不是说如果先行词做表语，关系代词就只能用that,不能用which吗?
这里的book是不是做表语啊？

book做主语，相当于 a book introduces China in detail
看出你的问题在哪了，先行词做什么成份是看他在从句中的作用，不是主句

用that which都可以，用that表强调句

不是表语，是主语。it 是先行词，真正的主语是book

It's a book which introduces China in detail. 'It's a Chinese book.'哪错了 it's a party 求歌曲！！！duke of earl / book of love / get a job / good night, it's time to go It's a cake.这是什么意思？ It's a deal什么意思？ it's a small world it's a rainy day韩文歌 It's a hard life It's dark Miss a go.
