小升初英语语法专项复习：数词
【知识梳理】 基数词：
1. 1—12的基数词是独立的单词，即： one，two，three，four，five，six，seven，eight，nine，
ten，
eleven，twelve。
2. 13—19的基数词以-teen结尾。如： fourteen，seventeen等，但13，15，18较特殊，13—thirteen 15—fifteen 18—eighteen。
3. 20—90的整十位均以-ty结尾。如： sixty，ninety，但20，30，40，50，80较特殊，20—twenty， 30—thirty，40—forty ，50—fifty ，80—eighty。
4. 十位数与个位数之间要加连字符号“-”，如：28—twenty-eight，96—ninety-six
5. 百位和十位(若无十位则和个位) 之间加and，如：148—one hundred and forty-eight ，
406—four hundred and six。
6. hundred(百) ，thousand(千) ，million(百万) ，billion(十亿) 等前面即使有具体的数词，也
不能在它们的后面加s。如：600—six hundred，8百万—eight million。
7. 1000以上的数字，从后往前数每三位加一个逗号“，”第一个逗号前为千(thousand) ，第二
个逗号前为百万(million) ，第三个逗号前为billion(十亿) 。英语中无“万”这个词，我们可以用“几十个千(thousand) ”表示几万，“几百个千(thousand) ”表示“几十万”。 如：2，510＝two thousand five hundred and ten；
84，296＝eighty-four thousand two hundred and ninety-six；
274，350＝two hundred and seventy-four thousand three hundred and fifty。
8. hundred，thousand，million用复数形式修饰名词时要用“of＋复数名词”，如：数以百计的
年轻人
hundreds of young people；数以千计的书thousands of books。注意：hundreds of ／thousands
of／millions of ＋复数名词，其前面不能加具体的数词，但可加several或 many。
序数词：
由基数词转变而来，表示“这是第n个” 1. 口诀巧记基数词变序数词：
一. 二. 三，特殊记， (first，second，third)
八去“t”，九去“e”， (eight—eighth，nine—ninth) “ve”要用“f”替， (five—fifth，twelve—twelfth)
见“y”变成“i”和“e”，词尾加上“th”，(twenty—twentieth，forty—fortieth) 若是遇到几十几，只变个位就可以。 (twenty-five—twenty-fifth) 其余情况均在基数词后加th。
如： six—sixth, nineteen—nineteenth , hundred— hundredth, thousand—thousandth等。
2. 序数词有时用缩写形式：
first——lst second——2nd third——3rd
fourth——4th sixth——6th twentieth——20th twenty-third——23rd
其中lst，2nd，3rd为特殊形式，其它的都是阿拉伯数字后加上th
【例题精讲】
1. Thursday is the f______ day of the week in the UK.
【答案与解析】序数词的用法及文化习俗。Thursday是周四，但在英国的周历中，周日是一周的第一天，所以周四是一周的第五天而不是第四天，故答案为fifth。 2. Women’s Day is on the e______ of M_______.
【答案与解析】 月份. 序数词的用法及节假日文化常识。妇女节是每年3月8日，故答案分别填eighth和March。
3. ( ) How do we say “99,118”?
A. ninety-nine thousand and one hundred and eighteen B. ninety-nine thousands one hundreds and eighteen C. ninety-nine thousand one hundred and eighteen
D. ninety-nine thousands and one hundred and eighteen 【答案与解析】基数词的读法。注意：1,000以上数目的读法：自右向左每三位划一个分节“’”，第一个分节读thousand, 第二个分节读million, 第三个分节读billion或thousand million ，且hundred, thousand, million等用单数形式。注意，百位数hundred与十位数(或个位数) 之间要用and连接。十位数与个位数之间要用连字符号“-”。故选C。
