this is little tonny,who i think has done very well though ,he is so young
问题描述：
this is little tonny,who i think has done very well though ,he is so young
怎么知道I THINK 是插入语,为什么是WHO而不是WHOM?
答
1.请看这句话：
This is little tonny,who has done very well though,he is so young.
其中去掉了插入语“I think”,但是句子仍然成立,只不过变成了客观的叙述：“这是小托尼,虽然他很年轻,但他做得很好.”
而原句的意思是：“这是小托尼,虽然他很年轻,但我想他做得很好.”这是主观陈述句.
2.在这个从句中,who是作为has done very well的主语,而whom是who的宾格形式.
