Which引导的非限制定语从句which作表语的例句

1、The meeting was put off, which was exactly what we wanted.

   which就是修饰前面的句子的，后面what引导的是表语从句，what在表语从句中做want的宾语

   which只能修饰先行词的说法是不对的

   which引导非限制性定语从句，一般情况下翻译为“这一点”，另外which不可以放在句首，这些就是与as引导的非限制性定语从句的区别了。

2、非限定性定语从句的作用是对所修饰的成分作进一步说明，通常是引导词和先行词之间用逗号隔开，将从句拿掉后其他部分仍可成立。

   which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分

   在引导限定性定语从句时，that有时相当于in which, at which, for which或at which

   Attitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed.

   I like the music for the very reason that(for which) he dislike it.

   我出于某种原因喜欢这种音乐，而他恰恰与我相反。

   We arrived the day that(on which) they left.
