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
關於這題,我想問A為什麼不可以
雖然句子的主語是shields ,用C來說明很合理
但是我可以這樣解釋嗎?
...military equipment , a method to protect.....
先略過method to 不好的用法
我可以說"這樣的軍事設備, 是一種方法去保護戰士對抗敵人的...."
我將a method 視為前面equipment的同位語,不知道可不可以???
