英語の前置詞って難しそう?実は、3つの基本(in, on, at)をイメージで覚えるだけで、テストでもバッチリ使えるようになるんだ。「点→面→空間」の順番で理解すれば、もう迷わない!







前置詞は名詞の前に置く小さな言葉だけど、文の意味を決める超重要な役割を持ってる。「いつ」「どこで」を正確に伝えるために絶対に必要なんだ。
前置詞は必ず名詞とセットで使う。「in the park」「at seven o'clock」みたいに、前置詞の後には必ず名詞か代名詞が来るよ。
基本の3つ「in」「on」「at」は、「広い→せまい」の順番で覚えよう。inが一番広くて、atが一番せまい「点」のイメージだ。
覚えるコツ: 単語だけじゃなくて「at the station」みたいに、うしろの名詞とセットで覚えると効果的!

場所を表すときは、その場所を「点」「面」「空間」のどれで見るかが大事。これができれば、もうテストも怖くない!
atは点のイメージ。地図上の一点や特定の場所を指すときに使う。「at the station」「at home」みたいに、その場所を待ち合わせ地点として見てる感じだね。
onは面に接しているイメージ。テーブルの上や壁など、何かの表面にくっついている状態を表す。「on the desk」「on the wall」って感じ。
inは空間の中のイメージ。建物の中や箱の中、都市や国など、立体的な空間や広い範囲を表すときに使うよ。
テスト対策: 乗り物も要注意!電車・バスは「on」、車・タクシーは「in」を使う。

時を表すときも、場所と同じように「点の時間」「特定の日」「長い期間」かで使い分ける。カレンダーをイメージすると分かりやすいよ。
atは時刻など、一点の時間。「at 7:30」「at noon」のように、具体的な時刻を指すときに使う。時間のピンポイントって感じだね。
onは特定の日や曜日。カレンダーの「1マス」に当たる部分で、「on Sunday」「on May 5th」みたいに使う。
inは月・季節・年など、長い期間。カレンダーの「1枚」や「全部」に当たる感じで、「in summer」「in 2024」って使うよ。
例外注意: 「朝・昼・夕方」は「in」だけど、「夜」だけは「at night」!これは覚えるしかない。

実際の文でどう使うかを練習してみよう。パターンを覚えれば、応用問題もスラスラ解けるようになる!
場所の例文:「There is a picture on the wall.」壁の表面にかかっているから「on」。「I play soccer in the park.」公園という空間の中だから「in」だね。
時の例文:「My school starts at 8:30.」時刻だから「at」。「We have a test on Friday.」特定の曜日だから「on」。「My brother was born in 2010.」年だから「in」。
覚え方のコツは、前置詞と名詞をセットで覚えること。「at the library」「on Monday」「in Japan」みたいに、まとまりで頭に入れよう。
テストの裏技: 迷ったときは「点→面→空間」「短い時間→1日→長い期間」の順番で考えてみて!

テストでよく出る引っかけポイントを知っておくと、確実に点数アップできる。これらを覚えておけば、もう迷わないよ!
時間表現の例外:「in the morning/afternoon/evening」だけど「at night」。夜だけ特別なので、セットで覚えておこう。
乗り物の使い分け:電車やバスのように中で動ける広い乗り物は「on」、車やタクシーのように座るだけのせまい乗り物は「in」を使う。
曜日・日付と月・年の区別:カレンダーの1マスに当たる「on Monday」「on the 10th」、カレンダー1枚分の「in May」「in 2024」って覚えよう。
最終チェック: 前置詞は単語だけじゃなく、うしろの名詞とのコンビネーションが大事。パターンで覚えるのが成功の秘訣!

基本のイメージさえつかめば、応用問題も自信を持って解けるようになる。君なら絶対にできる!
at: 「点」のイメージ。特定の場所(at the library)、特定の時刻(at 5 p.m.)で使う。
on: 「面」のイメージ。表面(on the table)、特定の日付や曜日(on Friday)で使う。
in: 「空間・中」のイメージ。広い場所(in Japan)、月や年などの長い期間(in summer)で使う。
チェックリスト:at nightとin the morningの違い、乗り物のonとinの使い分け、場所と時のイメージのピラミッドを頭に入れたかな?
応援メッセージ: この基本ルールを使いこなせれば、英語の表現力がグンとアップする。練習すれば必ずマスターできるよ!

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.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
