2023中考英语知识点数词

  中考英语知识点数词 1

  Ⅰ.直击中考

  数词分为两种:基数词和序数词,表示人或事物数量多少的数词,叫基数词,如one,two,three,ten;表示人或事物的顺序的数词叫序数词,如first,second,third,fourth等。在中考中主要考查的是:

  (1)基数词、序数词、分数词、小数、百分数、倍数的表达;

  (2)日期、时刻、年代、年龄的表示法;

  (3)掌握表数目的名词(如dozen,score,hundred,thousand,million等)的有关用法,以及“许多”的表示法。平时备考时,考生应将用基数词或序数词表示物的正确形式加以对比、归纳、总结、熟练掌握以及牢记常用的数位名词所表示的数目大小等。

  Ⅱ.知识精讲

  1)数词知识结构

  2)数词知识点剖析:

  A.基数词

  1.基数词的构成及读法

  ①1-12的构成为独立单词

  ②13-19的构成都以后缀-teen结尾,但thirteen,fifteen,eighteen为不规则变化

  ③20-90的构成都以后缀-ty结尾,但twenty,thirty,forty,eighty为不规则变化

  ④21-99的构成是在十位数和个位数之间加连字符-25 twenty-five

  ⑤三位数101-999的构成要注意百位数和十位数(个位数)之间用and连接。 nine hundred and one

  ⑥英语中没有“万”这个单位,1000以上而不到100万的数词都用thousand表示

  ⑦百万 1,000,000:one (a) million

  ⑧千万 10,000,000:ten million

  ⑨亿 100,000,000:one (a) hundred million

  ⑩十亿 1,000,000,000:one (a) thousandmillion(等于美国英语a billion)

  注:英语数字中,只有hundred后才加and

  2.基数词的作用

  ①作主语Two of the girls are from California.姑娘中有两个来自加州。

  ②作表语He is a little over five.他才五岁多一点。

  ③作宾语Give me two.给我两个。

  ④作定语The river is about eighty miles long.这条河大约八十英尺长。

  ⑤作同位语You two take these seats.你们两个坐这里。

  3.基数词的特殊用法

  (1)表示“几十年代”或“几十岁”时,用逢十的基数词的复数形式。如:

  in the1990s 20世纪90年代;in ones twenties在某人20多岁时

  (2)用在习语中。如:in twos and threes三三两两地

  4.基数词的注意事项

  (1)几十几的基数词的十位数与个位数之间要用连字符"-"连接。如:

  eighty-five85;twenty-six 26

  (2)三位数的基数词须在百位和十位(若无十位则和个位)之间用and连接。如:three hundred and sixty-five 365;two hundred and six 206

  (3)基数词的复数形式。当基数词hundred,thousand,million,billion等词前有具体数词或several修饰时,必须用单数。如:

  severalhundred years ago几百年前;twothousand students两千个学生

  B.序数词

  1.序数词的构成

  ①序数词多数由"基数词-th"构成,序数词前一般加定冠词the

  ②少数序数词构成属特殊情况

  One-first two-second three-thirdfive-fifth

  ③以y结尾的十位整数,先将y改为i,再加-eththirty-thirtieth

  ④21以上的多位数,要将末位数改为序数词,前面其他位数仍用基数词eighty-three—eighty-third

  ⑤序数词的缩写形式由阿拉伯数字加序数词的后两个字母构成

  first-1st second-2nd

  2.序数词的用法

  ①作主语The third of the month was a holiday.

  ②作表语Who was the third?

  ③作定语We live on the fifth floor.

  ④作宾语I was among the first to learn of this.

  ⑤作同位语Who is that man,thefirst in the front row?

  ⑥作状语When did you first meet him?

  注:有时序数词并不指顺序,而是表示“再一,又一”的意思。此时序数词前要加不定冠词I want to make a second try.

  3.序数词的应用

  序数词应注意的几点事项:

  1.多位数的基数词变成序数词时,只需将末位基数词变成序数词,前边的基数词不变。如:

  forty-two 42 forty-second第42

  nine-hundred 900 nine-hundredth第900

  2.当序数词用阿拉伯数字表示时,必须在数字后加上序数词的最后两个字母。

  如:21st第21;32nd第32

  3.序数词前一般要用定冠词the,如果序数词前用a或an时,则表示“又一;再一”(没有具体范围的限制)。如:

  Though he had failed twice,he wanted to try a third time.

  The little monkey had had three apples,and he wanted to eat a fourth one.

  C.数词表示方法

  1.年、月、日、时的写法和读法

  ①表示日期用序数词,前面加定冠词

  3月8日 March the eighth

  ② 年份一般分为两部分读,先读前两位数,再读后两位数

  1949 nineteenforty-nine

  ③ 以上时间合在一起的写法

  1955年10月1日上午10点 10:00 a.m.October 1st,1955

  2.分数的表示法

  分数由基数词和序数词构成,基数词代表分子,序数词代表分母,除了分子为1的情况,序数词都要用复数形式。带分数中的整数用基数词表示,并用and和分数隔开。

  14 one-fourths 3-25 three and two-fifths

  3.小数、百分数的表示

  1)小数的表示6.4 six point four

  2)表示百分数用"基数词+percent(per cent)"形式50% fifty percent

  4.年份和日期

  1)年份的读法为每两位数读一个词。

  如:1950读作nineteen fifty

  1800读作eighteen hundred

  2000读作two thousand

  2)日期的读法有两种

  (1)先月后日,日子要读成序数词。

  如:9月29日可读作September(the) twenty-ninth

  (2)先日后月,在月份之前加Of。

  如:9月29日也可读作thetwenty-ninth of September

  3)年月日同时出现,年代放在最后,年代前用逗号隔开。

  如:2005年2月1日可写成the first ofFebruary ,2005或February( the) first,2005

  5.时间和钟点

  6:00读作six (oclock)

  7:30读作seven thirty/half past seven

  9:45读作nine forty-five/a quarter to ten

  2:15读作two fifteen/a quarter past two

  6.编号的表达

  1)事物名词(不加冠词)+基数词。

  如:Lesson One,Part Three,ChannelFive,Gate Nine,World War Ⅱ

  2)定冠词+序数词+事物名词。

  如:the first lesson,the third part,thefifth channel,the ninth gate,

  7.加减乘除的英语表达

  plus/and加,minus减,time/multiplied by乘,divided by除。如:

  1)12 +8=? How much is twelve plus/and eight?

  2)40—11=29,Fortyminus eleven is/equals twenty nine.

  3)3×6 =18, Three times six is/equals eighteen.
