新题型
For
more
than
twenty
( http: / / www.21cnjy.com )
years
scientists
have
been
seeking
to
understand
the
mystery
of
the‘‘
sixth
sense
"of
direction．By
trying
out
ideas
and
solving
problems
one
by
one，they
are
now
getting
closer
to
one
answer．
One
funny
idea
is
that
animals
might
have
a
built-in
compass(指南针)．
Our
earth
itself
is
a
( http: / / www.21cnjy.com )
big
magnet(磁体)．So
a
little
magnetic
needle
that
swings
freely
lines
itself
with
the
big
earth
magnet
to
point
north
and
south．When
people
discovered
that
idea
about
a
thousand
years
ago
and
invented
the
compass，it
allowed
sailors
to
navigate
(航海)on
ocean
voyages,
even
under
cloudy
skies.
Actually
the
idea
of
( http: / / www.21cnjy.com )the
living
compass
came
just
from
observing
animals
in
nature．
Many
birds
m
( http: / / www.21cnjy.com )igrate
twice
a
year
between
their
summer
homes
and
winter
homes．Some
of
them
fly
for
thousands
of
kilometers
and
mostly
at
night．Experiments
have
shown
that
some
birds
can
recognize
star
patterns．But
they
can
keep
on
course
even
under
cloudy
skies．How
can
they
do
that
A
common
bird
that
( http: / / www.21cnjy.com )does
not
migrate
but
is
great
at
finding
its
way
home
is
the
homing
pigeon．Not
all
pigeons
can
find
their
way
home．Those
that
can
are
very
good
at
it，and
they
have
been
widely
studied．
One
interesting
e
( http: / / www.21cnjy.com )xperiment
was
to
attach
little
magnets
to
the
birds’
heads
to
block
their
magnetic
sense—just
as
a
loud
radio
can
keep
you
from
hearing
a
call
to
dinner．On
sunny
days,
that
did
not
fool
the
pigeons．Evidently
they
can
use
the
sun
to
tell
which
way
they
are
going．But
on
cloudy
days，the
pigeons
with
magnets
could
not
find
their
way．It
was
as
if
the
magnets
had
blocked
their
magnetic
sense．
Similar
experimen
( http: / / www.21cnjy.com )ts
with
the
same
kind
of
results
were
done
with
honeybees．These
insects
also
seem
to
have
a
special
sense
of
direction．
In
spite
of
the
experi
( http: / / www.21cnjy.com )ments，the
idea
of
an
animal
compass
seemed
pretty
extraordinary．How
would
an
animal
get
the
magnetic
stuff
for
a
compass？
An
answer
cam
( http: / / www.21cnjy.com )e
from
an
unexpected
source．A
scientist
was
studying
bacteria
that
live
in
the
mud
of
ponds
and
marshes．He
found
accidentally
little
rod-like
bacteria
that
all
swam
together
in
one
direction—north．
Further
stud
( http: / / www.21cnjy.com )y
showed
that
each
little
bacterium
had
a
chain
of
dense
particles
inside，which
proved
magnetic．The
bacteria
had
made
themselves
into
little
magnets
that
could
line
up
with
the
earth’s
magnet．
The
big
news
was
th
( http: / / www.21cnjy.com )at
a
living
thing，even
a
simple
bacterium，can
make
magnetite．That
led
to
a
search
to
see
whether
animals
might
have
it..
By
using
a
special
instrument
called
magnetometer，scientists
were
able
to
find
magnetite
in
bees
and
birds，and
even
in
fish．In
each
animal，except
for
the
bee．the
magnetic
stuff
was
always
in
or
closer
to
the
brain．
Thus．the
idea
of
a
built—in
animal
compass
began
to
seem
reasonable

and
broke

Eyes
can
speak
Much
meaning
can
( http: / / www.21cnjy.com )be
conveyed,
clearly,

so
it
is

I
( http: / / www.21cnjy.com )n
a
bus
you
may
look
at
a
stranger,
but
not
for
too
long.
And
if
he
senses
that
you
are
staring
at
him,
he
may
feel
uncomfortable.
The
same
is
true
( http: / / www.21cnjy.com )in
our
daily
life.
If
you
are
stared
at
for
more
than
necessary,
you
will
look
at
yourself
up
and
down
to
see
if
there
is
anything
wrong
with
you.
37
Eyes
do
speak,
right
Looking
too
long
( http: / / www.21cnjy.com )
at
someone
may
seem
to
be
rude
and
aggressive.
38
If
a
man
stares
at
a
woman
for
more
than
10
seconds
and
refuses
to
look
away
from
her,
his
intentions
are
obvious.
He
wishes
to
attract
her
attention
and
let
her
know
that
he
is
admiring
her.
However,
when
two
( http: / / www.21cnjy.com )
people
are
engaged
in
a
conversation,
the
speaker
will
only
look
into
the
listener’s
eyes
from
time
to
time
to
make
sure
that
the
listener
does
pay
attention
to
what
the
former
is
speaking.
39
If
a
speaker
looks
at
you
continuously
when
speaking
as
if
trying
to
control
you,
you
will
feel
awkward.
A
poor
liar
usually
exposes
himself
by
looking
too
long
at
the
victim.
He
wrongly
believes
that
looking
straight
in
the
eye
is
a
sign
of
honest
communication.
40
Actually,
eye
( http: / / www.21cnjy.com )
contact
should
be
made
based
on
specific
relationships
and
situations.
A.
On
the
contrary,
it
will
give
him
away.
B.
Do
