英語名詞分可數(shù)的和不可數(shù)兩種�？蓴�(shù)名詞指一般動(dòng)物和事物，如“Man/ friend/ driver/ student/ dog/ cat/ boat/ egg/ gun/ hand/ head/ lamp/ road/ table/ car ”等等�？蓴�(shù)名詞有兩個(gè)數(shù)，即單數(shù)和復(fù)數(shù)。單數(shù)名詞可以和不定冠詞“ a/ an”或其他名詞限定詞(determiners)連用;復(fù)數(shù)名詞可以和數(shù)目詞，如“many/ a few/ some/ a lot of”等連用。

　　不可數(shù)名詞指物質(zhì)名詞(material nouns)和抽象名詞( abstract nouns)，如：“air/ butter/ grass/ money/ sand/ water/ carefulness/ joy/ peace”等等。不可數(shù)名詞可以和數(shù)量詞，如“much/ a little/ little/ a great amount of”等連用。不可數(shù)名詞只有單數(shù)，沒有復(fù)數(shù)“-s”的形式。

　　有些人對名詞數(shù)的概念不很清楚，對數(shù)目詞(expressions of number)和數(shù)量詞(expressions of quantity)也有些混亂，結(jié)果把數(shù)目詞用在不可數(shù)名詞之前或隨意在不可數(shù)名詞后面加上復(fù)數(shù)詞尾 “-s”，這些都是語法上的錯(cuò)誤。例如：

　　① Our workshop has ordered some new equipments from Germany.

　　雖然有些人把 equipment(配備)當(dāng)成可數(shù)名詞，但是它是不可數(shù)的，不可有“-s”。

　�、� My teacher gave me some sound advices. 應(yīng)該是“advice”。

　�、� Do you have any special informations for me? “Information”才對。

　�、� Most furnitures in my house are made of wood. 應(yīng)該是“furniture……is……”

　�、� Today, I have many new works to do. 必須是“a lot of new work”才是。

　�、� Don't walk on the grasses. 應(yīng)該用“grass”。

　�、� Our foreign students have made great progresses in their studies. “Progress”(進(jìn)步)不可數(shù);不可有“-es”。

　�、� All his money are kept in the bank. “Money”(金錢)屬不可數(shù)名詞;動(dòng)詞要單數(shù)的“is”。
