二、完型填空
Life
is
short,
so
you
have
to
make
the
most
of
it.
Has
anybody
ever
told
you
that?
Maybe
they
just
said
‘‘YOLO”
to
you
instead.
It
16
“You
Only
Live
Once”,
and
is
a
very
popular
saying
on
social
media.
Having
a
YOLO
attitude
means
that
you
make
the
17
of
every
day.
It
means
you
should
enjoy
your
life
18
you
only
get
one.
Someone
who
has
a
YOLO
attitude
is
always
open
to
doing
new
and
fun
activities.
Now,
thanks
to
a
US
study,
YOLO
might
be
more
than
just
a
popular
19
.
The
study
found
it
might
be
20
to
have
a
YOLO
attitude!
A
research
team
did
an
experiment
with
two
groups
of
students
21
different
US
universities.
One
group
pretended（假装）they
only
had
30
days
left
before
moving
to
a
new
city.
They
did
lots
of
activities
and
22
time
with
people
they
loved.
In
other
words,
they
had
a
YOLO
lifestyle.
Another
group
continued
to
live
23
normal
lives.
At
the
end
of
the
experiment
the
students
did
a
survey
to
24
how
happy
they
were.
It
showed
that
the
first
group
was
much
happier.
“The
study
shows
that
being
and
making
close
friendships
are
important
to
25
life,”
the
research
group
told
The
Washington
Post.
However,
they
also
called
on
others
to
do
experiments
with
different
groups
of
people
and
see
if
their
results
were
similar.
16．A．stands
for
B．waits
for
C．thinks
of
D．points
at
17．A．worst
B．most
C．least
D．farthest
18．A．when

C．because

C．your

24．A．put
out
B．find
out

out
D．give
out
25．A．lose
B．save
C．enjoy
D．kill
三、阅读理解
Have
you
ever
wondered
how
we
know
the
things
that
we
know?
How
do
we
know,
for
example,
that
the
stars
are
really
huge
balls
of
fire
like
the
Sun
and
very
far
away?
And
how
do
we
know
that
the
Earth
is
a
smaller
ball
turning
round
one
of
those
stars,
the
Sun?
The
key
to
these
questions
is
“evidence”,
which
means
the
facts,
signs
or
objects
that
make
you
believe
something
is
true.
Sometimes
evidence
means
actually(实际上)
seeing
(or
hearing,
feeling,
smelling...)that
something
is
true.
Astronauts
have
travelled
far
enough
from
the
Earth
to
see
with
their
own
eyes
that
it
is
round.
Sometimes
our
eyes
need
help.
The
“evening
star”
looks
like
bright
twinkle
in
the
sky,
but
with
a
telescope(望远镜)
you
can
see
that
it
is
a
beautiful
ball.
Something
that
you
learn
by
direct
seeing
(or
hearing
or
feeling...)
is
called
an
observation.
Often
evidence
isn’t
just
observation
on
its
own,
but
observation
always
hides
at
the
back
of
it.
If
there’s
been
a
murder,
often
nobody
(except
the
murderer
and
the
dead
person!)
actually
observed
it.
But
detectives
can
gather
together
lots
of
other
observations
which
may
all
point
towards
the
suspect.
If
a
person’s
fingerprints
match
those
found
on
a
knife,
this
is
evidence
that
he
touched
it.
It
doesn’t
prove
that
he
did
the
murder,
but
it
can
help
when
it’s
joined
up
with
lots
of
other
evidence.
Prediction(预测)
helps
to
look
for
evidence.
Scientists
make
a
guess
about
what
might
be
true.
For
example,
if
the
world
is
really
round,
we
can
predict
that
any
of
us,
going
on
and
on
in
the
same
direction,
should
eventually
find
ourselves
back
where
we
started.
People
sometimes
say
that
you
must
believe
in
feelings
deep
inside,
but
not
all
the
inside
feelings
are
real
evidence.
What
can
we
do
about
all
this?
When
somebody
tells
you
something
that
sounds
possible,
think
to
yourself:
“Is
there
any
evidence
for
that?”
And,
next
time
somebody
tells
you
that
something
is
true,
why
not
say
to
them:
“What
kind
of
evidence
is
there
for
that?”
Remember,
always
think
carefully
before
you
believe
a
word.
26．Which
of
the
following
is
TRUE
according
to
the
passage?
A．What
you
see
directly
is
real
evidence.
B．Prediction
helps
to
prove
something
if
it
is
true
C．people
should
always
believe
their
inside
feelings.
D．Astronauts
find
the
Earth
is
round
with
a
telescope
27．Why
does
the
writer
use
the
example
of
a
detective
in
Paragraph
4?
A．To
explain
what
the
prediction
is.
B．To
tell
what
observation
is
called.
C．To
introduce
how
detectives
work.
D．To
prove
evidence
is
not
just
observation
28．The
underlined
word
“eventually”
in
Paragraph
5
means
________.
A．finally
B．probably
C．completely
D．luckily
29．What’s
the
best
title
of
the
passage?
A．Evidence
speaks
B．Scientists
make
predictions
C．Inside
feelings
help
get
ideas
D．Observation
offers
the
facts
四、短文选词填空

Look
up
at
the
sky
at
night.
What
can
you
see?
Before
electric
lights,
people
could
often
see
about
2,500
different
stars.
Now,
light
fills
the
skies
over
our
cities.
This
is
called
light
30．.
Because
of
it,
people
in
cities
can
often
only
see
about
ten
31．!
Most
of
the
time,
light
helps
us.
We
can
32．
because
of
it.
It
gives
plants
energy.
But
light
isn’t
always
33．.
We
need
times
of
dark
34．.
One
hundred
years
ago,
we
had
those
times
of
dark.
Now
the
night
is
like
day.
Some
scientists
are
worried
about
35．
this
light
effects（影响）our
health.
These
scientists
are
studying
the
effects
of
light
pollution.
Other
scientists
are
finding
ways
to
36．
light
pollution
and
make
our
lives
better.
For
example,
many
street
lights
now
have
covers.
The
covers
focus
the
light
37．
the
ground.
They
stop
the
light
from
going
38．
into
the
sky.
They
also
save
energy.
The
covers
are
a
39．change,
but
they
can
40．
have
a
positive（正面的）effect.

be
true.”可知，预测有助于寻找证据，由此用证据来证明你的预测是否正确。”故选B。
27．
推理判断题。根据“Often
evidence
isn't
just
observation
on
its
own,
but
observation
always
hides
at
the
back
of
it.”可知，通常证据不只是观察本身，而是观察隐藏在它背后的真相。再由句子“But
detectives(侦探)can
gather
together
lots
of
other
observations
which
may
all
point
towards
the
suspect(嫌疑犯).”可知，侦探们可以收集很多其他的观察结果，这些观察结果可能都指向嫌疑犯。可知，作者在第4段中使用侦探的例子就是为了证明证据不只是观察。但可以通过观察，寻找证据。故选D。
28．
词义猜测题。根据“For
example,
if
the
world
is
really
round,
we
can
predict
that
any
of
us,
going
on
and
on
in
the
same
direction,
should
eventually
find
ourselves
back
where
we
started”可知，如果世界真的是圆的，在在同一个方向上继续前进，最终应该回到起点。故选A。

Grade
9
in
Sunshine
Middle
School
held
a
hot
debate
in
the
class
meeting.
They
talked
about
whether
they
should
listen
to
music
or
not
while
studying.
Some
students
thought
it
was
good
for
study.
Listening

music
while
studying
can
help
relax
the
brain.
But
others
thought
it
was
bad
for
study.
They
thought
the
students
would
be
easily
distracted.
For
me,
I
would
like
to
join
the
negative
side.
I
think
we
should
pay
attention
to
what
we
are
studying.
If
we’re
tired,
we
can
listen
to
music
without
thinking
about
anything.
It’s
a
waste
of
time
listening
to
music
while
studying.
