Answer 3

第三题第三句不能用where于逗号去不去没有关系。因为这句话想表达的是：这间屋子的窗户朝东。屋子的窗户（the window of the room) ，用which 代替the room，得：the window of which ，所以句子可以写成：He still lives in the room, the window of which faces to the east. （第二句），再把介词加关系代词调到the room 后得：He still lives in the room, of which the window faces to the east.
第四句中in the middle of 是介词词组，等于一个介词的用法只能用关系代词which 。

Answer 4

英语定语从句相当于一个形容词，是用来形容一个名词的。是一个有引导词的完整的句子
