以here或there开头的句子,常常需要倒装,如：Here comes the bus.There goes the bell.这两个句子这样倒装,是因为主语是名词.如果主语是代词,只能用你所说的后一种用法,也就是Here she comes和Here it is.
另：你所说的主语做代词,应该是：主语是代词.即上述句子中的she和it当主语.Here comes the bus的主语是Here吗？所谓的倒装，here就是。这句话正常的顺序是：The bus comes here.主语是the bus，谓语是comes, here是表示方向、方位的状语。同理：Here she comes,主语是He, 谓语是comes, 状语是here.所以Here comes the bus的主语到底是不是Here。。。已经回答，请认真看上面的回答!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!The bus comes here=Here comes the bus!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
