Swimming
in
the
water
of
Hawaii's
Big
Island
is
a
fun
experience.
But
it
can
be
more
exciting
if
there
are
dolphins
swimming
around
and
jumping
out
of
the
_____17_____
too.
For
many
people,
it
would
be
a
wonderful
dream
to
swim
with
these
lovely
animals!
_____18_____,
this
may
not
be
good
for
dolphins.
They
may
get
_____19_____
because
of
human
interaction
(互动).
Dolphins
are
active
and
usually
_____20_____
food
at
night.
In
the
day,
they
like
to
rest
in
shallow
bays
(浅湾).
Many
people
think
the
dolphins
are
awake
during
the
day
as
they
swim.
But
when
they
sleep,
they
rest
half
of
their
brain
and
keep
_____21_____
half
awake
to
breathe,
so
they
may
be
sleeping
even
when
they're
swimming
in
the
water.
The
National
Oceanic
and
Atmospheric
Administration
(NOAA)
says
disturbing
(打扰)
the
animals
in
their
near-shore
habitat
could
_____22_____
them
to
swim
to

favorable
places,

of
attack
by
sharks
and
other
animals.
Moreover,
when

are
around,
dolphins
become
more
active.
Thus,
they
can't
get
enough
_____23_____.
"Disturbing
their
resting
behaviors
can
_____24_____
affect
their
long
term
health
and
the
health
of
the
dolphin
population,"
Ann
Garrett
of
NOAA's
National
Marine
Fisheries
Service
told
the
Associated
Press.
As
a
result,
the
NOAA
wants
to
make
rules
to
help
_____25_____
the
dolphins.
For
example,
the
agency
(机构)
may
stop
people
from
_____26_____

三、阅读理解-阅读n选n（共2小题；共30分）
阅读短文，根据短文内容，从短文后的五个选项中选出能填入空白处的最佳选项。每个选项只能用一次。
Since
the
great
success
of
cloning
the
sheep
Dolly,
the
cloning
of
human
beings
is
no
longer
a
fictional
story
but
can
be
proved
to
be
medically
possible.
_____27_____
I
just
want
to
say:
"No!
Never!"
_____28_____
For
example,
they
insist
that
if
we
could
clone
a
new
Einstein,
we
would
make
more
progress
on
physics,
and
if
we
could
get
a
new
Shakespeare,
we
would
enjoy
more
profound
classic
literary
works
and…
But
how
can
we
guarantee
that
another
Hitler
could
not
be
brought
back
to
life
"thanks
to"
cloning?
Moreover,
can
we
give
birth
to
a
baby
who
exactly
shares
your
grand
grandpa's
genes?
We
could
be
confused
by
that
relationship
or
kinship.
_____29_____
Some
scientists
believe
that
we
can
get
the
organs
we
need
to
save
people's
life
from
the
cloned
counterpart.
But
is
it
unfair
to
them?
Even
if
they
are
not
the
creatures
of
nature
but
of
technology,
they
are
a
kind
of
life.
_____30_____
I
do
not
suppose
this
action
is
humane.
_____31_____
it
is
another
violation
of
the
natural
law.
Life
should
be
a
circle
from
birth
to
death
and
then
re-birth
and
re-death.
Every
round
of
change
can
breed
more
varieties
of
genes.
Thereby
our
human
species
can
live
rather
than
copying
ourselves
repeatedly,
which
I
would
lead
to
the
final
retrogression
(退化)
of
human
species.
27.
A.I
do
not
think
we
can
be
granted
the
right
to
kill
them
and
take
out
the
organs
for
our
use.
B.If
we
can
always
replace
our
old
organs
with
new
ones,
we
will
predictably
never
die,
C.Thus,
the
problem
unavoidable
arises,
should
we
permit
human
cloning?
D.And
in
that
case,
we
would
find
ourselves
lost
in
an
embarrassing
and
disorderly
situation.
E.Some
people
maintain
that
it
can
save
talents.

In
the
middle
of
my
home
country
there
are
very
large
places.
They
are
hot
and
dry
land
called
deserts.
_____32_____
Families
live
a
long
way
from
other
people.
Sometimes
they
are
the
only
people
for
thousands
of
kilometres.
_____33_____
About
65
years
ago
these
people
found
that
using
strong
radios
was
a
possible
way
for
families
living
far
away
to
communicate
with
each
other.
They
decided
they
could
use
the
radios
for
school.
In
this
way,
children
could
talk
to
each
other
like
at
school.
_____34_____
The
children
each
spent
about
30
minutes
a
day
on
the
radio.
They
talked
to
their
teacher
about
their
work
and
difficulties.
The
teacher
designed
some
exercises
and
tasks
based
on
what
they
learned
and
posted
them
to
the
children.
After
finishing
their
work,
the
children
sent
it
back
to
their
teacher
to
mark.
_____35_____
He
tried
to
visit
each
child
twice
each
year.
This
was
sometimes
difficult.
The
journey
was
very
long
and
could
be
dangerous.
In
addition,
the
school
held
camps
once
a
year.
The
children
could
all
meet
each
other
and
shared
their
learning
experience.
_____36_____
The
government
provides
families
with
computers
so
that
the
children
can
use
the
Internet
to
talk
to
their
teachers
and
classmates
by
e-mail
now.
The
teachers
enjoy
their
work
very
much
because
they
get
to
know
the
children
and
their
families
very
well.
It
is
an
interesting
way
to
learn,
don't
you
think?
