网友回答
Programming languages,in puter science,are the artificial languages used to write a sequence of instructions (a puter program)that can be run by a puter.
主语programming languages,
定语in puter 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 puter 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 puter.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 puter是由that引导的定语从句修饰先行词instructions。in puter science介词短语作状语，也可以放在句子开头。
