Dont get me wrong! its just that you seem so young and already doing business overseas.
请问这里为何用doing ，既然前面是and 按理说doing 应该和前面某个词并列，前文已经说过她在国外做买卖，所以做seem的补语和so young并列好像不太合理，请问该如何理解呢？
seem 一般后接不定式否成复合谓语。假如不定式为系词to be, 而表语为归属性表语时，to be常可以省略。此时seem则被剖析为系词，后接表语。但大家要了解seem作为系词，只能后接归属性表语，不可以后接确认性表语。比如：
可以说 He seems tired. = He seems to be tired.
但不能说 He seems Tom. 应改为He seems to be Tom.
由此可知，seem是不能后接目前分词短语的。所以本句中的doing为语法错误。应改为不定式结构。
Dont get me wrong！ Its just that you seem to be so young and already to be doing business overseas.
