Question

She'll never forget her stay there______ she found her son who had gone missing two

Answer 1

翻译：她将永难忘记她在那儿的停留，（因为）在那次停留期间她找到了两年前失踪的儿子。
解释：此题考查定语从句的关系词的选择。
1.
先行词是her
stay，而不是there，因为定语从句所修饰的先行词只能是代词/名词（短语），而不能是副词。
此题中的stay是一个名词，意思也是“停留/逗留”。
2.
将先行词her
stay放入定语从句中，连接为：
(when)
she
found
her
son
who
had
gone
missing
two
years
before
=
(in/during
which)
she
found
her
son
who
had
gone
missing
two
years
before
=
(in/during
her
stay)
she
found
her
son
who
had
gone
missing
two
years
before
在她（在那儿的）逗留期间，她找到了两年前失踪的儿子。
很明显，该定语从句缺少时间状语。
即所谓的关系副词when
=
介词(in/during)
+
关系代词which
=
介词(in/during)
+
先行词(her
stay)。
3.
而关系代词that/which只能等于先行词her
stay，无法直接放入定语从句中做成分；
where在定语从句中充当地点状语，而不是时间状语。

Answer 2

选d。根据her
stay可知，表示的是“她呆在那儿的时候”，指的是时间，而不是地点。there不能做定语从句的先行词，因此不能先where。
