随着科技的发展,人类总有一天可以到太空旅游,对此人们有不同的看法,请谈谈太空旅游的利弊,表达自己态度.
随着科技的发展,毫无疑问人类总有一天会到太空旅行.(in
time)
With
the
development
of
technology,
there
is
no
doubt
that
people
can
travel
to
space
in
time.
因此展开了关于它利弊的激烈讨论(thus).
Thus
there
is
a
heated
discussion
about
its
advantages
and
disadvantages.
太空旅行有几个好处.第一,既然地球上居住了太多的人,我们可以旅行到太空去,或许这会让发现其他适合我们居住的星球成为可能(it
作形式宾语).
There
are
several
advantages.
First
of
all,
now
that
there
are
too
many
people
living
on
the
earth,
we
can
travel
to
space,
which
may
make
it
possible
to
find
new
places
to
live
in.
另外,太空旅行对其他领域的研究也有好处.(do
good
to…)
In
addition,
space
travel
does
good
to
other
research
fields.
相反的,它也有很多不好的地方.
On
the
contrary,
there
are
some
disadvantages.
首先,人类到其他星球生活的想法是不切实际的(~realistic)
Firstly,
the
idea
of
man
living
on
other
planets
is
unrealistic.
另外,价格是其他旅游的很多倍.
What’s
more,
the
price
is
many
times
as
expensive
as
other
trips.
总之,我们应该权衡利弊(balance).
In
a
word,
we
should
weigh
the
advantages
and
disadvantages.
我认为,对于人类来说,不管怎样,探索宇宙是很重要的.
Anyhow,
in
my
opinion,
it
is
of
great
importance
for
man
to
explore
the
universe.
