The two major languages spoken in what is now called Great Britain before 1066 were Celtic and Old English 公元1066年之前，在如今被称为大不列颠的地方有两种主要语言：CELTIC和 OLD ENGLISH. 主句：the two major languages were celtic and old english. "spoken in what is now called great britain before 1066"在句中做定语修饰the two major languages

首先，这句句子的主体结构是The two major languages were Celtic and Old English. 而spoken in what is now called Great Britain before 1066 是languages的定语从句，其中又有一个宾语从句what is now called Great Britain before 1066，意思是在1066年以前，在现在被称为“英国”的这个地方。整句话的意思是：在1066年以前，在现在被称为“英国”的这个地方，人们使用的两种最主要的语言是凯尔特语和古英语。
