正确答案是这样 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 last year.
这句话中比较的形式是 prices this year (are) higher than last (year) last后省略的是时间 比较的主体也是时间?一般感觉应该是说price of this year is higher than that of last year的啊 所以这个表达究竟是个什么情况?
你自己提供的这个句子"The price of this year is higher than that of last year“比较的是主语,两年的价格作比较,但原文"The price is higher this year than last year." 比较的是时间状语,今年和去年比。这两种句子的写法都对,只是看比较什么成分罢了,呵呵
