中高一貫校の学校英語・NEW TREASURE・英検対策を専門とするオンライン個別指導塾です。塾長紹介
英検2級の意見英作文は、最初の1〜2文で自分の立場を明確にすると、その後の理由を組み立てやすくなります。最初から長い背景説明を書く必要はありません。設問が「Do you think …?」なら、まずYes / NoやI think … を使って直接答え、その後に理由を二つ置くと、内容と構成が安定します。この記事では、冒頭の書き方だけに絞って独自30問と模範6題で練習します。
結論|冒頭は「答え→理由の予告」で十分
たとえば、Do you think schools should offer more club activities? なら、I think schools should offer more club activities for students. と始めます。次に There are two reasons. としてもよいですが、語数を節約したいならすぐに First, … と理由へ進みます。
避けたい冒頭
- In recent years, many people have discussed this issue. のような一般論だけで始める。
- 設問と関係の薄い背景を2〜3文書く。
- 自分の意見を最後まで隠す。
- 難しい単語を使うために不自然な導入を作る。
