条件状语从句条件状语从句主要由if或unless引导：

if条件句

1)if条件句：条件句用于陈述语气，表示假设的情况可能发生，其中

if

是“如果”的意思。e.g.Ifitrains,wewillstayathome.如果下雨我们就待在家里。Grammar2)

用法：

(1)条件状语从句通常由连词if引导，意为“如果、假如”，主句不能用be

going

to表示将来，而应该用shall,will。e.g.If

you

leave

now,

you

will

never

regret

it.

如果你现在离开，你永远都不会后悔。(2)if

“如果”，引导条件状语从句，主句用一般将来时，从句则用一般现在时。e.g.If

it

rains

tomorrow,

I

shan’t

climb

the

hills.如果明天下雨，我就不爬山了。(3)主句是祈使句或含有情态动词，从句也用一

般现在时。e.g.Please

call

me

if

he

comes

next

Sunday.如果他下周日过来请打电话给我。注意:

宾语从句中的if与条件状语从句if的区

别。宾语从句中的if

“是否”相当于

whether,引导宾语从句,时态需根据语境确定。如果主句用一般现在时,从句可以根据具体情况选用时态,如果主句用一般过去时,从句必须用过去时的某种形式。unless条件句unless引导的条件句，表示强烈的否定。翻译为“除非……”“非……不可”。e.g.You

will

fail

unless

you

work

harder.

你不努力就会失败的。=Youwillfailifyoudonotworkharder.注意:unless

从句里的谓语只能是肯定式,因为本身unless表示否定。单项选择。1.If
