"I saw a woman running toward me in the dark．Before I could recognize who she was, she had run back in the direction ________ she had come．
A. of which
B. by which
C. in which
D. from which"

Answer 1

"答案D
思路解析：from which引导定语从句，which代替先行词direction，作介词from的宾语。from与定语从句中的come构成短语come from，意为“来自”。
绿色通道：关系代词whom, which在从句中作介词的宾语时，可以跟介词一起放在从句与主句之间(that, who不可以)，也可以把介词放在从句中有关动词的后面，使关系代词紧跟它所修饰的先行词。"
