英语中,带which的从句,有的前面加逗号,有的不加直接连接主句,有什么区别吗?

补充一些例子吧。比如 My mother praised me, which made me happy. 这里有逗号，那么which就指代My mother praised me这件事，整句就是妈妈表扬了我这件事让我很高兴。 Today I went to the Great Wall which was famous all over the world. 这里没有逗号，which指代the Great Wall 而不是Today I went to the Great Wall这件事，整句就是今天我去了长城，它在世界上很有名。 望采纳！
