比較級 (As ~ as)とは

ポイントの解説

比較級の”more than”や”less than”は、二つの比較対象の優劣をつける際に使いますが、二つの比較対象が同等のレベルであると表現をする場合に、”as ~ as”を使います。例えば、”He is as tall as his brother.”（彼は兄と同じくらい背が高い。）という文章があります。これも”more than”を使った比較級と同様に、二つの文章の”He is tall.”と”his brother is tall.”を比較しているのですが、優劣をつける場合には比較対象の形容詞（この場合は”tall”）の前に”more (-er)”や”less”をつけましたが、同等を表す場合には比較対象の形容詞の前後に”as”をつけて、”A as tall as B”（AはBと同じくらい背が高いです。）とします。また、否定文を作る場合には、AはBと「同じほど〜ではない」という意味になり、Aの方が劣っていることを示します。また、”as ~ as”の間に入る単語は形容詞、副詞、”many/much + 名詞”になります。
