さて、今回から所有格の練習に入ります。
いつも通り、基本の例文を確認することから始めます！
🔶 関係代名詞・所有格（whose）
基本例文
🔹 形の確認
先行詞 + whose + 名詞 + 動詞 〜
👉 whose は 「〜の」
👉 人・物の両方に使える
🔷 基本例文 ①〜③（先行詞が人）
① I know a boy whose father is a doctor.
（私は父親が医者の男の子を知っています）
② She is the woman whose bag was stolen.
（彼女はバッグを盗まれた女性です）
③ This is the student whose English is very good.
（この生徒は英語がとても上手です）
🔷 基本例文 ④〜⑥（先行詞が物）
④ I have a house whose roof is red.
（私は屋根が赤い家を持っています）
⑤ This is a book whose cover is beautiful.
（これは表紙が美しい本です）
⑥ We visited a park whose trees are very old.
（私たちは木がとても古い公園を訪れました）
🔶 ポイント
✔ whose の後ろは必ず「無冠詞の名詞」
✔ 人にも物にも whose を使い、thatも使えない
ここから３つのステップを踏んで練習していきます。
🔶 ステップ①：2文 → 1文
（関係代名詞・所有格：whose）
▶ 手順
- 共通の名詞（先行詞）を見つける
- 後ろの文の 所有格（his / her / its / their）＋名詞 に注目
- whose＋名詞 に置き換えて1文にする
① I know a girl. Her brother is a doctor.
- her brother → whose brother
- 先行詞：a girl（人）
→ I know a girl whose brother is a doctor.
② He is the man. His car was stolen.
- his car → whose car
- 受け身でも形は同じ
→ He is the man whose car was stolen.
③ I bought a house. Its roof is red.
- its roof → whose roof
- 物でも whose を使う（重要）
→ I bought a house whose roof is red.
④ They are students. Their teacher is very kind.
- their teacher → whose teacher
- 先行詞が複数でも whose は変わらない
→ They are students whose teacher is very kind.
⑤ We visited a park. Its trees are very old.
- its trees → whose trees
- trees が複数でもOK
→ We visited a park whose trees are very old.
では次のステップに進みます。
👉 前回練習した主格（who / which / that）か所有格（whose）のどちらが空欄に適しているか選んで入れてみましょう！
🔶 ステップ②：穴埋め問題
関係代名詞（主格 or 所有格）
（ ）に who / which / that / whose のいずれかを入れましょう。
※文法的に複数正解がある場合があります。
① I know a man ( ) lives next door.
② She is the woman ( ) bag was stolen.
③ This is the book ( ) changed my life.
④ I have a friend ( ) father is a teacher.
⑤ We visited a park ( ) has many old trees.
⑥ He is the student ( ) English is very good.
⑦ I saw a dog ( ) was very big.
⑧ This is the house ( ) roof is red.
⑨ She met a girl ( ) helped her yesterday.
⑩ I bought a bag ( ) color I like very much.
解答と解説：関係代名詞（主格 / 所有格）
① I know a man who / that lives next door.
- （ ）の直後：lives（動詞）
- → 主格
- 先行詞：man（人）→ who / that
② She is the woman whose bag was stolen.
- （ ）の直後：bag（名詞）
- → 所有格
- 「彼女のバッグ」＝ whose bag
③ This is the book which / that changed my life.
- changed（動詞）が続く
- → 主格
- book（物）→ which / that
④ I have a friend whose father is a teacher.
- father（名詞）が続く
- → 所有格
- friend（人）→ whose father
⑤ We visited a park which / that has many old trees.
- has（動詞）が続く
- → 主格
- park（物）→ which / that
⑥ He is the student whose English is very good.
- English（名詞）が続く
- → 所有格
- 「彼の英語」→ whose English
⑦ I saw a dog which / that was very big.
- was（動詞）が続く
- → 主格
- dog（動物）→ which / that
⑧ This is the house whose roof is red.
- roof（名詞）が続く
- → 所有格
- its roof → whose roof
⑨ She met a girl who / that helped her yesterday.
- helped（動詞）が続く
- → 主格
- girl（人）→ who / that
⑩ I bought a bag whose color I like very much.
- color（名詞）が続く
- → 所有格
- 「そのバッグの色」＝ whose color
※ 学習段階として非常に良い例文
🔶 判断の最重要ルール（板書用まとめ）
👉 関係代名詞の直後を見る！
| 直後 | 使う関係代名詞 |
|---|---|
| 動詞 | 主格（who / which / that） |
| 名詞 | 所有格（whose） |
✔ 人・物どちらも whose
✔ 主格は省略不可／所有格も省略不可
はい、ここまで問題なくできましたか？
