看哪个句子正确?为什么?1,it is a social music that per
formed at weddings,birthday parties and feasts.
2,it is a social music,performed at weddings birthday parties and feasts.
请告诉我另一个为什么错了?

Answer 1

2.it is a social music performed at weddings,birthday parties and feasts.
此句没错,music后面的逗号（,）应去掉.performed .为过去分词短语,作后置定语,修饰前面的music.
1.it is a social music that performed at weddings,birthday parties and feasts.此句不妥.music之后多了一个that.加上that后,就成了定语从句,意思是music自己在perform自己.music是被演出的.应使用被动态.如果把that后面加上is,也就可以了：
it is a social music that is performed at weddings,birthday parties and feasts.
