with which 引导的什么从句

which可以引导宾语从句。which和what在宾语从句中同属连接代词，在从句中可做主语、宾语及定语。它们们二者最主要的区别在于本身意义的不同，which翻译成“哪个/件/条”；what翻译成“什么”。

(2) 当先行词前面有only, some, any, no, every, little, few, much, all, very等形容词修饰时，只能用that。

(3) 当先行词由形容词的最高级或序数词修饰时，只能用that。如

(4) 当先行词同时包括人和物时，只能用that。如

Luxun and his works that we are familiar with are considered great. 人们认为我们所熟识的鲁迅及其作品都很伟大。

(5) 当先行词在定语从句中作表语时，只能用that。如

(6) 当主句是以 which 开头的特殊疑问句时，只能用 that。如
