《GMAT800揭秘》的SC一题

donna

For members of the seventeenth-century Ashanti nation in Africa, animal-hide shields with wooden frames were essential items of military equipment, a method to protect warriors against enemy arrows and spears.
A  a method to protect
B  as a method protecting
C  protecting
D  as a protection of
E  to protect

Why is the answer not E, but C?

OG上的解释
Choice C is best because the participle protecting begins a phrase that explains what the shields did. Choices A and B awkwardly use the singular word method to refer to items of military equipment rather than to the use of such items. Also, a method of protecting would be more idiomatic than a method to protect in A or a method protecting in B. In B and D, as is incorrect; also, a protection in D has no noun for which it can logically substitute. Choice E is incomplete; used to protect would have been acceptable.
感觉这里逗号后的成分不是表示目的，而是表示伴随状态。

这个解释我也看过了，只是就这种类型的题目老是不能很好的把握。
不知有何办法？你做的时候是怎么看的啊？

我觉得最关键是对原句逻辑意思的把握，主要是看这部分做什么成分，像这里只可能做短语修饰animal-hide shields，所以只能是分词而不能是不定式或同位语从句！

希望有所帮助！

首先很容易排除A、C、D，分词短语在句首、句尾表示伴随时，逻辑主语=句子主语，表示结果不用，所以PROTECTING的逻辑主语是animal-hide shields with wooden frames，而这里用动词不定式表示目的，按照动词不定式就近修饰的原则，其主语是military equipment，应该是不符合划线后的内容的描述。

我觉得OG讲得挺有道理，因为一个“ equipment”，相当于一个物，不可能是一种行为，只有“using a  equipment"才可能是“method ”和“protection ”。
