标题: 发现一个RON和OG16冲突的地方，请反驳我

不同时间的比较是否到底应该补出Helping words。这个似乎存在矛盾，请看下述立场：

（1）Ron明确指出需要补充

more than ten times as much energy is generated through wind powernow as in 1990. Is this correct ?

No: because you needan explicit tense change. this is thepurpose for "...was the case" in the correct version here: it changesthe tense from "is generated"(present tense) to "was thecase" (in 1990). Ifyou don't have that explicit tense change, then the sentence is still talkingin the present tense (which is nonsense if you're referring to something thatwas true in 1990 and has since changed).

In no otherhistorical sighting did Halley’s comet cause such a worldwidesensation as (it did) in itsreturn of 1910-1911. No Problem,because there is no tense change.

more analogues:

i can run as fast on grass as on concrete
i can run as fast on grass as i can onconcrete
--> both correct (no tense change)

but...
i can run as fast now as in high school --> incorrect, since i'm not in high schoolanymore.
i can run as fast now as i could in high school --> correct, with the necessary tense change.

（2）OG16-90

Prices at the producer level are only1.3 percent higher now than a year ago andare going down, even though floods in the Midwest and drought in the South arehurting crops and therefore raised corn and soybean prices.
(A) than a year ago and are going down, even though floods in the Midwest anddrought in the South are hurting crops and therefore raised
(B) than those of ayear ago and are going down, even though floods in the Midwest and drought inthe South are hurting crops and therefore raising
(C) than a year ago and are going down, despite floods in the Midwest anddrought 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 theMidwest 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 Midwestand drought in the South, and are hurting crops and therefore raising

对于A的解释，OG这么说：AThe first part of this version of the sentenceillogically compares prices to a time; the second part of the sentenceindicates that a completed action (raised . . . prices) results from an ongoingpresent condition (floods . . . and drought . . . are hurting crops).

即：OG在这道题中的立场是，不应该这么比。（虽然没说要补出Helpingword）

（3）OG16-104

Heating-oil prices are expected to be higher this yearthan last because refiners are paying about $5 a barrel more for crude oil thanthey were last year.
(A) Heating-oil prices are expected to be higher this year thanlast because refiners are paying about $5 a barrel more for crude oilthan they were
(B) Heating-oil prices are expected to rise higher this year over last becauserefiners 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 lastyear’s because refiners are paying about $5 a barrel for crude oil more thanthey did
(D) It is the expectation that heating-oil prices will be higher for this yearover last because refiners are paying about $5 a barrel more for crude oil nowthan what they were
(E) It is expected that heating-oil prices will rise higher this year than lastyear’s because refiners pay about $5 a barrel for crude oil more than they did

这道题A正确答案里，确是Heating-oil prices are expected to be higher this year thanlast。没有补出因为时间改变的Helping words！！

请大牛指点，到底是否应该补出helping words。。。

Ron举例是说明动词的比较。

后面的两个例子一个是主语的比较，一个是状语的比较，所以就不用助动词了吧

这类比较词有个小规则比如"more...than..." 只要than后面的部分，能和more&than之间的部分找到平行即可
hope it helps

第一个句子排版有点乱，我回头再看。第二个句子没问题，因为它比较的是are expected to 后面的内容，而不定式是没有时态的，如果你要补出助动词，那就变成prices are expected to be higher than （prices were expected to be ）last year了。这是我的想法

作者: gmatf 时间: 2016-6-13 19:08
第一个a错了吧，因为是拿现在和过去比啊，要么补助动词，要么拿名词prices和those比较

刚想上CD来问这个问题（连题都一样）竟然就看到了。。同求解答，比较里到底应该是怎么个平行法，到底应该省略啥。。

作者: auspex 时间: 2016-6-13 22:45
我好好思考了一下觉得同意gmatf的看法，主要第三个问题的比较应该是to be的内容所以没有helping word的问题，are expected to并不是比较对象。虽然楼主已经和gmat分手，但还是对sc念念不忘…

另外，og90题我认为A就是错在了没有补充helping word，没有重复v来说明时态的不同，前半句如果写成Prices at the producer level are only1.3 percent higher now than they were a year ago就没问题了。b中通过those of巧妙地把比较对象变成了prices之间的比较，就如同a is higher than b（虽然有时间标志，但是这个时间标志是在those of里面的，成为了比较主体的一部分，所以不用补出were了）。ron的理论应该还是没错的。只是现在这题越来越tricky
