The results of the company's cost-cutting measures are evident in its profits, which increased 5precent during the first months of this year after it fell over the last two years.
正确答案为：which have increased 5 precent during the first 3 months of this year after falling
其中有一个错误选项：with a 5 precent increase during the first 3 months of this year after falling 这个选项为啥是错的呢？？？困惑我很久的问题就是什么时候该用独立主格好一些，什么时候该用从句好一些呢？？？区分不出来呀，烦请大家明白的能够给解答一下！谢谢谢谢你们了！！

Heating-oil prices are expected to be higher this year than last because refiners are paving about $5 a barrel more for crud oil than they were last year.
正确答案为：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.
不明白的地方在于，原句哪里错呢？？怎么看出来需要用it做形式主语会好一些呢？？有时候我看到有的题目解析会说这种it形式主语wordy，想知道啥时候这种形式就wordy 什么时候又是正确的呢？？？

Although appearing less appetizing than most of their round and red supermarket cousins,heirloom tomatoes, grown from seeds saved during the previous year--they are often green and striped, or have plenty of bumps and bruises---heirlooms are more flavorful and thus in increasing demand.

正确选项为：Although heirloom tomatoes, grown from seeds saved during the previous year, appear less appetizing than most of their round and red supermarket cousins.
想问的就是为什么原句不对呢？？错误在哪里呢？? 还有一点困惑的地方在于第一个破折号之后的they指代的应该是heirloom tomatoes ，如果按照正确答案的来说的话，正确答案已cousins结尾，那么来说的话这个they岂不是会有指代的歧义？？？？知道的牛牛们帮忙解答一下吧感激不尽！！！

1题.with a 5 precent increase during the first 3 months of this year after falling,是独立名词结构，这里作状语，所以这里逻辑要和主句主语相一致，那么The results显然和 a 5 precent increase无法一致。所以这里 increase 只能作定语来修饰profits。

2题.这题，LZ答案错了，LZ标的正确选项是E选项,是错的,而原句是A选项才是正确的。这题，OG给的答案很模糊，这道题之所以不选E，是因为E把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都涵括为is expected，这种形式很好看，但句意上却大错特错，事实上只有heating-oil prices will rise higher this year than last year's才是expected，而后面的 because refiners pay about $5 a barrel for crude oil more than they did实际上是事实，是预测的依据，不需要expected，所以E选项错误。

3题，破折号部分句子对主句的补充说明，所以句首代词原则上也是指代主句主语，从句意上看也是指代主语heirloom tomatoes，因为cousins已经在前面用了round and red 作了充分修饰，所以这里they are often green and striped怎么也不可能是说cousins了。这题指代一点问题都没有，这题的主要错误在于句子结构混乱，让步状语从句部分都是修饰成分无主要部分。

1题还是不太明白这个The results 怎么和a 5 precent increase不一致了呢？？那以后看是用独立主格还是用从句就只能通过逻辑意思来判断吗？？具体的要怎样判断什么时候用独立什么时候用从句呢？？
3题可以再进一步解释一下什么叫让步状语从句没有主要成分呀？？

我的看法是

题1. 句子的结构是主句+分句 => the results are evident in its profits, which...
which引导非限定性定语从句，其先行词是profits, 从句谓语用复数，很清楚。那么为嘛不可以用with 呢？
逗号+with，一般是with 引导的独立主格作伴随状语，伴随前面主句。这里results 和 increase 逻辑有问题，results 怎么可以increase 和decrease呢，如果可以的话，那是不是应该把 "a" 给去掉呢？
举个例子： Mary was sitting near the fire, with her back towards the door.

题2. 坑爹啊，楼主。你说的正确答案，我怎么看，怎么不像。原因有2个。
第一. it is expected that 在gmat 里不是wordy吗？第二. 最伤的是，比较大大大大的不平行啊，this year 和 last year's不平行，because 后面倒是平行的。
后来查了下原题。不是答案都说是A吗，就是原句，楼主是不是哪里看错了。
但是问题在于，我觉得A也有问题啊。我觉得应该是 Heating-oil prices are expected to be higher this year than (heating-oil prices were) last (year), because......这里的助动词were 为什么不补出来呢？

题3. 我困了，明天看。。。

大家踊跃讨论，有问题请指教。谢谢！

GMAT机经考试难点之破折号的使用
破折号号基本分为两种：长破折（Dash）和  短破折（Hyphen）
其中的长破折号的用法又分两种：single dash  和  double dash
Hyphen 的用法很简单，是属于词语内部链接，比如 the 15-year-old girl 啊， the man-eater 啊之类的，表示单词内部的修饰，说明，强调等等。GMAT的SC中不太可能把这个设为考点。
但是Dash就不一样了，SC中经常遇到Dash的问题。
Single Dash：完全可以把其当做冒号（colon）,起到解释说明，强调，补充等等作用。比如：
Okay: Always buckle your seat belt; it's the law.   Stronger: Always buckle your seat belt—it’s the law.
Double Dash：可以把其当做括号（parenthesis），类似于插入语。很插入语一样，在实际操作的时候，是完全可以把double Dash连同中间的内容一起删除的。
经典题目分析： OG13-132
Although appearing less appetizing than most of their round and red supermarket cousins, heirloom tomatoes, grown from seeds saved during the previous year—they are often green and striped, or have plenty of bumps and bruises—heirlooms are more flavorful and thus in increasing demand.
(A) Although appearing less appetizing than most of their round and red supermarket cousins, heirloom tomatoes, grown from seeds saved during the previous year
(B) Although heirloom tomatoes, grown from seeds saved during the previous year, appear less appetizing than most of their round and red supermarket cousins
(C) Although they appear less appetizing than most of their round and red supermarket cousins, heirloom tomatoes, grown from seeds saved during the previous year
(D) Grown from seeds saved during the previous year, heirloom tomatoes appear less appetizing than most of their round and red supermarket cousins
(E) Heirloom tomatoes, grown from seeds saved during the previous year, although they appear less appetizing than most of their round and red supermarket cousins

如同插入语一样，在我们理解这句话的时候，可以把 —they are often green and striped,
or have plenty of bumps and bruises— 删去，这样原句就变成：
Although appearing less appetizing than most of their round and red supermarket cousins, heirloom tomatoes, grown from seeds saved during the previous year，heirlooms are moreflavorful and thus in increasing demand.
(A) Although appearing less appetizing than most of their round and red supermarket cousins, heirloom tomatoes, grown from seeds saved during the previous year
(B) Although heirloom tomatoes, grown from seeds saved during the previous year, appear less appetizing than most of their round and red supermarket cousins
(C) Although they appear less appetizing than most of their round and red supermarket cousins, heirloom tomatoes, grown from seeds saved during the previous year
(D) Grown from seeds saved during the previous year, heirloom tomatoes appear less appetizing than most of their round and red supermarket cousins
(E) Heirloom tomatoes, grown from seeds saved during the previous year, although they appear less appetizing than most of their round and red supermarket cousins
这样我们就发现这道题只能选B选项。
A的问题是heirloom tomatoes 和 heirlooms 是双主语。 C的问题也同样是。
D的问题还包括一个逻辑意思有歧义，让人误以为heirloom tomatoes appear less
appetizing的原因是因为它Grown from seeds saved during the previous year。此外D选项的单句连接处也有问题。
E的问题也是双主语的问题。

祝你好运~

楼上这个赞，大牛，就是觉得全解里面的这个题解释的有问题。去掉中间的分析就清晰了。感觉还是主语重复的问题最重要。
