大熊猫最奇特的一点
是新生儿在出生时相当的不成熟，体重仅是它母亲体重的0.1%，平均为145克左右，
约为成年的千分之一。照顾孩子是一项非常艰巨的任务，通常历时18个月，有时长达两年，直到她的下一个孩子出生。

阅读理解
Thousands
of
years
ago,
Shennong,
who
had
an
ox
(牛)
head
and
human
body,
lived
in
the
south
of
ancient
China.
Seeing
that
local
people
were
suffering
from
disease,
he
built
ladders
(梯子)
and
houses
on
a
high
mountain
to
store
medical
plants.
To
remember
him,
people
named
the
place
Shennongjia.
The
story
makes
Shennongjia
in
Hubei
an
inviting
place
for
tourists.
Traveling
there
is
a
quite
different
experience,
as
you
can
see
sceneries
(风景)
of
the
four
seasons
from
different
height.
“When
the
bottom
of
the
mountain
is
summer,
the
top
is
spring
and
while
the
foothill
is
autumn,
the
top
is
covered
with
ice,”
local
people
say
of
the
special
climate
of
Shennongjia.
Shennongjia
is
also
home
to
5,000
kinds
of
animals
and
plants.
Many
rare
animals
live
there,
such
as
the
golden
monkey
and
the
Asian
black
bear.
One
interesting
thing
about
Shennongjia
is
its
story
of
wild
men.
Some
people
said
that
they
saw
big
foot
marks.
Yet
so
far,
scientists
haven’t
proved
(证实)
it
is
true
and
some
say
they
are
just
bears.
The
beautiful
place
has
recently
received
a
new
title.
It
was
added
to
United
Nations
World
Heritage
(遗产)
list
as
a
natural
site.
China
now
has
50
world
heritage
sites,
only
less
than
Italy
in
the
world.
