英検準2級プラスの英作文は、「身近な社会的な話題について、情報や自身の考えなどを多様な語句を用いながら50～60語の英文で書き、理由を2つ述べる」という形式です。準2級に比べ、やや複雑なトピックと豊富な語彙力が求められます。ここでは、時間配分から構成テンプレート、文法チェックリスト、さらには頻出テーマの予想問題と解答例（Yes/No 両方）を大公開します！

1. 時間配分：15～20分でスラスラ書くための秘訣

英検準2級プラスのライティングにかけられる時間は限られています。約15～20分で次のステップを踏むと、本番でも落ち着いて答案を仕上げられます。

ステップ	目安時間	具体的行動
1. QUESTION把握	1～2分	– 質問文をじっくり読む。- YesかNoか、あるいは賛成か反対かを素早く決める。
2. 理由のアイデア出し	2～3分	– 2つの理由を考え、ササッとメモ。- 具体例やキーワード（英/日どちらでもOK）を忘れずに書く。
3. 枠組み・文構成	2～3分	– 「導入 → 理由1 → 理由2 → 結論」の順番を決定。- 接続詞や使えそうなフレーズをメモ。
4. 英文を書く	6～8分	– テンプレートを参考に一気に書き上げる。- シンプルかつ明確に、50～60語を意識する。
5. チェック・語数調整	2～4分	– 文法・スペル・冠詞などを見直す。- 50～60語を確保しつつ冗長表現がないか再確認。

ポイント

• 「構成を考える時間」を削りすぎると、書いている途中で迷ってしまい、文が散漫になりがち。
• 最初の数分で意見＆理由のざっくりメモをとるだけで、執筆が数倍はかどります。

2. お決まりの流れ：導入 → 理由1 → 理由2 → 結論

2-1. 全体構成を一瞬で作れるテンプレート

英作文では、「意見 → 理由1（+補足） → 理由2（+補足） → 結論」のシンプル構成が鉄板です。具体的には下記のような流れをイメージしましょう。

1. 導入（主張）：
   • I (agree / disagree) with the idea that ～.
   • I think ～. / I believe ～.
   • …などで端的に意見を示す。
2. 理由1：
   • First, ～.
   • For example, … や For instance, … で補足。
3. 理由2：
   • Second, ～.
   • This is because … や Another example is … などで補足。
4. 結論（まとめ）：
   • That is why I (agree / disagree) with ～.
   • Therefore, I think ～.
   • …ともう一度意見を繰り返して締める。

注意

• 理由を2つ必ず入れる。1つしかないと減点されます。
• 理由の導入に「First, Second, Finally…」と番号を振ることで採点者にもわかりやすくなる。

• 理由を補足する
  • This is because …
  • That is why …
  • Therefore, …
• 対比・逆接を示す
  • However, … / On the other hand, … / Yet, …

3-2. 意見を述べるフレーズ

4. 文法・スタイルチェックリスト

英検準2級プラスでは文法ミスや時制の乱れが致命的な減点要素になることがあります。執筆後のチェックで必ず見るべきポイントをまとめました。

1. 主語と動詞の一致
   • He likes playing soccer. / They like playing soccer.
   • A car is useful. / Cars are useful.
2. 時制の統一
   • 未来なら will + 動詞原形
   • 過去なら 過去形
   • 現在なら 現在形
   • 途中で何の脈絡もなく時制が変わらないように注意。
3. 冠詞 (a / an / the)
   • 可算名詞の単数形には基本 a/an。一度出た名詞や特定の物は the。
   • I saw a movie last weekend. The movie was interesting.
4. スペルミス
   • 特に environment, government, different, business などは要注意。
   • 意外と間違えやすい: receive / believe / opportunity / responsibility etc.
5. 単語数 (50～60語)
   • 短すぎると指示を満たさず、長すぎると超過失点のリスク。
   • 実際に1単語ごとにカウントして調整を。
6. 不要な重複や不自然な長文を避ける
   • 1文に詰め込みすぎず、1文=1アイデアを心がける。
   • 長いカンマや接続詞の連発で読みにくい文にならないよう注意。

予想問題1

Q: Do you think companies should adopt a four-day workweek?
