掌握数词的用法非常重要,请你写出数字1~30,并总结规律。
(1)________ (2)________ (3)________
(4)________ (5)________ (6)________
(7)________ (8)________ (9)________
(l0)________ (11)________ (12)________

(22)________ (23)________ (24)________
(25)________ (26)________ (27)________
(28)________ (29)________ (30)________
你总结出数词1~30有什么规律了吗?下面我们一起总结一下。
(1)从13~19都是以teen结尾,均读做/ti:n/除thirteen,fifteen外,fourteen,sixteen,seventeen,nineteen均是在four,six,seven,nine后加-teen;eighteen因eight是以“t”结尾,故直接加-een.
(2)twenty,thirty均是以-ty结尾,读做/ti/。从21~29均是在twenty后加“-”连字符,one,two,three…nine直接跟后。
小博士:仔细观察下面的基数词和对应的序数词的区别和变化,你会发现这种变化是有规律的,你能归纳出来吗?请根据规律填出所缺的基数词和序数词,并特别注意黑体字的词。
one | first | eleven | eleventh | twenty-one | twenty-first |
two | second | twelve | twelfth | twenty-two | twenty-second |
three | third | thirteen | thirteenth | twenty-three | twenty-third |
four | fourth | fourteen | fourteenth | twenty-four | ______ |
five | fifth | fifteen | ______ | twenty-five | twenty-fifth |
six | sixth | sixteen | sixteenth | twenty-six | twenty-sixth |
seven | ______ | seventeen | seventeenth | twenty-seven | twenty-seventh |
eight | eighth | eighteen | eighteenth | twenty-eight | twenty-eighth |
nine | ninth | nineteen | nineteenth | twenty-nine | twenty-ninth |
ten | tenth | twenty | twentieth | thirty | thirtieth |
thirty-one | thirty-first fortieth ninetieth | hundred | hundredth | ||
forty | thousand | thousandth | |||
ninety | million | millionth | |||
我找到规律了!请看:
1 英语序数词1~19,除first,second,third等特殊形式外,其余的一般是在相应的基数词后加-th构成。
2 有几个序数词加-th时拼法不规则,要注意。如fifth,________ ________ ________。
3 十位整数的序数词的构成方法是先将其基数词的词尾“ty”中的“y”改为“i”,再加“-eth”。如________。
4 基数词“几十几”变成序数词时,只需将个位数变成序数词,十位数不变。如________。
