he had shown himself careless of personal safety where the life of his colleagues might be at risk

Question

为什么要用WHERE而不用其他的呢 ?介词形式是什么 ON WHICH吗?请说的详细一点 谢谢

Answer 1

首先，这不是一个很好的例句。这句话是一个翻译公司先搞出来的，然后被好多中国教材抄了过去。这不是实际生活中用的话。虽然它的语法是对的(除了life要用复数)，但是语义不很通。where在这句话里的意思是"在那种情况下"，相当于in
which
(不是on
which)。
He
had
shown
himself
careless
of
personal
safety
in
which
the
lives
of
his
colleagues
might
be
at
risk.
他从来不把自己的安全当回事，这一点会危及同事们的生命。
我翻译的中文比原文要通顺。实在不知道如何把原文不通顺之处翻译出来。
:-(
如果用其它连词如when:
He
is
first
of
all
a
sportsman,
tireless,
and
careless
of
personal
safety
when
riding
and
big
game
hunting,
essentially
a
man
of
action.
那么就没有暗含的因果关系，而仅是简单的时间状语了。
