状语从句
状语从句在复合句中修饰主句中的谓语动词、形容词或副词。状语从句一般由从属连词引导。从句位于句首或句中时通常用逗号与主句隔开
,
位于句尾时可以不用逗号隔开。状语从句分类如下
:
本单元着重介绍了以下三种状语从句。
1.unless
引导的条件状语从句。
unless
意为
“
如果不
;
除非

if...not
。例如
:
We
’
ll go to the town unless it rains tomorrow.=We
’
ll go to the town if it doesn
’
t rain tomorrow.
假如明天不下雨
,
我们就去城里。
注意
:unless
和
if
引导条件状语从句时
,
从句用一般现在时表示将来
