請問 How many candies do you have?I have more candies than yours.  這句有甚麼錯?

我猜你問的是I have more candies than yours. 這句有什麼錯。
文法上, than可以是連接詞(and, or)或介詞(in, before, 等等). 假如當連接詞, 兩邊必須是對等的. 左邊是句字, 右邊也是句字, 像toming88已經指出，I have more candies than you have (candies).從這個Wiki(https://en.wikipedia.org/wiki/Than), 文法學家認為than是連結詞. 在當代英語, than也可以當介詞. 這有時會造成語意上的模糊. 比如說, John likes you more than Jack. 這可以是John和Jack都喜歡你, 但John喜歡你多一點 (John likes you more than Jack likes you). 另一個語意是John喜歡你和Jack, 但John喜歡你多一點(John likes you more than John likes Jack). 你可看出比較的東西是不同的. 當語意不會造成誤會時, 表達上很清楚, 把than當成介詞使用沒什麼問題. I have more candies than yours是可以的, 最少在口語的表達上, 聽的人很明顯知道你要說什麼. 但當語意有模糊地帶時, 最好是把than當成連結詞. 考試時或和很重試英文文法的人講話時, 應該還是回到正統, 把than當成連結詞: I have more candies than you have.

I have 6 candies;while you've 5.
I have one more candies than you do.
(not yours)
"yours" is pronoun possesive
=This 5 candies is yours
=your possession.
Not you have=I have; not yours.
ie:-I have more candles than you "do".
=used instead of another verb(have);
ie:-You have candles, and so do I=(have I)

它的錯誤是在　＂答非所問＂．也就是＂回答錯問題＂．
所提出的問題是：＂你有幾隻糖果兒？＂
所獲得的回答是：＂我有的糖果兒比你有的糖果兒還要多．＂

不過在政治場合裏面，醬子的回答卻是標準答案．
