Question

why和when之间为什么用to

Answer 1

I'm
sure
I
can
clearly
select
aspects
in
their
friendship,from
possiple
reason
why
to
when
it
all
started.
翻译：我确信我能明确地选出他们友谊的几个方面，从他们结下友谊的可能的原因，到这份友情开始于何时。
原句可以这样断句：I'm
sure
I
can
clearly
select
aspects
in
their
friendship,from
（possiple
reason
why
）to（
when
it
all
started）.
括起来结构就清楚了，找到from
to
词组
从·····到······
reason
可以和that
，which还有why
连用
reason在定语从句中
The
reason
why...is
that...
这是特定句型,
why引导定语从句,is后的用词为that。
如:The
reason
why
(we
failed)
is
that
(the
costs
were
too
high).我们失败的原因是成本太高。
在这里,we
failed是一个需要解释的情况,所以用
the
reason
why
。
The
reason
why
(some
people
ask)
is
that(
they
have
questions).
人们问的理由是他们有疑惑。
