It is precisely because parents think of their children's future that they dare to say harsh things.
📖 解説とニュアンス
### Correct Answer **1. ばこそ (ba koso)** * **Meaning/Usage**: This grammar point means "precisely because..." or "for the very reason that..." It strongly emphasizes that the stated reason is the one and only special reason for a particular result. It is often used when the reason stems from a deep emotion like love, consideration, or goodwill. The resulting action can sometimes seem surprising or contradictory. It is a formal and literary expression. * **Structure**: Verb conditional 'ba' form + こそ. * **Why it's correct here**: The action of "parents saying harsh things" might seem to contradict the idea of love. The phrase 「思えばこそ」 (omoeba koso) perfectly expresses the strong emphasis that "thinking about the child's future" is the sole, true reason for this seemingly harsh action. It is the most suitable choice for this context. ### Incorrect Choices **2. からこそ (kara koso)** * **Meaning/Usage**: Similar to `〜ばこそ`, this also emphasizes a reason, but it is more general and does not carry the same strong nuance of a unique or special emotional motivation. * **Why it's incorrect here**: Grammatically, 「思うからこそ」 (omou kara koso) is possible and the sentence would make sense. However, `〜ばこそ` is the better choice because it more effectively captures the strong, somewhat paradoxical sentiment of "taking on a difficult role precisely because of deep love." At the JLPT N1 level, distinguishing between such subtle nuances is key. `〜ばこそ` is more literary and better expresses the special nature of the parents' feelings. **3. ばかりに (bakari ni)** * **Meaning/Usage**: This pattern means "simply because of X, an unexpected negative result Y happened." It is often used to express regret, blame, or disappointment about the outcome. * **Structure**: Primarily Verb (past tense/plain form) + ばかりに. * **Why it's incorrect here**: The latter half of the sentence, "they say harsh things on purpose," describes a deliberate action, not a negative or failed outcome. The sentence as a whole has no nuance of regret or blame; in fact, it justifies the action. Therefore, `ばかりに`, which implies a bad result caused by something, is completely contradictory in meaning. **4. だけに (dake ni)** * **Meaning/Usage**: This means "precisely because A, it is all the more B" or "as expected from A, B." It indicates that there is a natural, expected, or logical relationship between the reason and the result, and the result is often intensified because of that reason. * **Structure**: Noun/Verb/Adjective (plain form) + だけに. * **Why it's incorrect here**: Saying harsh things is not a natural or expected consequence of thinking about a child's future. A more common expectation would be to be kind. This sentence explains the *special reason* for an action that goes against general expectations. It does not fit the logical relationship of "because of A, it is natural that B," which `だけに` implies. Therefore, it is inappropriate for this context.
### 正解 **1. ばこそ** * **意味・用法**: 「〜という特別な理由があるからこそ(他の理由ではない)」という意味で、ある事柄の唯一の理由を強く強調する表現です。特に、その理由が深い愛情、思いやり、善意といった特別な心情から来ている場合に多く使われます。結果として起こる事柄は、一見すると意外であったり、矛盾しているように見えたりすることもあります。文語的で改まった言い方です。 * **接続**: 動詞の仮定形(ば形) + こそ * **この文での適切性**: 「親が子供に厳しいことを言う」という行動は、一見すると愛情に反するように見えます。しかし、「子供の将来を思う」という深い愛情こそが、その行動の唯一の、そして真の理由なのだ、という強い強調のニュアンスを「思えばこそ」は完璧に表現します。この文脈に最も適した選択肢です。 ### 不正解の選択肢 **2. からこそ** * **意味・用法**: 「〜ばこそ」と同様に理由を強調しますが、より一般的に使われ、「ばこそ」ほど唯一性や特別な心情を強調するニュアンスは強くありません。 * **なぜこの文脈では不適切か**: 文法的には「思うからこそ」も可能で、意味も通じます。しかし、この文が持つ「深い愛情があるからこそ、あえて辛い役割を担う」という、やや逆説的で強い心情を表現するには、「ばこそ」の方がより文学的で、強調の度合いも高く、最適です。JLPT N1では、文法的な正しさだけでなく、このようなニュアンスの差が問われます。 **3. ばかりに** * **意味・用法**: 「〜という、たった一つの原因のせいで、予期せぬ悪い結果になった」という意味で使われます。話者の後悔や非難、残念な気持ちを表すことが多いです。 * **接続**: 主に動詞のタ形・普通形 + ばかりに * **なぜこの文脈では不適切か**: この文の後半「あえて厳しいことを言うのだ」は、悪い結果や失敗ではなく、親の意図的な行動です。文全体に後悔や非難のニュアンスは全くなく、むしろその行動を正当化する文脈です。したがって、「〜が原因で悪い結果になった」という意味の「ばかりに」は、意味的に完全に矛盾します。 **4. だけに** * **意味・用法**: 「〜という理由があるから、なおさら〜だ」「〜なので、当然〜だ」という意味で、理由と結果の間に、当然の、あるいは予測される関係があることを示します。その理由によって、結果の程度がより一層強まることを表します。 * **接続**: 名詞・動詞・形容詞の普通形 + だけに * **なぜこの文脈では不適切か**: 「子供の将来を思う」からといって、「厳しいことを言う」のが当然の帰結というわけではありません。むしろ、愛情があるなら優しくするというのが一般的な予測です。この文は、その予測に反する行動の「特別な理由」を述べています。「だけに」が示すような「Aだから当然Bだ」という論理関係には当てはまらないため、不適切です。
