英語の言い換え：会話・ビジネスメール・正式な要約
予約システムの導入案を、同僚との会話、丁寧な口頭説明、仕事のメール、正式な要約で伝え分けます。英語には日本語の「です・ます」にそのまま対応する形がないため、語句の選び方や提案の仕方で調子を整えます。日本語では省きやすい「誰が何をするか」も、英語では主語や節を使って示しましょう。文章を簡潔にしても、効果の見込み、試験の範囲、追加試験の提案は残します。

会話・メール・要約での表現を比べる
文体を変えても、可能性・根拠・手順を保つ
「We could reduce waiting times by about ten percent if we implement the new booking system.」の could はここでは過去ではなく実現の可能性を控えめに示し、should は「〜したほうがよい」という勧めを表します。親しい会話では短縮形の that's や But が自然で、丁寧な口頭説明では I think we should、仕事のメールでは I propose that や I recommend、However を使うと、提案と留保を整理して伝えられます。
動詞の implement・reduce・approve を名詞の implementation・reduction・approval にすると、「私たちが何をするか」から「導入・削減・承認そのもの」へ文の焦点が移ります。「reduce waiting times by about ten percent」では by が削減幅を示し、「a reduction in waiting times of about ten percent」では in が削減の対象、of が削減幅を示すので、日本語の「の」だけを頼りに前置詞を選ばないようにしましょう。「Trials at two more branches are recommended」の受け身は提案者を前面に出さない要約に向きますが、導入の提案と追加試験の勧めは別の内容なので、片方だけで両方を伝えたことにはなりません。
どの文体でも「約10％」「一支店で二週間の試験に基づく試算」「さらに二支店で試してから導入拡大の承認を求める」という内容を保ち、could を will に変えて効果を確実なものとして伝えないことが大切です。
