缀 -ly 常将形容词变为副词：quick → quickly。
12. Reading Comprehension Cues | 阅读理解提示
Skilful readers use structural and linguistic cues to locate answers quickly. Treat these as your retrieval formulas.
熟练的读者会利用结构和语言线索快速定位答案。把这些当作你的信息检索公式。
Key Word + Scan = Quick Answer Location
Identify the main noun or verb from the question, then scan the text for that exact word or a synonym.
先圈出问题中的主要名词或动词，然后在文本中扫描该词或同义词。
Wh- question → specific information
→ thing or action; When → time/date; Where → place; Why → reason; How → manner or method.
Who → 人物；What → 事物或动作；When → 时间/日期；Where → 地点；Why → 原因；How → 方式或方法。
For inference questions, use the 'textual evidence + own knowledge' equation: quote a detail and add what you can figure out from it.
面对推理题，运用“文本证据 + 自身知识”这个等式：引用一处细节，再加上你由此推断出的内容。
Summarising follows the formula: main idea + supporting points + omit minor details.
摘要写作遵循公式：主旨 + 支撑要点 + 删去次要细节。
