数词
【定义】表示数目多少或顺序先后的词叫做数词。英语中，数词主要分为基数词和序数词两类。
一、基数词
表示数目多少的数词称为基数词。其基本构成如下：
1.
1~12
的英文表达没有规律可循，需要同学们逐个牢记。
2.
13~19
的英文表达由“
个位数+
后缀?teen”构成。其中13(thirteen)
，15(fifteen)，18(eighteen)发生拼写变化。
3.
20~99
之间的整十的数，由“2~9+后缀?ty”构成。其中20(twenty)，30(thirty)，40(forty)，50(fifty)，80(eighty)
发生拼写变化。个位数不为零的两位数，在十位数与个位数中间加连字符“?”。如：25(twenty?five)，34(thirty?four)。
4.
整百的数由“百位数+hundred”构成；非整百的三位数，在百位数与十/
个位数中间要用and
连接。如：325
（three
hundred
and
twenty
?five），
503(fivehundred
and
three)。
5.
整千的数由“千位数+thousand”构成；非整千的四位数，由千位数直接加百、十、个位数构成。如：2,138（two
thousand
one
hundred
and
thirty?eight）。
6.
hundred，thousand，million，billion
的前面有具体数字时不能用复数形式，但在表示不确切的数时，要用复数形式，后面要加of。如：5,000（five
thousand），数以百计的（hundreds
of）。
二、序数词

1.
1~19
除了first

(第九)，twelfth(第十二)的拼法变化。
2.
20~99
20
以上的序数词，先将基数词词尾y
改成i，然后再加?eth。如：twentieth(第二十)。非整十的序数词，它的十位数为基数词，只将个位数变为序数词。如：forty?first
(第四十一)，fift?second
(第五十二)，ninety?sixth
(第九十六)。
3.
100-999,1000-9999整百/

三、完形填空
I
strongly
believe
the
right
words
at
just
the
right
time
could
change
someone’s
life.
When
I
was
3
years
old,
my
parents
__1__
I
was
totally
deaf.
But
from
the
third
grade,
they
decided
to
put
me
in
a
“mainstream”
school
where
all
of
my
classmates
had
__2__
hearing.
So
I
was
the
only
deaf
child
at
Blue
Creek
Elementary
School.
From
the
first
day
there,
the
other
kids
often
__3__
me
and
called
me
names
mainly
because
of
my
hearing
aid
(助听器)and
the
way
I
talked.
I
was
worried
throughout
elementary
school.
Besides
the
problem
of
“fitting
in”
with
the
other
students,
I
also
had
__4__
with
most
of
my
schoolwork.
One
morning,
Mrs.
Jordan,
my
fifth-grade
teacher,
asked
__5__
a
question
in
her
math
class.
She
was
a
large
woman
with
a
voice
that
__6__
the
walls
of
her
tiny
classroom,
and
it
could
even
spread
to
the
hallway.
I
__7__
her
lips
(嘴唇)and
raised
my
hand
right
away.
For
once
I
knew
the
answer!
But
I
was
afraid
when
she
called
out
my
name.
Then
I
answered
her
question
__8__.
I
will
never
forget
what
happened
next.
Mrs.
Jordan
pointed
directly
at
me.
With
shining
eyes
and
a
wide
smile,
she
cried,
“THAT’S
RIGHT,
STEPHEN!”
I
was
filled
with
excitement
__9__
I
became
a
star
for
the
first
time
in
my
young
life.
Right
then
and
there
I
made
a
__10__
that
I
would
make
a
place
for
myself
in
this
world.
No
matter
how
many
difficulties
I
might
meet
in
life,
I
knew
I
could
overcome
them.
The
simple
three
words
had
completely
changed
my
young
life,
“THAT’S
RIGHT,
STEPHEN!”

四、阅读理解
It
was
a
Christmas
night.
I
was
an
unlucky
nurse
who
had
to
work
on
such
a
beautiful
festival.
When
I
was
so
tired
that
I
didn’t
want
to
work
any
longer,
three
people
came
to
my
desk
—
a
tired
woman
and
two
children.
"Are
you
all
sick?"
I
asked.
"Yes,"
the
woman
answered
and
lowered
her
head.
But
when
they
started
to
tell
their
problems,
things
became
unclear.
One
child
had
a
fever,
but
his
temperature
was
OK.
The
other
child
had
an
earache,
but
she
could
not
tell
me
which
ear
hurt.
It
seemed
that
the
mother
was
trying
to
cough.
Something
was
wrong.
But
I
only
explained
that
it
might
take
a
while
before
a
doctor
could
meet
them.
"Take
your
time,
please,"
said
the
mother.
I
checked
their
information
—
no
address.
Suddenly
I
knew,
they
were
homeless
and
the
hospital
was
warm.
The
family
stayed
together
under
the
Christmas
tree,
smiling
and
talking
with
each
other
sweetly.
Quietly,
I
went
back
to
the
nurses'
station
and
told
them
what
happened
in
the
waiting
room.
It
was
just
like
the
God
sending
us
a
gift
on
Christmas
Day.
The
nurses'
station
suddenly
came
back
to
life.
All
the
nurses
went
into
action
for
"a
Christmas
emergency(急诊)."
We
took
out
our
meals
for
our
Christmas
"sick
people".
We
also
put
oranges
and
apples
together
as
presents.
We
tried
to
give
them
a
warm
place
on
Christmas
night.
Later,
the
little
girl
kissed
me
and
said,
"Thanks
for
being
our
angels"

五、参考例文。
Doing
housework
Last
week,
our
class
made
a
survey
on
doing
housework
among
ourselves.
According
to
the
survey,
40
per
cent
of
our
classmates
often
do
some
washing
such
as
washing
clothes,
dishes
and
vegetables.
There
are
35
per
cent
students
cleaning
the
house.
They
sweep
the
floors
and
clean
the
window.
12
per
cent
students
do
some
shopping
for
their
families.
And
about
8
per
cent
of
them
do
the
cooking.
However,
there're
5
per
cent
students
hardly
doing
any
housework.
I
think
as
a
member
of
the
family,
it's
our
responsibility
to
do
housework.
We
should
learn
to
do
some
simple
housework.
Also,
it's
helpful
for
us
to
learn
some
living
skills
from
it.
