分詞の基本的な使い方：簡単なガイド
1 / 6
分詞の基本ルール
分詞は動詞を形容詞や副詞みたいに使う便利な技だよ。現在分詞（-ing形）と過去分詞（p.p.）の2種類があって、どっちを使うかは能動か受動かで決まる。
**現在分詞（-ing形）**は「〜している」という意味で、修飾する名詞が「〜する」側のとき使う。例えば、sleeping baby（眠っている赤ちゃん）は、赤ちゃんが「眠る」側だから現在分詞だね。
**過去分詞（p.p.）**は「〜される・された」という意味で、修飾する名詞が「〜される」側のとき使う。broken window（割られた窓）は、窓が「割られる」側だから過去分詞を選ぶんだ。
覚え方のコツ: 修飾される名詞を主語、分詞を動詞だと思って「SがVする」なら-ing、「SがVされる」ならp.p.！
名詞を修飾する分詞（形容詞的用法）
分詞で名詞を詳しく説明するとき、置く場所が超重要だよ。1語なら前、2語以上なら後ろに置くって覚えておこう。
前から修飾するのは分詞が1語だけのとき。an exciting game（わくわくさせる試合）みたいに、名詞の直前に置く。感情を表す動詞は要注意で、excited people（興奮した人々）のように、人が主語なら過去分詞になることが多いんだ。
後ろから修飾するのは分詞が他の語句を伴って長くなるとき。The boy running over there（あそこを走っている少年）みたいに、名詞の後ろに分詞句全体を置く。
テストのポイント: 感情動詞（excite, surprise, interest等）で人が主語なら過去分詞、モノ・コトが主語なら現在分詞を選ぼう！
分詞構文の作り方と意味
分詞構文は接続詞+主語+動詞の文を分詞を使って短くする技だよ。作り方は簡単で、①接続詞を消す ②主語を消す ③動詞を-ing形にするだけ。
分詞構文が表す意味は文脈で判断する。時（Walking along the street, I met an old friend. 道を歩いているとき、旧友に会った）、理由（Feeling sick, I went to bed early. 気分が悪かったので、早く寝た）、付帯状況（〜しながら）などがある。
受動態の分詞構文では、being + p.p.になるけど、beingは省略されることが多い。Seen from the plane, the island looks beautiful.（飛行機から見ると、島は美しく見える）みたいに、過去分詞から始まる形になるよ。
重要な注意点: 分詞構文の意味上の主語は、必ず主節の主語と同じでなければいけない！
実践問題と解き方
例文で確認してみよう。The girl a book by the window is my sister.という問題では、まず修飾される名詞「girl」を確認する。
次に、girlとreadの関係を考える。少女は本を「読む」側だから能動関係。だから現在分詞のreadingを選んで、The girl reading a book by the window is my sister.（窓のそばで本を読んでいる少女は私の妹です）が正解だ。
分詞構文の問題 by the news, he couldn't say anything.では、主節の主語「he」に注目。彼はニュースに「衝撃を受けた」側（受動）だから、過去分詞のShockedを選ぶ。
解答のコツ: 修飾される名詞（または主節の主語）が「〜する」側なら現在分詞、「〜される」側なら過去分詞を選べば間違いなし！
テスト対策と重要ポイント
感情動詞（excite, surprise, interest等）の使い分けが頻出だよ。人を主語にするときは感情を「与えられる」ので過去分詞（I am interested in history.）、モノ・コトを主語にするときは感情を「与える」ので現在分詞（This book is interesting.）を使う。
分詞構文では、意味上の主語が主節の主語と一致するか必ずチェック！Walking down the street, a dog barked at me.みたいに、私が歩いているのに犬が主語になってる文は間違いだからね。
否定形では、分詞の直前にNotやNeverを置く。Not knowing what to do, I asked for help.（何をすべきかわからなかったので、助けを求めた）みたいに使うよ。
最終チェック: とにかく修飾する名詞との関係（能動か受動か）を常に意識すること！これをマスターすれば分詞は得意科目になるはず。

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️
