标题: 对于OG12TH 93比较的一点看法，然后还有一个知识点不懂，求解答！
Heating-oil prices are expected to be higher this year than last because refiners are paving about S5 a barrel more for crude oil than thev 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

这题有争议的还是AE选项，个人看了搜索了很多帖子，然后很多N人都总结什么状语还主谓比较神马的，看到我一头雾水，我看了一下句子，突然个人认为E选项有点歧义，但是OG貌似没有说出来
就针对比较而言，很清晰的句意就是今年的油比去年的高
然后E选项歧义就出来了，than last year’s （will）好了，如果这句是省略了will，就改变了句子的意思了，变成今年油价上涨的幅度会比去年油价上涨的幅度要高，但是如果没有will，就可以表示出今年的油比去年高了。。。。然后我个人有个知识点不是很清楚，为什么句末是last year不是应该用一个一般过去时么？怎么来了个they were。。。搜索了好久帖子都没看见，求NN们回答

楼主，我这样分析，你看行不行
(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

这里heating-oil prices will rise higher this year中，heating-oil prices是主语，will rise是谓语，higher是状语，然后this year是时间状语。这是than前面的一部分。

而后句中的只有last year's，你觉得这是省略了什么呢？按照你的话补完的话，last year's prices will rise，对吧。

那么按照比较前后的平行，这句话就不如A平行。如果要平行的话，也应该是，主语对主语，谓语对谓语，状语对状语，变成prices would rise last year。

还有就是你说的歧义的问题，我觉得之所以会有歧义不是因为will的省略的问题，而是结构不平行的问题。如果是this year’s prices will rise higher than last year’s，那么即使不出现will也不会有歧义，因为动词后面没有宾语，只是单纯的主谓结构。举个例子：

I eat faster than you. 就不用写成 I eat faster than you do. 因为不会引起歧义，只是单纯的主谓结构。
而 I eat more apple than you do. 就不能省略do，因为会让人误解成“比起吃你，我吃了更多的苹果”这样。这句话有宾语，所以要考虑歧义的问题。

最后，你说的A的they were的问题，是省略了paying。

refiners are paying about $5 a barrel more for crude oil than they were (paying) last year.

不是一个完美的平行么。than以前用现在进行时，than以后因为是last year，所以用过去进行时。

这题还有一点是Rhretorical construction的问题，我当时错选了B，B的解释里面：
the comparative terms more than should immediately follow $5 a barrel.

选项E也存在这个问题。
Manhattan书里面也提到特别注意more这些adverb/adjective的位置问题。逻辑上，
paying about $5 a barrel more for crude oil than ... 这里more修饰about $5 a barrel，非常accurate
而
paying about $5 a barrel for crude oil more than ...这里more修饰前面整个"paying .... for crude oil"，即paying more，既可以表示单价提高导致总花费提高，也可以表示“单价既定为about $5 a barrel，而多付一些钱——也就是多买一些商品”，这就造成了逻辑上的ambiguity.

我觉得这题还有redundancy的问题
will be higher
will rise
这两个对，但是不能will rise higher
rise和higher意思重复。或者说，逻辑上如果用到rise higher，那就是说增幅的增加，而非它本身的增加，这种一般用higher increase来表示增幅的增加。

顶楼上童鞋，那个more than我还真没看出来~粗心！

受教了~

但我想问一下baby MM，像这种几乎全句都是划线的题，我们一般的做法是逐项排除，最后选出最好的选项（至少这是我从Prinston上学的的方法）。
但是这样的方法导致这一题可能要做比较长的时间，我大概花了2分钟。

所以我想问一下，一般做这种题还有没有其他的技巧？如果没有，怎么能够控制时间呢？

“我们一般的做法是逐项排除，最后选出最好的选项（至少这是我从Prinston上学的的方法）”
这种方法在考场上肯定要不得
看看stacey@Manhattan的贴子吧，教我们怎么从整体把握，我的日记贴里面有
我现在反倒觉得长划线题最简单，因为从宏观上基本就能迅速瞄准正确选项，而不需要深入微观，也不需要排除法。

作者: babybearmm 时间: 2012-3-4 15:26
比如这题，读完A选项理解句意，宏观上，A没问题，should be as it is.
什么"Expectations are ..." 或者 "It is ..." 看着就不爽，速度排除，句子主干肯定是A那样，或者类似的B。然后再深入微观，就把A/B不同的地方进行比较，A更好。

……实在不好意思，我还是没太看懂more的用法~~A选项中为什么要把more放在这个位置呢？他的意思是说每桶比原来多了5$么？E那种说法为什么不可以呢，可以理解为他们今年每桶花5美元，比去年每桶花得多……求指教！另外关于more 的还有og后面的94题，有关飞机晚点的问题，正选：55% increase in delays, 错选：55% more delay. 说后者修饰不清晰，为什么呢？O(∩_∩)O谢谢

(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
注意这里明确说: "pay about $5 a barrel for crude oil"，就说目前约"$5 per barrel"这个价，然后补充说more than they did
而原文不是这个意思，是说多付了$5 per barrell. 所以就必须像A那么表达。

55% increase in delays: 本来有100次delays，现在有155次delays
55% more delay，可以有这样的歧义理解：本来delay了100分钟，现在delay了155分钟，就说"55% more"指的是delay的程度

为什么呢？我反而觉得It is...这种形式主语引出正好可以避免头重脚轻的句子，可是OG却说它Itis expected that... is wordy and awkward

另外还有一个问题，就是D的解释里说，for and what are unnecessary.
D说about $5 a barrel more for crude oil now than what they were
可是正确答案A说about $5 a barrel more for crude oil than they were

这两个句子都有for啊，是不是OG写错了？

作者: jiaoguitar 时间: 2012-6-29 12:37
楼上，it is引导强调句是GMAT的考点之一，并非it is开头就一定是错的。但这里it is expected开头却导致了句子的歧义。原文说的expect的对象是heating oli prices；如果用it is expected开头，expect的对象变成了整句话，所以OG会说awkward。

D选项说for是unnecessary，指的是for this year的for；不是指 for crude oil的这个for。OG是GMAT的圣经，它是不会错的。。。

作者: MiaZhang 时间: 2012-10-18 09:40
其实这个题，排除E就是看的状语比较。
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

higher...than...

先看than后面结构前面是否有出现过。than后面是last year's，显然前面没有出现，即使是省略，也要有相同结构才行，要么就补出that。
举个例子（可能在所有格上有点问题，明白意思就好~）
ZhaoWei's eyes are bigger than LinYilian's. 绝对正确，前后都是所有格's结构，省略的名词清晰，LY's后面省略了eyes
ZhaoWei's eyes are bigger than those of LinYilian. 在GMAT很多题中也是正确的，those指代eyes
The eyes of ZW is bigger than LYL's. 这个就有点问题了。
个人感觉，比较也是一种平行，讲求结构上的对称，而且省略的名词一定要清晰

其次，这个题本身是拿去年和今年的情况比较，last year 在前半句是做状语，后面的this year也应该做状语，不应该用所有格
