1)which 引導的定語從句結構
• which是關系代詞,which后面應該加缺主語或者賓語的句子,在這個句子中,which要作成分,作主語或者賓語
2)in which+完整的句子,which在定語從句中作in的賓語,所以不能作后面句子的主語
3)名詞+of which+謂語動詞,of which來修飾名詞,名詞在定語從句中作主語,所以后面直接跟謂語動詞
I have five books three of which are borrowed from Mary.
4)介詞+ which +to do 其功能相當于定語從句。The key with which to open the door is lost.
5)定語從句的省略結構:
• 如果that / which在定從中作 賓語,可以省略.
sub.+ vt.+ n.+ (which / that) + sub.+ vt.→s.+ vt.+ n.+ s.+ v.
• 當做題時,若發(fā)現兩個名詞在一起,但是似乎連不上,則一定省略that/which,則動詞為vt,做謂語。
6)定從的特殊省略
• the way (in which) + 句子
• the reason (why that)+句子
• the time (that / when)+句子
• By the time省that+句子,句子。
