Question

It was not untill 。。。。did he ...,词句要倒装吗？

Answer 1

not
until
引起的时间状语置于句首时，句子的主谓应部分倒装。由
not
until
引导的时间状语从句位于句首时，主句应部分倒装，从句语序不变。如：
Not
until
1998
did
he
return
to
his
hometown.
直到
1998
年他才回到家乡。
Not
until
Father
came
back
did
we
begin
to
have
supper
last
night.
昨晚直到父亲回来，我们才开始吃晚饭。
注意：当
not
until
引导的状语或状语从句用于强调句型时，句子的主语不倒装。如将上两句改为强调句应为：
It
was
not
until
1998
that
he
returned
to
his
hometown.
It
was
not
until
Father
came
back
that
we
began
to
have
supper
last
night.
