Dear
Grandpa,
How
are
you?
I'm
writing
to
say
a
big
“thank
you”
for
my
birthday
gift.
I
really
love
the
MP6
and
I
listen
to
it
every
day
when
I
walk
to
work.
Everything
here
is
going
well.
I
started
my
new
job
last
week
and
I
like
it
very
much.
These
days
I'm
living
with
some
friends
in
an
apartment
(公寓)
in
the
city
center,
but
it's
very
expensive,
so
I'm
trying
to
find
another
place.
I
will
look
at
an
apartment
tomorrow,
ten
kilometers
outside
the
city.
What
other
news
(消息)
is
here?
Well,
I'm
learning
to
drive
these
days.
Mom
told
me
on
the
phone
last
night
that
you
bought
a
new
car.
Is
the
car
cool?
I
saw
Mom
and
Dad
last
week.
I
traveled
(旅行)
down
Bridgton
on
Friday
night
and
stayed
for
the
weekend.
Mom's
fine
but
Dad
isn't
very
happy.
He
doesn't
like
his
job.
I
think
he
should
try
to
find
a
new
one.
I
have
to
stop
now
because
Joe
is
calling
me.
We
will
go
to
Mary's
party
tonight.
Take
care,
and
thank
you
again.

Yours,

In
the
past，women
spent
hours
a
day
in
doing
housework
but
men
did
less.
But
a
survey(调查)
in
the
UK
shows
that
now
men
do
housework
as
much
as
women
in
40%
of
the
families.(A)Now_men_do_more_housework_than_before.
And
in
about
half
of
the
families
women
and
men
do
housework
together.
The
survey
also
shows
that
2/3
of
women
will
be
happy
when
men
help
with
housework，although
they
often
end
up
doing
the
work
themselves．Some
of
them
said，“Men
just
don't
care
as
much
as
women.(B)或许是因为男人不知道怎么做家务。”
From
another
survey
in
Canada
we
can
find
that
women
at
the
age
of
20～30
spend
more
time
on
their
work
and
less
time
on
housework.
根据短文内容，完成下面的小题。
1．In
the
past，____________
spent
less
time
on
housework.
2．Now
women
and
men
do
housework
together
in
about
________percent
of
the
families.
3．The
underlined
word
“themselves”
refers(指)
to
“_________”
in
Chinese.
