Question

This is the place ____I have ever visited.

Answer 1

D，陈述句应该是I
HAVE
EVER
VISITED
THIS
PLACE,
作者为强调THE
PLACE这个地方，选择使用定语从句I
HAVE
EVER
VISITED来修饰THE
PLACE.
然而VISIT是及物动词，后边一定要加名词做宾语的，选择答案中只有WHICH能代替名词做宾语，这裏特指THE
PLACE，
只能选D
A是副词，且不能单独引导从句
B表示时间，是连词，能引导从句，可是不能做VISIT的宾语
C看似可以，可是WHERE也是副词，能引导从句，可是不能做宾语。

Answer 2

因为the
place是宾语，得用which来表示。上述句子应该这么表达：
this
is
the
place
which(或者用that）i
have
erver
visited或者
this
is
where
i
have
ever
visited
