谁能来帮忙分析一下这个句子?
Manyarguethatthecostsofglobalizationaretoohighandthatdifferencesbetweencountriesandcommunitiesneedtobemaintainedbeforewequicklyandcompletelyloseallsenseofwhoweare,wherewecamefromandwhatchoicesarestillavailabletous.
其中differences在这里是动词还是名词needto的主语是谁?为什么是wherewecamefrom而不是comefrom?
何雨果回答：
这句话的主干是Many(主语)argue(谓语)thatthecostsaretoohigh(宾语从句)and(连词)thatdifferencesneedtobemaintained(宾语从句).
在宾语从句thecostsaretoohigh中,costs是主语,are是谓语,high是表语；在宾语从句differencesneedtobemaintained中,differences是主语,needtobemaintained是谓语.
beforewequicklyandcompletelyloseallsenseofwhoweare,wherewecamefromandwhatchoicesarestillavailabletous是介词结构作状语,修饰动词结构needtobemaintained.在这个介词结构中,we是主语,lose是谓语,sense是宾语,ofwhoweare,wherewecamefromandwhatchoicesarestillavailabletous是介词结构作sense的定语.
在whoweare,wherewecamefromandwhatchoicesarestillavailabletous中,两个are都是现在情况,而came却是已经发生了的情况,即我们的到来是过去发生的事.
