1）GWD原题:
Heirloom tomatoes, grown from seeds saved from the previous year, only look less appetizing than their round and red supermarket cousins, often green and striped, or have plenty of bumps and bruises, but are more flavorful.
A. cousins, often green and striped, or have plenty of bumps and bruises, but are
B. cousins, often green and striped, or with plenty of bumps and bruises, although
C. cousins, often green and striped, or they have plenty of bumps and bruises, although they are
D. cousins; they are often green and striped, or with plenty of bumps and bruises, although
E. cousins; they are often green and striped, or have plenty of bumps and bruises, but they are
答案是E。
A的问题：
1. often green and striped 的位置不好
-形容词只能做定语，需要紧跟被修饰成分，而且主句中已经出现修饰主语Heirloom tomatoes的分词定语grown from seeds saved from the previous year，因而让修饰成分often green and striped间隔出现修饰主语相当awkward。
2. often green and striped破坏对称性
-often green and striped， have plenty of bumps and bruises, are more flavorful. 作为描述主语的三部分应该结构对称。
E:
代词一般默认指代前面句子的主语
一种错误的解题思路：只要前面出现两个或两个以上的单数或复数名词，后面就不能再用代词。
GMAT很多SC例句都有这种情况出现，只要不容易引起歧义，是允许的，只是effectiveness上并不完美。 |
