IELTSスピーキングの文法:Band 7+を獲得するための構文
Band 7では「多様な複雑な構文」で「頻繁に正確な文」を作ることが求められます。文法規則を暗記することではなく、多様な文法を自然に使いこなすことが大切です。
試験官が聞きたい構文
1. 仮定法(Conditional Sentences)
- Second conditional(仮定法過去): "If I had more time, I would travel more often."
- Third conditional(仮定法過去完了): "If I had studied harder, I might have gotten a scholarship."
- Mixed conditional(混合仮定法): "If I had taken that job, I would be living in London now."
仮定法はPart 3の「もし〜だったら」という質問で特に役立ちます。日本語にも仮定表現はありますが、英語の仮定法は時制の使い分けが重要です。
2. 受動態(Passive Voice)
- "The city has been transformed by rapid development."
- "Children should be encouraged to read from an early age."
- "It could be argued that technology has made life easier."
受動態は特にPart 3で社会的な話題を議論する際に便利です。行為者ではなく結果に焦点を当てたいときに使いましょう。
3. 関係詞節(Relative Clauses)
- "The teacher who had the biggest impact on me was my high school English teacher."
- "My hometown, which is a small coastal city, has changed dramatically."
- "The reason why I chose this career is that I've always been fascinated by technology."
関係詞節を使うと、一つの文に多くの情報を自然に盛り込めます。
4. 完了形(Perfect Tenses)
- Present perfect: "I've been studying English for about 10 years now."
- Present perfect continuous: "I've been working on improving my pronunciation lately."
- Past perfect: "By the time I arrived, the meeting had already started."
日本語には英語のような完了形がないため、日本人受験者は特にこれらの時制の使い分けを練習する必要があります。
5. 分裂文(Cleft Sentences — 強調構文)
- "What I really enjoy about my job is the variety."
- "It was my mother who inspired me to become a teacher."
- "What concerns me most is the impact on the environment."
分裂文を使うと、特定のポイントを効果的に強調できます。これはBand 7+の特徴的な構文です。
6. 比較構文
- "The more I practice, the more confident I become."
- "It's far more effective than traditional methods."
- "This is by far the most challenging aspect of the test."
よくある文法エラー
| エラーの種類 | 間違い | 正しい |
|---|---|---|
| 主語と動詞の一致 | "People is important" | "People are important" |
| 冠詞 | "I go to university"(特定の大学について) | "I go to the university near my house" |
| 時制 | "Yesterday I go to the shop" | "Yesterday I went to the shop" |
| 前置詞 | "Depend of" | "Depend on" |
| 可算/不可算 | "Many informations" | "A lot of information" |
| 現在完了 | "I am living here since 2020" | "I have been living here since 2020" |
日本人受験者が特に注意すべき文法ポイント
- 冠詞(a/an/the): 日本語には冠詞がないため、最もミスが多い項目です。特に"the"の使い方に注意しましょう。
- 単数/複数: "information"(不可算)、"advice"(不可算)に"-s"をつけないでください。
- 前置詞: "interested in"(〜に興味がある)、"good at"(〜が得意)など、動詞・形容詞とセットで覚えましょう。
- 主語の省略をしない: 日本語では主語を省略しますが、英語では必ず主語が必要です。
練習問題
Part 3の質問に答えて、最低3つの異なる複雑な構文を使ってみましょう:
"How has technology changed the way people work?"
回答例(Band 7): "Technology has fundamentally transformed the workplace(現在完了+受動態). What I find most remarkable is that people can now work from virtually anywhere(分裂文). If this trend continues, I believe traditional offices might become obsolete(第一条件文+助動詞)."
