可以啊,这个叫做分裂定语从句.
he is the only person in our office who is invited to the meeting .
先行词person和引导词who被in the office隔开了,引导词必用who.还有没有其他句子中的成分能介于二者之间的？he is the only person in our office who is invited to the meeting 这句话倘若in the office放最后，那么who还可以用谁代替？拜托了。。。。。。。。。。。。。。。。。。。。介宾短语定语，ing分词短语定语，ed分词短语定语都可以在后面隔开。若in the office放在后面去，因为先行词前有only修饰，则通常用that.不用who.He is the only person that is invited to the meeting in our office.
