题目解答
答案
B
解析
步骤 1：理解句子结构
句子的主句是 "Things might have been much worse"，这是一个虚拟语气的句子，表示对过去情况的假设。从句 "if the mother __________ on her right to keep the baby" 是一个条件从句，表示对过去情况的假设，因此从句应该使用过去完成时。
步骤 2：选择正确的时态
根据虚拟语气的规则，对过去情况的假设，从句应该使用过去完成时，即 "had + 过去分词"。因此，选项 B "had insisted" 是正确的。
步骤 3：验证答案
将 "had insisted" 代入句子，句子变为 "Things might have been much worse if the mother had insisted on her right to keep the baby."，符合虚拟语气的用法。
