OG: The sentence as written makes an illogical comparison between prices at the producer level and a time period ( a year ago); surely the intended comparison is between such prices now and those of a year ago. 答案：B
772. Heating-oil prices are expected to be higherthis year than last because refiners are paving about S5 a barrel more forcrude oil than they were last year. A. 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 B. Heating-oil prices are expected to rise higher this year over last because refiners pay about $5 a barrel for crude oil more than they did C. Expectations are for heating-oil prices to be higher this year than last year's because refiners are paying about $5 a barrel for crude oil more than they did D. It is the expectation that heating-oil prices will be higher for this year over last because refiners are paying about $5 a barrel more for crude oil now than what they were E. It is expected that heating-oil prices will rise higher this year than last year's because refiners pay about $5 a barrel for crude oil more than they did
OG: the sentence connects a comparison between this year's and last year's heating-oil prices with a comparison between this year's and last year's crude-oild prices. 答案：A
想讨论下两题中的比较，因为在我看来两题中的比较用的是同一个结构，都是想要比较this year's price vs last year's price，并且句型结构也都是prices are higher now/this year than a year ago/last。那么为什么758里 than a year ago 就被列为是错误的一个原因，会导致illogical comparison，而772中即使OG指出是this year's price和last year's price比较，却可以用higher this year than last？ 谢谢！ |
