命题点2用所给数词的适当形式填空
【技巧点拨】
解答此类试题的关键在于判断所填数词表示的含义。
命题点1数词词义辨析
1.填基数词
表示数量、时刻、年龄等用基数词，如：nine hundred dollars。
2.填序数词
表示顺序用序数词，如：First…Second…Third，in his first grade。
考点精讲
考点1基数词
拓展
1.“基数词+连字符+名词”作定语，名词用单数。如：a three-day holiday一个三天的假期。
2.基数词与表示时间、距离、重量、金钱、度量等词连用，作主语时，常被看作是一个整体，谓语动词用单数。
3.another+基数词+复数名词=基数词+more+复数名词，意为“另外几个；再……” 。如：another three hours=three more hours另外三小时。
4.hundred,thousand,million与billion的用法
（1）表示粗略的数目时,须用复数,其后加of。如：hundreds of people数以百计的人。
（2）表示准确数目时,须用单数。如：six hundred people 600人。
考点2序数词
1.序数词前若无其他修饰词，必须加定冠词the，后通常接单数名词。如：
I’m the first one to arrive here.我是第一个到达这儿的。
2.序数词前若有形容词性物主代词、名词所有格等限定词，则不加the。如：
Today is my thirteenth birthday.今天是我13岁生日。
3.序数词前加不定冠词a或an，表示“又一;再一”，内含顺序性。如：
She had a second child.她有了第二个孩子。
【方法技巧】
基数词变序数词用法口诀
基变序，有规律，末尾加上-th；
一二三，特殊记，结尾各是t，d，d；
th四加起，八去t，九去e，f来把ve替；
整十变y为ie，后跟th莫忘记；
如果遇到几十几，只变个位就可以。
