其实,这里since when要表明的是一段时间的概念,而since which 只是一个点的时间概念.看看后面的句子,这种改变并不是一蹴而就的.是需要经过一段时间的积累的.所以,when,指代的是1946及以后的一段时间,而并是单单的1946.
时间状语从句。。因为是在那一年education system发生了巨大变化,而不是那本书发生了巨大变化
是这样的,用which,指“the book was written in 1946”这件事了,而句子是为了强调那个时间点
时间状语从句。。因为是在那一年education system发生了巨大变化,而不是那本书发生了巨大变化
因为时间状语从句用when来引导,所以用since when。地点状语从句用where来引导,例如from where。
