(转 存档)这题我扒了国内国外很多解释,最后还是同意RON解释的。
RON觉得,“Heating-oil prices are expected to be higher this year than last”跟“Prices at the producer level are only 1.3 percent higher now than a year ago”,都是省略了(they were),省略了之后 aren't necessarily faulty,也就是省略不省略都可以接受。比较对象是两个时间段的价格,但不是 those of last year,因为要跟前面的句式保持平行,所以是they were。
比前年的价格多了5 元 5 yuan more than the prices were last year
中位数和右边的数可以相等的
