三、
虚拟语气注意点：
1.假设条件从句谓语动词发生的时间与主句所假设的谓语动词不一致，叫做错综条件虚拟语气。主句和从句的谓语动词要依照假设的时间而定。

the
weather
had
been
finer,
the
crops
would
be
growing
still
better.
If
you
had
followed
the
teacher’s
advice,
you
wouldn’t
be
in
the
hospital.
三、
虚拟语气注意点：
2.当insist表示“坚持认为”，suggest表示“表明、暗示”时，后面的宾语从句不用虚拟语气。
He
insisted
that
he
had
not
entered
the
house,
and
(he
insisted)
that
he
should
be
set
free.
His
pale
face
suggested
that
he
was
weak.
