  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。

  (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
