帮忙看两句英语句子的语法
1.Pete Rose,the famous baseball player,whom I have never met ,taught me something so valuable that changed my life.
"the famous baseball player"在句子中是什么成分?“whom I have never met ”是非限定性定语从句吗?whom是作宾语?“so valuable that changed my life”这句怎么突然冒出来了?定语从句修饰SOMETHING?
2.I changed my attitude to one of positive expectation,书本的翻译是：我改变了自己的人生态度,我的期望变得更加积极了.这里是不是有个短语,change sth to sth?“one of positive expectation”这里就更不明白了
