OG17 758和OG17 772
758: Prices at the producer level are only 1.3 percent higher now than a year ago and are going down, even though floods in the Midwest and drought in the South are hunting crops and therefore raised corn and soy bean prices.
A.
B.than those of a year ago and are going down, even though floods in the Midwest and drought in the South are hunting crops and therefore raising
C.than a year ago and are going down, despite floods in the Midwest and drought in the South, and are hunting crops and therefore raising
D.as those of a year ago and are going down, even though floods in the Midwest and drought in the South are hunting crops and therefore raise
E.as they were a year ago and are going down, despite floods in the Midwest and drought in the South, and are hunting crops and therefore raising
OG解释A选项中的比较为什么错了的原因时,是说A选项将price与a year ago进行比较,原话是:the first part of this version of sentence illogically compares prices to a time.
772: 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.
A.
B.Heating-oil prices are expected to be higher this year over last because refiners are paying 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 are paying about $5 a barrel for crude oil more than they did
OG解释A是对的,比较的对象也没有问题。但是问题是772中的A选项与758中的A选项结构基本上是一样的:
558:Prices at the producer level are only 1.3 percent higher now than a year ago
772:Heating-oil prices are expected to be higher this year than last
为什么这两个题的比较中,558就是price与time在比较,而772却是正确的比较。
