[基数词]，不难记，找出规律很容易：零至十二形各异，一个一个单独记。如果表示是“十几”，后面要加-teen。Thirteen，fifteen形异需留意，eighteen只有一个t。表示“几十”要加-ty，twenty，thirty是特例。表示数字“几十几”，连字符号别忘记。

基数词的表示方法1. 英语中，表示数量的词叫基数词。2. ne~twelve(1-12)的拼写和读音各不相同，无规律可循，应逐一记忆。3. 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。
Language pints
4. 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), frty(40), fifty(50)...
5. 21-29直到91-99表示“几十几”，用整数十位数加个位数，中间用连字符“-”把整十位数加个位数，中间用连字符“-”把整十位数和个位数连起来。eg：twenty-three(23); thirty-seven(37); frty-five(45); fifty-tw(52); sixty-ne(61); seventy-three(73); eighty-fur(84); ninety-nine(99).
6. ne hundred“一百”，表示“一百” 用a hundred。要表示200-900，用“数词（tw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。
7. hundreds f+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”，是个模糊数字，不是具体数字。在此结构中，hundreds f 前面不能加数词，hundreds f 后面只能用复数名词或复数代词宾格形式。eg：hundreds f teachers 成百上千的教师 hundreds f them 他/她/它们中数以百计的（人和物）
