2022届中考英语语法复习-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
twenty-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（1000×10）=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）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
hundred
meters
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
thousa
nd(一万),
thousands
of(成千上万的),
millions
of(成百万的).
