名詞的可數(shù)性的基本特點

名詞根據(jù)其可數(shù)性可分為可數(shù)名詞和不可數(shù)名詞。這兩類名詞的主要特點如下：

1. 可數(shù)名詞的用法特點：可以有復(fù)數(shù)形式；可直接在其前使用不定冠詞或數(shù)詞；可受 these, those, few, a few, many, a good [great] many, a great [good] number of 等修飾。如：

There are five rooms in the apartment. 公寓里有五間房。

There were many things to be done. 有很多事情要做。

A large number of students are Asians. 很多學(xué)生是亞洲人。

2. 不可數(shù)名詞的用法特點：通常沒有復(fù)數(shù)形式；其前不可直接用不定冠詞或數(shù)詞；可用(a) little, much, a great deal, a lot of, plenty of, a large amount of, a large quantity of, some, any 等修飾；要表示數(shù)量不可在前面直接加數(shù)詞，而要用 a piece of 之類的結(jié)構(gòu)。如：

Knowledge is power. 知識就是力量。

They haven’t much furniture. 他們沒有多少家具。
