Another 20% worked well, but the remaining 60% should have been 【scrapped】.
A、scratched
B、renovated
C、stimulated
D、introduced
【正确答案】:B
【名师解析】:题目中的关键词 "should have been" 表示对过去情况的假设或建议。根据题目内容,有20%的情况是好的,但剩下的60%则需要采取某种措施。选项B "renovation" 意味着对某物进行翻新或修复,这与题目中提到的 "should have been" 相符合,表示对剩余部分的建议是进行翻新。而其他选项,如 "scratched"(划伤或取消),"stimulated"(刺激),和 "introduced"(介绍)都不符合题目的语境。因此,正确答案是B "renovation"。
