【Thanks your kind.
I have made correction, changed [because] to [the reason is that].
BTW, I am learning English】
①过去分词changed 带的过去分词短语【changed [because] to [the reason is that].】,这个过去分词短语是前句【I have made correction, 】的补足语。而【and】是代表两个并列句,这里不便使用。
②因为提问中有两个单词【why】和【because】,如果用单数代词【it】,不能指明代表哪一个。所以不能用【it】。
③【Thanks you kind】是笔误,应该是【Thanks your kind】,是口语,省略了【for】。【"Thanks for your kindness.】是正规语。
BTW,谢谢你。
