英文詞性-名詞請教 [n] =名詞 , 其中[C][U]的屬性, 會同時出現, 在使用上,如何快速區別?

名詞的［可數性］與［不可數性］的問題，我在ＹＫ＋已經說明過Ｎ次了．

１．多數（英語）名詞背後所代表的觀念與　使用的習慣　都有＂質＂的觀點　也同時有＂量＂的觀點．

例子：
These two (cars) are too much car for you to buy.

第一個cars是可數的．是一個一個的車輛的意思．
第二個car 是不可數的．是指車子的品質／價值的意思．

所以，這句話的意思是：

這兩輛車子對你來說是太貴（太好）了（所以你不該購買）．

２．就拿　牛奶，果汁，水，酒．．．這些東東來說吧．這些都是可以可數也可以是不可數甚至在同樣一句話裡面．
在餐廳哩，習慣上都說：

give me a water.
I like to have two juices.
can I have two more milks?

因為　在那情景之中　都是在講水／奶／酒的＂量＂（一杯水．二杯果汁，二個奶）
所以就被認知為　＂可數名詞＂
