- 1薄如紙、像紙一樣薄
If something is paper-thin, it is extremely thin — as thin as a sheet of paper, or close to that. You can say it of walls, ice, fabric, or a slice of meat. People also stretch it: a paper-thin lead in a game, a paper-thin excuse, meaning the gap or the reason is so slight it might as well be nothing. It sounds a little vivid and informal; in a science class you would more likely say very thin, or give a number. Though actually it does not mean made of paper. A paper-thin wall is still a wall. Before a noun, English often keeps the : paper-thin walls.
paper-thin 指極薄，像一張紙那麼薄，或接近那樣薄。可以用來形容牆、冰、布料，或一片肉，例如「paper-thin walls」，放在名詞前面時通常保留連字號。
人們也會延伸用它來說差距或理由，例如「a paper-thin lead」（一點點的領先）或「a paper-thin excuse」（一個站不住腳的藉口），表示那個差距或理由小到幾乎等於沒有。這種用法比較生動、偏口語；在科學課上，比較會說 very thin 或給出數字。
它不是指用紙做的。paper-thin 的牆仍然是一面牆，只是很薄。
From the word’s history
