　　定語從句:

　　which 引導(dǎo)的定語從句結(jié)構(gòu)

　　1)which是關(guān)系代詞，which后面應(yīng)該加缺主語或者賓語的句子，

　　在這個(gè)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(dòng)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(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)于定語從句。

　　The key with which to open the door is lost.

　　5)定語從句的省略結(jié)構(gòu)：

　　1. 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

　　s+vt+n1+n2+vt

　　*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。

　　6)定從的特殊省略

　　the way (in which) + 句子

　　the reason (why that)+句子　均為完整句

　　the time (that / when)+句子
