怎样区分介词短语是修饰名词还是修饰动词？

Question

怎样区分介词短语是修饰名词还是修饰动词？He's working for Mr. Wang in the kitchen. 意思是“他在厨房里为王先生做事”还是“他为厨房里的王先生做事”？ 怎么判断是后者还是前者呢？

Answer 1

介词短语作定语时，一定在名词之后。如： the people in the room房间里的人。He's working for Mr. Wang in the kitchen. Mr Wang in the kitchen is my boss.
介词短语作状语修饰动词时，可以置于句首，句尾。如: In the kitchen he is working for Mr Wang. He's working for Mr. Wang in the kitchen.
综上所述可知，He's working for Mr. Wang in the kitchen 是个歧义句。它有两个意思：1. 他在厨房里为王先生做事。2. 他为厨房里的王先生做事。
消除歧义的方法就是：作状语时，把介词短语置于句首（In the kitchen he is working for Mr Wang. ）；作定语时，一定要置于名词之后。也可以用定语从句（He's working for Mr. Wang who is in the kitchen. ）追问

这句话是不是就是个病句了？，高考会出现这样的话吗
