I was a bit out of control myself.A. shouldnt shoutB. shouldnt have shoutedC. mustnt shoutD. mustnt have shouted解析：选项D不存在首先排除。由句中的the other day 判断，说明指过去发生的事情，而A C 表示现在或将来，所以答案是B，表示“不应该做却做了”。(28)(2020山东24. )Thank you for all your hard work last week. I dont think we _ it without you.A. can manage B. could have managed C. could manage D. can have managed解析： 选项D不存在首先排除。句中的last week 表明事情发生在过去，所以，A错误，C could 是过去式，但could manage 并不能指过去发生的事情，而且这是一个否定前置的句子，表示“没有你我们不能完成这项工作”，所以答案B正确。(29)(2020江西27.)Where is my dictionary?

Would you be B. Should you be C. Could you be D. Might you be解析： 此题考查虚拟语气的特殊句式，所有的情态动词，只有should 可用于if 虚拟条件句的省略形式中。答案是B。四、 虚拟语气和真实语气相混合(31)(2020福建27.)If it were not for the fact that she _ sing, I would invite her to the party.A. couldnt B. shouldnt C. cant D. might not解析：此题从表面来看是一个虚拟语气的句子，但仔细分析发现句中的从句是一个事实：事实就是她不会唱歌。所以that引导从句是一个真实语气的句子，答案是C。六、测试平台1.
