初识基数词
英语中表示数目多少的数词叫基数词,如one、two、three等。它们的拼写有一定的规律。
1~12是独立的单词,我们要分别记忆它们。
13~19是由相应的个位数和-teen构成,但thirteen、fifteen和eighteen的构成有些不同,需要特殊记忆。
20~90
各整十数的基数词都以-ty结尾。
21~99的非整十数要在十位数和个位数之间加连字符“-”。
例如:
thirty-six
36,fifty-five
55。
基数词的构成规则
一到十二样各异,一个一个单独记。
后加-teen变十几,thirteen、fifteen看仔细。
十八需要看准确,词中只有一个t。
二十到九十整十数后加-ty是规律,twenty不同重点记。
forty挖去字母u,thirty、fifty、eighty更出奇。
