gold is of much value這句話用了什麼文法

Question

gold is of much value這句話用了什麼文法呢？為什麼不用gold is cost much value呢？

Answer 1

英文中有一種用法是 of + N 等於形容詞的,這類的名詞常見的有：of use = useful --> of much/great use = very usefulof help = helpful --> of much/great help = very helpfulof importance = important --> of much/great importance = very important所以你的句子：Gold is of much value.= Gold is very valuable.此外, is是動詞,cost是原形動詞,兩者不會放在一起,所以你的改寫反而是不正確的！若要用cost的話或許可以寫成：Gold costs a lot (of money,不用value).

gold is of much value這句話用了什麼文法呢？為什麼不用gold is cost much value呢？ Gold is of much value.  這句話的主詞是 Gold (黃金)， is 是 be 動詞， be 動詞之後為補語， 主詞的補語通常是名詞或形容詞， 在此， of much value 是形容詞， 因為介係詞 (of) + 名詞 (value) = 形容詞of value = valuable; of much value = very valuableGold is of much value. = Gold is very valuable. 黃金非常有價值 (貴)再舉一例：  He is a man of ability. = He is an able man.              他是個有能力的人  (能**)
