At times, I turn on the television and just leave it to chatter in the background, something that'd never done previously.
译文:有时,我打开电视仅仅是要一种氛围,这是我以前未做过的。
我的疑问:something that'd never done previously. 作这个句子的什么成分?请老师指教,谢谢!
此处 something 是 background 的同位语, 紧跟其后的 that'd never done previously 是定语从句,修饰先行词 something,that'd 根据惯用法是输入时手误吧,应该改为that I'd ,值得注意的是定语从句与同位语从句的区别,例如:
① The news that you told me yesterday was really exciting.你昨天告诉我的那个消息真的很令人激动。(定语从句)
② We heard the news that our team had won.我们听到了我们队获胜的消息。(同位语从句)
