(?http:?/??/?www.21cnjy.com?)去式；is

9.句意：晚饭后，他教你弹钢琴。

九、阅读理解
For
the
British,
(?http:?/??/?www.21cnjy.com?)
home
is
a
private
place
in
which
he
or
she
goes
to
hide
away
from
the
troubles
of
life.
It
is
very
seldom
that
one
would
be
invited
to
a
British
person’s
home.
It
is
rude
to
knock
on
a
person’s
door
if
you
are
not
invited.
If
you
are
invited,
don’t
ask
to
see
more
than
the
downstairs
that
your
British
host
invites
you
into.
Never
ask
how
much
the
house
or
any
of
the
items
in
it
cost.
【版权所有：21教育】
To
the
America

They
may
be
delighted
to
give
you
a
full
tour
of
their

They
may
also
be
pleased
when
you
show
your

Both
British

(?http:?/??/?www.21cnjy.com?)American
people
will
engage
in
quite
a
bit
of
chat
and
a
drink
or
two
before
the
meal
is
served.
After
the
first
mouthful,
you
should
say
how
delicious
the
food
is
and
ask
something
about
it.
Remember,
never
eat
with
your
mouth
open
and
make
very
little
noise
while
eating.
It
would
be
nice
of
you
to
help
your
host
in
any
way.
Maybe
offer
to
pour
some
drinks
or
clear
up
after
the
meal.

For
the
British,
home
(?http:?/??/?www.21cnjy.com?)
is
a
private
place
in
which
he
or
she
goes
to
hide
away
from
the
troubles
of
life.
It
is
very
seldom
that
one
would
be
invited
to
a
British
person’s
home.
It
is
rude
to
knock
on
a
person’s
door
if
you
are
not
invited.
If
you
are
invited,
don’t
ask
to
see
more
than
the
downstairs
that
your
British
host
invites
you
into.
Never
ask
how
much
the
house
or
any
of
the
items
in
it
cost.

people
will
engage
in
quite
a
bit
of
chat

a
drink
or
two
before
the
meal
is
served.
After
the
first
mouthful,
you
should
say

is
and
ask
something
about
it.
Remember,
never
eat
with
your

open
