什么是数词呢？数词是表示事物的数量或顺序的词。一般可分为基数词和序数词。首先，让我们先了解基数词。基数词是表示数量多少的数词。同学们，你们能认读这些基数词吗？下面老师来告诉你一个口诀，有了它就可以容易记住他们了。Let’s
go！
1到12分别记，13到19都带-teen，
11
eleven，12twelve特别记。
13
thirteen
要注意，15fifteen要牢记，
18eighteen少了e，19nineteen别漏e，
说到几十怎么办，ty来把teen代替，
加个横杆于几十几，
将and来连接一百几。
同学们都记住了吗？在生活中，我们都会经常用到基数词来表达具体的数量，例如：我家里有六口人，we
can
say
:there
are
six
people
in
my
family.
I
can
see
ten
sheep
in
the
picture.图片里我看到10只绵羊。那同学们，你能在生活中找到更多的基数词的表达法吗？Please
look
at
the
picture
and
try
to
say.
Right!
The
apples
are
fifty
percent
off
today。
Great！It’s
5:30.
Let’s
go
to
the
playground.
Yes!
He
was
born
in
1990.
Now
he
is
thirty
years
old.
Wonderful!
Fifty
plus
to
is
fifty-two.
同学们，我相信大家都能观察到基数词一般有以下用法：
表示具体的数量，如：four
people
表示年份，如：In
2020
表示时间,
如：It's
5：30.
表示身高，体重，年龄，如：three
years
old
表示价格，如：fifty-five
yuan
表示数学算式的数,
如：Two
plus
one
is
three.
那是否生活中所有的数都是基数词呢？Now
let’s
look
the
pictures
and
find
the
answer.
Yes,
She
won
the
first
prize
in
the
running
competition.(她在跑步比赛中赢得第一名）
Right！The
teachers’
office
is
on
the
second
floor.（教师办公室是在二楼）
Great!
New
Year's
Day
is
on
Jan.
1st.
(新年是在1月1日）
其实，我们就很容易发现表示事物的顺序用序数词，其前面一般要加定冠词the.
如：on
the
second
floor
但是呢，当序数词前有形容词性物主代词修饰时，序数词前面不用the.
如：my
twelfth
birthday
我的十二岁生日。
那序数词最常见的表达法有：
1.表示顺序排序：如：Sunday
is
the
first
day
of
a
week.
表示日期的几日，如：March
the
first
3.表示几岁的生日，如：My
twelfth
bithday
4.表示楼层，如：on
the
second
floor
那序数词怎样写呢？
一般情况下：在基数词后加-th
就可以变成数词了，而且th的发音发[θ]
如：
four
-
fourth
sixteen
-
sixteenth
可是有些情况下不是按照这规律，怎么办呢？没关系，老师也有规律帮助大家。Let’s
go!
1，2，3
特殊记，结尾各是st，nd，rd，one的序数词是first，two
second，three
是
third。Let’s
read
it
again。
8减t，9去e，f来把ve替，ty要换tie，结尾需加th。8
去t再加th变成eighth。那下面nine、five、twelve你能根据规则说说怎样变化呢？大家看看是否跟老师写的一样？Nine，9去e所以变成ninth。Five当中的ve要用f来代替，twelve也是同样的ve变f再加th。读twelfth。Ty也变成tie，那把y变成ie别忘记加上th，twentieth.
那同学们，下面的twenty-one，ty也变成tie吗？
那我们看看这个规律，如是碰到几十几，改变个位就可以，所以我们几十twenty不变，改变各位，one，变first，读成twenty-first。这些基数词的变化规律要牢牢记住哦。Now
let’s
read
these
words
again.我们再一次读这些基数词吧。
好的，同学们有没发现老师都在序数词后面都加了括号，括号里的是什么呢？That’s
Right.
那是序数词的缩写形式。观察下，缩写形式与数字之间有什么联系呢？现象大家也发现了，序数词所有形式是在相应的数字后面加上单词的后两个字母，如first第一，缩写
1st，second，第二，缩写：2nd
.
同学们，今天我们学到数词都记住了吗？I
have
two
number
friends,
they
are
Cardinal
brother
and
Ordinal
sister
(基数词哥哥叮叮，序数词妹妹美美）but
they
are
sick.
Let’s
see
what
happened?
Oh,
Let’s
help
them!
Let’s
