基数词13-19
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。
twenty
20
thirty
30
forty
40
fifty
50
sixty
60
seventy
70
基数词20,30,40...
eighty
80
ninety
90
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)...
twenty
-one
21
twenty
-two
22
twenty
-three
23
twenty-four
24
twenty-
five
25
twenty
-six
26
基数词21-29
4.21-29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);
forty-five(45);
fifty-two(52);
sixty-one(61);
ninety-nine(99).
one
hundred
100
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

600

基数词的规律总结
基数词的规律顺口溜
英语数词不难记，找出规则就容易。
零至十二形各异，一个一个单独记。
后面加teen变十几，thirteen,
fifteen看仔细。
eighteen只有一个t，两个音节念清晰。
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。
