Part5で「However, the project was successful」「Therefore, we need to reconsider」のような接続表現が出ると、前後の文脈との論理的つながりで迷ったことはありませんか?
「Howeverって逆接だから、悪い話の後に来るんだよね?」「Thereforeの前には何が必要?」と悩んでしまう方も多いでしょう。
実は、これらは**意味の関連性(Semantic Coherence)**という概念に基づく表現で、論理的なつながりを明確に示します。
今回は、TOEIC Part5で最上級レベルの差がつく意味の関連性を、論理的つながりを作る5つのテクニックで完全にマスターしていきましょう。
意味の関連性の基本を理解しよう
まず、意味の関連性とは何かを整理しましょう。
意味の関連性とは、文と文、段落と段落の間に論理的で一貫した意味のつながりを作ることです。 日常生活で例えると、「雨が降った。だから試合が中止になった。」のような原因と結果の関係です。
基本的な論理関係:
- 因果関係:原因 → 結果
- 対比関係:AとBの違い・対立
- 追加関係:情報の付加・補強
- 時間関係:出来事の順序・時系列
- 条件関係:仮定と結論
重要なのは、読み手が論理の流れを自然に理解できることです。
Part5での出題パターン
意味の関連性は、Part5で年間約4-6問出題される最上級分野です。
主な出題パターンは以下の3つです。
パターン1:論理マーカーの選択
適切な論理マーカー(接続表現)を選ぶ問題です。
例題:
Sales have declined for three consecutive quarters. _____, management has decided to restructure the company.
(A) However
(B) Therefore
(C) Furthermore
(D) Meanwhile
正解は(B)です。 売上減少という原因に対する結果として「Therefore」が適切です。
パターン2:文脈との整合性
前後の文脈に論理的に合う表現の選択です。
パターン3:意味的統一性
文章全体の意味的統一性を保つ表現の判断です。

よくある間違いパターン
日本人学習者が特に間違えやすいポイントです。
間違い1:論理関係の逆転
❌ Sales increased significantly. However, we are pleased with the results. ✅ Sales increased significantly. Therefore, we are pleased with the results.
売上増加は好ましい結果なので逆接ではない。
間違い2:文脈との不整合
❌ The project failed completely. Furthermore, it exceeded all expectations. ✅ The project failed completely. However, we learned valuable lessons.
失敗に対してFurthermoreは論理的に不適切。
間違い3:不適切な強調
❌ The meeting was normal. Indeed, nothing special happened. ✅ The meeting was productive. Indeed, we resolved several important issues.
普通の出来事にIndeedは不自然。

理解度を確認してみましょう。
問題1:The new software has improved efficiency dramatically. _____, employee satisfaction has also increased.
(A) However
(B) Therefore
(C) Furthermore
(D) Nevertheless
どうでしょうか?
正解は(C)です!
効率改善という好ましい結果に、従業員満足度向上という追加の好ましい情報なので「Furthermore」が適切です。

(A) Therefore
(B) Furthermore
(C) Nevertheless
(D) Moreover
正解は(C)です!
