从句用虚拟语气的情况。
当说话人认为句子所述的是不真实的或极少有可能发生或存在的情况时。从句虚拟语气动词时态的形式如下:
(1)如果从句表示与现在事实相反,谓语动词用一般过去时。如:
You
look
as
if
you
didn’
t
care.
你看上去好像并不在乎。
He
talks
as
if
he
knew
where
she
was.
他说话的样子,好像他知道她在哪里似的。
(2)从句表示与过去事实相反,谓语动词用“had+过去分词”。如:
He
talks
about
Rome
as
if
he
had
been
there
before.
他说起罗马来好像他以前去过罗马似的。
The
girl
listened
as
if
she
had
been
turned
to
stone.
那女孩倾听着,一动也不动,像已经变成了石头似的。
(3)从句表示与将来事实相反,谓语动词用“would/could/might+动词原形”。如:
He
opened
his
mouth
as
if
he
would
say
something.
他张开嘴好像要说什么。
It
looks
as
if
it
might
snow.
看来好像要下雪了。
