コンテキストの文法

"present perfect vs. past simple"

Use the present perfect for experiences or recent actions connected to now; use past simple for finished events at a specific time.

"I've visited Tokyo three times" (experience) vs. "I visited Tokyo in 2019" (specific time).

コンテキストの文法

"third conditional"

Used to talk about hypothetical past situations and their imagined results. Structure: If + had + past participle, would have + past participle.

"If she had studied harder, she would have passed the exam."

コンテキストの文法

"reported speech"

Telling someone what another person said, shifting tenses back one step and changing pronouns and time expressions.

"She said she was tired" (reported from "I am tired").

コンテキストの文法

"passive voice"

Used when the focus is on the action or the object receiving the action, rather than who performed it.

"The new policy was announced yesterday" emphasises the policy, not who announced it.

コンテキストの文法

"relative clauses"

Clauses that give more information about a noun. Defining clauses identify which one; non-defining clauses add extra information.

"The book that I recommended won the prize" (defining) vs. "My sister, who lives in Paris, is visiting."

コンテキストの文法

"modal verbs for deduction"

Must, might, could, and can't used to express how certain you are about something in the present or past.

"She must be exhausted — she worked 14 hours today."

コンテキストの文法

"gerunds and infinitives"

Some verbs are followed by a gerund (-ing), some by an infinitive (to + verb), and some by either — sometimes with a change in meaning.

"I stopped smoking" (quit) vs. "I stopped to smoke" (paused in order to).

コンテキストの文法

"mixed conditionals"

Combining a past condition with a present result, or a present condition with a past result, to express complex hypothetical scenarios.

"If I had taken that job, I would be living in New York now."

語彙力強化

"collocation"

Words that naturally go together in English. Learning collocations rather than individual words makes your English sound far more natural.

"Make a decision" (not "do a decision"), "heavy rain" (not "strong rain").

語彙力強化

"word family"

A group of words formed from the same root, including different parts of speech. Knowing one word can help you learn four or five related forms.

Decide → decision → decisive → indecisive → decidedly.

語彙力強化

"false friends"

Words that look or sound similar to a word in your language but have a completely different meaning in English.

Spanish "embarazada" means pregnant, not embarrassed. Russian "магазин" means shop, not magazine.

語彙力強化

"register"

The level of formality in language. The same idea can be expressed formally, neutrally, or informally depending on the context.

"Commence" (formal), "begin" (neutral), "kick off" (informal) all mean to start something.

語彙力強化

"connotation"

The emotional or cultural meaning associated with a word, beyond its literal dictionary definition. Words can be positive, negative, or neutral in tone.

"Slim" and "skinny" both mean thin, but "slim" sounds positive while "skinny" often sounds negative.

語彙力強化

"prefix and suffix patterns"

Common word-building elements attached to the beginning (prefix) or end (suffix) of a word that change its meaning or part of speech.

Un- (unhappy), -tion (education), -ful (careful), re- (rewrite) — recognising these unlocks thousands of new words.

語彙力強化

"topic vocabulary clusters"

Grouping words by theme rather than learning random lists. This creates stronger memory connections and prepares you for real conversations.

For the topic "environment": emissions, deforestation, renewable energy, carbon footprint, sustainability, habitat.

語彙力強化

"spaced repetition"

A learning technique where you review vocabulary at increasing intervals, reviewing harder words more often and well-known words less often.

Review a new word after 1 day, then 3 days, then 1 week, then 2 weeks — this moves it to long-term memory.

句動詞とイディオム

"give up"

To stop trying to do something or to surrender a habit. One of the most common phrasal verbs in everyday English.

"She gave up trying to fix the printer and called the technician."

句動詞とイディオム

"put off"

To delay or postpone something, or to cause someone to dislike something.

"He keeps putting off going to the dentist because he finds it stressful."

句動詞とイディオム

"come across"

To find or meet something or someone by chance, or to give a certain impression to others.

"I came across this article while searching online — it's exactly what you need."

句動詞とイディオム

"break down"

For a machine to stop working, for negotiations to fail, or for someone to lose emotional control.

"The car broke down on the motorway, so we were late for the meeting."

句動詞とイディオム

"let someone down"

To disappoint someone by failing to do what they expected or needed from you.

"I promised I would be there, and I don't want to let you down."

句動詞とイディオム

"hit the nail on the head"

An idiom meaning to describe a situation exactly or to say something perfectly accurate.

"You hit the nail on the head — that is exactly what went wrong with the project."

句動詞とイディオム

"burn the midnight oil"

An idiom meaning to work or study late into the night in order to finish something.

"She's been burning the midnight oil all week to finish her dissertation."

句動詞とイディオム

"get the ball rolling"

An idiom meaning to start a process or activity, especially after a period of delay or inactivity.

"Let's get the ball rolling on the new marketing campaign — we've waited long enough."

スピーキングと流暢さ

"discourse markers"

Words and phrases that connect ideas and organise your speech, making it sound structured and natural to listeners.

"On the other hand", "having said that", "what's more", "to sum up" — these signal your meaning before you express it.

スピーキングと流暢さ

"filler phrases"

Short phrases used to keep a conversation going while you think, without going silent. Native speakers use these constantly.

"That's a good question...", "Let me think about that for a second...", "How can I put this..." keep the conversation flowing.

スピーキングと流暢さ

"hedging language"

Language that makes statements less absolute, expressing uncertainty or softening opinions to sound more polite and natural.

"I think", "as far as I know", "it seems to me", "you might want to consider" — used constantly in professional contexts.

スピーキングと流暢さ

"connected speech"

The way words link together, blend, and change sounds in natural spoken English — very different from how words sound individually.

"Do you want to?" sounds like "Dja wanna?" and "I don't know" sounds like "I dunno" in natural speech.

スピーキングと流暢さ

"intonation patterns"

The rise and fall of your voice, which carries meaning beyond the words. Wrong intonation can change meaning or make you sound rude.

A falling tone on "Really?" shows you believe someone; a rising tone shows surprise or disbelief.

スピーキングと流暢さ

"small talk strategies"

The art of light, friendly conversation that builds rapport. Knowing how to start, maintain, and close small talk is essential for social and professional settings.

"How's your week going?" "Not too bad, thanks — keeping busy! Do you have any plans for the weekend?"

スピーキングと流暢さ

"agreeing and disagreeing politely"

Language for expressing agreement or disagreement in a way that maintains good relationships and sounds professional.

"I see your point, but...", "I'd have to disagree there — I think...", "You're absolutely right about that."

スピーキングと流暢さ

"reformulation"

The skill of rephrasing what you have already said more clearly when you realise you have not been understood.

"What I mean is...", "Let me rephrase that...", "In other words..." — essential repair strategies for intermediate speakers.

リスニングと理解

"active listening"

Listening with full attention and purpose — focusing on key information, predicting what comes next, and checking your understanding as you go.

Before watching a TED Talk, note three questions you want answered. Check them off as you listen.

リスニングと理解

"extensive listening"

Listening to large amounts of English content that is slightly below your level for pleasure and fluency, without focusing on every word.

Watch an episode of a TV series you enjoy with English subtitles — understanding 80–90% is ideal.

リスニングと理解

"intensive listening"

Studying a short audio or video clip in detail: pausing, replaying, and analysing language, pronunciation, and meaning carefully.

Take a 2-minute news clip and transcribe every word. Then compare your transcript to the original text.

リスニングと理解

"inferring meaning from context"

Using surrounding information — vocabulary, tone, context, grammar — to deduce the meaning of words or sentences you do not know.

In "The CEO stepped down amid mounting pressure", "stepped down" can be inferred to mean resigned from context.

リスニングと理解

"accent familiarisation"

Deliberately exposing yourself to a wide range of English accents — American, British, Australian, Indian, Irish — to improve overall comprehension.

The BBC and CNN use different accents. Watching both regularly will improve your ability to understand diverse speakers.

リスニングと理解

"note-taking while listening"

Writing down key words, numbers, and ideas while listening to a lecture, meeting, or podcast to support memory and comprehension.

Use symbols (→ for leads to, ≠ for difference, ? for uncertain) to take notes faster without missing audio.

リスニングと理解

"bottom-up and top-down processing"

Bottom-up processing builds meaning from individual sounds and words; top-down uses prior knowledge and context. Both work together in real listening.

If you hear "election" you immediately activate top-down knowledge about politics, candidates, and voting.

リスニングと理解

"shadowing"

A technique where you listen to a recording and speak simultaneously, copying the speaker's rhythm, stress, and intonation to improve both listening and speaking.

Play a podcast at 90% speed and repeat each sentence as it plays — this trains your ear and mouth together.

学習戦略

"comprehensible input"

The theory that you acquire language by understanding messages slightly above your current level (i+1), not by drilling rules. Listening and reading are the main channels.

Choose YouTube videos or podcasts where you understand about 70–80% — challenging enough to grow, easy enough to follow.

学習戦略

"the intermediate plateau"

The frustrating stage where beginners become intermediate but progress slows because material feels too easy or too hard. The solution is deliberate practice at the right level.

If beginner series feel too easy but authentic podcasts feel impossible, you are on the plateau. Graded content is the bridge.

学習戦略

"output practice"

Actively producing language through speaking or writing, which forces your brain to process grammar and vocabulary more deeply than passive input alone.

Keep a daily journal in English: even five sentences about your day forces you to retrieve and use vocabulary actively.

学習戦略

"deliberate practice"

Focused, effortful work on specific weaknesses rather than just repeating what you already know. This is how intermediate learners continue improving.

If conditionals are a weakness, spend two weeks specifically reading, writing, and listening for conditional sentences.

学習戦略

"language exchange"

A partnership with a native English speaker learning your language, where you each help the other practice. Apps like Tandem and HelloTalk connect partners worldwide.

Spend 30 minutes speaking English, then 30 minutes speaking your partner's language — both of you benefit equally.

学習戦略

"chunking"

Learning language in meaningful groups (chunks) — phrases, fixed expressions, and collocations — rather than individual words. This is how native speakers store language.

Instead of learning "turn" and "around" separately, learn the chunk "turn around" with its meaning and common context.

学習戦略

"setting measurable goals"

Replacing vague goals ("improve my English") with specific, time-bound targets that you can actually measure and track.

"Learn 10 new collocations per week and use each one three times in writing" is measurable. "Be more fluent" is not.

学習戦略

"immersion at home"

Surrounding yourself with English throughout your daily life without travelling abroad, using technology to create an English-rich environment.

Change your phone language to English, listen to English radio while cooking, and read the news in English every morning.

よくある質問

B1–B2の中級英語とは実際にどういう意味ですか?

B1(中級)とB2(上中級)はヨーロッパ言語共通参照枠(CEFR)のレベルです。B1では旅行中のほとんどの状況に対処でき、経験や出来事を説明し、日常的な話題について話せます。B2では複雑なテキストの主要な考えを理解し、ある程度の流暢さで会話できます。ほとんどの学習者はC1に達する前に、このレベルで2〜4年を過ごします。

中級の壁をどうやって乗り越えればよいですか?

中級の壁は、初級段階の急速な進歩が遅くなることで起こります。解決策は3つあります。第一に、自分のレベルに合ったわかりやすいインプットを増やすこと。第二に、アウトプット(スピーキングとライティング)を定期的に練習すること。第三に、すでに知っていることを復習するのではなく、意図的な練習を通じて特定の弱点に集中することです。

中級レベルでは何語知っていればよいですか?

B1では通常2,000〜3,000の語族を知っており、B2では約4,000〜5,000です。最も頻度の高い3,000語を知っていれば、日常会話の約95%をカバーできます。まず高頻度語彙(Oxford 3000が良い参考書)に集中し、次に自分の生活や目標に関連するテーマ別クラスターに移りましょう。

中級レベルでは文法と語彙、どちらに多く集中すべきですか?

両方大切ですが、中級レベルではバランスが変わります。初心者は文法から最も恩恵を受けます。B1–B2では語彙が最大のボトルネックになります。このレベルのほとんどのコミュニケーション失敗は、語彙不足が原因であり、文法ミスではありません。とはいえ、混合条件文、話法転換、高度な法助動詞などの複雑な構造への集中的な取り組みも依然として有益です。

中級英語学習者が消費するのに最適なコンテンツは何ですか?

最良のコンテンツは、現在のレベルより少し上のものです。約70〜80%を努力なしに理解できるものが理想的です。人気の選択肢には、B1–B2レベルのグレーデッドリーダー、BBC Learning English、「6 Minute English」などのポッドキャスト、英語字幕付きテレビドラマ、発音が明瞭なYouTubeチャンネルなどがあります。重要な原則は量です。適切なレベルのインプットが多ければ多いほど、進歩は速くなります。

中級の壁を突破する最も速い方法は、わかりやすいインプットです。自分のレベルで毎日本物の英語を聞いて読むことが大切です。当サイトの動画ライブラリはB1–B2学習者のために設計されています。
