Day 4：形容詞が正解になるパターン ― 名詞の前と補語の位置を攻略する

なぜやるか

Day 3で名詞が正解になるパターンを学びました。名詞は品詞問題の約4割を占める最頻出パターンでした。

今日は形容詞です。

形容詞が正解になる割合は約3割。名詞と合わせると、品詞問題の約7割をカバーできます。

形容詞が入る位置は、名詞に比べるとパターンが少なく覚えやすいです。今日マスターすれば、品詞問題の大半が解けるようになります。

本編

形容詞が入る3つのパターン

パターン①：冠詞 + ____ + 名詞（名詞を前から修飾）

The company announced an _____ change in its pricing policy.

冠詞と名詞の間。名詞を修飾するのは形容詞。

このパターンが最も多い。a/an/the の後ろに空欄があったら、まず形容詞を疑う。

パターン②：be動詞 + ____（補語の位置）

The conference room is _____ for meetings on Friday afternoons.

be動詞の後ろ。主語とイコールになる補語（C）の位置。ここに入るのは形容詞。

be動詞以外にも、seem（〜に見える）、remain（〜のままだ）、become（〜になる）の後ろも補語 = 形容詞。

パターン③：make / find / keep + O + ____（SVOC構文の補語）

The new software makes data analysis _____.

make O C = 「OをCにする」。O = C の関係が成り立つので、Cは形容詞。

find O C（OをCだと思う）、keep O C（OをCに保つ）も同じパターン。

紛らわしいケース：名詞？ 形容詞？

空欄の前が冠詞で、後ろが名詞のとき：

a _____ report

ここは形容詞が入る。でも、名詞 + 名詞のパターン（management team のように）もある。

見分け方： 選択肢に名詞と形容詞の両方があるとき、後ろの名詞との意味の関係で判断する。

• a comprehensive report（包括的な報告書）→ 形容詞 ✓
• a management report（経営報告書）→ 名詞 + 名詞 ✓

どちらも文法的に正しい。選択肢を見て、形容詞語尾（-ive, -ble, -ful, -ous 等）があればそちらを選ぶ。
