八.阅读理解。
Dr.
Irene
Pepperberg,
a
scientist
at
the
University
of
Arizona,
has
worked
with
Alex
for
nine—ten
years.
Teaching
Alex
to
speak
and
understand
wasn’t
easy
at
first.
He
had
to
learn
one
word
at
the
time.
Irene
and
an
assistant
(助手)
would
teach
Alex
by
showing
him
what
a
word
meant.
Irene
would
hold
up
an
object.
Saying
“What’s
this ”
Her
assistant
would
give
the
word
--"candy”,
for
example--while
Alex
watched.
Irene
would
praise
her
assistant
,
then
ask
Alex
the
name
of
the
object.
When
he
got
it
right,
Irene
would
praise
him
and
give
him
the
object
to
play
with
as
a
reward.
It
took
Alex
many
weeks
to
learn
his
first
word.
After
that,
each
new
word
became
easier
and
easier
for
him.
Why
did
Irene
spend
so
much
time
getting
a
parrot
to
talk
Scientists
like
Irene
are
interested
in
discovering
how
intelligent
animals
are
and
how
their
brains
work.
But
studying
animal
intelligence
has
always
been
difficult,
partly
because
animals
haven’t
been
able
to
communicate
clearly
with
humans.
Teaching
Alex
to
speak
words
that
he
understands
has
let
Irene
talk
to
him
directly.
She
can
ask
him
questions,
and
he
can
answer
them
in
English.
In
this
way,
Irene
is
finding
out
that
kinds
of
things
Alex’s
brain
can
do.
She
has
found
that
parrots
are
much
smarter
than
scientists
used
to
think.
(
)1．According
to
the
passage,
how
is
Alex
remarkable
(不寻常的)

A．He
can
use
the
English
language
to
answer
questions.
B．He
uses
words
in
English
instead
of
bird
calls
to
call
other
birds.
C．He
can
copy
the
pronunciations
of
more
than
100
English
words.
D．Alex
has
a
brain
that
is
much
bigger
than
those
of
other
parrots.
(
)2．How
did
Dr.
Pepperberg
teach
Alex
to
speak
with
understanding
A．She
said
the
same
word
all
day
long
so
that
Alex
could
repeat
it.
B．She
taught
Alex
a
special
sign
language.
C．She
gave
Alex
rewards
if
he
would
say
what
she
said.
D．She
gave
Alex
a
candy
every
time
he
answered
correctly.
(
)3．Why
did
Dr.
Pepperberg
teach
Alex
to
speak
with
understanding
A．She
wanted
to
prove
it
could
be
done.
B．She
wanted
to
provide
a
model
for
people
who
want
talking
birds.
C．She
wanted
to
find
out
how
many
words
parrots
could
remember.
D．She
wanted
to
find
out
what
kinds
of
things
his
brain
could
do.
(
)4．According
to
the
passage,
Alex
has
proved
that .
A．birds
are
not
the
only
animals
that
can
learn
a
language
B．parrots
are
much
cleverer
than
scientists
used
to
think
C．
birds
are
just
as
intelligent
as
humans
D．teaching
parrots
to
speak
a
human
language
isn’t
very
difficult
