heard
of
the
satellite(卫星)
called
the
Early
Bird,
which
was
built
by
a
group
of
scientists
from
14
countries
Up
till
now
dozens
of
satellites
have
been
put
into
11

and
they
help
people
in
many
ways.
You

on

of

with

of

They

Satellite

are
quite
useful
in

For

satellites
for

are
used
to
send
radio

to
another.

三、阅读理解
A
What
shoul
( http: / / www.21cnjy.com )d
you
take
in
with
you
when
you
take
an
exam
Pen,
pencil,
eraser,
ruler…,
and
don't
forget
a
bottle
of
water!【来源：21·世纪·教育·网】
According
t
( http: / / www.21cnjy.com )o
a
study
at
the
British
Psychological(
心理学的)
Society
Annual
Conference
held
in
London,
students
who
bring
water
into
exams
may
improve
their
grades
by
up
to
10
percent.
Scienti
( http: / / www.21cnjy.com )sts
at
the
University
of
East
London
and
the
University
of
Westminster,
UK,
did
a
study
on
447
students.
The
students
were
studying
for
different
degrees(学历)
at
the
University
of
East
London.
Only
25
percent
of
them
entered
the
exam
hall
with
something
to
drink.
Scientists
( http: / / www.21cnjy.com )then
compared
their
exam
results
with
their
normal
schoolwork
grades.
They
found
that
all
those
who
had
brought
drinks
with
them
got
better
grades
by
between
2
and
10
percent.
It
is
unclear
( http: / / www.21cnjy.com )
why
drinking
water
improves
exam
results.
But
scientists
say
having
enough
water
in
our
bodies
and
not
feeling
thirsty
could
have
a
helpful
effect
on
our
brains.
Drinking
water
may
also
cut
down
on
anxiety(焦虑),
which
has
a
bad
effect
on
exam
performances,
according
to
Chris
Pawson,
PhD,
of
the
University
of
East
London.
"Whate
( http: / / www.21cnjy.com )ver
the
explanation,
it
is
clear
that
students
should
try
hard
to
stay
hydrated(含水的)
with
water
during
exams,"
he
said.
So
next
tim
( http: / / www.21cnjy.com )e,
when
you
are
going
to
have
a
big
exam,
try
bringing
a
bottle
of
water
with
you.
Who
knows—it
may
help
you
pass
the
exam!
21.
How
much
may
th
( http: / / www.21cnjy.com )e
students
improve
their
grades
most
if
they
bring
water
into
exams
A.
By
2%.
B.
By
8%.
C.
By
10%.
D.
By
25%.
22.
How
many
students
in
the
study
got
better
grades
A.
About
112
students
who
brought
drinks
or
water
into
their
exams.
B.
All
the
447
students
who
come
from
the
University
of
East
London.
C.
About
300
students
who
took
part
in
the
study.
D.
About
10
percent
of
the
students
who
studied
different
subjects.

Have

your

together
when
they

cold
Why
do
we
do
that
We
do
that
for
friction.
Friction
happens
when
two
things
that
aren't
very
smooth
rub
together
to
make
heat
energy.
The
faster
you
rub
two
things
together,
the
more
friction
(and
heat)
you
can
make.
Let's

Friction
is
( http: / / www.21cnjy.com )
an
energy
that
happens
when
two
things
tub
together.
When
friction
happens,
it
makes
heat!
When
your
hands
are
slippery,
they
won't
make
very
much
friction
and
your
hands
won't
get
so
hot.

We
often
praise
the
world
of
science.
It
explains
( http: / / www.21cnjy.com )
the
world
and
makes
our
lives
easier
with
technology.
One
of
the
most
exciting
fields
in
science
is
artificial
intelligence
(人工智能,AI).
This
is
an
area
where
scientists
are
working
on
creating
machines
that
think
like
humans.21
cnjy
com
Howeve
( http: / / www.21cnjy.com )r,
one
of
the
most
famous
scientists
has
a
very
dark
warning
for
us
about
this
type
of
technology.
"The
( http: / / www.21cnjy.com )development
of
full
artificial
intelligence
could
spell
the
end
of
the
human
race,"
said
Professor
Stephen
Hawking
to
the
BBC.
Hawking
is
a
( http: / / www.21cnjy.com )well-known
British
physicist
and
author
of
bestselling
science
book
A
Brief
History
of
Time.
This
warning
came
after
commenting(评论)
the
technology
he
uses
to
speak
with.
As
Hawking
has
got
a
serious
disease
called
ALS,
he
needs
an
AI
computer
to
communicate.
The
computer
learns
how
Hawking
thinks
and
suggests
the
words
he
may
want
to
use
next.
This
is
a
basi
( http: / / www.21cnjy.com )c
type
of
AI,
which
is
very
useful,
yet
Hawking
fears
the
possibility
of
creating
technology
that
can
match
or
surpass
human
intelligence.
And
it's
easy
to
imagine
how
terrible
things
may
be.
Many
TV
shows
and
films
show
big,
killer
machines
that
are
far
cleverer
than
us.
"Humans,
who
are
limited(限制)
by
slow
biological
evolution(进化),
couldn't
compete,"
said
Hawking.
But
not
every
( http: / / www.21cnjy.com )scientist
is
pessimistic(悲观的)
about
AI
technology.
"I
believe
we
will
be
in
control
of
the
technology
for
a
long
time,"
said
Rollo
Carpenter,
creator
of
Cleverbot
in
the
UK,
which
is
a
software
program
that
remembers
past
conversations,
"The
advantages
of
it
to
solve
many
of
the
world
problems
will
be
realized."
In
wha
( http: / / www.21cnjy.com )t
direction
do
you
think
AI
is
heading
Should
we
be
hopeful
or
fearful
31.
Which
of
the

is
TRUE
about
AI
A.
It
makes
our
lives
easier.
B.
The
technology
is
not
very
popular
now.
C.

haven't
controlled
the
technology.

八、阅读与表达(问答式)
There
have
( http: / / www.21cnjy.com )
been
many
great
inventions,
things
that
changed
the
way
we
live.The
first
great
inventions
was
one
that
is
still
very
important
today—the
wheel(车轮).
This
made
it
easier
to
carry
heavy
things
and
to
travel
long
distances.
For
( http: / / www.21cnjy.com )hundreds
of
years
after
that
there
were
few
inventions
that
had
as
much
effect
as
the
wheel.Then
in
the
early
1800's
the
world
started
to
change.
There
was
little
unknown
land
left
in
the
world.
People
didn't
have
to
explore
much
any
more.
They
began
to
work
instead
to
make
life
better.
In
t
( http: / / www.21cnjy.com )he
second
half
of
the
19th
century
many
great
inventions
were
made.
Among
them
were
the
camera,
the
light
and
the
radio.
These
all
became
a
big
part
of
our
life
today.
The
first
( http: / / www.21cnjy.com )part
of
the
20th
century

century
brought
new
ways
to
help
people
get
over
diseases.
They
made

new

continued
to
be
made.
Man

looking
for
ways
to
go
into

a
step.
Since
then
other
countries,

Japan,
have
made
their
steps
