☆教材解读☆
基数词
表示数目的词称为基数词。其形式如下:
(1)1-10one,
two,
three,
four,
five,
six,
seven,
eight,
nine,
ten
(2)11-19eleven,
twelve,
thirteen,
fourteen,
fifteen,
sixteen,
seventeen,
eighteen,
nineteen
这里除
eleven,
twelve,
thirteen,
fifteen,
eighteen为特殊形式外,
fourteen,
sixteen,
seventeen,
nineteen都是由其个位数形式后添加后缀-teen构成。
(3)21-99整数几十中除twenty,
thirty,
forty,
fifty,
eighty为特殊形式外,
sixty,
seventy,
ninety都是其个位数形式后添加后缀-ty构成。表示几十几时,在几十和个位基数词形式之间添加连词符“-”。21
twenty-one,76
seventy-six。
【拓展】　
基数词记忆规则歌诀:
基数词不难记,找出规律很容易:
零至十二形各异,加上-teen为十几,
thirteen,
fifteen看仔细,eighteen只有一个t;
twenty却是很奇怪,forty本身也不乖,
eighty一起搞例外,跟着也把规则坏;
十位后面是个位,表示数字“几十几”,
表示“几百几十几”,and常把百、十系。
勤学妙记加练习,hundred就是你的好成绩。
