有关英语语法的问题

答案如下图

1. Is this museum the one you visited a few days ago?

   这题考查是主谓宾结构和定语从句的知识。

   我们先把这个句子变成肯定句，便于理解：

   This museum is the one (that) you visited a few days ago.

   the one 既当主句中的宾语，又当 (that) you visited a few days ago 定语从句的先行词， that在从句中当宾语，可以省略。其他三个选项都不行。

2. Is this the museum where the exhibition was held?

   这题考查是定语从句和地点介词的用法。

   我们先把这个句子变成肯定句，便于理解：

   This is the museum where the exibition was held.

   the museum 是主句的宾语，又是定语从句where the exibition was held的先行词。

   定语从句中主语是the exhibition was held 后面缺一个状语，所以that 和 the one 都不能当连接词，where可以当连接词，在从句中当地点状语；on which 错了是因为，at the museum的搭配，所以，如果on which 改为 at which就可以了。
