are you sure you want to part with this?are you sure you want to part of tihis?两句哪个对?

题目

are you sure you want to part with this?are you sure you want to part of tihis?两句哪个对?
假设都对
如果不对为什么

答案

part with 失去,卖掉〔付出〕…; 与…分开
part of 部分
are you sure you want to part with this?
你确定你要卖掉这个东西?
另外一句是错误的.
part
n.部分；零件；作用；角色
vt.使分裂；拆移；使分开
vi.分开；分离；分岔
part作为动词的时候,组成的介词短语是part with.
part作为名词的时候,组成的介词短语是part of.
根据句子意思,和句子的成分分析.肯定是第一句话是对的,另外一句是错的.
