定语从句,先行词是狗dog时,引导词有两种情况: 1. 用that或者which,比如The dog which has a bad leg is Tom's. (有条腿坏了的狗是汤姆的) 2. 因为人们喜欢狗,或者童话里,拟人化,用who,比如A dog who is popular(一只受欢迎的狗)。
回答如下: 在定语从句中,当先行词为动物名词时,关系代词可用which,that,whose; 若对动物拟人化,也可以who,whom。动物的代词可以用it,its,itself; 动物名词拟人化时,也可以用he,she,him,her, his,hers,himself,herself。例如: The tigers which / that killed the keeper / breeder have been shot to death. She raises a little dog, who brings her happiness. When I watch TV, my cute cat often curls herself / itself up on the sofa. The cat which / who / that is licking its / his hair is mine.
