1)which 引導(dǎo)的定語(yǔ)從句結(jié)構(gòu)
• which是關(guān)系代詞,which后面應(yīng)該加缺主語(yǔ)或者賓語(yǔ)的句子,在這個(gè)句子中,which要作成分,作主語(yǔ)或者賓語(yǔ)
2)in which+完整的句子,which在定語(yǔ)從句中作in的賓語(yǔ),所以不能作后面句子的主語(yǔ)
3)名詞+of which+謂語(yǔ)動(dòng)詞,of which來(lái)修飾名詞,名詞在定語(yǔ)從句中作主語(yǔ),所以后面直接跟謂語(yǔ)動(dòng)詞
I have five books three of which are borrowed from Mary.
4)介詞+ which +to do 其功能相當(dāng)于定語(yǔ)從句。The key with which to open the door is lost.
5)定語(yǔ)從句的省略結(jié)構(gòu):
• 如果that / which在定從中作 賓語(yǔ),可以省略.
sub.+ vt.+ n.+ (which / that) + sub.+ vt.→s.+ vt.+ n.+ s.+ v.
• 當(dāng)做題時(shí),若發(fā)現(xiàn)兩個(gè)名詞在一起,但是似乎連不上,則一定省略that/which,則動(dòng)詞為vt,做謂語(yǔ)。
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。
