OG13 132题我认为比较好的解题思路（放上来给大家看看）

叶晴豆

我觉得132题出的真心不错，OG的解释中提到了很多点，看了半天觉得神乎其神，不知道它到底想考察个什么玩意儿。
直到我看见beatgmat上一个慈祥叔叔神乎其神的解释。
原题在此 #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

大叔叔的解释：http://www.beatthegmat.com/og-13-132-t168495.html
The dashed portion (not underlined) is a PARENTHETICAL THOUGHT.
A parenthetical thought is not necessary; it can be removed without changing the core meaning of the sentence.
Combine each answer choice with the rest of the sentence, replacing the dashed portion with a COMMA.
The result must be a structurally sound sentence.
A: 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 more flavorful and thus in increasing demand.
The subject in red lacks a verb.
Eliminate A.

B: Although heirloom tomatoes, grown from seeds saved during the previous year, appear less appetizing than most of their round and red supermarket cousins, heirlooms are more flavorful and thus in increasing demand.
This works.

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, heirlooms are more flavorful and thus in increasing demand.
The subject in red lacks a verb.
Eliminate C.

D: Grown from seeds saved during the previous year, heirloom tomatoes appear less appetizing than most of their round and red supermarket cousins, heirlooms are more flavorful and thus in increasing demand.
Here, a contrasting CONJUNCTION is needed to connect the two complete clauses: heirloom tomatoes appear less appetizing than most of their round and red supermarket cousins, BUT heirlooms are more flavorful.
Eliminate D.

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, heirlooms are more flavorful and thus in increasing demand.
The subject in red lacks a verb.
Eliminate E.
简单地说就是remove掉两个破折号之间的部分，然后所有选项的问题就显而易见了。
所以，我可不可以认为GMAC这是在考一个破折号的特殊用法，也就是所谓两个破折号之间的部分看作句子的插入语？
这么一来这题就变得灰常灰常简单了对嘛~

这道题是觉得OG的解释有点乱，看大家讨论的也挺多，就把找到的解释放上来啦~

从句子结构上选出这题的正确选项确实非常快，但是看了OG后，发现他们考察的东西还是很多，有很多需要我们考虑的地方。
比如它说，最好能把heirloom tomatoes主语尽可能提前；grown from seeds ...放在句首，使得这个信息太重要，有解释原因的嫌疑，即较严重的改变句意；
个人觉得，先从大方向，宏观上提取句子主干，像这题，可以很快定位正确答案，就算选不出正确答案，很多时候也可以迅速排出好几项错误答案。然后回过头来研究OG解释时，可以得到很多gmac的出题思路方面的收获
