六、数词
英语中有两类数词,基数词和序数词,基数词表示数目的多少,序数词表示先后顺序。
1. 基数词

记忆口诀:加上th基变序,123要特别记;八去t,九去e,几十的y变ie,后面加上th;若要变化几十几,只变个位就可以。

4. 序数词的常见使用场景

注意
① 语中没有“万”这个单位,那么10000在英语中需要用thousand(千)作单位,读作ten thousand。
② 百、几千在hundred, thousand后都不要加s,但是在介词短语中需要加s,如hundreds of(好几百的),thousands of(好几千的),millions of(好几百万的)。
③ 年用基数词,但是某月几日,日期在口语中使用序数词。例如June 4, 2009读作June the fourth, two thousand and nine。
④ 分数中,分子用基数词,分母用序数词,序数词后加“s”。如2/5读作 two fifths; 7/10读作seven tenths。Seven tenths of his work is done with computer. 他的7/10的工作是用电脑完成的。
⑤ 序数词前是否需要加定冠词the的情况:

⑥ 序数词和基数词有时可替换。

知识拓展 对于大数字,写成阿拉伯数字时,从个位开始,每三位数字一个单位,用逗号间隔。分别读作thousand(千)、million(百万)、billion(十亿)。例如,1,000读作a thousand;1,000,000读作a million;1,000,000,000读作a billion.
