21、詞一、可數(shù)名詞與不可數(shù)名詞 名詞分為可數(shù)名詞和不可數(shù)名詞。個體名詞和集體名詞屬于可數(shù)名詞，抽象名詞屬于不可數(shù)名詞。 可數(shù)名詞通常有單數(shù)和復數(shù)形式，而不可數(shù)名詞通常沒有單復數(shù)之分，故不能在不可數(shù)名詞前用數(shù)詞或a/an修飾，但可以用some, any, a lot of, lots of, much, a little 等修飾。若表示不可數(shù)名詞的數(shù)量時，一般用“數(shù)詞+量詞+of+不可數(shù)名詞”，如:a piece of news 一則新聞。 常見的不可數(shù)名詞有： news, advice, information, furniture, water, milk, bread, fun, work（注

23、單數(shù)可數(shù)名詞或不可數(shù)名詞，則數(shù)名詞，則be動詞用動詞用is/was；若名詞是復數(shù)可數(shù)名詞，；若名詞是復數(shù)可數(shù)名詞，則則be動詞用動詞用are/were。there be句型的疑問句只要把句型的疑問句只要把be動詞提到動詞提到there前面即可。前面即可。 There is a book on the desk. 桌上有一本書。 There are two pens on the desk. 桌上有兩支筆。 Is there any water here? 這里有水嗎？ Yes, there is. /No, there isnt. 是的，有水。/不，沒有水。 2. 句子中有幾個并列主語時，句子

24、中有幾個并列主語時，be動詞與靠近它的動詞與靠近它的第一個主語保持一致，即第一個主語保持一致，即“就近原則就近原則”。 There is a book and two pens on the desk. 桌上有一本書和兩支筆。 There are two pens and a book on the desk. 桌上有兩支筆和一本書。直擊中考( )1.
