Heating-oil prices are expected to be higher this year than last because refiners are paying about $5 a barrel more for crude oil than they were
查阅了og的解释,The sentence connects acomparison between this year's and last year's heating-oil prices with a comparison between this year's and last year's crude-oil prices.
个人认为关于这里的两个比较,第一个比较其实是省略了they were , 表示一种状态的可以省略,因为是be higher,而后面的paying 是一种动作,所以不省略they were,个人愚见。。
求大NN们解释,这题翻遍了都没有看到让我觉得很理解的解释,虽然看到了两个平行结构,但仍有两个问题:一、Heating-oil prices are expected to be higher this year than last——last 后面为什么可以省略?
二、refiners are paying about $5 a barrel more for crude oil than they were——more为什么放在barrel后面,为什么可不可以是paying about $5 more for a barrel of crude oil? 求教more的知识点。
