Question

this museum is__you visited the other day?a.that b.which c.in which d.in that

this is the museum___we saw an exhibition the other day.可以填where么，因为我们在那里看展览，是地点状语。
this is the museum___you saw the other day.有 that， where， in which ，in that。可以选 that么？是定语从句。

Answer 1

1 Is this museum _THE ONE (THAT / WHICH )_you visited the other day ?
THAT / WHICH 是visited的宾语。the one是this museum的表语
2 This is the museum__WHERE _we saw an exhibition the other day.
WHERE== in which == in the museum，是 saw an exhibition 的地点状语。

Answer 2

第一个句子是填where
下一个必须选that 因为后面的定语从句缺一个名词性的东西，只有that可以充当名词
