数词的用法及分数的表达法
【知识梳理】
数词：表示数量或顺序的词叫做数词。数词分为两大类，即基数词和序数词。基数词表示数量，如:one,
two,
three,
four……;序数词表示顺序，如:first,
second,
third,
fourth……序数词前一般要加the。
考点一：基数词和序数词
[考点透析]
数词是表示数目和顺序的词。数词又分为基数词和序数词两类。基数词表示数目，序数词表示顺序。
[温馨提示]
1、序数词作定语时前面一般要加定冠词the。但是其前若有this，that，my等限定词修饰时，则不加the。
例如：Our
classroom
is
on
the
second
floor．我们的教室在二楼。
This
is
our
first
lesson
this
term.
这是我们这学期的第一节课。
2、表示年、月、日时，年用基数词，日用序数词。如：July
1st，1949读作July
the
first，nineteen
forty
nine.
3、表示年代时，在年份的阿拉伯数字后面加 s或's。
如：in
the
1990s在二十世纪九十年代

1．“When
is
your
mother’s
birthday,
Tina ”“It’s

July
the_________.”
A．twenty
B．ninth
C．five
(贵阳卷)
2．－We’ll
be
back
for
our
school’s________
anniversary
ceremony.
(黄冈卷)
－I

That
means
you’ll
have
a
get-together
with
your
classmates
in
________
years.
A．fifteen；seven
B．fifteenth；seven
C．fifteen；seventh
D．fifteenth；seventh
[考题解答]
1．B。在日期表达中，“日”用序数词。
2．B。本题考查基数词、序数词的用法。前句应为“我们将回去参加学校的第十五个周年纪念日典礼”，此处应用序数词fifteenth；in
seven
years在句中表示“七年后”的意思。
考点二：分数的表达法
[考点透析]
英语中分数的表达方法是：分子用基数词，分母用序数词，如1/2：one
second；如果分子大于1时，分母则用复数形式，如2/3：two
thirds。请记住下面的口诀：
分子基数词，分母序数词，分子大于1，分母加—s。
[品味中考]
Nearly
________
of
the
earth
_______
covered
by
sea.
(无锡卷)
A.
three
fourth；is
B.
three
fourths；is
C.
three
fourth；are
D.
three
fourths；are
[考题解答]
B。本题考查分数的表达法。正确表达是：分子用基数词，分母用序数词，分子大于1时，序数词词尾加—s，故排除A和C；分数所修饰的名词作主语，谓语动词取决于分数所修饰的名词，此句中the
earth是不可数名词，故选B。
考点三：hundreds／thousands／millions
of的用法
[考点透析]
hundred，thousand，million等表示数量的词的用法如下：
1．当前面有数词以及many，several等词修饰时，用单数形式，后面直接跟复数名词。如：two
hundred
students
200名学生，several
thousand
enemies几千敌人
2．当这些词前面没有数词而后面有of时，则一定要用复数形式，表示笼统的数目。如：thousands
of
dollars数千美元
[品味中考]
Because
of
Project
Hope，________
children
have
better
lives.
(天津卷)
A.
thousand
B.
thousands
C.
thousand
of
D.
thousands
of
[考题解答]D。thousand前有具体数字时，不能用复数形式；表示约数时常常用thousands
of，意为“成千上万的”。
[巧学妙记]
数词变化规律及读法口诀
两大数词基和序，前表数量后第几。
构成先谈基数词，1至12请认真记。
13至19teen结尾齐，ty结尾表示几十。若要表达几十几，几十短横1到9。
One

一百记，若表几百几十几。
几百
and几十几，基数规律上述里。
再把序数谈仔细，第一至三独立记。第四至十九结尾th,第廿到九十有规律。
基数基础y变ieth。第几十几有特例，第几十由基数起，几用序数有道理。
第一百one
