题目解答
答案
D.had not been automated…would not have increased
解析
步骤 1:分析句子结构
句子的主句是 "the production _______ so greatly",而从句是 "If the workshop ______"。从句中的 "If" 表示假设,因此需要使用虚拟语气。
步骤 2:确定虚拟语气的时态
由于主句中的 "production" 是过去完成时,表示对过去的假设,因此从句应该使用过去完成时的虚拟语气,即 "had + 过去分词"。
步骤 3:选择正确的选项
选项 A 使用了 "were not automated",这是对现在或将来情况的假设,不符合题意。
选项 B 使用了 "had not automated",这是主动语态,不符合题意。
选项 C 使用了 "should not automated",这是对将来情况的假设,不符合题意。
选项 D 使用了 "had not been automated",这是被动语态,符合题意。
