758. 迷惑原因：parallel+语义

Prices at the producer level are only 1.3percent higher now than ayear ago and are going down, even though floods in the Midwestand drought in the South are hurting crops and therefore raised corn andsoybean prices.

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

(B) than those of a year ago and are goingdown, even though floods in the Midwest and drought in the South are hurtingcrops 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 cropsand therefore raising

(D) as those of a year ago and are goingdown, even though floods in the Midwest and drought in the South hurt crops andtherefore raise

(E) as they were a year ago and are goingdown, despite floods in the Midwest and drought in the South, and are hurtingcrops and therefore raising

Herl大神的解释：

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和a year ago，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。

772. 错误原因：Parallel

Heating-oil prices are expected to behigher this year than lastbecause refiners arepaying about $5 a barrel more for crude oil than they were last year.

(A)Heating-oil prices are expected to be higher this year than last becauserefiners are paying about $5a barrel more for crude oil than they were

(B) Heating-oil prices are expected to risehigher this year over last because refiners pay about $5 a barrel for crude oilmore than they did

(C) Expectations are for heating-oil pricesto be higher this year than last year’s because refiners are paying about $5 abarrel for crude oil more than they did

(D) It is the expectation that heating-oilprices 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 thatheating-oil prices will rise higher this year than last year’s because refinerspay about $5 a barrel for crude oil more than they did

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。

我的疑惑：

Prices at the producer level are only 1.3 percent higher now than a year ago 可简化为：

1. Prices are 1.3 percent higher now than a year ago

Heating-oil prices are expected to be higher this year than last 可简化为：

2. Prices will be higher this year than last

我觉得1和2两个句子的结构没有什么区别呀，语义上也没什么不同，为什么1就错了，不能时间直接相比较，而2就是对的呢？

A選項：Prices at the producer level are only 1.3 percent higher now than a year ago 沒有錯誤, 錯的是後面hurting and raised不平行
