Neither
Pine
nor
Apple
in
Pineapple
Have
you
ever
asked
yourself
(1)
why
people
often
have
trouble
learning
English?
I
hadn'
t,
until
one
day
my
five-year-old
son
asked
me
(2)
whether
there
was
ham
in
a
hamburger.
There
isn'
t.
This
made
me
realize
(3)
that
there'
s
no
egg
in
eggplant
either.
(4)
Neither
is
there
pine
nor
apple
in
pineapple.
This
got
me
thinking
(5)
how
English
can
be
a
crazy
language
to
learn.
For
example,
in
our
free
time
we
can
sculpt
a
sculpture
and
paint
a
painting,
but
we
take
a
photo.
And
(6)
when
we
are
traveling
we
say
that
we
are
in
the
car
or
the
taxi,
but
on
the
train
or
bus!
(7)
While
we'
re
doing
all
this
traveling,
we
can
get
seasick
at
sea,
airsick
in
the
air
and
carsick
in
a
car,
but
we
don'
t
get
homesick
(8)
when
we
get
back
home.
And
speaking
of
home,
why
aren'
t
homework
and
housework
the
same
thing?
(9)
If
"hard"
is
the
opposite
of
"soft"
，
why
are
"hardly"
and
softly
not
an
opposing
pair?
(10)
If
harmless
actions
are
the
opposite
of
harmful
actions,
why
are
shameless
and
shameful
behaviors
the
same?
(11)
When
we
look
out
of
the
window
and
see
rain
or
snow,
we
can
say
"it'
s
raining"
or
"it'
s
snowing"
.
But
(12)
when
we
see
sunshine,
we
can'
t
say
"it'
s
sunshining"
.
Even
the
smallest
words
can
be
confusing.
(13)
When
you
see
the
capitalized
"WHO"
in
a
medical
report,
do
you
read
it
as
the
"who"
in
"Who'
s
that?
"
What
about
"IT"
and
"US"
?
You
also
have
to
wonder
at
the
unique
madness
of
a
language
(14)
in
which
a
house
can
burn
up
as
it
burns
down,
(15)
in
which
you
fill
in
a
form
by
filling
it
out,
and
(16)
in
which
an
alarm
is
only
heard
once
it
goes
off!
English
was
invented
by
people,
not
computers,
and
it
reflects
the
creativity
of
the
human
race.
(17)
That
is
why
when
the
stars
are
out,
they
are
visible
,
but
when
the
lights
are
out,
they
are
invisible.
And
that
is
why
when
I
wind
up
my
watch,
it
starts,
but
when
I
wind
up
this
passage,
it
ends.

Neither
is
there
pine
nor
apple
in
pineapple.（教材P14）菠萝中既没有松树也没有苹果。
【分析】
本句中neither...nor...意为“既不……也不……”，其含义是否定的，可连接任意两个并列的成分。
【总结】
neither...nor...的用法：
(1)
neither...nor...连接两个主语时，谓语动词的单复数应和临近的主语一致，遵循“就近原则”。
(2)
neither可以单独作主语，表示“两者中没有一个”。
(3)
表示“一个人没有做某事，另一个人也没做同一类事”时，可用neither或nor引起的部分倒装句进行简略回答，其结构为：Neither/
Nor＋助动词/
情态动词/
be动词＋主语。
·Neither
