请帮我分析这句话的成分,有几个从句包括其中Programming languages,in comp

Programming languages,in computer science,are the artificial languages used to write a sequence of instructions (a computer program)that can be run by a computer.主语programming languages,定语in computer science谓语are补语the artificial language后置定语（ed分词短语作定语）used to write a sequence of instructions(a computer program)这个定语是表示被动用法,被用来编写程序的.所以用ed分词原句是定语从句(which is used to write .)实际运用中,which is常被省略只有一个定语从句that can be run by a computer.先行词是instructions======以下答案可供参考======供参考答案1:句子的主干是Programming languages are the artificial languages。used to write a sequence of instructions 是过去分词作后置定语，修饰前面的名词languages ，that can be run by a computer是由that引导的定语从句修饰先行词instructions。in computer science介词短语作状语，也可以放在句子开头。
