My classmate found a bag in the P. E. class today. We have discussed whose① bag this might be. Some students think it may belong to Mary. But I think it must belong to② Kathy because she likes Jay Chou very much and there is a photo of him in the bag. But Mary likes Jackie Chan very much. Kathy has long hair, and there is a hair band in the bag. Mary has short hair, so she doesn’t need a hair band. And there is also a credit card. John has even seen Kathy use③ the credit card, Then, it must be Kathy’s bag because she is the only④ person who has a credit card in our class.
①discussed whose..引出对物品归属的推测。

③even seen Kathy use…进一步推测物品可能属于Kathy。
④must be Kathy’s...the only…表示最终确定物品归属。
