Question

I have never been to Beijing ,but it is the place--

A where i would like to visit B in which i would like to visit
C i most want to visit D that i want to visit it most

Answer 1

C

选先行词，看先行词在从句中起什么作有、充当什么句子成份
A where i would like to visit 先行词在从句中应作visit的宾语，where是个副词不对，副词不好作宾语的，应该是which i would like to visit
B in which i would like to visit 理由同上，其实in which=where，所以这个选项仍是错的
D that i want to visit it most 从句中有宾语了it，再有个先行词，重复了，语法上有问题，也不对

C that/which都可以省略不用，所以这句是对的

Answer 2

C 先行词BEIJING 在定语从句中作VISIT的宾语,可省略
