1. 文を つなぐ When
● 「いつ〜？」ではなく、2つの文を合体させて「〜するとき、…だ」という意味を作ります。
● 前半に置くとき：When S V, S V.（コンマ , が必要）
● 後半に置くとき：S V when S V.（コンマは不要）
2. 時制のルール
● 重要： 「〜するとき」の部分では、未来のことでも will を使わず現在形 にします。
OK: I will help you when you come here. (× will come)
3. Q8 & Q12 のポイント
元の入試問題では「受動態（〜される）」でしたが、今回は「we produce（私たちが〜を作る）」「stop stretching（伸びるのを止める）」のように、自分（モノ）が動作をする形（能動態）に直しています。
