求助！OG20 SC比较问题

Blair__Lu

下面两道题为列: 求问前后比较到底怎样看是年份对应还是主语对应
858. 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 hurting crops and therefore raisedcorn and soybean prices.（此题我选了C，因为我认为是now than a year ago这样，结果答案为B：因为比较对象为Price)


(A) than a year ago and are going down, even though floods in the Midwest and drought in the south are hurting crops and therefore raised

(B) than those of a year ago and are going down, even though floods in the Midwest and drought in the south are hurting 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 hurting 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 hurt 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 hurting crops and therefore raising






872. 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.
(这道题根据上一道题我认为是oil的Price比较，所以我选了E，结果又是this year和last year比较）

(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 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


我迷惑很久了这个类型的题，请问应该怎样确认比较对象呀，谢谢~~~

我的理解是比较有省略是可以接受的.
858的C price比较是没错的(OG解释错误)。Prices are higher now than (those of/they were) a year ago, 括号里省略不能作为直接排除的理由（比如872A就是对的）。排除的理由是 ",and are hurting crops"明显错误，本身是run on sentence, 整个句子结构也不合语法
872的E last year's的比较是错误的 - prices rise higher this year than (they did) last year, 可以省略they did, 省略后是last year不是last year's；还有it is expected that 强调语气没有用的必要

OG写解释的和出题的不是一批人，虽然大部分解释可以参考但有时解释比较牵强，这得自己判断。这两题就是最明显的一个inconsistency (我做的时候也发现了)

长丝弓

对于第858题，GmatLa的大神是这样分析的：
A选项：比较对象不对等。本题想比较的不是两个年份，而是两个年份的价格。检查本选项最合理的比较对象可知，我们真正应该比较的是“现在的价格”和“一年前的价格”。如果只用now，相当于比较的是“一年前的情况”和“现在的情况”，这是不对的。因为“价格的情况”和“价格”是不同的，只有价格才能higher（高低），价格的其它情况或者属性是没有高低之分的。

B选项：Correct. 本选项在逻辑和语法上均是正确的。

C选项：比较对象错误同(A)。

D选项：higher+than是习惯表达，不能加as。

E选项：本选项错误同(D)。

对于第872题，GmatLa的大神是这样分析的：
A选项：Correct. 本选项在语法和逻辑上均是正确的。比较对象是this year和last year，即，两个年份。

B选项：rise表达了“上升”的意思，而higher表示更高。在逻辑上，rise的结果一定是“使得某物higher”，因此，rise或higher只能存在一个，higher赘余；
另外，higher…than…是习惯用语，higher…over…是不正确的。

C选项：比较对象不对等。比较两个年份的价格在本题中也是可以的，但是，last year's在than的身前无法找到平行对象，可以改为： this year's heating-oil prices are higher than last year's prices.

D选项：higher…over…习惯用语错误同(B)。

E选项：比较对象错误同(C)；expect身后不能用宾语从句，而应该用不定式。这点考查了“不定式和从句的区别”。

谢谢你. 我明白了 prices 或者price to be与last year‘s是不平行的，但其实比较对象还是price （后者省略）
