1. Reading Comprehension: Identifying Main Ideas and Supporting Details | 阅读理解: 识别主旨与支撑细节
When you read a passage, the main idea is the most important point the writer wants to communicate. Often it appears in the first or last sentence of a paragraph, but sometimes you must sum it up in your own words. Look for repeated keywords and ask yourself: what is the overall message?
阅读文章时，主旨大意是作者想要表达的最重要观点。它通常出现在段落的首句或末句，但有时你需要用自己的话进行概括。寻找重复出现的关键词，并问自己：整体信息是什么？
Supporting details are facts, examples, or descriptions that explain and strengthen the main idea. They might include statistics, anecdotes, sensory details, or reasons. When you answer comprehension questions, always connect your answer back to the main idea and show which details support it.
支撑细节是解释和强化主旨的事实、例子或描述。它们可能包括统计数据、轶事、感官细节或理由。在回答阅读理解题时，始终将答案与主旨联系起来，并说明哪些细节作为支撑。
Practise by highlighting the topic sentence in each paragraph, then listing the supporting points in a simple table. This helps you see how writers build logical arguments and smooth explanations.
练习时，在每个段落中找出主题句并高亮，然后用简单表格列出支撑点。这能帮助你了解作者如何构建逻辑论证和流畅的解释。
2. Inference and Deduction: Reading Between the Lines | 推断与演绎: 读懂言外之意
Writers do not always state everything directly. Inference means using clues from the text plus your own background knowledge to work out something that is not openly said. For instance, if a character’s hands tremble and she keeps looking at the clock, you can infer she is nervous or waiting for something important.
作者并不总是直接说出所有内容。推断是指利用文中的线索并结合你自己的背景知识，得出文中没有明说的内容。例如，如果一个人物双手颤抖，不断看钟，你可以推断出她紧张或正在等待重要的事情。
Deduction is a more logical form of reasoning. When you deduce, you apply general rules to specific situations in the text. If a story says 'All students who missed the bus received a warning' and you read that Tom missed the bus, you can deduce that Tom probably received a warning.
演绎是一种更具逻辑性的推理方式。当你进行演绎时，你将一般规则应用于文中的具体情境。如果故事说“所有错过校车的学生都收到了警告”，而你又读到汤姆错过了校车，你就可以演绎出汤姆很可能收到了警告。
Always support your inferences with evidence from the text. A good answer says, 'I can infer that… because the text says…' This shows the examiner you are not just guessing but reading carefully.
始终用文中的证据支持你的推断。好的答案会说：“我可以推断出…… 因为文中说……”。这表明你不是随意猜测，而是在认真阅读。
3. Vocabulary in Context: Understanding Unfamiliar Words | 语境词汇: 理解生词
You will meet many unfamiliar words in Year 7 texts. Instead of skipping them, use context clues. Look at the words and sentences around the unknown word. Synonyms, antonyms, explanations in brackets, or examples can all give away the meaning.
在 Year 7 的文本中你会遇到许多生词。不要跳过它们，而要利用语境线索。查看生词周围的词语和句子。同义词、反义词、括号中的解释或例子都可以揭示其含义。
Understand root words, prefixes, and suffixes. For example, the prefix 'un-' means not, so 'unfamiliar' means not familiar. The suffix '-ful' means full of, so 'careful' means full of care. This knowledge can expand your vocabulary rapidly.
理解词根、前缀和后缀。例如，前缀 'un-' 表示“不”，因此 'unfamiliar' 的意思是“不熟悉的”。后缀 '-ful' 表示“充满”，因此 'careful' 的意思是“充满关怀”。掌握这些知识可以迅速扩展你的词汇量。
Use a monolingual dictionary to check definitions, and always write down a new word in a personal vocabulary bank with its word class, definition, and an example sentence. The more you use a word, the better you remember it.
用单语词典查词义，并坚持在新词本中记录生词，包含词性、释义和例句。你使用一个词的次数越多，记忆就越牢固。
4. Grammar Fundamentals: Parts of Speech and Sentence Structure | 语法基础: 词性与句子结构
Solid grammar underpins everything you write. In Year 7, you must confidently identify and use the eight main parts of speech: nouns, pronouns, verbs, adjectives, adverbs, prepositions, conjunctions, and interjections. Every word in a sentence belongs to one of these classes.
扎实的语法是一切写作的基础。在 Year 7，你必须能自信地识别和使用八大词性：名词、代词、动词、形容词、副词、介词、连词和叹词。句子中的每个词都属于这几种词类之一。
Recognise simple, compound, and complex sentences. A simple sentence has one independent clause (e.g. 'The cat slept.'). A compound sentence joins two independent clauses with a coordinating conjunction (e.g. 'The cat slept, and the dog barked.'). A complex sentence contains an independent clause and at least one dependent clause (e.g. 'While the cat slept, the dog barked.').
学会识别简单句、并列句和复合句。简单句含有一个独立分句（例如 'The cat slept.'）。并列句用并列连词连接两个独立分句（例如 'The cat slept, and the dog barked.'）。复合句含有一个独立分句和至少一个从属分句（例如 'While the cat slept, the dog barked.'）。
Varying your sentence types makes your writing more engaging. Too many simple sentences sound choppy; too many long complex sentences can confuse your reader. Aim for a balance.
变换句型能让你的写作更吸引人。太多的简单句听上去断断续续，而过多的长复合句又会让读者感到混乱。要做到两者平衡。
5. Tenses and Verb Forms: Present, Past, and Future | 时态与动词形式: 现在、过去与将来
Your choice of tense shows when an action happens. The three main tenses in English are present, past, and future. Each has simple, continuous (progressive), perfect, and perfect continuous forms, giving at least twelve possibilities. In Year 7, focus on using the simple and continuous forms accurately first.
时态的选择体现动作发生的时间。英语的三大基本时态是现在、过去和将来。每个时态又分为一般、进行、完成和完成进行四种形式，因此至少有十二种可能。在 Year 7，首先要准确使用一般时和进行时。
The simple present describes habits and general truths (e.g. 'She walks to school.'). The present continuous talks about actions happening right now (e.g. 'She is walking to school.'). The simple past narrates completed actions (e.g. 'She walked to school.'). The past continuous describes actions that were in progress at a specific past time (e.g. 'She was walking to school when it started to rain.').
一般现在时描述习惯和普遍真理（例如 'She walks to school.'）。现在进行时谈论此刻正在发生的动作（例如 'She is walking to school.'）。一般过去时叙述已完成的动作（例如 'She walked to school.'）。过去进行时描述在过去某一特定时刻正在进行的动作（例如 'She was walking to school when it started to rain.'）。
Be careful with irregular past forms like 'go → went', 'buy → bought', and 'write → wrote' list of common irregular verbs and testing yourself regularly will build your confidence.
注意不规则动词的过去式，如 'go → went', 'buy → bought', 'write → wrote'。列出常见的不规则动词并经常自测，可以增强你的信心。
6. Punctuation and Capitalisation: Full Stops, Commas, and Apostrophes | 标点与大小写: 句号、逗号与撇号
Correct punctuation clarifies meaning. The full stop (.) marks the end of a sentence. Capital letters start every sentence and all proper nouns, such as names, places, days, and months. Without these basics, writing becomes confusing.
正确的标点能让意思清晰。句号 (.) 标示一个句子的结束。大写字母用于每个句子开头以及所有专有名词，如人名、地名、星期和月份。没有这些基础，文章就会变得难以理解。
Commas (,) separate items in a list, connect two clauses with a coordinating conjunction, or set off introductory words. Do not overuse commas to join two independent clauses without a conjunction; that creates a comma splice, which should be avoided.
逗号 (,) 用来分隔句中所列举的项目、用并列连词连接两个分句，或引出开头的词语。不要滥用逗号在没有连词的情况下连接两个独立分句，那样会形成逗号拼接的错误，应当避免。
Apostrophes (') have two main uses: showing possession (e.g. 'Sara’s book') and indicating contractions or omitted letters (e.g. 'don’t' for 'do not'). Never use an apostrophe before an 's' to form a simple plural; write 'the books are here,' not 'the book’s are here.'
撇号 (') 有两项主要用途：表示所有格（例如 'Sara’s book'）和表示缩写或字母省略（例如 'don’t' 代替 'do not'）。切勿在构成简单复数时在 's' 前加撇号，正确的写法是 'the books are here' 而不是 'the book’s are here'。
7. Spelling Rules and Common Errors | 拼写规则与常见错误
Accurate spelling is a vital skill. Learn key rules such as 'i before e except after c when the sound is ee' (e.g. 'believe' vs. 'receive'). For words ending in a silent 'e', drop the 'e' before adding a vowel suffix (e.g. 'make' → 'making'), but keep it before a consonant suffix (e.g. 'care' → 'careful').
准确的拼写是一项关键技能。要学习重要规则，比如“i 在 e 之前，除非在 c 之后且发 ee 的音”（例如 'believe' 和 'receive'）。对于以不发音 'e' 结尾的词，在加元音后缀时需去掉 'e'（例如 'make' → 'making'），而在加辅音后缀时则保留 'e'（例如 'care' → 'careful'）。
Study common homophones carefully because spellcheckers will not catch them. Pairs like 'their/there/they’re', 'your/you’re', and 'to/too/two' are consistently tested. Make mnemonic sentences to remember which form fits which meaning.
仔细学习常见的同音异义词，因为拼写检查器无法发现它们。像 'their/there/they’re'、'your/you’re' 和 'to/too/two' 这样的组合经常出现在考试中。可以编造记忆法句子来记住哪种形式对应哪种意义。
Avoid common mistakes such as doubling consonants unnecessarily or forgetting to change 'y' to 'i' before some suffixes (e.g. 'happy' → 'happily' ad your work by reading it aloud backwards, word by word, to focus purely on the spelling.
避免常见错误，比如不必要的双写辅音或在某些后缀前忘记将 'y' 改为 'i'（例如 'happy' → 'happily'）。校对时可以从后往前逐词大声朗读，以便将注意力完全放在拼写上。
8. Writing for Purpose: Narrative and Descriptive Texts | 目的性写作: 叙事与描述文
Writers shape their language according to purpose and audience. Two key text types in Year 7 are narrative and descriptive writing. Narratives tell a story with a clear sequence of events, while descriptive texts create vivid pictures of people, places, or objects.
作者根据写作目的和读者来调整语言。Year 7 的两种关键文本类型是叙事文和描写文。叙事文讲述一个具有清晰事件顺序的故事，而描写文则生动地描绘人物、地点或物体。
In a narrative, structure your plot with an opening that introduces characters and setting, a build-up, a climax where the main problem peaks, and a resolution. Use dialogue, varied sentence starters, and powerful verbs to maintain interest.
在叙事文中，情节结构应包括开头（介绍人物和背景）、发展、高潮（主要矛盾达到顶点）和结局。利用对话、多样化的句子开头和有力的动词来保持读者的兴趣。
Descriptive writing relies on sensory details. Use the five senses: what can you see, hear, smell, touch, and taste? Select precise adjectives and adverbs, and organise your description from general to specific or from left to right for a clear spatial order.
描写文依靠感官细节。运用五种感官：你看到、听到、闻到、触到和尝到了什么？选择精确的形容词和副词，并按照从整体到局部或从左到右的顺序来组织描写，以获得清晰的空间感。
9. Planning and Structuring Your Writing: Paragraphs and Cohesion | 写作规划与结构: 段落与衔接
Good writing rarely happens in one draft. Always plan before you write: brainstorm ideas, group related points, and create a brief outline. A typical structure includes an engaging introduction, several body paragraphs each focused on one main idea, and a conclusion that sums up or reflects.
好的写作很少能在一次草稿中完成。写作前始终要进行规划：头脑风暴列出想法，将相关要点归类，并拟一个简要大纲。典型的结构包括引人入胜的开头、几个主体段落（每段集中阐述一个主要观点）以及总结或反思的结尾。
Each body paragraph should begin with a topic sentence, followed by supporting sentences and a final linking or concluding sentence. Cohesive devices such as conjunctions (because, although), pronouns for referring back, and time connectives (meanwhile, later) help your writing flow smoothly.
每个主体段落应以主题句开头，接着是支撑句，最后以衔接或结论句收尾。衔接手段如连词（因为、虽然）、用于前指的代词以及时间连接词（与此同时、后来）有助于文章流畅推进。
After drafting, always revise for clarity and style. Check that your paragraphs link logically. If you find a sudden jump, add a transition word. Reading your work aloud reveals awkward phrasings and missing links more effectively than silent reading does.
完成草稿后，一定要修改以保证清晰度和文体。检查段落之间是否能够逻辑衔接。如果发现有突然的跳跃，就添加过渡词。大声朗读能比默读更有效地发现别扭的措辞和缺失的衔接。
10. Literary Devices: Simile, Metaphor, and Personification | 文学手法: 明喻、暗喻与拟人
Writers use literary devices to create imagery and emotional impact. A simile makes a direct comparison using 'like' or 'as', for example, 'The moon shone like a silver coin.' This helps readers visualise a mental picture by connecting something new to something familiar.
作者使用文学手法来营造意象和情感冲击。明喻使用 'like' 或 'as' 进行直接对比，例如 'The moon shone like a silver coin.'（月亮像一枚银币般闪耀）。这通过将新事物与熟悉事物联系起来，帮助读者在脑海中形成画面。
A metaphor states that one thing is another, without using 'like' or 'as', creating a stronger, more emphatic connection. For instance, 'The room was a furnace' suggests intense heat directly. When you analyse a metaphor, explain what qualities the writer is transferring.
暗喻 直接将一事物说成是另一事物，不使用 'like' 或 'as'，从而建立更强、更具强调性的联系。例如 'The room was a furnace'（房间是个火炉）直接暗示酷热。在分析暗喻时，需解释作者转移了哪些特质。
Personification gives human characteristics to non-human things. 'The wind whispered through the trees' makes the wind feel secretive and gentle. Recognising these devices improves reading comprehension, and using them appropriately adds flair to your own creative writing.
拟人 赋予非人类事物以人类的特征。“风在树间低语”让风显得神秘而轻柔。识别这些手法能提高阅读理解能力，而恰当地运用它们则能为你的创意写作增添文采。
Look for these devices in poetry and fiction extracts. Ask yourself why the writer chose a specific image and what mood or meaning it creates. Then try crafting your own examples in a writing exercise book.
在诗歌和小说选段中寻找这些手法。问问自己作者为什么选择特定的意象，它营造了怎样的氛围或意义。然后试着自己的写作练习本中创作一些例子。
