一、可數(shù)名詞是可以用來計數(shù)的名詞.可數(shù)名詞有單數(shù)和復數(shù)形式.如：desk-desks,apple-apples等.不可數(shù)名詞是不可以直接用來計數(shù)的名詞.不可數(shù)名詞沒有復數(shù)形式,只有單數(shù)形式.如：some bread,a little milk等.二、單數(shù)可數(shù)名詞表示泛指時,前面要用不定冠詞a(an),表示特指時,前面要用定冠詞the; 而不可數(shù)名詞前不能用a(an)修飾,表示特指時,前面一定要用定冠詞the.如：He is a factory worker.他是一名工人.No one can see air.沒有人能看見空氣.三、可數(shù)名詞和不可數(shù)名詞前都可以用some,any,a lot of,lots of 等來修飾,表示"一些,許多".如：There are some oranges on the desk.桌子上有一些桔子.There is a lot of water in the bottle.瓶里有許多水.四、可數(shù)名詞前可用具體的數(shù)詞來表示具體的數(shù)量.如：two apples,four books等.不可數(shù)名詞前通常用"單位詞+of"來表示數(shù)量.如：a piece of paper,three pieces of paper等.五、可數(shù)名詞作主語時,謂語動詞的單復數(shù)與主語的單復數(shù)保持一致.如：This picture is very beautiful.這幅畫很美.不可數(shù)名詞作主語時,謂語動詞要用單數(shù)形式,但是不可數(shù)名詞前有復數(shù)"單位詞"時,謂語動詞要用復數(shù)形式.如：There are two cups of tea on the table.桌上有兩杯茶.六、對可數(shù)名詞前的修飾語提問用how many; 對不可數(shù)名詞前的修飾語提問用how much.如：How many apples are there in the box?盒子里有多少個蘋果?How much tea is there in the cup?杯里有多少茶水?注意：對不可數(shù)名詞前的"單位詞"的修飾語提問時,疑問詞用how many.如：How many pieces of bread are there on the plate?盤子里有多少片面包?
