2、1数词是表示数目或顺序的词，分为 1_与 2_。一些基数词的写法应多加注意，如：forty，eighty 等；基数词的读法，尤其是多位数的读法，应正确读出；hundred，thousand,million, billion表示具体数字时，不用复数形式，而表示不具体数字时，可以用复数；而数词还可以用所有格形式及加连字符相当于形容词，如：oneweeks meeting, five minutes walk,a one-weekmeeting,a five-minute walk,a ten-yearold girl。2-些序数词也应注意它的拼写及词尾形式，如：ninth，twelfth，twen
3、tieth,sixtYfirst 等；序数词前面通常加定冠词 3_ ；和 a 连用表示“4._”等意思。3数词的复习非常简单，因为如果平时认真听讲，做好口语练习，那么这些词汇是最多用到的，所以对考生来讲，再简单不过了。4巧记规律基数词变序数词歌诀：基变序，结尾加上 th。一二三特殊记，结尾各是 t，d，d。八减 t，九去 e，f 来把 ve 替，y 改为 ie，结尾仍有 th。若是遇到几十几，只变个位就可以。参考答案1基数词 2序数词 3the 4又一次 【典型例题精讲】【例 1l(2012，成都)Some scientists think that itwill take_of years
