Question

She wrote a letter to her father ______ she made her secret known.

A. in which B. where C. A or B D. which
答案是A， 我比较偏向C，限制性定语从句中 in which= where的么？
不明白诶。。。。能不能详细的解释下呢

Answer 1

C
in
which
她给爸爸写了一封信，在这封信里面她讲了她的秘密。
写信的内容是in
the
letter
所以做定语从句来修饰这封信时，用in
which。
她给爸爸写了一封信，什么样的信呢？在里面透露了秘密的信。

Answer 2

C
首先这个定语从句是修饰letter的
还原从句，为了是从句有完整的意思，必须是she
made
her
secret
known
in
the
letter
所以用in
which
