wholesale prices in july rose more sharply than expected and at a faster rate than consumer prices,
问题描述：
wholesale prices in july rose more sharply than expected and at a faster rate than consumer prices,
这句话中at a faster rate than consumer prices 是作什么成分?它的主语是什么?at 开始应该是一个介词短语吧?中间的and是一个连词吗,怎么后一句与前一句关系不太明确呢?有谁能从语法的角度帮我解释一下吗?
答
Wholesale prices in July => 主语,7月份的批发价格
rose => 谓语动词,
more sharply than expected 状语 1
at a faster rate than consumer prices 状语 2
两句状语用 and 相连结.是什么状语?不是宾语吗?两句都是修饰动词 rose 的状语。
