名词分为可数名词和不可数名词。个体名词和集体名词属于可数名词，抽象名词属于不可数名词。
可数名词通常有单数和复数形式，而不可数名词通常没有单复数之分，故不能在不可数名词前用数词或a/an修饰，但可以用some, any, a lot of, lots of, much, a little 等修饰。若表示不可数名词的数量时，一般用“数词+量词+of+不可数名词”，如:a piece of news 一则新闻。 语法聚焦 语法精讲 常见的不可数名词有： news, advice, information, furniture, water, milk, bread, fun, work（注意：work意为“作品；著作”时是可数名词）, housework, homework, weather, fruit, sugar, clothing, traffic, rice, beef, meat, music, rubbish, air, money, ink, tea, progress等。
二、there be句型
1. there be句型表示“有”，表示一种存在关系，be动词后面的名词才是句子的真正主语。be动词的单复数取决于其后面的名词，若名词是单数可数名词或不可数名词，则be动词用is/was；若名词是复数可数名词，则be动词用are/were。there be句型的疑问句只要把be动词提到there前面即可。 There is a book on the desk. 桌上有一本书。
There are two pens on the desk. 桌上有两支笔。
—Is there any water here? 这里有水吗？
—Yes, there is. /No, there isn’t. 是的，有水。/不，没有水。
2. 句子中有几个并列主语时，be动词与靠近它的第一个主语保持一致，即“就近原则”。
There is a book and two pens on the desk.
桌上有一本书和两支笔。
There are two pens and a book on the desk.
桌上有两支笔和一本书。( )1.At that moment he made the girl his own private ______, giving her and her family many riches. （2015广东）
