冠词是用在名词前面,帮助说明名词所指的人或事物,是泛指还是特指的词。冠词是一种虚词。
冠词分不定冠词(The
Indefinite
Article)和定冠词(The
Definite
Article)a,
an是不定冠词,the是定冠词。
an,
a是不定冠词,仅用在单数可数名词前面,表示“一”的意义,但不强调数目观念。a用在以辅音(指辅音音素)开头的词前,
an用在以元音(指元素音素)开头的词前,如:
a
boy
an
hour
a
history
class
an
island
a
university
an
elephant
a
hero
an
old
man
不定冠词的用法:
1.
表示人或事物的某一类
A
steel
worker
makes
steel.
A
plane
is
a
machine
that
can
fly.
2.
表示某一类人或事物中的任何一个。
This
is
an
apple.
His
father
is
a
teacher.
3.
泛指某人或某物,但不具体说明何人何物。
A
comrade
is
waiting
for
you
downstairs.
I
met
an
old
man
on
my
way
to
school.
4.
表示“一个”的意思
He
will
be
back
in
a
day
or
two.
He
tried
to
send
a
picture
of
a
face.
5.
有时也表示“每”的意思
We
have
three
meals
a
day.
我们一日三岁.
He
walks
ten
miles
an
hour.
他一小时走10英里。
We
have
six
classes
a
day.
我们一天上六节课。
He
drives
the
car
at
thirty
miles
an
hour.
如果把不定冠词后的名词变为复数,只把不定冠词去掉还不行,还得补上一个数词或不定代词(some,
any)
The
plan
will
be
ready
in
a
few
days.
这是因为“一个”或“某个”变为复数时,就成为“几个”或“某几个”的缘故。
