完形填空
Many
of
the
most
(?http:?/??/?www.21cnjy.com?)
memorable
ad
campaigns
around
tend
to
be
funny.
Advertisers
use
this
strategy
to
attract
customers
to
their
product.
Audiences
like
to
be1
.
People
will
pay
more
attention
to
a
humorous
commercial
than
a
2
or
serious
one,
opening
themselves
up
to
be
3
.
The
key
to
funny
advertising
is
assuring
the
humor
is
appropriate
to
both
product
and
customer.
The
balance
between
funny
and
obnoxious
can
often
be
delicate;
and
a
marketer
must
be
certain
the
positive
effects
outweigh
the
negative
before
an
advertisement
can
be
introduced.
The
best
products
(?http:?/??/?www.21cnjy.com?)
to
sell
using
humor
tend
to
be
those
that
consumers
have
to
think
the
least
about.
Products
that
are
relatively
inexpensive,
and
often4
,
can
be
represented
without
providing
a
lot
of
facts,
and
that's
where
there's
room
for
humor.
Candy,
food,
alcohol,
5and
toys/entertainment
related
products
have
proven
to
benefit
6
from
humor
in
their
campaigns.
Another
point
(?http:?/??/?www.21cnjy.com?)to
consider
when
using
humor
in
advertising
is
that
different
things
are
funny
to
different
people.
A
commercial
that
may
leave
one
person
gripping
their
sides
from
laughter
may
leave
a
7
in
another's
mouth.
The
target
8
must
always
be
considered.
What's
funny
in
a
client
presentation
may
not
be
funny
on
an
airplane,
at
a
country
club
or
in
a
hospital.
Humor
in
advertis
(?http:?/??/?www.21cnjy.com?)ing
tends
to
improve9
,
but
does
not
improve
product
recall,
message
credibility,
or
10
.
In
other
words,
consumers
may
be
familiar
with
and
have
good
feelings
towards
the
product,
but
their
purchasing
decisions
will
probably
not
be
11
.
One
of
the
major
keys
to
a
successful
humorous
campaign
is12
,
once
a
commercial
starts
to
wear
out
there's
no
13
it
without
some
variation
on
the
concept.
Humorous
campaigns
are
often
14
because
they
have
to
be
constantly
changed.
Advertisers
must
remember
that
while
making
the
customer
laugh,
they
have
to
keep
things
interesting,
because

完形填空
Many
of
the
most
mem
(?http:?/??/?www.21cnjy.com?)orable
ad
campaigns
around
tend
to
be
funny.
Advertisers
use
this
strategy
to
attract
customers
to
their
product.
Audiences
like
to
be1
.
People
will
pay
more
attention
to
a
humorous
commercial
than
a
2
or
serious
one,
opening
themselves
up
to
be
3
.
The
key
to
funny
advertising
is
assuring
the
humor
is
appropriate
to
both
product
and
customer.
The
balance
between
funny
and
obnoxious
can
often
be
delicate;
and
a
marketer
must
be
certain
the
positive
effects
outweigh
the
negative
before
an
advertisement
can
be
introduced.
The
best
products
(?http:?/??/?www.21cnjy.com?)to
sell
using
humor
tend
to
be
those
that
consumers
have
to
think
the
least
about.
Products
that
are
relatively
inexpensive,
and
often4
,
can
be
represented
without
providing
a
lot
of
facts,
and
that's
where
there's
room
for
humor.
Candy,
food,
alcohol,
5and
toys/entertainment
related
products
have
proven
to
benefit
6
from
humor
in
their
campaigns.
2·1·c·n·j·y
Another
point
to
c
(?http:?/??/?www.21cnjy.com?)onsider
when
using
humor
in
advertising
is
that
different
things
are
funny
to
different
people.
A
commercial
that
may
leave
one
person
gripping
their
sides
from
laughter
may
leave
a
7
in
another's
mouth.
The
target
8
must
always
be
considered.
What's
funny
in
a
client
presentation
may
not
be
funny
on
an
airplane,
at
a
country
club
or
in
a
hospital.
Humor
in
adverti
(?http:?/??/?www.21cnjy.com?)sing
tends
to
improve9
,
but
does
not
improve
product
recall,
message
credibility,
or
10
.
In
other
words,
consumers
may
be
familiar
with
and
have
good
feelings
towards
the
product,
but
their
purchasing
decisions
will
probably
not
be
11
.
One
of
the
major
keys
to
a
successful
humorous
campaign
is12
,
once
a
commercial
starts
to
wear
out
there's
no
13
it
without
some
variation
on
the
concept.
Humorous
campaigns
are
often
14
because
they
have
to
be
constantly
changed.
Advertisers
must
remember
that
while
making
the
customer
laugh,
they
have
to
keep
things
