数词
① 基数词:表示数目和数量
a.能熟练读出并写出1-100的基数词和序数词。另外,基数词还有thousand(千),million(百万),billion(十亿)。表示一个具体数字时,thousand, million, billion一律不用复数,如:two hundred, three million;在表示一个不确定数字时则用复数,且和of连用,如:hundreds of(成百上千),thousands of(成千上万),millions of(数以百万计)。
b.掌握数词表示时刻、年份和日期的用法
时刻的读法:顺读法 整点+分钟;如:8:15读作eight fifteen;
逆读法 分钟+past+整点(≤30)如7:16读作sixteen past seven,差额分钟+to+整点(>30)11:45读作fifteen/a quarter to twelve。
年份的读法:1996年读作nineteen ninety-six;2021年读作two thousand and twenty-one,也可读作twenty twenty-one;
日期的读法:2021年10月10日读作October the tenth, two thousand and twenty-one.
c.了解基数词表示世纪和年代的用法:in+the+数词复数表示“在……世纪……年代”。如:in the 1990s表示“在二十世纪九十年代”。
② 序数词:表示顺序
a.掌握序数词的构成:一般情况是在基数词词尾加th。有特殊情况,可用下表口诀巧记:
one, two, three特殊记 | one→first(第一);two→second(第二);three→third(第三) |
eight去t | eight→eighth |
nine去e | nine→ninth |
five, twelve中的ve要用f替,词尾加上th | five→fifth;twelve→twelfth |
几十变第几十,见y变成ie,词尾加上th | twenty(20)→twentieth(第20);thirty(30)→thirtieth(第30);forty(40)→fortieth(第40) |
若是遇到几十几,只把个位数变成序数词 | Twenty-one(21)→twenty-first(第21)
Fifty-seven(57)→fifty-seventh(第57) one hundred and twenty-five(125)→one hundred and twenty-fifth(第125) |
b.掌握序数词表示日期和分数的用法,如:11月9日 November the ninth;数词表示分数时,分子用基数词,分母用序数词,若是分子大于1时,分母加s,(先子后母,子基母序,单子单母,复子复母),如:1/2 one-second, 1/4 one-fourth, 2/5 two-fifths, 4/7 four-sevenths。
- 了解英语倍数和百分数的用法。如:twice(两倍),three times(三倍),15%(15 percent)。
