[問題]PP-test1 Q131(structure)

[balaspirit]

131. As sweeteners, there is very small difference between honey and sucrose, although the former does contain minimal quantities of vitamins, minerals, and amino acids.

A:small

參考托福文法大全,裡面說到因為difference為不可屬名詞,因此需要用"little"修飾,可是我有兩個點不懂
1.為何difference在此視為"不可屬名詞"呢?
查了"Longman Advanced Americn Dictionary"裡面的定義 p388:
[C] a way in which two or more things or people are not like each other.
[singular,U] the fact of not being the same as something else, or an amount by which one thing is not the same with another.
不懂要怎麼區分?
2.請問此題裡面的"as"是什麼"詞"呢??我把它當為"連接詞",那不就與"althought"重疊了嗎?

不懂不懂~~

個人是覺得題目挺刁鑽的...
不過 Different用作可數名詞你必須要有冠詞，或是以複數型態出現。
所以"there is very small difference between honey and sucrose"此句中缺冠詞，推測difference為不可屬名詞，以little修飾。(但不可數的difference為何不能用small修飾呢?這種抽象的語感我只能告訴自己下次記住就好。)
As sweeteners -->作為一種甜劑，as是adv(其實我不確定詞性，不過這種用法常見到。)

AS應該是介詞，介詞+名詞；ADV通常是修飾V或ADJ
