Is this just the place of interest ______ the foreign

1
这种句子你可以变换为陈述句来做。
即:
This is just the place of interest ______ the foreign visitors hope to pay a visit ____________.
the place of interest 名胜，这里就当是the place.
有个短语pay a visit to some place,注意有介词to,所以不能用that替代the place(that 不担任成分的)，而可以用which来替代the place。所以是 to which.
如果用where,那么就不用介词to,这里where相当于to which.

选2

这是考的关系代词和关系副词的选择问题。选哪一个要看从句的谓语动词，如果是及物动词，就选关系代词，如果是不及物动词，就选关系副词。
例：This is the mountain village which I visited last year. visit the mountain village ，visit是及物动词，选关系代词。

例： I vill never forget the days which I spent in the countryside. spend the days,spend 是及物动词，用关系代词。

例：this is the museum where the exhibition was held。 held the museum 不成立 ，只能是held in the
museum, held是不及物动词，所以选关系副词。

选1. pay a visit to 那儿可以填to which（介词后不能用that)，也可以填where, 但后面不能有to,因为where前不能有介词to.

选4,如果用where,就不要to.
