"Finding the main idea"
Identifying the central point or argument the author wants to convey in a paragraph or passage.
"The main idea of the article is that regular exercise improves mental health, not just physical fitness."
"Identifying supporting details"
Locating specific facts, examples, or reasons that back up the main idea.
"Each paragraph provides a supporting detail: statistics, expert quotes, and real-life cases."
"Making inferences"
Drawing conclusions about information the author implies but does not state directly.
"Although the text never says she was nervous, we infer it from her shaking hands and short answers."
"Drawing conclusions"
Using stated evidence and logic to form a judgment about something beyond the text.
"From the data presented, we can draw the conclusion that the project was underfunded from the start."
"Distinguishing fact from opinion"
Recognising whether a statement can be verified objectively or reflects personal belief.
"'The study took five years' is a fact; 'the results are disappointing' is an opinion."
"Understanding sequence"
Following the order of events or steps as presented in a text.
"Read the instructions in sequence — mixing the ingredients before preheating the oven will ruin the recipe."
"Recognising cause and effect"
Identifying why something happened and what resulted from it in a passage.
"The cause was the sudden frost; the effect was a 40% loss in the harvest."
"Paraphrasing"
Restating a sentence or passage in your own words while keeping the original meaning.
"Instead of copying the definition, she paraphrased it: 'It means the ability to bounce back after setbacks.'"
"Previewing"
Scanning headings, subheadings, images, and introductory sentences before reading the full text.
"Spend two minutes previewing the chapter — read the title, headings, and bold terms — before you start."
"Predicting"
Forming expectations about what a text will discuss based on its title, visuals, or first paragraph.
"Before reading, predict what the article is about: the title 'Ice Caps Shrink Again' suggests climate news."
"Skimming"
Reading quickly over a text to get a general sense of its topic and structure without reading every word.
"Skim the report first to find the sections relevant to your question, then read those closely."
"Scanning"
Moving your eyes rapidly through a text to locate a specific piece of information such as a date or name.
"Scan the page for the year 1945 — you're not reading every sentence, just hunting for that number."
"Close reading"
Careful, detailed analysis of a short passage, paying attention to word choice, tone, and structure.
"Close reading the opening paragraph revealed three ironic phrases the author used to undermine the hero."
"Annotating"
Writing notes, questions, or reactions in the margins or on a digital document as you read.
"She annotated every paragraph: circling unknown words and writing 'why?' next to confusing claims."
"Questioning while reading"
Asking yourself questions about the text — who, what, why, how — to stay actively engaged.
"As you read each section, ask: What is the author's purpose here? Does the evidence support the claim?"
"Visualising"
Creating mental images or diagrams to represent information described in the text.
"Visualise the water cycle diagram as you read the description — picture the clouds, rain, and rivers."
"Context clues"
Words or phrases near an unknown word that hint at its meaning — definitions, synonyms, antonyms, or examples.
"The word 'arid', meaning extremely dry, is made clear by the context clue 'no rainfall for two years'."
"Definition clues"
When an author directly explains a term using phrases like "which means", "that is", or dashes.
"Photosynthesis — the process by which plants convert sunlight into food — occurs in the chloroplasts."
"Synonym clues"
A word nearby that means the same thing and helps clarify the meaning of the unfamiliar word.
"The terrain was rugged, or rough and uneven, making the hike exhausting."
"Antonym clues"
An opposite word or contrasting idea that helps narrow down what an unknown word means.
"Unlike his gregarious sister, Tom was taciturn — he rarely spoke at parties."
"Example clues"
Specific examples listed after an unknown word that reveal what category or concept it belongs to.
"Legumes, such as lentils, chickpeas, and beans, are an excellent source of protein."
"Word roots and affixes"
Using knowledge of prefixes, suffixes, and root words to guess the meaning of an unfamiliar word.
"Knowing that 'bio' means life and 'logy' means study makes 'biology' easy to decode."
"Tone and mood clues"
Using the emotional atmosphere of a passage to infer whether an unknown word is positive or negative.
"The celebratory tone of the paragraph tells you that 'elated' must mean something very positive."
"Re-reading for clarification"
Going back over a sentence or paragraph when meaning is unclear, rather than guessing immediately.
"If a sentence confuses you, re-read it slowly and look for the subject and main verb first."
"Chronological order"
Events or information arranged in the order they happened, often using time signal words.
"The biography follows chronological order: birth, childhood, career, and death."
"Compare and contrast"
A text structure that examines similarities and differences between two or more subjects.
"The essay uses compare and contrast to show how British and American English differ in spelling and vocabulary."
"Problem and solution"
The author describes a problem and then explains one or more ways to solve it.
"The article follows a problem-solution structure: rising sea levels are the problem; coastal barriers are the solution."
"Cause and effect"
A text pattern that explains why events happen and what consequences follow.
"The report uses cause and effect: deforestation causes soil erosion, which in turn leads to flooding."
"Description"
The author provides details, characteristics, or features of a topic without a strong argumentative structure.
"The travel piece is purely descriptive — it paints a vivid picture of the market without making any argument."
"Topic sentence"
The sentence, usually first, that states the main idea of a paragraph.
"Every paragraph begins with a clear topic sentence so the reader immediately knows what it is about."
"Transition words"
Words and phrases that link ideas and signal the relationship between them (however, therefore, in contrast).
"The word 'however' signals a contrast; 'therefore' signals a conclusion; 'for example' signals an illustration."
"Thesis statement"
A sentence in an essay's introduction that states the writer's central argument or position.
"The thesis statement — 'Social media is more harmful than beneficial for teenagers' — appears at the end of the first paragraph."
"Author's purpose"
The reason a writer creates a text — to inform, persuade, entertain, or describe.
"The author's purpose is to persuade; every paragraph pushes the reader toward a specific conclusion."
"Point of view"
The perspective from which a text is written — first person, third person, or an institutional voice.
"Written in first person, the memoir gives an intimate point of view; a third-person news report feels more objective."
"Tone and mood"
Tone is the author's attitude toward the subject; mood is the feeling the text creates in the reader.
"The sarcastic tone of the editorial signals the author's frustration; the anxious mood unsettles the reader."
"Bias and perspective"
Recognising how an author's background, values, or agenda might influence what they include or omit.
"The article only cites industry sources, which reveals a bias in favour of the company's position."
"Evaluating evidence"
Judging whether the facts, statistics, and examples given are sufficient and reliable to support a claim.
"The claim that 'most people agree' is unsupported — where is the survey data? The evidence is weak."
"Logical fallacies"
Errors in reasoning that weaken an argument, such as false dilemmas, ad hominem attacks, or slippery slopes.
"Saying 'If we allow this, society will collapse' is a slippery slope fallacy — the argument is not logical."
"Figurative language"
Non-literal expressions such as metaphors, similes, hyperbole, and personification that add depth to writing.
"'The exam was a mountain to climb' uses metaphor; 'I've told you a million times' uses hyperbole."
"Connotation vs. denotation"
The dictionary meaning of a word (denotation) versus its emotional or cultural associations (connotation).
"'Cheap' and 'affordable' both mean low-cost, but 'cheap' has a negative connotation while 'affordable' sounds positive."
"Academic texts"
Formal writing with specialised vocabulary, citations, and structured arguments found in textbooks and journals.
"Academic texts use passive voice and hedging language: 'It is suggested that' rather than 'We think'."
"News articles"
Journalistic writing with the most important information in the first paragraph, followed by supporting detail.
"An inverted pyramid structure means the news article's headline and first sentence carry the core facts."
"Fiction"
Imaginative prose such as novels and short stories that explore characters, plot, and theme.
"When reading fiction, pay attention to how character dialogue reveals personality and advances the plot."
"Persuasive texts"
Writing designed to change the reader's opinion or prompt action, using rhetorical techniques.
"Adverts and opinion columns are persuasive texts — look for emotive language, appeals to authority, and repetition."
"Instructions and procedures"
Texts that explain how to complete a task step by step, requiring close attention to sequence and detail.
"Read the full instructions before starting — the warning in step 7 affects how you complete step 2."
"Graphs, tables, and charts"
Visual information displays that accompany written text and must be read in relation to the surrounding data.
"The table shows the same trend the author describes — cross-reference the figures to confirm the claim."
"Online and multimodal texts"
Digital content that combines written text, hyperlinks, images, and video, requiring non-linear reading skills.
"Online reading demands that you evaluate each link and sidebar critically — not all connected content is reliable."
"Contracts and legal documents"
Formal documents with precise, binding language where every word has legal significance.
"In a contract, 'shall' means obligation while 'may' means permission — the distinction is legally critical."
よくある質問
英語の読解力とは何ですか？
読解力とは、テキストを読んでその意味を完全に理解する能力です。単に言葉を解読するだけでなく、主要なアイデア、補足的な詳細、暗示された意味、著者の意図を把握することです。予測、質問、要約などの戦略を通じてテキストに積極的に関与することを意味します。
英語の読解力を早く向上させるにはどうすればいいですか？
最も早い上達は、現在のレベルより少し上のテキスト（i+1インプット）を読むこと、読みながら積極的にメモを取ること、文脈の中で語彙を増やすこと、ニュース記事や短編小説、学術的な抜粋など多様なテキストで練習することから生まれます。毎日少なくとも20分の集中した読書を目標にしましょう。
最も重要な読解ストラテジーは何ですか？
最も効果的な戦略は、プレビュー（読む前にスキャン）、読みながら質問する、文脈から推論する、テキスト構造を特定する（原因・結果、比較・対比）、各セクション後に自分の言葉で要約することです。これらはすべてのテキストタイプと習熟度レベルに対応しています。
単語は個別に分かるのに、テキスト全体が理解できないのはなぜですか？
これは非常によくあることで、読解には語彙以上のもの — スキーマ（背景知識）、テキスト構造の理解、文をまたいでアイデアをつなぐ能力 — が必要だからです。解決策は、読むトピックについての背景知識を広げること、談話マーカーの識別を練習すること、多読を増やすことです。
IELTSやTOEFLなどの英語試験では読解力はどのようにテストされますか？
IELTSとTOEFLはどちらも、学術的なパッセージに続く選択式問題、True/False/Not given、マッチング、短答問題で読解力をテストします。具体的には主旨の特定、推論、文脈での語彙、著者の目的、テキスト構造をテストします。この6つのカテゴリーのスキルを練習することが試験の準備に直結します。
