★★★★那要看关系代词在从句中的位置,是否跟在动词之后.如：
I like music which / that I can dance to.（which / that跟在动词dance后面,其实从句的意思是I can dance to which / that.）
I know a girl that / who likes singing and dancing.（that / who放在动词前面,其实从句的意思是that / who likes singing and dancing.）
其实,区分的方法很简单.你需要弄清的就是从句的句子成分,看如何才能让从句表达的意思完整、清晰,从而分辨作的是主语还是宾语.★★★★
