比較級のクジラ構文について I have no more than 1000yen. を関先生のように訳したら "私は1000円と同じではないように、多く持っていない" というわけわからない文章になりました。どうしたら、 "私は1000円しか持っていない"になりますか？

(1) a horseis 多くの受験生が闇雲に意味を丸暗記している 「クジラ構文 ("no 比較級 than ..")」 ですが、ちょっとしたコツで理解できるようになります。 どう考える? *no 比較級 than ...” を見たら、 「noから、 (1) 比較級、 (2) than... に2つの矢印」 を向けてください。 これですべて理解できます。 no 比較級 than ... (1) (2) (1) 「逆の意味」になる (2) 「･･･ と同じ」と訳す 4 品詞系 (1) no 比較級は強い否定を表し、 「まったく~ではない(むしろその逆だ)」と なります。 (2) no ~ than ... は 「... と同じくらい」 です (than... 「・・・より」 は、 「差」 を表しますが、 no で 「その差を否定 (差がない)」 → 「同じ」となるわけです)。 こ れを有名な「クジラの文」 で確認してみましょう。 A whale is no more a fish than a horse is.
