受動態と使役動詞を学ぼう！簡単で分かりやすい解説
1 / 5
受動態と使役動詞の基本をチェック
受動態は主語が「~される」立場を表す形で、基本は「S + be動詞 + 過去分詞」だったよね。でも高校では単純に訳すだけじゃダメ。感情や被害を表現する使い方がめちゃくちゃ重要になる。
使役動詞のmake、have、letは全部「~させる」って意味だけど、実はニュアンスが全然違う。makeは強制的に「やらせる」、haveは依頼して「してもらう」、letは許可して「させてあげる」って感じ。
テストでは特にこの3つの使い分けがよく出題される。例えば「My mom made me clean my room」は強制的に掃除させられたけど、「I had my brother carry my bag」は兄にお願いして運んでもらった、という違いがある。
💡 覚えるコツ: make=強制、have=依頼、let=許可って覚えておこう！
受動態のレベルアップ表現
感情を表す受動態では、byじゃなくて別の前置詞を使うことが多い。be interested in（~に興味がある）、be surprised at（~に驚く）、be satisfied with（~に満足する）みたいな感じ。これは熟語として丸暗記するしかない！
進行形の受動態は「be being + 過去分詞」で、今まさに動作が行われてる状態を表す。「The stadium is being built now」（スタジアムが建設中です）って感じ。
完了形の受動態は「have been + 過去分詞」で、もう終わった動作や継続してる状態を表現する。「My wallet has been stolen」（財布が盗まれちゃった）みたいに使う。
💡 テストのポイント: 進行形や完了形の受動態は長文でよく出るから、being や been を見逃さないように！
使役動詞と知覚動詞の受動態
これが一番ややこしいところ！makeの受動態では、消えていたtoが復活する。「S + make + O + do」が「O + be made + to do」になるんだ。「They were made to run」（走らされた）みたいに。
知覚動詞（see、hear、feel）も同じルール。「I saw him enter」が「He was seen to enter」になる。でも-ing形を使ってた場合は、受動態でもそのまま-ing形のまま。
letの受動態は特殊で、普通は使わない。代わりにbe allowed to do（~することを許可される）を使うのが一般的。「We were allowed to use the library」（図書館を使うことを許可された）って感じ。
💡 絶対覚えて: 受動態になると消えてたtoが復活する！これはテストで確実に狙われる。
have/getの特別な使い方
「have + O + 過去分詞」と「get + O + 過去分詞」は、文脈によって「依頼」か「被害」かの意味が変わる。これがめちゃくちゃ重要！
依頼の場合：「I had my hair cut」（髪を切ってもらった）、「I need to get my car repaired」（車を修理してもらう必要がある）みたいに、自分の意志でやってもらうとき。
被害の場合：「I had my wallet stolen」（財布を盗まれた）、「He got his leg broken」（脚を骨折した）みたいに、意図しない悪いことが起きたとき。
文脈で判断するしかないけど、主語の感情を考えるとわかりやすい。嬉しいことなら依頼、嫌なことなら被害って感じ。
💡 判断のコツ: 主語が喜んでそうなら依頼、困ってそうなら被害！
試験直前の最終チェック
使役動詞の受動態：make O do → be made to do（toを忘れるな！）
知覚動詞の受動態：see O do → be seen to do、see O doing → be seen doing
have/get + O + 過去分詞：「I had my hair cut」（依頼）vs「I had my wallet stolen」（被害）
進行形・完了形の受動態：「is being built」（建設中）、「has been stolen」（盗まれちゃった）
この4つのパターンをしっかり覚えておけば、長文読解でも英作文でも絶対に役立つ。特にtoの復活は100%テストに出るから、何度も練習して体で覚えよう！
💡 最後のアドバイス: 文法は理屈より慣れ！例文を声に出して読んで、自然に口から出るまで練習しよう。

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

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❗️❗️⚠️
