Is this the museum ____you visited the airplanes last week Is this the museum____you visited last

1.Is this the museum __where_/ in which_you visited the airplanes last week
这里是问,这个是不是你上周在里面参观了飞机展的那个博物馆?
因为you visited the airplanes 是一个完整的句子,所以只能由where 来引导一个定语从句,来修饰museum,从句可以还原成you visited the airplanes in sp.（some place,某个地方）
2.Is this the museum__which/ that/或者不填__you visited last week
这里因为you visited后面缺了宾语,所以可以由which 或者that来引导定语从句,which/that在从句当中充当宾语成分
这种题型还是比较经典的,经常都在visit这做文章,主要还是要看后面的这从句,成分是否完整了,如果缺少了宾语就用which/that,如果已经是完整句子就用where或in which,一般情况下是这样.
