课时作业(十九)Ⅰ.阅读理解[2023·新课标I卷]On
March
7,
1907,
the
English
statistician
Francis
Galton
published
a
paper
which
illustrated
what
has
come
to
be
known
as
the
“wisdom
of
crowds”
effect.
The
experiment
of
estimation
he
conducted
showed
that
in
some
cases,
the
average
of
a
large
number
of
independent
estimates
could
be
quite
accurate.This
effect
capitalizes
on
the
fact
that
when
people
make
errors,
those
errors
aren’t
always
the
same.
Some
people
will
tend
to
overestimate,
and
some
to
underestimate.
When
enough
of
these
errors
are
averaged
together,
they
cancel
each
other
out,
resulting
in
a
more
accurate
estimate.
If
people
are
similar
and
tend
to
make
the
same
errors,
then
their
errors
won’t
cancel
each
other
out.
In
more
technical
terms,
the
wisdom
of
crowds
requires
that
people’s
estimates
be
independent.
If
for
whatever
reasons,
people’s
errors
become
correlated
or
dependent,
the
accuracy
of
the
estimate
will
go
down.But
a
new
study
led
by
Joaquin
Navajas
offered
an
interesting
twist(转折)
on
this
classic
phenomenon.
The
key
finding
of
the
study
was
that
when
crowds
were
further
divided
into
smaller
groups
that
were
allowed
to
have
a
discussion,
the
averages
from
these
groups
were
more
accurate
than
those
from
an
equal
number
of
independent
individuals.
For
instance,
the
average
obtained
from
the
estimates
of
four
discussion
groups
of
five
was
significantly
more
accurate
than
the
average
obtained
from
20
independent
individuals.In
a
follow-up
study
with
100
university
students,
the
researchers
tried
to
get
a
better
sense
of
what
the
group
members
actually
did
in
their
discussion.
Did
they
tend
to
go
with
those
most
confident
about
their
estimates?
Did
they
follow
those
least
willing
to
change
their
minds?
This
happened
some
of
the
time,
but
it
wasn’t
the
dominant
response.
Most
frequently,
the
groups
reported
that
they
“shared
arguments
and
reasoned
together”.
Somehow,
these
arguments
and
reasoning
resulted
in
a
global
reduction
in
error.
Although
the
studies
led
by
Navajas
have
limitations
and
many
questions
remain,
the
potential
implications
for
group
discussion
and
decision-making
are
enormous.(

In
order
for
a
business
to
survive
in
today’s
world,
it
is
important
that
we
regularly
review
what
we
are
doing
and
how
we
are
doing
it.By
considering
new
ideas
and
new
ways
of
doing
things,we
can
improve
our
products
or
services,increase
sales,reduce
costs
and
make
our
processes
more
effective
and
efficient.

BUsing
the
latest
technology
to
improve
your
products
or
services.When
we
think
of
innovation,we
often
think
of
new
technologies.While
they
might
be
impressive,
we
should
not
use
new
technologies
just
because
they
are
available.

Companies
that
produce
cars,
household
appliances,
etc.often
have
a
large
R&D(研发)
department
to
work
on
making
their
products
better.G

By
listening
to
customer
feedback,
we
can
get
their
opinions
on
how
we
are
doing
and
find
out
about
what
it
is
that
they
want.We
also
need
to
be
aware
of
changes
in
customer
demands
and
keep
up
with
the
times.DOffering
a
new
product
or
service
to
reach
new
customers.

Innovation
sometimes
means
developing
a
new
product
that
targets
a
different
group
of
customers.Although
video
games
were
often
played
by
boys,in
2006,a
video
games
giant
introduced
a
new
game,successfully
targeting
girls
and
older
customers.F

By
looking
at
the
changes
to
the
customer’s
lifestyle
and
needs,we
sometimes
realize
that
there
might
be
better
ways
to
serve
them.Customers
who
do
not
have
a
lot
of
time
might
prefer
to
have
their
food
or
their
shopping
delivered
to
their
homes,or
they
like
to
do
their
banking
