三、 不可數(shù)名詞的家務(wù)事

　　1. 不可數(shù)名詞沒有復(fù)數(shù)，當(dāng)它作句子的主語時，謂語動詞要用單數(shù)形式。如：

　　The food is very fresh.　食品很新鮮。

　　2. 有的不可數(shù)名詞也可以作可數(shù)名詞，有復(fù)數(shù)形式，但他們的意義往往發(fā)生變化。如：

　　water (水) → waters (水域)

　　orange (橘汁) → oranges (橘子)

　　3. 很多的不可數(shù)名詞表示泛指時為不可數(shù)，表示種類時就可數(shù)，但意義大多不發(fā)生變化。如：

　　fruit → fruits food → foods

　　fish → fishes hair → hairs

　　用所給名詞的適當(dāng)形式填空。
