1、中考英语语法复习-数词知识点讲解与练习数词指表示数目多少或顺序多少的词，包含基数词（表数目：one,two,three等）和序数词（表顺序：first,second,third等）.（1）基数词 1-12 是独立单词,需逐个记忆。基数词 13-19是个位数词的词干后加-teen 构成。其中 thirteen, fifteen, eighteen 变化不规则。基数词 20-90 是在个位数词后面加 -ty 构成。其中 twenty, thirty, forty, fifty, eighty 变化不规则。基数词 21-99 是在十位数词后面加上个位数词合成,中间加上连字符 - 。例如: 21 tw
2、enty-one,95 ninety-five基数词三位以上的数词, 在百位和十位之间,一般要用连词and ，十万位和万位,亿位和千万位之间通常也要加and。例如: 132 one hundred and thirty-two,1340 one thousand three hundred and forty.（2）英语中没有万，十万，千万，亿这样的单位数词，ten thousand 十千，十千（100010）=一万。故用阿拉伯数字书写千以上的数目时，要由右向左每三位数间留一个空格或写一个逗号。第一个前为thousand；第二个前为million；第三个前为thousand million（英
3、）或billion（美）。每两个空格间或两个逗号间的三位数都被看作“十位数或百位数的千”或“十位数或百位数的百万”。例如56 000 fifty-six thousand和600,000,000 six hundred million。（3）dozen,score,hundred,thousand,million等数词前面有基数词或某些表示数量的形容词时，不加-s。例如 a few hundredmeters 几百米 several million people 数百万人 two thousand teachers 两千位老师，但如表示“几百”“几千”“几百万”等笼统的数目时，则应用-s of
4、构成短语。如：hundreds of books 几百本书 thousands of workers 几千个工人（4）hundred、 thousand、 million作数词时,不用复数,前面可以加上one, two, 等其它数词。用作名词时复数表示“成上”,后面必须要有of,前面可以加上some,many,several等词。如：five hundred(五百), hundreds of(成百上千的), ten thousand(一万), thousands of(成千上万的), millions of(成百万的).专项练习题（30个题*1分） ( ) 1.
