39. 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
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.
Would you please tell me why 'as' in B and D is incorrect?
Thanks
如果要加as,前面好像少了点东西,如used as...,要不不知道介词短语放这做何成分.另外,感觉也没必要,本来a method 和a protection修饰 shields就已经有作为...的意思了.罗嗦.
谢谢,我也感觉没有必要,但是OG是说这种用法错,有点不明白才问。你的看法我认为有道理。
首先, a protection in D has no noun for which it can logically substitute. 不是很能理解?
另外,对于as,刚才查了“英语语法大全”,没有发现d中的as使用有什么不对,请教大家!
最后, a method of protecting would be more idiomatic than a method to protect in A or a method protecting in B. 为什么用动名词会好些,请教!
谢谢!
怎么没有人回呢?
自己顶一下!
顶一下,我也是这个问题,为什么a method to 不行而要a method of ???
四楼的问题, 同问.

谢谢jerrold0023, 但是这个帖子以前看过了, 还是不理解四楼的问题?
哪位好心人帮忙解释一下!
四楼的问题我的想法是:
1. 代词的指代的问题本题的其它讨论帖已经说的非常详细, 不再赘述.
2. as和be动词搭配在意思上面比较的不清晰, 我查语法书上面的例子也屈指可数, 而且似乎应该放在前面, 比如, As a teacher, he is a good really one.
3. 我的认识层次就是这是个本idiomatic的说法, 一个经验数据是不定式作为定语修饰不好, 最起码不优选.
PS. 有兴趣的可以看看http://forum.chasedream.com/dispbbs.asp?boardID=23&ID=102002&page=1
对于不定式的定语问题, 尚没有定论.
对as 的用法,
as作介词时,结构是be +形容词+as,省略be后即 a.+as, 此时as前没有逗号,紧跟所补充修饰的词
as作连词,前面有逗号,结构是: 逗号+as+完整句子。
这题错误在于as 前有逗号,后又没有接句子成为连词,两不象。
个人看法,欢迎指正
