英语中，表示数量的词叫基数词。
1.one~twelve(1-12)的拼写和读音各不相同，无规律可循，应逐一记忆。
2.thirteen~nineteen(13-19)表示“十几”，在个位数词后加后缀-teen,读作[ti:n]，单词有两个重音。还要注意thirteen(13)、fifteen(15)和eighteen(18)在拼写上的差别之处。
3.twenty~ninety(20-90)表示“几十”，
几十的整十位数是在个位数后加后缀-ty,读[ti]。但要注意加了-ty之后，个位数上的听定就有变化。eg：twenty(20), thirty(30), forty(40), fifty(50)...

one hundred
5.one hundred“一百”，表示“一百” 用a hundred。要表示200-900，用“数词（two至nine）+hundred”构成。在此结构中，无论“几百”，hundred都不能加-s变复数形式。
500 five hundred
600 six hundred
拓展：hundreds of+复数名词或代词宾格是固定结构，表示“数以百计的”、“成千上万的”在此结构中，hundreds of 前面不能加数词，hundreds of 后面只能用复数名词或复数代词宾格形式。eg：hundreds of teachers 成百上千的教师
hundreds of them 他/她/它们中数以百计的（人和物）
