The strength of a household's kinship ties is a more reliable indicator of that household's receptivity to new agricultural technologies than is its quantity of nonland wealth.
句中的is是倒装吗?应该是这样是不是:
The strength of a household's kinship ties is a more reliable indicator of that household's receptivity to new agricultural technologies than its quantity of nonland wealth is.
这个句子本来是The strength of a household's kinship ties is a more reliable indicator of that household's receptivity to new agricultural technologies than its quantity of nonland wealth.记得XDF语法老师说,助动词的补出只要求时态、语态正确,对位子没有要求。
