Question

it is not yet eight o'clock when he arrived home.什么从句?

Answer 1

it
is
not
yet
eight
o'clock
when
he
arrived
home.是状语从句，不过不是it
is
而应该是It
was...
it
is
1999
when
i
met
him是状语从句，同样is
应该改为was。再如：It
was
nine
o'clock
when
I
got
there.我到那里时时间是9点。
it
is
in
1999
that
i
met
him是强调句型。
同样is应改为was。
那it
is
in
1999
when
i
met
him
就不可以吗,不能理解为时间状语从句吗?when
i
met
him,
it
is
in
1999.
不可以。因为你如果想用状语从句，那就应该是It
was
1999
when
I
met
him.
而in
1999则是在强调这个介词短语所充当的时间状语。
强调句句式是固定的：It
is/was＋被强调部分＋that（人/物）/who/whom(人）+非被强调部分
如：I
met
them
in
the
street
yesterday.
It
was
I
that/who
met
them
in
the
street
yesterday.强调主语
It
was
them
that/whom
I
met
in
the
street
yesterday.强调宾语
It
was
in
the
street
that
I
met
them
yesterday.强调地点状语
It
was
yesterday
that
I
met
them
in
the
street.强调时间状语
