if引导的条件状语从句的同义句替换的例句

Answer 1

引导条件状语从句最常用的连词是if,由if引导的条件状语从句表示在某种条件下某事很可能发生。如:
if
you
ask
him,
he
will
help
you.如果你请他帮忙,他会帮你的。
if
you
fail
in
the
exam,
you
will
let
him
down.如果你考试不及格,你会让他失望的。
另外,if从句还表示不可实现的条件或根本不可能存在的条件,也就是一种虚拟的条件或假设,从句多用一般过去时或过去完成时。如:
if
i
were
you,
i
would
invite
him
to
the
party.如果我是你,我会邀请他参加聚会。
i
would
have
arrived
much
earlier
if
i
had
not
been
caught
in
the
traffic.如果没有堵车,我会到的早一点儿。
