品詞判断
空所前後の構造（冠詞・前置詞・主語/動詞/目的語）と語尾シグナルで、必要な品詞を即断する。
Part 5の典型パターンで「形容詞/名詞/動詞/副詞」のどれが入るかを迷わず判定できるようにする。
⚠️ひっかけ注意 — よくある失点パターン
- 名詞の -al（approval/arrival/proposal）と形容詞の -al（official/financial）を区別。
- friendly, costly, timely など -ly でも形容詞の語に注意（副詞ではない）。
- 「to」の後は不定詞か前置詞かを熟語で判別（be committed to ~ing, look forward to ~ing）。
- 前置詞 to + 動名詞の他例：object to ~ing / be opposed to ~ing / dedicate A to ~ing。
- 名詞＋名詞（marketing strategy, safety standards など）も頻出。
