2. Basic Sentence Structure | 基本句子结构
Subject + Verb + Object = Simple Sentence
The simplest complete sentence has a subject and a predicate. Example: The dog barks. Adding an object gives more information: The boy kicked the ball.

并列句用并列连词连接两个独立分句。例如：我想去，但是下雨了。
A complex sentence contains one independent clause and at least one dependent clause. Example: Although it was cold, we went to the park.
复合句包含一个独立分句和至少一个从属分句。例如：虽然天很冷，我们还是去了公园。
| Structure | Formula | Example |

| Simple | S + V (+ O) | Birds fly. |
| Compound | Independent + Coordinating Conjunction + Independent | She laughed and he smiled. |
| Complex | Independent + Subordinating Conjunction + Dependent | We stayed home because it rained. |
3. Tenses Formula Table | 时态公式表
Mastering tenses helps you locate events precisely in time. The table below summarises the most common tense structures for Year 8.
掌握时态能帮助你精确地定位事件发生的时间。下表总结了 Year 8 最常见的时态结构。
| Tense | Affirmative Formula | Example |

4. Punctuation Rules | 标点规则
A full stop (.) ends a declarative sentence. Always place it directly after the last word with no space before.
句号 (.) 用于结束陈述句。直接跟在最后一个单词后，前面不留空格。
A comma (,) separates items in a list or clauses. I bought apples, bananas, and pears. It also sets off introductory phrases.
逗号 (,) 分隔列表中的项目或分句。我买了苹果、香蕉和梨。它也用于隔开引导性短语。
An apostrophe (') shows possession or contraction. Sarah's bag (possession); don't (do not). Be careful not to use an apostrophe for plurals.
撇号 (') 表示所有格或缩写。Sarah's bag（所有格）；don't（不要）。注意，不要把撇号用于普通复数。
Quotation marks ('...' or "...") enclose direct speech. She said, 'Hello.' Commas and full stops go inside the closing quotation mark.

A question mark (?) comes at the end of a direct question. What time is it? Do not use it with indirect questions.

An exclamation mark (!) expresses strong emotion or commands. Use it sparingly to keep writing effective.

6. PEEL Paragraph Formula | PEEL 段落公式
P + E + E + L = Perfect Analytical Paragraph
Point: Start with a clear topic sentence that states your main idea. It tells the reader what the paragraph will be about.
观点：用一个明确的主题句开篇，陈述你的主要观点，让读者知道本段要讲什么。
Evidence: Provide a quotation or specific example from the text to support your point. Always embed your evidence smoothly.
证据：从文本中引用原文或给出具体例子支撑你的观点，并确保证据自然地融入文中。

Example PEEL para: (P) Shakespeare presents Macbeth as ambitious. (E) He says, 'I have no spur to prick the sides of my intent, but only vaulting ambition.' (E) The metaphor of 'vaulting ambition' compares his desire to a horse that overleaps itself, suggesting his ambition will cause his downfall. (L) This ambition drives the tragedy from the very start.
PEEL 段落示例：(P) 莎士比亚把麦克白塑造得野心勃勃。(E) 他说：‘我除了翻腾的野心之外，没有什么激励我意图的马刺。’ (E) ‘翻腾的野心’这一隐喻将他的欲望比作跳得过高的马，暗示野心会导致他的毁灭。(L) 从故事一开始，这种野心就推动了悲剧发展。
7. Narrative Structure | 叙事结构
Every story follows a pattern. Knowing the narrative formula helps you analyse texts and plan your own stories.

结局：冲突得以解决，线索收束，故事得到一个令人满意的结尾。
| Orientation | Once upon a time in a dark forest... |
| Complication | Suddenly, a fierce dragon appeared. |
| Climax | The knight charged and plunged his sword. |
| Resolution | The dragon was defeated, and peace returned. |

AFOREST is a powerful acronym to remember persuasive devices. Use them to argue effectively in speeches, letters and essays.
AFOREST 是记忆说服手法的有力缩写，用于在演讲、书信和议论文中进行有效论证。
A – Alliteration: Catchy repetition of sounds makes a phrase memorable. Example: stress-free, safe and sound.

F – Facts: Use statistics or verifiable information to support your argument. Example: 70% of teenagers agree...
F – 事实：用数据或可验证的信息支持论点。例如：70% 的青少年同意……
O – Opinions: Expert or personal opinions add weight. Example: Dr Evans states that...
O – 观点：专家或个人观点增加分量。例如：Evans 博士指出……

9. Reading Comprehension Strategies | 阅读理解策略
Skimming means reading quickly to get the general idea. Look at headings, first lines and key words.
略读是指快速阅读以获取大意。看标题、首句和关键词。
Scanning is looking for specific information, such as a name or date. Move your eyes rapidly over the text until you find the detail.
扫读是寻找特定信息，如人名或日期。视线快速扫过文本，直到找到细节。
Inference (reading between the lines) uses clues in the text + your own knowledge to understand what is not directly stated. Example: She shivered and pulled her coat tighter → It is cold.
推断（读出言外之意）结合文中的线索和你自己的知识，去理解未直接陈述的内容。例如：她发抖并把外套裹得更紧 → 天冷。
Identifying the writer's purpose helps you answer 'why' questions. The main purposes are to inform, persuade, entertain or describe (IPED).
识别作者写作目的帮你回答‘为什么’类问题。主要目的有：告知、说服、娱乐或描述。
Using context clues can help you guess the meaning of unfamiliar words. Look at prefixes, suffixes and surrounding sentences.
利用上下文线索能帮你猜出不熟悉单词的意思。观察词缀、后缀和周围的句子。
Summary writing requires selecting only the main points and paraphrasing them in your own words, keeping the original meaning.
写概要需要只挑出主要观点，用自己的话转述，同时保持原意不变。
10. Common Grammar Mistakes to Avoid | 常见语法错误避坑
Your vs. You're: 'Your' shows possession (your book). 'You're' is short for 'you are'. Test it by replacing with 'you are'.
Your 与 You're：‘Your’表示所有格（你的书）。‘You’re’是‘you are’的缩写。用‘you are’替换试试看。
Their / There / They're: 'Their' = possession. 'There' = place. 'They're' = they are. Always check.
Their / There / They're：‘Their’= 所有格。‘There’= 地点。‘They’re’= they are。务必检查。
Subject-verb agreement: The verb must match the subject in number. She walks (singular), They walk (plural). Watch out for long phrases between subject and verb.
主谓一致：动词必须在数上与主语一致。她走 (单数)，他们走 (复数)。小心主语和动词之间的长修饰语。
Double negatives: Using two negatives makes a weak positive. Avoid 'I don't have no time' → 'I have no time' or 'I don't have any time'.
双重否定：两个否定词会变成弱肯定。避免‘我没有没有时间’，应说‘我没有时间’或‘我没时间’。
Run-on sentences: Do not join two independent clauses with only a comma (comma splice). Use a full stop, semicolon or conjunction.
连写句：不要只用逗号连接两个独立分句（逗号拼接）。使用句号、分号或连词。
Inconsistent tense: Keep your tense the same unless the meaning requires a shift. He walked home and eats dinner (incorrect) → He walked home and ate dinner.
时态不一致：除非意义需要，否则保持时态一致。他走路回家然后吃晚饭（错）→ 他走路
