hear is a story share with you 还是 here is a story i wanna share with you?那个对?

here is a story i wanna share with you

后者是对的
here is a story which shared with you 才可以
你的第一句中,少了一个替代词

是Here，解释为，这有一个故事我想和你一起分享．

here is a story i wanna share with you
这是一个我想和你分享的故事
HEAR是听说的意思 HERE是这里的意思

我也认为是后者,因为share with you相当于是一个定语从句修饰story,省去that,而story是被分享,应用被动语态shared,所以这里用错了．后者也是i wanna share with you定语从句,结构正确
