Scientists
without
Laboratories
When
you
hear
the
word“scientist”,
what
do
you
think
of?
Many
people
think
scientists
are
people
in
clean
white
coats
who
work
in
labs.
And
some
scientists
do
work
in
labs.
But
there
are
__1__
scientists
who
work
in
woods
and
jungles.
These
scientists
are
called“animal
behavior(行为)scientists”,
and
they
study
animals
as
they
live
in
nature.
Why
don't
these
scientists
catch
animals
and
study
them
in
zoos？The
__2__
is
in
the
word“behavior”.
Animal
behavior
scientists
want
to
learn
__3__
animals
behave
in
their
wild
homes.
When
animals
live
in
cages(笼子)or
in
zoos,
they
do
not
act
the
same
as
they
do
when
they
are
__4__.
They
may
fight
__5__
each
other,
or
they
may
not
eat,
or
they
may
not
raise(抚养)their
babies
as
they
usually
would.
To
see
real
animal
behavior,
scientists
must
go
where
the
animals
__6__.
So
animal
behavior
scientists
go
into
the
jungles,
the
woods
or
the
desert.
There,
their
most
important
__7__
are
their
eyes
and
ears.
They
watch
and
listen
to
the
animals
very
__8__.
They
write
down
everything
that
happened
in
notebooks.
__9__
they
live
near
the
animals,
the
scientists
are
careful
not
to
frighten
them.
If
the
scientists
are
lucky,
the
animals
will
__10__
no
attention
to
them.
Then
the
scientists
can
see
how
the
animals
really
live.
The
animal
behavior
scientists
hope
what
they've
learned
about
animal
behavior
can
provide
clues(提供线索)to
help
people
learn
to
live
together
more
happily.

Round
watermelons
do
not
sit
nicely
on
shelves.
So
some
clever
farmers
have
solved
the
watermelon
problem.
They
make
their
watermelons
grow
in
square
glass
boxes
so
the
watermelons
become
square.
The
only
problem
now
is
the
price.
The
square
watermelons
cost
about
80
dollars
each.
Many
people
know
the
saying,
“Roses
are
red,
violets
are
blue,
sugar
is
sweet
and
so
are
you.
”
Well,
today
the
poem
needs
to
change
to
“Roses
are
red,
and
roses
are
blue.
”Recently,
Australian
scientists
have
just
discovered
that
when
they
put
a
chemical
from
a
blue
flower
into
a
rose,
they
can
create
a
nearly
100%
blue
rose.
Some
scientific
inventions
are
beautiful,
not
just
useful！
For
many
years
Chinese
scientists
have
been
working
on
developing
new
kinds
of
stronger
rice
and
now
they
have
produced
a
new
kind,
called
super
rice.
Super
rice
not
only
can
protect
itself
against
insects(昆虫)and
diseases,
but
also
can
produce
more
than
any
other
kind
of
rice.
Today
farmers
can
grow
almost
one
and
a
half
times
more
rice
than
they
could
grow
in
the
past.
Doctors
might
be
able
to
use
vegetables
to
fight
cancer
now.
US
scientists
have
discovered
a
way
to
put
a
chemical
into
tomato
plants
while
they
are
growing.
When
cancer
patients
eat
the
tomatoes,
the
tomatoes
will
fight
the
cancer
in
their
bodies.
These
cancer?fighting
vegetables
are
not
yet
for
sale(出售),
because
scientists
have
not
finished
testing
them.

B（荣德原创）
On
June
21,
2020,
the
“summer
solstice(夏至)”
day,
there
was
an
astronomical
scene
“annular
eclipse”
in
China.
Su
Yi,
an
astronomer
and
professor
of
Nankai
University,
said
that
the
“annular
eclipse”
was
the
most
surprising
is
astronomical
phenomenon(现象)
in
2020.
The
“annular
eclipse”
will
come
to
China
again
about
ten
years
later.
As
a
satellite
of
the
earth,
the
moon
moves
around
the
earth.
As
a
planet
in
the
solar
system,
the
earth
moves
around
the
sun
with
the
moon.
Solar
eclipses
and
lunar
eclipses
are
the
result
of
these
two
movements.
When
the
sun,
the
moon
and
the
earth
are
in
a
straight
line,
and
the
moon
is
between
them,
a
solar
eclipse
will
happen.
A
solar
eclipse
includes
total
eclipse,
the
partial
eclipse
and
the
annular
eclipse.
If
the
moon
is
far
away
from
the
earth
on
that
day,
and
the
sun
is
relatively
close
to
the
earth,
because
the
apparent
circular
surface
of
the
moon
is
small
and
cannot
completely
cover
the
sun,
an
“annular
eclipse”
will
happen.
Su
Yi
said
that
when
the
“annular
eclipse”
took
place,
the
moon
only
covered
most
of
the
sun's
center,
revealing
(露出)a
circle
of
the
sun's
edge,
like
a
“gold
ring”.

The
“annular
eclipse”
will
nearly
come
to
China
again
____.
A.
in
2025
B.
in
2030
C.
in
2040
D.
in

There
are
____
kinds
of
eclipse
in
the
solar
eclipses.
A.
three
B.
four
C.
five
D.

What
does
the
“annular
eclipse”
mean?

Have
you
ever
rubbed
your
hands
together
when
they
get
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
discover
friction!
WHAT
YOU'LL
NEED：
?A
piece
of
soap　?Water　?Your
hands
WHAT
TO
DO：
1.
Make
sure
your
hands
are
dry.
2.
Rub
your
hands
together
until
you
feel
the
heat
of
your
hands.
3.
Now,
use
a
piece
of
soap
and
water
to
get
your
hands
very
slippery
(滑的).
4.
Try
to
make
friction
happen
while
your
hands
are
slippery.
5.
Please
write
down
what
has
happened.
LET'S
TALK!
Friction
is
a
kind
of
energy
that
happens
when
two
things
rub
together.
When
friction
happens,
it
makes
heat!
When
your
hands
are
slippery,
they
won't
make
much
friction
and
your
hands
won't
get
so
hot.
DID
YOU
KNOW?
1.
Friction
happens
when
you
stop
your
fast
running
bike.
2.
Ancient
people
made
fires
by
rubbing
two
pieces
of
wood
together.
Friction
happened
though
they
didn't
know
it.
EVERYDAY
ACTION：
Friction
is
everywhere.
Have
you
ever
noticed
situations
where
friction
is
happening?
If
not,
ask
your
parents
to
take
you
out
in
a
car.
If
they
are
not
too
hot,
touch
the
tires
(轮胎)
of
the
car
before
and
after
a
short
drive
to
see
how
much
heat
they
get
from
friction.

better
make
your
hands
____
to
get
heat
when
you
rub
them.
A.
slippery
B.
dry
C.

am,
on
Tuesday,
June
23rd,
2020,
at
the
Xichang
Satellite
Launch
Center(卫星发射中心)
in
Sichuan
Province,
the
last
satellite
of
the
third?generation
network
(第三代导航系统)was
sent
into
space.
It
is
the
55th
member
in
the
family
of
BeiDou.
It
belongs
to
China's
BeiDou
Navigation
Satellite
System
(BDS北斗卫星导航系统).
So
far,
59
satellites,
including
the
first
four
test
ones,
have
been
launched
from
Xichang.
With
the
development
of
China,
we

12
years.
So
far,
China
has
completed
the
third?generation
network
of
China's
BDS.
It
was
a
new
milestone
in
the
nation's
space
research
work.
The
launch
showed
our
country

任务型阅读
It
is
interesting
how
NASA(美国航空航天局)chose
their
astronauts
for
landing
them
on
the
moon.
They
chose
men
between
the
age
of
twenty
and
thirty?five.
There
were
about
fifty
of
them.
Many
were
air
pilots.
Others
were
scientists
with
two
or
three
degrees.
NASA
telephoned
each
man
they
were
going
to
choose
and
told
him
the
plans
and
the
danger
they
might
get
into.
They
then
asked
him
if
he
was
willing
to
be
trained
as
an
astronaut.
The
health
and
physical
condition
of
an
astronaut
was,
of
course,
very
necessary.
Only
those
in
very
good
health
and
physical
condition
were
chosen.
While
being
trained
to
be
astronauts,
they
went
through
many
courses.
They
studied
the
star
and
the
moon,
and
they
also
studied
geology
and
the
science
of
rocks.
This
was
necessary
because
astronauts
would
have
to
look
for
rocks
on
the
moon.
They
would
try
to
find
rocks
which
might
help
to
tell
the
age
of
the
moon.
They
were
all
trained
to
fly
in
helicopters.
They
were
also
taught
the
unknown
facts
about
the
conditions
in
space.
They
learned
all
the
technical
details
of
the
spaceships
and
rockets.
They
visited
the
scientists
and
engineers.
They
visited
the
factories
where
the
spaceships
and
rockets
were
built.
They
learned
how
every
part
of
a
spaceship
and
its
instruments
work.
They
also
learned
every
detail
of
the
ground?control
system.
In
a
word,
to
be
chosen
as
an
astronaut,
one
must
be
in
good
health,
well?
informed
in
science
and
good
at
piloting.

范文：
Dear
Lily,
Thanks
for
sending
the
letter
to
me.
Your
experiment
sounds
interesting.
I
am
interested
in
science，too.
I
think
science
is
very
interesting.
And
it
has
great
effects
on
our
everyday
lives.
Our
lives
would
surely
be
very
different
without
the
development
of
science.
I
always
wonder
what
life
would
be
like
without
computers
or
mobile
phones.
Scientific
discoveries
are
making
our
lives
better
and
better.
This
week
we
had
some
science
lessons，too.
I
enjoyed
learning
about
DNA.
It
is
really
one
of
the
most
amazing
things
on
the
earth！Scientists
are
doing
so
many
new
things
with
DNA.
I
think
it
will
change
the
world.
It
will
be
interesting
to
see
what
happens.
Yours,
Yang
