答
A bithday gift bought for you,I had been invented.我也不知道我的对不对，但至少这个是独立主格结构 。前后主语不一致，有没有连词，这是独立主格结构的特征。
答
因为：If i had been invited to your birthday party,i would have bought a birthday gift for you. 这个句子是一个虚拟语气，意思是：如果我收到
答
原句是虚拟 并未发生 而你改完的句子则表示被邀请是既定的事实 这句话可以改成同义句：Had been invited to your …… 似乎改不了独立主格
