Answer 1

火星上的生活
1.我们的行星地球正变得越来越拥挤，越来越受污染；我们可望重新开始，在火星上建立一个更好的家园；
2.首先，交通应当好得多；很快，航天飞机的速度将达到光速的一半；
3.人类要生存，就需要食物.水和空气；科学家希望使植物发展，能在火星上种植，以产生我们需要的食物和氧气；但是，还不能确定它们是否能产生水；
4。火星上的重力只相当于地球上的3/8，人们在火星上得穿上特制的靴子，以增加重量。
Our
own
planet,Earth,is
becoming
more
and
more
crowded
and
polluted.Hopefully,we
can
start
again
and
build
a
better
world
on
Mars.First
of
all,transport
should
be
much
better.In
a
very
short
time,space
shuttles
will
travel
at
half
speed
of
light.Humans
meed
food,water
and
air
to
survive.Scientists
hope
to
plants
that
can
grow
on
Mars.These
plants
will
produce
the
food
and
oxygen
that
we
need.However,it
is
not
certain
if
these
plants
will
be
able
to
produce
water
.The
gravity
on
Mars
is
only
about
three-eights
of
the
gravity
on
Earth.Humans
on
Mars
would
have
to
wear
special
boots
to
make
themselves
heavir.
