总的来说,if
引导的从句有三种用法
1。
用于真实条件句
例如:
If
you
are
at
home,I
will
go
to
see
you.
If
you
work
hard
at
it,
you
can
get
success.
表示,只要按这样得条件去做,结果是肯定的。
2。
用于虚拟条件句
例如:
If
I
were
you,
I
wouldn't
go
there.
If
the
sun
rose
from
the
west,
I
would
call
you
Dad.
表示,条件是假设的,不真实的,因此,其结果也是不可能实现的。
注意句中谓语有所变化
3。
用于名词性从句,意思等于whether
or
not
表是否之意。
例如:
It
doesn't
matter
if
you
go
to
attend
the
meeting.
你是否参加会议没关系。
