Humans

a
second
home,
humans
have
conducted
experiments

Inference
&
Evidence
A.
?One
option
is
to
explore
other
planets
to
see
if
we
could
live
on
them.
D.?
In
the
1960s
and
1970s,
the
greatest
fear
was
the
human
race,
and
possibly
all
advanced
life
forms
on
the
planet,
could
be
wiped
out
by
nuclear
missiles.
E.?
There
is
no
doubt
that
humankind
is
drawn
towards
Mars,
with
dreams
of
making
it
our
second
home.
For
now,
human
settlement
of
Mars
is
still
away.
G.
?
The
two-year
experiment
was
not
a
success,
it
did
provide
us
with
a
better
understanding
of
how
humans
be
able
to
live
on
another
planet.

Would
you
like
to
be
one
of
the
first
people
to
live
on
Mars?
Why
or
why
not?
2.
Which
is
better,
to
live
on
Mars
or
to
solve
Earth's
problems?
Why?
No.
It
is
hard
to
say
if
the
conditions
on
Mars
are
safe
and
proper
for
human
beings
to
live
on
it.
I
think
that
it
is
better
to
try
to
solve
Earth's
prblems.
On
the
one
hand,
Earth
is
the
place
where
life
began,
where
life
has
lived
for
billions
of
years.
On
the
other
hand,
it
is
easier
and
safer
for
us
to
protect
and
save
our
planet
than
to
move
to
another
distant
planet.

Can
you
think
of
a
“Plan
C”
to
save
people
from
the
problems
on
Earth?
All
countries
get
together
to
create
the
Community
of
Shared
Future
for
Mankind.
In
pursuing
its
own
development,
any
country
promotes
the
common
development
of
all
countries.
All
should
be
aware
that
there
is
only
one
earth
for
mankind
and
all
countries
live
in
one
world.
Countries
should
respect
each
other
and
treat
each
other
as
equals,
pursue
win-win
cooperation
for
common
development,
ensure
the
security
of
common
comprehensive
cooperation
and
sustainable
development,
and
promote
inclusive
exchanges
and
mutual
learning
among
different
civilizations

Share
your
survival
story
with
the
class
For
me.
it
is
not
a
dream
but
a
lonely
island
I
am
living
on.
Faced
with
a
tropical
heat,
I
must
find
drinking
water
within
hours,
or
he
will
become
a
piece
of
fry
wood
before
leaving
here
safely.
Without
water,
anyone
may
survive
for
only
three
days.
Without
food,
he
or
she
can
only
survive
for
three
weeks.
Surrounded
by
beautiful
coral
reefs,
I
have
to
make
nets
or
fishhooks
to
catch
fish,
but
I
also
has
to
avoid
the
deadly
sharks
that
inhabit
the
island.
In
addition,
I
has
to
make
a
fire
to
build
proper
shelters
to
hide
from
dangers
like
poisonous
snakes.
I
can't
only
wait
to
be
saved
It
is
crucial
for
me
to
learn
how
to
make
fire
and
get
something
to
drink
and
eat
as
soon
as
possible.
Luckily,
I
manage
to
have
the
first
tasty
meal
on
the
island.
Looking
at
the
shining
stars,
I
am
confident
that
tomorrow
is
a
struggling
but
meaningful
day.
