选项 A、optional
B、potential
C、promising
D、alternative
答案 D
解析 本题考核的知识点是：形容词辨析+修饰成分。optional意为“可自由选择的”。如：English is an optional lesson．英语是选修课。potential意为“可能的，潜在的”。promising意为“有希望的，有前途的”。alternative意为“其他的，两者择一的”。如：The way was blocked．so we went by an alternative road．这条路被挡住了，因此我们走了另一条路。根据文章，制造纸张的方法还有其他可能的选择，只有alternative能够确切表达这层含义。
