who引导的定语从句是直接修饰the person 的,表示受伤的人
that引导的从句其实是feel的宾语,表示感觉到什么
而 feeling that he should be apologizing for his bad behavior in expecting an apology 这一整句也是修饰the person 的
感觉还是怪怪的,改一下
the person who has been injured felt that he should be apologizing for his bad behavior in expecting an apology.
这一句可以这样翻译:
受伤的人感觉到他应该为在要求别人道歉时作出的恶劣行为而道歉
你少打了一个词吧 leaves the person
还有主语呢?句子都不完整!加上主语,后面是定语从句
