二.基数词用法
基数词表示人或物数量的多少,意为“……个”,如:one book,
thirty- five children, one hundred policemen …
基数词表示数量的多少,注意与后面的名词保持单复数一致,并注意谓语动词的选用。
E.g.:①There is one apple in the fridge.
* One (一个), apple 用单数,谓语动词用is (单数)
②Millions of foreigners are coming to Beijing in 2008.
* million of (数以百万计), 是复数,foreigner 用复数,谓语动词用复数are
* 不可数名词不可以与基数词连用,没有two water这种说法。
二.基数词用法注意(1)
与汉语不同,在表示“几号房”,“几班”时,数字应放在后面。
如:Room 605 Class 5 Grade 4
Bus 107
二.基数词用法注意(2)
“几百”,“几千”,“几千万”的表示方法。
100 one hundred
200 two hundred (没有“s”)
3,000 three thousand (没有“s”)
几百,数以百计 hundreds of (有“s”)
几千,数以千计 thousands of (有“s”)
几百万,数以百万计 millions of (有“s”)
二.基数词用法注意(3)
注意:自右向左每三位划一个分节“,”,且hundred, thousand, million等用单数形式。

序数词表示人或物的排列顺序,意为“第……”,序数词前面要用“the”.
E.g.: I’ m the third child (第三个小孩) in my family.

解题法宝:
基数词:几个(后面名词常加‘s’)
序数词:顺序,第几(前面常有‘the’)
