5、詞沒(méi)有復(fù)數(shù)形式。water(水) milk(牛奶) tea(茶) rice(米飯) orange（橙汁）juice（果汁）bread（面包）不可數(shù)名詞的數(shù)量關(guān)系可借助量詞表示，如。a cup of tea two cups of tea16How many修飾可數(shù)名詞 There are some books on the table?(對(duì)劃線部分提問(wèn))How many books are there on the table?特殊疑問(wèn)句：特殊疑問(wèn)句： 17How many的用法：（1）對(duì)there be句型中主語(yǔ)的數(shù)量如:some,five,only one等提問(wèn)時(shí),如果主語(yǔ)是可數(shù)名詞,不管
