定语从句：介词+关系代词
1. 用法 关系代词在定语从句中作介词宾语时, 从句常常由 “介词+关系代词”引导2. 结构 先行词是人用 “介词+whm” 先行词是物用 “介词+which”e.g. The schl in which he nce studied is very famus.
The girl abut whm we are talking is a dctr.
我们正在谈论的那个女孩是个医生。
他曾经上学的学校非常著名。

1.有些含有介词的动词短语一般不拆开, 介词仍放在后面,如: lk fr, lk after, lk frward t, take care f等e.g. The baby whm the nurse is lking after is very healthy.
The winter hliday that we have lked frward t fr a lng time is cming.

The reasn ________________ he was late isn’t clear.
I remember the day ________________ I g abrad.
in which = (where)
n which = (when)
