Grammar Rule in 30 Seconds
When counting how many times you have done something, always use the Present Perfect tense after the ordinal number.
- Use 'It is the first/second time' + Present Perfect. Example: 'It's the first time I've been here.'
- Never use the Simple Present after this phrase. Wrong: 'It's the first time I am here.'
- Use the Past Perfect if the main verb is in the past. Example: 'It was the first time I had seen it.'
Overview
It’s the first time I eat this と言いたかったのでしょう。残念ながら、あなたの英語の先生はそっと涙を流しているかもしれません。英語では、何かが何回起こったかを数えるとき、現在完了形（Present Perfect）を使います。これは、あなたの人生経験のスコアボードのようなものです。初めてのVlog投稿でも、ゲームの同じレベルで3回失敗したときでも、このパターンはあなたの強い味方です。過去の試行と、まさに「今」という瞬間を結びつけます。これまでの実績を自慢したり（あるいは不満を言ったり）する方法だと考えてください。インスタグラムで節目の出来事をシェアするときなど、思っている以上に頻繁に使われます。これを使わないと、古いSF映画のロボットのように聞こえてしまうかもしれません。パーティーで退屈なロボットになりたい人なんていませんよね。How This Grammar Works
It is the first time と言うとき、あなたはカウントするための舞台を整えています。英語の論理では、その経験が今も「真実」であるため、現在完了形が必要だと考えます。単に過去のことを話しているのではなく、現時点までの人生の合計回数について話しているのです。現在シンプル形（Simple Present）を使うと、永続的な習慣のように聞こえてしまい、混乱を招きます。過去シンプル形（Simple Past）を使うと、その出来事が今とは完全に切り離されているように聞こえます。have や has を使うことで、「カウント」がまだ継続していることを示します。スナップチャットの「ストリーク」のようなものです。以前に何が起こり、今何が起こっているかが重要なのです。序数（first, second, third）がトリガーであることを忘れないでください。それを口にした瞬間、脳は自動的に「現在完了形」のスイッチを入れるべきです。携帯が震えたときにチェックするような、反射に近いものです。
Formation Pattern
It is the... （または It's the...）。
first, second, third, tenth、あるいは only や last でもOK。
time という言葉を加える（これは必須です！）。
I, you, we, she, they など。
have または has。
seen, been, eaten, tried, clicked。
It is the [序数] time + [主語] + [have/has] + [過去分詞]
It's the first time + I + have + used + this app.
that を省略することができ（It's the first time *that* I've...）、ほとんどの人がそうします。その方が教科書っぽくなく、人間らしく聞こえます。ただし、 have は絶対に落とさないでください！ それはサンドイッチ全体をまとめる接着剤です。それがないと、サンドイッチはただの具材の山になってしまいます。
When To Use It
- 新しい経験:
It's the first time I've been to London.旅行Vlogのイントロに最適です。 - 繰り返される間違い:
It's the third time you've forgotten your password.自分の脳にイライラしたときに使いましょう。 - SNSのキャプション:
First time I've ever dyed my hair blue!投稿に重要性を加えます。 - 技術的な問題:
It's the second time the Wi-Fi has cut out during my Zoom call.リモートワークの世界では非常によくある光景です。 - ユニークな出来事:
It's the only time I've seen her cry.その瞬間がいかに珍しいかを強調します。
It's the second time I've managed a project like this と言えば、 I did this twice よりもずっとプロフェッショナルに聞こえます。自分の経験値（XP）を自覚していることを示せます。ゲームでレベルアップするようなものです。
Common Mistakes
It's the first time I am here. (✗) と言いますが、これはネイティブには非常に不自然に聞こえます。 It's the first time I've been here. (✓) と言うべきです。It's the first time I went there. (✗)。カジュアルな会話でこう言うアメリカ人もいますが、厳密には間違いで、少しだらしなく聞こえることがあります。he/she/it の場合は、 has の「s」を忘れないでください。 It's the first time she have called. (✗) ではなく、 she *has* called! (✓) です。It's the first time と言いたいときに It's the one time... と言わないように。数字と序数は別物です！It's the 5,000th time I've breathed today. (✗)。文法的には正しいですが、友達をなくすかもしれません。本当に重要だったり、注目に値することのために取っておきましょう。Contrast With Similar Patterns
I have been to Paris. （一般的な経験、特定の「回数」は言及しない）。It's the second time I've been to Paris. （順番に焦点を当てる）。This is the first time と That was the first time の違いはどうでしょうか？is を使うなら、現在完了形を使います： It's the first time I've seen this.was を使うなら、過去完了形にする必要があります： It was the first time I had seen this.is + have を使いましょう。3年前の日本旅行の話をしているなら、 was + had を使います。自転車のギアチェンジのようなものです。状況に合ったギアを使わないと、無駄に汗をかくだけです。Quick FAQ
これらの文章で ever を使えますか？
はい！ It's the first time I've ever eaten sushi と言うと、よりドラマチックでエキサイティングに聞こえます。
last でも使えますか？
もちろんです。 It's the last time I've ever helped him （将来の意向なら It's the last time I'm helping him と言いますが、完了形は最後の出来事を振り返る際に使えます）。
短縮形を使ってもいいですか？
はい、ぜひ使ってください！ I've, you've, he's, it's など。ネイティブはほとんど常に短縮形を使います。 It is the first time I have... と言うと、すごく長くて退屈なスピーチが始まるみたいに聞こえます。
正確な回数がわからない場合は？
many times や several times を使えますが、その場合はパターンが少し変わります： I've been here many times. 通常、 It's the many times I've been here. とは言いません。この特定の構造では、具体的な数字か only/last を使いましょう。
否定的なことにも使えますか？
はい。 It's the first time I haven't finished my homework. 少し硬く聞こえますが、文法的には正しいです！

In the phrase 'It's the first time,' the word 'first' (or second, third) usually receives the primary sentence stress to emphasize the order.
Contraction Reduction
The 've' in 'I've' or 's' in 'he's' is often very short and almost disappears in fast speech.

Story

文化メモ
British speakers are very strict about using the Present Perfect with 'first time'. Using the Simple Past ('It's the first time I went') sounds much more 'wrong' to a British ear than to some American ears.
While the Present Perfect is the standard, in very casual American speech, you might occasionally hear the Simple Past ('It's the first time I saw that'), though it is still technically incorrect in formal grammar.
Using 'This marks the first time...' is a common way to start press releases or formal announcements in English-speaking corporate environments.
The use of the perfect aspect with ordinals developed as English moved away from using the simple present for all 'state' descriptions in the Middle English period.

よくある質問 (8)
Yes, but only if you follow it with a noun or prepositional phrase (e.g., 'This is my first time in Japan'). If you want to use a verb, you must use the 'It's the first time I have...' structure.
In English, the Simple Present is for habits or general truths. A 'first time' is an experience that connects your past to now, which is the specific function of the Present Perfect.
No, 'that' is optional. 'It's the first time I've been here' and 'It's the first time that I've been here' are both correct, though the version without 'that' is more common in speech.
For the future, we usually use the Future Perfect: 'By next week, it will be the third time I have visited him.' However, this is quite advanced and less common.
Adding 'ever' is very common in spoken English because it adds emphasis to the newness of the experience.
Yes! 'This is the last time I have helped you!' (though 'This is the last time I am helping you' is also used for future intent).
Usually 'been' is used if you are currently at the place. 'Gone' is used if you are talking about the trip as a completed action.
The most common mistake is using the Simple Past: 'It's the first time I saw it.' Remember, if the first part is 'It IS', the second part must be 'have/has'.
