五、阅读理解
Ladies
and
gentlemen,
I
have
spent
my
entire
life
either
at
the
schoolhouse,
on
the
way
to
the
schoolhouse,
or
talking
about
what
happens
in
the
schoolhouse.
Both
my
parents
and
my
grandparents
were
educators,
and
for
the
past
40
years
I’ve
done
the
same
thing.
And
so,
needless
to
say,
over
those
years
I’ve
had
a
chance
to
look
at
education
reform
from
a
lot
of
perspectives(观点).
And
we
know
why
kids
drop
out.
We
know
why
kids
don’t
learn.
It’s
either
poverty(贫困),
low
attendance
or
negative
peer
influences.
We
know
why.
But
one
of
the
things
that
we
never
discuss
or
we
rarely
discuss
is
the
value
and
importance
of
human
connection
and
relationships.
A
colleague
said
to
me
one
time,
“They
don’t
pay
me
to
like
the
kids.
They
pay
me
to
teach
a
lesson.
The
kids
should
learn
it.
I
should
teach
it.
They
should
learn
it.
Case
closed.”
Well,
I
said
to
her,
“You
know,
kids
don’t
learn
from
people
they
don’t
like.”
She
said,
“That’s
just
a
bunch
of
hooey(胡言乱语).”
And
I
said
to
her,
“Well,
your
year
is
going
to
be
long
and
difficult,
dear.”
Needless
to
say
it
was.
Teaching
and
learning
should
bring
joy.
How
powerful
would
our
world
be
if
we
had
kids
who
were
not
afraid
to
take
risks,
who
were
not
afraid
to
think,
and
who
had
a
champion
Every
child
deserves
a
champion:
an
adult
who
will
never
give
up
on
them,
who
understands
the
power
of
connection
and
insists
that
they
become
the
best
that
they
can
possibly
be.
Thank
you
so
much.（Speaker:
