"An artist who seeks fame is like a dog chasing his own tail who,when he captures it,does not know what else to do but to continue chasing it."中第二个who在句中是什么成分?
答
when he captures it 在这里可以看作是个插入语 插入语可以省略 然后你看句子就知道who是什么成分了去掉who貌似也是个完整的句子，跪求解？去掉第二个who？是我觉得主句是An artist does not know what else to do but tocontinue chasing it.不需要who在我看来，第二个who应该指代的是前面句子中的dog恍然大悟，thanks其实我也看了半天 突然就想通了 不用谢～
