英语句子成分分析，急！谢谢谢谢！
doctor advises him to.这个to是拿来做什么成分的？还有这三句话，三句都是原主句的从句部分改了一下，不确定他们的成分，请指导一下，谢谢谢谢，急！！！all of which can be turned into useful things under certain condition.he is willing to take on another assignment.why he refused to help us？
doctor advises him to to用来做不定式成分
all of which can be turned into useful things under certain condition
which后是定语，under后是状语，all省略前文代指的东西，即主语，of修饰名词所有格
he is willing to take on another assignment.
he是主语，is即为谓语，be willing to do愿意做某事，another修饰assignment，assignment是宾语
why he refused to help us？
这句话应该是从句，由疑问词引导的从句，后面应该使用陈述句式，原句为 why did he refuse to help us?
he 是主语，refused 是谓语，to help表动词不定式，us 为宾语
