1. 英语中的基数词
(1) 从0到12是独立的单词。
(2) 从13到19的单词全部是以后缀?teen结尾的,如:
fourteen, sixteen, nineteen。
但值得注意的是:thirteen和fifteen是利用序数词(third和fifth)的前面部分加?teen构成的,eighteen则是因为eight本来就是以t 结尾的单数,故没有重复使用字母t。
(3)从20到90的整十数的单词是以?ty结尾的,如:
twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety;整十数的构成形式与13到19这几个单词的构成方式一致,只有 fourteen — forty 需要注意。
(4) “几十几”的表示要借助连字号“-”的帮助,如:twenty-three (23); forty-one (41)等。
2. 英语中常见的货币名词
所有的符号书写都没有单数和复数的区别,但在口语中读出来时,要读其英文单词的读音,而且要有单复数的区别,下面四个符号中,只有中国的人民币没有单复数。
$ 美元符号,英语单词是 dollar(美元),另外还有cent(美分)。£英镑符号,英语单词是 pound (英镑),另外还有penny(便士)。¥ 人民币符号,
使用汉语拼音yuan的读音,另外还有fen(分)。∈ 欧元符号,英文单词是euro(欧元),另外还有cent(欧分)。
