条件与让步状语从句

外研版选择性必修第二册 Unit 6 重点语法。


一、条件状语从句

  • 引导词:if, unless (= if not), as long as, provided that, on condition that
  • 时态规则:主将从现(主句为将来时,从句用一般现在时表示将来)。

二、让步状语从句:-ever 与 no matter

引导词引导状语从句引导名词性从句示例
no matter + wh-×No matter where you go, keep in touch.
wh-everWhoever arrives first will get the prize. (主从)

三、although / though 与 as 的倒装让步

as 引导让步状语从句时,必须采用倒装结构(将表语、状语或动词原形提前):

  • Rich as he is, he lives a simple life.(虽然他富有)
  • Hard as they tried, they couldn't solve the problem.(尽管他们很努力)
