三、关系副词why
1.why引导定语从句时,先行词往往是表示原因的词(如reason,explanation,excuse等),在从句中作原因状语。
Do you know the reason why she burst into tears?
你知道她突然大哭的原因吗?
This is the explanation why he changed the plan.
这是他改变计划的解释。

他这次考试成功的原因是他学习非常努力。
四、关系代词和关系副词的选择
当先行词是表示时间的time,day等或表示地点的place,house等时,一定要注意分析从句的结构。如果缺少主语或宾语,应用关系代词that或which,如果缺少时间状语或地点状语,应用关系副词when或where。
I'll never forget the days which/that we spent together.(which/that作spent的宾语)
我永远忘不了我们一起度过的日子。
His father works in a factory which/that makes radio parts.(which/that在从句中作主语)

The house where I lived ten years ago has been pulled down.(where在从句中作地点状语)
我十年前住的房子已经被推倒了。

(1)倍数+as+形容词/副词原级+as...
(2)倍数+形容词/副词比较级+than...
(3)倍数+the+性质名词+of...
(4)The+名词+be+倍数+what从句
(5)The+名词+be+倍数+that/those of...
