学べること

Awesome! In this chapter, you'll transform the way you speak Chinese. You'll move beyond simple sentences to build compelling arguments, explain reasons, and make suggestions with authentic Chinese logic. Ready to level up? First, you'll master '能' (néng). This powerful modal verb helps you determine if an action is possible given current circumstances, physical laws, or logistics. Imagine asking, 'Can I park here?' or 'Am I able to do this right now?' Next up is '吧' (ba). This small but mighty particle softens commands into friendly suggestions and turns statements into gentle assumptions. Think 'Let's go to the cafe, okay?' or 'I think he's here, right?' – making your conversations flow naturally. When logically connecting a fact to a conclusion, you'll use '既然...就...' (jìrán...jiù...), meaning 'Since... then...'. This allows you to articulate strong, logical links, moving from an established truth to a firm suggestion or consequence. To professionally explain the 'why' behind events, you'll learn '之所以...是因为...' (zhīsuǒyǐ...shì yīnwèi...). This pattern lets you first state the outcome, then clearly elaborate on the primary reason, giving your explanations a structured and impactful feel, like presenting an analysis. Finally, to spotlight specific details of a past action – *when*, *where*, or *how* it happened – you'll use '是...的' (shì...de). This adds emphasis, making your stories more vivid and ensuring your listener focuses on the exact information you want to highlight, for example, 'It was *I* who opened the door!' Picture yourself in a Chinese social setting, politely suggesting a new restaurant. Or needing to provide a solid, logical explanation for 'why you couldn't attend last week's meeting.' This chapter equips you to handle such situations with ease and confidence. By mastering these five golden patterns, you'll learn to forge logical links between ideas, interact subtly and respectfully, and confidently present your reasons and suggestions. It's time to transcend the intermediate level and speak with the persuasive logic of a truly fluent Chinese speaker!

How This Grammar Works

This chapter introduces five essential structures that will transform your Chinese grammar. First, 能 (néng) is a versatile modal verb indicating possibility or capability based on objective circumstances or physical laws. For example, 这里能停车吗？ (Can one park here?) asks if parking is feasible in this location.
Next, the particle 吧 (ba), placed at the end of a sentence, softens suggestions or adds a gentle, questioning tone. Think of it as saying okay? or right? as in 我们去吃饭吧。 (Let's go eat, okay?).
To express logical cause and effect, you'll master 既然...就... (jìrán...jiù...). This means 'Since...
then...' and clearly links an established fact to a logical consequence or suggestion. For instance, 既然你来了，就坐下吧。 (Since you've come, then sit down.) For explaining the 'why' behind an outcome, 之所以...是因为... (zhīsuǒyǐ...shì yīnwèi...) is indispensable.
This structure states the result first, then provides the primary reason: 他之所以成功，是因为他很努力。 (The reason why he succeeded is because he works very hard.) Finally, 是...的 (shì...de) is an emphasis structure used to highlight specific details (like *who*, *when*, *where*, or *how*) of a past action. For example, 我是在中国学的汉语。 (It was in China that I learned Chinese.)

Common Mistakes

  1. 1✗ Wrong: 我们去吃饭。 (Let's go eat.)
✓ Correct: 我们去吃饭吧。 (Let's go eat, okay?)
*Explanation:* While the first sentence is grammatically correct, adding 吧 softens the suggestion and makes it sound more polite and inviting, which is common in conversational Chinese.
  1. 1✗ Wrong: 他成功了因为他很努力。 (He succeeded because he worked hard.)
✓ Correct: 他之所以成功，是因为他很努力。 (The reason why he succeeded is because he worked very hard.)
*Explanation:* While 因为...所以... is also correct, 之所以...是因为... provides a more formal and structured explanation, emphasizing the specific reason for a previously stated outcome. It's often used when presenting an analysis or justification.
  1. 1✗ Wrong: 我在北京学汉语。 (I learn Chinese in Beijing.) - intended emphasis on Beijing for a past action.
✓ Correct: 我是在北京学的汉语。 (It was in Beijing that I learned Chinese.)
*Explanation:* To emphasize the location (*where*) of a *past* action, you need the 是...的 structure. Without it, the sentence sounds like a general statement of fact or a present action.

Quick FAQ

Q

What's the main difference between 能 (néng) and 可以 (kěyǐ) in Chinese grammar B1?

能 often refers to objective possibility or capability based on circumstances or physical conditions, while 可以 often implies permission or subjective ability.

Q

Can 吧 (ba) be used in formal writing or speeches?

Generally, 吧 is more common in spoken Chinese and informal writing. In very formal contexts, it might be omitted or replaced with more formal phrasing.

Q

How does 之所以...是因为... differ from a simple 因为...所以... structure in Chinese grammar?

之所以...是因为... states the outcome first, then the reason, emphasizing the reason for a *known result*. 因为...所以... states the cause first, then the effect, focusing on the logical flow from cause to outcome.

Q

Is the 是...的 (shì...de) structure only for past events in B1 Chinese?

Yes, the 是...的 structure for emphasis is typically used for *past* actions or events to highlight specific details like *when*, *where*, *how*, or *who* performed the action.

Cultural Context

These Chinese grammar patterns are deeply embedded in how native speakers communicate, reflecting a culture that often values politeness, indirectness, and clear, structured reasoning. The use of 吧 exemplifies the desire to soften requests and maintain harmony. Structures like 既然...就... and 之所以...是因为... allow for precise and logical articulation of ideas, crucial in both academic and professional settings.
The 是...的 construction helps listeners focus on key information, ensuring clarity in storytelling or explanations. Mastering these patterns allows you to speak not just correctly, but also culturally appropriately.

ヒントとコツ (4)

💡

迷ったら「吧」を付けてみて

自分の言い方がきつすぎないか心配な時は、「吧」を付けるだけでぐっとフレンドリーになるよ。 «我们走吧。»
frontend.learn_grammar.from_rule: `吧` (ba) を使った提案
🎯

「是」を省略してネイティブっぽく！

日常会話やチャットでは、8割くらいの確率で「 client 」を省略します。「的」さえ最後に残っていれば、文法は完璧ですよ！ «你怎么来的？»
frontend.learn_grammar.from_rule: 是...的（shì...de）で詳細を強調する
⚠️

「所以」は使っちゃダメ！

«既然» で始めた文の後半に «所以» (だから) を使うのはNG。必ず «就» を使って、翻訳機っぽさを卒業しよう。 «既然下雨了，就不出去了。»
frontend.learn_grammar.from_rule: 中国語の論理：『〜からには…』（既然...就...）
💡

もっとフォーマルにするなら

レポートやスピーチでは「是因为」を「是由于」 (shì yóuyú) に変えると、より知的でアカデミックな響きになりますよ。 «他之所以成功是由于坚持不懈。»
frontend.learn_grammar.from_rule: 「なぜなら」を強調する：理由の説明 (之所以...是因为...)

重要な語彙 (6)

建议(jiànyì) suggestion / to suggest 决定(juédìng) to decide 停车场(tíngchēchǎng) parking lot 迟到(chídào) to be late 休息(xiūxi) to rest 清楚(qīngchu) clear / clearly

Review Summary

  • [Statement] + 吧 (ba)
  • 是 (shì) + [Detail] + Verb + 的 (de)
  • 既然 (jìrán) + Fact, 就 (jiù) + Result
  • 之所以 (zhīsuǒyǐ) + Effect, 是因为 (shì yīnwèi) + Cause
  • 能 (néng) + Verb

よくある間違い

The 'shì...de' structure is only for emphasizing details of past events that have already occurred. It cannot be used for future intentions.

Wrong: 我是明天去的 (Wǒ shì míngtiān qù de)
正解: 我明天去 (Wǒ míngtiān qù)

In the 'jìrán...jiù...' pattern, the word 'jiù' is almost always required in the second clause to create the logical link.

Wrong: 既然下雨，我不去 (Jìrán xiàyǔ, wǒ bù qù)
正解: 既然下雨，我就不去 (Jìrán xiàyǔ, wǒ jiù bù qù)

Use 'néng' for situational possibility (having time). 'Huì' is for learned skills or future probability.

Wrong: 我会去，因为我有时间 (Wǒ huì qù, yīnwèi wǒ yǒu shíjiān)
正解: 我能去，因为我有时间 (Wǒ néng qù, yīnwèi wǒ yǒu shíjiān)

正しい否定の形を選んで空欄を埋めてください。

我___坐地铁来的，我开车来的。

✓ Correct! ✗ Not quite. Correct answer: 不是
「是...的」構文を否定するときは、不を使わずに「不是（bú shì）」を使うのが鉄則です。

frontend.learn_grammar.from_rule: 是...的（shì...de）で詳細を強調する

正しい助動詞を選んで空欄を埋めましょう。

My phone is dead, so I ___ call you. ({我手机没电了，所以我___给你打电话|Wǒ shǒujī méidiàn le, suǒyǐ wǒ ___ gěi nǐ dǎ diànhuà}.)

✓ Correct! ✗ Not quite. Correct answer: 不能 (bùnéng)
これは、携帯の充電がないという状況が行動を妨げているので、「不能」が正解です。「不会」は、電話のかけ方を知らない、というスキルがないことを意味します。

frontend.learn_grammar.from_rule: 能 (néng) で可能性を表現する

文の文脈における間違いを見つけましょう。

Find and fix the mistake:

文脈：誰かが水泳のスキルを習得したかどうかを尋ねています。 文：{你能游泳吗|Nǐ néng yóuyǒng ma}?

✓ Correct! ✗ Not quite. Correct answer: 「能」を「会（{会|huì}）」に置き換える
水泳のように習得したスキルについて尋ねる場合、「会」が正しい動詞です。「能」は、今、身体的に泳げるか（例：怪我をしていないか）を尋ねる時に使います。

frontend.learn_grammar.from_rule: 能 (néng) で可能性を表現する

「辛いものが食べられますか？」（耐性がありますか？）という質問に最適な文を選びましょう。

最も自然な翻訳を選んでください。

✓ Correct! ✗ Not quite. Correct answer: {你能吃辣吗|Nǐ néng chī là ma}?
辛いものを食べることは、運転のように習得するスキルではなく、身体的に辛さに耐えられるか（許容量）を指します。そのため、「能」が最適です。

frontend.learn_grammar.from_rule: 能 (néng) で可能性を表現する

文法的に正しい「昨日、彼に会った」という文を選んでください。

Choose the right way to say 'I saw him yesterday'.

✓ Correct! ✗ Not quite. Correct answer: 我是昨天看见他的。
目的語が「他（彼）」のような代名詞の場合、必ず「的」の前に置かなければなりません。

Score: /6

よくある質問 (6)

日本語の「〜しよう」「〜だよね」に近いよ。文の雰囲気を柔らかくするツールだと思ってね。 «走吧。»
すごく簡単！文の最後に置くだけだよ。 «我们走吧。»
文章の中の「ハイライト」のような役割です。起きた出来事そのものより、いつ、どこで、どうやって、誰と、といった「詳細」に注目を集めます。 «我是昨天来的。»
いいえ、使えません。この構文は「すでに起きたこと」の詳細を語るためのものなので、過去の事実に限定されます。 «我是去年买的。»
はい！ {你既然...|nǐ jìrán...} でも {既然你...|jìrán nǐ...} でもOKです。会話では主語を先にする方が少し自然に聞こえますよ。
もちろんです。スピーチや作文などで、既存の事実から論理的な主張を導き出す時に非常によく使われます。
