语法与词汇 20.The women's organizations have been______in promoting women's rights, particularly the need to train women to assume responsibilities outside the domestic sphere.
【正确答案】 B
【答案解析】本题考查形容词辨析。由主语The women's organizations和宾语promoting women's rights可知，妇女组织是帮助促进妇女权利的，instrumental(起重要作用的)符合语义，故[B]项为答案。evocative意为“唤起感情的，引起回忆的”。preparatory意为“预备的，筹备的”。subordinate意为“隶属的；次要的”。
