关系代词/关系副词1.Is this museum __D_ you visited a few days age?A.

1.Is this museum __D_ you visited a few days age?
A.where B.that C.on which D.the one
the one 在这里是先行词,后面省略了 that.从这句子的陈述句可以看出来
This museum is the one that you visited a few days ago.
2.Is this the museum __A__ the exhibition was held.
A.where B.that C.on which D.the one
the museum 在这里表示地点,用关系副词 where.

1. 这个句子缺少表语.所以选 D.
The one = 表特指 you visited a few days age那个museum
2. where（也可以用in which). 这个是一个状语从句
遇到类似题目可以吧句子改成陈述句来分析
Eg.
1.This museum is __ you visited a few days age.

1 this museum is 肯定后面的选the one 了因为museum 是有修饰词的this museum后面要 用个代词表示同一个东西用 the one了在后面是个定语从句省略了that
2this is the museum 后面是个定语从句缺少状语所以是where

1.选D
2.选A
做这种题目，要懂得把从句当作主句来考虑。
如：You visited this museum a few days ago.第一句什么都不缺，用the one来指代this museum，that被省略。

1.B
2.A
1.是that引导的定语从句，修饰museum
2.陈述句序为：this is the museum where……这里是where引导的状语从句，where在后面的从句中做状语。
