鲸鱼知多少?
鲸的体型是世界上存在的动物中最大的,它是终生生活在水中的哺乳动物,对水的依赖程度很大。鲸形状像鱼,鼻孔在头的上部,用肺呼吸。它体长可达三十米,是现在世界上最大的动物。
鯨为适应水中生活,减少阻力,它们的后肢消失,前肢变成划水的浆板。身体成为流线型,酷似鱼。因而它们的潜水能力很强,小型齿鲸可潜至100-300米的水深处停留4-5分钟,长须鲸可在水下300-500米处待上1小时，最大的齿鲸—抹香鲸能澘至干米以下,并在水中持续243175时之久。

V.阅读理解
Zhalong
is
a
nature
reserve
in
Heilongjiang
in
Northeast
China.
It
is
one
of
the
world’s
most
important
wetlands(湿地).
The
area
provides
food
and
homes
for
wildlife.
It
is
a
perfect
home
for
different
kinds
of
plants,
fishes
and
birds.
Many
birds
live
comfortably
in
Zhalong
Nature
Reserve
all
year
round,
while
some
only
stay
for
a
short
time.
There
are
many
fish
in
the
wetlands,
and
the
birds
can
easily
catch
them
for
food.
Zhalong
Nature
Reserve
is
an
important
living
area
for
the
rare(稀有的)
red-crowned
cranes(丹顶鹤).
There
are
not
many
red-crowned
cranes
in
the
world.
Some
of
them
live
in
Zhalong.
Some
people
want
to
change
the
wetlands
to
make
more
space
for
farms
and
buildings.
This
means
that
there
will
be
less
and
less
space
for
wildlife.
More
and
more
birds
are
in
danger
because
they
do
not
have
enough
living
space.
Many
of
them
died.
The
Chinese
government
wants
to
protect
these
endangered
birds,
and
they
can
be
safe
in
Zhalong.
Every
year
a
lot
of
tourists
go
to
Zhalong
to
watch
birds.
This
year
members
of
our
Birdwatching
Club
are
going
to
study
the
different
kinds
of
birds
in
Zhalong
and
the
changes
in
their
numbers.
The
study
will
begin
next
month.
We
do
a
bird
count
once
a
year.
We
are
now
inviting
secondary
school
students
to
help.
We
need
more
people
to
help
us
count
and
do
something
to
help
the
birds.
Many
people
do
not
understand
the
importance
of
the
wetlands.
We
hope
this
information
will
help
them
understand
it
and
make
them
actively
take
action
to
protect
wildlife.
( )21.What
can
we
learn
from
the
second
paragraph?
A.
All
birds
stay
in
Zhalong
Nature
Reserve
all
year
round.
B.
There
are
a
few
fish
in
the
wetlands.
C.
The
number
of
the
world’s
red-crowned
cranes
is
small.
D.
All
the
red-crowned
cranes
live
in
Zhalong
Nature
Reserve.
( )22.How
do
we
protect
the
birds
in
danger
this
year?
A.
The
Birdwatching
Club
just
does
a
bird
count
once
a
year.
B.
The
Birdwatching
Club
only
studies
different
kinds
of
birds.

Zhalong
