一隻饑腸轆轆的狐狸看見高高的葡萄架上掛著一串串熟透了的紫葡萄，禁不住垂涎三尺。狐狸絞盡腦汁，想了很多辦法，可是他還是夠不到葡萄。最後，狐狸隻好無可奈何地走開，嘴裏還自言自語： “那葡萄一定是酸的 !並沒有我想象的那麼好吃。 ”
人們經常鄙視自己得不到的東西。（這就是我們經常說的“吃不到葡萄就說葡萄酸”。）
A famished Fox saw some clusters of ripe black grapes hanging from a trellised vio all her tricks to get at them，but wearied herself in vain，for she ot reach them. At last she turned away，hiding her disappoi and saying，“The Grapes are sour，and hought.”
It is easy to despise what you ot get.
