二、完形填空（本题共
10
分，每小题
1
分）
Sometimes
the
most
difficult
thing
about
feelings
is
sharing
them
with
others.
Sharing
your
feelings
21
you
when
your
feelings
are
good
and
when
they
aren’t
so
good.
22
you
can
share
them
with
anyone,
you
have
to
figure
out
(
了
解
)
your
feelings.
Then
you
can
say,
“I
feel
23
when
my
friend
doesn’t
play
with
me.”
or
“I
feel
angry
when
my
brother
always
wins
at
baseball.”
This
can
help
you
understand
your
own
feelings.
It
also
gives
the
person
you’re
talking
with
24
information
about
what
makes
you
angry.
It
can
be
really
25
not
to
tell
anyone
that
you’re
feeling
bad,
worried
or
angry.
If
you
keep
the
feelings
locked
inside,
it
can
even
make
you
26
sick!
But
if
you
talk
with
someone
27
your
mom
or
dad,
you
will
always
start
to
feel
better.
Now
you’re
not
all
alone
(独自的)
with
your
problems
or
worries.
What
if
a
kid
doesn’t
want
to
talk
with
mom
or
dad?
Then
find
28
person,
like
a
relative
(亲戚)
or
a
teacher
at
school.
If
you
think
you’ll
have
trouble
saying
what’s
on
your
mind,
29
on
a
piece
of
paper.
You
don’t
have
to
share
every
feeling
you
have,
but
it
is
important
to
share
feelings
when
you
need
help.
You
don’t
have
to
solve
(
解
决
)
every
problem
on
your
own.
30
you
need
help.
Talking
about
your
feelings
can
be
the
first
step.

(B)
Long
long
ago,
a
kind
farmer
with
the
name
of
Fred
lived
in
a
small
old
house
happily
together
with
his
gentle
wife,
Doris,
who
couldn’t
see
anything
at
the
age
of
five.
One
cold
winter
night,
the
Luck
Fairy（精灵）visited
them
while
they
were
eating
some
bread
in
the
dark.
“You’re
so
kind,
so
I’d
like
to
give
you
a
wish.”
said
the
Luck
Fairy.
“A
wish?”
Fred
and
Doris
asked,
standing
hand
in
hand
and
smiling
at
each
other.
Then
Fred
answered,
“Thanks,
Luck
Fairy.
We’re
living
a
happy
life.”
“We
are
no
longer
young,
but
we
still
work
in
the
field
from
morning
to
night
every
day.
We
enjoy
ourselves,”
said
Doris.
“You
work
very
hard
but
you
make
so
little
money.
Would
you
like
some
gold
coins
to
buy
a
nice
house?”
asked
the
Luck
Fairy.
“Oh
no,
my
dear
Luck
Fairy.
We
love
our
small
old
house.
We
have
lived
here
for
a
long
time,”
answered
Fred,
without
a
moment’s
hesitation（犹豫）.
“We
are
happy
to
work
and
live
together
all
the
time.
That’s
enough,”
Doris
agreed.
The
couple（
夫妇）
were
quite
different
from
other
people
the
Luck
Fairy
had
ever
met.
She
thanked
them
very
much.
She
disappeared,
saying,
“I
wish
you
a
happy
life
forever.”
Many
years
later,
the
couple
lived
happily
as
usual.
It
seemed
to
others
that
they
were
the
happiest
in
the
world.
Satisfaction
（
满
足
）
is
a
kind
of
feeling
that
needs
to
be
from
inside.
If
you
enjoy
the
satisfaction
from
the
simple（简单的）life,
good
luck
will
follow
you.

The
most
popular
newspapers
are
the
“tabloids”.They
usually
have
lots
of
big
pictures
and
the
articles（文章）are
not
very
long.
Tabloid
papers
do
not
have
many
serious
articles,
but
they
have
lots
of
stories
about
famous
people
and
the
royal（皇室的）family.
They
also
have
big
sports
reports
and
a
lot
of
information
about
TV
programs.
The
two
best-selling
tabloid
newspapers
are
The
Sun
and
The
Mirror.
Another
tabloid
is
The
Daily
Mail,
more
serious
than
the
other
two
tabloids.There
are
four
main
“quality”papers.
They
are
much
bigger
and
wider
than
the
tabloids
and
they
also
have
longer
and
more
serious
news
articles
with
fewer
pictures.
Quality
newspapers
have
fewer
readers.
The
oldest
and
most
famous
quality
newspaper
is
The
Times,
but
the
best
selling
ones
nowadays
are
The
Telegraph
and
The
Guardian.
Finally,
there
is
The
Financial
Times,
now
the
most
important
international
business
newspaper.
The
two
kinds
of
newspaper
are
an
interesting
part
of
British
culture.
The
“quality”
papers
are
large
and
not
easy
for
reading.
For
many
years,
people
have
been
wondering
why
they
refuse
to
change
their
size.
However,
many
other
people
like
the
size
of
the
“quality”
papers
because
it
shows
that
they
are
reading
a
serious
paper.

A
good
memory(

is
a
great
help
in
61
a
language.
Everybody
learns
his
language
by
remembering
what
he
hears
when
he
is
a
small
child,
and
some
children
like
boys
and
girls
who
live
in
other
62
with
their
parents
seem
to
learn
two
languages
almost
as
63
as
one.
In
school
it
is
not
easy
to
learn
a

language
because
the
pupils

(B)
Recently,
Chongqing
Three
Gorges
University
has
held
an
activity
named“
Cell
Phone
Ninja”(
手机忍者).
They
would
like
their
students
not
to
use
cell
phones
for
21
days.
It
is
really
a
challenge
for
most
students.
The
activity
started
on
April
12.
Each
student
who
volunteered
to
take
part
in
this
activity
got
a
bracelet(手环).
If
the
students
did
not
use
their
cell
phones,
there
would
be
a
photo
on
the
screen
of
the
bracelet
to
show
that.
If
they
used
their
cell
phones,
a
different
photo
would
appear
on
the
screen
of
the
bracelet.
After
the
last
class
of
each
day,
the
students
sent
the
photos
to
the
school's
public
We
Chat.
More
than
800
students
wished
to
take
part
in
this
test,
and
400
were
chosen.
After
seven
days,
only
103
students
remained.
The
test
was
set
for
21
days
because
some
scientists
believe
that
21
days
is
long
enough
to
help
form
a
habit.
According
to
the
teachers
in
the
university,
the
activity
was
not
a
contest.
It
depended
on
students
themselves
to
make
the
decision.
The
teachers
hoped
their
students
could
form
better
study
habits
through
activities
like
this
one.
(C)
Everyone
knows
there’s
not
enough
land
in
Hong
Kong.
If
you
go
there
by
air,
you
will
arrive
at
Kai
Tak
Airport.
This
was
built
out
into
the
sea.
It
is
in
the
part
of
Hong
Kong
called
Kowloon.
Kowloon（九龙）
is
one
of
the
two
big
cities
in
Hong
Kong.
The
other
city
is
Hong
Kong
itself.
It
is
on
island.
You
can
get
there
by
ship
or
through
a
tunnel(隧道)
under
the
sea.
Much
of
Hong
Kong
is
farmland
and
mountains.
The
population
（
人
口
）
of
Hong
Kong
is
more
than
six
million.
Chinese
and
English
are
spoken
by
many
people
there.
Clothes,
computers,
radios,
televisions
are
made
in
Hong
Kong.
You
can
buy
all
kinds
of
things,
like
watches
and
computers.
Hong
Kong
is
also
a
beautiful
city.
It
is
a
good
place
for
traveling.
You
can
see
people
from
all
over
the
world
every
year.
You
can
watch
dog-racing
and
motor-racing.
When
you
are
hot
and
tired,
you
may
rest
in
the
small
cool
gardens.
There
are
also
a
lot
of
high
buildings
to
live
in.
If
you
enjoy
many
kinds
of
cooking,
you
can
find
a
good
place
for
Chinese
food,
for
example,
fish,
meat
and
vegetables.
