一、基数词
基数词表示数量的多少，常用来谈论数目、时间等。
【注意】
对于个位数不为零的十位数，由十位数加个位数构成，中间用连字符号。
eg:
82
——
eighty-two
2)
百位数中若十位数不为零，百位数与十位数之间用and连接，也可省略and；但百位数后直接加个位数时and不能省略。
eg:
106
——
one
hundred
and
six
122
——
one
hundred
(and)
twenty-two
基数词的特殊用法
1.
当hundred,
thousand,
million,
billion等词前面有具体数字修饰时，必须用单数形式。
eg:
There
are
three
hundred
students
in
our
school.
2.
表示“……十”的数词的复数形式可用来表示人的岁数或年代。
eg：He
is
in
his
early
thirties.
他三十出头。
This
took
place
in
1930s.
这发生在二十世纪三十年代。
3.
某些习语中也用复数形式的基数词,表示不确切数字。
eg：数以百计的：hundreds
of
成千上万的：Thousands
and
thousands
of
三三两两地：[by]
twos
and
threes
4.
基数词转化为名词，可用复数形式。
eg：How
many
twos
are
there
in
ten?10里面有几个2？
二、序数词
序数词
表示顺序，在句中常做定语。
基数词变序数词口诀
基变序，有规律
，后面th加上去；
一二三，特殊记，
后面字母t,
d,
d；
八去t，九去e，f来把ve替；
若是遇到几十几
，只变个位就可以；
两位数或两以上，数字只需变个位；
序数词前要加the,
我们一定要牢记。
序数词的用法
1.
序数词用作定语,
前面要加定冠词。
eg:
The
first
truck
is
carrying
baskets.
2.
序数词前面可加不定冠词来表示
“再一”，“又一”
这样的意思。
eg：We’ll
have
to
do
it
a
second
time.
我们不得不再做一次。
3.
表示年、月、日时,
年用基数词表示,
日用序数词表示。
eg:

October
(the)
first,

4.
编码时，既可用基数词也可用序数词。
eg：World
War
I
=
the
First
World
War
第一次世界大战
Page
One
=
the
first
page
第一页
5.
分数的表达：分子用基数词，分母用序数词；当分子大于1时，分母的序数词用复数形式。
eg：two
thirds——2/3
